The objective of this study is to examine associations between state-level breastfeeding support and breastfeeding practices, controlling for women's status, in the U.S. We used publicly available data on state-level breastfeeding practices and support (international board-certified lactation consultants (IBCLC), births in Baby-Friendly hospitals, and La Leche League Leaders) for births in 2015 from the CDC Breastfeeding Report Card (2018) and other CDC reported data, and indicators of women's status from the Institute for Women's Policy Research reports (2015). We conducted an ecological study to estimate incidence rate ratios of exclusive breastfeeding at six months and breastfeeding at 12 months with breastfeeding supports using bivariate and multivariable Poisson regression. Political participation, poverty, and employment and earnings were associated with breastfeeding practices, as was each breastfeeding support in bivariate analyses. After controlling for women's status, only IBCLCs were positively associated with rates of exclusive breastfeeding at 6 months and continued breastfeeding at 12 months. For every additional IBCLC per 1000 live births, the rate of exclusive breastfeeding at 6 months increased by 5 percent (95% CI 1.03, 1.07) and the rate of breastfeeding at 12 months increased by 4 percent (95% CI 1.02, 1.06). Political participation, poverty, and employment and earnings were associated with breastfeeding practices, indicating a relationship between women's political and economic status and their breastfeeding practices in the U.S. Given the influence of women's status, increasing the number of IBCLCs may improve breastfeeding practices.
