RATIONALE: In this study we analyzed family history, ethnicity, body mass index, allergic rhinitis, and eczema and assessed their risk for persistent asthma.METHODS: The study population included 381 children who were 5-18 years old that were treated on the Breathmobile, a fully equipped mobile asthma clinic. Patients who were taking controller medications were excluded due to possible confounding factors.RESULTS: A greater percentage of African-American children had moderate to severe persistent asthma (16.7%) compared to Hispanic children and other ethnicities, 5.8% and 8.1% respectively (p = .019). Children with obesity (BMI > 30) were more likely to have moderate to severe asthma (37.9%) compared to normal (21.6%, BMI < 25) and overweight children (21.5%, BMI25-30), p = .043. In terms of family history, a significantly greater proportion of children had persisent disease who had 2 parents with asthma compared to the mean of all other categories combined (58.3% vs. 31%, p = .048). Other categories that had persistent asthma included 1 parent (37%), distant relatives only (33%), siblings only (11.1%), siblings and distant relatives only (25%), and no family history of asthma (22%). Children with chronic nasal symptoms were more likely to have persistent asthma compared to children with intermittent or no nasal symptoms (47.3%, 22.9%, and 9.8% respectively, p < .001). Children with eczema had more persistent asthma compared to children with no eczema (p = .009).CONCLUSIONS: Persistent asthma was observed significantly more often in children with 2 asthmatic parents, and children with chronic rhinitis and eczema. Moderate to severe persistent asthma was observed significantly more often in African-American children, and obese children with BMI > 30.
