Prior Night Sleep Affects Next-Day Pain Interference Among Community-Dwelling Older Adults With Lower Extremity Chronic Pain

This is the authors' abstract. We don't add key points for this paper.

Emergent work suggests that sleep is a robust biobehavioral predictor of pain; however, it remains unclear how sleep is prospectively linked to pain on a day-to-day basis among older adults. The current prospective study examined how sleep duration (total sleep time), quality (sleep efficiency, wake after sleep onset), and late and irregular sleep timing influenced next-day pain perception among community-dwelling older adults ( N = 10; 65 matched observations) with lower extremity chronic pain over 1 week. Multilevel modeling estimated the association between sleep (Actigraph GT9X Link) and pain perception (Brief Pain Inventory Short Form). Increased wake after sleep onset (B = 0.19, p = 0.04), sleep variability (B = 0.02, p = 0.01), and later midsleep time (B = 0.40, p < 0.05) were associated with increased pain interference the following day. Findings support the idea that timely sleep interventions may reduce the effect of poor sleep on next-day pain in older adults. [ Research in Gerontological Nursing, 14 (4), 173–179.]
