“…The results of our present analyses demonstrate that SL accounted for 23.2% of hospitalized older adults’ daily physical activity, which is a larger proportion than that of community-dwelling older adults [ 13 , 14 ]. Our correlation analyses revealed a trade-off relationship between SL and SB, and SL and SB showed different trends in relation to physical function.…”

“…According to the results of measurements using self-reporting [ 13 ] and non-METs devices in community-dwelling older adults [ 14 ], the daytime lying-down time ranged from 7.7% to 17.4%, which is less than the corresponding values reported in hospitalized older adults. Thus, the amount of SL time is low among community-dwelling older adults.…”

Sleep Should Be Focused on When Analyzing Physical Activity in Hospitalized Older Adults after Trunk and Lower Extremity Fractures—A Pilot Study

Although the importance of resting in bed for hospitalized older adults is known, current methods of interpreting physical activity (PA) recommend the use of a broad definition of sedentary behavior (SB) that includes 0–1.5 metabolic equivalents (METs) of sleep (SL) and sitting. We investigated the characteristics of PA by conducting a cross-sectional study of 25 older adults with trunk and lower extremity fractures. The intensity of their PA was interpreted as SL (0–0.9 METs), SB (1–1.5 METs), low-intensity PA (LIPA: 1.6–2.9 METs), and moderate-to-vigorous PA (MVPA: >3.0 METs). We calculated the correlation coefficients to clarify the relationship between each PA intensity level. Our analyses revealed that the PA time (min/day) was accounted for by SB (53.5%), SL (23.2%), LIPA (22.8%), and MVPA (0.5%). We observed negative correlations between SL and SB (r = −0.837) and between SL and LIPA (r = −0.705), and positive correlations between SB and LIPA (r = 0.346) and between LIPA and MVPA (r = 0.429). SL and SB were also found to have different trends in relation to physical function. These results indicate that SL and SB are trade-offs for PA during the day. Separate interpretations of the SL and SB of older hospitalized adults are thus recommended.

[Purpose] To identify factors that affect the return to solitary living of patients with stroke who had lived alone prior to stroke onset. [Participants and Methods] From January 2017 to March 2020, we enrolled a total of 103 patients with stroke who had lived alone prior to stroke onset and retrospectively analyzed their age, gender, length of hospital stay, outcome (return to living alone or not), functional independence measure at discharge, and social score at discharge. We also analyzed the relationship between the above factors and the outcome. [Results] Functional independence measure and social score at discharge were significantly associated with the outcome. The cutoff value of the functional independence measure at discharge was 91 (area under the curve: 0.91; sensitivity: 0.96; specificity: 0.72), while the rate of return to living alone was 23.5% when the social score was ≥3. The sensitivity and specificity for return to living alone were 0.91 and 0.88, respectively, when cutoff values of the functional independence measure and social score at discharge were 91 and 3, respectively. [Conclusion] Social factors and ability to perform activities of daily living are important for return to solitary living for patients with stroke who lived alone prior to stroke onset.

Objective: Few studies have detailed the physical activity and postural patterns (e.g. lying or sitting) in older adults with declining activities of daily living (ADL). Therefore, we aimed to address this issue by quantifying physical activity using an accelerometer and measuring time spent in various postures among older adults in assisted-living residences. Methods: We quantified physical activity using an accelerometer (ActivPAL) and measured time spent in various postures in 35 older adults (mean age: 89.1 years) with chronic conditions residing in two assisted-living residences in Japan. ActivPAL was attached to the thigh and trunk of patients to distinguish between sitting and lying postures. Results: Participants had a mean count of 6.2 comorbidities, and they were divided into three groups (fully independent, requiring minimal assistance and requiring care) based on their activities of daily living capacity using the Barthel Index. Residents aged ⩾90 years walked a mean of 1109.1 steps and spent 167.3 min upright per day. Fully independent participants walked a mean of 3587.6 steps daily; those requiring minimal assistance walked 1681.0 steps daily; and those requiring care walked 428.9 steps daily. Conclusions: Our findings indicated that step count, number of sit-to-stand transitions, stepping time, and upright time decreased significantly as activities of daily living capacity decreased. Comorbidity type and number of comorbidities were not related to their lying time except for depression status. Lying time was associated with depression status.
