Multi-dimensional social frailty index for predicting disability and mortality in community-dwelling older adults: JAGES cohort.

The role of atenolol, a non-vasodilating beta-blocker drug, on long-term mortality in hypertensive older adults is still unclear. The aim of the present study was to evaluate long-term mortality in community-dwelling hypertensive older adults taking atenolol. Long-term mortality after 12-year follow up in isolated hypertensive older adults (n = 972) was analyzed. The patients were stratified in the presence and absence of atenolol use. Systolic, diastolic and pulse arterial pressure were measured. Older adults taking atenolol showed a greater mortality and higher pulse arterial pressure values than those not taking atenolol (73.9% vs 55.0%; P = 0.047 and 74.7 ± 14.1 vs 63.0 ± 14.2 mmHg, P < 0.001, respectively). Cox regression analysis showed that atenolol use (hazard risk 1.91; 95% confidence interval 1.04-4.31; P = 0.04) and pulse arterial pressure (hazard risk 1.02; 95% confidence interval 1.01-1.03; P = 0.032) were predictive of long-term mortality. Atenolol use was related to increased mortality in community-dwelling hypertensive Older adults. This increase in mortality risk seems to be related to an increase of pulse arterial pressure.

BackgroundPrevious studies suggest that frailty increases the risk of mortality, but the risk of cardiovascular disease (CVD) and all-cause mortality in Chinese community-dwelling older adults remains understudied. Our aim was to explore the effect of frailty on cardiovascular and all-cause mortality in older adults based on a large-scale prospective survey of community-dwelling older adults in China.MethodsWe utilized the 2014–2018 cohort of the Chinese Longitudinal Healthy Longevity Survey and constructed a frailty index (FI) to assess frailty status. Propensity score matching was used to equalize the baseline characteristics of participants to strengthen the reliability of the findings. Hazard ratios and 95% confidence intervals (CIs) were estimated using multivariate Cox models, adjusting for potential confounders, to assess the association between frailty and cardiovascular and all-cause mortality. The relationship between frailty and cardiovascular mortality was further explored using a competing risk model considering death as a competing event. The dose–response relationships between them were estimated using restricted cubic spline models.ResultsThe results of the multivariate Cox model found that the frailty group had a higher risk of CVD mortality (1.94, 95% CI: 1.43–2.63) and all-cause mortality (1.87, 95% CI: 1.63–2.14) in compared with the non-frailty group. The multivariate competing risks model suggested a higher risk of CVD mortality in the frailty group (1.94, 95% CI: 1.48–2.53). The analysis found no non-linear relationship between FI and the risk of CVD mortality but a non-linear dose–response relationship with the risk of all-cause mortality.ConclusionsFrail older adults demonstrated a stronger risk of CVD and all-cause mortality. Reversing frailty in older adults is therefore expected to reduce the risk of death in older adults.

Although the prevalence rates of hypertension (HTN) and diabetes mellitus are slowing in some high-income countries, HTN and diabetes mellitus remain as the two major risk factors for atherosclerotic cardiovascular disease (CVD), the leading cause of death in the United States and worldwide. We aimed to observe the association of HTN and diabetes mellitus with all-cause and CVD mortality in older white adults. All community-dwelling Rancho Bernardo Study participants who were at least 55 years old and had carefully measured blood pressure and plasma glucose from 75-g oral glucose tolerance test at the baseline visit (1984-1987, n = 2186) were followed up until death or the last clinic visit in 2013 (median 14.3 years, interquartile range 8.4-21.3). In unadjusted analyses, diabetes mellitus was associated with all-cause mortality [hazard ratio 1.40, 95% confidence interval (CI) 1.23-1.60] and CVD mortality (hazard ratio 1.67, 95% CI 1.39-2.00); HTN with all-cause mortality [hazard ratio 1.93 (1.73-2.15)] and CVD mortality [hazard ratio 2.45 (2.10-2.93)]. After adjustment for cardiovascular risk factors, including age, BMI, triglycerides, HDL-cholesterol, smoking, exercise, and alcohol consumption, diabetes mellitus was associated with CVD mortality only (hazard ratio 1.25, P = 0.0213). Conversely, HTN was associated with both all-cause (hazard ratio 1.34, P < 0.0001) and CVD mortality (hazard ratio 1.40, P = 0.0003). Having both diabetes mellitus and HTN was associated with all-cause (hazard ratio 1.38, P = 0.0002) and CVD mortality (hazard ratio 1.70, P < 0.0001). We report the novel finding that HTN is more strongly associated with all-cause and CVD mortality than diabetes mellitus. Having both confers a modest increase in the hazards for these types of mortality.

Interaction between handgrip strength and vitamin D deficiency on all-cause mortality in community-dwelling older adults: a prospective cohort study

Recent findings suggest that the distribution of protein intake throughout the day has an impact on various health outcomes in older adults, independently of the amount consumed. We evaluated the association between the distribution of dietary protein intake across meals and all-cause mortality in community-dwelling older adults. Data from 3225 older adults aged ≥ 60 years from the Seniors-ENRICA-1 cohort were examined. Habitual dietary protein consumption was collected in 2008-2010 and in 2012 through a validated diet history. Protein distribution across meals was calculated for each participant as the coefficient of variation (CV) of protein intake per meal, in sex-specific tertiles. Vital status was obtained from the National Death Index up to 30 January 2020. Cox proportional hazards regression was performed to determine the hazard ratios (HR) and their 95 % CI for the association between the distribution of daily protein intake across meals and all-cause mortality. Over a median follow-up of 10·6 years, 591 deaths occurred. After adjustment for potential confounders, the CV of total protein intake was not associated with all-cause mortality (HR and 95 % CI in the second and third tertile v. the lowest tertile: 0·94 (0·77, 1·15) and 0·88 (0·72, 1·08); Ptrend = 0·22). Similarly, the HR of all-cause mortality when comparing extreme tertiles of CV for types of protein were 0·89 (0·73, 1·10) for animal-protein intake and 1·02 (0·82, 1·25) for plant-protein intake. Dietary protein distribution across meals was not associated with all-cause mortality, regardless of protein source and amount, among older adults. Further studies should investigate whether this picture holds for specific causes of death.

Social Frailty Predicts Incident Disability and Mortality Among Community-Dwelling Japanese Older Adults

Plasma Neutrophil Gelatinase–Associated Lipocalin Is Independently Associated With Cardiovascular Disease and Mortality in Community-Dwelling Older Adults: The Rancho Bernardo Study

Background: Frailty is defined as a state with increased vulnerability in functioning across multiple physiological systems when facing stressors. Often three domains of frailty are considered: physical, psychological, and social. These three domains of frailty may relate to each other and develop over time. This study aimed to gain insight into the associations between physical, psychological and social frailty in order to support personalized prevention and care for older adults. Methods: Participants were 1781 older adults in the population-based Urban Health Centres Europe (UHCE) project. Repeated assessments of physical, psychological, and social frailty and covariates were collected at baseline and one-year follow-up. Linear regression analyses were conducted to examine the unidirectional associations. Cross-lagged panel modelling was used to assess bi-directional associations. Results: The mean age of participants in this study was 79.57 years (SD=5.54). More than half were female (61.0%) and completed secondary education (64.0%). A bi-directional association existed between physical and psychological frailty (effect of physical frailty at baseline on psychological frailty at follow-up: β=0.14, 95%CI:0.09, 0.19; reversed path: β=0.05, 95%CI:0.01, 0.09). A stronger effect from physical to psychological frailty was observed (Wald test for comparing lagged effects: P&lt;0.05). A unidirectional association indicated that a higher level of physical frailty was associated with a higher level of social frailty over one-year (β=0.05, 95%CI:0.01, 0.68). No associations were found between social and psychological frailty. Conclusion: This longitudinal study suggests that among community-dwelling older adults, a reciprocal relationship may exist between physical and psychological frailty, with a stronger effect from physical to psychological frailty. Also, a higher level of physical frailty was associated with a higher level of social frailty. Further research is needed to validate our findings and explore the underlying pathways. Meanwhile, public health professionals should be aware of the associations between physical, psychological and social frailty in order to provide personalized prevention and care.

BackgroundThe Short Physical Performance Battery (SPPB) is an instrument for assessing physical performance widely used in research among the elderly in multiple settings. We did not find Brazilian longitudinal studies that aimed to analyze the predictive capacity and accuracy of the SPPB among community-dwelling older adults and no systematic reviews were found on the accuracy of the SPPB in predicting mortality in community- dwelling older adults. This study aimed to analyze the capacity and accuracy of the SPPB for predicting mortality in community-dwelling older adults, as well as to determine cut-off points for men and women.MethodLongitudinal observational study conducted with 411 (70.1 ± 7.25 years) community-dwelling older adults, between 2017 and 2020 (37.7 ± 6.24 months). Physical performance was evaluated using the SPPB and information on the all-cause mortality rate was also recorded. Multivariate Cox regression analyses and curves were performed using the Kaplan–Meier method. Receiver Operating Characteristic (ROC) curves were constructed, with the parameters of area under the ROC curve (AUC) to determine cutoff points for discriminating mortality, considering a significance level of 5% (p < 0.05) and 95% confidence interval (CI) 95%.ResultsOlder adults with very low and low physical performance in the SPPB, showed higher risks of mortality (HR = 9.67; 95% CI [1.20–77.65]; HR = 4.06; 95% CI [1.09–15.01]), respectively. In the subtest’s analysis, older adults with low performance in the balance (HR = 0.54; 95% CI [0.36–0.81]) and gait speed tests (HR = 0.50; 95% CI [0.33–0.76]) showed greater risks of dying. The same was reproduced for categories in each test (participants that scored 2 points in the balance test had an HR = 5.86; 95% CI [1.84–18.61] and 2 points in the gait speed test, HR = 5.07; 95% CI [1.76–14.58]. The cutoff point ≤ 9 in the SPPB set the discriminator criterion for mortality in older people of both sexes.ConclusionsThe SPPB, as well as the balance and gait speed subtests were predictors of mortality, and the SPPB is accurate in predicting mortality among community-dwelling older adults.

BackgroundThe relationship between serum cholesterol and mortality remains disputed. This study aimed to examine the association of low and high-density lipoprotein cholesterol (LDL-C and HDL-C) with all-cause mortality among community-dwelling older adults in the Shanghai Aging Study.MethodsWe followed 3,239 participants free of lipid-lowering agents for a median of 10 years. Levels of LDL-C and HDL-C were measured at baseline using fasting blood samples. Survival status was confirmed by the local mortality surveillance system. The associations between the levels of LDL-C, HDL-C, and all-cause mortality were assessed by Cox proportional hazards models.ResultsThe increment of LDL-C concentration was related to a lower risk of mortality (p for trend < 0.05). Using the highest quintile of LDL-C (≥4.10 mmol/L) as a reference, the lowest quintile of LDL-C (<2.61 mmol/L) was associated with the highest risk of mortality, after adjusting for confounders (HR 1.67; 95% CI 1.26–2.21), exclusion of death within the first 2 years of follow-up (HR 1.57; 95% CI 1.17–2.11), and exclusion of functionally impaired participants (HR 1.46; 95% CI 1.07–2.00). A U-shape relationship was found between HDL-C level and the mortality risk. Using the third quintile of HDL-C (1.21–1.39 mmol/L) as a reference, HR (95% CI) was 1.46 (1.09–1.95) for the lowest quintile (<1.09 mmol/L) and 1.45 (1.07–1.96) for the highest quintile (≥1.61 mmol/L) of HDL-C, after adjusting for confounders; and 1.57 (1.15–2.15) for the lowest quintile and 1.45 (1.04–2.01) for the highest quintile of HDL-C, after exclusion of death within the first 2 years of follow-up; and 1.55 (1.11–2.16) for the lowest quintile and 1.42 (1.00–2.02) for the highest quintile of HDL-C, after exclusion of functionally impaired participants.ConclusionsWe found an inverse association of LDL-C and a U-shape relationship of HDL-C with long-term all-cause mortality in a cohort with community-dwelling older Chinese adults. Levels of LDL-C and HDL-C are suggested to be managed properly in late life.

With the aging of the population, frailty has attracted much attention, and the social dimension of frailty, namely social frailty, has also attracted attention. Studies have shown that social frailty can bring some adverse effects to the elderly, such as physical and cognitive function. To explore the risk of adverse health outcomes in older adults with social frailty compared with older adults with non-social frailty. Five databases were systematically searched from inception to February 28, 2023. Screening, data extraction and quality assessment were conducted independently by two researchers. The included studies were longitudinal studies of adverse outcomes in community-dwelling socially frail older adults, and the quality of each study was assessed using the Newcastle‒Ottawa Scale. A total of 15 studies were included based on the inclusion criteria, of which 4 were subjected to meta-analysis. The mean age of the included population ranged from 66.3 to 86.5years. According to existing research, social frailty was predictive of some adverse outcomes, such as incident disability, depressive symptoms, and reduced neuropsychological function. The meta-analysis showed that social frailty had a significant predictive effect on mortality among older adults [HR = 2.27, (95% CI = 1.03-5.00)]. In community-dwelling older adults, social frailty was a predictor of mortality, incident disability, depressive symptoms and other adverse outcomes. Social frailty had a negative impact on older adults, so it was necessary to strengthen the screening of social frailty to reduce the incidence of adverse outcomes.

Impact of Atrial Fibrillation and Heart Failure, Independent of Each Other and in Combination, on Mortality in Community-Dwelling Older Adults

Association of muscle mass, muscle quality, and function with mortality in community-dwelling older adults: Focus on segmental phase angle and extracellular to intracellular water ratio.

BackgroundSarcopenia is an age-related syndrome characterized by progressive loss of muscle mass and function. While it is considered a key predictor of adverse health outcomes, comprehensive evidence regarding its long-term impact on functional decline and mortality in community-dwelling older adults remains limited.ObjectiveTo evaluate the longitudinal association between baseline sarcopenia and risks of functional decline and all-cause mortality among community-dwelling older adults, with subgroup analyses based on methods of sarcopenia assessment and domains of functional decline.MethodsWe conducted a systematic review and meta-analysis following PRISMA 2020 and MOOSE guidelines. Seven databases were searched from inception to September 30th, 2025. We included cohort studies of older adults aged 60 years and above, with sarcopenia defined by recognized criteria, and reporting effect estimates for functional decline or mortality with follow-up for 1 year or longer. A meta-analysis based on heterogeneity was conducted using either common or random-effects models.ResultsA total of 39 studies involving 76151 participants were included. Sarcopenia was significantly associated with an increased risk of all-cause mortality (29 publications, OR = 1.79, 95%CI: 1.55~2.06) and functional decline (16 publications, OR = 1.90, 95%CI: 1.55~2.32). Subgroup analyses revealed consistent associations across different muscle mass assessment methods (DXA, BIA, and CT). Notably, sarcopenia was associated with both physical (OR = 1.91, 95%CI: 1.52~2.40) and cognitive/psychological functional decline (OR = 2.03, 95%CI: 1.35~3.05). Heterogeneity was moderate to high but did not substantially alter the results in sensitivity analyses.ConclusionThis meta-analysis confirms that sarcopenia significantly predicts long-term functional decline and mortality in community-dwelling older adults, with robust associations across multiple muscle mass measurement methods and functional domains. These findings highlight the importance of standardized sarcopenia screening and early intervention to mitigate long-term functional impairment and mortality risk in aging populations.Clinical trial registrationPROSPERO (ID CRD42024595362).
