Objective To compare the prevalence and influencing factors of hypertension among the elderly in urban and rural areas of Kunming municipality, Yunnan province and to provide references for developing hypertension prevention and control measures for the two groups of population.
Methods We selected 3 225 residents at ages of 60 years and above in 6 communities of an urban district and 6 rural villages in a county of Kunming municipality of Yunnan province using stratified multistage random sampling; then a face-to-face questionnaire survey and physical examination were conducted among the elderly from July 2016 to October 2017.
Results The prevalence of hypertension among the 1 624 urban and the 1 601 rural elderly were 40.9% and 43.5%, and the standardized hypertension prevalence for the two groups were 41.3% and 43.2%, respectively, with no significant difference in the hypertension prevalence between the urban and rural elderly (P > 0.05). The results of multivariate unconditional logistic regression analysis demonstrated that alcohol drinking and overweight/obesity were risk factors of hypertension among the urban elderly; whereas, among the rural elderly, aged over 75 years, lack of physical activity, overweight/obesity, and central obesity were risk factors of hypertension and smoking was a protective factor against hypertension.
Conclusion Hypertension prevalence is not significantly different but the distribution for the influencing factors of hypertension is significantly different between the elderly in urban and rural region of Kunming city. The results suggest that targeted prevention and control measures for hypertension should be developed according to characteristics of the urban and rural elderly population.
