Abstract It is unknown if time-restricted feeding confers a protective effect on the physical function of older adults. The aim of this study was to assess prolonged nightly fasting in association with performance-based lower-extremity function (LEF) in a large population of community-dwelling older adults. A cross-sectional study was carried out among 1,226 individuals ≥64 years from the Seniors-ENRICA-II cohort. In 2016-2017, habitual diet was assessed through a validated diet history. Fasting time was classified into the following categories: ≤9, 10-11, and ≥12hours/day, the latter being considered prolonged nightly fasting. Performance-based LEF was assessed with the Short Physical Performance Battery (SPPB). After adjusting for potential confounders, a longer fasting period was associated with a higher likelihood of impaired LEF [odds ratio (OR) and 95% confidence intervals (CI) for the second and third categories: 2.27 (1.56-3.33) and 2.70 (1.80-4.04), respectively, considering the ≤9 hours/day fasting group as reference; p-trend <0.001]. When assessing each SPPB subtest separately, fasting time showed a significant association with balance impairment (OR for highest vs. lowest fasting time: 2.48; 95% CI: 1.51-4.08; p-trend =0.001) and difficulty to rise from a chair (OR for highest vs. lowest fasting time: 1.47; 95% CI: 1.05-2.06; p-trend =0.01). The risk associated with ≥12 h fasting among those with the lowest levels of physical activity was three times higher than among those with ≤9 hours fasting with the same low level of physical activity. Prolonged nightly fasting was associated with a higher likelihood of impaired LEF, balance impairment, and difficulty to rise from a chair in older adults, especially among those with low levels of physical activity.

Abstract Background: Time-restricted feeding, a specific form of intermittent fasting, has been associated with several possible health benefits including improved body composition, blood lipid levels and extended lifespan. However, it is unknown if time-restricted feeding confers a protective effect on the physical function of older adults. The aim of this study was to assess time-restricted feeding in association with performance-based lower-extremity function (LEF) in a large population of community-dwelling older adults.Methods: Cross-sectional study among 1,226 individuals ≥64 years from the Seniors-ENRICA-II cohort. In 2016-2017, habitual diet was assessed through a validated diet history. Fasting time was classified into the following categories: ≤9, 10-11, and ≥12hours/day, the latter being considered time-restricted feeding. Performance-based LEF was assessed with the Short Physical Performance Battery (SPPB).Results: After adjusting for potential confounders, a longer fasting period was associated with a higher likelihood of impaired LEF [odds ratio (OR) and 95% confidence intervals (CI) for the second and third categories: 2.27 (1.56-3.33); and 2.70 (1.80-4.04), respectively, considering the ≤9 hours/day fasting group as the reference category; p-trend <0.001]. When assessing each SPPB subtest separately, fasting time showed a significant association with balance impairment (OR for highest vs. lowest fasting time: 2.48; 95% CI: 1.51-4.08; p-trend= 0.001) and difficulty to rise from a chair (OR for highest vs. lowest fasting time: 1.47; 95% CI: 1.05-2.06; p-trend= 0.01).Conclusions: Time-restricted feeding was associated with a higher likelihood of impaired LEF, balance impairment, and difficulty to rise from a chair in older adults. These results need to be confirmed in further longitudinal studies.Trial registration: ClinicalTrials.gov NCT03541135. Registered 30 May 2018, retrospectively registered.

Abstract Early identification of functional decline in older adults with mild cognitive impairment (MCI) provides the opportunity to initiate behavioral interventions to slow decline. More frequent breaks in sedentary time has been associated with greater lower extremity function. This longitudinal study examined the effect of 6-month change in cognitive function on monthly sedentary time, controlling for lower extremity function, among community-dwelling older adults with MCI. Twenty adults with Montreal Cognitive Assessment Score (MoCA) between 19-25, who were age ≥ 60 years old, and ambulatory, wore an actigraph for 6 months and participated in monthly in-person assessments. Measures included MoCA change (baseline to month 6), Short Physical Performance Battery (SPPB; baseline, months 3 and 6); sedentary time and physical activity intensity; and falls (monthly). The sample was 70% female, 60% non-Hispanic white, with a mean age of 77 years. Sixteen participants provided complete data for mixed-model analysis. Over 6 months, 11 falls occurred among 7 participants. The mean MoCA score declined from 22.7 to 21.9 while SPPB remained stable. Overall time spent in sedentary behavior was high (71%) and physical activity intensity was low (light and moderate combined= 26.1%). Results of multi-level analysis with sedentary time as a continuous Level-1 variable and MoCA change scores, SPPB scores, and age in Level-2 showed that negative change in MoCA (β=-0.11; p≤0.05) was associated with increased sedentary time. Given sedentary time increases as cognitive function declines, older adults with MCI could benefit from interventions designed to interrupt sedentary time as well as increase physical activity.

Community Dwelling Older Adults

Dementia is prevalent in worldwide, and increases the care burden and potential costs. Physical activity (PA) has been increasingly shown to be beneficial for them. This was a cross-sectional observational study aiming to investigate the status of PA among community-dwelling older adults with dementia in Beijing or Hangzhou, China, and verify the relationships between neuropsychiatric symptoms, activities of daily living (ADL), caregivers’ fear of patients’ falling and their PA using a path analysis approach. The level of PA among 216 included people with dementia was low. PA was related to the neuropsychiatric symptoms, with ADL and caregivers’ fear of patients’ falling have mediation roles. The findings indicated that person-centered strategies related to the management of these symptoms might be helpful to improve ADL, relieve caregivers’ concerns about them falling and consequently foster positive participation in PA.

Community Dwelling Older Adults

Older adults’ physical activity (PA) is low. We examined whether eight months of resistance training increased PA level in community-dwelling older adults receiving home care. A two-armed cluster-randomized trial using parallel groups was conducted. The included participants were >70 years and received home care. The resistance training group performed resistance training using body weight, elastic bands, and water canes twice per week for eight months. The control group was informed about the national PA guidelines and received motivational talks. The ActiGraph GT3X+ accelerometer was used to estimate PA. Outcomes included total PA (counts per minute), sedentary behavior (min/day), light PA (min/day), moderate-to-vigorous PA (min/day), and steps (mean/day). Between-group differences were analyzed using multilevel linear mixed models. Twelve clusters were randomized to either resistance training (7 clusters, 60 participants) or the control group (5 clusters, 44 participants). A total of 101 participants (median age 86.0 (interquartile range 80–90) years) had valid accelerometer data and were included in the analysis. There were no statistically significant between-group differences for any of the PA outcomes after four or eight months. This study offers no evidence of increased PA level following resistance training in older adults with home care.
