AbstractPhysical activity is crucial to prevent sarcopenia, but there is scant data on the link between sarcopenia and physical activity in rural communities. Therefore, this study investigated associations of farming activity and snow removal with sarcopenia in a middle-aged and older population in rural Japan. This cross-sectional study enrolled 3,056 residents aged ≥ 40 years (49.2% men; mean age, 64.2 years) in Yuzawa, Japan. Information on farming activity and snow removal were collected via questionnaire from May through November and from December through April, respectively. Sarcopenia was assessed by the SARC-F (strength, ambulation, rising from a chair, stair climbing, and history of falling) score. Associations of farming activity and snow removal with sarcopenia were assessed using multivariable logistic regression analysis with adjustment for potential confounders. Participants who engaged in farming activity, snow removal, and both accounted for 3.8%, 40.5%, and 29.4% of the total, respectively. In the multivariable logistic regression analysis, adjusted odds ratios [95% confidence intervals (CI)] of sarcopenia for farming activity and snow removal were 0.80 (0.63-1.03) and 0.68 (0.53-0.87), respectively. Compared with participants who did not engage in farming activity or snow removal, participants who engaged in both had a significantly lower adjusted odds ratio of sarcopenia [0.63 (95% CI 0.47-0.86)]. Participants who engaged in snow removal and those who engaged in both farming activity and snow removal showed inverse associations with sarcopenia. Our findings further support the importance of physical activity in preventing or mitigating sarcopenia in rural communities.
