“…However, the hypothesis that body image perception could have a more significant impact on extreme behaviors is reinforced when considering the relationship between body image distortion and such practices. For example, normal weight adolescents who overestimate or underestimate their nutritional status have higher chances of fasting, vomiting, or using laxatives and medicines without a medical prescription, when compared to those who consider their weight adequate 21,22 .…”

Introduction: This study aimed to analyze the association between nutritional status, body image perception, and extreme weight control behaviors among adolescents. Methods: This is an analytical cross-sectional study conducted in Brazil based on the National Adolescent Student Health Survey (Pesquisa Nacional de Saúde do Escolar -PeNSE) of 2015, with adolescents aged 13 to 17 years. Nutritional status and body image perception were the independent variables. The two dependent variables were vomiting or laxative use and use of medicines and other formulas for weight control in the 30 days prior to data collection. We used Poisson regression models for association, with demographic variables for control. Results: 7.4% of adolescents (95%CI 6.7 -8.2) reported vomiting or using laxatives, with no difference between genders. The prevalence of use of medicines and formulas was higher among boys (7.8%; 95%CI 6.6 -8.9). The association between nutritional status and extreme behaviors was not significant. However, the prevalence of vomiting or laxative use for adolescents who considered themselves very fat was 2.3 (95%CI 1.1 -4.7) times higher for boys and 5.3 (95%CI 3.3 -8.6) times higher for girls, while the use of medicines and formulas was 4.0 (95%CI 2.3 -7.1) times higher for girls who considered themselves very fat. Conclusion: Body image perception seems to have a greater influence on extreme behaviors than nutritional status. Strategies involving health services and schools have great potential to impact the self-esteem and health of students positively.

“…Paradoxically, following the augmented prevalence of obesity, there is mediatic and social pressure for the adoption of a progressively thin and muscular body appearance [ 9 ]. In this context, self-perception of weight can be easily affected, potentially leading to psychosocial stress and, consequently, reducing self-esteem while increasing anxiety, depression, and nutritional problems [ 10 ].…”

Systems Nutrology of Adolescents with Divergence between Measured and Perceived Weight Uncovers a Distinctive Profile Defined by Inverse Relationships of Food Consumption

Changes in food consumption, physical inactivity, and other lifestyle habits are potential causes of the obesity epidemic. Paradoxically, the media promotes idealization of a leaner body appearance. Under these circumstances, self-perception of weight by adolescents may be affected. Here, we performed a cross-sectional study, between June and December 2009, to evaluate the interaction between anthropometric status, perceived body weight, and food consumption profiles in 1496 adolescents from public schools in Salvador, Brazil. Data on socio-epidemiological information, anthropometric status, and dietary patterns were analyzed using multidimensional statistical approaches adapted from systems biology. There were dissimilarities between anthropometric status and perception of body weight related to sex. Four dietary patterns were identified based on the food intake profile in the study participants. The distinct dietary patterns were not influenced by divergence between measured and perceived weight. Moreover, network analysis revealed that overestimation of body weight was characterized by a selectivity in ingestion of food groups that resulted in appearance of inverse correlations of consumption. Thus, misperception of body weight is associated with inverse correlations of consumption of certain food groups. These findings may aid individualized nutritional interventions in adolescents who overestimate body weight.

“…We performed a cross-sectional study in the city of Salvador, state of Bahia, the third largest city of Brazil, with adolescents from state public schools, as part of a larger project performed between June and December 2009 that assessed psychosocial factors as elements that affect health, nutrition and cognitive development [10]. Students with age between 11 and 17 years old, of both sexes who regularly attended the school and had parental/guardian approval were eligible to participate.…”

Multidimensional Analysis of Food Consumption Reveals a Unique Dietary Profile Associated with Overweight and Obesity in Adolescents

et al. 2019

There is a significant increase in overweight and obesity in adolescents worldwide. Here, we performed a cross-sectional study to examine the potential association between food consumption profiles and overweight in a large number of adolescents from Brazil. Sampling by clusters and conglomerates was carried out in students of public schools in Salvador, Brazil, between June and December 2009 and 1496 adolescents were evaluated. Data on socio-epidemiological data, anthropometric status and food consumption were captured. Multivariate analyses, such as hierarchical clustering and correlation networks, were used to perform a detailed description of food consumption profiles. There were differences in age and anthropometric status related to sex. Four clusters of food groups were identified based on the intake profile in the study population. No disparities in food intake were observed in individuals stratified by sex or anthropometric status. Furthermore, network analysis revealed that overweight or obesity were hallmarked by a selectivity in the ingestion of food groups that resulted in the appearance of inverse correlations of consumption, which was not present in eutrophic adolescents. Thus, overweight and obesity are associated with preferential choices of ingestion of specific food groups, which result in the appearance of inverse correlations of consumption. Such knowledge may serve as basis for future targeted nutritional interventions in adolescents.

Risk Factors for Adopting Extreme Weight-Control Behaviors among Public School Adolescents in Salvador, Brazil: A Case-Control Study

Abstract: The results of this study suggest that among adolescents, overweight, body image dissatisfaction, and restrictive diet are important risk factors to adoption of extreme weight-control behaviors.
