Practices and Policies That Support Breastfeeding Among Military Women: A Systematic Review.

Abstract

BACKGROUND: Previous and limited assessments of breastfeeding in women serving on active duty in the U.S. military demonstrate varied and conflicting data regarding breastfeeding outcomes. Disparities exist within the military where enlisted service members have consistently lower rates of breastfeeding duration compared to officers. Yet, little is known about successful care practices and military policies that promote breastfeeding in military women. The aim of this systematic review is to examine care practices and military policies associated with increased breastfeeding initiation and duration among women serving in the U.S. military. MATERIALS AND METHODS: We searched Cochrane Database, Cumulative Index of Nursing and Allied Health Literature, PubMed, and PsycInfo for studies published from 2000 to 2022 that included U.S. military personnel and that focused on care practices and military policies that support breastfeeding. Our search terms included (breastfeeding OR breastfeed AND military) and (lactation OR lactating AND military). We included randomized controlled trials, quasi-experimental, cohort, cross-sectional, and other observational designs. We evaluated potential bias in studies using the Evidence Project Risk of Bias Tool and synthesized the overall evidence using the Johns Hopkins Nursing Evidence-Based Practice Synthesis and Recommendations Tool. RESULTS: We included 14 studies that were independently reviewed by two authors. Breastfeeding initiation rates among military women were between 66% and 98%, and breastfeeding duration rates at 6 months ranged from 13% to 62%. In these studies, researchers examined various inpatient care practices (skin-to-skin care, timing of circumcision, and infant baths) (n = 3), care delivered by different types of providers (n = 3), group versus individual prenatal care (n = 2), breastfeeding education (n = 2), length of maternity leave (n = 2), and workplace support (n = 2). Skin-to-skin contact following delivery was positively associated with breastfeeding outcomes. There is insufficient evidence to determine if care by different types of medical providers, different types of prenatal care and education, timing of circumcision or baths, length of maternity leave, and workplace support influence breastfeeding outcomes. CONCLUSION: Certain perinatal practices designed to encourage early skin-to-skin contact appear to improve breastfeeding initiation and duration among women serving in the U.S. military. However, there is an overall lack of quality evidence supporting effective practices and policies associated with increased breastfeeding initiation and duration in this population. Given the recent movement toward policy changes that support pregnant and postpartum service members across services, more research is needed to determine the impact of these and other practices and policies on breastfeeding rates, specifically among enlisted service members who have demonstrated lower breastfeeding rates than officers.
