Study: Bedtime regularity predicts CPAP compliance

Wednesday, May 8, 2013

DARIEN, Ill. – Having a routine bedtime prior to CPAP therapy plays an important role in compliance, suggests a new study published in the journal SLEEP. Conducted by researchers at Penn State University, the study found that bedtime variability was a significant predictor in CPAP adherence, which researchers defined as four or more hours of treatment per night. The odds of not being adherent to CPAP therapy after one month were 3.7 times greater for every one unit increase in pre-treatment bedtime variability, the study found. “Long-term use of CPAP, such as after the first month or longer, requires regular routines that are conducive to establishing a new health behavior,” stated principal investigator Amy Sawyer, PhD, RN, assistant professor at the Penn State School of Nursing. Researchers will present the findings of the study, which comprised 97 adults with newly diagnosed obstructive sleep apnea (OSA), at the SLEEP 2013 professional conference June 5 in Baltimore.
