Objective To understand the prevalence and influencing factors of hypertension among the elderly aged 60 years and above in Mianyang City,Sichuan Province,so as to provide clues for targeted prevention and control of hypertension. Methods A total of 115 775 permanent residents aged 60 and above screened out from Mianyang demonstration sites from October 2017 to April 2019 were investigated by questionnaire and physical examination,and the data of personal basic information,lifestyle,body height,body weight,waist circumference,and blood pressure were collected.SPSS 22.0 was used for descriptive analysis,single factor analysis,and Logistic regression analysis. Results The prevalence rate of hypertension in the elderly aged 60 years and above in Mianyang was 50.60%.Specifically,the prevalence rates of hypertension in men and women were 50.27% and 50.85%,respectively.The prevalence rate of hypertension increased with the increase in age([Formula: see text]=370.199,<0001).Multivariate Logistic regression analysis showed that the independent risk factors of hypertension included age of 70-79 years(=1.327,95%=1.292-1.363,<0.001),the age of 80 years and above(=1.455,95%=1.386-1.527,<0.001),widowhood(=1.343,95%=1.296-1.392,<0.001),divorce(=1.255,95%=1.033-1.525,=0.022),overweight(=1.431,95%=1.391-1.473,<0.001),obesity(=2.171,95%=2.076-2.270,<0.001),waist-to-height ratio>0.5(=1.317,95%=1.281-1.354,<0.001),history of diabetes(=1.865,95%=1.791-1.941,<0.001),history of smoking(=1.107,95%=1.068-1.148,<0.001),and history of drinking(=1.950,95%=1.894-2.009,<0.001).Living in urban-rural fringe areas(=0.628,95%=0.594-0.664,<0.001),education background of junior high school and above(=0.942,95%=0.912-0.974,<0.001),and low body weight(=0.785,95%=0.742-0.830,<0.001) were protective factors for hypertension. Conclusions More than 50% of the elderly aged 60 years and above in Mianyang suffer from hypertension.The elderly with advanced age,widowhood,divorce,overweight,obesity,waist-to-height ratio>0.5,diabetes history,smoking history,and drinking history are the high-risk groups of hypertension.
