Comparison of birth outcomes of mothers covered by Medicaid versus those privately insured when accounting for social determinants of health.

OBJECTIVES

To determine the association between maternal health insurance type and birth outcomes [prematurity, small for gestational age (SGA), Term/Appropriate for gestational age NICU admission (Term/AGA-NICU) & composite birth outcomes (CBO)] accounting for social determinants of health.

DESIGN/

METHODS

A cross-sectional study of maternal surveys and birth certificate data of singleton live births in NY born to mothers with Medicaid (M) or Private Insurance (PI).

RESULTS

1015 mothers [M = 631, PI = 384) included. Individual birth outcomes did not differ between groups. Adjusting for social, demographic and clinical covariates, M mothers had similar odds of preterm birth, SGA, Term/AGA-NICU admission and CBO compared to PI.

CONCLUSIONS

M mothers were as likely as PI mothers to deliver a preterm, SGA or a Term/AGA-NICU infant after controlling for social determinants of health. Despite more social adversity among enrollees, our study suggests NY Medicaid recipients have similar birth outcomes to privately insured, socially advantaged women.
