Methods: Three groups were studied: overweight (n = 15), obese (n = 30) and control (n = 21) children and adolescents. To evaluate plasma lipid profile, total cholesterol, LDL-cholesterol, HDL-cholesterol and triglyceride levels were measured. Lipid peroxidation was determined by measuring malondialdehyde concentration. Data were analyzed using Studentís t test, Tukey test, ANOVA and Pearsonís correlation. Results: Altered levels of total and LDL-cholesterol were observed mainly in overweight or obese males. HDL-cholesterol was borderline in the overweight and obese groups of both sexes. Obese females had the highest levels of triglycerides. Increased plasma lipid peroxidation was observed mainly in obese males. Conclusion: In the present population, the greatest alterations in lipid profile were observed in obese and overweight males. Plasma lipid peroxidation was more evident in obese males and femalesAttribution-NonCommercial-NoDerivs 3.0 Brazilhttps://creativecommons.org/licenses/by/4.0/Análise de lipídeosPeroxidação de lipídeosObesidadePerfil lipídico e peroxidação de lipídeos no plasma em crianças e adolescentes com sobrepeso e obesidadePlasma lipid profile and lipid peroxidation in overweight or obese children and adolescentsarticlehttps://doi.org/10.2223/JPED.1129
