Neighborhood risk and prenatal care utilization in Rhode Island, 2005–2014

Abstract

Background

The importance of prenatal care is undeniable, as pregnant persons who receive on-time, adequate prenatal care have better maternal and infant health outcomes compared with those receiving late, less than adequate prenatal care. Previous studies assessing the relationship between neighborhood factors and maternal health outcomes have typically looked at singular neighborhood variables and their relationship with maternal health outcomes. In order to examine a greater number of place-based risk factors simultaneously, our analysis used a unique neighborhood risk index to assess the association between cumulative risk and prenatal care utilization, which no other studies have done.

Methods

Data from Rhode Island Vital Statistics for births between 2005 and 2014 were used to assess the relationship between neighborhood risk and prenatal care utilization using two established indices. We assessed neighborhood risk with an index composed of eight socioeconomic block-group variables. A multivariate logistic regression model was used to examine the association between adequate use and neighborhood risk.

Results

Individuals living in a high-risk neighborhood were less likely to have adequate or better prenatal care utilization according to both the APNCU Index (adjusted odds ratio [aOR] 0.91, 95% confidence interval [CI] 0.87–0.95) and the R-GINDEX (aOR 0.88, 95% CI 0.85–0.91) compared with those in low-risk neighborhoods.

Conclusion

Understanding the impact of neighborhood-level factors on prenatal care use is a critical first step in ensuring that underserved neighborhoods are prioritized in interventions aimed at making access to prenatal care more equitable.
