Race affects the decline in blood pressure with hospitalization.

Hospitalization routinely lowers blood pressure (BP). This study examined the effects of race and psychologic characteristics on this phenomenon. Data are reported from two separate cohorts of hypertensive and normotensive black and white men and women who were studied following a stay at a clinical research center where sodium intake was held constant. Blacks (N = 88), as compared to whites (N = 77), showed consistently smaller declines in systolic BP (P < .01) following hospitalization (-11.6 mm Hg SBP v -19.5 mm Hg SBP, respectively). A multiple regression model that treated BP as a function of physiologic and psychologic attributes indicated that preadmission BP level, body mass index, stress level, and anger expression were related to the drop in systolic (r2 = 65%) and diastolic (r2 = 45%) BP brought about by hospitalization (P < .0001). In blacks, high environmental stress ratings were unrelated to the change in BP with hospitalization. In contrast, whites with high environmental stress ratings lowered their BP noticeably with hospitalization. Given that the reduction in BP with hospitalization can be similar to that attained with pharmacologic therapy, these findings may have a bearing on studies examining BP in the hospital.[1]
