Asthma in Miami-Dade County, Florida and United States High School Students: Contrasting Trends in Racial/Ethnic Disparities
Methods: We compared trends in asthma prevalence in Miami-Dade and US high school students by year and race/ethnicity from 2005-2013 using the CDC Youth Risk Behavior Surveillance System. An asthma diagnosis was an affirmative answer to the question “Have you ever been told by a doctor or nurse that you have asthma?”
Results: Asthma prevalence in Miami-Dade students did not differ significantly by race or ethnicity in 2005 (17.2%, African-Americans; 16.5%, Hispanics; 16.2% Whites; p>.60), but rose from 2005 to 2013 to 28.0% in African-Americans and to 21.0% in Hispanics (both p<.01). Prevalence decreased in White Miami-Dade students to 12.6%, differing significantly in 2013 from prevalence in African-Americans and Hispanics. In contrast, asthma prevalence also rose nationally from 17.1% to 21.0%; p<.01), but nationally, asthma prevalence converged in 2013 at 19.9%-20.3% for White, Hispanic, American Indian/Alaska Native (AI/AN) and Asian students due to increased prevalence in Whites, Asians and Hispanics, and decreased prevalence in AI/ANs. Only African-Americans had higher asthma prevalence in 2013 nationwide (26.0% versus 20.3% in Hispanics and AI/ANs, and 19.9% in Whites [p<.01]).
Conclusion: Striking racial and ethnic disparities emerged in asthma in Miami-Dade students due to increases in prevalence in African-Americans and Hispanics during an economic downturn that began in 2007 in Miami-Dade. Conversely, the national downturn affected students more uniformly, increasing disparities only between African-Americans and others.
