目的 了解南京市3~6岁儿童腰围、臀围、腰臀比的现状及其与体格相关指标的关系,有针对性地制定措施,更好地促进儿童健康成长。方法 2015年采用分层随机整群抽样的方法调查南京市4 300名3~6岁儿童的腰围、臀围指标,计算腰臀比并对体格相关指标进行分析。结果 男、女童腰围、臀围均随着年龄的增加而增加,腰臀比随着年龄的增加而降低。平均腰围:男童49.4~54.5 cm,女童47.5~53.2 cm;平均臀围:男童53.3~62.5 cm,女童53.0~60.9 cm;平均腰臀比:男童0.87~0.96 cm,女童0.87~0.90 cm。儿童腰围、臀围及腰臀比在性别年龄组间差异有统计学。腰围和臀围分别与体重、身高及体重指数(BMI)呈正相关。腰臀比随着年龄的增加而降低,与身高、臀围呈负相关。结论 南京市3~6岁儿童腰围、臀围存在年龄和性别差异,腰围、臀围、腰臀比与其体重、身高及BMI有关。

Analysis on the correlation of waist circumference,hip circumference and anthropometric parameters in children aged 3-6 years in Nanjing

Objective To measure the levels of waist circumference, hip circumference and waist-to-hip ratio of children aged 3-6 years in Nanjing, and to analyze the correlation among these indexes and anthropometric parameters. Methods A total of 4 300 children aged 3-6 years were enrolled by using stratified random cluster sampling method, and the waist circumference and hip circumference were measured. Results Both the waist circumference and the hip circumference of boys and girls increased with the age growth, while the waist-hip ratio decreased with the age growth. The average waist circumference of boys was 49.4~54.5 cm and girls was 47.5~53.2 cm; The average hip circumference of boys was 53.3~62.5 cm and girls 53.0~60.9 cm; The average waist-hip ratio of boys was 0.87~0.96 cm and girls 0.87~0.90 cm.The waist circumference, hip circumference and waist-to-hip ratio of children were significantly different among different age and gender groups(P＜0.05).The waist circumference was positively correlated with body weight, height and BMI, so was hip circumference.The waist-to-hip ratio decreased with age, and was negatively correlated with height and hip circumference. Conclusions The waist circumference and hip circumference of children aged 3-6 years in Nanjing are different in different age and gender groups.Waist circumference, hip circumference and waist-to-hip ratio of children are related to body weight, height and BMI.
