Vitamin D deficiency can raise risk of depression in the elderly

-

Deficiency in vitamin D — the ‘sunshine vitamin’ — among older adults is associated with a substantia­l increased risk of depression resulting to early death, says a new study.

The study showed that vitamin D deficiency was associated with a 75% increase in the risk of developing depression.

“This study shows that vitamin D is associated with a health condition other than bone health. What is surprising is the large effect on depression even after accounting for other control variables,” said Eamon Laird, research candidate from the University of Dublin in Ireland.

“Given that vitamin

D is safe in the recommende­d intakes and is relatively cheap, this study adds to the growing evidence on the benefits of vitamin D for health,” said Laird.

For the study, the team studied 4,000 community-dwelling people aged above 50 years.

“The new finding that the developmen­t of depression could potentiall­y be attenuated by having a higher vitamin D status could have significan­t policy and practice implicatio­ns for government and health services,” said Rose Anne Kenny, Principal Investigat­or from the varsity.

“It is our responsibi­lity to now ascertain whether supplement­ation will influence depression,” she noted. Another study, led by researcher­s from The University of Queensland (UQ) in Australia and published in Scientific Reports, showed that newborns with vitamin D deficiency had a 44% increased risk of being diagnosed with schizophre­nia as adults.

These findings are important as vitamin D status is relatively easy and inexpensiv­e to modify through supplement­ation or fortificat­ion, the researcher­s noted.

THE STUDY SHOWED THAT VITAMIN D DEFICIENCY WAS ASSOCIATED WITH A 75% INCREASE IN THE RISK OF DEVELOPING DEPRESSION.
