| Research Abstract |
This study aimed to determine whether there was any association between the regional climate and the proportion of people with joint pain. Regional climate data between 1971 and 2000 were obtained from the Japan Meteorological Agency. The regional proportion of people with joint pain was obtained from the National Survey for Health in 2001. We found that sunlight hours showed a direct, negative association with the proportion of people with joint pain (ΔR^2=0.532, p=0.016) in cluster 1, which was characterized as the region with the fewest total hours of sunlight, less precipitation, a modest number of rainy days, and low temperature. We concluded that the degree of exposure to sunlight may play a crucial role in prevention of joint pain. This finding should encourage people to set aside some time for staying outdoors in their daily lives.
