Not Just Bones, Vitamin D Deficiency May Also Weaken Your Muscles
Vitamin D deficiency increased the likelihood of poor skeletal muscle function in older adults, says study.
Vitamin D deficiency may lead to poor skeletal muscle function in adults aged 60 years and over, suggests new research.
Maintaining skeletal muscle function throughout life is a crucial component of successful ageing, in promoting independence, mobility, quality of life and reducing falls and frailty.
While resistance exercise is known to preserve muscle function, there is growing evidence that adequate vitamin D status may also be protective.
“Our results show that vitamin D deficiency increased the likelihood of poor muscle function in older adults and confirms the protective effect of physical activity.”Maria O’Sullivan, Study author and Associate Professor in Nutrition at Trinity College Dublin, Ireland
"Maintaining muscle function is incredibly important, and often overlooked, in promoting healthy ageing. Addressing this through multimodal approaches that incorporate physical activity, reversing vitamin D deficiency and other modifiable diet and lifestyle components require further investigation," O'Sullivan said.
The findings are based on the analysis of data from over 4,000 adults aged 60 years and over, from the English Longitudinal Study of Aging (ELSA).
The prevalence of muscle weakness was twice as high among older adults with vitamin D deficiency compared with vitamin D adequacy, showed the findings published in the international journal Clinical Interventions in Ageing.
Similarly, impaired "muscle performance" was three times higher in older adults with vitamin D deficiency compared with vitamin D adequacy.
Based on more complex statistical analysis, the study showed that vitamin D deficiency significantly increased the likelihood of impaired muscle strength and performance.
The study confirmed the associated benefits of physical activity. Older adults partaking in regular moderate physical activity had significantly lower likelihood of poor muscle strength and physical performance.
