The objective of the present study was to estimate the prevalence of overweight and abdominal obesity in schoolchildren according to anthropometric parameters and sexual maturation. A cross-sectional study was performed in 1,405 children of both genders aged 10-14 years, living in Recife, Pernambuco State, Brazil, in 2007. Body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WHtR) were assessed. Sexual maturation was self-assessed. Early sexual maturation was defined as the chronological age below the median age for the referred stage. Prevalence of overweight was 20.4% (95%CI: 18.3-22.6), and abdominal obesity was 14.9% (95%CI: 13.1-16.9) and 12.6% (95%CI: 10.9-14.4) according to WC and WHtR, respectively. There was a strong positive correlation among BMI, WC, and WHtR (rho ≅ 0.8; p < 0.001). In both genders, the prevalence of overweight and abdominal obesity was higher in the final stages of sexual maturation (p < 0.05). The high prevalence of overweight requires urgent preventive measures and control. Therefore, the inclusion of sexual maturation for the assessment of nutritional status is recommended.
本研究的目的是根据人体测量参数和性成熟情况估计学龄儿童超重和腹型肥胖的患病率。2007年，在巴西伯南布哥州累西腓市对1405名年龄在10 - 14岁的男女儿童进行了一项横断面研究。评估了体重指数（BMI）、腰围（WC）和腰高比（WHtR）。性成熟情况由儿童自我评估。性早熟定义为实际年龄低于相应阶段的中位数年龄。根据腰围和腰高比，超重患病率分别为20.4%（95%CI：18.3 - 22.6），腹型肥胖患病率分别为14.9%（95%CI：13.1 - 16.9）和12.6%（95%CI：10.9 - 14.4）。体重指数、腰围和腰高比之间存在很强的正相关性（rho≅0.8；p < 0.001）。在两个性别中，性成熟后期超重和腹型肥胖的患病率更高（p < 0.05）。超重的高患病率需要紧急的预防措施和控制。因此，建议将性成熟纳入营养状况评估。
