Insomnia, Sleep Apnea Common in Veterans with OA

BMC Musculoskelet Disord; ePub 2018 Mar 9; Taylor, et al

Insomnia and obstructive sleep apnea (OSA) symptoms were very common in veterans with osteoarthritis (OA), according to a recent study, and a substantial proportion of individuals with symptoms may have gone undiagnosed. In addition, characteristics associated with insomnia and OSA symptoms were consistent with prior studies. Veterans (n=300) enrolled in a clinical trial completed the Insomnia Severity Index (ISI) and the Berlin Questionnaire (BQ) at baseline; proportions of participants with symptoms consistent with insomnia and OSA were calculated. Researchers found:

  • Symptoms consistent with insomnia and OSA were found in 53% and 66% of this sample, respectively.
  • Among participants screening positive for insomnia and OSA, diagnosis codes for these disorders were present in the electronic medical record for 22% and 51%, respectively.
  • Characteristics associated with insomnia were lower age, having a PTSD diagnosis, greater pain severity, and greater depressive symptoms.
  • Characteristics associated with OSA were higher BMI, greater depressive symptoms, and opioid use.
