Abstract
Background
Physical inactivity is one of the global health concerns. Rural populations in general tend to be more physically inactive and have higher risk for chronic conditions. Although numerous studies have assessed the association between neighborhood environment and physical activity to implement population level intervention, most are limited to urban adults. This study investigated potential neighborhood environment associated with physical activity for rural older adults in Japan.
Methods
The study subjects were from Shimane where is a rural-mountainous region in Japan. Those agreed to participate in the Shimane CoHRE study as of baseline (2010) and followed-up after 5 years were included in the analysis (mean age=71, n = 717). Subjects were asked if they engage in 30 minutes exercise more than twice a week at baseline and follow-up surveys. As a primary exposure, we computed mean land slope within 500 m street network buffer from residential point of each subject by geographic information system. Multiple logistic regression was conducted to estimate the odds of exercise engagement after 5 years by slope categorized in tertile, adjusting for age, BMI, and exercise habit at baseline.
Results
Significantly higher odds of exercise engagement was observed among those living in the hilly area compared to moderately hilly area after 5 years adjusting for baseline age, BMI, and exercise habit, (Odds ratio (OR): 1.71, 95% Confidence Interval (95%CI): 1.119, 2.616). There was no significant difference of odds between those in flat area and moderately hilly area (OR: 1.137, 95%CI: 0.738, 1.751).
Conclusions
This finding suggests that people living in hilly neighborhoods are more likely to maintain or start engaging in exercise after 5 years. Considering other potential environmental factors and farming culture within rural areas, future studies should capture various forms of environmental components and physical activity to dissect the mechanism.
Key messages
There are limited studies focus on rural older adults. Unique geographic feature in rural areas, i.e. hilly neighborhood might be associated with physical activity.
