Abstract: ObjectiveTo investigate correlation between hyper lipemia and hypertension in Mongolian people.MethodThe blood pressure and so on were measured and factors including smoking cigarette and alcohol intake,and blood lipids for 2 547 Mongolian people aged 20 and elder were investigated,the statistic analysis were done by using chisquare test and multiple logistic model,and correlations were evaluated by using oddratio(OR),dose-effect relations between TG and hypertesion were analyzed by means of Mantel-Haenszel chi square trend test.ResultsSingle factor analysis showed that high total cholesterol(TG),high triglyceride(TG),high low density lipoprotein-cholesterol(LDL-c)were all correlated with hy pertension.After adjustment for age,gender,body mass index(BMI),wais-thip ratio(WHR),blood glucose and family history of hyper tension by multiple logistic model,there were no correlations between high TC,high LDL-c and hypertension(P>0.05).There were still a significant correlation between high TG and hyper tension((OR 1.579,95% CI 1.232~2.024).Resultsof dose-effect analysis showed that the risk of prevalence for hypertension increased with TG level.ConclusionHigh TG may be a independent risk factor of hypertension in Mongolian people,and there was a tendency that the risk of prevalence of hyper tension increased with TG level.
