Abstract
OBJECTIVE: To examine the relationship between body mass index (BMI), gender, age, controller medication use, household smoke exposure, season, and allergic rhinitis status with asthma control in a group of lower income, African American children. We hypothesized that non-obese children would have better asthma control. METHODS: Baseline data from a longitudinal study of children in a school-based asthma program in a Midwest urban area were analyzed. 360 children, ages 4-15 years, who were enrolled in either the 2012-2013 or 2013-2014 program were included. Asthma control was classified using criteria from the 2007 National Asthma Education and Prevention Program. Multiple ordinal regression was performed. RESULTS: The median age was 9 years, 61% had well-controlled asthma, and 29% were obese. The model included all main effects plus two interaction terms and was significant (χ2(7) = 22.17, p =.002). Females who were normal weight (OR, 2.78; 95% CI, 1.38-5.60, p =.004) or overweight (OR, 3.12; 95% CI, 1.26-7.72, p =.014) had better asthma control than obese females. For males, there were no differences by BMI category but males without allergic rhinitis had significantly better asthma control (OR, 2.23; 95% CI, 1.25-3.97, p =.006) than those with allergic rhinitis. CONCLUSIONS: Non-obese girls and non-allergic males had better asthma control. Promotion of healthy activity and nutrition as well as management of allergic rhinitis should be part of the asthma plan in school-based programs in low income urban areas. Innovative approaches to address asthma care in low income populations are essential.
