摘要
objective: to determine fasting glycemia and insulinemia levels and the homa index in a group of children and adolescents with normal body mass index (bmi). methods: this was a cross-sectional study conducted at two public schools in ribeirˋo preto, sp, brazil. a total of 447 children and adolescents of both sexes, with normal bmi, aged 7 to 17.9 years and of average maturity for their age, underwent anthropometric measurements and provided personal data and a sample of venous blood so that glycemia, insulinemia and homa index could be determined. the results obtained for boys and girls were compared for each age range using the mann-whitney test. the results within each age band were then compared for boys and girls using the kruskal-wallis test. results: glycemia results varied from 7 to 8.9 years (p = 0.0005). fasting insulinemia varied significantly with age in both sexes (p %26lt; 0.001), with the highest values observed among children aged 13 to 14.9 years. homa indices varied significantly with age in both boys and girls (p %26lt; 0.001), with values that increased progressively up to the age band of 13 and 14.9 years. conclusions: these data demonstrate the necessity of establishing reference curves for these three indicators.
