Persky, V. (School of Public Health, U. of Illinois, Chicago, IL 60680), W. H. Pan, J. Stamler, A. Dyer, and P. Levy. Time trends In the US racial difference in hypertension. Am J Epidemiol 1986;124:724-37.This paper explores time trends in racial differences In hypertension and in mortality from complications from hypertension in the United States. Mortality data were derived from death certificate data complied by the National Center for Health Statistics and presented in the 1981 Report of the WorkIng Group on Arteriosclerosis. Prevalence data were obtained from five populations-6,672 people screened in 1960-1962 by the National Health Examination Survey (NHES); 20,749 screened in 1971-1975 by the Health and Nutrition Examination Survey (HANES I); 158,539 screened in 1973-1974 by the Hypertension Detection and Followup Program (HDFP); 1 million persons screened in 1973-1975 by the Community Hypertension Evaluation Clinics (CHEC)l and 20,325 screened in 1976-1980 by the second Health and Nutrition Examination Survey (HANES II) Mortality data Indicate that the nonwhite/white ratios for mortality from complications of hypertension increased between 1940 and 1967 and decreased between 1968 and 1978. Prevalence data show a corresponding recent decrease in black minus white mean blood pressure. Some of the decrease appears to be due to a greater improvement in hypertension control for blacks than for whites. Time trends in the black/white ratio In prevalence of hypertension were examined with differential treatment effects controlled by Inclusion as hypertensive those on drug therapy. The results Indicate that in addition to differential changes in therapy, the ratio of black/white prevalence of hypertension may also be decreasing. Additional studies are needed to confirm this finding and to explore time changes in racial patterns of risk factors for hypertension.
