The disparity in health status between black and white Americans exists chiefly because of an excess of preventable disease in blacks. This situation calls for an increase in preventive services for blacks, services which might best be implemented or directed by black specialists in preventive medicine. ⋯ The immediate need for additional black specialists exceeds the total U. S. preventive medicine residency corps.

A 44-item knowledge and attitude questionnaire was administered to 176 randomly selected shoppers to determine their cardiovascular and nutrition knowledge and attitude toward the diet-heart relationship. An analysis of descriptive sales slips issued by the supermarket determined food purchasing behavior. Food items purchased were categorized according to their polyunsaturated-saturated (P/S) ratio less than 1 (PS0), P/S ratio greater than 1 (PS1), and high cholesterol (greater than 100 mg per serving) (HCHO). ⋯ Correlation for whites was significant and negative (r = -.29, P = .0003) and for blacks nonsignificant and positive (r = .02, P = .9069). Regression analysis found a significant negative slope (b = -.57, P = .0001) of PS0 on knowledge, a marginally significant positive slope (b = -.21, P = .0527) of PS1 on knowledge, and a significant negative slope (b = -.86, P = .0171) of HCHO on education. The interaction of race and knowledge was significant for PS0 (P = .0005).
