This study used US National Longitudinal Study of Youth data to explore how exposure to different socioeconomic conditions (proxied by maternal education) before birth can shape child weight. Using endogenous selection regression models, the findings suggest that educational selectivity affects weight gain. Mothers whose mothers graduated from high school were more likely to complete high school, and mothers reared in an intact family had higher levels of education. However, mothers who had given birth as a teenager had the same educational outcomes as mothers who gave birth in their post-teenage years. Based on this intergenerational educational selectivity, caretaking (e.g. breast-feeding) was found to be associated with a lower child body mass index (BMI), while negative maternal characteristics (e.g. mothers with high BMIs) were associated with higher child BMIs. Thus, educational selectivity influences child health through values passed on to the child and the lifestyle in which the child is reared. Maternal education may be tied to parenting, which relates to child obesity risk.
本研究使用美国国家青年纵向研究数据，以探究出生前暴露于不同社会经济状况（以母亲教育程度为代理变量）如何影响儿童体重。使用内生选择回归模型，研究结果表明教育选择性会影响体重增加。母亲的母亲高中毕业的母亲更有可能完成高中学业，在完整家庭中长大的母亲受教育程度更高。然而，青少年时期生育的母亲与成年后生育的母亲教育结果相同。基于这种代际教育选择性，发现育儿方式（如母乳喂养）与较低的儿童体重指数（BMI）相关，而母亲的负面特征（如高BMI的母亲）与较高的儿童BMI相关。因此，教育选择性通过传递给孩子的价值观和养育孩子的生活方式影响儿童健康。母亲教育程度可能与育儿方式有关，而育儿方式又与儿童肥胖风险相关。
