Prevalence of overweight in adolescents from a Southern Brazilian city according to different anthropometric indexes

Objectives Regular physical activity and adequate food are part of a healthy lifestyle for the maintenance of physical and metabolic health. To verify the moderating role of physical activity (PA) in the relationship between dietary patterns and body adiposity in adolescents, according to somatic maturation. Methods Study with cross-sectional design, sample of 336 adolescents of both sexes, aged between 11 and 17 years. Body mass, height, and waist circumference (WC) were evaluated. Body mass index (BMI), BMI z-score (BMI-z), waist-to-height ratio (WHtR), and somatic maturation by peak height velocity (PHV) were calculated. The level of PA was measured by the International Physical Activity Questionnaire and dietary pattern by the Food Frequency Questionnaire ELSA – Brazil (short version). Moderation analyzes were tested using multiple linear regression models, by PROCESS macro for SPSS. Results An inverse interaction of PA was observed in the relationship between food consumption factor 5 (ultra-processed foods category) and WC in boys categorized as pre-pubertal and pubertal PHV (β=−5.344; CI95 % −10.108 −0.580; p=0.028). For girls, no interaction was observed in any of the models analyzed. Conclusions It was observed that the level of PA can influence food choices in prepubertal and pubertal boys, since the active boys showed better dietary pattern and lower central adiposity. Therefore, the findings reinforce the need to encourage the regular practice of physical activities from an early age, mainly aimed at preventing obesity in children and adolescents.

Objective: To evaluate the agreement between body mass index (BMI) parameters applied to children aged six to ten years in the city of Montes Claros (MG), Brazil with national and international criteria, also calculating their sensitivity and specificity regarding excess weight screening. Methods: A sample comprising 4151 children aged six to ten years was assessed, with height and body mass determined for BMI calculation. The obtained values were classified according to cutoff points established by the World Health Organization (WHO), International Obesity Task Force (IOTF), Centers for Disease Control and Prevention (CDC), Conde & Monteiro, and a recent local proposal. The agreement index between the mentioned criteria was calculated and thereafter the sensitivity and specificity. Results: The local proposal was proven to be highly consistent in most combinations, especially concerning the excess weight criteria of the World Health Organization (WHO) (k=0.895). Regarding excess weight, the local proposal presented sensitivity and specificity values of 0.8680 and 0.9956, respectively, indicating high BMI discrimination power. Conclusions: The locally applied BMI parameters for children aged six to ten years represent a valid, highly viable and practical proposal for excess weight screening in this population group, improving professional decision-making in their follow-up.
