Objective: To analyze the prevalence and risk factors of hypertension combined with diabetes in the middle to elder population in the Nan'an district of Chongqing, and to provide evidence for formulating relevant prevention and control strategies. Methods: Middle or elder adults were enrolled by a Stratified multistage cluster sampling method. Questionnaire survey and the related measurements were conducted. The epidemiology of hypertension combined with diabetes was analyzed descriptively, and the risk or protective factors were analyzed by logistic regression method. Results: A total of 24 792 people were surveyed, with 1 547 patients identified as having hypertension combined with diabetes. The overall prevalence rate appeared as 6.2%, of which 6.0% in males and 6.4% in females, respectively. The prevalence of hypertension combined with diabetes in the general population was increasing with age (χ(2)=343.766, P<0.001). Factors as age, education, smoking, marital status, exercise, BMI, triglyceride, total cholesterol, high density lipoprotein cholesterol and low density lipoprotein cholesterol were related to the prevalence of hypertension and diabetes. High density lipoprotein cholesterol appeared as a protective factor for hypertension combined with diabetes (OR=0.817, 95%CI: 0.715-0.934). Age, education, low density lipoprotein cholesterol and lack of exercise all appeared as risk factors for hypertension combined with diabetes (P<0.05), respectively. Conclusions: The prevalence rate of hypertension combined with diabetes in the middle or elder adults in Nan'an of Chongqing seemed high. Attention should be paid to the health status of people being elderly, overweight or obese, low cultural level, smoking, triglyceride abnormality, total cholesterol abnormality and high low density lipoprotein cholesterol, so as to reduce the risk on hypertension combined with diabetes.
目的： 了解重庆市南岸区中老年人高血压合并糖尿病的患病情况及相关影响因素，为有针对性地制定防治策略及措施提供科学依据。 方法： 采用分层多阶段整群抽样方法，选取≥40岁人群进行患病情况问卷调查和相关指标检测，采用描述性流行病学方法分析高血压合并糖尿病患病情况，应用logistic回归分析高血压合并糖尿病患者的危险因素和保护因素。 结果： 共调查24 792人，检出高血压合并糖尿病患者1 547人，患病率为6.2%。其中男性患病率为6.0%，女性患病率为6.4%，趋势性χ(2)检验结果显示总人群中高血压合并糖尿病的患病率随年龄增加呈上升趋势（趋势性χ(2)=343.766，P<0.001）。患者年龄、文化程度、吸烟、婚姻状况、缺乏锻炼、BMI、TG、TC、HDL-C、LDL-C等均为高血压合并糖尿病的相关影响因素。HDL-C偏高为高血压合并糖尿病的保护性因素（OR=0.817，95%CI：0.715~0.934）；年龄、文化程度、LDL-C偏高、缺乏锻炼等均为高血压合并糖尿病的危险因素（P<0.05）。 结论： 重庆市南岸区中老年人的高血压合并糖尿病患病率较高，今后应重视对高龄、超重或肥胖、文化程度较低、吸烟、TG、TC异常、LDL-C偏高居民的健康干预，以降低高血压合并糖尿病的患病风险。.
