鉴于农村地区的公共交通网络往往比城市地区差，不开车的农村居民很难获得促进健康的商品、服务和与咀嚼能力有关的资源。此外，通过海拔评估的地理位置可以改变这种关联。本研究的目的是测试交通工具和咀嚼能力之间的关联是否因海拔而异。数据收集自日本瑞穗和岩见县进行的横断面研究。客观咀嚼能力进行了评估，使用测试胶冻和海拔估计的地理信息系统根据参与者的地址。排除数据缺失的受试者后，分析了672例受试者（瑞穗= 401例，岩见= 271例）。调整潜在混杂因素后，在瑞穗县居住在低海拔（≤313 m）的老年人中，驾驶员与咀嚼能力无显著相关。然而，经过同样的调整后，在高海拔地区的老年人中，驾驶员仍然与咀嚼能力的增加显著相关。在Iwami县也观察到类似的结果。在生活在高海拔地区的老年人中，可接受的运输与咀嚼能力的增加显著相关，但在低海拔地区的老年人中则不然。
Given that public transportation networks are often worse in rural areas than in urban areas, rural residents who do not drive can find it difficult to access health-promoting goods, services, and resources related to masticatory ability. Moreover, geographical location, assessed by elevation, could modify this association. The aim of this study was to test whether the association between access to transportation and masticatory ability varied by elevation. Data were collected from a cross-sectional study conducted in Mizuho and Iwami counties, Japan. Objective masticatory ability was evaluated using a test gummy jelly and elevation was estimated by the geographic information systems according to the participant’s address. After excluding subjects with missing data, 672 subjects (Mizuho = 401 and Iwami = 271) were analyzed. After adjustment for potential confounders, being a driver was not significantly associated with masticatory ability among elderly people living at low elevation (≤313 m) in Mizuho county. However, after the same adjustment, being a driver remained significantly associated with increased masticatory ability among elderly at high elevations. Similar findings were observed in Iwami county. Accessible transportation was significantly associated with increased mastication ability in elderly people living at high elevations, but not in those living at low elevations.
