Abstract

This study examines metabolic patterns in a pediatric and teen student group from Itapetininga (SP), Brazil, focusing on insulin, glycemia, and C-reactive protein, incorporating body mass index, age, and race as explanatory variables. To improve robustness, influential observations were removed based on leverage diagnostics, and body mass index outliers were trimmed. Using log-linear regression models, results show that age is the main determinant of insulin levels, consistent with pubertal insulin resistance. Body mass index does not exhibit a strong independent effect but contributes modestly when interacting with age. Racial differences suggest heterogeneity in insulin dynamics. This data handling highlights the dominant role of developmental factors over adiposity in this population.
