背景资料：儿童超重是一个重大的公共卫生问题，但人们对幼儿超重的预测因素知之甚少。目的：我们的目的是确定预测幼儿园超重的单独和组合因素。设计：我们分析了来自幼儿纵向研究-出生队列的全国代表性数据，这是一项纵向队列研究，对6800名儿童从出生到幼儿园进行了跟踪。进行多变量逻辑回归和递归分割分析（RPA），以确定预测幼儿园超重的父母，产前/怀孕，婴儿和幼儿因素的个人和集群。主要结果是幼儿园超重[体重指数（BMI）>= 85百分位数，包括肥胖]。通过使用组合（来自131个因素）的身高体重或BMI >= 85百分位数的早期年龄，种族/民族，母亲妊娠期糖尿病史，出生体重，以及固体食物引入和儿童站立时的年龄，RPA确定了6个幼儿园超重患病率特别高的群体（56-100%）和2个患病率特别低的群体（11- 100%）。15%）。学龄前BMI>= 85百分位数的儿童（77%）和2岁时BMI>= 85百分位数的儿童、母亲患有妊娠期糖尿病的白色儿童（100%）和出生体重
Background: Childhood overweight is a substantial public-health problem, but little is known about predictors of early childhood overweight.Objective: We aimed to identify factors-alone and in combination-that predict kindergarten overweight.Design: We analyzed nationally representative data from the Early Childhood Longitudinal Study-Birth Cohort, a longitudinal cohort study of 6800 children followed from birth through kindergarten. Multivariable logistic regression and recursive partitioning analysis (RPA) were performed to identify individual and clusters of parental, prenatal/pregnancy, infant, and toddler factors predicting kindergarten overweight. The main outcome was kindergarten overweight [body mass index (BMI) >= 85th percentile, which includes obesity].Results: The prevalence of kindergarten overweight was 32%. By using combinations (derived from 131 factors) of a weight-for-length or BMI >= 85th percentile at earlier ages, race/ethnicity, a maternal gestational diabetes history, birth weight, and ages at solid-food introduction and the child pulling to a stand, the RPA identified 6 groups with a particularly high prevalence of kindergarten overweight (56-100%) and 2 groups with a particularly low prevalence (11-15%). An especially high prevalence was noted for children with a >= 85th BMI percentile at preschool age (77%) and in children with a >= 85th BMI percentile at 2 y old, for white children whose mother had gestational diabetes (100%), and for minority children with a birth weight
