背景：目前尚不清楚产后早期产妇血压（BP）升高对产妇体重状况和产后早期婴儿体重增加之间的关系有多大影响。目的探讨母亲产后1个月血压升高在母亲产后1个月体重增加与婴儿产后6个月体重增加之间的中介作用。研究对象为169对西班牙裔母婴。产后1个月测量孕妇体重指数（BMI）和血压。在产后1个月和6个月测量婴儿体重，以计算年龄别体重z评分（WAZ）。多元线性回归模型用于预测，Sobel检验用于确定中介。结果控制母亲孕前BMI、年龄、分娩方式、婴儿性别和婴儿出生体重后发现，母亲BMI（β = .29）和BP（β = .32）均预测婴儿WAZ增加（均P
Background It is unknown to what extent higher maternal blood pressure (BP) in early postpartum impacts the relationship between higher maternal weight status and greater infant weight gain in early postpartum. Objective To evaluate the mediating role of higher maternal BP at 1 month postpartum on the association between higher maternal weight status at 1 month postpartum and greater infant weight gain over 6 months postpartum. Methods Participants were 169 Hispanic mother-infant pairs. Maternal body mass index (BMI) and BP were assessed at 1 month postpartum. Infant weight was measured at 1 and 6 months postpartum to calculate weight-for-age z scores (WAZ). Multiple linear regression models were used for prediction, and Sobel test was used to determine mediation. Results Controlling for maternal pre-pregnancy BMI, age, delivery mode, infant sex, and infant birth weight revealed that both maternal BMI (beta = .29) and BP (beta = .32) predicted infant WAZ gain (both P
