In studying the association between antidepressant use, diagnosed depression, and new-onset diabetes among elderly Medicare beneficiaries, researchers found Medicare beneficiaries with any depression were twice as likely as those without depression to develop diabetes.
Depression independently increased the risk of developing diabetes in the Medicare population, although there was no evidence of an association between antidepressant use and new-onset diabetes.
If replicated, say researchers, these results have significant clinical implications.
