Study Finds Prevalence of Insomnia in Patients with Asthma
A recent study found a high prevalence of clinical insomnia in individuals with asthma. In addition, the study also determined the effects of insomnia on the well-being, asthma control, and asthma-related health care utilization of patients. Researchers concluded that insomnia is highly prevalent in individuals with asthma, and those with insomnia experience adverse health effects and are at risk for not having well-controlled asthma.
A team of researchers, lead by Faith S. Luyster at the University of Pittsburg, studied the prevalence of insomnia in patients with asthmas to determine its association with asthmas and the health of the patient by using the Insomnia Severity Index, Asthma Control Test, Asthma Quality of Life Questionnaire, and Hospital Anxiety and Depression Scale. The study collected data from 714 participants confirmed with asthma and enrolled in the Severe Asthmas Research Program III.

Researchers identified insomnia in 263 participants (37%). Insomnia in patients increased their risk for not having well-controlled asthma by 2.4-fold and their risk for asthma-related health care utilization by 1.5-fold in the past year compared to patients without insomnia. Patients with insomnia also showed higher levels of anxiety and depression, as well as poor quality of life.
While patients with asthma commonly report sleep difficulties, the relationship between asthma and insomnia is unknown. The researchers concluded, “Insomnia is highly prevalent in asthma and is associated with adverse outcomes. Further studies are needed to gain a better understanding of the interaction between insomnia and asthma control.”
