目的了解绍兴市7岁以下儿童单纯性肥胖的流行现状及影响因素。方法按分层随机整群抽样的原则,全市共调查0~2岁儿童7985人,3~6岁儿童17640人,以WHO身高标准体重为肥胖的判断标准,描述分析不同月龄、性别超重与肥胖的检出率,并按病例对照设计方法,用多因素Logistic回归分析,筛选肥胖相关的危险因素。结果肥胖总检出率4.23%,超重总检出率10.79%;其中0~2岁儿童肥胖、超重检出率分别为2.64%和9.83%,3~6岁儿童肥胖、超重检出率分别为4.92%和11.05%,3~6岁儿童肥胖、超重检出率均明显高于0~2岁儿童(P均<0.05)。男童肥胖检出率明显高于女童(P<0.05)。肥胖影响因素主要为高出生体重,出生孕周≥42周,家庭人口数>3,父母高BMI以及家长认为孩子体重偏瘦、食欲好、进食速度快和常吃零食。结论绍兴市7岁以下儿童肥胖、超重检出率处在较高水平,应针对肥胖影响因素进行早期干预,减少肥胖对儿童造成的近期和远期影响。
Objective To understand the prevalence and influencing factors of simple obesity in children under 7 years of age in Shaoxing. Methods According to the principle of stratified random cluster sampling, the city surveyed 7985 children 0 to 2 years old and 17640 children aged 3 to 6 years old. According to the WHO standard height and weight criteria for obesity, Obesity detection rate, and according to the case-control design method, using multivariate Logistic regression analysis, screening for obesity-related risk factors. Results The total detection rate of obesity was 4.23%, and the total detection rate of overweight was 10.79%. The detection rates of obesity and overweight in children aged 0 ~ 2 years were 2.64% and 9.83% respectively. The detection rates of obesity and overweight in children aged 3 ~ 6 were 4.92% and 11.05% respectively. The detection rates of obesity and overweight in children aged 3 ~ 6 years were significantly higher than those in children aged 0 ~ 2 years (all P <0.05). The prevalence of obesity in boys was significantly higher than that in girls (P <0.05). The main influencing factors of obesity are high birth weight, gestational age≥42 weeks, family population> 3, parents with high BMI and parents think their children are underweight, good appetite, fast eating and eating snacks.
