Abstract:

Background High incidence and prevalence of sexually transmitted infection (STI) in African Americans have been attributed to multiple factors. However, few articles have discussed spatial access to healthcare as a driver of disparities. The objective of this analysis was to evaluate the relationship between travel time to a healthcare provider and the likelihood of testing positive for one of three STIs in a sample of adults living in public housing. Methods One hundred and eight African-American adults in Atlanta, Georgia from November 2008 – June 2009, completed a survey that queried sexual behavior and healthcare utilization and had urine tested for, C. trachomatis, N. gonorrhoeae, and T. vaginalis by molecular methods. Travel time was a continuous variable capturing the number of minutes it took to reach the place where participants received most of their care. Multivariate analyses tested the hypothesis that individuals reporting longer travel times would be more likely to test positive for an STI. Travel time was squared to linearize its relationship to the outcome. Results Thirty six residents (37.5%) tested positive for ≥1 STI. A curvilinear relationship existed between travel time and STI status. When travel time was <48 minutes, a positive relationship existed between travel time and the odds of testing positive for an STI. An inverse relationship existed when travel time was ≥48 minutes. Conclusion Residents of impoverished communities experience a curvilinear relationship between travel time and STI status. We discuss possible factors that might have created this curvilinear relationship including voluntary social isolation.
