Race and sex differences in cardiovascular recovery from acute stress

To evaluate the effects of race and gender on recovery, i.e. the relative return to baseline after a stress challenge, cardiovascular and catecholamine measures were examined before, during, and after two standardized laboratory Stressors (a speaking and a mirror tracing task) in a group of 85 Black and White men and women (mean age 35.6 years, range 20 to 52). For the speech task, White men showed the least systolic ( p < 0.025) and diastolic ( p < 0.05) blood pressure recovery as compared to Black men and women. For the mirror star tracing task, total peripheral resistance ( p < 0.03) recovery was least for Whites as compared to Blacks and heart rate ( p < 0.04) recovery was least for White women as compared to Black women and men. There were no significant group effects in terms of catecholamine recovery from either task. The findings extend prior studies on race and gender by suggesting that these same characteristics affect recovery from Stressors.
