    Abstract:
    OBJECTIVE: Common comorbid medical conditions including allergic rhinitis (AR), obesity, and sleep disordered breathing (SDB) have been linked with asthma exacerbations; however, these conditions also impact sleep and academic functioning. The current study sought to examine unique and combined associations of these common comorbidities on sleep and academic performance among urban minority children with persistent asthma. We expected additional comorbid diagnoses would be associated with poorer sleep and academic functioning. METHOD: Urban children 7-9 years old (n = 249) with persistent asthma from African American, Latino, and non-Latino White backgrounds participated in this cross-sectional study. Asthma and AR were assessed using guidelines-based approaches. Overweight/obesity was assessed using body mass index and parents reported on SDB risk. Sleep quality (sleep efficiency) and sleep duration were assessed via 4 weeks of actigraphy. A cumulative risk index (CRI) score of asthma-related comorbidities (i.e., number of comorbidities for which each child met criteria) was calculated. RESULTS: Comorbid conditions were prevalent (AR, 85%; overweight/obese, 39%; SDB risk, 44%). Lower SDB risk and better AR control were both associated with fewer school absences. A higher CRI score was associated with shorter sleep duration and more absences. For children with 1 comorbid condition, better lung function was associated with better sleep efficiency. CONCLUSION: Findings suggest increased risk of shorter sleep and more frequent school absences among urban minority children with asthma and more comorbid conditions. Assessment and treatment of this high-risk group must consider how comorbid conditions exacerbate children's asthma and may affect sleep and daytime functioning.
