    OBJECTIVE: To determine the impact of a cognitive behavioral pain management program on sleep in patients with chronic pain. DESIGN: Prospective nonrandomized controlled pilot study with evaluations at baseline and 12 weeks.SETTING: Out-patient multidisciplinary cognitive behavioral pain management program in a university teaching hospital.SUBJECTS: Patients with chronic pain who fulfilled the criteria for participation in a cognitive behavioral pain management program.METHODS: Patients assigned to the intervention group (n = 24) completed a 4 week cognitive behavioral pain management program, and were compared with a waiting list control group (n = 22). Assessments for both groups occurred at baseline and two months post cognitive behavioral pain management program. Outcome measures included self-report (Pittsburgh Sleep Quality Index) and objective (actigraphy) sleep measures, pain and quality of life measures.RESULTS: Both groups were comparable at baseline, and all had sleep disturbance. The Pittsburgh Sleep Quality Index correlated with only two of the seven objective sleep measures (fragmentation index r = 0.34, P = 0.02, and sleep efficiency percentage r = -0.31, P = 0.04). There was a large treatment effect for cognitive behavioral pain management program group in mean number of wake bouts (d = 0.76), where a significant group*time interaction was also found (P = 0.016), showing that the CBT-PMP group improved significantly more than controls in this sleep variable. CONCLUSIONS: Patients attending a cognitive behavioral pain management program have high prevalence of sleep disturbance, and actigraphy technology was well tolerated by the patients. Preliminary analysis of the impact of a cognitive behavioral pain management program on sleep is promising, and warrants further investigation.

    Obesity is associated with numerous chronic diseases, including musculoskeletal (MSK) pain, which affects on quality of life (QoL). There is, however, limited research providing a comprehensive MSK pain profile of an obese cohort. This retrospective study used a patient database at a national weight management service. After ethical approval, anonymized patient data were statistically analyzed to develop a pain profile, investigate relationships between pain, sleep, and function, and explore variables associated with having low back pain (LBP) and knee pain. Overall, 915 individuals attended the weight management service from January 2011 to September 2015 [male, 35% (n = 318; confidence interval [CI] = 32-38); female, 65% (n = 597; CI = 62-68); mean age 44.6]. Mean body mass index was 50.7 kg/m 2 [class III obese (body mass index ≥40 kg/m 2), 92% (n = 835; CI = 91-94)]. Approximately 91% reported MSK pain: LBP, 69% (n = 539; CI = 65-72) [mean Numeric Rating Scale 7.4]; knee pain, 58% (n = 447; CI = 55-61) [mean Numeric Rating Scale 6.8]. Class III obese and multisite pain patients had lower QoL and physical activity levels, reduced sleep, and poorer physical function than less obese patients and those without pain (P < 0.05). Relationships were found between demographic, pain, self-report, psychological, and functional measures (P < 0.05). Patients who slept fewer hours and had poorer functional outcomes were more likely to have LBP; patients who were divorced, had lower QoL, and more frequent nocturia were more likely to have knee pain (P < 0.05). Multisite MSK pain is prevalent and severe in obese patients and is negatively associated with most self-report and functional outcomes. This high prevalence suggests that pain management strategies must be considered when treating obesity.
