Vitamin D Deficiency Associated With Increased Risk of Disability
Approximately 250 million people aged 60 years and over experience moderate to severe disability. A recent study has found that vitamin D deficiency is associated with an increased risk of disability in basic activities of daily living.
Participants in the study included 4,814 people over the age of 50 who took part in the English Longitudinal Study of Ageing. All were free of disability at the beginning of the study. Vitamin D levels were measured at baseline and participants were followed for an average of 4 years. The Basic Activities of Daily Living index was used to evaluate incidences of disability at baseline, year 2, and year 4.
Vitamin D deficiency was found to significantly increase the risk of incidence of disability in basic activities of daily living. Men with vitamin D deficiency had a 44% higher risk of developing disability compared to men with sufficient vitamin D levels. Women with vitamin D deficiency had a 53% higher risk of developing disability compared to women with sufficient vitamin D levels.
The study was conducted by researchers from the Federal University of San Carlos.It was published on November 11, 2020 in The Journal of Nutrition.
