父母体质指数与学龄前儿童超重肥胖的关联研究

Association of parental body mass index with overweight and obesity in preschool children

目的掌握城市学龄前儿童超重、肥胖的流行现状,探究父母体质指数与学龄前儿童超重肥胖的关系。方法选取江苏省南京市、山东省淄博市4所幼儿园的2037名学龄前儿童作为研究对象,采用logistic模型分析父母体质指数与儿童超重肥胖的关系。结果所调查学龄前儿童超重肥胖率为24.30%,超重率为13.16%(男14.54%,女11.66%),肥胖率为11.14%(男12.28%,女9.92%)。校正地区、儿童性别、年龄等因素后,父母超重肥胖是儿童超重肥胖的风险因素。父母均超重肥胖、仅母亲超重肥胖、仅父亲超重肥胖的儿童发生超重肥胖的风险,分别是父母均正常或偏瘦的3.00(95%CI:2.21~4.06)、1.76(95%CI:1.16~2.69)、1.46(95%CI:1.14~1.88)倍。女童的父母体质指数对儿童发生超重肥胖的风险高于男童,淄博儿童发生超重肥胖的风险高于南京。结论学龄前儿童超重肥胖率较高,父母体质指数是儿童超重肥胖发生的危险因素,且存在地区、性别差异。

Objective To investigate the prevalence of overweight and obesity among preschool children in urban areas;to study the relationship between parental body mass index and overweight and obesity of preschool children.Methods A total of 2037 preschool children from 4 kindergartens in Nanjing of Jiangsu Province and Zibo of Shandong Province were selected as subjects.Univariate logistic model was used to analyze the relationship between parental body mass index and overweight and obesity of preschool children.Results The prevalence rate of overweight and obesity among preschool children in urban areas was 24.30%;the overweight rate was 13.16%(male 14.54%,female 11.66%),and obesity rate was 11.14%(male 12.28%,female 9.92%).After adjusting for factors such as region,gender and age,parents′overweight and obesity was the risk factor of overweight and obesity of preschool children.Preschool children whose parents were overweight and obese,only mother was overweight and obese,and only father was overweight and obese showed 3.00(95%CI:2.21-4.06),1.76(95%CI:1.16-2.69)and 1.46(95%CI:1.14-2.69)times higher than children with normal or lean parents,respectively.The risk of overweight and obesity of girls′parents′body mass index was higher than that of boys,and the risk of overweight and obesity of children in Zibo was higher than that in Nanjing.Conclusion The prevalence rates of overweight and obesity in preschool children were high.The parental body mass index was a risk factor of overweight and obesity incidence in preschool children.There are regional and gender differences.
