Study On Prevalence And Risk Factors Of Hypertension Based On Healthy Examination People

Background and purposeHypertension is the most common cardiovascular disease and the risk factor of stoke and heart disease. It has become a major life-threaten disease in the world. The study on nutrition and health condition for 270,000 people in 2002 which conducted by The Ministry of Health show that the prevalence of hypertension is 18.8%.The result of previous study show that the crude prevalence of hypertension in Guangxi was 17.9%,the standardized prevalence rate was 15.3%,so we estimated more than 5.0797 million people have got hypertension which 1.3846 million in urban and the others are in rural.The awareness, treatment and control rates of Guangxi are far below the national level, it means that hypertension has become a severe public healthy problem in our province. The cause of essential hypertension is not clear, some studies show that hypertension is the result of genetic and environmental factors interact for each other in long term. We choose part of the population who came to the First Affiliated Hospital of Guangxi Medical University for healthy physical examination as the object, then analysis the risk factors and prevalence of hypertension according to the result of the epidemiological questionnaire, physical examination, laboratory testing, so we can provide a scientific evidence for making appropriate interventions.Objects and MethodsThe objects was part of the population who came to the First Affiliated Hospital of Guangxi Medical University for healthy physical examination. the unified questionnaire was used in this study, the content concluded questionnaire survey(including the sociological data, family history, lifestyle and behavior, etc.), physical examination (blood pressure, height, weight, waist measurements) and laboratory tests (blood glucose, total cholesterol, triglyceride, high-density lipoprotein, low-density lipoprotein test). We using SPSS 13.0 to analysis the statistics. The methods including description, T test, chi-square (x2) test, single-factor analysis, multiple logistic regression etc..Results1816 persons were taking part in this survey, 478 had get hypertension, the crude prevalence rate of 26.3%, standardized prevalence rate was 22.9% (we use the population composition of Guangxi Zhuang Autonomous Region in 2000); male and female crude prevalence rates were 31.9% and 18.4%, standardized prevalence rates were 26.5% and 17.6%; male and female prevalence difference was significant (X2trend= 41.693, P= 0.000), male than in female; the total prevalence were increased when people getting old, the chi-square test show that X2trend= 368.018, P= 0.000;The relationship between education and blood pressure was negative correlation. Prevalence of hypertension was decreased as education level was high (X2trend= 61.091, P= 0.000), the prevalence of the population who did not receive formal education is the highest (71.43%), then prevalence of the people who had receive the primary education was 7.45%, then prevalence of the people who had receive the university education was just 13.46%; the hypertension prevalence gradually increased when the body mass index increased, (x2 trend= 231.708, P= 0.000), the prevalence of normal weight were 14.55%,the prevalence of those who suffer from overweight disease were 37.70%, and the prevalence of the obesity person wre 63.41%; different people have different prevalence by the gender, ethnicity, nature of work, units, marital status, family history, smoking, alcohol consumption, blood sugar, cholesterol, triglycerides, high density lipoprotein, low-density lipoprotein, waist circumference,etc. According to the results of analysis, we have found seven risk factors the are gender, age, education level, past history, family history of hypertension, triglycerides, and BMI index. And female, the high level of education is a protective factor, male, have past history, family history of hypertension, high triglycerides, high BMI index are the risk factors. We choose the seven factors to the logistic stepwise regression model. The results showed that the sex, age, education level, past history, triglycerides, and BMI index are the independent factor for hypertension. Conclusionthe crude prevalence rate of this population is 26.3%, standardized prevalence rate was 22.9%, higher than the national level; male prevalence rate is higher than females; all the people prevalence rate of hypertension increases with age; from the prevalence rising curve, the prevalence rat have a sharp rise after 25-year-old, male, old people, low education level, past history, family history, high triglycerides, and highBMI are the risk factors of hypertension...
