RESUMO:

Introduction: Concern about body and body shape, as well as the occurrence of dissatisfaction with body image has increased in adolescence, thus, the occurrence of sedentary lifestyle and obesity stands out in this scenario, which can increase frustration with the body and generate harmful effects in the physical and mental health of young people, making it necessary to expand the understanding of this theme. Objective: To evaluate the association of anthropometric status, level of physical activity, and sedentary behavior with negative body image in public schools in Salvador. Methods: This is a cross-sectional study nested in the cohort entitled “School and family environment and cardiovascular risk: a prospective approach”. The place and the study sample comprise, respectively, six state public schools in Salvador and 465 adolescents of both sexes aged between 10 and 17 years enrolled in these teaching units. Body image was assessed for its perceptual dimension (divergence in body size = difference between actual and actual BMI) and attitudinal (body dissatisfaction = difference between desired and current body mass index (BMI) using the silhouette scale. To identify anthropometric status, BMI / age and sex in percentile recommended by WHO and waist circumference in the 90th percentile of the sample itself were adopted. A Physical Activity Questionnaire for Adolescents was adopted to identify the level of physical activity and TV time was used to assess sedentary behavior using the Global School-based Student Health Survey reference. In addition, demographic information (gender, age, and economic status) was obtained. The descriptive analysis of the data was performed using the proportion for categorical variables. The magnitude of the association between anthropometric status, physical activity, sedentary behavior, and dissatisfaction with body image was expressed as a Chance Ratio (Politomic Logistic Regression) and respective 95% confidence intervals (95% CI). The AIC assessed the fit of the final model. Statistical significance of 5% was adopted. The data were analyzed using the STATA statistical package, version 16.0. Results: The prevalence of Body Image Dissatisfaction was 78.3%, of Body Image Distortion 81.3%. Body dissatisfaction was positively associated with overweight and inadequate WC, but there was no association with lifestyle variables. Conclusion: It is concluded that anthropometric status is an important indicator for IIC and DTC. Public policies aimed at the school environment become essential, aiming at strategies and plans for a greater corporal acceptance of the adolescent.
