Association between body weight misperception and dietary patterns in Brazilian adolescents: Cross-sectional study using ERICA data.

The association between body image and eating behaviors or weight control strategies has been demonstrated in the scientific literature, but there is a lack of evidence on the association between weight misperception and food consumption indicators in adolescents. This study aimed to evaluate the as...

This study aimed to evaluate the association between weight misperception and dietary patterns (DPs) in the Brazilian Study of Cardiovascular Risks in Adolescents (ERICA). It was a national school-based cross-sectional study conducted among students aged 12-17 years. Data were collected in the form of anthropometric measurements, responses in self-answered questionnaires, and 24-h dietary recall. The following variables were assessed: weight underestimation and overestimation (independent variables), which were defined as the presence of a disagreement between nutritional status and self-perceived weight; dietary patterns (dependent variables), defined by a posteriori method using principal component factor analysis; and individual and demographic variables (covariates). Data analysis was performed using the Poisson regression models method, stratified by sex. A total of 52,038 adolescents with normal weights were evaluated. The weight misperception prevalence was 34.0% (95% confidence interval [CI]: 33.0, 35.0). Three DPs were identified: "Traditional Brazilian," "Processed meat sandwiches and coffee," and "Ultra-processed and sweet foods." In girls, weight underestimation was directly associated with the "Traditional Brazilian" (1.24; 95% CI: 1.08, 1.43) and "Ultra-processed and sweet foods" DPs (1.29; 95% CI: 1.09, 1.54), and overestimation was inversely associated with all the DPs. In boys, a direct association between underestimation and the "Ultra-processed and sweet foods" DP (1.29; 95% CI: 1.10, 1.51) was found. Overestimation was inversely associated with the "Traditional Brazilian" DP (0.79; 95% CI: 0.63, 0.99). The inverse association between overestimation and the "Traditional Brazilian" DP, and the direct association between underestimation and the "Ultra-processed and sweet foods" DP indicated that weight misperception was related to unhealthy eating habits in Brazilian adolescents.Simoni Urbano da SilvaMariane de Almeida AlvesFrancisco de Assis Guedes de VasconcelosVivian Siqueira Santos GonçalvesLaura Augusta BarufaldiKenia Mara Baiocchi de CarvalhoPublic Library of Science (PLoS)articleMedicineRScienceQENPLoS ONE, Vol 16, Iss 9, p e0257603 (2021)
