| Outline of Final Research Achievements |
In the present study, we aimed to examine prospective association between daily physical activity and chronic pain from the point of view of epigenetics and inflammatory process. Herewith, we sought to clarify the mechanisms of pain relief by physical activity.
Community-dwelling older adults were enrolled in this study and physical activity, pain condition, inflammatory cytokine levels, and micro RNA expression were measured in baseline and follow-up. In longitudinal analysis, participants with chronic pain showed decreased daily walking time and increased sedentary time. According to micro RNA profiling related to change of chronic pain, expression levels of some micro RNAs that could affect chronic inflammation were significantly altered.

| Academic Significance and Societal Importance of the Research Achievements |
慢性疼痛に対する非薬物療法として身体運動は国際的に推奨されているものの、なぜ身体運動が疼痛緩和に繋がるのかについては未だ十分に明らかにされていない。本研究結果は、身体運動と疼痛緩和との間に存在するメカニズムの解明において、新たな側面からのアプローチとして有用な知見を提供するものと考えられる。
