为了减少差异，有必要确定导致性传播感染地域差异的预测因素。本研究评估了避孕套可得性和可及性的空间关系，以便更好地确定性传播感染地域差异的决定因素。我们对潜在的安全套销售机构进行了电话审计。进行描述性分析以检测不同商店和商店类型的避孕套销售特征的差异。通过地理编码、地图绘制和空间分析来衡量避孕套的可获得性。圣路易斯市共有850家潜在的安全套销售机构参与了安全套可获得性和可获得性审计；29%的人卖避孕套。在整个研究区域确定了几个重要的地理商店集群。第一个是在城市北部销售避孕套的便利店和加油站较少，而在城市西南部和中部的非便利店环境中销售避孕套的可能性较小。此外，发放免费安全套的地点主要集中在市中心。然而，在城市的北部地区，既不是便利店也不是加油站的商家很少，而那里也是安全套销售最集中的地区。这项初步研究是为了提供证据，证明避孕套的可获得性和可获得性因地理区域而异，这可能是围绕避孕套使用的社会规范的决定因素，并最终影响性病发病率。
Identifying predictors that contribute to geographic disparities in sexually transmitted infections (STIs) is necessary in order to reduce disparities. This study assesses the spatial relationship condom availability and accessibility in order to better identify determinants of geographic disparities in STIs. We conducted a telephone-based audit among potential-condom selling establishments. Descriptive analyses were conducted to detect differences in condom-selling characteristics by stores and by store type. Geocoding, mapping, and spatial analysis were conducted to measure the availability of condoms. A total of 850 potential condom-selling establishments participated in the condom availability and accessibility audit in St. Louis city; 29 % sold condoms. There were several significant geographic clusters of stores identified across the study area. The first consisted of fewer convenience stores and gas stations that sold condoms in the northern section of the city, whereas condoms were less likely to be sold in non-convenience store settings in the southwestern and central parts of the city. Additionally, locations that distributed free condoms clustered significantly in city center. However, there was a dearth of businesses that were neither convenience stores nor gas stations in the northern region of the city, which also had the highest concentration of condoms sold. This initial study was conducted to provide evidence that condom availability and accessibility differ by geographic region, and likely are a determinant of social norms surrounding condom use and ultimately impact STI rates.
