ABSTRACT Objective To evaluate the association between children and adolescents’ body composition with family income. Methods Cross-sectional study, participants 5 19 years were included. A standardized questionnaire assessed socioeconomic variables. The outcome variables z-score of Body Mass Index bioimpedance parameters (skeletal muscle mass, fat-free fat percentage) predictor (age, sex, race, place residence, father’s education, birth weight breastfeeding) analyzed using quantile regression model data from 50th percentile are presented. tests bidirectional differences considered significant p<0.05. Results Among 529 included, 284 (53.6%) female mean age was 11.41±3.9 years. only that did not show sexes (p=0.158). In crude model, lower income associated skeletal mass (Difference=-7.70; 95% CI -9.32 to -5.89), p<0.001), (Difference= -13.40; -16.40 -10.39, p<0.001) lowest percentage -5.01, -9.91 -0.11, p=0.027). BMI Conclusion Family is directly percentage, in adolescents.
