There is increasing evidence that vitamin D status is associated with muscle function. Vitamin D deficiency is common in immigrants. We hypothesized that there was a positive association between vitamin D status and muscle strength in immigrants. ⋯ In multivariable analyses, reduced lower limb muscle strength remained linearly associated with lower 25(OH)D concentrations (P = .008) and weaker grip strength remained associated with vitamin D deficiency (P = .022) after adjustments. The association between vitamin D deficiency and reduced lower limb muscle strength did not reach statistical significance (P = .052). The results demonstrate that vitamin D deficiency and low 25(OH)D concentrations were associated with muscle weakness in immigrants.
