PURPOSE: The African-American-white mortality gap for males in the United States 
is 6 years in favor of whites. Participation in professional sport may moderate 
this ethnic disparity. The historical cohort of professional basketball players, 
with nearly equal numbers of African-American and white players, can provide a 
natural experiment that may control for the classic confounders of income, 
education, socioeconomic status (SES), and physical factors related to 
mortality. The objectives of this study are to assess mortality and calculate 
survival for the overall study population and within ethnicity.
METHODS: Data were combined from several publicly available sources. The cohort 
was analyzed to compare longevity among all players, and for players stratified 
by ethnicity, with the general U.S. population.
RESULTS: The final dataset included 3366 individuals, of whom 56.0% were African 
American. Results suggest white players live 18 months longer than their 
African-American colleagues. African-American players gained 9 years on their 
respective referent and live longer than white men in the general public. After 
controlling for covariates, we found that African-American players have a 75% 
increased risk of death compared with white players, a statistically significant 
gap (p < .0001, 95% confidence interval 1.41-2.44).
CONCLUSIONS: The African-American-white mortality gap for males is largely 
ameliorated (1.5 years vs. 6.1 years) in professional basketball but still 
persists.
