本研究的目的是检验海拔高度与农村山区老年居民认知功能之间是否存在关联。数据是2012年在位于日本岛根县南部农村山区的大南町进行的横断面研究中收集的。使用CADi（痴呆症认知评估，iPad版）评估认知功能，并根据参与者的地址使用地理信息系统估计海拔高度。排除数据缺失的受试者后，对866名参与者进行了分析。在调整了潜在的混杂因素后，较高的海拔与认知功能下降显著相关。这一发现表明，重要的是要考虑物理环境，即，海拔高度，这将影响健康促进商品，服务和资源的可及性，当寻求保持认知功能，在农村山区的老年人生活。
The aim of this study was to test whether there is an association between elevation and cognitive function among elderly residents in rural mountainous areas. Data were collected in 2012 from a cross-sectional study conducted in Ohnan Town, which is located in a rural mountainous area in the southern part of Shimane Prefecture, Japan. Cognitive function was evaluated using CADi (Cognitive Assessment for Dementia, iPad version) and elevation was estimated by using Geographic Information Systems according to the participant’s address. After excluding subjects with missing data, 866 participants were analyzed. After adjustment for potential confounding factors, higher elevation was significantly associated with decreased cognitive function. This finding suggests that it is important to consider the physical environment, i.e., elevation, that would affect accessibility to health-promoting goods, services, and resources when seeking to maintain cognitive function in elderly people living in rural mountainous areas.
