“…In support of this, across three large nationally representative samples of the US and UK adults, individuals who identified that they were overweight went on to gain more weight than those who did not identify that they were overweight 124. This same basic finding has also been observed among adolescents and young adults; overweight adolescents and young adults who correctly identify that they are overweight are at a greater risk of future elevated weight gain compared with those who fail to identify that they are overweight 125, 126, 127. How these findings relate to the earlier discussed observation that a person identifying his or her weight status as being overweight is associated with a greater desire to lose weight is important to consider.…”

SummaryAlthough overweight and obesity are widespread across most of the developed world, a considerable body of research has now accumulated, which suggests that adiposity often goes undetected. A substantial proportion of individuals with overweight or obesity do not identify they are overweight, and large numbers of parents of children with overweight or obesity fail to identify their child as being overweight. Lay people and medical practitioners are also now poor at identifying overweight and obesity in others. A visual normalization theory of the under‐detection of overweight and obesity is proposed. This theory is based on the notion that weight status is judged relative to visual body size norms. Because larger body sizes are now common, this has caused a recalibration to the range of body sizes that are perceived as being ‘normal’ and increased the visual threshold for what constitutes ‘overweight’. Evidence is reviewed that indicates this process has played a significant role in the under‐detection of overweight and obesity. The public health relevance of the under‐detection of overweight and obesity is also discussed.

“…Given this, clinical interventions for youths who are depressed and obese perhaps should consider including strategies which focus on weight control as well as improving body image and symptoms of depression. For example, our previous study (Duong and Roberts, 2014) found that those who perceived themselves as skinny at baseline were 60% less likely to be overweight at followup. In this case perceiving one’s self as thin protected against future risk of overweight.…”

Objective The purpose of this paper is to reexamine the association between major depression and obesity in adolescents, testing the hypothesis that body image mediates this association. This is the first paper to examine this question using DSM-IV diagnosis of depression and data from a two-wave cohort of adolescents. Methods Participants were 4,175 youths 11–17 years of age sampled from the community who were followed up a year later (n = 3,134). Major depression was assessed using DSM-IV diagnostic criteria. Body image was measured with perceived weight. Obesity was defined as BMI > 95th percentile using measured height and weight. Results When we examined a model which included obesity, perceived weight, major depression and covariates, there was no association between major depression at baseline and obesity at follow-up. We found no independent association between major depression and body weight. Limitations The study was limited in that it is not a national sample, BMI was the only measure of adiposity, perceived weight was the only measure of body image, and there were no data on lifetime trajectories of depression, obesity, or body image. Conclusions If there is an etiologic link between major depression and body weight among adolescents, it most likely operates through processes involving components of body image, since controlling for body image eliminated the association between depression and obesity. Clinically, addressing body image in depressed patients who are obese may improve outcomes.

“…This may be due to low power. It also could be the result of the effects of factors such as body image [58, 61], as well as unmeasured factors.…”

Objective This is the first prospective study of the reciprocal association between sleep restriction and weight among adolescents. Evidence on sleep duration and obesity in youth is sparse and the results have been equivocal. Methods Data are from a community-based, two-wave cohort study. The setting was a metropolitan area with a population of over 4 million. The cohort consisted of 4,175 youths 11–17 at baseline and 3,134 of these followed up a year later. Obesity was defined as body mass index ≥ 95th percentile for children of the same age and sex. Sleep restriction was defined as 6 or fewer hours of sleep per night on weeknights or on both weekends and weeknights. Covariates examined were age, gender, family income and depression. Results Results clearly demonstrated there was no association between sleep restriction and obesity at baseline. In prospective analyses, sleep restriction did not increase future risk of obesity, nor did obesity increase risk of future sleep restriction. Conclusions These findings call into question previous research based primarily on cross-sectional data suggesting a positive correlation between sleep restriction and obesity. However, the results for adolescents in this study are supported by one study of adolescents and by studies of adults using prospective designs. At this point, there appears to be little evidence for a temporal relation between sleep duration and obesity among adults or adolescents.
