Goldstein ND, Palumbo AJ, Bellamy SL, et al. - Given that government expenditures on non–healthcare services can decrease infant mortality, but it is uncertain what types of spending have the greatest effect among high-risk groups, researchers quantified how US state government spending on various services impacted infant mortality rates (IMRs) over time and whether spending differentially decreased mortality in some subpopulations. Expenditures covered spending on education, social services, and environment and housing. Investment in non–healthcare services has been correlated with lower IMRs among certain high-risk populations. Continued investment in improved social and environmental services promises to further reduce IMR disparities.
