The purposes of this study were to develop age- and sex-specific waist circumference reference data for Portuguese children and adolescents aged 10-18 years and to compare them with those from other countries. This was a school-based study performed in Portugal. A total of 22,003 children and adolescents aged 10-18 years were included in the study. Smoothed sex- and age-specific 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentile curves of waist circumference were estimated using Cole's lambda-mu-sigma method. Waist circumference values increased with age in both boys and girls, and boys had higher values than girls at every age and percentile. In both sexes, the Portuguese values in the 90th percentile were closer to the Bolivian values and considerably lower than those of the American children for all age groups.
The data presented provide information for abdominal risk assessment and clinical and lifestyle intervention; our results also provide useful baseline data information for the implementation of a surveillance system required to monitor trends and factors associated with abdominal obesity in children and adolescents.
目的 本研究旨在制定葡萄牙儿童和青少年（10-18 岁）的腰围参考值，并与其他国家进行比较。这是一项在葡萄牙开展的基于学校的研究。共纳入 22,003 名 10-18 岁的儿童和青少年。采用 Cole 的 lambda-mu-sigma 方法对腰围的性别和年龄特异性第 5、10、25、50、75、90 和 95 百分位曲线进行了平滑估计。男女儿童的腰围均随年龄增长而增加，且各年龄和百分位的男孩腰围值均高于女孩。在男女两性中，90 百分位的葡萄牙值与玻利维亚值更为接近，且明显低于所有年龄组的美国儿童值。
结论 本研究提供了腹部风险评估以及临床和生活方式干预的相关信息；本研究结果还为监测儿童和青少年腹部肥胖相关趋势和因素的监测系统的实施提供了有用的基线数据信息。
