Objective To understand the prevalence of hypertension among residents aged 15 years and older in Feixi county,and provide evidence for further hypertension prevention and control measures. Methods A multi-stage cluster random sampling method was used to select 4 278 households in Feixi County. A total of 7 030 residents aged 15 and over were investigated. The investigation and physical examination were conducted by combining centralized and household surveys. The prevalence of hypertension and awareness of blood pressure were analyzed. Results The prevalence rate of hypertension was 22.0%,which was higher in male than that in female (χ²=7.941,P=0.005). The prevalence rate of hypertension increased with age (χ²=481.65,P=0.000) and decreased with the rise of education level (χ²=232.821,P=0.000). The prevalence rate of hypertension was statistically different among different occupations (χ²=42.274,P=0.000). The awareness rate of hypertension increased with age (χ²trend=6.366,P=0.012) and increased with the rise of education level (χ²=12.183,P=0.016). The awareness rate of hypertension was statistically different among different occupations (χ²=65.219,P=0.000). Conclusion The prevalence rate of hypertension among residents aged 15 years and above in Feixi county was relatively high,and the awareness rate of hypertension was relatively low. The county's hypertension management and health promotion should be strengthened to improve the disease control rate and high blood pressure awareness rate one,thereby reducing the risk of hypertension.
