Objectives:
We investigated the within-group and between-group variation in prenatal HIV testing in a sample of low-income pregnant and recently postpartum women.
Methods:
Multivariable linear regression was used to estimate proportional differences in prenatal HIV testing for the total sample and stratified by race.
Results:
In bivariate analyses, race and site of care jointly affected the probability of being tested. Hispanic women had the highest probability of being tested in public practice settings but relative to white women, black women had a higher probability of being tested in public and private practice settings. Predictors of prenatal HIV testing differed by race. Receiving prenatal care in a community health center or hospital outpatient clinic increased the probability of testing for Hispanics. Being a recent victim of intimate partner violence was associated with less frequent testing for blacks. Positive beliefs about HIV screening, while significant for blacks and Hispanics, was the only factor associated with testing for whites.
Conclusion:
Our data suggest that racial biases may be influencing providers' approach to testing, rather than CDC's 2001 guidelines for HIV screening of pregnant women. Study findings are being used to modify social marketing campaigns and improve provider trainings regarding prenatal HIV testing.
