IntroductionAlthough previous public health efforts have focused on redressing health disparities associated with insufficient gestational weight gain, examination of the impact of excessive gestational weight gain is warranted currently given the 2009 revision of the Institute of Medicine (IOM) gestational weight gain guidelines for obese women coupled with rising rates of obesity, particularly among African American women.Materials And MethodsIn the years 2004-2008, 4619 African American and Caucasian women gave birth to a single, live, and full-term infant, completed Arkansas Pregnancy Risk Assessment Monitoring System questions about gestational weight gain and prepregnancy weight status, and gained within or in excess of the guidelines. Logistic regression was used to identify sociodemographic and health variables associated with the odds of exceeding the 2009 IOM guidelines overall and by race.ResultsRegardless of race, overweight (odds ratio [OR]=3.21; 95% confidence interval [CI]: 2.64-3.91) and obese (OR=4.37; 95% CI: 3.50-5.46) women had significantly higher odds of gaining excessively, as compared with normal weight women. In the multivariate model, women who were overweight or obese prepregnancy and who were married had higher odds of exceeding the IOM guidelines, while lower odds of exceeding the guidelines were seen among African American women, those who had Medicaid at any point in their pregnancy, who were multiparous, and those of Hispanic ethnicity.DiscussionThese findings can inform efforts to promote appropriate gestational weight gain among those at highest risk (i.e., overweight/obese women) and facilitate targeting to produce greatest improvement in the health of mothers and children.
