Aspell N, et al. - Utilizing data from Wave 6 of the English Longitudinal Study of Aging, researchers examined the link between impaired muscle function and serum vitamin D status in community-dwelling older adults (aged ≥ 60 years). They also assessed falls as a secondary goal. Participants were 4,157 in total with a mean age of 69.8 (SD 6.9). They measured muscle strength by assessing handgrip strength and physical function by evaluating the short physical performance battery. They evaluated serum 25-hydroxyvitamin D with level < 30 nmol/L categorized as vitamin D deficient. Findings revealed the link of vitamin D deficiency with impaired muscle strength and performance among the participants. Skeletal muscle function in ageing may be prevented by reversing vitamin D deficiency at the < 30 nmol/L cut-off. There was no link between single or multiple falls and vitamin D status.
