Abstract
BACKGROUND: Sleep and physical activity are inherent to human living, yet appear affected by Crohn's disease (CD), resulting in fatigue and disability. AIM: To objectively assess sleep quality and physical activity and their associations using accelerometers, comparing CD vs. matched healthy control (HC) subjects. METHODS: Exactly 49 CD and 30 HC subjects completed surveys encompassing self-reported fatigue and sleep quality, pathology testing and wore an accelerometer for 7 days, measuring physical activity and sleep. In this cross-sectional observational study, per-group comparisons were performed and in CD, factors associated with reduced activity and/or sleep quality were assessed via multivariate analyses. RESULTS: Regarding physical activity, CD subjects overall performed less total accelerometer counts (median 1.3 × 10(6) vs. 2.0 × 10(6) ), were more sedentary (97.7% vs. 96.2%) and completed fewer bouts of moderate-vigorous intensity exercise (1.0 vs. 5.0, each P < 0.01 (Mann-Whitney) than HC over 7 days. Factors associated with poor physical activity in CD included elevated serum CRP (OR = 22.6), lower vitamin D3 (OR = 13.1) and longer disease duration (OR = 1.2 per year, each P < 0.05). Regarding sleep, the CD group had similar total sleep time (median 458 vs. 447 min, P = 0.56), but more awakenings post-sleep onset (22 vs. 11, P = 0.01). Factors associated with severe sleep dysfunction in CD included lower haemoglobin (OR = 6.7) concurrent anti-TNF (OR = 6.5, each P < 0.05) and opioid therapy (OR = 6.6, P = 0.09). CONCLUSION: Utilising objective measurement in a habitual context over 7 days, patients with Crohn's disease exhibited poorer sleep quality and less physical activity than well-matched healthy controls.
