Research published in the Journal of Clinical Endocrinology & Metabolism reports that vitamin D deficiency is associated with frailty and all-cause mortality in older men.
The researchers, led by Yuen Wong, MBBS, were interested in examining the relationship between D deficiency, frailty and mortality in older men living in Australia.
The study included data from 4,200 men aged 70-88 years who were enrolled in the Health and Men cohort. This cohort began in 1996 and enrollees were followed through 2009. At baseline, the researchers looked at these men’s frailty scores and how and if they correlated with vitamin D levels at all. Frailty was assessed by the FRAIL scale which measures fatigue, resistance, ambulation, illness, and loss of weight. They also wanted to know if vitamin D levels and/or frailty were associated with mortality risk at all over the course of the 13 year study period.
