Relationship between weight retention at 6 weeks postpartum and the risk of large-for-gestational age birth in a second pregnancy in China: a retrospective cohort study.

ABSTRACT:

Objective

We aimed to investigate the association between weight retention at 6 weeks postpartum after the first pregnancy and large-for-gestational age (LGA) risk in a subsequent pregnancy.

Study design

A retrospective cohort study.

Setting

A tertiary hospital of China.

Participants

5950 Chinese singleton pregnancies that delivered their second singletons between 28 and 42 weeks of gestation.

Outcomes measures

We calculated the weight retention at 6 weeks postpartum after the first pregnancy (the body mass index (BMI) at 6 weeks after the first birth minus the prepregnant BMI of the first pregnancy) and the gestational weight gain in the second pregnancy. We used the logistic regression to obtain adjusted OR. We determined the relationship between mater
