SBP: Systolic blood pressure; DBP: Diastolic blood pressure; GLU: Glucose; TC: Total cholesterol; TG: Triglycerides; HDL-C: High-density lipoprotein cholesterol; LDL-C: Low-density lipoprotein cholesterol; UA: Uric acid. p: All participants from the normotension, pre-hypertension and hypertension groups had the variables analyzed by one-way ANOVA or Chi- square test.#: p<0.05 vs. Normotension.*: p<0.05 vs. Pre-hypertension.
