Abstract

The epidemiology of a common measure of cardiovascular reactivity, the change in systolic blood pressure (Delta SBP) from the supine to the standing position, is described in a cohort of 13 340 men and women aged 45 to 65 years enrolled in the Atherosclerosis Risk in Communities (ARIC) Study. The distribution of Delta SBP was found to be symmetrical and unimodal, with a mean value near zero (-0.45 mm Hg), The range of Delta SBP was from -63.2 to54.3 mm Hg, and the standard deviation was 10.8. Stratification of Delta SBP by race and gender shows a slight shift in distribution toward higher values for black men and women. Delta SBP was categorized into deciles. Participants in the top 30% and bottom 30% of the distribution were compared with individuals in the middle 40% of the distribution, who had little or no change in SEP on standing. Participants in the bottom 30% (ie, SEP decreasedon standing) were significantly older, had a greater prevalence of hypertension and peripheral vascular disease, had higher values of SEP, and had more cigarette-years of smoking. Among participants in the top 30% (ie, SEP increased on standing), a significantly larger proportion were black, mean seated SEP was higher, and the predicted risk of developing coronary heart disease after 8 years was greater. The response of SEP to change in posture showed considerable variability in a population sample of middle-aged adults. Cardiovascular morbidity, sociodemographic factors, and cigarette smoking were associated with the magnitude and direction of the postural change.
