Factors associated with going outdoors frequently: a cross-sectional study among Swiss community-dwelling older adults

Factors Associated With Outdoor Frequency Among U.S. Community-Dwelling Medicare Beneficiaries: A Cross-Sectional Study

PURPOSE

Despite the benefits of outdoor activity in older adults, a paucity of research explores factors associated with the frequency of older adults going outdoors. The aim of the current study was to investigate if factors of cognitive status, physical performance, and neighborhood characteristics were associated with outdoor frequency among older adults.

METHOD

This cross-sectional study used National Health and Aging Trends Study data to characterize outdoor frequency among Medicare beneficiaries by participant demographics, health, and neighborhood characteristics, and estimated relationships between participant factors and outdoor frequency.

RESULTS

The sample included 3,368 participants. The majority (51.6%) were aged 75 to 84 years and female (57.2%). Most (60.4%) participants went outside daily. Probable dementia, physical limitations, and presence of street disorder and sidewalk continuity were associated with decreased outdoor frequency.

CONCLUSION

Research is needed to develop interventions addressing neighborhood conditions and promoting outdoor activity among older adults living with dementia and physical limitations. [Research in Gerontological Nursing, 18(1), 40-52.].

The potential of lower limb exoskeletons to enhance life-space mobility and to leverage green exercise in the rehabilitation of older adults: an expert perspective

PURPOSE

As the global population aged 60+ grows, ensuring mobility and independence for older adults is a critical public health goal. This paper examines barriers to life-space mobility in older adults and explores wearable lower limb exoskeletons (LLEs) and green exercise as innovative solutions.

METHODS

Literature search and interdisciplinary expert input were utilized.

RESULTS

Life-space mobility, the physical space individuals move through daily, is often restricted by physical and environmental barriers, leading to increased dependency, depression, and reduced quality of life. LLEs offer promising support by compensating for decreased intrinsic capacities, thus facilitating outdoor mobility. Green exercise (i.e., physical activity in nature) provides mental and physical health benefits, further promoting mobility and well-being.

CONCLUSION

Combining LLEs with green exercise may create powerful rehabilitation modalities, addressing both physical and mental aspects of aging. Integrating life-space mobility research into exoskeleton development and rehabilitation programs ensures these solutions meet real-world needs, supporting Healthy Aging by maintaining functional ability. Future research should focus on user-centered development of optimized exoskeleton designs for outdoor use, developing tailored rehabilitation programs, and educating healthcare professionals and caregivers to maximize benefits. This integrated approach holds potential to significantly improve life-space mobility and quality of life for the aging population.

Individual and environmental variables related to outdoor walking among older adults: Verifying a model to guide the design of interventions targeting outdoor walking

OBJECTIVE

To estimate the relationships between individual and environmental variables and outdoor walking (OW) in older adults with OW limitations through verifying a conceptual model.

METHODS

Baseline data from 205 older adults participating in a randomized trial of a park-based OW program were analyzed using structural equation modeling. We evaluated a three latent factor model: OW (accelerometry and self-report); individual factors (balance; leg strength; walking self-confidence, speed and endurance; mental health; education; income; car access); and environmental factors (neighbourhood walkability components).

RESULTS

Mean age was 75 years; 73% were women. Individual factors was significantly associated with OW (β = 0.39, p < .01). Environmental factors was not directly associated with OW but was indirectly linked to OW through its significant covariance with the individual factors (β = 0.22, p < .01). The standardized factor loadings from the individual factors on walking self-confidence and walking capacity measures exceeded 0.65.

CONCLUSIONS

Better walking capacity and more confidence in the ability to walk outdoors are associated with higher OW in older adults. Better neighbourhood walkability is indirectly associated with more OW. The conceptual model demonstrates an individual and environment association; if the capacity of the individual is increased (potentially through walking interventions), they may be able to better navigate environmental challenges.

Urinary incontinence and life-space activity/mobility additively increase the risk of incident disability among older adults

OBJECTIVES

To examine the associations of a combination of urinary incontinence (UI) and life-space activity/mobility with the risk of incident disability among community-dwelling older adults.

STUDY DESIGN

The participants were 12,808 older adults for the cross-sectional study and 12,516 older adults who completed the follow-up assessment.

MAIN OUTCOME MEASURES

UI was assessed using a questionnaire. Life-space activity/mobility was evaluated using total, physical, and social scores on the Active Mobility Index (AMI). Participants were classified into four groups (high AMI total score + no UI; high AMI total score + UI; low AMI total score + no UI; low AMI total score + UI). Incident disability was extracted from the Japanese Long-Term Care System.

RESULTS

During the 24-month follow-up, 562 participants (4.5 %) developed disability. Those with a low AMI score + no UI (hazard ratio, 1.35; 95 % confidence interval, 1.07-1.71) and those with a low AMI score + UI (hazard ratio, 2.00; 95 % confidence interval, 1.56-2.56) had a higher risk of incident disability than those with a high AMI score + no UI in the follow-up analysis.

CONCLUSIONS

A combination of UI and low AMI score was associated with an increased risk of incident disability, whereas having UI but a high AMI score was not associated with an increased risk of incident disability. Our findings may help identify older adults at high risk of developing disabilities.

Physical Activity in Community-Dwelling Older Adults: Which Real-World Accelerometry Measures Are Robust? A Systematic Review

Measurement of real-world physical activity (PA) data using accelerometry in older adults is informative and clinically relevant, but not without challenges. This review appraises the reliability and validity of accelerometry-based PA measures of older adults collected in real-world conditions. Eight electronic databases were systematically searched, with 13 manuscripts included. Intraclass correlation coefficient (ICC) for inter-rater reliability were: walking duration (0.94 to 0.95), lying duration (0.98 to 0.99), sitting duration (0.78 to 0.99) and standing duration (0.98 to 0.99). ICCs for relative reliability ranged from 0.24 to 0.82 for step counts and 0.48 to 0.86 for active calories. Absolute reliability ranged from 5864 to 10,832 steps and for active calories from 289 to 597 kcal. ICCs for responsiveness for step count were 0.02 to 0.41, and for active calories 0.07 to 0.93. Criterion validity for step count ranged from 0.83 to 0.98. Percentage of agreement for walking ranged from 63.6% to 94.5%; for lying 35.6% to 100%, sitting 79.2% to 100%, and standing 38.6% to 96.1%. Construct validity between step count and criteria for moderate-to-vigorous PA was rs = 0.68 and 0.72. Inter-rater reliability and criterion validity for walking, lying, sitting and standing duration are established. Criterion validity of step count is also established. Clinicians and researchers may use these measures with a limited degree of confidence. Further work is required to establish these properties and to extend the repertoire of PA measures beyond "volume" counts to include more nuanced outcomes such as intensity of movement and duration of postural transitions.

Older people's experience of the partial lockdown during the COVID-19 pandemic in Switzerland: a cross-sectional study

OBJECTIVES

This study aimed to evaluate older people's experience of a COVID-19 partial lockdown (16 March-11 May 2020) in Lausanne, Switzerland.

SETTING AND PARTICIPANTS

Community-dwelling participants of the Lausanne cohort (Lc65+) in 2020, aged 71-86 years (n=2642).

DESIGN AND OUTCOME

This cross-sectional study was nested within the Lc65+ longitudinal study. A specific COVID-19 questionnaire was sent on 17 April 2020 to evaluate participants' experience of the lockdown (outcome). Multinomial logistic regression models were used to determine the sociodemographic, living environment, health and social factors associated.

RESULTS

Out of 2642 participants, 67.8% described the lockdown as 'somewhat' difficult (reference group), 21.5% as 'not at all' difficult (positive) and 10.7% as 'very or extremely' difficult (negative). The relative risk of a positive experience was higher in participants living alone (relative risk ratio, RRR=1.93, 95% CI 1.52 to 2.46) or in a house (RRR=1.49, 1.03 to 2.16); lower in those who reported fear of falling (RRR=0.68, 0.54 to 0.86), functional difficulties (RRR=0.78, 0.61 to 0.99), feeling of loneliness (RRR=0.67, 0.49 to 0.91), unfamiliarity with communication technologies (RRR=0.69, 0.52 to 0.91), usual social support (RRR=0.71, 0.50 to 0.93), previous participation in group activities (RRR=0.74, 0.59 to 0.92) and among women (RRR=0.75, 0.59 to 0.95). The relative risk of a negative experience was higher in participants with fear of falling (RRR=1.52, 1.07 to 2.15), and lower in those who had a terrace/garden (RRR=0.66, 0.44 to 0.99) and owned a dog (RRR=0.32, 0.11 to 0.90).

CONCLUSIONS

Only one in 10 participants experienced the lockdown as very or extremely difficult. Specific interventions targeting vulnerability factors, such as fear of falling, could lessen the impact of any future similar situation.

Association between frequency of going out and mild cognitive impairment in community-dwelling older adults: a pilot study in frailty prevention groups

BACKGROUND

Clarifying the role of physical limitations in the relationship between frequency of going out and mild cognitive impairment (MCI) may be useful in supporting early detection and prevention of MCI. However, few studies have explored relatively active populations that are continuously active throughout the year. This study aimed to determine the relationship between frequency of going out and MCI among non-homebound older adults who participated in group activities to prevent frailty.

METHODS

This prospective cohort study used frequency of going out as the exposure and MCI as the outcome. The Touch Panel-type Dementia Assessment Scale and questionnaires about daily life were completed by 153 community-dwelling older adults aged ≥65 years participating in frailty prevention groups in a rural town. The baseline survey was conducted from December 2017 to March 2018 and analysed cross-sectionally. Follow-up surveys were conducted at 1- and 2-years and analysed longitudinally.

RESULTS

Univariate and binomial logistic regression analyses at baseline showed no association between MCI and frequency of going out in older adults with physical limitations. However, there was a significant association in older adults without physical limitations. A binomial logistic regression analysis of the frequency of going out at baseline and cognitive function at the 2-year follow-up showed no association between MCI and frequency of going out in older adults with physical limitations, but there was a significant association in those without physical limitations.

CONCLUSION

Our results suggest that frequency of going out may not be a useful indicator of MCI in older adults with physical limitations, although low frequency of going out may be an indicator of MCI in older adults without physical limitations.

Examining the factors associated with community ambulation in an older adult day hospital population

PURPOSE

The ability of an older adult to walk independently in their community assists with maintaining independence, a healthy lifestyle and a good quality of life. In clinical practice, outdoor mobility is often one of the first activities, where a decline is observed. The aim of this study was to examine the factors associated with community ambulation in community dwelling older adults attending a day hospital.

METHODS

This was a cross-sectional observational study design. Inclusion criteria were community dwelling older adults, over 65 years, attending a day hospital and able to ambulate at least 10 m with or without an assistive device. The primary outcome measure was a community ambulation questionnaire. A range of other outcome measures were completed assessing motor, cognitive, executive function and behavioural domains. Multivariate logistic regression was employed to identify independent predictors of community ambulation.

RESULTS

161 participants completed this study. The median age was 83 years (IQR 9), 64% were female and 49.1% lived alone. 55.3% of participants were classified as independent community ambulators. Mean gait speed was 0.8 m/s, median TUG score was 16.6 s and median frailty was 4 (IRQ 2) using the Clinical Frail Scale. Self-efficacy (p < 0.001) and gait speed (p = 0.030) were independently associated with community ambulation.

CONCLUSIONS

The findings demonstrate the complexity and multifactorial nature of community ambulation in older adults. This suggests the need to adopt a broader approach to the management of older adults, to promote the achievement of independent community ambulation.

Association between Frequency of Going Out and Psychological Condition among Community-Dwelling Older Adults after the COVID-19 Pandemic in Japan

Background: The psychological condition and frequency of going out (FGO) of community-dwelling older adults after the spread of COVID-19 will provide insights for supporting the daily lives of community-dwelling older adults. Going out is defined as moving from one’s own home to a place or region beyond one’s own home and is considered to reflect the daily and social life of community-dwelling older adults. This study investigates the relationship between the FGO and current psychological condition after the second wave of COVID-19 in community-dwelling older adults in Japan. Methods: This study adopted a self-administered questionnaire by mail. A total of 493 members of CO-OP Kagoshima were included in the analysis and divided into two groups according to the change in FGO. Multiple logistic regression analysis was conducted after a bivariate analysis to investigate the relationship between the FGO and psychological condition. Results: Significant differences were noted between the groups with decreased FGO and those with increased/unchanged FGO in general and pandemic-related psychological condition. Multiple logistic regression analysis showed a significant relationship between FGO and psychological condition, such as mental fatigue, not smiling as much as before, and anxiousness to go outside. Conclusion: Community-dwelling older adults may have experienced a decrease in the frequency of going out and a detrimental effect on their psychological condition after the COVID-19 pandemic. This finding may inform strategies to identify priorities for psychological approaches altered by COVID-19 to prevent confinement and stress in older adults.

Increased anxiety about falls and walking ability among community-dwelling Japanese older adults during the COVID-19 pandemic

BACKGROUND

Understanding the physical and mental changes in community-dwelling elderly people is very important during the coronavirus disease 2019 (COVID-19) pandemic when considering preventive measures. The purpose of this study was to clarify the changes of physical function and anxiety for activities of daily living in community-dwelling older adults, focusing on locomotor function during the COVID-19 pandemic.

METHODS

The study participants were 127 older people who participated in successive surveys, in the summers of 2019 and again in 2020, after the state of emergency. The Locomo 25 questionnaire, Geriatric Depression Scale-15 (GDS-15) questionnaire, medical history, and number of people living together were self-reported. The Locomo 25 covers six aspects of physical pain, movement-related difficulty, usual care, daily activity, social activities, and anxiety.

RESULTS

The paired samples t-test revealed that Locomo 25 total scores in 2020 were significantly higher than those in 2019. The GDS-15 score showed no significant difference. The comparison of scores for each item of the Locomo 25 revealed significantly higher scores in 2020 on Q21 ('difficult to perform sports activity', P = 0.0021), Q22 ('restricted from meeting own friends', P < 0.001), Q23 ('restricted from joining social activities', P < 0.001), Q24 ('anxious about falling in own house', P = 0.0023), and Q25 ('anxious about being unable to walk in the future', P = 0.0016).

CONCLUSIONS

About 2 months after declaration of the first state of emergency due to the COVID-19 pandemic in Japan, social activity was severely restricted. Older adults showed almost no changes in body pain and locomotive disabilities, but increases in their anxieties about walking ability and falling were remarkable.

Validation of the German Life-Space Assessment (LSA-D): cross-sectional validation study in urban and rural community-dwelling older adults

OBJECTIVES

To develop a German version of the original University of Alabama at Birmingham Study of Aging Life-Space Assessment (LSA-D) for measurement of community mobility in older adults within the past 4 weeks and to evaluate its construct validity for urban and rural populations of older adults.

DESIGN

Cross-sectional validation study.

SETTING

Two study centres in urban and rural German outpatient hospital settings.

PARTICIPANTS

In total, N=83 community-dwelling older adults were recruited (n=40 from urban and n=43 from rural areas; mean age was 78.5 years (SD=5.4); 49.4% men).

PRIMARY AND SECONDARY OUTCOME MEASURES

The final version of the translated LSA-D was related to limitations in activities and instrumental activities of daily living (ADL/iADL) as primary outcome measure (primary hypothesis); and with sociodemographic factors, functional mobility, self-rated health, balance confidence and history of falls as secondary outcome measures to obtain construct validity. Further descriptive measurements of health included hand grip strength, screening of cognitive function, comorbidities and use of transportation. To assess construct validity, correlations between LSA-D and the primary and secondary outcome measures were examined for the total sample, and urban and rural subsamples using bivariate regression and multiple adjusted regression models. Descriptive analyses of LSA-D included different scoring methods for each region. All parameters were estimated using non-parametric bootstrapping procedure.

RESULTS

In the multiple adjusted model for the total sample, number of ADL/iADL limitations (β=-0.26; 95% CI=-0.42 to -0.08), Timed Up and Go Test (β=-0.37; 95% CI=-0.68 to -0.14), shared living arrangements (β=0.22; 95% CI=0.01 to 0.44) and history of falls in the past 6 months (β=-0.22; 95% CI=-0.41 to -0.05) showed significant associations with the LSA-D composite score, while living in urban area (β=-0.19; 95% CI=-0.42 to 0.03) and male gender (β=0.15; 95% CI=-0.04 to 0.35) were not significant.

CONCLUSION

The LSA-D is a valid tool for measuring life-space mobility in German community-dwelling older adults within the past 4 weeks in ambulant urban and rural settings.
