The mechanisms underlying this association are not fully elucidated. However, because obstructive sleep apnea is treatable, screening for sleep disorders should be considered in patients with severe asthma and uncontrolled disease. The efficacy and implications of treatment with continuous positive airway pressure to improve asthma control remain unclear, although there are some promising results showing improved asthma outcomes. Further research is needed to enlighten the relationship between asthma and obstructive sleep apnea, and to better define the role of continuous positive airway pressure therapy in improving asthma control and outcomes in comorbid patients with asthma and obstructive sleep apnea.

We addressed this question with two approaches. First, we identified 36 US-based studies that had student participants and a psychoeducational sleep intervention. Fifteen authors shared data on sleep knowledge, quality, and/or duration separated by gender and URM groups (N = 599). Hedges' g was computed for each group within each study. Second, we systematically reviewed the content of 21 available programs. We found that, relative to national collegiate data (59.4 % female, 41.5 % URM), females were over-represented (63.4 %) and URM groups were under-represented (23.7 %) in these studies. Interventions improved sleep knowledge (g = 0.69, p<.001) and sleep quality (g = 0.25, p<.001), but not sleep duration (g = 0.13, p = .18). Effect sizes were similar in males, females, URM students, and non-URM students. There were no studies that incorporated financial, social, or neighborhood-level barriers to sleep in students.
