Abstract 4121348: Impairments in Left Atrioventricular Coupling Underpins Reductions in Skeletal Muscle Mass and Function in Ageing Older Adults

Background: Age-related cardiovascular disease (CVD) may manifest with changes in left ventricular (LV) systolic or left atrial (LA) dysfunction. Alterations in functional performance between the LV and LA chambers characterized by LA-LV coupling may be a sensitive marker representative of impairments in global cardiac performance, compared to either chamber alone. The increasing relevance of skeletal muscle function towards cardiac health in ageing, motivated our current work that investigated associations between skeletal muscle function and LA-LV coupling. Aim : Using advanced cardiac magnetic resonance (CMR) that characterizes cardiac volumetric parameters and strain functions, we determined the association between handgrip strength (HGS) and appendicular lean mass (ALM) with left atrioventricular coupling index (LACI). Methods: Community older adults without CVD underwent simultaneous assessment of HGS by hand dynamometer, height-square adjusted ALM by bio-impedance, and LA phasic function (namely reservoir, conduit, booster strain) as well as LA and LV volumetric parameters by CMR feature tracking. LACI is defined as the ratio of the ratio of LA to LV end-diastolic volumes. We performed linear regression and multivariable logistic regression to examine the relationship between HGS/ALM and LACI. Results: Among 251 study participants (mean age: 71 ± 9.1 years, female 44.7%), 149 (59%) had impaired LACI. HGS was linearly associated with LACI (β=-0.004, p=0.003) and LVEDV (β=1.62, p<0.0001), and ALM was linearly associated with LA volume (β=0.55, p=0.018) and LVEDV (β=3.45, p<0.0001) (Figure.1). Participants with impaired LACI (> 25%) had lower HGS (mean=22.8 ± 7.1 kg vs 26.1 ± 6.4 kg, p= 0.0002), lower ALM (16.4 ± 4.2 kg/m2 vs 17.7 ± 3.8 kg/m2, p=0.014), higher LA volume (36.8 ± 15.2 ml vs 22.0 ± 5.5 ml, p < 0.0001) and lower LV end-diastolic volume (101.0 ± 24.2 ml vs 111.9 ± 27.3 ml, p = 0.0011). The association between impaired LA-LV coupling and lower HGS (β=-0.0647, 95%CI -0.0255, -0.1040, p=0.001) and lower ALM (β=-0.0776, 95%CI -0.0107, -0.1444, p=0.011) persisted after adjusting for age. Conclusion: Reduced HGS and ALM among community-dwelling older adults was associated with impaired LA-LV coupling suggestive of underlying early-stage LA remodelling and impairments in left atrioventricular compliance. Detection of reduced HGS and ALM in community cohorts may prompt early identification of older adults at risk of dysfunctional cardiac aging.

Abstract 4135001: Right Ventricular Function and Right Ventricular-Pulmonary Arterial Adaptations in Aging Older Adults

Background: Compared to our understanding of left ventricular (LV) dysfunction in cardiac aging, there is far less depiction of right heart function, especially right ventricular (RV) remodelling in response to pulmonary arterial (PA) changes with aging. Given the importance of cardio-respiratory function in declining aerobic capacity with age, identifying sensitive metrics of RV function would complete our understanding of RV and RV-PA conduit adaptations in aging. Methods: Community older adults without cardiovascular disease underwent prospective cardiac magnetic resonance (CMR) imaging that measured RV volumes (RV end-diastolic volume, EDV; end-systolic volume, ESV), RV function (RV ejection fraction, RVEF; RV global longitudinal strain, GLS) and RV-PA coupling (end-systolic elastance to arterial elastance, computed as ratio of LV stroke volume, SV to RVESV). A RV-PA coupling threshold of >1.5 (based on prior literature) implies effective RV adaptation Aerobic capacity (VO 2 ) was calculated. Multivariable regression adjusted for significant covariates. Results: We studied 251 participants (54.5% female, 70.78±9.07 years) with normal LV and RV function (mean LVEF, 65.13±7.51 %, RVEF, 64.25±6.98 %). RV-PA threshold of <1.5 defined poorer RV structure and function with lower RVEF (56.6 ± 3.95 vs. 67.5 ± 5.25, p < 0.001), RVGLS (28.13± 4.55 vs. 32.8 ± 5.1, p = 0.0065) and higher RVEDV index (73.2 ± 15.15 vs. 63.34 ± 12.03, p < 0.001), compared to those with RVPA > 1.5. Predictors of better RVGLS were female sex (β=0.189, adj. p=0.019), independent of systolic and diastolic blood pressure while predictors of RVESV were female sex (β=-0.433, adj. p<0.00), age (β=-0.195, adj. p<0.001) and body mass index (β=0.264, adj. p<0.001). Overall, women had better RVEF and RVGLS but lower RVSV and VO 2 (30.1±4,5 vs 37.7±5.1, ml/kg/min) compared to men (all p<0.001) (Table 1). Lower VO 2 among women compared to men was accompanied by higher RV-PA (2.1±0.7 vs 1.8±0.7, p<0.001). Female sex (β=0.233, 95% CI [0.158, 0.506, adj. p<0.001) was independently associated with RV-PA coupling on multivariable analyses. Conclusions: Novel CMR-derived right heart parameters defined RV function and RV adaptations as depicted by RV-PA interactions in older adults. Superior RV functions and RV-PA coupling in women may represent hemodynamic adaptations in women, despite lower aerobic capacities.

Abstract 4134990: Body Fat Quantitation Predicts Progressive Cardiac Dysfunction with Age: Sex-Dependent Variations And Clinical Outcomes

Background: Among older adults whose body mass index (BMI) readings may be spuriously reduced due to loss of skeletal muscle, BMI alone may lack specificity for body fat quantitation. In addition, sex-based hormones differentially influence body fat composition between the sexes with aging. To evaluate the cardiometabolic effect of body fat on older adults, we hypothesize that sex would exert differential effects on baseline and progression of cardiac dysfunction in older adults. Methods: Community older adults without cardiovascular disease (CVD) underwent prospective transthoracic echocardiography with simultaneous body fat quantitation (body fat mass (BFM), percentage body fat (PBF), and waist-hip ratio (WHR) by bioimpedance, at baseline and five-year intervals. Mitral early diastolic inflow velocity to early diastolic annular tissue velocity (E/e') and early to late diastolic inflow velocity (E/A) ratios were recorded. Multivariable regression models were adjusted for significant clinical variables. Adverse clinical outcomes were defined as mortality or hospitalization during follow-up. Results: Baseline and interval annotation of 409 older adults (mean age 61±12.7 years, 52% females) demonstrated deteriorations in E/A ratios of -0.1 ± 0.3 and E/e' ratios of 1.8 ± 2.8, over a mean duration of 4.9 ± 0.4 years. Baseline BFM (β -0.01, p<0.001; β 0.023, p=0.352) and PBF (β -0.008, p=0.002; β -0.007, p=0.759) predicted interval changes in E/A but not E/e' respectively independent of covariates (Table 1). In sex-specific analyses, higher baseline PBF was associated with deteriorations in E/A (β 0.010, p=0.028) among women and E/e' among men (β -0.069, p=0.020). Increases in PBF over time were particularly associated with reductions in E/A among women (β -0.005, p=0.047) independent of higher baseline PBF, in addition to significant interactions between sex and PBF in predicting changes in E/A. (Figure 1). Higher baseline WHR predicted adverse clinical outcomes [w1] among women (HR 1.09, 95%CI 1.03-1.16, p=0.005). Conclusion: Baseline and longitudinal increases in fat quantity defined a trajectory of deteriorations in cardiac function among older adults, and prognosticated poorer future outcomes, particularly among women with central adiposity as represented by WHR. Refining CVD risk based upon quantitative sex-specific fat targets for older adults may be a strategy in the future.

Abstract 4122780: Muscle Quality Defines Sarcopenic Obesity in Older Adults In Association with Cardiac Function

Background: Obesity phenotypes are increasingly used to define cardiovascular diseases (CVD) risks. Age-related deteriorations in skeletal muscle function have ignited interest in the co-occurrence of sarcopenia and obesity in older adults. However, the traditional definition of sarcopenia (low appendicular skeletal mass [ASM] and handgrip strength [HGS]) may lead to underdiagnosis of sarcopenic obesity (SO) in overweight individuals (due to higher muscle mass). To address this enigma, we evaluated the use of muscle quality (MQ), as an alternative metric for SO, in association with cardiac function. Methods: Community older adults without CVD were prospectively annotated for skeletal mass, HGS and cardiac function via bioimpedance analysis, dynamometer, and simultaneous acquisition of echocardiography respectively. Sarcopenia was defined by low ASM and low HGS. Low MQ (HGS divided by upper body ASM) was defined by males<5.76kg/kg and females<5.475kg/kg. Aerobic capacity (VO2 max,ml/kg/min) was computed by a physical activity prediction model. Mitral early diastolic inflow velocity to early diastolic annular tissue velocity (E/e’) and early to late diastolic inflow velocity (E/A) ratios were recorded. Results: Overall, low MQ was prevalent (34.3%) in n=574 participants (59% females), but only 17.4% fulfilled sarcopenia diagnosis. Higher BMI correlated with higher ASM but lower MQ (Fig 1). Low MQ prevalence was higher in the obese compared to the non-obese (64.7% vs 30.2%, p<0.0001). Low MQ group was significantly older (69.0±10.4 vs 64.8±14.0 years, p<0.0001), had higher prevalence of dyslipidemia (49.2% vs 40.9% p=0.002) and hypertension (45.2% vs 39.3% p<0.0001) than the normal MQ group. The low MQ group had greater left ventricular mass (129±45 vs 114±44, grams, p<0.0001), left atrial volumes (37±14 vs 33±13, ml, p=0.001), and demonstrated a greater degree of diastolic dysfunction (lower E/A (0.89±0.28 vs 1.1±0.49, p<0.0001 and higher E/e’(8.63±2.42 vs 8.00±2.58, p=0.005), compared to the high MQ. VO2 max was lower in low MQ group (33±5.7 vs 36±6.7, p<0.0001). By regression, low MQ was associated with E/A (β=-0.119, adjusted p<0.0001) and VO2 max (β=-0.137, p<0.0001) (Table 1). Conclusion: Muscle quality is a useful metric of muscle function for sarcopenia in obese older adults. The associations between low MQ with diastolic dysfunction and reduced aerobic capacity corroborate the clinical impact of MQ as a defining metric of sarcopenia in obesity.

Abstract 4137620: Serum Acylcarnitines Predict Longitudinal Deteriorations in Cardiac Function and Adverse Outcomes in Older Adults

Background: Circulating acylcarnitines (ACs), biomarkers of mitochondrial β-oxidative function, are linked to cardiovascular diseases (CVD) yet the extent to which ACs relate to prospective cardiac aging remains uncertain. We investigate the longitudinal associations between ACs, cardiac function, and clinical outcomes. Methods: A population-based sample of community older adults without CVD underwent baseline serum metabolomic profiling and interval echocardiography at five years. Incident hospitalizations were prospectively tracked from 2014 to 2021. Multiple linear regression adjusted for significant clinical variables. Results: Of 202 participants (baseline 65±11.9 years, 49.3% women), we observed interval increases in risk factors (hypertension 39% vs 52.2% p<0.001; dyslipidemia 39% vs 50% p=0.034; diabetes 11.7% vs 18.8% p=0.035; smoking 13.2% vs 24.7% p=0.003; waist circumference 81±10.1 vs 86±9.9cm p<0.001) during follow-up (4.9±0.4 years). These changes paralleled E/e’ increases (8.9±2.6 vs 11.1±3.3 p<0.001) and E/A decreases (1.09±0.4 vs 1.0±0.4 p<0.001). Baseline C8:1 (β=0.182 p=0.011), C22:3 (β=0.148 p=0.047), C22:5 (β=0.210 p=0.003), C5:1 (β=-0.142 p=0.048), and C16-OH (β=-0.156 p=0.028) levels were associated with E/e’ change over time while C6 (β=0.163 adj. p=0.019), C8:1 (β=0.137 adj. p=0.047), C10:2 (β=0.153 adj. p=0.035), C14:3 (β=0.147 adj. p=0.031), and C16:1-OH/C14:1-DC (β=0.158 adj. p=0.022) were associated with E/A change. At follow-up, baseline C8:1 (β=0.178 adj. p=0.006) and C10:3 (β=0.145 adj. p=0.024) were associated with E/e’ while C4-DC/C6-OH (β=-0.004 adj. p=0.034) was associated with E/A. Baseline C22:2 predicted incident hospitalizations (HR=1.20 95%CI 1.03-1.39, adj. p=0.018). Conclusion: Circulating ACs independently predicted declining cardiac function and adverse outcomes over five years among older adults without CVD. The prognostic effect of ACs should be translated to strategies targeting mitochondrial health in cardiac aging prevention.

Circulating Galectin-3 distinguishes global aortic aging among older women

Abstract Background Traditional cardiovascular risk factors may underestimate age-associated cardiovascular risk, particularly in estimating discrepant risks between sexes. As a marker of adverse cardiovascular events, aortic stiffness may improve risk assessment, but the requirement for advanced imaging equipment restrict widespread translation of this paradigm. Conversely, circulating blood biomarkers may augment mechanistic understanding and distinguish sex-based differences in aortic stiffness. Purpose Hypothesizing that Galectin-3 (Gal-3) is associated with aortic aging among older adults, we examined sex-based differences between Gal-3 and global aortic stiffness as assessed by a novel cardiac magnetic resonance (CMR)-derived measurement of aortic global longitudinal strain (AOGLS). Methods Community older adults without cardiovascular disease underwent simultaneous CMR with serum Gal-3 quantification using chemiluminescent microparticle immunoassays. Poorer AOGLS was defined as values below the 75th percentile of AOGLS measurements. Multivariable regression models were used to assess the association of Gal-3 with AOGLS. Results Of 255 participants (mean age 70.8 ±9.1 years, LVEF 66.3 ±8.3%), 44.3% were women. Poorer AOGLS was characterized by higher Gal-3 (B coefficient = -0.101, 95%CI [-0.167, -0.034], p = 0.003), mean age (B = -0.126, 95%CI [-0.154, -0.098], p <0.001), male sex (B = -0.991, 95%CI [-0.409, -1.572], p = 0.001), history of hypertension (B = -0.777, 95%CI [-1.364, -0.189], p = 0.010), diabetes mellitus (B = -0.888, 95%CI [-1.617,-0.158], p = 0.017), smoking (B = -1.346, 95%CI [-2.15, -0.542], p=0.001), pulse rate (B = -0.032, 95%CI [-0.055, -0.01], p = 0.005), systolic BP (B = -0.014, 95%CI [-0.025, -0.004], p = 0.009), and diastolic BP (B = -0.033, 95%CI [-0.06, -0.006], p = 0.018) on univariable linear regressions; no associations were observed with urine albumin-to-creatinine ratio, serum NT-ProBNP, or hs-Troponin I. After multivariable adjustments for sex, age, significant cardiovascular risk factors (hypertension, diabetes, smoking), and pulse rate, the inverse relationship between Gal-3 and AOGLS (Figure 1) persisted (B = -0.071 95%CI [-0.135, -0.008], adj. p = 0.028, R2 = 0.217). The association between Gal-3 and AOGLS was more marked among women (Figure 2), compared to men. Among women, higher Gal-3 characterized women with poorer AOGLS (17.04 ±3.73 ng/mL vs 15.48 ±3.55 ng/mL p = 0.040) (B = -0.120, OR 0.887, 95% CI [0.787, 0.999], adj. p = 0.048), independent of age. Conclusions Galectin-3 was adversely associated with novel CMR-derived AOGLS. Among these older adults with age-associated observations in AOGLS, Gal-3 highlighted sex-based differences in AOGLS and differentiated women with poorer AOGLS from women with better AOGLS. Serum Gal-3 measurements may be useful for detecting adverse patterns of aortic aging, particularly as an early approach in community older adults.

Relationships between altitude and depressive symptoms among middle-aged and older adults in China: a longitudinal study from the China health and retirement longitudinal study.

Previous studies have consistently documented positive associations between depressive symptoms and altitude; however, a longitudinal study of these relationships among middle-aged and older adult community populations in China has not been previously reported. We screened 17,705 subjects who met the inclusion criteria from the China Health and Retirement Longitudinal Study database 2011. The altitude is the altitude at which the participants lived in our study area. We estimated the prospective associations between altitude and depressive symptoms among middle-aged and older adults. The 10-item Center for Epidemiological Studies Depression Scale short form was used to measure depressive symptoms. A total of 6,594 participants without depressive symptoms were recruited from the same cohort in 2011 and were followed up in 2018. Multivariate logistic regression was used to assess the associations between altitude and depressive symptoms among middle-aged and older adults. The prevalence of depressive symptoms was 27.3% in our study. The prevalence of depressive symptoms increased with increasing altitude, and the prevalence of depressive symptoms in women was greater than that in men. Multivariate logistic regression adjusted for all other relevant variables showed that sex, altitude, education level, professional status and marital status were associated with depressive symptoms. This finding provides evidence of the relationship between altitude and depressive symptoms among middle-aged and older adult community populations in China and shows that depressive symptoms are significantly positively correlated with altitude and other factors, including sex, education level, professional status, and marital status.

Identifying complex emotional and relational needs of service users in Later Life CMHTs within the Greater Manchester Mental Health NHS Foundation Trust

The Community Mental Health Transformation Agenda places a focus on supporting adults and older adults with severe and enduring mental health difficulties, including care for older adults with complex emotional and relational needs (CERN). Current research has paid little attention to CERN in later life. Studies suggest that older adults with CERN present differently to younger adults. This means services may not be identifying and meeting the needs of these individuals. The aim of this scoping exercise was to understand the prevalence of CERN in older adult community mental health services in Greater Manchester. Data was collected on 347 service users under the Care Programme Approach with later life community mental health teams in Greater Manchester. Data was gathered from the Trust electronic record system and interviews with care co-ordinators. Findings revealed that services users had high levels of complex need, including high levels of service use and high levels of risk, especially for self-neglect. Findings aligned with scoping exercises conducted in other Trusts and provided a better understanding of the needs of this population.

Prevalence of sarcopenic obesity among older adults in communities of China: A multicenter, cross-sectional study.

This study investigated the prevalence of sarcopenic obesity (SO) among older adults in Chinese communities and its association with chronic diseases. We conducted a post-hoc analysis of a 2014-2015 multicenter cross-sectional study involving adults aged ≥60 years from three representative cities in China. The Asian Working Group for Sarcopenia diagnostic criteria and Chinese local cutoffs were employed to define SO. Data on medical history, lifestyle, quality of life, and cognitive function were collected. The overall prevalence of SO was 3.58% in men and 2.88% in women among 2821 participants. There was a notable increase in prevalence with age, with rates reaching 6.58% for men and 4.40% for women aged 70-79 years. In the group aged ≥80 years, the prevalence rate increased significantly, reaching 13.16% for men and 18.18% for women. Those with SO had higher body mass index (25.29 ± 1.55 kg/m² vs 24.16 ± 2.48 kg/m²; P < 0.001) and triceps skinfold thickness (21.17 ± 5.93 mm vs 19.34 ± 6.87 mm; P < 0.05) than the normal group. The prevalence of cardiovascular disease (15.38% vs 6.59%; P < 0.01), hypertension (56.04% vs 38.93%; P < 0.01), and stroke (7.69% vs 2.25%; P < 0.01) was also significantly higher in the SO group. Logistic regression showed that those with SO were more likely to have cardiac disease (odds ratio [OR] = 2.20; P = 0.016) and stroke (OR = 2.61; P = 0.039). The prevalence of SO increases with age among the older adult population in China, notably after age 80 years. SO individuals were more likely to have cardiac disease and stroke. It is important to focus on early identification and management strategies.

Intergenerational Care and Subjective Well-being: A Study of the Particularities of Ageing Amongst the Indigenous Peoples of Chile

Abstract This empirical study explores intergenerational caregiving and subjective well-being amongst older adults in Indigenous communities in rural Chile. Facing substantial social and economic challenges, these communities depend heavily on cultural traditions and family support systems. Data were collected from 1,348 older adults, aged sixty and above, using surveys to assess caregiving practices, intergenerational support and subjective well-being, measured by the Personal Wellbeing Index and the Perceived Social Support Questionnaire. Findings reveal that caregiving is deeply rooted in cultural and historical contexts, with positive aspects such as increased satisfaction and social connectedness, and negative aspects including stress and social isolation. Women predominantly assume caregiving roles, maintaining cultural traditions and supporting family well-being. Notable differences in intergenerational support and subjective well-being were observed based on ethnic group and gender. The implications for social work practice are insightful. The study highlights the need for culturally sensitive social work policies and inclusive strategies that address the well-being of older adults in these communities. Social workers and policymakers must consider cultural nuances and the unique needs of Indigenous populations, taking into account cultural identity, economic conditions and acculturation to develop effective support programmes.

Analysis of the Current Situation and Influencing Factors of Psychological Well-Being of Elderly People in the Community

Objective: To investigate the current psychological well-being of older people in the community and analyze its influencing factors. Methods: A total of 265 community-dwelling older adults aged 60 and above in Baoding City, Hebei Province, were selected through convenience sampling from November 2023 to March 2024. They were surveyed using a general information questionnaire and a comprehensive well-being questionnaire, with results analyzed statistically using SPSS 27.0. Results: Six dimensions of the psychological well-being scale for community older adults were identified: life vitality (P50 = 4.83), health concern (P50 = 4.6), self-worth (P50 = 5.6), friendly relationships (P50 = 5.33), altruistic behavior (P50 = 5.2), personality growth (P50 = 4.67), and comprehensive well-being (P50 = 161). Multivariate regression analysis showed that social isolation (β = -0.021, P &lt; 0.001), type of work (β = -0.142, P &lt; 0.001), chronic disease history (β = 0.004, P &lt; 0.001), need for mobility aid (β = 0.192, P &lt; 0.001), and monthly income (β = 0.381, P &lt; 0.001) were factors influencing psychological well-being. Conclusion: The psychological well-being of the elderly is slightly above moderate and requires improvement. Enhancing factors such as reducing social isolation, addressing chronic disease history, and improving financial support could improve psychological well-being in older adults.

Effects of Virtual Reality Motor-Cognitive Training for Older People With Cognitive Frailty: Multicentered Randomized Controlled Trial.

Cognitive frailty refers to a clinical syndrome in which physical frailty and mild cognitive impairment coexist. Motor-cognitive training and virtual reality (VR) have been used to launch various therapeutic modalities to promote health in older people. The literature advocates that motor-cognitive training and VR are effective in promoting the cognitive and physical function of older people. However, the effects on older people with cognitive frailty are unclear. This study examined the effects of VR motor-cognitive training (VRMCT) on global cognitive function, physical frailty, walking speed, visual short-term memory, inhibition of cognitive interference, and executive function in older people with cognitive frailty. This study used a multicentered, assessor-blinded, 2-parallel-group randomized controlled trial design. Participants were recruited face-to-face in 8 older adult community centers. Eligible participants were aged ≥60 years, were community dwelling, lived with cognitive frailty, had no dementia, and were not mobility restricted. In the intervention group, participants received VRMCT led by interventionists with 16 one-hour training sessions delivered twice per week for 8 weeks. In the control group, participants received the usual care provided by the older adult community centers that the investigators did not interfere with. The primary outcome was global cognitive function. The secondary outcomes included physical frailty, walking speed, verbal short-term memory, inhibition of cognitive interference, and executive function. Data were collected at baseline (T0) and the week after the intervention (T1). Generalized estimating equations were used to examine the group, time, and interaction (time × group) effects on the outcomes. In total, 293 eligible participants enrolled in the study. The mean age of the participants was 74.5 (SD 6.8) years. Most participants were female (229/293, 78.2%), had completed primary education (152/293, 52.1%), were married (167/293, 57.2%), lived with friends (127/293, 43.3%), and had no VR experience (232/293, 79.5%). In the intervention group, 81.6% (119/146) of participants attended >80% (13/16, 81%) of the total number of sessions. A negligible number of participants experienced VR sickness symptoms (1/146, 0.7% to 5/146, 3%). VRMCT was effective in promoting global cognitive function (interaction effect: P=.03), marginally promoting executive function (interaction effect: P=.07), and reducing frailty (interaction effect: P=.03). The effects were not statistically significant on other outcomes. VRMCT is effective in promoting cognitive functions and reducing physical frailty and is well tolerated and accepted by older people with cognitive frailty, as evidenced by its high attendance rate and negligible VR sickness symptoms. Further studies should examine the efficacy of the intervention components (eg, VR vs non-VR or dual task vs single task) on health outcomes, the effect of using technology on intervention adherence, and the long-term effects of the intervention on older people with cognitive frailty at the level of daily living.

Effects of health education applying role play on decision making in acute myocardial infarction situation among older adults in community

Acute myocardial infarction is a silent killer for people worldwide, especially older adults who often experience atypical symptoms, causing late decision-making and a high mortality rate. The unrecognition of atypical symptoms, unconcerned about their risk, and not knowing how to deal with this critical situation are the barriers to a quick decision to visit the emergency department and delaying treatment, resulting in serious adverse outcomes. Therefore, specific and effective health education among older adults is needed. This double-blinded randomized controlled trial explored the effectiveness of health education by applying a role-play promoting decision-making ability program when expecting acute myocardial infarction occurrence among community-dwelling older adults. The participants were 96 community-dwelling older adults in central northeastern Thailand. We collected data between November 2021 and April 2022. The multi-stage sampling was applied to include participants. The intervention was the role-play promoting decision-making ability program and home visit. Outcomes were measured a week before attending and after finishing the intervention. T-tests, Mann–Whitney U test, Chi-square, and Wilcoxon Signed Rank test compared the outcomes between and within groups. Moreover, adjusted analysis was also demonstrated. Results revealed that participants who attended the program improved their knowledge, belief, and decision-making; only perceived susceptibility did not show improvement. Moreover, after demonstrating an adjusted analysis, the program participants had better knowledge about symptoms, perceived benefits, barriers, self-regulation, possible calling 1669, and first action. In conclusion, a role-play promoting decision-making ability program can promote knowledge, belief, and decision-making when expecting acute myocardial infarction occurrence among community-dwelling older adults. This study proved that role-play is one strategy to promote the program's effectiveness by inducing attention before giving older adults health information. Nurses and other healthcare professionals can implement this program as part of standard practice.Clinical Trial Registration Number: TCTR20210928004 on 28/09/2021.

Association between the perceived built environment and health behaviors in older adults: a cross-sectional study from Beijing, China

BackgroundUnder the background of the increasing trend of population aging, the health and quality of life of older adults have become the focus of social concern. As an important part of older adults’ daily life, the design and configuration of the built environment may positively or negatively affect older adults’ health behaviors. Therefore, this study aims to explore the relationship between older adults’ perceived built environments and health behaviors, which is the association between perceived built environments and older adults’ physical activity (PA) and social interactions. This is important for optimizing the community built environment and improving the quality of life of older adults.MethodsIn this study, a questionnaire was surveyed on 916 Chinese older adults aged 60 and above. The questionnaire was used to collect demographic information and social interaction from the participants, and the Physical Activity Neighborhood Environment Scale (PANES) and the Physical Activity Scale for the Elderly (PASE) were used to assess older adults’ subjective perceptions of the built environment in their neighborhoods and their levels of PA, respectively. In data analysis, ANOVA and chi-square tests were used to compare the significance of differences between groups, and multiple linear regression model were used to estimate the association between older adults’ perceived characteristics of the built environment and their PA and social interaction.ResultsAfter controlling for confounders such as gender, age, BMI, and education level, the multiple linear regression model showed that perceived destination accessibility, neighborhood infrastructure, aesthetic qualities, and neighborhood environment indices were significantly correlated with PA (β = 0.083 ~ 0.095, P < 0.05) and social interaction (β = 0.087 ~ 0.144, P < 0.05) among older adults. In addition, neighborhood safety (β = -0.084, P < 0.05), social environment (β = 0.091, P < 0.01), and street connectivity (β = 0.112, P < 0.001) were also strongly associated with older adults’ social interaction.ConclusionsDifferent perceived built environment attributes are correlated with the health behaviors of Chinese older adults to different degrees. This finding helps to guide community planning and construction, provides an empirical basis for improving health behaviors of older adults, and provides an important reference for building healthy communities for older adults and realizing comprehensive healthy development of older adults.Trial registrationThere was no trial registration for this study, but the study was approved by the Institutional Review Board of Tsinghua University (No. THU0120230196).

Reliability and Validity of Revised Apathy Evaluation Scale-Self in Community-Dwelling Older Adults

ABSTRACT Objectives The questionnaire Apathy Evaluation Scale-Self (AES-S) has been widely adopted globally, demonstrating high reliability and validity. However, direct translation of the AES into Chinese does not fit well into the Chinese cultural setting, so a structured and comprehensive revision is needed to obtain a high reliability and validity version of the scale. Methods In this study, 436 adults aged ≥ 60 years from two communities in Beijing were assessed using a modified AES-S. The methodology included item analysis, exploratory factor analysis, and confirmatory factor analysis. The scale’s validity was tested using the Temporal Experience of Pleasure Scale (TEPS) and Mini-Mental State Examination (MMSE). Reliability assessment included retest reliability, internal consistency reliability, and split-half reliability. Results The modified Apathy Evaluation Scale-Self-Assessment (AES-S-C) presented a first-order four-factor structure with higher reliability and validity than the original version within the Chinese older adult community. Conclusions The revised AES-S-C is more suitable for the Chinese older adults in community settings. Clinical implications This self-rated scale is suitable for screening apathy among older adults in community or nursing facilities, aiding in the identification of cognitive impairment and promoting mental health.

“Making for Others”: A Creative Inquiry Into Understanding Older Men’s Motivations for Making

The do-it-yourself (DIY) and maker cultures have expanded into older adult communities and shown to bring a strong agency and well-being outcomes. Looking into well-established spaces, where older adults have engaged in making over a longer period, can provide an insight into the sustained motivations and benefits of making for older adults. Men’s sheds represent a great opportunity in this regard, as they are open, community spaces where retired, older men engage in woodworking, metalworking and other craft-based activities. We involved nine men’s shed members in a creative inquiry where a “probe kit” consisting of recycled timber and wooden materials was provided. The participants were asked to create an artifact from the kit for someone other than themselves. We interviewed them once they completed their projects and qualitatively analyzed their design process. Our findings show that older men’s involvement in making is driven by the ethos of “making for others” and can be seen across three themes: (1) creative expressions; (2) memories and social connections; and (3) practical needs. We unpack these themes in the paper and discuss factors that can play an important role when engaging with older adults.

Digital Inclusion among Community Older Adults in the Republic of Korea: Measuring Digital Skills and Health Consequences.

Many older adults are increasingly embracing digital technology in the Republic of Korea. This study investigated the relationship between the digital skills of Korean older adults and their perceived health status and digital technology application for health promotion. This mixed-method study comprised a community survey of 434 older adults aged ≥65 in two cities in South Korea, followed by focus group interviews. Five types of digital skills, 'operational internet skills', 'information navigation skills', 'social skills', 'creative skills', and 'mobile skills', were measured using the LSE digital skill measurement instrument. Multivariable analysis identified the influence of digital skills on health-related outcomes. Among them, 'social skills' associated positively with self-rated health (β 0.37, 95%CI 0.08, 0.65). 'Information navigation skills' contributed positively to the use of digital technology and the internet for a healthy lifestyle in terms of improving eating habits (β 0.43, 95%CI 0.09, 0.77), accessing healthcare (β 0.53, 95%CI 0.21, 0.85), and accessing long-term care services (β 0.45, 95%CI 0.11, 0.79). Thematic analysis revealed that the study participants use Korean language-based resources such as Naver and Kakao Talk for social connection to promote a healthy lifestyle. This study concludes that encouraging initial and sustained use of the internet and enhancing digital skills among Korean older adults can promote active and healthy aging.

Significance of plasma p-tau217 in predicting long-term dementia risk in older community residents: Insights from machine learning approaches.

Whether plasma biomarkers play roles in predicting incident dementia among the general population is worth exploring. A total of 1857 baseline dementia-free older adults with follow-ups up to 13.5 years were included from a community-based cohort. The Recursive Feature Elimination (RFE) algorithm aided in feature selection from 90 candidate predictors to construct logistic regression, naive Bayes, bagged trees, and random forest models. Area under the curve (AUC) was used to assess the model performance for predicting incident dementia. During the follow-up of 12,716 person-years, 207 participants developed dementia. Four predictive models, incorporated plasma p-tau217, age, and scores of MMSE, STICK, and AVLT, exhibited AUCs ranging from 0.79 to 0.96 in testing datasets. These models maintained robustness across various subgroups and sensitivity analyses. Plasma p-tau217 outperforms most traditional variables and may be used to preliminarilyscreen older individuals at high risk of dementia. Plasma p-tau217 showed comparable importance with age and cognitive tests in predicting incident dementia among community older adults. Machine learning models combining plasma p-tau217, age, and cognitive tests exhibited excellent performance in predicting incident dementia. The training models demonstrated robustness in subgroup and sensitivity analysis.

Factors influencing older adult community fall prevention exercise implementation: a scoping review.

Exercise that challenges balance is the most effective fall prevention intervention in community-dwelling older adults. Identifying factors influencing implementation of community fall prevention exercise programs is a critical step in developing strategies to support program delivery. To identify implementation facilitators, barriers, and details reported in peer-reviewed publications on community fall prevention exercise for older adults. Scoping review. We searched multiple databases up to July 2023 for English-language publications that reported facilitators and/or barriers to implementing an evidence-based fall prevention exercise program in adults aged 50+ years living independently. At least two reviewers independently identified publications and extracted article, implementation, and exercise program characteristics and coded barriers and facilitators using the Consolidated Framework for Implementation Research (CFIR). We included 22 publications between 2001 and July 2023 that reported factors influencing implementation of 10 exercise programs. 293 factors were reported: 183 facilitators, 91 barriers, 6 described as both a facilitator and barrier, and 13 unspecified factors. Factors represented 33 CFIR constructs across all five CFIR domains: implementation inner setting (n = 95 factors); innovation (exercise program) characteristics (n = 84); individuals involved (n = 54); implementation process (n = 40) and outer setting (n = 20). Eight publications reported implementation strategies used; 6 reported using a conceptual framework; and 13 reported implementation outcomes. The high number of factors reflects the complexity of fall prevention exercise implementation. The low reporting of implementation strategies, frameworks and outcomes highlight the ongoing need for work to implement and sustain community fall prevention exercise programs.

A community-academic partnered approach to designing a Virtual Village to address the needs of older adults living with HIV

ABSTRACT Many older adults living with HIV face unique challenges, including comorbidities, loneliness, and isolation. This community-academic partnered study elicited viewpoints from older adults living with HIV about the characteristics of a digital environment (“Virtual Village”) to combat against loneliness and isolation. We utilized Choice-Based Conjoint Analyses to determine preferred attributes of a Virtual Village. We also conducted focus groups and interviews with older adults living with HIV and used an iterative, data-driven approach to systematically identify emergent themes. Participants (N = 82) were aged 50–82 years and racially/ethnically diverse. The majority were men (78%), gay (66%), and lived with HIV for ≥15 years (83%). Cost was the factor that most drove participants’ preference for joining a Virtual Village. Thematic concerns included lack of technological confidence, internet access, potential for harassment in digital environments, privacy, and preference for in-person interactions. Praises centered on convenience and making connections across geographic distances. Participants emphasized the need for purposive strategies to form a cohesive and supportive community for older adults living with HIV. A moderated environment was recommneded to create a safe, structured, and comfortable digital environment for older adults living with HIV. A Virtual Village should be viewed as a bridge to in-person interactions.
