In the United States, asthma prevalence, especially morbidity and mortality, is higher in blacks than in whites. Although genetic factors are of major importance in determining a predisposition to the development of asthma, environmental factors play a greater role than racial factors in asthma onset. A national concern is that some of the increased morbidity is due to differences in asthma treatment afforded certain minority groups. Larger asthma-associated lung function deficits are reported in Hispanics, especially females. [32]
