Prevalence And Risk Factors Of Prehypertension In Rural Areas Of Jilin Province

Objective:Investigation of the prevalence of prehypertension and its related risk factors.Methods:Between July2013to August2013having extracted2612people (over the age of35)that came from four villages in Dong Feng and Jing Yu county as the object of investigation.The establishment of Epidata3.1database using the survey, measurement data using mean andstandard deviation index, count data using rate and constituent ratio index, measurement datausing single factor variance analysis, count data using chi square test and multivariate analysisusing non conditional Logistic regression analysis.All data using SPSS21.0software packagefor statistical analysis, P <0.05was considered statistically significant.Results:1. The situation is different blood among pressure-related groups1.1Demographic characteristics of different blood pressure gropsIn this survey, the normal blood pressure group is834cases (31.9%), theprehypertension group is1037(39.7%), the hypertension group is741cases (28.4%), malehypertension prevalence is higher than female（40.7%vs38.9%，P>0.05).45-55age groupand the55-65age group, the largest number of prehypertension, each constituent ratio of thenumber of blood pressure increases with age group increased year by year (P <0.001).1.2Smoking in different blood pressure crowdThe survey shows that the proportion of smokers in prehypertension and hypertensiongroup is higher, the proportion of non-smokers in normal blood pressure and prehypertensiongroup is higher. Comparison between groups have no statistical difference (P>0.05).1.3Drinking in different blood pressure groupIn the survey, the proportion of drinking is different among normal blood pressure andprehypertension group, hypertension group.The difference has statistically significance(P <0.001).1.4Drinking tea in different blood pressure groupIn the survey, the proportion of drinking tea is different among normal blood pressure and prehypertension group, hypertension group.The difference has not statistically significance(P<0.001).1.5Physical labor conditions of different blood pressure groupThe survey showed that the proportion of prehypertension is high between severe manualand non-manual workers.The difference has statistically significant (P<0.001).1.6Obesity conditions of different blood pressure groupThe survey results show that the population in prehypertension, BMI、WC and WHR arehigher than normal blood pressure groups,blood pressure in different gender groups increaseswith obesity index.1.7Fasting blood glucose of different blood pressure group.In this survey of female population, percentage of normal fasting blood glucose is highestin different blood pressure, fasting blood glucose of different composing in different bloodpressure, the difference has statistically significant (P<0.001).1.8Cholesterol levels of different blood pressure group.In this investigation, TC、TG and LDL-C levels of the prehypertensive population arehigher than normal blood pressure group, the HDL-C level is lower than the normal bloodpressure group,the difference has statistically significant between the groups (P<0.001andP<0.05).2. Analysis of prehypertension risk factors2.1Single factor analysis of prehypertensionIn the survey of male population, the group of prehypertension has more Obese peoplethan other goups. In the women surveyed, the age has different distribution among differentgroup of blood pressure, the difference was statistically significant (P <0.001).In terms ofphysical labor, the physical labor intensity focused on free working group in prehypertensioncrowd,different blood pressure has various distribution in physical labor, fasting bloodglucose level, HDL-C level and obesity index. The difference has statistically significant.2.2Multi-factor unconditioned logistic regression analysis of Prehypertension risk factors.Multivariate logistic regression results show that the waistline affect the prevalence ofprehypertension in the male respondents. In the women surveyed, the physical strength,HDL-C levels, BMI influence the prevalence of prehypertension. Great physical strength andhigh HDL-C level are protective factors of the prehypertension, high BMI is a risk factor ofprehypertension. Conclusion:The survey shows that it has a highe incidence of prehypertension among people. Age,physical activity, body mass index and BMI are risk factors of prehypertension,It has differentincidence of prehypertension and importent risk factors between fale and female. We shouldtake different lifestyle to intervene prehypertensive patients of different gender.Clinicians and patients should focus on prevention of hypertension rather than thetreatment.It is essential to identify the high risk population of prehypertension.Prehypertension is not only easy to progress hypertension, but also to influence variouscardiovascular diseases obviously. We should intervene and manage prehypertensionscientifically and reasonably. Removing the risk factors of prehypertension actively hasimportant clinical significance.
