The impact of access to prenatal health insurance for noncitizen women on child health.

Objective: To estimate the effects of prenatal public health insurance targeting noncitizens on the health of U.S.‐born children of noncitizen mothers beyond birth outcomes. Data Sources and Study Setting: This paper uses the restricted version of the 1998–2014 National Health Interview Survey with state‐level geographic identifiers. Study Design: The empirical strategy compares outcomes in states that adopted the Children's Health Insurance Plan (CHIP) Unborn Child Option with states that never adopted or adopted it at different times, controlling for differences in the pre‐treatment period. I use a flexible event‐study analysis to quantify the effects of the Unborn Child Option on noncitizen women's health insurance coverage, health care utilization, and their children's health. Data Collection/Extraction Methods: All data are derived from pre‐existing sources. Principal Findings: The study finds that the impact of the Unborn Child Option is a 4.7%‐point increase in public health insurance coverage (p < 0.01) and 0.48 more doctor's office visits (p < 0.1) annually among noncitizens of childbearing ages. Subsequently, the reform leads to a 7%‐point rise in the rate of parents reporting their 4–6‐year‐old children are in "excellent" or "very good" health (p < 0.01). While no improvements are evident at birth and at younger ages, observed health improvements begin to appear by preschool age. Conclusions: The study contributes to the literature by providing evidence that certain benefits of in‐utero public health insurance targeting noncitizens may appear several years after birth, specifically around preschool age.
