Abstract

Objectives: Neighborhood walkability has been found to be positively related to physical activity and negatively associated with risks of noncommunicable diseases. However, limited studies have examined its association with sarcopenia in older adults. Thus, this study aimed to examine the association between neighborhood walk score and risks of sarcopenia in a sample of older Taiwanese adults. Design and setting: This study was a cross-sectional investigation using telephone-based survey. Participants: A nationwide telephone-based survey targeting older adults (≥ 65 years) was conducted in Taiwan. Measurements: Data on neighborhood walkability (determined by walk score of residential neighborhood), sarcopenia scores (measured by SARC-F), and personal characteristics were obtained. The relationships between walk score and risks of sarcopenia were examined using generalized additive models. Results: A total of 1,056 older adults participated in the survey. In model 1 (sex and age) and model 2 (full-adjusted model), a nonlinear association between neighborhood walk score and risks of sarcopenia was observed. Results showed that risks of sarcopenia appear to be lower in neighborhoods with a 40-walk score (Car-Dependent; most errands require a car) and an 80-walk score (Very Walkable) and highest in the neighborhood with a 60-walk score (Somewhat Walkable). Conclusions: The study revealed a nonlinear relationship between neighborhood walkability and risks of sarcopenia in older adults in Asian context. Results provided information to urban designers and public health practitioners that more walkable neighborhood may not necessarily protect older adults from risks of sarcopenia.
