方法我们使用多变量线性和逻辑回归模型来估计在香港中国出生队列中6个月和3、5和11岁时的儿童保育与11岁时的体重指数（BMI）z评分和超重（包括肥胖）的关联。我们评估了协会是否因性别或社会经济地位（SEP）而异。我们采用多重插补缺失的暴露和confersider.Results的原始8327队列成员，7933是活着的，参与和生活在香港。在11岁时，6796人进行了临床BMI评估。更高的体感诱发电位与非正式护理有关。插补后，3年、5年或11年的非正式护理分别与较高的BMI z评分相关[3年0.10，95%置信区间（CI）0.03-0.18，5年0.12，95% CI 0.04-0.21，11年0.17，95% CI 0.04-0.31]和存在超重[比值比（OR）3年1.19，95% CI 1.03-1.37，5年OR 1.20，95% CI 1.03-1.40，11年OR 1.21，95% CI 1.02-1.45]，校正性别、SEP和出生体重z评分。目前的非正式护理有最强的关联。然而，5岁时的非正式儿童保育也起了作用。没有证据表明性别或SEP.Conclusions的差异，在一个发达的，非西方的设置，非正式的儿童保育与儿童肥胖。非正式儿童保育的可修改属性值得调查肥胖预防。
Methods We used multivariable linear and logistic regression models to estimate the association of child care at 6 months and at 3, 5 and 11 years with body mass index (BMI) z-score and overweight (including obesity) at 11 years in a Hong Kong Chinese birth cohort. We assessed whether associations varied with sex or socio-economic position (SEP). We used multiple imputation for missing exposures and confounders.Results Of the original 8327 cohort members, 7933 are alive, participating and living in Hong Kong. At similar to 11 years, 6796 had their BMI clinically assessed. Higher SEP was associated with informal care. After imputation, informal care at each of 3, 5 or 11 years was separately associated with higher BMI z-score [3 years 0.10, 95% confidence interval (CI) 0.03-0.18, 5 years 0.12, 95% CI 0.04-0.21, 11 years 0.17, 95% CI 0.04-0.31] and with the presence of overweight [odds ratio (OR) 3 years 1.19, 95% CI 1.03-1.37, 5 years OR 1.20, 95% CI 1.03-1.40, 11 years OR 1.21, 95% CI 1.02-1.45], adjusted for sex, SEP and birth weight z-score. Current informal care had the strongest association. However, informal child care at 5 years also contributed. There was no evidence of differences by sex or SEP.Conclusions In a developed, non-Western setting, informal child care was associated with childhood obesity. Modifiable attributes of informal child care warrant investigation for obesity prevention.
