Low vitamin D boosts depression risk in seniors Health Reuters
However it remains unclear if these abnormalities are a author or a consequence of depression, Dr. Witte J. G. Hoogendijk and colleagues from Vrije Universiteit in Amsterdam say. Gone studies hold linked altered levels of vitamin D and parathyroid hormone with depression, on the other hand the consociation "has never been studied systematically," Hoogendijk and colleagues note.
Almost 40 percent of the men and 57 percent of women had low levels of vitamin D in their blood. Among the 169 bodies erect by self-report and diagnostic interviews to be suffering from kid depression, as blooming as the 26 with elder depressive disorder, vitamin D levels were 14 percent lower than for citizens who were unpaid from depression, the researchers found.
And blood levels of parathyroid hormone, which enlargement with vitamin D deficiency, were 5 percent higher in tribe with youngster depression and 33 percent higher in those with better depression, relative to levels seen in seniors without depression. There are a character of believable ways that low vitamin D levels could dominion mood, the researchers note, inured that the vitamin plays a role in diverse neurological and hormonal processes.
Provided vitamin D deficiency is a doer rather than a backwash of depression, they add, this suggests supplementation with the vitamin and increased exposure to sunlight could assist treat the temper disorder. Long-term studies with repeated assessments are needed to examine the catechism of whether decreased vitamin D levels and increased parathyroid hormone levels precede depression or come from it, the researchers conclude.
