Note. SBP = systolic blood pressure. DBP = diastolic blood pressure. PR = pulse rate. For cardiovascular medications, 0 = does not take blood pressure/heart medications, 1 = takes blood pressure/heart medications. In Model 1, SBP reactivity is being tested such that the dependent variable is average task SBP. In Model 2, DBP is being tested such that the dependent variable is average task DBP. In Model 3, PR reactivity is being tested such that the dependent variable is average task PR. Unstandardized coefficients are reported for the intercepts in both models. All other beta coefficients represent standardized values. Adjusted R Square refers to the covariate only model (Step 1) and the R Square Change refers to the additional amount of variance explained by including age group in the model (Step 2).
