Association Between Moderate Physical Activity Level and Subsequent Frailty Incidence Among Community-Dwelling Older Adults: A Population-Based Cohort Study

Abstract Background The evidence concerning longitudinal association between physical activity (PA) and frailty is scarce, and variation in the scales, tools, or modules of PA made it challenging to obtain consistent results. This association among the individules who reached an older age where age-related cumulative chronic diseases and physical function declines were common, was unclear. Our study aimed to demonstrate the association between PA and frailty incidence among Japanese community-dwelling older adults with narrow age range of 70–74 years. Mothods: About 485 participants aged 70–74 years from the Japan Gerontological Evaluation Study were included in this study. Frailty was assessed at baseline and 3 years later by using the Kaigo-Yobo Checklist. PA was assessed using the short-term International Physical Activity Questionnaire. Logistic regression was performed to calculate relative risk (RR) with 95% confidence intervals (CIs) after adjusting for potential confounders. Results After a 3-year follow-up, 46 new frailty cases were recorded. The association of frailty incidence with both PA volume and daily walking time presented a U-shaped curve, albeit statistically insignificant. After adjusting for potential confounders, walking for 0.5–1 h/d displayed a greater association with decreased frailty risk (OR, 0.35; 95% CI, 0.12–0.98) than higher levels of daily walking time. No association between PA volume and subsequent frailty was observed. Conclusions Incorporating moderate regular walking levels of 0.5–1 h/d in older adults may delay the onset of frailty and improve the aging process. Further studies are needed to investigate the effect of higher PA levels on frailty risk.

Abstract Background Previous studies reported that physical activity (PA) could prevent frailty, but the longitudinal evidence between PA volume and frailty is scarce. Additionally, the impact of daily walking time on the risk of frailty is unclear. This study aimed to examination the association of incident frailty with PA volume and daily walking time among Japanese community-dwelling older adults. Methods About 485 participants aged 70–74 years from the Japan Gerontological Evaluation Study were included in this study. Frailty was assessed at baseline and 3 years later by using the Kaigo-Yobo Checklist. PA was assessed using the short-term International Physical Activity Questionnaire. Logistic regression was performed to calculate relative risk (RR) with 95% confidence intervals (CIs) after adjusting for potential confounders. Results After 3 years of follow-up, 46 new frailty cases were recorded. The association of frailty incidence with both PA volume and daily walking time presented a U-shaped curve, albeit not statistically significant. After adjusting for potential confounding factors, walking for 0.5–1 h per day displayed a greater association with decreased frailty risk (RR, 0.35; 95% CI, 0.12–0.98) than higher levels of daily walking time. We did not observe an association between PA volume and subsequent frailty. Conclusions Walking for 0.5–1 hour/day significantly decreases frailty risk. Incorporating a moderate level of regular walking into the daily lives of older adults may postpone the onset of frailty and improve the ageing process. Further studies are needed to investigate the impact of higher PA levels on frailty risk.

Frailty is defined as a state of increased vulnerability due to age-related decline in reserve and function across multiple physiological systems. Increasing physical activity level is considered to be a measure to counteract frailty. Some studies have indicated that pet owners are more engaged in physical activity than non-owners. We conducted a systematic review regarding associations between pet ownerships and frailty among community-dwelling older adults and critically assessed the findings. PubMed was searched in April 2020 according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines for cross-sectional or prospective studies examining associations between pet ownership and frailty in community-dwelling older adults with a mean age of 60 or above. A supplementary search was done using Google Scholar. Identified articles were reviewed by two investigators independently and assessed for methodological quality. The search identified 48 studies, among which three studies (two cross-sectional and one prospective) were included in this review. These studies suggested that pet ownership may be associated with a lower risk of frailty. This systematic review found only a limited amount of relevant research. More research is needed to establish the link between pet ownership and frailty as well as healthy aging and well-being.

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.

Abstract Background: In this manuscript, we aimed at investigating whether objectively measured lifestyle factors, including walking steps, sedentary time, amount of unforced physical activity, level of slight and energetic physical activity, conversation time, and sleep parameters altered before and during the COVID-19 pandemic among community-dwelling older adults.Methods: Data were obtained from a prospective cohort study conducted from 2015 to 2019 and a subsequent dementia prevention study undertaken in September 2020. Community-dwelling adults aged ≥65 years wore wearable sensors before and during the pandemic.Results: A total of 56 adults were enrolled in this study. The mean age was 74.2±3.9 years, and 58.9% (n=33) of the participants were female. The moderate and vigorous physical activity time significantly decreased and sedentary time significantly increased during the pandemic. Conclusions: This is the first study to demonstrate differences in objectively assessed lifestyle factors before and during the COVID-19 pandemic among community-dwelling older adults. The findings show that the pandemic has adversely affected physical activity among older adults living on their own in Japan.

Background and objective: Both low and high body mass index (BMI) have been associated with greater mortality in older adults. This study evaluated the trajectory of BMI in the final years of life. Design: Population-based cohort study. Setting: Community-dwelling adults in the English Longitudinal Study of Ageing between 1998 and 2012. Measurements: Body mass index, years before death and all-cause mortality. Analyses were adjusted for age, gender, educational level, housing tenure and social class. Results: Data were analysed for 16,924 participants with 31,857 BMI records; mean age at study start, 61.6 (SD 10.9) years; mean BMI, 27.5 (4.7) Kg/m2. There were 3,686 participants (4,794 BMI records) who died and 13,238 participants (27,063 BMI records) who were alive at last follow-up. Mean BMI increased with age to 60-69 years but then declined, but the age-related decline was more rapid in decedents. At ages 80-89 years, mean BMI in decedents was 26.1 (4.7) compared with 27.1 (4.4) Kg/m2 in survivors. After adjusting for age and covariates, mean BMI declined in the five years before death. From 9 to 5 years before death or end of study, adjusted mean BMI was 0.51 (95% confidence interval 0.24 to 0.78) Kg/m2 lower for decedents than survivors; and from four to zero years before death, 1.55 (1.26 to 1.84) Kg/m2 lower in decedents. Conclusions: In community-dwelling older adults, mean body mass index enters an accelerating decline during five years before death. Reverse causation may account for the association of lower BMI with mortality.

Gender Specific

Research suggests that both nutrition and physical activity can protect mobility in older adults, but it is yet to be determined whether these relationships are affected by gender. Thus, we investigated the gender-specific relationship between nutritional status, physical activity level and functional mobility in Irish older adults. A cross-sectional study was undertaken in 176 community-dwelling older adults (73.6 ± 6.61 years) living in Cork, Ireland. Nutritional status was measured using the Mini Nutritional Assessment-Short Form (MNA-SF) and physical activity was assessed via the Physical Activity Scale for the Elderly (PASE). Functional mobility was measured using the Timed Up and Go (TUG) test. The gender-stratified relationship between variables was assessed using Pearson’s correlations and multiple linear regression. Partial correlations (p < 0.05) were observed for TUG with PASE score in both genders, and with MNA-SF score in females, only. Multiple regression showed that physical activity was a predictor of TUG in both genders (β = 0.257 for males, β = 0.209 for females, p < 0.05), while nutritional status was a predictor of TUG in females, only (β = −0.168, p = 0.030). Our results suggest that physical activity is associated with functional mobility in both genders, while the relationship between nutritional status and mobility may be specific to older females. These findings may be of interest for the design of functional preservation strategies.

Significant Difference

This study sought to investigate the prevalence of physical inactivity and related barriers in older Brazilian adults. A cross-sectional, population-based study was conducted, and a stratified random sampling procedure was used. A total of 359 older adults were interviewed. The long version of the International Physical Activity Questionnaire (IPAQ) and the Questionnaire of Barriers to Physical Activity Practice were used to assess physical activity level and barriers, respectively. No statistically significant difference was observed on the prevalence of physical inactivity in either gender or age groups. Regarding barriers, the proportion of 9 out of 22 barriers was statistically significant between men and women. Self-reported physical inactivity/activity in older Brazilian adults continues to be a concern. Uncommonly, older males reported a higher prevalence of physical inactivity compared to their counterparts. Additionally, physical inactivity prevalence continued to increase with the aging process. Yet, personal barriers such as lack of time and poor health were strongly associated with physical inactivity. The results of this study may help health professionals and public policy makers to better address the issues related to a healthy lifestyle among older adults and promote physical activity among Brazilian older adults and in other countries with similar characteristics.

Community Dwelling Older Adults

Abstract Background and Purpose. Few tests have been found to be strongly predictive of falls in community-dwelling older adults. The purpose of this study was to determine whether data from 5 balance tests—combined with data regarding fall history, number of medications, dizziness, visual problems, use of an assistive device, physical activity level, sex, and age—could predict falls in community-dwelling older adults who were independent. Subjects. Ninety-nine community-dwelling older adults aged 65 to 90 years (X̄= 74.02, SD=5.64) were tested. Methods. Subjects were tracked for falls over a 1-year period following testing. Impairment-based tests, which are tests that attempt to specifically identify which sensory systems are impaired or how motor control is impaired (eg, speed, accuracy of movement), were the Modified Clinical Tests of Sensory Interaction for Balance (Modified CTSIB) and the 100% Limits of Stability Test, both of which were done on the Balance Master 6.1. Performance-based tests, which are functional tests that identify functional limitations without necessarily identifying their causes, were the Berg Balance Scale, the Timed “Up & Go” Test, and the Dynamic Gait Index. Demographic and health data included age, sex, number of medications, physical activity level, presence of dizziness, vision problems, and history of falls over the previous year. Logistic regression was used to determine which combinations of data from balance tests, demographics, and health factors were predictive of falls. Results. Two models—(1) the “standing on a firm surface with eyes closed” (FEC) condition of the Modified CTSIB and (2) the FEC combined with age and sex—were predictive of falls, but predicted only 1 and 2 subjects who were at risk for falling, respectively, out of 20 people who were at risk for falling. Discussion and Conclusion. Five balance tests combined with health and demographic factors did not predict falls in a sample of community-dwelling older adults who were active and independent.
