Risk of sleep-related infant deaths can be reduced by improving safe sleep practices.

Objectives The study objective was to examine the prevalence of maternal multivitamin use and associations with preterm birth (<37 weeks gestation) in the United States. We additionally examined whether associations differed by race/ethnicity. Methods Using the Pregnancy Risk Assessment Monitoring System, we analyzed 2009-2010 data among women aged ≥18 years with a singleton live birth who completed questions on multivitamin use 1 month prior to pregnancy (24 states; n = 57,348) or in the last 3 months of pregnancy (3 states, n = 5095). Results In the month prior to pregnancy, multivitamin use ≥4 times/week continued to remain low (36.8 %). In the last 3 months of pregnancy, 79.6 % of women reported using multivitamins ≥4 times/week. Adjusting for confounders, multivitamin use 1-3 times/week or ≥4 times/week prior to pregnancy was not associated with preterm birth overall. Though there was no evidence of dose response, any multivitamin use in the last 3 months of pregnancy was associated with a significant reduction in preterm birth among non-Hispanic black women. Conclusions for Practice Multivitamin use during pregnancy may help reduce preterm birth, particularly among populations with the highest burden, though further investigations are warranted.

Perinatal morbidity and mortality are key indicators of a nation's health status. These measures of our nation's health are influenced by decisions made in health care facilities and by health care providers. As our health systems and health care for women and infants can be improved, there is an expectation that these measures of health will also improve. State-based perinatal quality collaboratives (PQCs) are networks of perinatal care providers including hospitals, clinicians, and public health professionals working to improve pregnancy outcomes for women and newborns through continuous quality improvement. Members of the collaborative are healthcare facilities, primarily hospitals, which identify processes of care that require improvement and then use the best available methods to effect change and improve outcomes as quickly as possible. The Division of Reproductive Health at the Centers for Disease Control and Prevention is collaborating with state-based PQCs to enhance their ability to improve perinatal care by expanding the range of neonatal and maternal health issues addressed and including higher proportions of participating hospitals in their state PQC. The work of PQCs is cross-cutting and demonstrates how partnerships can act to translate evidence-based science to clinical care.
