Besides, the prevalence rates of hypertension in urban and rural areas were 33.8% and 36.6% respectively. There was no significant difference between the prevalence rates in urban areas (33.8%) and that in rural areas (36.6%) (χ2=1.46,P=0.227). The prevalence rate of hypertension increased with age (χ_trend2=127.20,P<0.001). The prevalence rate in male was higher than that in female(χ2=8.22,P=0.004). Multivariate Logistic regression analysis results showed that sex, older than 45 years, family history of hypertension, overweight, obesity and central obesity were risk factors of hypertension. Conclusions The prevalence of hypertension among residents over 15 years old in urban and rural areas of Hefei was high.Targeted prevention and control measures should be developed according to the disease characteristics of the city.
