RACE AND GENDER COMPARISONS .2. PREDICTIONS OF WORK BLOOD-PRESSURE FROM LABORATORY BASE-LINE AND CARDIOVASCULAR REACTIVITY MEASURES

In 148 Black and White men and women, laboratory measures of blood pre ssure (BP), heart rate, stroke volume (SV), cardiac output (CO) and to tal peripheral resistance (TPR) during baseline and 5 stressors were e xamined in relationship to ambulatory systolic (SBP) and diastolic (DB P) blood pressures at work. Baseline BP strongly predicted mean work l evels in all groups. For White men and Black women, higher SV and CO r esponses to the active speech and averaged across all tasks predicted higher work SBP individually and also when added to a model based on b aseline SBP, age, and diary information. For White women, higher SBP i ncreases to the passive speech similarly predicted mean work SBP. For Black men, higher TPR response to the cold pressor test correlated wit h higher work SBP but did not improve a predictor model involving base line SBP and age. Reactivity measures did not consistently contribute to prediction of work DBP.
