Abstract
OBJECTIVES: In the United States, Title X facilities are understood to be an effective starting point for improving teenagers' reproductive health outcomes, including unintended pregnancy. We investigate geographic accessibility of Title X facilities and the relationship between geographic accessibility of Title X facilities and teenage birth rates in the state of North Carolina (NC). METHODS: Vehicular travel time from each ZCTA to its nearest Title X facility was calculated using a geographic information system and summarized as the indicator of geographic accessibility. We used bivariate and multiple spatial lag regressions to evaluate the relationship between ZCTA-level teenage birth rates (n = 754) in 2016 and geographic accessibility to a Title X facility, as well as socioeconomic and demographic factors. RESULTS: Nearly 60% of teenage women lived 30 min or less from a Title X funded facility, while approximately 12% of women lived 60 min or more from the nearest facility. In the regression models, percent non-Hispanic White, percent Hispanic, percent in Poverty, percent not enrolled in school, and population density were associated with teenage birth rates; however, geographic accessibility was only associated in the bivariate model. CONCLUSIONS: Our findings show that geographic accessibility of Title X facilities is lower in NC than in other states. However, our results suggest that geographic accessibility is not related to teenage birth rates. Overall, these findings may indicate that publicly funded family planning facilities are underutilized by proximal populations or factors other than proximity act as a barrier to utilization.
