Racial and ethnic differences in asthma and mental health among US adults: results from the national survey on drug use and health

Abstract

Objective: Evaluate the racial and ethnic differences in asthma and mental health comorbidity. Methods: A secondary analysis of 2008–2013 National Survey on Drug Use and Health was conducted, resulting in a total of 206 993 civilian adult respondents to evaluate the association between asthma and mental health (past year serious psychological distress [SPD] and doctor diagnosis of depression). Both survey weighted bivariate (chi-square) and multivariable (binary logistic) regression analyses, after accounting for control variables, were conducted to evaluate the asthma/mental health nexus. A p value of less than 0.05 was used to denote significance. Results: Current asthma was significantly associated with past year SPD for non-Hispanic Whites (adjusted odds ratio [aOR] = 1.45), Hispanics (aOR = 1.68), and Black/African Americans (aOR = 1.47). A similar association was noted for current asthma and past year doctor diagnosis of depression (non-Hispanic White aOR = 1.74; Hispanics aOR = 1.77; Black/African American aOR = 1.62). Among those with lifetime asthma, higher odds of SPD were reported for non-Hispanic Whites (aOR = 1.42), Hispanics (aOR = 1.64), and Black/African Americans (aOR = 1.50). Lifetime asthma also significantly associated with past year doctor diagnosis of depression for non-Hispanic Whites (aOR = 1.42), Hispanics (aOR = 1.41), and Black/African Americans (aOR = 1.46). Conclusion: Our results demonstrate the significant burden of asthma and mental health comorbidity among diverse racial and ethnic groups. Improved public health efforts through promotion of integrated care for early screening and preventive measures are needed to alleviate the burden for at-risk groups.
