Gestational weight gain in consecutive pregnancies.
OBJECTIVE
The purpose of this study was to examine the association between gestational weight gain (GWG) in a woman's first and second pregnancies.


METHODS
We conducted a retrospective observational cohort study of 27,771 women with their first and second births in North Carolina's Pregnancy Nutrition Surveillance System database from 1996-2004. GWG was categorized as inadequate, appropriate, or excessive, according to 2009 Institute of Medicine guidelines. Covariate adjusted polytomous logistic regression was used to test the association between GWG category in the first and second pregnancy.


RESULTS
Compared with women with appropriate GWG in their first pregnancy, women with excessive GWG in their first pregnancy had an odds ratio of 2.6 (95% confidence interval, 2.4-2.7) for excessive GWG in their second pregnancy. Women with inadequate GWG in their first pregnancy were similarly likely to repeat this category in their subsequent pregnancy.


CONCLUSIONS
GWG category in a woman's first pregnancy is a significant predictor of GWG category in her subsequent pregnancy.
