Prepregnancy obesity and breastfeeding noninitiation in the United States: an examination of racial and ethnic differences.

Abstract

BACKGROUND:

Prepregnancy overweight/obesity can adversely affect breastfeeding initiation, but studies examining this association among different racial/ethnic groups of U.S. women are limited. This study used a large, nationally representative sample to assess racial/ethnic differences in breastfeeding noninitiation among U.S. women of different body mass index (BMI) classifications.

MATERIALS AND METHODS:

This study analyzed data from the Pregnancy Risk Assessment Monitoring System, including 95,141 women who delivered a live, singleton baby from 2009 to 2011 and provided BMI and breastfeeding information. Prepregnancy BMI was categorized as underweight (< 18.5 kg/m(2)), normal weight (18.5-24.9 kg/m(2)), overweight (25.0-29.9 kg/m(2)), and obese (≥30.0 kg/m(2)). Breastfeeding initiation was reported as having ever breastfed after delivery (yes or no). Adjusted models, which included only potential confounders resulting in a 10% or greater change in estimate, generated adjusted odds ratios (AOR) and 95% confidence intervals (CI) for breastfeeding noninitiation. Analysis was stratified by race/ethnicity.

RESULTS:

Compared with normal weight non-Hispanic white women, the odds of breastfeeding noninitiation were 17% and 25% higher among overweight (AOR=1.17, 95% CI=1.07-1.29) and obese (AOR=1.25, 95% CI=1.14-1.36) non-Hispanic white women, respectively. Among non-Hispanic black women, the odds of breastfeeding noninitiation were 29% higher only in obese women compared with normal weight non-Hispanic black women. No association was observed among Hispanic women or women of other races.

CONCLUSIONS:

Prepregnancy BMI is a significant predictor for breastfeeding noninitiation for non-Hispanic white and non-Hispanic black women. Further exploration of the differences underlying the association between prepregnancy BMI and breastfeeding behaviors among racial subpopulations of women in the United States is warranted.
