RATIONALE: Asthma disproportionately impacts the Hispanic/Latino population. Poor sleep quality frequently coexists with asthma. We used the Hispanic Community Health Study of Latinos (SOL), a large-scale multicenter study, to examine the relationship between asthma and insomnia in Hispanics/Latinos.

METHODS: We performed an exploratory survey analysis of the relationship between self-reported asthma and insomnia, measured by the Epworth Sleepiness Scale (ESS, >=10 for insomnia) and the Women’s Health Initiative Insomnia Rating Scale (WHIIRS, >=9 for insomnia). Multiple survey logistic regression with backward model selection adjusted for demographic, behavioral, and other clinical factors found significant in exploratory and bivariate analyses was performed.

RESULTS: In bivariate analyses, asthma was associated with insomnia by ESS (Odds Ratio (OR): 1.34, 95% Confidence Interval (CI): 1.07-1.68) and by WHIIRS (OR: 1.41, 95% CI: 1.16-1.71). Age, higher body mass index (BMI), tobacco use, greater physical activity, higher income, antidepressant use, and Central American, Mexican, Puerto Rican, and South American heritage (Reference: Multiple/Other/Unknown heritage) were independently associated with insomnia by either ESS or WHIIRS. In multivariate models, asthma remained associated with insomnia by ESS (Adjusted OR (AOR): 1.31, 95% CI: 1.03-1.67) after adjusting for BMI, tobacco use, physical activity, antidepressant use, and Hispanic heritage and by WHIIRS (AOR: 1.27, 95% CI: 1.03-1.56) after adjusting for age, tobacco use, income, antidepressant use, and Hispanic heritage.

CONCLUSIONS: Insomnia is associated with asthma in a large Hispanic/Latino asthmatic population with multivariate modeling. Future studies should consider the contribution of insomnia to asthma morbidity in the Hispanic/Latino population.
