A just-released three-year study finds type 2 diabetes¹ and depression can be a fatal mix.

Researchers found patients whose type 2 diabetes was accompanied by minor² or major depression had higher mortality rates, compared with patients with type 2 diabetes alone.

Researchers at the University of Washington and at Group Health Cooperative, a large, Seattle-based health plan, surveyed and then followed 4,154 patients with type 2 diabetes. The patients completed written questionnaires and then automated³ diagnostic, laboratory, and pharmacy⁴ data were collected from the HMO.

The researchers also reviewed Washington state mortality data to analyze⁵ diabetes complications and deaths. They found depression is common among people who have type 2 diabetes and is strongly linked with increased mortality.

But the researchers said more work is needed to untangle the cause-and-effect relationships among depression, behavior, diabetes complications and mortality.

The results appear in the November edition of Diabetes Care, published by the American Diabetes Association.

　　日前公布的美国一项医学研究结果显示，同时患有2型糖尿病和抑郁症的患者可能会面临更大的生命危险。

　　据合众社10月26日援引最新一期美国《糖尿病护理》杂志的报道说，华盛顿大学及“健康合作计划”的研究人员最近发现，那些同时患有2型糖尿病和轻度或重度抑郁症的人的死亡率要更高一些。

　　研究人员发现，抑郁症在2型糖尿病患者中比较普遍，并与死亡率的增加有着很大的联系。

　　研究人员是在对4154名2型糖尿病患者进行了3年跟踪调查和研究，并统计了华盛顿州的死亡率数据之后得出这一结论的。但研究人员同时表示，他们还需要进行更为深入的研究以解开抑郁症、患者行为、糖尿病并发症以及死亡率之间的因果关系。
