Purpose To verify the influence of overweight and alteration in the perception of the corporal image during the triage of eating disorders. Method A food disorder triage was performed in adolescents with 10 to 19 years of age using the Eating Attitudes Test (EAT-26), Children's Eating Attitudes Test (ChEAT), and Bulimic Investigatory Test Edinburgh (BITE), as well as a nutritional status evaluation. The perception of body image was evaluated in a subsample of adolescents with 10 to 14 years of age, using the Brazilian Silhouette Scale. The project was approved by the Human Research Ethics Committee of the Federal University of Viçosa, Minas Gerais, Brazil. Results The prevalence of eating disorder triage was 11.4% (n = 242) for the 2,123 adolescents evaluated. Overweight was present in 21.1% (n = 447) of the students, being more prevalent in the early adolescence phase, which presented levels of distortion of 56.9% (n = 740) and dissatisfaction of 79.3% (n = 1031). Body dissatisfaction was considered as a risk factor, increasing by more than 13 times the chance of TA screening. Conclusion Overweight was correlated with the ED triage and body dissatisfaction was considered as a risk factor, increasing the chances of these disorders by more than 13 times.

ObjectiveTo evaluate agreement of the body adiposity index (BAI) and paediatric body adiposity index (BAIp) in estimating body fat compared with dual-energy X-ray absorptiometry (DXA) and to propose cut-off points for these indices to classify excess adiposity in Brazilian children and adolescents.DesignCross-sectional study. Measures of weight, height, hip circumference, BMI and body fat percentage (%BF) assessed by DXA were taken, and BAI and BAIp were calculated. The Bland–Altman plot was used to estimate agreement between the methods, and the receiver-operating characteristic curve to determine the cut-off points for BAI and BAIp per age and sex in comparison with DXA.SettingViçosa, Minas Gerais, Brazil.SubjectsChildren and adolescents aged 8–19 years (n 1049).ResultsOf the children and adolescents, 52·4 % were girls. BAI and BAIp had satisfactory performance by the receiver-operating characteristic curve, except for the 18–19 years age group, whose BAIp had better predictive capacity than BAI. The agreement analysis showed that BAI overestimated %BF by 2·64 %, on average, using DXA; while BAIp underestimated %BF by 3·37 %.ConclusionsBAI and BAIp showed low agreement with the body fat obtained by DXA, requiring caution when interpreting body composition data in children and adolescents.

An association was found between younger age at menarche and the development of the PCOS in adolescents.

Objetivo: avaliar comportamento alimentar de risco para o desenvolvimento de transtorno alimentar em acadêmicas de uma instituição do município de Viçosa-MG. Métodos: estudo transversal realizado com 104 universitárias com idade igual ou superior a 18 anos, matriculadas no primeiro período. Foram coletados dados deidade, área de conhecimento, curso, antropometria e composição corporal e aplicado o Teste de Atitudes Alimentares (EAT-26). Além da realização da análise descritiva dos dados, utilizou-se o Teste Kolmogorov-Smirnov, o Teste U de Mann- Whitney, o Teste Qui-Quadrado e o Coeficiente de Spearman. Este estudo foi aprovado pelo Comitê de Ética da Universidade Federal de Viçosa e todas as estudantes assinaram o Termo de Consentimento. Resultados: A prevalência de triagem positiva para anorexia nervosa (EAT+) foi de 21,2% (n=22). Verificou-se que 76% (n=79) das participantes foram classificadas como eutróficas pelo índice de Massa Corporal (IMC). Houve associação entre o risco cardiometabólico (pela relação cintura-estatura – RCE) e EAT+ (p=0,023). Observou-se que o grupo EAT+ se difere do EAT- para IMC (p=0,005) e perímetro da cintura (p=0,022); e o grupo Nutrição se difere dos outros para IMC (p=0,010) e RCE (p=0,013). Não se obteve diferença para a prevalência de EAT+ nas diferentes áreas. Conclusão: A elevada prevalência de EAT+ observada nas universitárias é fator preocupante para a saúde física e psíquica, necessitando de políticas de saúde para prevenção de transtornos alimentares de forma efetiva.

The aim of this study was to analyze body fat anthropometric equations and electrical bioimpedance analysis (BIA) in the prediction of cardiovascular risk factors in eutrophic and overweight adolescents. 210 adolescents were divided into eutrophic group (G1) and overweight group (G2). The percentage of body fat (% BF) was estimated using 10 body fat anthropometric equations and 2 BIA. We measured lipid profiles, uric acid, insulin, fasting glucose, homeostasis model assessment-insulin resistance (HOMA-IR), and blood pressure. We found that 76.7% of the adolescents exhibited inadequacy of at least one biochemical parameter or clinical cardiovascular risk. Higher values of triglycerides (TG) (P = 0.001), insulin, and HOMA-IR (P < 0.001) were observed in the G2 adolescents. In multivariate linear regression analysis, the % BF from equation (5) was associated with TG, diastolic blood pressure, and insulin in G1. Among the G2 adolescents, the % BF estimated by (5) and (9) was associated with LDL, TG, insulin, and the HOMA-IR. Body fat anthropometric equations were associated with cardiovascular risk factors and should be used to assess the nutritional status of adolescents. In this study, equation (5) was associated with a higher number of cardiovascular risk factors independent of the nutritional status of adolescents.
