Habitual Physical Activity and Sleep Duration in Institutionalized Older Adults

Abstract

Background: Physical activity and sleep quality are both major factors for improving one's health. Knowledge on the interactions of sleep quality and the amount of physical activity may be helpful for implementing multimodal health interventions in older adults.Methods: This preliminary cross-sectional study is based on 64 participants [82.1 ± 6.4 years (MD ± SD); 22 male: 42 female]. The amount of physical activity was assessed by means of an accelerometer (MyWellness Key). Self-reported sleep parameters were obtained using the Pittsburgh Sleep Quality Index. The Barthel Index was used for physical disability rating. Bivariate correlations (Spearman's Rho) were used to explore relationships between the amount of physical activity and sleep quality. To analyse differences between categorial subgroups univariate ANOVAs were applied; in cases of significance, these were followed by Tukey-HSD post-hoc analyses.Results: No linear association between physical activity and sleep quality was found (r = 0.119; p > 0.05). In subgroup analyses (n = 41, Barthel Index ≥90 pts, free of pre-existing conditions), physical activity levels differed significantly between groups of different sleep duration (≥7 h; ≥6 to <7 h; ≥5 to <6 h; <5h; p = 0.037).Conclusion: There is no general association between higher activity levels and better sleep quality in the investigated cohort. However, a sleep duration of ≥5 to <6 h, corresponding to 7.6 h bed rest time, was associated with a higher level of physical activity.

Multimodal Exercise Effects in Older Adults Depend on Sleep, Movement Biography, and Habitual Physical Activity: A Randomized Controlled Trial

“…Consequently, beyond being an effector or outcome in intervention studies, sleep duration is related to physical activity (McClain et al, 2014;Mendelson et al, 2016). In addition, old age habitual physical activity is predicted by movement biography (Vogel et al, 2021a). According to that, sleep parameters and physical activities are not exclusively related to healthy aging, but exhibit mutual interactions and assumingly respond to multicomponent interventions.…”

Use of daily posture and activity tracking to assess sedentary behavior, toss-and-turns, and sleep duration of independently living Thai seniors

“…44 Nevertheless, no association was found between high activity levels and better sleep quality for independently living elders. These healthy people with the highest PA level per week had a sleep duration of ≥5 and <6 h. 5…”

“…44 Nevertheless, no association was found between high activity levels and better sleep quality for independently living elders. These healthy people with the highest PA level per week had a sleep duration of ≥5 and <6 h. 5 To examine these complicated relationships and provide additional evidence on the seniors living independently in a Thai nursing home, we propose the following hypothesis: Hypothesis 1. Sedentary behaviors affect sleep duration, regardless of health condition.…”

“…Mental health employs the validated depression scale, Depress 9Q, which consists of 9 questions developed by the Department of Mental Health, the Ministry of Public Health in Thailand. PHSES, Health 6 m, and Depress 9Q used the 5-points rating scale (1)(2)(3)(4)(5). Fall 2 year asked whether the elder had a fall experience in the past 2 years.…”

“…Nevertheless, recent research still reported mixed results between physical activity, sleep duration, and sleep quality. [5][6][7][8] Moreover, there is a need to determine the relationship between physical activity, restlessness during daytime naps, nighttime sleep duration, and successful aging. 9 Thus, this study aims to determine whether sedentary behavior affects a senior's sleep duration.…”
