Chronic obstructive pulmonary disease (COPD) is one of the major causes of mortality worldwide and also reports high morbidity rates and the global burden COPD has continued to rise over the last several decades. The best-known COPD risk factors are tobacco smoke and air pollution, but genetics, age, sex, and socioeconomic status are additional factors. This study aimed to assess the spatial distribution of unscheduled COPD hospital admissions of men and women in the central area of Asturias during 2016-2018 and identify trends, spatial patterns, or clusters in the area.
Unscheduled COPD hospital admissions in the central area of Asturias were registered, geocoded, and grouped by census tracts (CTs), age, and sex. Standardized admission ratio, smoothed relative risk, posterior risk probability, and spatial clusters between relative risks throughout the study area were calculated and mapped.
The spatial distribution of COPD hospital admissions differed between men and women. For men, high-risk values were located primarily in the northwestern area of the study, whereas for women the cluster pattern was not as clear and high-risk CTs also reached central and southern areas. In both men and women, the north-northwest area included the majority of CTs with high-risk values.
The present study showed the existence of a spatial distribution pattern of unscheduled COPD hospital admissions in the central area of Asturias that was more pronounced for men than for women. This study could provide a starting point for generating knowledge about COPD epidemiology in Asturias.
慢性阻塞性肺疾病（COPD）是全球主要死亡原因之一，发病率也很高，在过去几十年中，COPD 的全球负担持续上升。众所周知的 COPD 危险因素包括烟草烟雾和空气污染，但遗传、年龄、性别和社会经济地位也是其他因素。本研究旨在评估 2016-2018 年阿斯图里亚斯中心地区男女 COPD 非计划性住院的空间分布，并确定该地区的趋势、空间模式或集群。
登记、地理编码并按普查区（CT）、年龄和性别对阿斯图里亚斯中心地区的非计划性 COPD 住院进行分组。计算并绘制了整个研究区域内标准入院率、平滑相对风险、后验风险概率和相对风险之间的空间集群。
男女 COPD 住院的空间分布不同。对于男性，高风险值主要位于研究的西北部地区，而对于女性，集群模式则不那么明显，高风险 CT 也延伸到了中心和南部地区。在男性和女性中，西北-西北区域包含了大部分高风险值的 CT。
本研究表明，阿斯图里亚斯中心地区存在 COPD 非计划性住院的空间分布模式，男性比女性更为明显。这项研究可以为阿斯图里亚斯 COPD 流行病学的研究提供一个起点。
