The Prevalence And Risk Factors For Hypertensionof Adults In Nanchang

Objective: The study aimed to investigate the prevalence and disease distribution of hypertension among Nanchang residents;Then discuss related risk factors of hypertension in Nanchang to identify high-risk groups;Consequently,raise community hypertension prevention and control strategies and measures appropriate to the characteristics of Nanchang,provide scientific basis for the hypertension prevention and control mode in line with the actual situation of Nanchang.Methods: Use stratified cluster sampling method,a random sample of 10,562 cases of Nanchang community residents over the age of 18 were selected,chosen from 12 subdistrict offices or towns in 4 district of Nanchang.Questionnaire and physical measurements were used to investigate the prevalence of hypertension and related risk factors.Hypertension prevalent status and related factors of residents in Nanchang were analyzed by chi-square test and logistic regression.Results: Among 10,562 residents over 18 years old surveyed,2276 cases had hypertension,the hypertension prevalence rate was 21.55%,the standardized prevalence rate was 14.97%;the hypertension prevalence rate of male and female was 23.43%,19.79%,respectively.Among 8286 patients without hypertension,5545 cases have high-normal blood pressure,the high-normal blood pressure rate was 52.50%,standardized rate was 54.78%,the male high-normal blood pressure rate was 27.80%,the female high-normal blood pressure rate was 24.70%.Epidemiological characteristics of hypertension are: the prevalence rate of male is higher than female's(?2=20.730,P<0.05);the prevalence rate of hypertension increased with aging(?2=1574.829,P<0.05);Qingyunpu district's hypertension prevalence rate is the highest of 4 urban districts(?2=41.629,P<0.05);in the residents of different marital status,widowed residents has the highest hypertension prevalence rate(?2=297.189,P<0.05);unemployed residents have the highest prevalence rate of different occupations' residents(?2=240.049,P<0.05);higher education residents have the lower prevalence rate than the residents with lower education(?2=243.159,P <0.05);among different types of medical insurance's residents,those who have medical insurance for urban employees have the highest prevalence rate(?2=222.605,P<0.05);residents with family history of hypertension(?2=237.728,P<0.05)and coronary heart disease(?2=55.525,P<0.05)have significantly higher prevalence rate than the residents with no related disease family history.According to ?2 test result,we also have found that regular meals,tastes,frequency of tooth brushing,daily sleep time,the intake of milk and dairy products,whether concerned about nutrition labels,character,stress,BMI index are associated with the prevalence rate of hypertension(all P<0.05);multivariate Logistic regression analysis showed that: male(OR= 1.316,95%CI:1.183~1.464),older(OR=1.925,95%CI:1.846~2.008),medical insurance for urban employees(OR=1.198,95%CI:1.031~1.392),stress(OR=1.681,95%CI:1.470~1.923),overweight(OR=1.729,95%CI:1.543~1.938)or obese(OR=3.024,95%CI: 2.471~3.701),family history of hypertension(OR = 2.518,95% CI: 2.235~2.836)and coronary heart disease(OR=1.402,95%CI:1.085 ~1.812)are related risk factors of residents in Nanchang.High levels of education(OR=0.926,95% CI:0.878~0.976)is a protective factor of hypertension in Nanchang.Conclusion: Prevalence of hypertension in Nanchang is lower than the national average rate,but the rate of high-normal blood pressure is higher than the national level;hypertension distribution is inconsistent in different urban district;The hypertensive population distribution,compared with other regions,have both similarities and differences.Key risk factors can be changed are stress and overweight or obese.Nanchang hypertension prevention and control should be community-based,with general medical practitioners as the backbone,take eliminate or reduce the psychological stress of residents and interventions for weight control as the center,take the residents with “different districts and cultures,family history of hypertension and coronary heart disease” and people with high-normal blood pressure as the key population,insist the principle that “prevention is worth a pound of cure”,look health education and behavioral intervention as the starting point,build community hypertension intervention programs with Nanchang feature.Combining traditional community interventions with advanced technology,explore the new mode called “Internet+community prevention and control of hypertension”,earnestly complete the job of hypertension prevention and control,effectively reducing the level of prevalence of hypertension and protecting health of residents.
