Costs associated with policies regarding alcohol use during pregnancy: results from 1972-2015 vital statistics

This study finds negative effects from policies including mandatory warning signs about drinking while pregnant; categorizing drinking while pregnant as child abuse/neglect; limiting criminal prosecution; and priority substance abuse treatment for pregnant women. They lead to thousands of babies being born low birthweight or preterm birth each year, and cost hundreds of millions of dollars annually.

Person-centered maternity care in low-income and middle-income countries: analysis of data from Kenya, Ghana and India

This is the first known study to measure person-centered maternity care in more than one country with the same tool. Researchers surveyed women in Kenya, Ghana and India using a scale to measure their experience of care. The results showed that serious efforts are needed to improve person-centered maternity care.

Trajectories of women's physical and psychosocial health following obstetric fistula repair in Uganda: a longitudinal study

This is the first study to look at year-long trajectories of physical and psychosocial health after fistula repair surgery in Uganda. Researchers found that most women reported dramatic improvements in their physical and psychosocial health, mostly within the first 6 months.

Using index of concentration at the extremes as indicators of structural racism to evaluate the association with preterm birth and infant mortality-California, 2011-2012.

This study found that in zip codes with a higher concentrations of racially and/or economically disadvantaged groups, Black women had a higher odds of preterm birth and infant mortality. Women in the least privileged zip codes had a more than 25% higher chance of having a preterm birth compared with women who lived in the most privileged zip codes.
