Results: Data included 337,889 infants conceived in non-RTC zip codes and 60,825 infants in RTC zip codes. Relative to those in non-RTC zip codes, birthing parents of infants in RTC zip codes had lower socioeconomic status, were more likely to be born outside of the US, and were more likely to be non-Hispanic Black or Hispanic/Latino. Exposure to RTC during pregnancy was associated with a non-statistically significant change in infants’ probability of adverse birth outcomes (-0.46 percentage points; 95% CI -1.23, 0.30). This association was most pronounced among publicly insured birthing parents (-0.74, 95% CI -1.67, 0.20), Hispanic birthing parents (-1.28, 95% CI -2.27, - 0.29), and non-Hispanic white birthing parents (-1.11, 95% CI -2.37, 0.15).
Conclusion(s):
RTC was marginally associated with improved birth outcomes at the population level. The magnitude of associations varied substantially across population subgroups. Further research is needed to understand RTC’s potential as a population intervention to improve birth outcomes and promote child health equity.
