  1. SBP = systolic blood pressure, DBP = diastolic blood pressure, HDL- and LDL-cholesterol, TRG = triglycerides, GLU = fasting glucose, ≤ 43 yrs = young and > 43 yrs = old. **Except for HDL-cholesterol, differences in the mean values within sex between age groups were statistically significant at 5% according to the t-test.
