“…More men (~53%) than women (~30%) perceived their weight inaccurately, and significantly more Sami women (34.4%) compared with non-Sami women (29.8%) underestimated their overweight/obesity. The discrepancy between women and men highly agrees with most studies published, and many of these are based on different ethnic populations 4 31 35–37. A study of Caribbean adults aged >40 years, however, showed equal sex distribution 38.…”

ObjectivesUnderestimation of overweight/obesity may prevent weight loss attempts, resulting in further weight gain and maintenance of overweight. Mental health benefits may nevertheless surpass negative consequences. Our main objective was to study the association between underestimation of overweight/obesity and symptoms of anxiety and depression in Sami and non-Sami populations.DesignPopulation-based cross-sectional study.SettingThe SAMINOR 2 Clinical Study with participants from 10 municipalities in Northern Norway enrolled between 2012 and 2014.ParticipantsThe study included 3266 adults of multiethnic rural origin with overweight/obesity (body mass index (BMI) ≥25 kg/m2) whereof 1384 underestimated their weight (42%).Primary and secondary outcome measuresPrimary outcome measure was symptoms of anxiety and depression and secondary outcome measures were BMI and the demographic variables: sex, age, education and marital status.ResultsA higher proportion of Sami men compared with non-Sami men were obese, and reported more symptoms of anxiety and depression. More men than women, and a higher proportion of Sami women compared with non-Sami women, underestimated their weight. Multivariable-adjusted analyses showed that women were less likely to underestimate their weight compared with men (OR 0.43, 95% CI 0.33 to 0.55 in Sami and OR 0.33, 95% CI 0.26 to 0.42 in non-Sami), higher BMI was protective against weight underestimation (OR 0.72, 95% CI 0.69 to 0.75 in Sami and OR 0.63, 95% CI 0.60 to 0.67 in non-Sami), slightly higher odds of weight underestimation were observed with increasing age in both ethnic groups (OR 1.03, 95% CI 1.01 to 1.05 in Sami and OR 1.02, 95% CI 1.00 to 1.03 in non-Sami), while higher education lowered the odds in non-Sami (OR 0.69, 95% CI 0.55 to 0.87). Weight underestimation was protectively associated with anxiety and depression in Sami men (OR 0.48, 95% CI 0.27 to 0.84) and in non-Sami women (OR 0.44, 95% CI 0.25 to 0.78) adjusted for age, BMI, education and marital status.ConclusionsIndependent of ethnicity, more men than women underestimated their weight. Underestimation of weight was protectively associated with anxiety and depression in Sami men and non-Sami women.

“…This might be a result of cultural and social value on ideal body weight by gender. Excess weight traditionally symbolizes high social class, power, and physical prowess, while preference for thinness exist among Korean women immersed in the stigma and bias faced by obesity [56]. Korean women with higher SES may have more resources to stay thin and more access to obtaining better knowledge regarding healthy weight control behaviors as compared to their lesser SES peers [57].…”

Obesity is a prominent global public health challenge as its prevalence has grown. Even though the increase in prevalence of obesity in Korea has been relatively low, it is expected to continually increase in the next several years, leading to social and economic burdens. This study aimed to assess socioeconomic inequalities in obesity among Korean adults. Using nationally representative survey datasets, the concentration index (CI) and decomposition of the CI were used to capture and quantify obesity-related inequalities from 1998 to 2015. The results suggested that pro-poor inequalities in obesity existed in Korea, indicating that obesity was more concentrated among individuals with lower income. In a gender-stratified model, obesity was more concentrated among women with lower income and men with higher income, showing that the trend and magnitude of inequalities in obesity each vary by gender. The decomposition approach revealed that, over the past 17 years, the main contributors to the existing inequalities were higher education and higher income levels. These findings suggest that comprehensive and multifaceted interventions at the local and national levels should be considered to address the identified income- and education-related barriers with respect to obesity among Korean adults.

“…Studies relating the association between psychological distress and weight perception are very limited. The directional association found in several studies had related weight perception to psychological distress and showed a stronger association between weight misperceptions and anxious/depressive symptoms [73][74][75]. The mechanisms that linked weight perception to psychological distress suggest that people engaging in selfevaluation had a poor body image and may often feel isolated or discriminated in social situations that in turn contribute to the feelings of distress and depression.…”

Background: In the time of confinement, a reduction of physical activities, unhealthy diet, sedentary behavior, and an increase in sitting time will contribute to weight change. During these stressful times, individuals might have a greater concern about their body image and weight. Therefore, the first objective of the current study is to evaluate the impact of confinement during the COVID-19 outbreak on weight variation. The second objective is to evaluate factors associated with weight perception among a sample of the Lebanese population.Method: A cross-sectional web-based online survey, carried out between 3 and 18 April, 2020, enrolled 407 participants. Due to the confinement situation, the height and weight of the participants were estimated by them themselves. The variation of declared BMI was calculated by taking away the weight estimated during the confinement from the weight estimated before the confinement. The perception of weight change was assessed using one dichotomized question (positive/negative). Results: No significant variation was found for the BMI before and during the confinement (p=0.40). A perceived weight change was found in 212 (52.1%) participants. Multivariable analysis showed that longer duration of confinement (Beta=-0.01), higher restraint (Beta=-0.21), higher physical activity (Beta=-0.006) and low income (Beta=-0.59) were significantly associated with a lower BMI variation. When taking perceived weight change as the dependent variable, the results showed that a higher fear of COVID-19 score (ORa=0.96) was significantly associated with lower positive weight change perception. However, higher confinement duration (ORa=1.07), higher anxiety (ORa=1.05) and higher eating concern (ORa=1.81) were significantly associated with greater weight change perception.Conclusion: Our main results indicate that no significant change in weight was detected before and during confinement. The fear of COVID -19 was not related to weight change; however, a negative association was found with weight perception. Also, longer duration of confinement were associated with a lower declared BMI variation and greater weight change perception. These results are a step forward to understand the long-term effects of confinement on physical and psychological health.
