Outline of Final Research Achievements |
In recent years, vitamin D has been known to affect skeletal muscle. Vitamin D deficiency is frequent in our country. We examined the association of vitamin D with the appendicular skeletal muscle index (SMI), grip strength, and walking speed in a cohort study of community-dwelling older people. In the 70s, vitamin D was significantly associated with SMI and grip strength. SMI was also associated with vitamin D after adjustment for sex, BMI, and serum albumin. In the 90s, vitamin D was significantly associated with SMI and grip strength. However, SMI was not independently associated with vitamin D in multivariate regression analysis. The results indicate that maintaining vitamin D levels may contribute to maintaining skeletal muscle mass.

Academic Significance and Societal Importance of the Research Achievements |
ビタミンDは一般的に骨代謝を改善することが知られている。本研究により、ビタミンDは骨のみならず筋にも影響していることが明らかになった。加齢に伴う骨格筋減少症であるサルコペニアに対しては、未だ有効な介入方法が明らかになっていない。本研究の結果は、サルコペニアに対して、ビタミンDを維持することが有効である可能性を示すものであり、ビタミンDの補充は、サルコペニアの治療法の候補となりうる。
