Abstract
INTRODUCTION: Data to assess factors associated with differences in coronary heart disease mortality between Caucasians and African Americans are limited. We assessed risks for sudden, nonsudden, and other coronary death between Caucasians and African Americans in relation to known risk factors for coronary disease and socioeconomic status. METHODS: We analyzed data from the 1986 National Mortality Followback Survey, the 1985 National Health Interview Survey, and the U.S. Bureau of the Census. Logistic regression methods were used to create multivariate models to assess the relationship of socioeconomic status and other known modifiable risk factors to death from each of the three coronary diseases for Caucasians and African Americans separately. RESULTS: In an age- and gender-adjusted analysis of data on men 25-44 years old and women 25-54 years old, African Americans had about twice the risk for sudden, nonsudden, or other coronary death as did Caucasians. Adjusted risks for coronary death for Caucasians associated with modifiable risk factors (cigarette smoking, body weight, diabetes, and hypertension) either resembled or were slightly greater than those for African Americans. Half or more of all excess risks for African Americans in multivariate models could be explained by socioeconomic status. About 18% of excess sudden coronary death risk could be further explained by known modifiable coronary heart disease risk factors. CONCLUSIONS: Broad public health efforts are needed to address these causes of excess mortality.
