Inter-relação entre antropometria, composição corporal e perfil bioquímico de adolescentes com excesso de peso

Abstract

Introduction: Obese adolescents are likely to remain overweight into adulthood and are likely to remain overweight into adulthood and to develop metabolic disorders in the future. Objective: to verify the relation between variables such as body composition, anthropometry and biochemical profile of overweight or obese adolescents. Methodology: This is a cross sectional and quantitative study, involving 132 adolescents aged 12 to 17 years, between 2017 and 2020. The variables analyzed were: age, height, body mass index (BMI); lean mass (LM); fat-free mass (FFM); body fat mass (BFM); skeletal muscle (SM) mass; percentage of body fat (% BF); waist-hip ratio (WHR); lean mass index (LMI); fat mass index (FMI); fat-lean mass ratio (FLMR); glucose (GLU), total cholesterol (CT); high-density lipoproteins (HDL c); low density lipoproteins (LDL-c); triglycerides (TG); alanine aminotransferase (ALT) and aspartate aminotransferase (AST). After confirming normality, the unpaired t test was used to compare differences between genders, in addition to Pearson's correlation and multiple linear regression, assuming p <0.05. Results: Both the general group (male and female) and the female and male parallel group between BMI and RGM (r = 0.69; r = 0.74; r = 0.69); BMI and FFM (r = 0.49; r = 0.67; r = 0.44); BMI and SM (r = 0.50; r = 0.68; r = 0.44) and BMI and %BF (r = 0.47; r = 0.54; r = 0.40) respectively, all p <0.01. Only in the general group was found correlation between BMI and HDL-c (r = -0.18; p < 0.05). Once the findings of the present study are known, it is concluded that anthropometric, body composition and biochemical indices above the cutoff points proposed in the literature can compromise the health and quality of life of the investigated adolescents.
