Prevalence and risk factors of hypertension combined with diabetes in middle and elder population in Nan’an district of Chongqing / 中华流行病学杂志

ABSTRACT

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 (χ2=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.
