Abstract

<p>Objective: This study aimed at investigating the relationship between neighborhood food environment and protein intake to promote prevention of long-term care at the community level in mountainous areas.</p><p>Methods: This cross-sectional study included 942 elderly people living in a mountainous region. The distance from the participant's home to the nearest supermarket and convenience store was calculated using geographic information system. The association between distance and low protein intake, based on a brief-type self-administered diet history questionnaire, was analyzed by multivariate regression analysis. Further, access to the train station and bus stops was examined as an environmental factor related to mobility in daily life. The association between distance to supermarket and convenience store with intake of each major protein source food group was analyzed as a secondary outcome.</p><p>Results: While there was no significant relationship between distance to the nearest supermarket and protein intake, a significant tendency was observed between low protein intake and longer distance to the nearest convenience store. The absence of bus stops within 400 m was significantly associated with low protein intake. There was no significant association between distance to supermarkets and convenience stores and intake of each major protein source.</p><p>Conclusions: Although the distance to the nearest supermarket was not associated with protein intake, longer distances to the nearest convenience store and poorer access to bus stops were associated with low protein intake. A dietary improvement approach that takes into account accessibility of convenience stores and bus stops may be important to promote protein intake in mountainous regions.</p>
