目的：关于儿童保育使用与身体质量指数(BMI)、超重或肥胖发展的关系的研究显示出相互矛盾的结果。这项研究调查了2岁以下儿童的托儿所使用与BMI z得分和超重的关系，以及托儿所使用的关联性。方法：纵向数据来自荷兰考拉出生队列研究。问卷调查评估了儿童在7个月、1岁和2岁时的保育使用情况(N=2396)。使用1岁和2岁时评估的身高和体重来计算BMI z分数。超重被定义为体重指数z分数=第85个百分位数。使用反向线性和Logistic回归分析来检验托儿所使用对体重发展的影响。结果是：(1)1至2岁时的BMI z评分；(2)1至2岁间BMI z评分的变化；(3)1至2岁时超重与非超重的比较；以及(4)1至2年间从正常体重到超重与保持正常体重的变化。结果：1岁和2岁时的儿童保育使用(否/是)正向预测2岁时的BMI z得分，以及1至2岁时BMI z得分的变化。这些关联根据不同的协变量(例如，父母的工作时间)进行了调整。此外，托儿所的使用显著增加了1岁时超重的几率。在高强度(每周16小时)和有限的儿童保育(
Objectives: Studies regarding the association of child-care use with body mass index (BMI), overweight or obesity development show contradictory results. This study examined the relationship between child-care use and BMI z-scores and overweight, as well as associates of child-care use in children up to 2 years old.Methods: Longitudinal data originated from the Dutch KOALA Birth Cohort Study. Questionnaires assessed child-care use at ages 7 months and 1 and 2 years (N=2396). Height and weight assessed at 1 and 2 years were used to calculate BMI z-scores. Overweight was defined as a BMI z-score of >= 85th percentile. The influence of child-care use on weight development was tested using backward linear and logistic regression analyses. Outcomes were: (1) BMI z-score at 1 and 2 years; (2) change in BMI z-score between 1 and 2 years; (3) overweight vs non-overweight at 1 and 2 years; and (4) change from normal weight to overweight vs remaining normal weight between 1 and 2 years. The association between child-care use and parental background characteristics was tested using backward logistic regression analyses.Results: Child-care use (no/yes) at 1 and 2 years positively predicted BMI z-scores at age 2 years, as well as change in BMI z-score between 1 and 2 years. These associations were adjusted for various covariates (for example, parental working hours). Furthermore, child-care use significantly increased the odds of being overweight at age 1year. There were few differences in BMI or overweight between intensive (>16 h per week) and limited child-care use (
