BODY-MASS INDEX AND BODY GIRTHS AS PREDICTORS OF MORTALITY IN BLACK-AND-WHITE MEN

Anthropometric measurements collected from black and white men in the 1960 (n = 946) and 1963 (n = 456) examinations of the Charleston Heart Study cohort (Charleston County, South Carolina) were examined as predictors of all cause and coronary heart disease mortality. Anthropometric measurements included body mass index, chest girth (at the third intercostal space), abdominal girth (at the umbilicus) and midarm circumference. Vital status of 98 percent of the cohort was determined through 1988. Body mass index was not associated with mortality in the white men; however, it was predictive of all cause and coronary heart disease mortality in the black men. Analyses conducted separately in the lower and upper range of body mass index in black men showed the adjusted relative hazard at the 50th versus the 10th percentile of body mass index was 0.54 for all cause mortality, but was not significant for coronary heart disease mortality; whereas the adjusted relative hazard for the 90th relative to the 50th percentile was 1.7 for coronary heart disease deaths, but not significant for deaths from all causes. The circumference measurements were not predictive of all cause or coronary heart disease mortality in the white men. In the black men, the adjusted relative hazard ratios for all cause mortality for the 85th relative to the 15th percentiles were 0.22 for midarm circumference and 2.0 for abdominal circumference.
