PREVALENCE AND DETERMINANTS OF HYPERTENSION AMONG ADULT RESIDENTS IN A GANSU PROVINCE

[Objective]To study the prevalence of hypertension in different level and the risk factors of hypertension among adult residents in Gansu province.[Methods]6 672 adult residents over 35 years old were selected by multistage stratified random sampling,and investigated with questionnaires,physical examination and cardiovascular examination from 2004 to 2007. The univariate chi-square test and multivariate conditional logistic regression were used to analyze hypertension with SPSS 17.0 software.[Results]The univariate analysis indicated that the prevalence of hypertension was 19.0%,11.8% and 6.4% for grade 1,2 and 3 hypertention respectively which increased with age rising,except 55 age group in grade 3. The standardized rate of hypertension was 36.1%,36.0% in men and 36.9% in women. The prevalence of hypertension was more severe in men than woman for grade 1,2(P﹤0.01),and in cities than countries for grade 1,2,3(P﹤0.01),and related with obesity and central obesity but in obesity was higher than in central obesity(P﹤0.01). The multiple logistic regression analysis indicated that the risk factors of hypertension in residents were the peasantry,age,the history of hypertension,seafood,pulse,overweight and obese,central obesity,BV(blood viscosity),cardiac output,except pulse was the protective factor.[Conclusion]The residents should improve the conscious of self health care,and form good live style habits and individual behavior,especially weight loss.
