| Objective:To compare the distribution of hypertension and its influencing factors,and the relationship between hypertension and its influencing factors in Korean and Han nationality of Yanbian Korean Autonomous Prefecture area.Methods:①Using a simple random sampling method,3,158 permanent residents aged more than 30 years and selected in the Antu County of Yanbian were carried out an investigation from August 2005 to August 2006.All of subjects was selected after eliminating the cases suffered from serious organic diseases and knew the informed consent.②Using the home visit and health examination,the relevant information for this study were collected in the selected communities and health centers.③The investigators were trained, and it was standardized that the survey contents,operational procedures and methods,and the home visit and inquiries were performed in accordance with unified questionnaire (including the general information,smoking,drinking,past history and family history of cardiovascular diseases,etc.).④It was measured that the height,weight,waist circumference and blood pressure,etc.⑤The fasting vein blood(fasting for 12 h) was taken in early morning,and it was measured that the serum total cholesterol(TC),triglyceride (TG),high-density lipoprotein cholesterol(HDL-C),blood glucose.The blood lipids and blood glucose were measured by automatic biochemical analyzer.⑥The measurement data were examined by ANOVA test;the numeration data were compared with the Chi square and u test;the hypertension and its subtypes influencing factors were analyzed by the multi-regression analysis;hypertension and its subtypes as the dependent variable and nationality,age,sex,hyperglycemia,high total cholesterol,high triglyceride,high TC and TG,overall obesity and abdominal obesity as independent variable were analyzed by the Logistic regression analysis;the variables were selected by BACKWARD,selected variables were significant level asα=0.05 and deleted variables were significant level asα=0.10. Results:Out of 3,158 cases,1,358 cases(43.0%) were Korean nationality(566 of male and 792 of female),and 1,800 cases(57.0%) were Han nationality(654 of male and 1,146 of female).①For female,the average level(mmHg) of systolic blood pressure(SBP) 130.3 in Korean nationality,and that was 124.7 in Han nationality,and there was significant ethnic difference(P＜0.05);the average level(mmHg) of diastolic blood pressure(DBP) was 88.2 in Korean men and 86.0 in Han men,and 85.1 in Korean women and 81.7 in Han women, respectively,and there were significant ethnic differences(P＜0.05).②In this study population,the crude rate of hypertension was 52.3%in Korean men,41.0%in Han men, 40.9%in Korean women and 29.7%in Han women,respectively;the age-adjusted prevalence of hypertension was 44.9%in Korean men,39.4%in Han men,31.6%in Korean women and 28.6%in Han women,respectively.The crude and the age-adjusted prevalence of hypertension in Korean nationality were significantly higher than those in Han nationality in both sexes(P＜0.01).The prevalence of hypertension increased along with the increase of age(P＜0.01).③The age-adjusted prevalence of isolated systolic hypertension(ISH), isolated diastolic hypertension(IDH) and systolic combined diastolic hypertension(SDH) was 4.3%,16.8%and 23.8%in Korean men and that was 4.1%,16.8%and 18.5%in Han men,respectively,and there were significant ethnic differences in ISH(P＜0.05) and SDH (P＜0.01).For female,the age-adjusted prevalence of ISH,IDH and SDH was 4.3%,16.8% and 23.8%in Korean and that was 6.0%,8.0%and 14.6%in Han,respectively,and there were significant ethnic differences(P＜0.01) in all subtypes of hypertension.The prevalence of ISH and SDH was progressively higher and the IDH progressively lower with the increases of age.④The proportion of ISH,IDH and SDH were12.1%,31.0%and 56.9% among Korean hypertensive population,and that were 14.3%,33.7%and 52.0%among Han hypertensive population,and SDH was more frequent in this area.The ages in proportion of IDH,ISH and SDH were significant differences.Among Korean hypertensive population of age＜30 years,the proportion of IDH,ISH and SDH were 53.3%,6.7%and 40.0%, respectively,and that of Han were 57.8%,8.4%and 33.7%,respectively,and among Korean hypertensive population of 40～50 years,that were 36.5%,8.2%and 55.3%,respectively,and that of Han were 34.8%,10.9%and 54.3%.In contrast,among Korean patients of age≥60 years,the proportion of IDH,ISH and SDH were 16.9%,20.4%and 62.7,respectively,and that of Han were 13.3%,30.0%and 56.7%,respectively.Among hypertensive population, the proportion of ISH and SDH were progressively higher and that of IDH progressively lower with the increases of age.⑤In comparison with normal blood pressure(NBP) subgroup,age,TG,SBP and DBP was significantly increased in ISH among Korean population(P＜0.01),and age,WHtR(P＜0.05),SBP and DBP were significantly increased in ISH among Han population(P＜0.01);BMI,WHtR,TC,TG,SBP and DBP were significantly increased in IDH among combined population of Korean and Han(P＜0.05); age,BMI,WHtR,TC(P＜0.05),TG,SBP and DBP were significantly increased in SDH among combined population of Korean and Han(P＜0.01).⑥The results of multifactor analysis showed that hypertension is closely related with nationality(Korean),sex,age, overall obesity,abdominal obesity,high TC,high TG,high TC combined high TG and smoking;ISH is closely related with nationality(Korean),age,abdominal obesity and hyperglycemia;IDH is closely related with nationality(Korean),sex,age and abdominal obesity;SDH is closely related with nationality(Korean),sex,age,overall obesity, abdominal obesity,high TC,high TG,high TC combined high TG and smoking.Conclusion:①The prevalence of hypertension and its subtypes in the general population is relatively high in Yanbian area and the distribution of that between Korean nationality and Han nationality were significant difference,and the prevalence of hypertension increased along with the increase of age(P＜0.01);②The proportion of ISH,IDH and SDH among hypertensive population had significant ethnic differences.ISH and SDH were progressively higher and the IDH progressively lower with the increases of age,and the SDH was more frequent in this area;③In comparison with normal blood pressure(NBP) subgroup,age,TG, SBP and DBP was significantly increased in ISH among Korean population,and age,WHtR, SBP and DBP were significantly increased in ISH among Han population;BMI,WHtR,TC, TG,SBP and DBP were significantly increased in IDH among combined population of Korean and Han;age,BMI,WHtR,TC,TG,SBP and DBP were significantly increased in SDH among combined population of Korean and Han(P＜0.01).④Hypertension is closely related with nationality(Korean),sex,age,overall obesity,abdominal obesity,high TC,high TG,high TC combined high TG and smoking,and the distribution of these influencing factors in subtypes of hypertension were significant difference. |
