The study aimed to analyze the association between pubertal development stages and adiposity in children and adolescents.
Cross-sectional study conducted in 2007 in Florianópolis, Brazil, with 2339 schoolchildren 32 aged 8 to 14 years old (1107 males). The outcome (adiposity) was evaluated using Z score and 33 percentilee values > = 85 of four skinfolds (triceps, subscapular, suprailiac and calf) and waist 34 circumference. Total body adiposity (Z score of the sum of skinfolds), central adiposity (Z score 35 of waist circumference) and peripheral adiposity (Z scores of triceps and calf skinfolds) were 36 estimated. Pubertal development stages was self-assessed according to Tanner stages of development. Thirty-seven Children and adolescents were classified according to tertiles of age for each pubertal development stages 38 stage - early, normal and late. Statistical analysis was performed using univariate and 39 multivariate Poisson regression models.
Children and adolescent from both sexes with early pubertal development stages presented higher prevalence of central adiposity (waist circumference), with adjusted prevalence ratio (CI 95%) of 2.21 (1.12; 4.35) for males and 2.18 (1.04; 4.57) for females (reference group: normal pubertal development stages). Among females, there was a reduction in the prevalence of excess adiposity with decreased occurrence of early pubertal development stages. There was a strong relationship between adiposity and pubertal development stages.
Excess adiposity was higher in both sexes for those with early pubertal development stages.
本研究旨在分析儿童和青少年青春期发育阶段与肥胖的关系。
这是 2007 年在巴西弗洛里亚诺波利斯进行的一项横断面研究，共有 2339 名 8 至 14 岁的学童（男 1107 人）参与。使用四个皮褶（三头肌、肩胛下、髂嵴上和小腿）和腰围的 Z 分数和 > = 85 的 33%百分位数值评估结果（肥胖）。还估计了总身体肥胖（皮褶总和的 Z 分数）、中心肥胖（腰围的 Z 分数）和外周肥胖（三头肌和小腿皮褶的 Z 分数）。青春期发育阶段根据发育的 Tanner 阶段进行自我评估。根据每个青春期发育阶段的年龄三分位数（早期、正常和晚期）对儿童和青少年进行分类。使用单变量和多变量 Poisson 回归模型进行统计分析。
青春期发育较早的男童和女童中央肥胖（腰围）的患病率较高，调整后的患病率比（95%CI）分别为 2.21（1.12；4.35）和 2.18（1.04；4.57）（参考组：正常青春期发育阶段）。对于女性，随着青春期发育早期阶段的发生减少，超重肥胖的患病率降低。肥胖与青春期发育阶段之间存在很强的关系。
对于青春期发育较早的男童和女童，肥胖程度较高。
