Asthma Control and Its Relationship with Obstructive Sleep Apnea (OSA) in Older Adults.

Background/Objectives. Asthma in older individuals is poorly understood. We aimed to characterize the older asthma phenotype and test its association with obstructive sleep apnea (OSA).

Sleep duration, asthma and obesity.

Background: Obesity is more prevalent in asthmatics. Sleep duration is a novel risk factor for obesity in general populations.

Objective: We tested the association of sleep duration and asthma characteristics with obesity.

Association of obstructive sleep apnea risk or diagnosis with daytime asthma in adults.

Objective: Obstructive sleep apnea (OSA) worsens nocturnal asthma, but its potential impact on daytime asthma remains largely unassessed. We investigated whether the sleep disorder is associated with daytime, in addition to nighttime, asthma symptoms.

Methods: Asthma patients at tertiary-care centers completed the Sleep Apnea scale of the Sleep Disorders Questionnaire (SA-SDQ), and an asthma control questionnaire.

Association of obstructive sleep apnea risk with asthma control in adults.

Background: Unrecognized obstructive sleep apnea (OSA) may lead to poor asthma control despite optimal therapy. Our objective was to evaluate the relationship between OSA risk and asthma control in adults.

Methods: Patients with asthma seen routinely at tertiary-care clinic visits completed the validated Sleep Apnea Scale of the Sleep Disorders Questionnaire (SA-SDQ) and Asthma Control Questionnaire (ACQ).
