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.
