“…Self-reported sleep duration often differs considerably from objective measures of sleep duration, and may underestimate or overestimate sleep duration compared to these other methods. [121][122][123] Polysomnography (PSG) and actigraphy were utilized as objective measures in some studies. Actigraphy has better sensitivity (detecting sleep) than specificity (detecting wake).…”

“…Moreover, the questionnaires used in the current study are well-validated instruments, and the self-report sleep measure (BIS) has been shown to correspond well with objective sleep measures, including polysomnography (PSG) [19]. Although self-reported sleep parameters typically differ from those obtained from objective assessments [27], recent studies have shown that such self-report sleep assessments can be recommended for the characterization of sleep parameters in both clinical and population-based research [28]. Still, the BIS has not been validated for sleep problems in pregnancy.…”

Objective: To examine if insomnia before and after childbirth predicts the development of postpartum bodily pain. Methods: This study is part of a longitudinal cohort study, the Akershus Birth Cohort Study, which targeted all women giving birth at Akershus University Hospital in Norway. The current sample is comprised of 1480 women who participated at all three time points, yielding a participation rate of 32% of the 4662 women who originally consented to participate. The Bergen Insomnia Scale (BIS) was used to measure insomnia and a latent profile analysis (LPA) was used to identify subsets of women who shared a similar pattern of responses on the BIS-scale across the three time points. Pain was measured using the bodily pain scale, derived from the Primary Care Evaluation of Mental Disorders (PRIME-MD) and symptoms of depression were measured by the Edinburgh Postnatal Depression Scale (EPDS). Results: Using a latent profile analysis a three class model showed the best fit and identified one major group (55.6%) with a low BIS scores across all three time points, one group with intermediate BIS scores (32.9%), and a smaller group (11.5%) with higher BIS scores across all three times. The chronic high insomnia group had a 2.8-fold increased risk of reporting high levels of bodily pain. The chronic intermediate group was associated with a 2.2-fold increased risk of bodily pain at two years postpartum. Adjusting for demographics and lifestyle behaviors did not reduce any of the associations, while adjusting for depression significantly attenuated the associations. Additional adjustment for pain at eight weeks postpartum further reduced the magnitude of the associations, but both chronic intermediate insomnia and chronic high insomnia remained strongly associated with the onset of bodily pain in the fully adjusted models (RR = 1.75, 95% CI: 1.37-2.23) and RR = 1.63, 95% CI: 1.15-2.32, respectively). Conclusions: The high prevalence of insomnia among women during and after childbirth, in combination with the strong prospective association with impaired physical health, emphasizes the importance of adequately identifying, preventing and treating insomnia for this population.

“…Although there is evidence to suggest wrist actigraphy is superior to actigraphy from a hip site in terms of correspondence with polysomnography, wrist actigraphy is based on upper extremity movement during sleep and tends to overestimate the amount of sleep and underestimate wakefulness. 14 Polysomnography, of course, would be necessary to capture more fully the sleep disturbances during stable and exacerbating states. However, the American Academy of Sleep Medicine does state that, in when polysomnography is not available, actigraphy is indicated as a method to estimate TST in patients with obstructive sleep apnea.…”

A longitudinal assessment of sleep variables during exacerbations of chronic obstructive pulmonary disease

Although sleep disturbance is common in chronic obstructive pulmonary disease (COPD), relatively little is known on the effect of the exacerbation on sleep quality. Accordingly, we longitudinally assessed sleep variables during exacerbations and clinical stability. This is a sub-study of a larger observational analysis. Inclusion criteria were clinically stable COPD and two or more clinical exacerbations in the preceding 12 months. Patients were followed for approximately 6 months and during this time the following were recorded daily: (1) COPD exacerbations, which were determined in two ways, clinically and symptom defined using the exacerbations of chronic pulmonary disease tool (EXACT); (2) daytime sleepiness, which was measured using the Stanford Sleepiness Scale; (3) subjective awakenings, which was measured from a sleep diary; and (4) sleep duration, efficiency, and objective awakenings, which was measured from actigraphy. These variables for exacerbation and non-exacerbation days were compared. Seventeen patients (9 male, age 63 + 12 years, forced expiratory volume in 1 second 52 + 20%) entered data over 135 + 18 days. During this time, 15 patients had 27 symptom-defined exacerbations and 8 had 9 clinically reported exacerbations. Symptom-defined exacerbation days were 26% of the total study days. More daytime sleepiness, decreased total sleep time (TST), and decreased sleep efficiency (SE) were present during exacerbations compared with clinical stability (p < 0.001). These disturbances tended to be greater during clinically reported exacerbations than during unreported events (p < 0.05). Increased daytime sleepiness, less TST, and poorer SE are present during COPD exacerbations.
