Remember that movie with Billy Crystal and Robert De Niro, Analyze This? Well we all don't have super-risky mobster lifestyles to induce depression like Paul Vitti's, but according to a new study of depressed type 2 diabetics -- depression has a negative impact on blood sugar control.

Researchers treated 93 patients with type 2 diabetes and depression with the antidepressant bupropion (Wellbutrin). They chose the drug because it is capable of reducing depression and weight simultaneously. The hypothesis behind the treatment was mood enhancement and weight reduction would, in fact, improve blood sugar control. (Always a gold star day in my book!) The results were documented in the March issue of Diabetes Care, and showed that antidepressant treatment produced benefits beyond just mood improvement. Patients also lost weight, improved self-management of their diabetes, and improved their A1c levels.

In the 6 months following the conclusion of the study, depression improvement predicted maintenance of improved blood sugar control. This confirms the research hypothesis that depression improvement can produce better blood sugar control, independent of weight loss and overall diabetes management. The importance of weight-independent physiological factors like insulin sensitivity and inflammation improve during depression relief and contribute to better long-term control of diabetes.

The moral of this story? You tell me. I spotlight the research - I like it when you guys give me answers.
