All data are presented as number (%) unless otherwise indicated.
Other races: white (12%), American Indian or Alaska native (1%), and native Hawaiian or other Pacific Islander (1%).
Ever-smoker was defined as more than 100 lifetime cigarettes versus never-smoker.
Insufficient vision was defined as worse than 20/50 vision in both eyes using the Snellen chart.
Health literacy was assessed in 102 participants with brief intervention (n = 50) or treat-to-goal intervention (n = 52). The remaining subjects had insufficient vision to complete assessments (n = 18). Less than adequate health literacy was defined as a score less than 23 of 36 on the Short Test of Functional Health Literacy (24).
Identified either a general physician, specialist physician (pulmonologist or allergist), or nurse practitioner as providing care for participants’ asthma or COPD.
