..Asthma was identified by self-report. Habitual hours of sleep duration were categorized as short (≤5), normal (6-8), and long (≥9). Multivariate regression analyses were used to examine the associations between sleep duration and patient-reported outcomes and healthcare use.
Of the 1389 adults with asthma, 26% reported short sleep duration, 66% reported normal sleep duration, and 8% reported long sleep duration. Those with short sleep duration had increased asthma attacks (aOR 1.58, 95% CI 1.13-2.21), coughing (aOR 1.95, 95% CI 1.32-2.87), and overnight hospitalizations (aOR 2.14, 95% CI 1.373.36) compared with those with normal sleep duration.
They also reported worse health-related quality of life including days of poor physical health, mental health, and inactivity due to poor health (p-values <.05). Those with long sleep had more activity limitation due to wheezing compared to those with normal sleep (aOR 1.82, 95% CI 1.13-2.91).
Compared to adults with asthma and normal sleep duration, those with short sleep duration experience more frequent asthma attacks, increased healthcare use, and worse health-related quality of life, whereas those with long sleep duration experience more frequent activity limitation.
