This cross-sectional study aimed to compare access to the nearest food stores with perceived access associated with intake frequencies of vegetables/fruits and meat/fish among older Japanese people. We used intake frequencies of vegetables/fruits and meat/fish from a self-administered questionnaire in the Japan Gerontological Evaluation Study among 83,384 adults aged over 65 years. We defined distance over 1 km as poor objective access in community level. We performed multilevel regression analysis to investigate the association of objective and perceived access with intake frequencies of vegetables/fruits and meat/fish, respectively. Participants who lived in poor objective access had a significantly higher intake frequency of vegetables/fruits than those who lived in good access. In contrast, residents with poor perceived access consumed lower frequent intake of vegetables/fruits (beta coefficient (standard error) 0.086 (0.021) for objective access; -0.093 (0.009) for perceived access). There was no significant association between objective access and intake frequency of meat/fish, but poor perceived access showed a significant association with lower intake frequency of meat/fish. There was inconsistency between objective and perceived measurement of access to food stores associated with dietary habits among older Japanese adults. Food access needs to be comprehensively assessed, while considering characteristics of measurements.
本横断面研究旨在比较日本老年人获取最近食品店的情况与感知获取情况与蔬菜/水果和肉类/鱼类摄入频率之间的关系。我们使用了来自日本老年人综合评估研究中 83384 名 65 岁以上成年人自我报告的蔬菜/水果和肉类/鱼类摄入频率的数据。我们将社区层面上距离超过 1 公里定义为客观获取较差。我们进行了多层次回归分析,分别研究了客观和感知获取与蔬菜/水果和肉类/鱼类摄入频率之间的关系。与居住在获取良好地区的人相比,客观获取较差的参与者蔬菜/水果摄入频率明显更高。相比之下,感知获取较差的居民蔬菜/水果摄入频率较低(客观获取的β系数(标准误差)为 0.086(0.021);感知获取的 -0.093(0.009))。客观获取与肉类/鱼类摄入频率之间没有显著关联,但感知获取较差与肉类/鱼类摄入频率较低有显著关联。在与日本老年人饮食习惯相关的食品店获取的客观和感知测量之间存在不一致性。需要综合评估食品获取情况,同时考虑测量的特点。
