ObjectiveTo explore the prevalence and risk factors of hypertension in Anyue County from June 2011 to June 2013.
MethodsUsing stratfied random cluster sampling method, 5 391 people over 15 years of age were selected from 3 residential areas and 3 natural villages to finish a questionnaire and blood pressure measurement.
ResultsThe total prevalence rate of hypertension in Anyue County was 18.77%. The prevalence rates of hypertension in urban areas and rural areas were 21.75% and 16.20%, and the difference was significant (χ2=27.120, P<0.001). In both urban and rural areas, the prevalence rate of hypertension increased with age (χ2=475.634, P<0.001; χ2=394.026, P<0.001). The percentages of awareness, treatment and control in Anyue County were 31.30%, 24.41%, and 9.09%. The percentages of awareness, treatment and control in urban areas were 40.15%, 33.70%, and 11.23% and were 20.68%, 13.65%, and 6.61% in rural areas. There were significant differences in the percentages of awareness, treatment and control between urban and rural areas (χ2=44.475, P<0.001; χ2=54.861, P<0.001; χ2=8.202, P=0.004). The logistic regression analysis showed that age (OR=1.061, P<0.001), diabetes (OR=1.550, P<0.001), hyperlipemia (OR=2.372, P<0.001) and smoking (OR=1.335, P<0.001) were the risk factors for hypertension; and it showed that high level of education was a protective factor for hypertension (OR=0.755, P<0.001).
ConclusionBecause of high prevalence and low percentages of awareness, treatment and control in Anyue County, the prevention and control situation of hypertension are grim. We should focus on the control of smoking, blood lipid and blood glucose.
