The importance of community resources for breastfeeding

Abstract

Breastfeeding has long-lasting effects on children’s cognition, behavioral, mental and physical health. Previous research shows parental characteristics (e.g., education, race/ethnicity, income level) are associated with breastfeeding initiation and duration. Further, research shows significant variation in access to community resources by race/ethnicity. It is unclear how community resources may impact breastfeeding practices and how this might intersect with maternal race/ethnicity. This study combined nationally-representative data from the Study of Attitudes and Factors Effecting Infant Care (SAFE), which surveyed US mothers immediately after the infant’s birth and at two to six months of infant age, with the Child Opportunity Index (COI) 2.0, a census tract measure of community resources associated with child development, to explore the association between community resources and breastfeeding initiation and whether this varies based on maternal race/ethnicity and country of birth. The SAFE Study used a stratified, two-stage, clustered design to obtain a nationally representative sample of mothers of infants, while oversampling Hispanic and non-Hispanic (NH) Black mothers. The SAFE study enrolled mothers who spoke English or Spanish across 32 US birth hospitals between January 2011 and March 2014. After accounting for individual characteristics, mothers residing in the highest-resourced communities (compared to the lowest) had significantly greater likelihood of breastfeeding. Representation in higher-resourced communities differed by race/ethnicity. Race/ethnicity did not significantly moderate the association between community resources and breastfeeding. In examining within race/ethnic groups, however, community resources were not associated with non-US born Black and Hispanic mothers’ rates of breastfeeding, while they were with US born Black and Hispanic mothers. Findings suggest that even health behaviors like breastfeeding, which we often associate with individual choice, are connected to the community resources within which they are made. Study implications point to the importance of considering the impact of the contextual factors that shape health and as a potential contributor to understanding the observed race/ethnicity gap.
