ObjectivesTo 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.DesignCross-sectional validation study.SettingTwo study centres in urban and rural German outpatient hospital settings.ParticipantsIn 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 measuresThe 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.ResultsIn 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.ConclusionThe 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.Trial registration numberDRKS00019023.

Objectives: To examine the association between perceived benefit from hearing aid (HA) use and life-space mobility among older adults. Method: Cross-sectional analysis of 76- to 91-year-old community-dwelling adults ( n = 702). Data on perceived hearing with and without a HA were obtained via postal questionnaire and data on life-space mobility (Life-Space Assessment, range = 0-120) via phone interview. Results: Participants who perceived more benefit from HA use, had a better life-space mobility score ( M = 65, SD = 2.6) than participants who had less benefit from using a HA ( M = 55, SD = 3.2). Participants who benefitted more from HA use did not differ from those who did not have a HA ( M = 63, SD = 0.9) in their life-space mobility score. Discussion: Perceived benefit from HA use is associated with higher life-space mobility among community-dwelling older adults. Future studies are needed to examine whether use of an appropriate HA promotes life-space mobility among those with difficulties in hearing.

ObjectivesTo examine the association of intrinsic capacity (IC) with life-space mobility (LSM) among community-dwelling older adults and to determine whether age and gender modify this relationship.DesignCross-sectional study.SettingPublic housing blocks, senior activity centres and community centres in the Northeastern region of Singapore.Participants751 community-dwelling older adults aged ≥55 years old and able to ambulate independently with or without walking aid.Primary and secondary outcome measuresIC and LSM. Standardised IC factor scores were calculated through confirmatory factor analysis using variables representing the five IC domains cognition, locomotion, sensory, vitality and psychological. LSM was measured using the University of Alabama at Birmingham Study of Aging Life-Space Assessment instrument. Association of IC with LSM and its effect modification by age and gender were examined with regression analyses.ResultsThe participants had a mean age of 67.6 and mean LSM score of 88.6. IC showed a positive and significant association with LSM (β=6.33; 95% CI=4.94 to 7.72) and the effect remained significant even after controlling for potential confounders (β=4.76; 95% CI=3.22 to 6.29), with p<0.001 for both. Age and gender did not demonstrate significant modification on this relationship.ConclusionsOur findings support the empirical rigour of the International Classification of Functioning, Disability and Health framework, which suggests that IC influences the extent to which a person participates in the community. Our findings also provide guidance for healthcare providers who aim to enhance LSM and promote healthy ageing in older adults.

Abstract Intrinsic capacity (IC), defined as ‘the composite of all physical and mental capacities of an individual’, is of increasing interest in geriatrics as a potential multidimensional measure of health in older adults. According to the International Classification of Functioning, Disability and Health (ICF) framework, IC, through its interactions with environmental factors, determines a person’s participation in the community. However, there is lack of empirical evidence demonstrating this association. The primary aim of this study was to examine the association of IC with Life Space Area (LSA; a measure of participation) among community-dwelling older adults. The secondary aim was to determine whether age and gender modify this relationship. Cross sectional analysis was performed on data from the Individual Physical Proficiency Test for Seniors (IPPT-S) study conducted in the Northeastern region of Singapore. Standardized IC factor scores were calculated through confirmatory factor analysis using variables that represented the 5 IC domains. Association of IC with LSA and its effect modification by age and gender were examined with regression analyses. The study included 751 participants with mean age of 67.6 and mean LSA score of 88.6. IC showed a positive and significant association with LSA (B=6.33, P&lt;0.001) and the effect remained significant even after controlling for potential confounders (B=4.76, P&lt;0.001). Age and gender did not show significant modification on this relationship. Our findings support the empirical rigour of the ICF framework and provide guidance for healthcare providers who aim to enhance life space mobility and promote healthy aging in older adults.

Tracking Technology

Abstract Global positioning system (GPS) tracking technology is increasingly used in aging research to objectively measure the spatial and temporal aspects of mobility in older adults. The review aims to systematically synthesize the literature to identify GPS-driven mobility measures and potential determinants of mobility limitation for community-dwelling older adults. A systematic search of six electronic databases was conducted. A total of 4897 articles were found with 2578 left to review after deduplication. Twenty-five studies met inclusion criteria: 24 cross-sectional studies and one follow-up study that measured mobility changes over time. Various types of GPS devices were used, including smartphones, GPS watches, or portable data logging kits. The GPS tracking period ranged from 1 to 30 days. The daily device wear time varied from 10 to 24 hours. Commonly reported GPS-based mobility measures included time out of home, distance moved, the number of out-of-home trips or walking tracts, the number of visited places, life-space area, and walking speed. Twenty-one studies reported some aspects of demographic, physical, psychosocial, or environmental factors related to the levels of GPS-based mobility. GPS tracking technology can continuously record individuals’ activities and functional abilities within their life space. We found that there was heterogeneity in ways of applying GPS technology and defining and measuring mobility in community-dwelling older adults. Given the lack of consistency in GPS-based mobility assessment, a clear definition of mobility and standardization of GPS data collection and analysis are required for comparison across studies and better understanding determinants of mobility limitation in community-dwelling older adults.

This study examined the prevalence of cognitive impairment among older adults in central Vietnam and the roles of communication (with or without communication devices) in the association between cognitive impairment and hearing loss. This cross-sectional study was performed on 725 randomly selected community-dwelling older adults aged ≥60 years from Thua Thien Hue province, Vietnam. Participants attended a face-to-face survey. Sociodemographic characteristics, social interaction with or without communication devices, health status and cognitive function using the Mini-Mental State Examination were reported. Ordinal logistic regression analysis was performed to quantify the association between hearing loss and cognitive function by frequency of communication with and without devices. Mild and severe cognitive impairment had prevalence rates of 23.6% and 19.3%, respectively. Cognitive impairment was more prevalent among older adults with hearing-loss, vision loss and difficulties with instrumental activities of daily living (IADL). The association between hearing loss and cognitive impairment was not significant when older adults had frequent communication with others using devices. This study presented the relatively high prevalence of cognitive impairment in community-dwelling older adults in Vietnam. Frequent communication using devices attenuated the association between hearing loss and cognitive impairment.

Dairy products (DP) are part of a food group that may contribute to the prevention of physical frailty. We aimed to investigate DP exposure, including total DP, milk, fresh DP and cheese, and their cross-sectional and prospective associations with physical frailty in community-dwelling older adults. The cross-sectional analysis was carried out on 1490 participants from the Three-City Bordeaux cohort. The 10-year frailty risk was examined in 823 initially non-frail participants. A food frequency questionnaire was used to assess DP exposure. Physical frailty was defined as the presence of at least 3 out of 5 criteria of the frailty phenotype: weight loss, exhaustion, slowness, weakness, and low physical activity. Among others, diet quality and protein intake were considered as confounders. The baseline mean age of participants was 74.1 y and 61% were females. Frailty prevalence and incidence were 4.2% and 18.2%, respectively. No significant associations were observed between consumption of total DP or DP sub-types and frailty prevalence or incidence (OR = 1.40, 95%CI 0.65–3.01 and OR = 1.75, 95%CI 0.42–1.32, for a total DP consumption >4 times/d, respectively). Despite the absence of beneficial associations of higher DP consumption on frailty, older adults are encouraged to follow the national recommendations regarding DP.

Osteopenia/osteoporosis and sarcopenia are common geriatric diseases among older adults and harm activities of daily living (ADL) and quality of life (QOL). Osteosarcopenia is a unique syndrome that is a concomitant of both osteopenia/osteoporosis and sarcopenia. This review aimed to summarize the related factors and clinical outcomes of osteosarcopenia to facilitate understanding, evaluation, prevention, treatment, and further research on osteosarcopenia. We searched the literature to include meta-analyses, reviews, and clinical trials. The prevalence of osteosarcopenia among community-dwelling older adults is significantly higher in female (up to 64.3%) compared to male (8–11%). Osteosarcopenia is a risk factor for death, fractures, and falls based on longitudinal studies. However, the associations between osteosarcopenia and many other factors have been derived based on cross-sectional studies, so the causal relationship is not clear. Few studies of osteosarcopenia in hospitals have been conducted. Osteosarcopenia is a new concept and has not yet been fully researched its relationship to clinical outcomes. Longitudinal studies and high-quality interventional studies are warranted in the future.

Abstract Personality is associated with predictors of homebound status like frailty, incident falls, and depression. It has been rarely investigated whether personality predicts homebound status among older adults. Using the combining cross-sectional data of the Year 2013 and Year 2014 data from the National Health and Aging Trends Study (NHATS), this study examined the association between personality traits and homebound status in a sample of community-dwelling older adults aged 65 years and older (N=2,788). Homebound status (non-homebound, semi-homebound, and homebound) was determined by the frequency, difficulty, and help of outdoor mobility. Personality traits, including conscientiousness, agreeableness, openness, extraversion, and neuroticism were assessed using the 10-item Midlife Development Inventory on a rating scale from 1 (not at all) to 4 (a lot). Each personality trait was included as a predictor in an ordinal logistic regression model to examine its association with homebound status after adjusting demographic and health-related covariates. The sample was on average 79±7.53 years old, non-Hispanic White (72.0%), female (58.6%), living alone (35.4%) or with spouse/partner only (37.4%). Seventy-four percent, 18%, and 8% of participants were non-homebound, semi-homebound, and homebound, respectively. Homebound participants tended to be less-educated older females. The average scores of conscientiousness, agreeableness, openness, extraversion, and neuroticism were 3.19±0.75, 3.57±0.56, 2.81±0.83, 3.13±0.75, and 2.22±0.86, respectively. Among these five personality traits, high conscientiousness (OR=1.34, p&lt;0.001) and extraversion (OR=1.16, p=.03) were associated with a reduced likelihood of being homebound. These findings provided a basis for potential personality assessment to identify and protect individuals with high homebound risk.
