Abstract
The objective of this study was to assess the effect of WLS on pregnancy and delivery complications in women who had WLS compared to women with obesity who did not undergo WLS. We used the National Inpatient Sample data from 2012 to 2017, with a study population of women between the ages of 20 and 44 who had a maternal admission code in the NIS data (n = 663,795). Weighted logistic regression models were fitted and the models were stratified by race. Covariates included age, race, primary payer, previous cesarean delivery, physical health comorbidities, and depression. There were decreased odds of gestational diabetes in women of all races (aORall = 0.47, 95% CIall = 0.44-0.49). There were decreased odds for gestational hypertension in women of all races (aORall = 0.55, 95% CIall = 0.51-0.59). Compared to women who did not have WLS, there were lower odds of cesarean delivery among women with a history of WLS (aORall = 0.62, 95% CIall = 0.60-0.65), which was true for White women, Black women, and Latinas with a history of WLS (aORWhite = 0.57, 95% CIWhite = 0.53-0.60; aORBlack = 0.67, 95% CIBlack = 0.61-0.74; aORLatina = 0.71, 95% CILatina = 0.64-0.78). Overall, women with history of WLS had lower odds of most of the pregnancy outcomes (gestational diabetes, gestational hypertension, pre-eclampsia/eclampsia, and cesarean delivery) with results mediated by race.
