We examined geographic and racial variation in cancer mortality within the state of Georgia, and investigated the correlation between the observed spatial differences and county-level characteristics. We analyzed county-level cancer mortality data collected by the Centers for Disease Control and Prevention on breast, colorectal, lung, and prostate cancer mortality among adults (aged ≥ 18 years) in 159 Georgia counties from years 1999 through 2019. Geospatial methods were applied, and we identified hot spot counties based on cancer mortality rates overall and stratified by non-Hispanic white (NH-white) and NH-black race/ethnicity. Among all adults, 5.0% (8 of 159), 8.2% (13 of 159), 5.0% (8 of 159), and 6.9% (11 of 159) of Georgia counties were estimated hot spots for breast cancer, colorectal, lung, and prostate cancer mortality, respectively. Cancer mortality hot spots were heavily concentrated in three major areas: (1) eastern Piedmont to Coastal Plain regions, (2) southwestern rural Georgia area, or (3) northern-most rural Georgia. Overall, hot spot counties generally had higher proportion of NH-black adults, older adult population, greater poverty, and more rurality. In Georgia, targeted cancer prevention strategies and allocation of health resources are needed in counties with elevated cancer mortality rates, focusing on interventions suitable for NH-black race/ethnicity, low-income, and rural residents.
我们研究了佐治亚州内癌症死亡率的地理和种族差异,并调查了观察到的空间差异与县一级特征之间的相关性。我们分析了疾病控制与预防中心收集的 159 个佐治亚县的县一级癌症死亡率数据,这些数据涉及 1999 年至 2019 年期间成年(年龄≥18 岁)人群的乳腺癌、结直肠癌、肺癌和前列腺癌死亡率。我们应用了地理空间方法,并根据非西班牙裔白人(NH-白)和非西班牙裔黑人(NH-黑)种族/族裔,确定了总体癌症死亡率和分层癌症死亡率的热点县。在所有成年人中,估计有 5.0%(159 个县中的 8 个)、8.2%(159 个县中的 13 个)、5.0%(159 个县中的 8 个)和 6.9%(159 个县中的 11 个)的佐治亚县分别是乳腺癌、结直肠癌、肺癌和前列腺癌死亡率的热点县。癌症死亡率热点县主要集中在三个主要地区:(1)东部皮埃蒙特到沿海平原地区,(2)佐治亚州西南部农村地区,或(3)佐治亚州最北部农村地区。总体而言,热点县的 NH-黑成年人比例、老年人口比例、贫困程度和农村程度普遍较高。在佐治亚州,需要在癌症死亡率较高的县实施有针对性的癌症预防策略和卫生资源配置,重点关注适合 NH-黑种族/族裔、低收入和农村居民的干预措施。
