ATS 2013, PHILADELPHIA ─ The negative effects of poorly controlled asthma symptoms on sleep quality and academic performance in urban schoolchildren has been confirmed in a new study.
"While it has been recognized that missed sleep and school absences are important indicators of asthma morbidity in children, our study is the first to explore the associations between asthma, sleep quality, and academic performance in real time, prospectively, using both objective and subjective measures," said principal investigator Daphne Koinis-Mitchell, PhD, Associate Professor of Psychiatry & Human Behavior (Research) and Associate Professor of Pediatrics (Research) at Brown University's Alpert Medical School in Providence, Rhode Island. "In our sample of urban schoolchildren (aged 7 to 9), we found that compromised lung function corresponded with both poor sleep efficiency and impaired academic performance."
The results of the study will be presented at the American Thoracic Society's 2013 International Conference.
The study included data on 170 parent-child dyads from urban and African-American, Latino, and non-Latino white backgrounds who reside in Greater Providence, RI. These data are part of a larger 5-year study of asthma and allergic rhinitis symptoms, sleep quality and academic performance (which will include 450 urban children with persistent asthma and healthy controls) funded by The Eunice Kennedy Shriver National Institute of Child Health and Human Development. Project NAPS (Nocturnal Asthma and Performance in School) is administered through Rhode Island Hospital at The Bradley Hasbro Research Center.
Asthma symptoms were assessed over three 30-day monitoring periods across the school year by spirometry, which measures the amount and speed of exhaled air, and with diaries maintained by children and their caregivers. Sleep quality was assessed with actigraphy, which measures motor activity that can be used to estimate s
