甘肃省农村0～7岁儿童超重、肥胖影响因素调查研究

目的了解甘肃省农村地区7岁以下儿童超重、肥胖的现状及其影响因素。方法采用分层随机整群抽样方法抽取甘肃省四市县农村地区7岁以下9390名健康儿童,采用体质指数(BMI)进行超重和肥胖的筛查;所有资料用Epidata 3.0软件、采用双份录入法建立数据库,并用Excel、SPSS 11.0软件对数据进行统计分析。结果甘肃省农村地区7岁以下儿童超重检出率为8.2%(男8.7%,女7.8%),肥胖检出率为6.1%(男6.4%,女5.8%);儿童出生体重≥4000g、散居的生活方式是超重(OR=2.317,95%CI为1.640～3.275;OR=3.381,95%CI为2.324～4.918)和肥胖(OR=1.878,95%CI为1.225～2.881;OR=3.243,95%CI为2.046～5.140)的独立的危险因素。结论 9月龄～2岁农村儿童发生超重和肥胖的风险较高,应该作为重点干预人群;减少巨大儿的出生和散居的生活方式有助于减少儿童超重和肥胖的发生。

Surveys on the status and associated factors of overweight and obesity of rural children under 7 year-old in Gansu Province

Objective To understand the status and associated factors of overweight and obesity of rural children under 7 year-old in Gansu province.Methods A total of 9390 rural children under 7 year-old and their mothers in 4 counties in Gansu province were selected by stratified random cluster sampling method and screened for overweight or obesity by BMI.All data were input by using a double entry method with EPI data 3.0 software and analyzed statistically by Excel /SPSS 10.0 software.Results The detection rate of overweight in rural children under 7 in Gansu province was 8.2%(male 8.7%,female 7.9%),the detection rate of obesity was 6.1%(male 6.4%,female 5.8%).The independent risk factors for overweight and obesity were birth weight ≥ 4000g and living in scattered lifestyle.Conclusion The risks of overweight and obesity in rural children are rather high,more attention should be paid to children aged from 9 month to 2 years.Reducing the rate of birth weight ≥ 4000g and scattered lifestyle in children can make some contribution to the prevention of obesity and overweight.
