ABSTRACT
CONTEXT Vitamin D is a steroid hormone that acts by binding to the vitamin D receptor (VDR) found in many tissues. According to the long-term mechanism, vitamin D causes the proliferation and differentiation of muscle cells by gene transcription. OBJECTIVE:
We aimed to evaluate the relationship between muscle strength and serum vitamin D levels in elderly men.DESIGN:
Cross-sectional study. SUBJECTS ANDMETHODS:
Male patients over age 50 were included in the study. Study population was divided into 2 groups with handgrip strength according to body mass index, either as subjects with weak or with normal handgrip strength test (HGST). Vitamin D levels and other variables compared between weak and normal groups.RESULTS:
Vitamin D level of weak and normal groups were 7.5 (3-19.9) µg/L, and 11.6 (11.6-34.9) µg/L, which means significant reduced vitamin D levels in weakness group (p=0.01). Vitamin D levels were significantly correlated with HGST levels (r0.362, p=0.001). Vitamin D levels were found to be an independent predictor of weakness according to HGST in logistic regression analysis (OR 0.453, 95% Cl0.138-0.769, p=0.05).CONCLUSIONS:
Low vitamin D level is an independent risk factor for muscle weakness in men aged more than 50 years. Therefore, vitamin D levels should be screened and early replacement should be initiated for the sake of improvement of muscle strength in elderly subjects that vulnerable for frailty.
