| Annotation | The authors used a cross-sectional design to examine age and gender differences in blood pressure and impedance-derived measures of cardiovascular reactivity during acute psychosocial stress in 133 participants aged 30-70. Results revealed that age predicted increased systolic blood pressure (SBP) reactivity during stress. The greater SBP reactivity found in older people appeared due to an age-associated increase in both cardiac output and total peripheral resistance during stress as statistically controlling for these changes rendered the age and SPB reactivity effect non-significant. Similar analyses revealed that the age-related increase in cardiac output reactivity appeared to be driven by increased cardiac sympathetic control of myocardial contractility as measured by pre-ejection period. Older people also had greater vagal withdrawal during stress compared to younger individuals as indexed by respiratory sinus arrhythmia. These results were comparable for men and women, and could not be explained by task-specific, affective responses, task performance, or demographic factors. (RH). |
