Causes and Effects of Obesity Essay

Introduction, laziness as the main cause of obesity, social effects of obesity, effects of obesity: health complications.

Bibliography

Maintaining good body weight is highly recommended by medical doctors as a way of promoting a healthy status of the body. This is to say that there is allowed body weight, which a person is supposed to maintain. Extreme deviations from this weight expose a person to several health complications.

While being underweight is not encouraged, cases of people who are overweight and increasing effects of this condition have raised concerns over the need of addressing the issue of obesity in the society today, where statistics are rising day and night. What is obesity? This refers to a medical condition in which a person’s body has high accumulation of body fat to the level of being fatal or a cause of serious health complications. Additionally, obesity is highly associated with one’s body mass index, abbreviated as BMI.

This denotes the value obtained when a person’s weight in kilograms is divided by the square of their height in meters (Burniat 3). According to medical experts, obesity occurs when the BMI exceeds 30kg/m 2 . While this is the case, people who have a BMI of between 25 and 29 and considered to be overweight. Obesity has a wide-range of negative effects, which may be a threat to the life of a person.

The fist effect of obesity is that it encourages laziness in the society. It is doubtless that obese people find it hard and strenuous to move from one point to the other because of accumulated fats. As a result, most of these people lead a sedentary lifestyle, which is usually characterized by minimal or no movement. In such scenarios, victims prefer being helped doing basic activities, including moving from one point to another.

Moreover, laziness makes one to be inactive and unproductive. For example, a student who is obese may find it hard to attend to his or her homework and class assignments, thus affecting performance. With regard to physical exercises, obese people perceive exercises as punishment, which is not meant for them (Korbonits 265). As a result, they do not accept simple activities like jogging because of their inability to move.

In line with this, obese people cannot participate in games like soccer, athletics, and rugby among others. Based on this sedentary lifestyle, obese people spend a lot of their time watching television, movies, and playing video games, which worsen the situation.

The main effect of obesity is health complications. Research indicates that most of the killer diseases like diabetes, heart diseases, and high blood pressure are largely associated with obesity. In the United States, obesity-related complications cost the nation approximately 150 billion USD and result into 0.3 million premature deaths annually.

When there is increase in body fat, it means that the body requires more nutrients and oxygen to support body tissues (Burniat 223). Since these elements can only be transported by the blood to various parts of the body, the workload of the heart is increased.

This increase in the workload of the heart exerts pressure on blood vessels, leading to high blood pressure. An increase in the heart rate may also be dangerous due to the inability of the body to supply required blood to various parts. Moreover, obesity causes diabetes, especially among adults as the body may become resistant to insulin. This resistance may lead to a high level of blood sugar, which is fatal.

Besides health complications, obesity causes an array of psychological effects, including inferiority complex among victims. Obese people suffer from depression, emanating from negative self-esteem and societal rejection. In some cases, people who become obese lose their friends and may get disapproval from teachers and other personalities (Korbonits 265). This is mainly based on the assumption that people become obese due to lack of self-discipline. In extreme cases, obese people may not be considered for promotion at workplaces, because of the negative perception held against them.

Due to inferiority complex, obese people avoid being in public and prefer being alone. This is because they imagine how the world sees them and may also find it hard being involved in public activities because of their sizes.

This further makes them to consider themselves unattractive based on their deviation from what is considered as the normal body size and shape. Regardless of how obese people are treated, they always believe that they are being undermined because of their body size.

In summary, obesity is a major cause of premature deaths in the United States and around the world. This health condition occurs when there is excess accumulation of body fat, caused by unhealthy lifestyles. Obesity is largely associated with several killer diseases like high blood pressure, diabetes, and diseases of the heart.

These diseases drain world economies since most of them are fatal and expensive to manage. Additionally, obesity promotes sedentary life where victims minimize movement by adopting an inactive lifestyle. Moreover, obese victims suffer psychologically because of societal rejection. In general, obesity has a wide-range of negative effects, which may be a threat to the life of a person.

Obesity: Risk factors, complications, and strategies for sustainable long‐term weight management

Sharon m. fruh.

1 College of Nursing, University of South Alabama, Mobile, Alabama

Background and Purpose

The aims of this article are to review the effects of obesity on health and well‐being and the evidence indicating they can be ameliorated by weight loss, and consider weight‐management strategies that may help patients achieve and maintain weight loss.

Narrative review based on literature searches of PubMed up to May 2016 with no date limits imposed. Search included terms such as “obesity,” “overweight,” “weight loss,” “comorbidity,” “diabetes,” cardiovascular,” “cancer,” “depression,” “management,” and “intervention.”

Conclusions

Over one third of U.S. adults have obesity. Obesity is associated with a range of comorbidities, including diabetes, cardiovascular disease, obstructive sleep apnea, and cancer; however, modest weight loss in the 5%–10% range, and above, can significantly improve health‐related outcomes. Many individuals struggle to maintain weight loss, although strategies such as realistic goal‐setting and increased consultation frequency can greatly improve the success of weight‐management programs. Nurse practitioners have key roles in establishing weight‐loss targets, providing motivation and support, and implementing weight‐loss programs.

Implications for Practice

With their in‐depth understanding of the research in the field of obesity and weight management, nurse practitioners are well placed to effect meaningful changes in weight‐management strategies deployed in clinical practice.

Introduction

Obesity is an increasing, global public health issue. Patients with obesity are at major risk for developing a range of comorbid conditions, including cardiovascular disease (CVD), gastrointestinal disorders, type 2 diabetes (T2D), joint and muscular disorders, respiratory problems, and psychological issues, which may significantly affect their daily lives as well as increasing mortality risks. Obesity‐associated conditions are manifold; however, even modest weight reduction may enable patients to reduce their risk for CVD, diabetes, obstructive sleep apnea (OSA), and hypertension among many other comorbidities (Cefalu et al., 2015 ). A relatively small and simple reduction in weight, for example, of around 5%, can improve patient outcomes and may act as a catalyst for further change, with sustainable weight loss achieved through a series of incremental weight loss steps. In facilitating the process of losing weight for patients, nurse practitioners play an essential role. Through assessing the patient's risk, establishing realistic weight‐loss targets, providing motivation and support, and supplying patients with the necessary knowledge and treatment tools to help achieve weight loss, followed by tools for structured lifestyle support to maintain weight lost, the nurse practitioner is ideally positioned to help patient's achieve their weight‐loss—and overall health—targets.

The obesity epidemic

The World Health Organization (WHO) defines overweight and obesity as abnormal or excessive fat accumulation that presents a risk to health (WHO, 2016a ). A body mass index (BMI) ≥25 kg/m 2 is generally considered overweight, while obesity is considered to be a BMI ≥ 30 kg/m 2 . It is well known that obesity and overweight are a growing problem globally with high rates in both developed and developing countries (Capodaglio & Liuzzi, 2013 ; WHO, 2016a , 2016b ).

In the United States in 2015, all states had an obesity prevalence more than 20%, 25 states and Guam had obesity rates >30% and four of those 25 states (Alabama, Louisiana, Mississippi, and West Virginia) had rates >35% (Centres for Disease Control and Prevention, 2016 ; Figure ​ Figure1). 1 ). Approximately 35% and 37% of adult men and women, respectively, in the United States have obesity (Yang & Colditz, 2015 ). Adult obesity is most common in non‐Hispanic black Americans, followed by Mexican Americans, and non‐Hispanic white Americans (Yang & Colditz, 2015 ). Individuals are also getting heavier at a younger age; birth cohorts from 1966 to 1975 and 1976 to 1985 reached an obesity prevalence of ≥20% by 20–29 years of age, while the 1956–1965 cohort only reached this prevalence by age 30–39 years (Lee et al., 2010 ). Additionally, the prevalence of childhood obesity in 2‐ to 17‐year‐olds in the United States has increased from 14.6% in 1999–2000 to 17.4% in 2013–2014 (Skinner & Skelton, 2014 ). Childhood obesity is an increasing health issue because of the early onset of comorbidities that have major adverse health impacts, and the increased likelihood of children with obesity going on to become adults with obesity (50% risk vs. 10% for children without obesity; Whitaker, Wright, Pepe, Seidel, & Dietz, 1997 ).

Association of obesity with mortality and comorbid disease

Obesity is associated with a significant increase in mortality, with a life expectancy decrease of 5–10 years (Berrington de Gonzalez et al., 2010 ; Kuk et al., 2011 ; Prospective Studies Collaboration et al., 2009 ). There is evidence to indicate that all‐cause, CVD‐associated, and cancer‐associated mortalities are significantly increased in individuals with obesity, specifically those at Stages 2 or 3 of the Edmonton Obesity Staging System (EOSS; Kuk et al., 2011 ; Figure ​ Figure2). 2 ). Mortality related to cancer is, however, also increased at Stage 1, when the physical symptoms of obesity are marginal (Figure ​ (Figure2). 2 ). Recently, a large‐scale meta‐analysis that included studies that had enrolled over 10 million individuals, indicated that, relative to the reference category of 22.5 to <25 kg/m 2 , the hazard ratio (HR) for all‐cause mortality rose sharply with increasing BMI (The Global BMI Mortality Collaboration, 2016 ). For a BMI of 25.0 to <30.0 kg/m 2 , the HR was 1.11 (95% confidence interval [CI] 1.10, 1.11), and this increased to 1.44 (1.41, 1.47), 1.92 (1.86, 1.98), and 2.71 (2.55, 2.86) for a BMI of 30.0 to <35.0, 35.0 to <40.0, and 40.0 to <60.0 kg/m 2 , respectively.

Comorbidities

Obesity is a chronic disease that is associated with a wide range of complications affecting many different aspects of physiology (Dobbins, Decorby, & Choi, 2013 ; Guh et al., 2009 ; Martin‐Rodriguez, Guillen‐Grima, Marti, & Brugos‐Larumbe, 2015 ; summarized in Table ​ Table1). 1 ). To examine these obesity‐related morbidities in detail is beyond the scope of this review and therefore only a brief overview of some of the key pathophysiological processes is included next.

Morbidities associated with obesity (Hamdy, 2016 ; Petry, Barry, Pietrzak, & Wagner, 2008 ; Pi‐Sunyer, 2009 ; Sakai et al., 2005 ; Smith, Hulsey, & Goodnight, 2008 ; Yosipovitch, DeVore, & Dawn, 2007 )

The progression from lean state to obesity brings with it a phenotypic change in adipose tissue and the development of chronic low‐grade inflammation (Wensveen, Valentic, Sestan, Turk Wensveen, & Polic, 2015 ). This is characterized by increased levels of circulating free‐fatty acids, soluble pro‐inflammatory factors (such as interleukin [IL] 1β, IL‐6, tumor necrosis factor [TNF] α, and monocyte chemoattractant protein [MCP] 1) and the activation and infiltration of immune cells into sites of inflammation (Hursting & Dunlap, 2012 ). Obesity is also usually allied to a specific dyslipidemia profile (atherogenic dyslipidemia) that includes small, dense low‐density lipoprotein (LDL) particles, decreased levels of high‐density lipoprotein (HDL) particles, and raised triglyceride levels (Musunuru, 2010 ). This chronic, low‐grade inflammation and dyslipidemia profile leads to vascular dysfunction, including atherosclerosis formation, and impaired fibrinolysis. These, in turn, increase the risk for CVD, including stroke and venous thromboembolism (Blokhin & Lentz, 2013 ).

The metabolic and cardiovascular aspects of obesity are closely linked. The chronic inflammatory state associated with obesity is established as a major contributing factor for insulin resistance, which itself is one of the key pathophysiologies of T2D (Johnson, Milner, & Makowski, 2012 ). Furthermore, central obesity defined by waist circumference is the essential component of the International Diabetes Federation (IDF) definition of the metabolic syndrome (raised triglycerides, reduced HDL cholesterol, raised blood pressure, and raised fasting plasma glucose; International Diabetes Federation, 2006 ).

Obesity is also closely associated with OSA. To start, a number of the conditions associated with obesity such as insulin resistance (Ip et al., 2002 ), systemic inflammation, and dyslipidemia are themselves closely associated with OSA, and concurrently, the obesity‐associated deposition of fat around the upper airway and thorax may affect lumen size and reduce chest compliance that contributes to OSA (Romero‐Corral, Caples, Lopez‐Jimenez, & Somers, 2010 ).

The development of certain cancers, including colorectal, pancreatic, kidney, endometrial, postmenopausal breast, and adenocarcinoma of the esophagus to name a few, have also been shown to be related to excess levels of fat and the metabolically active nature of this excess adipose tissue (Booth, Magnuson, Fouts, & Foster, 2015 ; Eheman et al., 2012 ). Cancers have shown to be impacted by the complex interactions between obesity‐related insulin resistance, hyperinsulinemia, sustained hyperglycemia, oxidative stress, inflammation, and the production of adipokines (Booth et al., 2015 ). The wide range of morbidities associated with obesity represents a significant clinical issue for individuals with obesity. However, as significant as this array of risk factors is for patient health, the risk factors can be positively modified with weight loss.

Obesity‐related morbidities in children and adolescents

As was referred to earlier, children and adolescents are becoming increasingly affected by obesity. This is particularly concerning because of the long‐term adverse consequences of early obesity. Obesity adversely affects the metabolic health of young people and can result in impaired glucose tolerance, T2D, and early‐onset metabolic syndrome (Pulgaron, 2013 ).There is also strong support in the literature for relationships between childhood obesity and asthma, poor dental health (caries), nonalcoholic fatty liver disease (NAFLD), and gastroesophageal reflux disease (GERD; Pulgaron, 2013 ). Obesity can also affect growth and sexual development and may delay puberty in boys and advance puberty in some girls (Burt Solorzano & McCartney, 2010 ). Childhood obesity is also associated with hyperandrogenism and polycystic ovary syndrome (PCOS) in girls (Burt Solorzano & McCartney, 2010 ). Additionally, obesity is associated with psychological problems in young people including attention deficit hyperactivity disorder (ADHD), anxiety, depression, poor self‐esteem, and problems with sleeping (Pulgaron, 2013 ).

Modest weight loss and its long‐term maintenance: Benefits and risks

Guidelines endorse weight‐loss targets of 5%–10% in individuals with obesity or overweight with associated comorbidities, as this has been shown to significantly improve health‐related outcomes for many obesity‐related comorbidities (Cefalu et al., 2015 ; Figure ​ Figure3), 3 ), including T2D prevention, and improvements in dyslipidemia, hyperglycemia, osteoarthritis, stress incontinence, GERD, hypertension, and PCOS. Further benefits may be evident with greater weight loss, particularly for dyslipidemia, hyperglycemia, and hypertension. For NAFLD and OSA, at least 10% weight loss is required to observe clinical improvements (Cefalu et al., 2015 ).

Importantly, the weight‐loss benefits in terms of comorbidities are also reflected in improved all‐cause mortality. A recent meta‐analysis of 15 studies demonstrated that relatively small amounts of weight loss, on average 5.5 kg in the treatment arm versus 0.2 kg with placebo from an average baseline BMI of 35 kg/m 2 , resulted in a substantial 15% reduction in all‐cause mortality (Kritchevsky et al., 2015 ).

Cardiovascular health

Weight loss is associated with beneficial changes in several cardiovascular risk markers, including dyslipidemia, pro‐inflammatory/pro‐thrombotic mediators, arterial stiffness, and hypertension (Dattilo & Kris‐Etherton, 1992 ; Dengo et al., 2010 ; Goldberg et al., 2014 ; Haffner et al., 2005 ; Ratner et al., 2005 ). Importantly, weight loss was found to reduce the risk for CVD mortality by 41% up to 23 years after the original weight‐loss intervention (Li et al., 2014 ; Figure ​ Figure4). 4 ). Evidence including the biological effects of obesity and weight loss, and the increased risk for stroke with obesity indicates that weight loss may be effective for primary‐ and secondary‐stroke prevention (Kernan, Inzucchi, Sawan, Macko, & Furie, 2013 ).

Type 2 diabetes

Three major long‐term studies, the Diabetes Prevention Program (DPP), the Diabetes Prevention Study (DPS), and the Da Qing IGT and Diabetes (Da Qing) study, have demonstrated that modest weight loss through short‐term lifestyle or pharmacologic interventions can reduce the risk for developing T2D by 58%, 58%, and 31%, respectively, in individuals with obesity and prediabetes (DPP Research Group et al., 2009 ; Pan et al., 1997 ; Tuomilehto et al., 2001 ). Long‐term benefits were maintained following the interventions; for example, in the DPP, the risk reduction of developing T2D versus placebo was 34% at 10 years and 27% at 15 years following the initial weight‐loss intervention (DPP Research Group, 2015 ; DPP Research Group et al., 2009 ). Weight loss increased the likelihood of individuals reverting from prediabetes to normoglycemia (DPP Research Group et al., 2009 ; Li et al., 2008 ; Lindstrom et al., 2003 , 2006 ; Tuomilehto et al., 2001 ), and also improved other aspects of glycemic control including fasting and postprandial glucose, and insulin sensitivity (Haufe et al., 2013 ; Li et al., 2008 ).

Sleep apnea

Data indicate that weight loss is beneficial, although not curative, in patients with obesity who experience OSA. Meta‐analyses of patients who underwent treatment with either intensive lifestyle intervention (Araghi et al., 2013 ) or bariatric surgery (Greenburg, Lettieri, & Eliasson, 2009 ) demonstrated improvements in apnea‐hypopnea index (AHI) following treatment. In the first of these meta‐analyses, in randomized controlled trials, lifestyle intervention lead to a mean reduction in BMI of 2.3 kg/m 2 , which was associated with a decrease in mean AHI of 6.0 events/h. As expected, weight loss was much higher in the second meta‐analysis that investigated the effect of bariatric surgery on measures of OSA, and this was associated with greater reductions in AHI; the mean BMI reduction of 17.9 kg/m 2 resulted in AHI events being reduced by a mean of 38.2 events/h. Once these improvements in AHI have occurred, they seem to persist for some time, irrespective of a certain degree of weight regain. In one study, an initial mean weight loss of 10.7 kg resulted in a persistent improvement in AHI over a 4‐year period despite weight regain of approximately 50% by Year 4 (Kuna et al., 2013 ).

Intentional weight loss of >9 kg reduced the risk for a range of cancers including breast, endometrium, and colon in the large‐scale Iowa Women's Health Study (Parker & Folsom, 2003 ). The overall reduction in the incidence rate of any cancer was 11% (relative risk, 0.89; 95% CI 0.79, 1.00) for participants who lost more than 9 kg compared with those who did not achieve a more than 9 kg weight loss episode. Additionally, weight loss in participants with obesity has been established to be associated with reductions in cancer biomarkers including soluble E‐selectin and IL‐6 (Linkov et al., 2012 ).

Additional health benefits

The substantial weight loss associated with bariatric surgery has been shown to improve asthma with a 48%–100% improvement in symptoms and reduction in medication use (Juel, Ali, Nilas, & Ulrik, 2012 ); however, there is a potential threshold effect so that modest weight loss of 5%–10% may lead to clinical improvement (Lv, Xiao, & Ma, 2015 ). Similarly, modest weight loss of 5%–10% improves GERD (Singh et al., 2013 ) and liver function (Haufe et al., 2013 ). A study utilizing MRI scanning to examine the effects of weight loss on NAFLD has reported a reduction in liver fat from 18.3% to 13.6% ( p = .03), a relative reduction of 25% (Patel et al., 2015 ). Taking an active role in addressing obesity through behavioral modifications or exercise can also reduce the symptoms of depression (Fabricatore et al., 2011 ), improve urinary incontinence in men and women (Breyer et al., 2014 ; Brown et al., 2006 ), and improve fertility outcomes in women (Kort, Winget, Kim, & Lathi, 2014 ). Additionally, weight loss can reduce the joint‐pain symptoms and disability caused by weight‐related osteoarthritis (Felson, Zhang, Anthony, Naimark, & Anderson, 1992 ; Foy et al., 2011 ).

Mitigating risks

Despite the array of benefits, weight loss can also be linked with certain risks that may need to be managed. One such example is the risk for gallstones with rapid weight loss, which is associated with gallstone formation in 30%–71% of individuals. Gallstone formation is particularly associated with bariatric surgery when weight loss exceeds 1.5 kg/week and occurs particularly within the first 6 weeks following surgery when weight loss is greatest. Slower rates of weight loss appear to mitigate the risk for gallstone formation compared to the general population but may not eliminate it entirely; as was noted in the year‐long, weight‐loss, SCALE trial that compared liraglutide 3.0 mg daily use to placebo and resulted in gallstone formation in 2.5% of treated subjects compared to 1% of subjects taking placebo. For this reason, the risk for cholethiasis should be considered when formulating weight‐loss programs (Weinsier & Ullmann, 1993 ).

Strategies to help individuals achieve and maintain weight loss

Rogge and Gautam have covered the biology of obesity and weight regain within another section of this supplement (Rogge & Gautam, 2017 ), so here we focus on some of the clinical strategies for delivering weight loss and weight loss maintenance lifestyle programs. Structured lifestyle support plays an important role in successful weight management. A total of 34% of participants receiving structured lifestyle support from trained‐nursing staff achieved weight loss of ≥5% over 12 weeks compared with approximately 19% with usual care (Nanchahal et al., 2009 ). This particular structured program, delivered in a primary healthcare setting, included initial assessment and goal setting, an eating plan and specific lifestyle goals, personalized activity program, and advice about managing obstacles to weight loss. Additionally, data from the National Weight Control Registry (NWCR), which is the longest prospective compilation of data from individuals who have successfully lost weight and maintained their weight loss, confirm expectations that sustained changes to both diet and activity levels are central to successful weight management (Table ​ (Table2). 2 ). Therefore, an understanding of different clinical strategies for delivery‐structured support is essential for the nurse practitioner.

Lifestyle factors associated with achieving and maintaining weight loss

a Walking was the most common activity undertaken.

Realistic weight‐loss targets

From the outset, a patient's estimate of their achievable weight loss may be unrealistic. Setting realistic weight‐loss goals is often difficult because of misinformation from a variety of sources, including friends, media, and other healthcare professionals (Osunlana et al., 2015 ). Many individuals with obesity or overweight have unrealistic goals of 20%–30% weight loss, whereas a more realistic goal would be the loss of 5%–15% of the initial body weight (Fabricatore et al., 2007 ). Promoting realistic weight‐loss expectations for patients was identified as a key difficulty for nurse practitioners, primary care nurses, dieticians, and mental health workers (Osunlana et al., 2015 ). Visual resources showing the health and wellness benefit of modest weight loss may thus be helpful (Osunlana et al., 2015 ). Healthcare practitioners should focus on open discussion about, and re‐enforcement of, realistic weight‐loss goals and assess outcomes consistently according to those goals (Bray, Look, & Ryan, 2013 ).

Maintaining a food diary

The 2013 White Paper from the American Nurse Practitioners Foundation on the Prevention and Treatment of Obesity considers a food diary as an important evidence‐based nutritional intervention in aiding weight loss (ANPF). Consistent and regular recording in a food diary was significantly associated with long‐term weight‐loss success in a group of 220 women (Peterson et al., 2014 ). This group lost a mean of 10.4% of their initial body weight through a 6‐month group‐based weight‐management program and then regained a mean of 2.3% over a 12‐month follow‐up period, during which participants received bimonthly support in person, by telephone, or by e‐mail (Peterson et al., 2014 ). Over the 12‐month follow‐up, women who self‐monitored consistently (≥50% of the extended‐care year) had a mean weight loss of 0.98%, while those who were less consistent (<50%) gained weight (5.1%; p < .01). Therefore, frequent and consistent food monitoring should be encouraged, particularly in the weight‐maintenance phase of any program.

Motivating and supporting patients

Motivational interviewing is a technique that focuses on enhancing intrinsic motivation and behavioral changes by addressing ambivalence (Barnes & Ivezaj, 2015 ). Interviews focus on “change talk,” including the reasons for change and optimism about the intent for change in a supportive and nonconfrontational setting, and may help individuals maintain behavioral changes.

For patients that have achieved weight loss, the behavioral factors associated with maintaining weight loss include strong social support networks, limiting/avoiding disinhibited eating, avoiding binge eating, avoiding eating in response to stress or emotional issues, being accountable for one's decisions, having a strong sense of autonomy, internal motivation, and self‐efficacy (Grief & Miranda, 2010 ). Therefore, encouraging feelings of “self‐worth” or “self‐efficacy” can help individuals to view weight loss as being within their own control and achievable (Cochrane, 2008 ).

Strengthening relationships with patients with overweight or obesity to enhance trust may also improve adherence with weight‐loss programs. Patients with hypertension who reported having “complete trust” in their healthcare practitioner were more than twice as likely to engage in lifestyle changes to lose weight than those who lacked “complete trust” (Jones, Carson, Bleich, & Cooper, 2012 ). It may be prudent to ensure the healthcare staff implementing weight‐loss programs have sufficient time to foster trust with their patients.

Continued support from healthcare staff may help patients sustain the necessary motivation for lifestyle changes. A retrospective analysis of 14,256 patients in primary care identified consultation frequency as a factor that can predict the success of weight‐management programs (Lenoir, Maillot, Guilbot, & Ritz, 2015 ). Individuals who successfully maintained ≥10% weight loss over 12 months visited the healthcare provider on average 0.65 times monthly compared with an average of 0.48 visits/month in those who did not maintain ≥10% weight loss, and 0.39 visits/month in those who failed to achieve the initial ≥10% weight loss ( p < .001; Lenoir et al., 2015 ).

Educational and environmental factors

It is important to consider a patient's education and environment when formulating a weight loss strategy as environmental factors may need to be challenged to help facilitate weight loss. A family history of obesity and childhood obesity are strongly linked to adult obesity, which is likely to be because of both genetic and behavioral factors (Kral & Rauh, 2010 ). Parents create their child's early food experiences and influence their child's attitudes to eating through learned eating habits and food choices (Kral & Rauh, 2010 ). Families can also impart cultural preferences for less healthy food choices and family food choices may be affected by community factors, such as the local availability and cost of healthy food options (Castro, Shaibi, & Boehm‐Smith, 2009 ). Alongside this, genetic variation in taste sensation may influence the dietary palate and influence food choices (Loper, La Sala, Dotson, & Steinle, 2015 ). For example, sensitivity to 6‐n‐propylthiouracil (PROP) is genetically determined, and PROP‐tasting ability ranges from super taster to nontaster. When offered buffet‐style meals over 3 days, PROP nontasters consumed more energy, and a greater proportion of energy from fat compared with super tasters. So it is possible that a family's genetic profile could contribute to eating choices. To address behavioral factors, it is important to ensure that families have appropriate support and information and that any early signs of weight gain are dealt with promptly.

A healthy home food environment can help individuals improve their diet. In children, key factors are availability of fresh fruit and vegetables at home and parental influence through their own fresh fruit and vegetable intake (Wyse, Wolfenden, & Bisquera, 2015 ). In adults, unhealthy home food environment factors include less healthy food in the home and reliance on fast food ( p = .01) are all predictors of obesity (Emery et al., 2015 ).

Family mealtimes are strongly associated with better dietary intake and a randomized controlled trial to encourage healthy family meals showed a promising reduction in excess weight gain in prepubescent children (Fulkerson et al., 2015 ). Another study showed that adolescents with any level of baseline family meal frequency, 1–2, 3–4, and ≥5 family meals/week, had reduced odds of being affected by overweight or obesity 10 years later than adolescents who never ate family meals (Berge et al., 2015 ). Community health advocates have identified the failure of many families to plan meals or prepare food as a barrier to healthy family eating patterns (Fruh, Mulekar, Hall, Fulkerson et al., 2013 ). Meal planning allows healthy meals to be prepared in advance and frozen for later consumption (Fruh, Mulekar, Hall, Adams et al., 2013 ) and is associated with increased consumption of vegetables and healthier meals compared with meals prepared on impulse (Crawford, Ball, Mishra, Salmon, & Timperio, 2007 ; Hersey et al., 2001 ).

The role of the nurse practitioner

The initial and ongoing interactions between patient and nurse practitioner are keys for the determination of an effective approach and implementation of a weight loss program and subsequent weight maintenance. The initial interaction can be instigated by either the nurse practitioner or the patient and once the decision has been made to manage the patient's weight, the evaluation includes a risk assessment, a discussion about the patient's weight, and treatment goal recommendations (American Nurse Practitioner Foundation, 2013 ). Across this process, it may be advantageous to approach this using objective data and language that is motivational and/or nonjudgmental. Patients may struggle with motivation, and therefore, ongoing discussions around the health benefits and improvements to quality of life as a result of weight loss may be required (American Nurse Practitioner Foundation, 2013 ). It may be valuable to allocate personalized benefits to the weight loss such as playing with children/grandchildren (American Nurse Practitioner Foundation, 2013 ). Treatment approaches encompass nonpharmacological and pharmacological strategies; however, it is important to remember that any pharmacological agent used should be used as an adjunct to nutritional and physical activity strategies (American Nurse Practitioner Foundation, 2013 ). Pharmacotherapy options for weight management are discussed further in the article by Golden in this supplement.

Conclusions/summary

The importance of obesity management is underscored both by the serious health consequences for individuals, but also by its increasing prevalence globally, and across age groups in particular. Obesity promotes a chronic, low‐grade, inflammatory state, which is associated with vascular dysfunction, thrombotic disorders, multiple organ damage, and metabolic dysfunction. These physiological effects ultimately lead to the development of a range of morbidities, including CVD, T2D, OSA, and certain cancers along with many others, as well as causing a significant impact on mortality.

However, even modest weight loss of 5%–10% of total body weight can significantly improve health and well‐being, and further benefits are possible with greater weight loss. Weight loss can help to prevent development of T2D in individuals with obesity and prediabetes and has a positive long‐term impact on cardiovascular mortality. Beneficial, although not curative, effects have also been noted on OSA following >10% weight loss. In addition, weight loss reduces the risk for certain cancer types and has positive effects on most comorbidities including asthma, GERD, liver function, urinary incontinence, fertility, joint pain, and depression.

Weight‐loss programs that include realistic weight loss goals, frequent check‐in, and meal/activity diaries may help individuals to lose weight. Setting realistic weight‐loss goals can be difficult; however, visual resources showing the health and wellness benefit of weight loss may be helpful in discussing realistic goals, and help motivate the patient in maintaining the weight loss. Techniques such as motivational interviewing that focus on addressing resistance to behavioral change in a supportive and optimistic manner may help individuals in integrating these changes to allow them to become part of normal everyday life and thus help with maintaining the weight loss. Positive reinforcement in terms of marked early‐weight loss may also assist in improving adherence, so this should be a key goal for weight‐loss programs. Encouraging feelings of “self‐worth” or “self‐efficacy” can help individuals to view weight loss as being within their own control.

Nurse practitioners play a major role in helping patients achieve weight loss through all aspects of the process including assessment, support, motivation, goal‐setting, management, and treatment. With their in‐depth understanding of the research in the field of obesity and weight management, nurse practitioners are well placed to effect meaningful changes in the weight‐management strategies deployed in clinical practice.

10.8 Cause and Effect

Learning objectives.

• Determine the purpose and structure of cause and effect in writing.
• Understand how to write a cause-and-effect essay.

The Purpose of Cause and Effect in Writing

It is often considered human nature to ask, “why?” and “how?” We want to know how our child got sick so we can better prevent it from happening in the future, or why our colleague a pay raise because we want one as well. We want to know how much money we will save over the long term if we buy a hybrid car. These examples identify only a few of the relationships we think about in our lives, but each shows the importance of understanding cause and effect.

A cause is something that produces an event or condition; an effect is what results from an event or condition. The purpose of the cause-and-effect essay is to determine how various phenomena relate in terms of origins and results. Sometimes the connection between cause and effect is clear, but often determining the exact relationship between the two is very difficult. For example, the following effects of a cold may be easily identifiable: a sore throat, runny nose, and a cough. But determining the cause of the sickness can be far more difficult. A number of causes are possible, and to complicate matters, these possible causes could have combined to cause the sickness. That is, more than one cause may be responsible for any given effect. Therefore, cause-and-effect discussions are often complicated and frequently lead to debates and arguments.

Use the complex nature of cause and effect to your advantage. Often it is not necessary, or even possible, to find the exact cause of an event or to name the exact effect. So, when formulating a thesis, you can claim one of a number of causes or effects to be the primary, or main, cause or effect. As soon as you claim that one cause or one effect is more crucial than the others, you have developed a thesis.

Consider the causes and effects in the following thesis statements. List a cause and effect for each one on your own sheet of paper.

• The growing childhood obesity epidemic is a result of technology.
• Much of the wildlife is dying because of the oil spill.
• The town continued programs that it could no longer afford, so it went bankrupt.
• More young people became politically active as use of the Internet spread throughout society.
• While many experts believed the rise in violence was due to the poor economy, it was really due to the summer-long heat wave.

Write three cause-and-effect thesis statements of your own for each of the following five broad topics.

• Health and nutrition

The Structure of a Cause-and-Effect Essay

The cause-and-effect essay opens with a general introduction to the topic, which then leads to a thesis that states the main cause, main effect, or various causes and effects of a condition or event.

The cause-and-effect essay can be organized in one of the following two primary ways:

• Start with the cause and then talk about the effects.
• Start with the effect and then talk about the causes.

For example, if your essay were on childhood obesity, you could start by talking about the effect of childhood obesity and then discuss the cause or you could start the same essay by talking about the cause of childhood obesity and then move to the effect.

Regardless of which structure you choose, be sure to explain each element of the essay fully and completely. Explaining complex relationships requires the full use of evidence, such as scientific studies, expert testimony, statistics, and anecdotes.

Because cause-and-effect essays determine how phenomena are linked, they make frequent use of certain words and phrases that denote such linkage. See Table 10.4 “Phrases of Causation” for examples of such terms.

Table 10.4 Phrases of Causation

The conclusion should wrap up the discussion and reinforce the thesis, leaving the reader with a clear understanding of the relationship that was analyzed.

Be careful of resorting to empty speculation. In writing, speculation amounts to unsubstantiated guessing. Writers are particularly prone to such trappings in cause-and-effect arguments due to the complex nature of finding links between phenomena. Be sure to have clear evidence to support the claims that you make.

Look at some of the cause-and-effect relationships from Note 10.83 “Exercise 2” . Outline the links you listed. Outline one using a cause-then-effect structure. Outline the other using the effect-then-cause structure.

Writing a Cause-and-Effect Essay

Choose an event or condition that you think has an interesting cause-and-effect relationship. Introduce your topic in an engaging way. End your introduction with a thesis that states the main cause, the main effect, or both.

Organize your essay by starting with either the cause-then-effect structure or the effect-then-cause structure. Within each section, you should clearly explain and support the causes and effects using a full range of evidence. If you are writing about multiple causes or multiple effects, you may choose to sequence either in terms of order of importance. In other words, order the causes from least to most important (or vice versa), or order the effects from least important to most important (or vice versa).

Use the phrases of causation when trying to forge connections between various events or conditions. This will help organize your ideas and orient the reader. End your essay with a conclusion that summarizes your main points and reinforces your thesis. See Chapter 15 “Readings: Examples of Essays” to read a sample cause-and-effect essay.

Choose one of the ideas you outlined in Note 10.85 “Exercise 3” and write a full cause-and-effect essay. Be sure to include an engaging introduction, a clear thesis, strong evidence and examples, and a thoughtful conclusion.

Key Takeaways

• The purpose of the cause-and-effect essay is to determine how various phenomena are related.
• The thesis states what the writer sees as the main cause, main effect, or various causes and effects of a condition or event.

The cause-and-effect essay can be organized in one of these two primary ways:

• Start with the cause and then talk about the effect.
• Start with the effect and then talk about the cause.
• Strong evidence is particularly important in the cause-and-effect essay due to the complexity of determining connections between phenomena.
• Phrases of causation are helpful in signaling links between various elements in the essay.

26 Conclusion: Obesity and its prevention in the 21st century

• Published: September 2010
• Cite Icon Cite
• Permissions Icon Permissions

The case for a preventative approach to the obesity epidemic is compelling. Obesity poses what is arguably one of the most significant threats to population health that is currently faced. The data presented in this book highlight just how common obesity has become in children and in adults across the globe, and how it impacts disproportionately on the poor. This chapter presents a summary of the discussions in the preceding chapters.

Learning Objectives

• Determine the purpose and structure of cause and effect in writing.
• Understand how to write a cause-and-effect essay.

The Purpose of Cause and Effect in Writing

It is often considered human nature to ask, “why?” and “how?” We want to know how our child got sick so we can better prevent it from happening in the future, or why our colleague a pay raise because we want one as well. We want to know how much money we will save over the long term if we buy a hybrid car. These examples identify only a few of the relationships we think about in our lives, but each shows the importance of understanding cause and effect.

A cause is something that produces an event or condition; an effect is what results from an event or condition. The purpose of the cause-and-effect essay is to determine how various phenomena relate in terms of origins and results. Sometimes the connection between cause and effect is clear, but often determining the exact relationship between the two is very difficult. For example, the following effects of a cold may be easily identifiable: a sore throat, runny nose, and a cough. But determining the cause of the sickness can be far more difficult. A number of causes are possible, and to complicate matters, these possible causes could have combined to cause the sickness. That is, more than one cause may be responsible for any given effect. Therefore, cause-and-effect discussions are often complicated and frequently lead to debates and arguments.

Use the complex nature of cause and effect to your advantage. Often it is not necessary, or even possible, to find the exact cause of an event or to name the exact effect. So, when formulating a thesis, you can claim one of a number of causes or effects to be the primary, or main, cause or effect. As soon as you claim that one cause or one effect is more crucial than the others, you have developed a thesis.

Exercise \(\PageIndex{1}\)

Consider the causes and effects in the following thesis statements. List a cause and effect for each one on your own sheet of paper.

• The growing childhood obesity epidemic is a result of technology.
• Much of the wildlife is dying because of the oil spill.
• The town continued programs that it could no longer afford, so it went bankrupt.
• More young people became politically active as use of the Internet spread throughout society.
• While many experts believed the rise in violence was due to the poor economy, it was really due to the summer-long heat wave.

Exercise \(\PageIndex{2}\)

Write three cause-and-effect thesis statements of your own for each of the following five broad topics.

• Health and nutrition

The Structure of a Cause-and-Effect Essay

The cause-and-effect essay opens with a general introduction to the topic, which then leads to a thesis that states the main cause, main effect, or various causes and effects of a condition or event.

The cause-and-effect essay can be organized in one of the following two primary ways:

• Start with the cause and then talk about the effects.
• Start with the effect and then talk about the causes.

For example, if your essay were on childhood obesity, you could start by talking about the effect of childhood obesity and then discuss the cause or you could start the same essay by talking about the cause of childhood obesity and then move to the effect.

Regardless of which structure you choose, be sure to explain each element of the essay fully and completely. Explaining complex relationships requires the full use of evidence, such as scientific studies, expert testimony, statistics, and anecdotes.

Because cause-and-effect essays determine how phenomena are linked, they make frequent use of certain words and phrases that denote such linkage. See Table \(\PageIndex{1}\): “Phrases of Causation” for examples of such terms.

Table \(\PageIndex{1}\): Phrases of Causation

The conclusion should wrap up the discussion and reinforce the thesis, leaving the reader with a clear understanding of the relationship that was analyzed.

Be careful of resorting to empty speculation. In writing, speculation amounts to unsubstantiated guessing. Writers are particularly prone to such trappings in cause-and-effect arguments due to the complex nature of finding links between phenomena. Be sure to have clear evidence to support the claims that you make.

Exercise \(\PageIndex{3}\)

Look at some of the cause-and-effect relationships from Note 10.83 “Exercise 2” . Outline the links you listed. Outline one using a cause-then-effect structure. Outline the other using the effect-then-cause structure.

Writing a Cause-and-Effect Essay

Choose an event or condition that you think has an interesting cause-and-effect relationship. Introduce your topic in an engaging way. End your introduction with a thesis that states the main cause, the main effect, or both.

Organize your essay by starting with either the cause-then-effect structure or the effect-then-cause structure. Within each section, you should clearly explain and support the causes and effects using a full range of evidence. If you are writing about multiple causes or multiple effects, you may choose to sequence either in terms of order of importance. In other words, order the causes from least to most important (or vice versa), or order the effects from least important to most important (or vice versa).

Use the phrases of causation when trying to forge connections between various events or conditions. This will help organize your ideas and orient the reader. End your essay with a conclusion that summarizes your main points and reinforces your thesis. See below to read a sample cause-and-effect essay:

Effects of Video Game Addiction

Video game addition is a serious problem in many parts of the world today and deserves more attention. It is no secret that children and adults in many countries throughout the world, including Japan, China, and the United States, play video games every day. Most players are able to limit their usage in ways that do not interfere with their daily lives, but many others have developed an addiction to playing video games and suffer detrimental effects.

An addiction can be described in several ways, but generally speaking, addictions involve unhealthy attractions to substances or activities that ultimately disrupt the ability of a person to keep up with regular daily responsibilities. Video game addiction typically involves playing games uncontrollably for many hours at a time—some people will play only four hours at a time while others cannot stop for over twenty-four hours. Regardless of the severity of the addiction, many of the same effects will be experienced by all.

One common effect of video game addiction is isolation and withdrawal from social experiences. Video game players often hide in their homes or in Internet cafés for days at a time—only reemerging for the most pressing tasks and necessities. The effect of this isolation can lead to a breakdown of communication skills and often a loss in socialization. While it is true that many games, especially massive multiplayer online games, involve a very real form of e-based communication and coordination with others, and these virtual interactions often result in real communities that can be healthy for the players, these communities and forms of communication rarely translate to the types of valuable social interaction that humans need to maintain typical social functioning. As a result, the social networking in these online games often gives the users the impression that they are interacting socially, while their true social lives and personal relations may suffer.

Another unfortunate product of the isolation that often accompanies video game addiction is the disruption of the user’s career. While many players manage to enjoy video games and still hold their jobs without problems, others experience challenges at their workplace. Some may only experience warnings or demerits as a result of poorer performance, or others may end up losing their jobs altogether. Playing video games for extended periods of time often involves sleep deprivation, and this tends to carry over to the workplace, reducing production and causing habitual tardiness.

Video game addiction may result in a decline in overall health and hygiene. Players who interact with video games for such significant amounts of time can go an entire day without eating and even longer without basic hygiene tasks, such as using the restroom or bathing. The effects of this behavior pose significant danger to their overall health.

The causes of video game addiction are complex and can vary greatly, but the effects have the potential to be severe. Playing video games can and should be a fun activity for all to enjoy. But just like everything else, the amount of time one spends playing video games needs to be balanced with personal and social responsibilities.

IELTS Causes and Effects Essay: Obesity in Children

This causes and effects model essay is about  obesity in children.

You specifically have to talk about the  causes  (reasons) of the increase in overweight children, and explain the  effects  (results) of this.

Here is the question:

The percentage of overweight children in western society has increased by almost 20% in the last ten years.

Discuss the causes and effects of this disturbing trend.

Thinking about Coherence & Cohesion

This particular essay is organized as follows:

• Body 1: Causes
• Body 2: Effects

Of course it is also possible to have a 3 body paragraph essay. For example

However, remember not to write too little on one part.

For example, if you wrote one very short paragraph about 'causes' with little support and most of your essay on 'effects', you may then be seen to have not fully answered both parts of the question.

Another possible way of organizing it is to put each cause and its effect within a separate paragraph:

• Body 1: Cause 1 - Effect
• Body 2: Cause 2 - Effect

If you do this though, each particular cause must relate to that specific effect.

Example Child Obesity Essay

You should spend about 40 minutes on this task.

Write about the following topic:

Give reasons for your answer and include any relevant examples from your own experience or knowledge.

Write at least 250 words.

Causes and Effects Essay - Model Answer

Over the last ten years, western societies have seen close to a 20% rise in the number of children who are overweight. This essay will discuss some reasons why this has occurred and examine the consequences of this worrying trend.

The main cause of this problem is poor diet. Over the last decade there has been a prolific increase in the number of fast food restaurants. For example, on nearly every high street there is a MacDonald’s, Kentucky Fried Chicken and Pizza Hut. The food in these places has been proven to be very unhealthy, and much of the advertising is targeted at children, thus ensuring that they constitute the bulk of the customers of these establishments. However, it is not only due to eating out, but also the type of diet many children have at home. A lot of food consumed is processed food, especially with regards to ready-made meals which are a quick and easy option for parents who are working hard.

The effects of this have been and will continue to be very serious. Firstly, there has been a large increase in health related diseases amongst children, especially diabetes. This debilitating illness means a child has to be injected with insulin for the rest of their life. Not only this, very overweight children often experience bullying from other children, which may affect their mental health. The negative stigma of being overweight may also affect self-esteem.

To sum up, it is evident that there are several causes of obesity amongst children, and a variety of negative effects. Society must ensure steps are taken to prevent this problem from deteriorating further.

How to write cause/effect essays in IELTS?

Cause and effect essay questions in IELTS Writing task 2 give you a problem and ask you to state the main causes of this problem and discuss its possible effects .

In this lesson you will see:

• how to generate ideas for causes and effects
• band 9 answer structure for causes/effects essay
• cause/effect model essay

This is an example of cause/effect IELTS writing task 2 question:

Today more people are overweight than ever before.

What in your opinion are the primary causes of this?

What are the main effects of this epidemic?

Generating ideas

After you’ve read the question, you can clearly determine the problem: growing number of overweight people .

But before you start to write your essay, it’s a good idea to think of 2-3 causes and 2-3 possible effects of the problem.

Causes of obesity :

• inactive lifestyle (relying on cars instead of walking, fewer physical demands at work, inactive leisure activities)
• unhealthy eating habits (eating fast-food, drinking high-calorie beverages, consuming large portions of food, eating irregularly)

Effects of obesity :

• physical health problems
• loss of productivity
• depressions and mental disorders

Now, after we’ve generated the main ideas for causes and effects, it’s time to use these ideas in our essay.

Band 9 answer structure

As you know, there are many ways to structure your essay, but we’ll use a structure that has been approved by many IELTS examiners to be high-scoring and coherent .

Band-9 essay structure :

Introduction

Body paragraph 1 - causes

Body paragraph 2 - effects

Let’s take a look at each of these sections in detail.

Write your introduction in two sentences:

Nowadays the number of overweight people is constantly growing.

This essay will discuss the main reasons of this epidemic and then describe the possible effects of the problem.

In my opinion, the foremost causes of obesity are inactive lifestyle and unhealthy eating habits.

Today more and more people rely on cars instead of walking, have less physical demands at work and prefer inactive leisure activities. This results in burning less calories and gaining weight.

Moreover, the problem is accentuated by the growing number of people, who eat irregularly and consume large portions of high-calorie food. For example, about 50% of the adult population in Europe with so-called disordered eating suffer from obesity.

The possible effects of this problem include physical health problems and loss of productivity.

First of all, obesity results in incorrect functioning of the human body and contributes to the risk of developing some chronic illnesses. For example, as body fat percentage increases, the person’s metabolism worsens, which in turn may result in diabetes or heart diseases.

Secondly, overweight people are very unhealthy and often suffer from stress and tiredness. This lessens their work capacity and results in lower productivity. For example, it has been proven that an obese person needs to put more effort to complete some task than a person with normal weight.

For the conclusion you need simply to restate the problem and sum up the causes and effects that you described in your body paragraphs:

To sum up, obesity is a big problem that affects a lot of people nowadays. It’s mainly caused by inactive lifestyle and eating disorders and results in severe health problems and loss of productivity.
