Lack of Vitamin D associated with greater risk of depression

Older adults with Vitamin D deficiency are at greater risk of developing depression, finds a study. The study has been published in Journal of Post-Acute and Long-Term Care Medicine (JAMDA). A new study by researchers from The Irish Longitudinal Study on Ageing (TILDA) at Trinity College Dublin has shown for the first time in Ireland that a deficiency in vitamin D was associated with a substantial increased risk of depression (+75 percent) over a four-year follow up period. Later life depression can significantly reduce quality of life and is a potent risk factor for functional decline, admission to residential care and early death. Given the complex nature of depression, including the fact that the majority of older adults are undiagnosed, prevention is a priority and the identification of important risk factors is crucial.
