Abstract: 【Objective】 To investigate the epidemic situations of obesity of infants from 0 month to 2 years old and its influencing factors in Shaoxing. 【Methods】 Cluster-random sampling was used to investigate 7 985 infants in all.Overweight and obesity were defined by the WHO weight for height standards. 【Results】 The rate of obesity among the infants was 2.64%,and the boys was 2.64% while the girls was 2.24%.The rate of overweight was 9.83%,and 10.50% for boys,9.06% for girls.There were significant differences in the prevalence between boys and girls (χ²_obesity=4.424,χ²_overweight=4.687,P<0.05).The detectable rate of obesity among the infants below 1 years of age showed a decreasing tendency with age.However,the rate showed a rising tendency among the infants who were older than 18 months.There were significant differences in the prevalence in different age groups (χ²_obesity=173.627,χ²_overweight=161.542,P<0.01).Obesity of children was correlated with high birth weight,the parent's BMI,big family and the parent's attitude towards obesity. 【Conclusions】 The detection rate of overweight and obesity is in higher level.The main influencing factors include high birth weight,the parental BMI,big family and the parental attitude towards obesity.

摘要： 【目的】 了解绍兴市0~2岁婴幼儿超重肥胖流行现状及影响因素,为早期干预提供理论依据。 【方法】 按照随机整群抽样的方法,调查7 985名婴幼儿,以WHO身高标准体重为肥胖的判断标准。 【结果】 0~2岁婴幼儿总的肥胖检出率为2.64%,男童2.99%,女童 2.24%,总的超重检出率为9.83%,男童10.50%,女童9.06%,男女童之间肥胖超重检出率差异均有统计学意义(χ²_肥胖=4.424,χ²_超重=4.687,P均<0.05)。1岁以内婴儿年龄越小肥胖检出率越高,18月以后随年龄增加肥胖检出率呈上升趋势,各年龄组之间的超重及肥胖检出率差异有统计学意义(χ²_肥胖=173.627,χ²_超重=161.542,P值均<0.01)。肥胖影响因素有高出生体重、家庭人口多、父母BMI、家长对子女肥胖的态度。 【结论】 绍兴市婴幼儿肥胖检出率处于较高水平,高出生体重、家庭人口多、父母BMI、家长对子女肥胖的态度是本次调查婴幼儿肥胖的影响因素。
