Abstract

OBJECTIVE

The purpose of this study was to examine the relationship between sexual maturation (SM), and the prevalence of overweight among boys and girls.

SUBJECTS AND METHODS

The sample of this cross-sectional study included 819 children and adolescents (382 boys and 437 girls), aged 10-15 years old randomly selected from 30 schools in the Porto region. Anthropometrical measurements (body height, weight and skinfolds thickness) were determined by standard anthropometrical methods. Body mass index (BMI) was calculated from the ratio weight/height(2) (kg/m(2)). The sum of tricipital and subscapular skinfolds (TriSub) was also used. Physicians collected data on Tanner stages during physical examination. Subjects were grouped using the quartiles of the decimal age adjusted for Tanner stages of SM and gender.

RESULTS

The prevalence of overweight was higher in early maturing boys (30.5%) and early maturing girls (32.7%). The late maturers presented a lower prevalence (p < 0.05) of overweight (20.3% boys and 18.3% girls). Logistic regression analysis illustrates that early maturing is associated with an increased risk for overweight or obesity for boys (OR: 1.87 and 95% CI: 0.99-3.50) and girls (OR: 2.14 and 95% CI: 1.12-4.07), when compared with the boys and girls of the fourth quartile (p < 0.05).

CONCLUSIONS

We conclude that there is an association between early SM and the prevalence of overweight in both genders.

摘要

目的

本研究旨在探讨性成熟（SM）与男孩和女孩超重患病率之间的关系。

对象与方法

这项横断面研究的样本包括从波尔图地区30所学校随机选取的819名儿童和青少年（382名男孩和437名女孩），年龄在10至15岁之间。通过标准人体测量方法测定人体测量指标（身高、体重和皮褶厚度）。根据体重/身高²（kg/m²）的比值计算体重指数（BMI）。还使用了肱三头肌和肩胛下皮褶厚度之和（TriSub）。医生在体格检查时收集有关坦纳分期的数据。根据性成熟和性别的坦纳分期调整后的十进制年龄四分位数对受试者进行分组。

结果

早熟男孩的超重患病率较高（30.5%），早熟女孩的超重患病率也较高（32.7%）。晚熟者的超重患病率较低（p<0.05）（男孩为20.3%，女孩为18.3%）。逻辑回归分析表明，与第四四分位数的男孩和女孩相比，早熟与男孩（比值比：1.87，95%置信区间：0.99 - 3.50）和女孩（比值比：2.14，95%置信区间：1.12 - 4.07）超重或肥胖风险增加相关（p<0.05）。
