Study of correlations between metabolic risk factors, PWV and hypertension in college students

摘要

Objective: Obesity, dyslipidemia and diabetes have been recognized as risk factors of hypertension in the general population. This study focused on college students and correlations between serum lipids, serum uric acid, fasting plasma glucose, serum creatinine, body mass index, brachial-ankle pulse wave velocity and hypertension. The results suggested that there was no relevance between serum lipids and hypertension. However, it came out that hypertension is associated with normal fasting plasma glucose, BMI (thinness and normal weight), normal serum creatinine. Methods: A total of 5185 students were enrolled, and their blood pressure, height and weight were measured. 285 of the students were selected to take physical examinations including serum uric acid, total cholesterol, low-density lipoprotein cholesterol, triglyceride, high-density lipoprotein cholesterol, fasting plasma glucose, serum creatinine, blood urea nitrogen, ankle-brachial index and brachial-ankle pulse wave velocity measured. Results: The values of systolic blood pressure(SBP), diastolic blood pressure(DBP), serum uric acid, fasting plasma glucose(FPG), serum creatinine, body mass index(BMI), and brachial-ankle pulse wave velocity(baPWV) were higher in hypertension group than those in non-hypertension group (P < .001, <0.001, <0.001, = 0.009, = 0.07, <0.001, <0.001, respectively). Logistic regression showed correlations between hypertension and hyperuricemia (OR = 2.975, 95%CI: 1.672-5.291), obesity (OR = 2.814, 95%CI: 1.297-6.105), fasting plasma glucose (OR = 2.184, 95%CI: 1.090-4.378) and brachial-ankle pulse wave velocity (OR = 1.005, 95%CI: 1.003-1.007). The AUC was 0.786 (95%CI: 0.729-0.842, P < .0001). We can draw a conclusion that hyperuricemia, obesity, fasting plasma glucose and brachial-ankle pulse wave velocity, listed in descending order of influence, are risk factors for hypertension in college students.
