Introduction: During the fetal period and early infancy, the person is more influenced by environmental factors that may have permanent health consequences, such as obesity. Most of the available evidences evaluate the association of environmental factors with body mass index, despite the known limitations of this evaluation. Objective: this paper objective is to analyze the associations between fat percentage and the risk factors from the prenatal period. Methods: It was studied 225 students aged 5-18 years from Porto Alegre and Canela using verbal communication. The participants and their officials answered questionnaires about demography, socioeconomic data, related to stress factors and the measurement of the percentage of fat through bioimpedance analysis. The associations between fat percentage and stress factors (inadequate gestational weight gain, maternal smoking, low birth weight, cesarean section, gestational birth age, duration of breastfeeding, sleep time in the first year of life, diagnosis of chronic diseases and use of corticoids in the first year of life and in the last 12 months) were evaluated using the unique variation and multivariable linear Generalized model. Results: Of the 225 subjects enrolled, 94 (42%) were male and the average age was 9 ± 3 years. The use of corticosteroids during the first year of life and in the last twelve months were the only factors that had a significant association with the fat percentage in the unique variation regression model (OR 1.29, 95% CI 1.01 to 1.49; P = 0.003; OR 1.30, 95% CI 1.09 -1.54; P = 0.002), respectively. In the multivariate model, only the use of corticosteroids in the last year remained significant (OR 2.98; 27.01 -7.00; P = 0.012). Conclusion: The use of corticosteroids is associated with excess fat percentage in children and adolescents.
