Income is an independent risk factor for worse asthma outcomes.

ABSTRACT: BACKGROUND:Socioeconomic status (SES) is associated with asthma morbidity in observational studies, but the factors underlying this association are uncertain. OBJECTIVE:We investigated whether 3 SES correlates-low income, low education, and high perceived stress-were independent risk factors for treatment failure and asthma exacerbations in the context of a randomized controlled trial. METHODS:The effect of low SES (household income of <$50,000/y and household educational level of less than a Bachelor's degree) and high perceived stress (defined as a score of >20 on a perceived stress scale) on asthma morbidity was analyzed in 381 participants by using Poisson regression models. The primary outcome was treatment failure (defined in the trial protocol as a significant clinical or airflow de
