Expression of Sympathetic Activity in College Students with Hypertension |Biomedgrid

To explore the expression of sympathetic activity in college students with hypertension. Methods: A random and cluster sampling was used to recruit subjects; 5185 students were collected in this investigation from 3 universities in Zhengzhou from March to December 2018. Stratified sampling in R language was used to select 184 from non-hypertension students, 201 from hypertension students. Serum dopamine (DA), norepinephrine (NE), epinephrine (E), plasma renin activity (PRA), angiotensin II (AngII), aldosterone (ALD), urine sodium and resting heart rate (HR) were tested for 385(184+201) students, using independent samples test to compare the difference between two groups, Spearman rank correlation coefficient to assess the correlation of physicochemical parameters and hypertension, and multiple linear regression to analyze the risk factors of hypertension. 385 students were divided into two groups---overweight group and non-overweight group---according to the BMI.
