Previous work has documented associations between poverty and HIV. Understanding of these relationships at local levels could help target prevention efforts; however, HIV surveillance systems do not capture individual-level poverty measures. We utilized the Public Health Disparities Geocoding Project methods to examine HIV rates by census tract poverty. HIV rates and rate ratios were computed by census tract poverty (< 5.0, 5.0-9.9, 10.0-19.9, > 20.0% of individual below the federal poverty level) for all races and stratified by Black and White race using Poisson regression. We observed higher HIV rates in the highest poverty gradient compared to the lowest poverty gradient for all races combined and among White cases. After adjustment, HIV rates were similar across poverty gradients for all comparisons. Our findings suggest that the association between poverty and HIV may differ by subpopulation, while demonstrating the potential for HIV prevention targeting residents of high poverty areas.
先前的工作已经记录了贫困与 HIV 之间的关联。了解这些地方层面的关系可以帮助针对预防工作；然而，HIV 监测系统无法获取个人层面的贫困措施。我们利用公共卫生差异地理编码项目方法，按普查区贫困程度检查 HIV 发病率。利用泊松回归，我们计算了所有种族按普查区贫困程度（低于联邦贫困线的个人比例<5.0%、5.0-9.9%、10.0-19.9%、>20.0%）和按黑人和白人种族分层的 HIV 发病率和发病率比。我们观察到，与最低贫困梯度相比，所有种族中最高贫困梯度的 HIV 发病率更高，而白人病例中则更高。调整后，所有比较的贫困梯度之间的 HIV 发病率相似。我们的研究结果表明，贫困与 HIV 之间的关联可能因亚人群而异，同时也表明了针对高贫困地区居民进行 HIV 预防的潜力。
