| 目的 了解新疆维吾尔自治区(新疆)汉、维吾尔(维)族3～9岁儿童腰围(WC)和腰围身高比(WHtR)分布特征,探讨其作为儿童肥胖筛查指标的价值。方法 采用分层整群随机抽样方法,于2014年4月抽取新疆四地区幼儿园和小学一、二年级汉、维族儿童,测量身高、体重及WC;以WC的性别年龄别第80百分位值(P80)以及WHtR≥0.48为参考值,在BMI正常儿童中筛查可能患有腹型肥胖的儿童。结果 共测量3～9岁儿童4 024名,其中汉族2 461名,维族1 563名;汉、维族儿童WC、WHtR P50和P80数值相近,P95相差明显;BMI正常的汉、维族儿童中存在WC≥P80或WHtR≥0.48的儿童:BMI正常的4～岁汉族男童中,WC≥P80的比例为8.0%,4～岁维族女童中该比例为16.3%; <7岁儿童中WHtR≥0.48的比例在10%以上,随着年龄段增长该比例逐渐下降。结论 新疆汉、维族儿童WC和WHtR分布特征相似,WC和WHtR可用于从BMI正常儿童中筛查超重/肥胖儿童,建议在学龄前儿童超重/肥胖筛查时与BMI联合使用。 |

| Objective To understand the distributions of waist circumference and waist-to- height ratio (WHtR) in Han and Uygur ethnic children aged 3-9 years in Xinjiang Uygur Autonomous Region (Xinjiang) and discuss their values in obesity screening in children. Methods Stratified cluster random sampling was conducted to select Han and Uygur ethnic children from kindergartens and primary schools in four areas of Xinjiang in April 2014. The children's standing height, body weight and waist circumference were measured by trained investigators according to standard protocol. WC≥P80 and WHtR≥0.48 were used as the cutoff value for abdominal obesity screening in children with normal BMI. The association between overweight/obese prevalence rate and obesity related indicators, such as BMI, WC, WHtR, were analyzed. Results A total of 4 024 Han and Uygur ethnic children were investigated, in which 2 461 were in Han ethnic group, 1 563 were in Uygur ethnic group. The WC and WHtR at P50 and P80 were similar in two groups, but WC and WHtR at P50 were differed significantly. In both Han and Uygur ethnic groups, there were some children with WC≥P80 or WHtR≥0.48, although they had normal BMI. This proportion decreased with age. Conclusions The WC and WHtR are similar in Han and Uygur ethnic children aged 3-9 years. WC and WHtR have values in obesity screening for children with normal BMI which suggested to use it as the supplementation of BMI in obesity screening in preschool aged children. |
