Four Logistic regression models predicting hypertension, SBP and DBP using WC D-value, BMI D-value or combined D-values a
| Variables | WC D-value | BMI D-value | WC D-value and BMI D-value | |
|---|---|---|---|---|
| alone | alone | WC D-value | BMI D-value | |
| Males (n=1097) | ||||
| Hypertension | 1.04 (1.02-1.07)b | 1.09 (1.04-1.18)b | 1.03 (1.01-1.06)b | 1.04 (0.97-1.12) |
| SBP | 1.03 (1.01-1.06)b | 1.08 (1.02-1.15)b | 1.02 (1.01-1.05)b | 1.04 (0.96-1.12) |
| DBP | 1.09 (1.06-1.12)b | 1.20 (1.11-1.30)b | 1.06 (1.02-1.09)b | 1.06 (0.98-1.14) |
| Females (n=1681) | ||||
| Hypertension | 1.03 (1.02-1.05)b | 1.03 (0.98-1.09) | 1.03 (1.01-1.05)b | 1.01 (0.97-1.06) |
| SBP | 1.04 (1.02-1.05)b | 1.08 (1.03-1.13)b | 1.03 (1.01-1.05)b | 1.03 (0.98-1.09) |
| DBP | 1.04 (1.01-1.06)b | 1.03 (0.99-1.10) | 1.03 (1.01-1.06)b | 1.02 (0.97-1.08) |
CI, confidence interval; OR, odds ratio; D-value, difference value. / a BMI D-value and WC D-value were included in the multilevel regression model as continuous variables, and the ORs were computed for each unit increase in BMI (kg/m2) and WC (cm). The ORs were adjusted for age, TC, HDL-C, LDL-C, FPG, TG, smoke and alcohol status, family history of hypertension. A low level of multicollinearity between WC D-value and BMI D-value, and among triglycerides, HDL-C, total cholesterol and LDL-C was found, because tolerance values were >0.5, VIF<10. / b Significantly greater odds, P<0.05
