State-Level Social and Economic Policies and Their Association With Perinatal and Infant Outcomes

Pumps: A Possible Tool to Promote More Equitable Lactation Outcomes

Pregnant individuals and infants in the US are experiencing rising morbidity and mortality rates. Breastfeeding is a cost-effective intervention associated with a lower risk of health conditions driving dyadic morbidity and mortality, including cardiometabolic disease and sudden infant death. Pregnant individuals and infants from racial/ethnic subgroups facing the highest risk of mortality also have the lowest breastfeeding rates, likely reflective of generational socioeconomic marginalization and its impact on health outcomes. Promoting breastfeeding among groups with the lowest rates could improve the health of dyads with the greatest health risk and facilitate more equitable, person-centered lactation outcomes. Multiple barriers to lactation initiation and duration exist for families who have been socioeconomically marginalized by health and public systems. These include the lack of paid parental leave, increased access to subsidized human milk substitutes, and reduced access to professional and lay breastfeeding expertise. Breast pumps have the potential to mitigate these barriers, making breastfeeding more accessible to all interested dyads. In 2012, The Patient Protection and Affordable Care Act (ACA) greatly expanded access to pumps through the preventative services mandate, with a single pump now available to most US families. Despite their near ubiquitous use among lactating individuals, little research has been conducted on how and when to use pumps appropriately to optimize breastfeeding outcomes. There is a timely and critical need for policy, scholarship, and education around pump use given their widespread provision and potential to promote equity for those families facing the greatest barriers to achieving their personal breastfeeding goals.

The association of state percent uninsured and the likelihood of low birth weight: evidence from the 2016-2019 Pregnancy Risk Assessment Monitoring System

OBJECTIVE

To evaluate the association of state-level lack of health insurance among women of reproductive age with variation in state low birth weight (LBW) rates.

STUDY DESIGN

This cross-section study analyzes data from the 2016-2019 Pregnancy Risk Assessment Monitoring Survey for respondents with singleton, live births.

METHODS

Respondents were divided into groups by state-level percent of uninsured women aged 19-44 years. Poisson regression was used to model the association between state percent uninsured and likelihood of LBW, controlling for individual sociodemographic and clinical risk factors. Sensitivity analyses were done for Medicaid and non-Hispanic Black subpopulations and alternative state characteristics, including Gini coefficients, total and public welfare expenditures, and state reproductive rights rankings.

RESULTS

In adjusted multiple regression analyses, compared to respondents from states with <7% uninsured, respondents from states with 7% or more uninsured had an increased risk of LBW status (7-8.99% uninsured: adjusted incidence rate ratio [aIRR] 1.11, 95% confidence interval [CI] 1.04-1.18; 9-11.99% uninsured: aIRR 1.09, 95% CI 1.02-1.17; >11.99% uninsured: aIRR 1.15, 95% CI 1.08-1.22). However, there was no evident dose-response gradient. Sensitivity analyses produced virtually identical findings for subpopulations, and no other state characteristics were significant.

CONCLUSION

States with the highest level of insurance coverage had a significantly lower LBW rate than other states. However, there was little evidence for greater odds of LBW with the highest levels of uninsured. Individual risk factors dominated LBW models, while state differences in income inequality, reproductive health policy, and per capita spending explained little of the variance in LBW.

US State Policy Contexts and Population Health

Policy Points This Perspective connects the dots between the polarization in US states' policy contexts and the divergence in population health across states. Key interlocking forces that fueled this polarization are the political investments of wealthy individuals and organizations and the nationalization of US political parties. Key policy priorities for the next decade include ensuring all Americans have opportunities for economic security, deterring behaviors that kill or injure hundreds of thousands of Americans each year, and protecting voting rights and democratic functioning.
