OBJECTIVE: Food insecurity has been associated with mobility difficulty (MD) in old age. However, there is a scarcity of research on this topic from low- and middle-income countries, while the bio-psychological factors underlying this association are largely unknown. We investigated the food insecurity-MD link in Ghana and explored how sleep, anxiety, loneliness, and physical activity (PA) mediate the association.
METHODS: Community-based, representative cross-sectional data from the Aging, Health, Well-being, and Health-seeking Behavior Study were analyzed (N = 1201; Mage = 66.5; women = 63%). MD was assessed with items from the SF-36 of the Medical Outcomes Study. We assessed food insecurity with items on hunger and breakfast-skipping frequency due to lack of food and resources. Adjusted OLS and mediation models via bootstrapping technique evaluated the associations.
RESULTS: Results revealed the expected association between food insecurity and MD, such that greater food insecurity was significantly and positively associated with MD across paths (from β = 0.33 to β = 0.42, p < .001). Analyses of indirect effects showed that sleep problems (27.8%), anxiety (15.5%), loneliness (17.5%), and PA (18.0%) mediated the association between food insecurity and MD. Cross-level interactions revealed that food insecurity significantly modified the link between each mediator and MD.
CONCLUSIONS: Our data provide novel evidence that bio-psychological mechanisms may underlie the food insecurity-MD link and should, therefore, be considered relevant targets for interventions to prevent/manage MD in later life.

BACKGROUND: Spinal cord injury (SCI) is a devastating condition that often leads to significant impairments in physical function, leading to disability and mental health disorders. Hence, understanding the prevalence of SCI and the relationship between physical activity and mental health in individuals with SCI is crucial for informing rehabilitation strategies and optimizing outcomes.
OBJECTIVE: This study aims to comprehensively analyze existing research on the link between physical activity and mental health and identify the level of physical activity and mental health status, the barriers to physical activity, and SCI\'s impacts on psychological well-being in individuals with SCI.
METHODS: An electronic search strategy will be used to identify prevalence studies published since 1993 in health-related databases such as PubMed, MEDLINE, COCHRANE Library, and Wiley Library using the following query: \"Spinal Cord Injury\" OR \"Paraplegia\" OR \"Tetraplegia\" AND \"Physical Activity\" OR \"Exercise\" AND \"Mental Health\" OR \"Mental Illness\" OR \"Mental Disorder.\" Bibliographies of primary studies and review articles meeting the inclusion criteria will be searched manually to identify further eligible studies. The risk of bias in the included studies will be appraised using the Joanna Briggs Institute checklist for prevalence studies by 2 review authors. Any disagreement will be resolved by reaching a consensus.
RESULTS: Funding was received in October 2023, data collection will commence in July 2024, and the results are expected by 2025. We will summarize the selection of the eligible studies using a flowchart. The data from the studies will be extracted and tabulated. This scoping review will be published in a peer-reviewed journal in accordance with PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines.
CONCLUSIONS: This scoping review underscores the complex relationship between physical activity and mental health among individuals with SCI, highlighting the level of physical activity and mental health status, barriers to physical activity engagement, and psychological implications. Understanding these dynamics is crucial in devising tailored interventions aimed at enhancing mental well-being. This synthesis of evidence emphasizes the need for personalized strategies to promote physical activity, addressing unique challenges faced by this population to foster improved mental health outcomes and overall quality of life.

BACKGROUND: The long-term increase in life expectancy raises the question of whether the increased life expectancy is accompanied by an extension of years without health limitations. The study analyzes how life expectancy without functional and mobility limitations from the ages of 46 and 65 and their proportions of remaining life expectancy have changed since 2008.
METHODS: We analyze data from the German Ageing Survey of the 2008, 2014, and 2020/21 waves. Life expectancy without functional limitations (disability-free life expectancy-DFLE) was calculated using the Sullivan method. Severe functional limitations (using the Global Activity Limitation Indicator-GALI) and mobility limitations (climbing stairs, walking more than 1 km) were examined.
RESULTS: Compression of morbidity in the GALI has been observed in 46- and 65-year-old men since 2014, but not in women of the same age. In terms of mobility, 46- and 65-year-old men show trends towards compression when climbing stairs and 46-year-old men when walking more than 1 km since 2014. The values for women have stagnated for the first two indicators mentioned, but not for 46-year-old women since 2014 when walking more than 1 km.
CONCLUSIONS: Our analyses show different trends in DFLE depending on the indicator, age, and gender and do not allow a clear answer to the question of morbidity compression or expansion. We tend to see morbidity compression in men, whereas trends of stagnation or expansion tend to be seen in women. These results signal challenges in maintaining functional health, especially in women, and point to the need for targeted interventions to improve quality of life and healthy life expectancy.
UNASSIGNED: EINLEITUNG: Der langfristige Anstieg der Lebenserwartung wirft die Frage auf, ob die gewonnene Lebenszeit mit einer Verlängerung der Jahre ohne gesundheitliche Einschränkungen einhergeht. Die Studie untersucht, wie sich die Lebenserwartung ohne funktionelle und Mobilitätseinschränkungen ab dem Alter 46 und 65 Jahre sowie ihre Anteile an der Restlebenserwartung seit 2008 verändert haben.
METHODS: Wir analysieren Daten des Deutschen Alterssurveys der Wellen 2008, 2014 und 2020/2021. Die Lebenserwartung ohne funktionelle Einschränkungen (Disability Free Life Expectancy – DFLE) wurde mit der Sullivan-Methode berechnet. Untersucht wurden starke funktionelle Einschränkungen mit dem „Global Activity Limitation Indicator“ (GALI) und Einschränkungen der Mobilität (Treppensteigen, mehr als 1 km Gehen).
UNASSIGNED: Kompression der Morbidität beim GALI ist bei 46- und 65-jährigen Männern seit 2014 zu beobachten, bei gleichaltrigen Frauen dagegen nicht. Bei der Mobilität zeigen 46- und 65-jährige Männer Tendenzen zur Kompression beim Treppensteigen und 46-jährige Männer beim Gehen von mehr als 1 km seit 2014. Die Werte für Frauen stagnieren für die beiden erstgenannten Indikatoren, aber nicht für 46-jährige Frauen beim Gehen von mehr als 1 km seit 2014.
CONCLUSIONS: Unsere Analysen zeigen je nach Indikator, Alter und Geschlecht unterschiedliche Trends der DFLE und lassen keine eindeutige Antwort auf die Frage nach Morbiditätskompression oder -expansion zu. Kompression der Morbidität sehen wir eher bei Männern, Tendenzen der Stagnation oder Expansion dagegen eher bei Frauen. Diese Resultate signalisieren Herausforderungen in der Erhaltung der funktionellen Gesundheit vor allem bei Frauen und weisen auf die Notwendigkeit gezielter Interventionen hin, um die Lebensqualität und die gesunde Lebenserwartung zu verbessern.

UNASSIGNED: Older cancer survivors likely experience physical function limitations due to cancer and its treatments, leading to disability and early mortality. Existing studies have focused on factors associated with surgical complications and mortality risk rather than factors associated with the development of poor disability status (DS), a proxy measure of poor performance status, in cancer survivors. We aimed to identify factors associated with the development of poor DS among older survivors of colorectal cancer (CRC) and compare poor DS rates to an age-sex-matched, non-cancer cohort.
UNASSIGNED: This retrospective cohort study utilized administrative data from the Texas Cancer Registry Medicare-linked database. The study cohort consisted of 13,229 survivors of CRC diagnosed between 2005 and 2013 and an age-sex-matched, non-cancer cohort of 13,225 beneficiaries. The primary outcome was poor DS, determined by Davidoff\'s method, using predictors from 12 months of Medicare claims after cancer diagnosis. Multivariable Cox proportional hazards regression was used to identify risk factors associated with the development of poor DS.
UNASSIGNED: Among the survivors of CRC, 97% were 65 years or older. After a 9-year follow-up, 54% of survivors of CRC developed poor DS. Significant factors associated with future poor DS included: age at diagnosis (hazard ratio [HR] = 3.50 for >80 years old), female sex (HR = 1.50), race/ethnicity (HR = 1.34 for Hispanic and 1.21 for Black), stage at diagnosis (HR = 2.26 for distant metastasis), comorbidity index (HR = 2.18 for >1), and radiation therapy (HR = 1.21). Having cancer (HR = 1.07) was significantly associated with developing poor DS in the pooled cohorts; age and race/ethnicity were also significant factors.
UNASSIGNED: Our findings suggest that a CRC diagnosis is independently associated with a small increase in the risk of developing poor DS after accounting for other known factors. The study identified risk factors for developing poor DS in CRC survivors, including Hispanic and Black race/ethnicity, age, sex, histologic stage, and comorbidities. These findings underscore the importance of consistent physical function assessments, particularly among subsets of older survivors of CRC who are at higher risk of disability, to prevent developing poor DS.

BACKGROUND: Limited mobility in older adults consistently predicts both morbidity and mortality. As individuals age, the rates of mobility disability increase from 1.0% in people aged 15-24 to 20.6% in adults over 65 years of age. Physical activity can effectively improve mobility in older adults, yet many older adults do not engage in sufficient physical activity. Evidence shows that increasing physical activity by 50 min of moderate intensity physical activity in sedentary older adults with mobility limitations can improve mobility and reduce the incidence of mobility disability. To maximize the healthy life span of older adults, it is necessary to find effective and efficient interventions that can be delivered widely to prevent mobility limitations, increase physical activity participation, and improve quality of life in older adults. We propose a randomized controlled trial to assess the effect of a physical activity health coaching intervention on mobility in older adults with mobility limitations.
METHODS: This randomized controlled trial among 290 (145 per group) community-dwelling older adults with mobility limitations, aged 70-89 years old, will compare the effect of a physical activity health coaching intervention versus a general healthy aging education program on mobility, as assessed with the Short Physical Performance Battery. The physical activity health coaching intervention will be delivered by exercise individuals who are trained in Brief Action Planning. The coaches will use evidence-based behavior change techniques including goal-setting, action planning, self-monitoring, and feedback to improve participation in physical activity by a known dose of 50 min per week. There will be a total of 9 health coaching or education sessions delivered over 26 weeks with a subsequent 26-week follow-up period, wherein both groups will receive the same duration and frequency of study visits and activities.
CONCLUSIONS: The consequences of limited mobility pose a significant burden on the quality of life of older adults. Our trial is novel in that it investigates implementing a dose of physical activity that is known to improve mobility in older adults utilizing a health coaching intervention.

The life-history narratives of 10 Mexican American men with mobility limitations, age 55-77 years (mean = 63.8, SD = 5.8), were explored using a qualitatively driven, life-history mixed-methods study to understand perceptions of mobility limitations over the life course. Within that methodological and paradigmatic framework, conceptualizations of alterity and masculinity guided interpretation of data. Through an iterative, thematic analysis, we detail the way the men\'s lives were influenced by growing familial responsibility with age. Quantitative data were integrated into themes of narrative inheritance, family, and masculinity. It was posited that masculinity with mobility limitations shaped and was shaped by ethnic identity and responsibility. This has implications for understanding the experience of Mexican American men over the life course.

BACKGROUND: The association between motor capacity and the level of disability in patients with fibromyalgia remains underexplored. This study aims to explore the association between physical capacity tests explored in the consultation and the level of disability in women with fibromyalgia.
METHODS: There were 484 women diagnosed with fibromyalgia who were evaluated with 7 physical capacity tests: 10-m walk, 2-minute walk, 5-repetition getting up from a chair and sitting (G&S), 30-second chair stand, monopodal balance (right and left), and up-and-go. Functional performance was assessed with the Revised Fibromyalgia Impact Questionnaire (FIQR). Evaluation of the association between the physical capacity tests and the FIQR was initially performed using a principal component analysis (PCA). Subsequently, agglomerative hierarchical clustering (AHC) was performed in order to characterize groups of patients.
RESULTS: Results show than FIQR and the tests 10-m walk, 2-minute walk, 5-repetition G&S, 30-second chair stand, and up-and-go test were correlated. The results of the AHC determined 3 groups of patients mainly on one motor dimension with significant differences in both the FIQR and the physical capacity tests retained in the PCA (P < 0.001 for all).
CONCLUSIONS: The application of these physical tests is simple, fast and can be a complement to the FIQR questionnaire when determining the level of disability of patients with fibromyalgia, in addition to providing information on the evolution of the patients when these tests are administered in the clinical consultation.

Home modifications and features, e.g., handrails or ramps for people using wheelchairs, should allow residents with functional limitations to maintain social participation, health, and wellbeing for aging in place. However, there is little evidence in relation to the individual characteristics shaping this implementation of technology-based home modifications. Current studies often focus on describing the distribution of certain implementations in households but do not provide information on factors predicting the implementation or detailed and multifaceted data on associations with characteristics of the older user. This article, therefore, examines the use of well-established technological aids and home modifications (e.g., ramps, handrails, automatic doors, bathroom or kitchen modifications, chair lifts, and alerting devices) in the households of older adults in Europe. We refer to Lawton\'s and Nahemow\'s concept of personal-environment fit and describe the use of technical aids across 18 countries, analyze associations with individual characteristics and social resources, and compare those associations and variance explanation between older adults in their third age (\"young-old\", 65-79 years) and older adults in their fourth age (\"old-old\", 80+).
Drawing on representative data from the Survey of Health, Ageing, and Retirement in Europe (SHARE), wave 6, a total of N = 38,553 older adults aged 65-105 years (M = 74.4 years, SD = 7.1; 55% women) were analyzed by performing hierarchical logistic regression analyses.
Indicators of functioning explained the highest proportion of variance, followed by social resources, and variance explanation was higher for the fourth age than for the third age. In particular, older adults with physical limitations, a larger social network, and those who received care from a child outside the household were more likely to have home modifications installed.
The study provides an overview of associations of diverse variables with assistive devices and modifications in the home and can serve as a starting point for public health activities concerning the heterogeneity of people aged 65 years and older.

Many countries, including Sweden, are implementing policies aimed at delaying retirement and encouraging older workers to remain on the labour market for longer. During recent decades, there have been several major reforms to the pension and social security systems in Sweden. Moreover, the nature of occupations has shifted towards more non-manual and sedentary activities, older women are today almost as active in the labour market as men in Sweden, and physical functioning has improved over time. In this study, we investigate whether the importance of physical functioning as a predictor for retirement has changed over time, for women and men, respectively. We used four waves of nationally representative data from The Swedish Level of Living Survey from 1981, 1991, 2000, and 2010, together with income register data. We found that greater severity of musculoskeletal pain and mobility limitations increased the likelihood of retirement in all waves. Results from logistic regression models with average marginal effects and predictive margins showed that there is a trend towards physical functioning becoming less important for retirement towards the end of the study period, especially for women, when controlling for occupational-based social class, age, adverse physical working conditions, and job demands. People, especially women, reporting impaired physical functioning did not retire to the same extent as in previous decades. This indicates that people stayed longer in the labour market despite impaired physical functioning, which may have repercussions on well-being and quality of life.

This study identifies differences in unmet mobility needs among older adults living in rural versus urban areas.
We used data from Round 9 of the National Health and Aging Trends Study (NHATS), limiting our analyses to respondents who had not moved since baseline (average housing tenure of 27 years; n = 3343). We conducted bivariate and multivariate analyses to detect rural/urban differences in unmet mobility needs, adjusting for socio-demographics, health status, and housing characteristics.
Rural residence was associated with higher odds of any unmet mobility needs for older adults aging in place (adjusted odds ratio: 1.64, 95% confidence interval: 1.10-2.44, p < .05). The relationship between rurality and unmet needs for help with mobility limitations remained significant in fully adjusted models.
Rural older adults aging in place have greater unmet needs for help with mobility limitations. This study highlights several important gaps in supporting rural older adults aging in place.
