Attitudes towards body weight dissatisfaction associated with adolescents’ perceived health and sleep (PeNSE 2015)

Abstract

This study aimed to investigate whether attitudes towards body weight dissatisfaction is associated with perceived health and impairments in sleep among a national population-based sample of Brazilian adolescents. This is a cross-sectional data from the 2015 National School-Based Health Survey (PeNSE). A total of 100.182 students (70.8% were between 14 to 15) in ninth-grade, enrolled in public and private schools were eligible for data analysis. Variables were measured using a questionnaire and binary logistic regression was used. There was association between attitudes towards body weight dissatisfaction and perceived health (not controlling weight = OR: 2.19, 95%CI: 2.00-2.40; trying to lose = OR: 1.90, 95%CI: 1.75-2.05; gain = OR: 2.22, 95%CI: 2.01-2.46; maintain = OR: 1.81, 95%CI: 1.54-2.14). Adolescents were also more likely to present impairments in sleep (not controlling weight = OR: 1.21, 95%CI: 1.11-1.32; trying to lose = OR: 1.16, 95%CI: 1.08-1.25; gain = OR: 1.43, 95%CI: 1.28-1.61; maintain = OR: 1.43, 95%CI: 1.22-2.68). Dissatisfaction is an additional concern in the daily life of adolescents, which is associated to depreciation of the quality of sleep and decrement of psychological well-being.

Association of body image with physical activity, sleep, meal and smoking in obese male

“…The majority of participants getting sufficient sleep seven hours or more, but it was observed that no significant association with body image. The result was not in line with our findings; previous studies found that bodyweight dissatisfaction has been associated with sleep impairment [60].…”

“…However, no significant association of meals with body image recognized. Our finding did not support previous study that suggested meal patterns and food consumption were associated with body dissatisfaction and overfat status among adolescents [60]. Some previous studies reflect that the number of meals taken a day was inversely related to obesity [61][62][63].…”

Network Associations Among Body Image, Lifestyle, Body Mass Index, and Quality of Life in Adolescents

“…Similarly, body image was the strongest significant predictor of HRQoL in children and adolescents (8). Previous findings have frequently demonstrated the relationship between body dissatisfaction with sleep impairment, sadness/loneliness, peer stress, depression, and low self-esteem (9,(37)(38)(39). The aforementioned problems would contribute to the impairment of adolescents' emotional and social functioning and explain how negative body image may result in poorer HRQoL in adolescents.…”

“…It is also documented that negative body image is associated with obesity-related lifestyle factors, including low levels of physical activity, unhealthy eating habits, and disordered eating (6,7). Previous studies documented the significant relationship between body image and healthrelated quality of life (HRQoL) (8,9). According to the existing evidence, lifestyle components, including physical activity and eating habits, have been significantly associated with obesity and HRQoL (10)(11)(12).…”
