STUDY ON PRE-HYPERTENSION PREVALENCE AND RELATIONSHIP WITH DYSLIPIDEMIA IN ADULTS AT QUANG NAM PROVINCE

Abstract

Objectives: To investigate the prevalence, risk factors of prehypertension in QuangNam province of Vietnam. Methods: A case-control study of 3,237 adults (aged ≥ 25 years) was conducted in Quang Nam province, Vietnam in 2017, using questionnaire interviews, clinical examinations, and laboratory tests. Blood pressure, anthropometry, plasma glucose and lipids were measured. The variables contributing significantly to pre-hypertension were analyzed by multiple logistic regression analysis. Results: The prevalence of prehypertension was 30.7%, hypertension 31.6% and normal blood pressure was 37.7%. Lipid disorders such as high total cholesterol levels, high triglyceride levels, high LDL-C levels were significantly higher in prehypertensive than optimal blood pressure (BP). Multivariable logistic regression analysis revealed strong positive associations of pre-hypertension with high triglyceride levels (OR = 1.41, CI 95%: 1.13 - 1.75, p = 0.002); high LDL-C levels (OR = 1.42; CI 95%: 1.03 - 1.97; p = 0,034). The area under the ROC curve of triglyceride, cholesterol, LDL-C was 0.578; 0.566; 0.549, respectively. There was a positive correlation of blood cholesterol, blood triglyceride, blood LDL-C with changes in systolic BP, diastolic BP, and average BP. Conclusions: The prevalence of prehypertension in Quang Nam province of Vietnam was 30.7%. High cholesterol, high triglycerides, high LDL-C level were significantly associated with prehypertension. Key words: Lipid – prehypertension
