Abstract
Purpose:
Forests have positive effects on health due to phytoncide, thus increasing physical activity and stress relief. However, research has not been conducted on the daily health benefits of existing forests. Therefore, this study attempts to compare the health status and behaviors of residents in urban and forested areas. Methods: This cross-sectional study used anthropometric measures, blood tests, heart rate variability, depression, stress, and health behavior self-reports for adults between 35 and 79 years from two regions. Results: Adults living in a forested region had better health consequences-including lower prevalence of osteoarthritis (6.4%) and mean bone mineral density (-0.84) -than those in an urban region (osteoarthritis: 13.7%; bone mineral density: -1.55). The percentage of ‘physically active’ participants (measured in MET-minutes) differed significantly different between the forested (49.1%) and urban (7.3%) areas. However, health behaviors such as smoking, alcohol consumption, and regular heath check-up rates were worse among residents from the forested, than the urban area. Conclusion: We concluded that more proactive forest therapy programs are needed to prove the health differences.
