The Authors Respond to Issues With the Consecutive-Pregnancies Approach

摘要

We thank Drs. Snowden and Leonard ( ) for elaborating on the generalizability of our results on the relationship between incident obesity and stillbirth ( ). To quantify the association between obesity and stillbirth, we restricted our analyses to women who were not obese at the time of their first pregnancy. Women who became obese prior to a subsequent pregnancy were then classified as exposed.
