Nocturnal Awakenings and Asthma Control in Urban School-Age Children

This study evaluated the extent to which the sleep is disrupted by nighttime awakenings in urban children with and without asthma and examined racial/ethnic differences in sleep outcomes. Three hundred and seventy-nine urban children aged 7 to 9 years with (n = 250) and without (n = 129) asthma were included. Participants were 45% Latino, 34% black, and 21% non-Latino white (NLW). Nighttime awakenings were assessed via actigraphy. Asthma status was assessed by a clinically and via self-report. Children with asthma had significantly more awakenings than those without. Latino children with asthma had more and longer awakenings compared to Latino children without asthma; these effects were not observed among black or NLW participants. Poor asthma control was associated with more awakenings. Urban children face higher risks for poor sleep and asthma outcomes. Multicomponent interventions addressing asthma management and culturally tailored sleep hygiene strategies are necessary to improve asthma and sleep outcomes in this highly burdened population.
