Abstract

Purpose There is limited information on the association between pre-treatment insomnia symptoms and dysfunctional sleep beliefs with continuous positive airway pressure (CPAP) adherence in veterans with obstructive sleep apnea (OSA). Our aims were to describe demographic and sleep characteristics of veterans with and without comorbid insomnia and determine whether pre-treatment insomnia symptoms and dysfunctional sleep beliefs predict CPAP use after 6 months of therapy.Methods Hispanic veterans attending the Miami VA sleep clinic were recruited and completed the insomnia severity index, the dysfunctional sleep belief and attitude scale (DBAS), and other questionnaires. Participants were asked to return after 7 days and 1 and 6 months to repeat questionnaires and for objective CPAP adherence download. Hierarchical regression models were performed to determine adjusted associations of pre-treatment insomnia symptoms and DBAS sub-scores on 6-month mean daily CPAP use.Results Fifty-three participants completed the 6-month follow-up visit with a mean CPAP use of 3.4 ± 1.9 h. Veterans with comorbid insomnia had lower mean daily CPAP use (168 ± 125 vs 237 ± 108 min, p = 0.04) and lower percent daily CPAP use ≥ 4 h (32 ± 32 vs 51 ± 32%, p = 0.05) compared to participants without insomnia. In adjusted analyses, pre-treatment insomnia symptoms (early, late, and aggregated nocturnal symptoms) and sleep dissatisfaction were predictive of lower CPAP use at 6 months. Pre-treatment dysfunctional sleep beliefs were not associated with CPAP adherence.Conclusions Pre-treatment nocturnal insomnia symptoms and sleep dissatisfaction predicted poorer 6- month CPAP use. Insomnia treatment preceding or concurrent with CPAP initiation may eliminate a barrier to regular use.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Since 2017, a number of other studies have confirmed associations between COMISA and increased depressive and anxiety symptoms, daytime sleepiness, reduced quality of life, neurocognitive performance, and sleep quality compared to patients with either insomnia or OSA alone.

    “Since 2017, a number of other studies have confirmed associations between COMISA and increased depressive and anxiety symptoms, daytime sleepiness, reduced quality of life, neurocognitive performance, and sleep quality compared to patients with either insomnia or OSA alone [46,47,48,49,50,51,52].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
