AbstractNot using the infant back sleep position is an established risk factor for sudden unexpected infant death (SUID). Infant bed sharing may also increase SUID risk, particularly under certain circumstances. Both of these infant sleeping behaviors are disproportionately higher among Black mothers. We explored the relationship between not using the infant back sleeping and infant bed sharing, developed separate risk factor profiles for these behaviors, and identified maternal characteristics contributing to racial differences in their practice. Merged 2004-2005 birth certificate and Pregnancy Risk Assessment Monitoring System data for 2,791 non-Hispanic Black and White Florida women were evaluated using univariable and multivariable analyses to develop risk factor profiles for infrequent back sleeping and frequent bed sharing. Cross-product interaction terms were introduced to identify factors contributing to racial differences. Infrequent back sleeping and frequent bed sharing were reported by two-thirds of Black women and one-third of White women. There was no association between the infant sleeping behaviors when adjusted for race (adjusted odds ratio [aOR], 1.04; 95% CI, 0.83-1.31). The infant sleeping behaviors shared no common independent maternal characteristics. Father acknowledgement on the birth certificate was a strong contributor to racial differences in infrequent back sleeping while breastfeeding, trimester of entry to prenatal care, and maternal depression revealed notable racial differences for bed sharing. Behavior-specific and race-specific public health messages may be an important public health strategy for reducing risky infant sleeping behaviors and decreasing SUIDs.
