Note. AOR = adjusted odds ratio; BMI = body mass index (defined as weight in kilograms divided by the square of height in meters); BRFSS = Behavioral Risk Factor Surveillance System; CI = confidence interval; eHealth-PHINEX = Electronic Health Record Public Health Information Exchange.
US and Wisconsin BRFSS adult asthma models adjusted for gender, age group, race/ethnicity, smoking status, BMI, and household income. Passive smoking status and insurance status were not available for adults in the BRFSS.
University of Wisconsin eHealth-PHINEX model adjusted for all variables in table including gender, age group, race/ethnicity, smoking status, BMI, median household income for a patient’s census block group, and insurance status.
