Can Expanding Contraceptive Access Reduce Adverse Infant Health Outcomes?
利用科罗拉多州私人资助的家庭计划项目，研究发现向低收入女性扩大长效可逆避孕药具获取，能降低极早产率和婴儿死亡率，每千活产减少1.1例极早产和0.9例婴儿死亡，其中婴儿猝死综合征降幅最大。
<h3>Abstract</h3> This paper uses the implementation of a privately funded family planning program in Colorado to demonstrate that expanding access to long-acting reversible contraceptives to lower income women creates positive selection in the health of the children being born, reducing the rates of extremely preterm births and infant mortality. My most conservative estimates suggest reductions of 1.1 extremely preterm births and 0.9 infant deaths per 1,000 live births, with the largest reduction in deaths due to Sudden Infant Death Syndrome (SIDS). This suggests that expanding contraceptive access could help close the infant mortality gap between the U.S. and other leading economies.
