Black/White disparities in low birth weight pregnancy outcomes: an exploration of differences in health factors within a vulnerable population

Abstract

ABSTRACT The purpose of this paper is to (1) determine if there are racial differences between Non-Hispanic (NH) Black and NH White women in health ‘care’ factors associated with low birth weight (LBW), (2) to determine if there are differences across health ‘system’ factors, and (3) to explore if the factors account for racial differences. Univariate and multinomial nested logit (MNL) models were performed. Whereas the LBW percentage for NH White women was 8.1%, for NH Black women, the LBW percentage was 13.6% (p < .001). NH Black women were significantly more likely to be unmarried (p < .001) and earn less income (p < .001). For level of care, NH Black women were more likely to have LBW babies in neonatal care; whereas NH White women were more likely to have LBW babies in well-baby nurseries. Results from MNL models indicated that NH Black women were 1.79 times more likely to have a LBW baby. When controlling for health ‘care’ factors, the racial difference between NH Black and NH White women in the likelihood of having a LBW baby increased to an odds ratio of 2.26 (p = .038). There are racial differences in factors associated with LBW.
