This study aimed to investigate the effect of blood vitamin D levels and dietary patterns on sarcopenia among community-dwelling people enrolled the Dynamics of lifestyle and Neighborhood Community (DOSANCO) on Health Study.
The serum 25-hydroxyvitamin D levels in participants was 24.8 ng/mL for males and 22.5 ng/mL for females. Three dietary patterns were identified from the results of factor analysis: vegetable, traditional Japanese, and low-confectionery. The higher vitamin D levels was significantly associated with the higher muscle strength. However, regarding three dietary patterns, no significant associations were observed with muscle mass, muscular strength, and sarcopenia.
This study is limited to cross-sectional study. Further study is needed that follow-up of participants and investigate to effect of vitamin D levels and dietary patterns on the long-term care and mortality.
