Prehypertension was defined if individuals were not undergoing antihypertensive treatment and had a systolic blood pressure (SBP) of 120–139 mm Hg and/or diastolic blood pressure (DBP) of 80–89 mm Hg. Individuals with optimal blood pressure (SBP <120 mm Hg and DBP <80 mm Hg) were used as the reference group.
