Minor and major depression can lead to an increase in the death rates for people with type 2 diabetes, according to researchers.

Type 2 diabetes and depression can be a fatal mix. Patients whose type 2 diabetes was accompanied by minor or major depression had higher mortality rates, compared to patients with type 2 diabetes alone, over the three-year period of a recent study in Washington state. The results appear in the November 2005 edition of Diabetes Care, published by the American Diabetes Association.

Researchers at the University of Washington (UW) and at Group Health Cooperative, a large, Seattle-based health plan, conducted the study. The researchers surveyed and followed up 4,154 patients with type 2 diabetes. The patients filled out written questionnaires. With patients' consent, automated diagnostic, laboratory, and pharmacy data were collected from the HMO. The researchers also reviewed Washington state mortality data to analyze diabetes complications and deaths.

Depression is common among people who have type 2 diabetes. This high prevalence can have unfortunate repercussions. Both minor and major depression among people with diabetes are strongly linked with increased mortality.

'Depression may be associated with increased mortality in patients with diabetes because of both behavioral and biologic factors,' the researchers noted in their article. More work, they added, is needed to untangle the cause and effect relationships among depression, behavior, diabetes complications, and mortality.

Dr. Wayne Katon, professor and vice chair of the UW Department of Psychiatry and Behavioral Sciences, led the recent study. He is a noted researcher on the associations between depression, aging, and chronic diseases, and on the medical costs and personal toll from untreated or inadequately treated depression. The research team included Drs. Carolyn Rutter, Greg Simon, Elizabeth Lin, Evette Ludman, and Michael Von Korff from the Group Health Cooperative Center for Health Studies; Dr. Paul Ciechanowski, UW assistant professor of psychiatry and behavioral sciences; Dr. Leslie Kinder from the Veterans Affairs Puget Sound Health Care System; and Dr. Bessie Young from the UW Department of Medicine.

The researchers pointed out that a sedentary lifestyle was an important, independent predictor of mortality from diabetes. Earlier studies have shown that lack of exercise and physical activity can predict depression, and, conversely, that depression can predict the development of a sedentary lifestyle. Other studies have shown that improvements in treating depression in diabetes patients can lead to the patients exercising more and to better physical functioning.
