Objective To determine the relationship between the death of type 2 diabetes patients and the diseases of respiratory and digestive system. Methods The database of investigation of death cause in inpatients of diabetes in 15 provinces from 1991 to 2005 was analyzed for determining the diseases of respiratory and digestive system as cause of death based on ICD-10. Results There were 339 (11.9%) diabetic inpatients with respiratory system diseases and 206(7.2%) diabetic inpatients with digestive system diseases as major cause of death from the 2844 inpatients with type 2 diabetes who died in hospital. Pneumonia and chronic obstructive pulmonary disease were the most common cause of death in diseases of respiratory system. Cirrhosis was the most common cause of death in diseases of digestive system. The proportion of chronic obstructive pulmonary disease and cirrhosis as major cause of death was more in male than in female. As age increased, the proportion of diseases of respiratory system as major cause of death was increased while the proportion of diseases of digestive system as major cause of death was decreased. Conclusions The diseases of respiratory and digestive system are important causes of death in type 2 diabetic patients.%研究T2DM患者死亡与呼吸系统和消化系统疾病之间的关系.通过分析十五省市1991至2005年住院患者中伴有T2DM的死亡患者病历,调查根据ICD-10确定主要死因为呼吸系统和消化系统疾病患者的情况. 结果 共2844例住院合并T2DM的死亡患者中有339例(11.9％)主要死亡原因为呼吸系统疾病,206例(7.2％)主要死亡原因为消化系统疾病.肺炎和慢性阻塞性肺病是最主要的呼吸系统疾病死因.肝硬化是最主要的消化系统疾病死因.男性慢性阻塞性肺病和肝硬化在死因中所占比例要高于女性.随着年龄增加,呼吸系统疾病在死因中所占比例增加,而消化系统疾病所占比例减少. 结论 呼吸系统和消化系统疾病是T2DM患者重要死因.
