aIncrement in BP for each 1-cm increment in height component.
Model 1: adjusted for age, sex, race and measurement conditions (state, arm, cuff size, body position, indicator for the sequence number (1st through 5th)), N = 1086.
Model 2: model 1 + maternal and paternal height and BMI, N = 1028.
Model 3: model 2 + sum of SS + TR skinfold thickenesses measured at the mid-childhood visit, N = 1023.
Model 4: model 3 + maternal education, marital status and household income at the mid-childhood visit, maternal smoking during pregnancy, parity, N = 976.
Model 5: model 3 +the other component of current height (leg length for trunk length and vice versa), N = 1023.
