| Annotation | Many nursing home (NH) residents have disrupted sleep and circadian rhythms. The authors examined the impact of a multi-component non-pharmacological intervention on 24-hour rest and activity rhythms in long-stay NH residents. The study was a randomised controlled trial in which following a 3-day baseline, participants received 3 days of either usual care (control condition) or the active intervention. The intervention combined increased exposure to outdoor bright light, efforts to keep residents out of bed during the day, structured physical activity, institution of a bedtime routine, and efforts to reduce nighttime noise and light in residents' rooms. For 100 residents with baseline and follow-up wrist actigraphy data (mean age 87 and 76% women), rest/activity rhythms were modelled to determine the rhythm acrophase (peak time), nadir (trough time), midline estimating statistics of rhythm (MESOR/ midpoint), amplitude (designation of peak), slope, and the rest period/active period ratio. The intervention led to an increase in the duration of the "active" portion of the rhythm, which was primarily accounted for by a shift in the rest/activity rhythm rise to an earlier time. Findings persisted when analyses were adjusted for age, cognitive functioning, medical comorbidities, and behavioural disturbances. These findings suggest that the intervention may effectively improve the robustness of rest/activity rhythms of NH residents. (RH). |
