(1) Background/Objectives: The relationship between body mass index (BMI) and probable sarcopenia, a precursor to sarcopenia diagnosis, is unclear. While low BMI has been associated with sarcopenia risk, some evidence suggests that obesity may confer protection. We aimed to investigate the association between probable sarcopenia and BMI and, furthermore, to explore associations with waist circumference (WC). (2) Methods: This cross-sectional study included 5783 community-dwelling adults (mean age 70.4 ± 7.5 years) from Wave 6 of the English Longitudinal Study of Ageing (ELSA). Probable sarcopenia was defined using the European Working Group on Sarcopenia in Older People (EWGSOP2) criteria for low hand grip strength and/or slow chair rise. Associations between BMI and probable sarcopenia were examined using multivariable regression analysis and were similarly performed for WC. (3) Results: Our overall findings show that an underweight BMI was significantly associated with an increased likelihood of probable sarcopenia [OR (CI) 2.25 (1.17, 4.33), p = 0.015]. For higher BMI categories, the findings were conflicting. Overweight and obesity were associated with an increased likelihood of probable sarcopenia when defined by lower limb strength alone, [OR (CI), 2.32 (1.15, 4.70), p = 0.019; 1.23 (1.02, 1.49), p = 0.35, and 1.49 (1.21, 1.83), p < 0.001, respectively]. In contrast, overweight and obesity appeared protective when probable sarcopenia was assessed by low hand grip strength alone [OR (CI) 0.72 (0.60, 0.88), p = 0.001, and 0.64 (0.52, 0.79), p < 0.001, respectively]. WC was not significantly associated with probable sarcopenia on multivariable regression analysis. (4) Conclusion: This study supports the evidence that low BMI is associated with an increased likelihood of probable sarcopenia, highlighting an important at-risk group. The findings for overweight and obesity were inconsistent and may be measurement dependent. It seems prudent that all older adults at risk of probable sarcopenia, including those with overweight/obesity, are assessed to prevent underdetection of probable sarcopenia alone or with the double burden of obesity.

Sarcopenia is characterized by the accelerated loss of muscle strength, mass, and function in aging. The disease is a major public health issue with emerging evidence of a disproportionate burden in areas of socioeconomic disadvantage. To estimate the prevalence of probable sarcopenia overall, and according to Socioeconomic Position (SEP). To explore the association between markers of SEP and probable sarcopenia. Cross-sectional analysis of the English Longitudinal Study of Ageing data. England, United Kingdom (UK). This study comprised 6,052 older adult participants from Wave 6 of the English Longitudinal Study of Ageing (ELSA) aged 60 years and older. Probable sarcopenia was identified by the EWGSOP2 guidelines as low hand grip strength (females <16kg and males 15 seconds). Socioeconomic position was defined by educational attainment and subjective social status (SSS). Weighted multivariable regression analysis was employed to identify determinants of probable sarcopenia. Over one-third of older adults met the criteria for probable sarcopenia (33.7%; weighted, 36.1%) in the study population of mean age 70.7 (SD 7.7) years. When examined by SEP, the prevalence of probable sarcopenia was over 2-fold higher in adults in the most vs the least disadvantaged SEP groups (47.0% vs 20.6%, respectively, p<0.001). Multivariable regression analysis identified disadvantaged SEP, as measured by educational attainment and SSS, as independent predictors of probable sarcopenia, along with older age, physical inactivity, underweight BMI, chronic conditions, osteoarthritis, and minority group ethnicity. Disadvantaged SEP was associated with an increased likelihood of probable sarcopenia when controlled for other known risk factors. The findings suggest a need and opportunity for sarcopenia prevention and treatment strategies to address socioeconomic disadvantage in policies and practice.

Background: Adults of advanced age, with functional dependency, socioeconomic disadvantage, or a need for home care, are expected to be at high risk of sarcopenia, frailty and malnutrition, yet are likely to be underrepresented in research. We aimed to explore the assessment of sarcopenia, frailty, and malnutrition in-home, and to describe the practicality of performing these assessments. Methods: Home-based health assessments and post-study feedback surveys were conducted among community-dwelling older adults ≥65 years in receipt of state-funded home care (n = 31). Assessments included probable sarcopenia [hand-grip strength (HGS), chair rise-test, and SARC-F case-finding tool], the Mini Nutritional Assessment (MNA), and the Clinical Frailty Scale (CFS). Results: The study group was of mean age 83.2 ± 8.2 years, 74% were female and 23% lived in socioeconomically disadvantaged areas. Almost all met the criteria for probable sarcopenia (94%, n = 29/31), were frail or vulnerable by the CFS (97%, n = 30/31), and over a quarter were at risk of malnutrition (26%, n = 8). Participants had low physical activity (71.0%, n = 22/31), with a mean daytime average of 11.4 ± 1.6 h spent sitting. It was possible to assess probable sarcopenia (by HGS and SARC-F, but not the chair rise test), malnutrition (MNA), and frailty (CFS). Home-based research was a complex environment, and unearthed significant unmet need, prompting referrals to health services (36%, n = 11), in addition to technology assistance. The majority of participants (93%) reported a willingness to partake in future research. Conclusions: Most community-dwelling older people in receipt of home support, assessed in this exploratory study, were at risk of probable sarcopenia, frailty, and low physical activity, with over a quarter were at risk of malnutrition. Our initial findings provide practical data for large scale studies and may inform the development of intervention studies aiming to support ageing in place.

Purpose: Physical activity has been shown to improve older adults’ functional capacity, independence, and quality of life. In a feasibility study, we embedded a movement approach within older adults existing home care services through “Care to Move” (CTM). The aim of this qualitative study is to explore older adults’ experiences of CTM within their home care support services and to identify the strengths and barriers of engaging in CTM from the perspective of the older recipient. Materials and Methods: We conducted semi-structured telephone interviews with 13 older adults and one informal carer. Topics covered included participants’ overall experiences of CTM, changes to their overall activity and participation, aspects of CTM that they found valuable and issues that were challenging. Interview transcripts were coded and analyzed thematically to capture barriers and facilitators to the approach delivery. Results: Four themes were developed: i) “I have good days and bad days”, ii) “safety and security is the name of the game”, iii) “we’re a team as it stands’, iv) “it’s [COVID-19] depressing for everybody at the moment”. Older adults identified benefits of CTM engagement including improvements in physical and psychological wellbeing. However, subjective frailty and self-reported multimorbidity influenced overall engagement. Participants expressed concerns around the logistics of delivering CTM and competing care staff interests. The broader role of care staff in supporting CTM was highlighted, as well as the emotional support that staff provided to older adults. Care staff continuity was identified as a barrier to ongoing engagement. The impact of COVID-19 on older adults physical and mental health negatively impacted the delivery of the approach. Conclusion: Our findings suggest that embedding CTM within home care services is feasible and that older adults enjoyed engaging in CTM. Addressing care staff continuity and adopting individual approaches to CTM delivery may enhance the implementation of services.

Introduction: Socioeconomic disadvantage is associated with multiple adverse health outcomes in ageing. Whether this negative impact persists in populations of more advanced age and dependency is less clear. We aimed to determine the association between residential area deprivation and pre-specified health characteristics among community-dwelling dependent older adults. Methods: We conducted a cross-sectional analysis of data from 1591 community-dwelling adults aged 65 years and older of mean age 83.9 ± 7.1 years and in receipt of state home support in Ireland. The HP Pobal Deprivation Index was used to categorize residential areas by socioeconomic deprivation. Health variables analysed included physical dependency (Barthel Index), polypharmacy (≥ 5 medications), previous acute hospital admission, cognitive impairment, and mental health diagnoses. Associations between residential area deprivation and prespecified health outcomes were explored in multivariable logistic regression analysis. Results: In socioeconomically disadvantaged areas, high physical dependency was twice that observed in affluent areas (16.2% vs 6.9%, p = 0.009). Similarly, acute hospitalization, as the trigger for increased dependency, was more common in deprived settings (41.6% v 29.1%, p < 0.001). Polypharmacy was common in this population (67.6%), but significantly higher in deprived vs affluent settings (74.7% v 64.5%, p = 0.030). The findings persisted in multivariable analyses when adjusted for age and gender. While all participants were accessing home support, those in deprived areas were on average 6.5 years younger than in affluent areas. Associations between residential deprivation and mental health conditions or cognitive impairment, however, were not observed in this study. Conclusion: Community-dwelling older adults living in socioeconomically disadvantaged areas experienced greater polypharmacy, high physical dependency, hospitalization-associated dependency, and a 6.5-year earlier need for state home support than in affluent settings. The findings suggest that health inequality persists in populations of more advanced age and dependency and highlight a need for further research as well as community-based health and social care initiatives.

Introduction: In Ireland, over 55,000 older adults are supported in their community by formal home support, amounting to an estimated 23 million care hours annually. There is a growing need to move beyond care, to more proactive approaches to maintain physical function. In a feasibility study, we delivered the “Care to Move” (CTM) program through existing home support services. This qualitative study aimed to explore the experience and perceptions of Health Care Assistants (HCAs), who were trained in and delivered the CTM program. Methods: We conducted semi-structured telephone interviews with 22 HCAs [mean age 49.0 ± 10.7 years and female 21/22] involved in the delivery of the program with older adults [n = 35, mean age 82.8 (7.8) years]. Interview transcripts were coded and analyzed thematically to capture barriers and enablers to program delivery. Results: Barriers and enablers were identified under three themes i) the CTM approach ii) the home support setting, iii) older adults and physical activity, with iv) delivering care in a crisis and v) future directions further identified. Overall, there was a positive perception of the program’s focus on “movement prompts and motivators”, the “fit” within home support services, and the training provided. Practical challenges of limited time and the task-orientated nature of home support were reported as recurring barriers for CTM. Many HCAs commented on the value and perceived positive benefits of the program for their clients. Though negative perceptions of older adults’ motivation or ability to engage with physical activity were noted. Risk, such as injury or pain, was identified but was not a dominant theme. Conclusion: Our findings suggest that embedding physical activity initiatives within home support services could be feasible. Restructuring of services, engaging HCAs, and moving beyond traditional “task-oriented” care models to more personalised proactive approaches may facilitate this initiative and support aging in place.
