Association between frailty and suicidal ideation in older adults: A cross-sectional study

OBJECTIVES

This study seeks to investigate the potential correlation between various levels of frailty and suicidal ideation (SI) in older adults from the USA.

METHODS

Our cross-sectional study extracted data on adults ≥60 years from the NHANES in 2005-2018. Frailty levels were assessed by computing the Frailty Index, classifying individuals into robust, prefrail, and frail categories. SI was evaluated utilizing Item #9 of PHQ-9. Logistic regression and restricted cubic splines were employed for analysis.

RESULTS

The analysis comprised 8564 participants, revealing that 3.3% reported experiencing SI. The association between frailty and SI in older adults was statistically significant in crude model (OR: 5.94, 95% CI: 3.46-11.27, P < 0.001). Upon adjusting for baseline characteristics, the association remained robust (AOR: 5.35, 95% CI: 3.09-10.19, P < 0.001). Model II did not substantially alter the association between frailty and SI after further adjustment for lifestyle factors (AOR: 5.23, 95% CI: 3.02-9.98, P < 0.001). In a sensitivity analysis controlling for depression, the association remained statistically significant (AOR:3.62, 95%CI: 1.76-8.75, P = 0.001). Furthermore, the associations between the Frailty Index and SI were pronounced in the restricted cubic spline (RCS) models (P overall < 0.001, P nonlinearity = 0.771).

CONCLUSION

Frailty appears to heighten vulnerability to suicidal ideation in older adults. Training healthcare professionals to identify and address mental health issues related to frailty is crucial. Through comprehensive intervention measures, we can better safeguard the mental well-being of older adults and reduce the risk of suicide.

Early Origins of Frailty: Do Later-Life Social Relationships Alter Trajectories of Decline?

Objectives: Social relationships are widely regarded as salubrious, but do they mediate the influence of childhood experiences on frailty in later life? Drawing from cumulative inequality theory, we assess the influence of childhood experiences and adult relationships on frailty trajectories. Methods: We analyzed data from the Health and Retirement Study to examine the influence of six domains of childhood experiences and social relationships on frailty trajectories over 8 years. Mediation analyses were completed with structural equation models. Results: Risky adolescent behavior, chronic disease, and impairments during childhood are associated directly with higher risk of initial frailty, but not over time. More social roles and higher social support mediate the relationship between childhood experiences and frailty, and the effect of more social roles continues over time. Discussion: This study provides compelling evidence that supportive social relationships mediate the risk and severity of frailty in later life associated with noxious childhood experiences.

A Biopsychosocial Model Predicting Myocardial Infarction

Myocardial infarction is one of the main causes of death, and cardiovascular risk factors (CVRFs) are always considered when studying it. However, although it is known that other social and psychological variables, and especially frailty, can increase the risk of infarction, their simultaneous effect has not been extensively studied. This study is based on data from the SHARE project (latest wave, Wave 8), with a representative sample of 46,498 participants aged 50 or older (M = 70.40, SD = 9.33), of whom 57.4% were females. Statistical analyses included a full structural equation model that predicts 27% of infarction occurrence and evidences the significant effect of well-being, depression, and social connectedness on frailty. Frailty, in turn, explains 15.5% of the variability of CVRFs. This work supports the need to study these physical, social, and mental health factors together to intervene on frailty and, in turn, improve cardiovascular outcomes.

Sex and age as predictors of health-related quality of life change in Phase II cardiac rehabilitation

AIMS

Cardiac rehabilitation (CR) not only improves cardiovascular outcomes, but also health-related quality of life (HRQOL). Unfortunately, CR is still underutilized, especially among women and older patients. Aim of this study was to highlight age- and sex-specific effects of inpatient CR on HRQOL.

METHODS AND RESULTS

From 2012 to 2018, 18 459 patients were prospectively assessed in six Swiss CR clinics. Of these, we retrospectively analysed a final sample of 8286 patients with a mean (standard deviation) age of 67.8 (11.3) in men and 72.2 (11.3) in women. HRQOL was measured at CR entry and discharge. In multivariable analyses, sex- and age-specific changes in HRQOL throughout CR were estimated, adjusting for baseline HRQOL and clinical characteristics. Participants of both sexes improved significantly (P < 0.001) in all domains of HRQOL during CR. Women reported significantly lower social (P < 0.001) and emotional (P < 0.001) HRQOL than men at CR entry. Female sex predicted greater improvement in social (F = 19.63, P < 0.001), emotional (F = 27.814, P < 0.001), and physical HRQOL (F = 20.473, P < 0.001). In a subgroup of n = 2632 elderly patients (>75 years), female sex predicted greater changes in emotional (F = 15.738, P < 0.001) and physical (F = 6.295, P = 0.012), but not in social HRQOL.

CONCLUSION

Women report poorer HRQOL at CR entry compared with men, but in turn particularly benefit from CR in this regard. Our results indicate that sex- and age-specific needs of patients should be considered.

How Neighborhood Structural and Individual Characteristics Affect Frailty Progression: Evidence from the China Health and Retirement Longitudinal Study

OBJECTIVES

(1) To characterize the average trajectories of frailty over time in Chinese community-dwelling older adults; (2) To assess the effects of neighborhood structural and individual characteristics on frailty progression.

DESIGN

A nationally representative prospective cohort study.

SETTING

Communities in 28 provinces, China.

PARTICIPANTS

6238 respondents aged 60 and above in 447 communities from four waves of the China Health and Retirement Longitudinal Study.

MEASUREMENTS

Frailty was measured using the 61-item Frailty Index (FI).

RESULTS

The trajectory of FI was nonlinear, with an average growth rate of 0.025 that significantly slows down at the rate of 0.002 per year. Older, male, and uninsured respondents showed faster rates of growth in FI over time than younger, female, and insured counterparts. Respondents living in neighborhoods with a higher percentage of the older population and rural villages showed slower rates of growth in FI over time.

CONCLUSION

Expanding health insurance coverage and keeping a high clustering of the elderly in neighborhoods may be the potential strategies for population-level frailty prevention and interventions.

Being Uncertain: Rural-Living Cardiac Patients' Experience of Seeking Health Care

Cardiovascular disease (CVD) is a leading cause of morbidity and mortality worldwide. Secondary prevention strategies reduce disease progression to heart failure. Rural cardiac patients typically have less access to health care resources to support them in managing secondary prevention, and services to improve quality of life tend to be lacking in rural settings. The study aim was to examine the process that rural cardiac patients go through to access health care and cardiac rehabilitation (CR) following myocardial infarction (MI). In-depth interviews with 11 post-MI participants using Straussian grounded theory were undertaken. Analysis revealed a linear process from hospital discharge to maintaining health. There were five elements: comfort with health information, relationship with health care providers, social support, taking ownership, and availability of/for CR. The core category was "being uncertain." Findings can be used to identify ways to improve access and address uncertainty stemming from a lack of perceived information and supports following discharge.

Social Support and Mortality in Community-Dwelling Chinese Older Adults: The Mediating Role of Frailty

Purpose

Population ageing is posing an unprecedented challenge globally, necessitating a better understanding of modifiable factors and underlying pathways that could contribute to health and longevity in older age. We thus aim to investigate how the modifiable social support (and its various sources) is related to mortality among older adults, as well as whether and to what extent geriatric frailty plays a role in mediating the relationship.

Methods

We included 11,934 community-dwelling adults (≥65) from four waves of the Chinese Longitudinal Healthy Longevity Survey (2008–2018). Frailty was constructed by 44 health deficits, following a validated frailty index scale. Social support was measured using a sum score of three dimensions (family support, social service and social security) with 22 items. The outcome was all-cause mortality. Multivariate logistic or linear regression models were employed when appropriate to assess the associations among social support, frailty and mortality. Mediation analysis was applied to examine the role of frailty underlying the pathway between social support and mortality risk.

Results

A higher sum score of social support at baseline reduced mortality risk during the 10-year follow-up period (AOR=0.947, 95% CI=0.917~0.977). Amongst three sources of social support, family support and social security availability showed significantly protective effect against mortality, while social service revealed only non-significant effect. A higher level in the overall social support (β=−0.066, 95% CI=−0.113~-0.020) or family support (β=−0.121, 95% CI=−0.202~-0.039) was also significantly associated with decreased frailty. Meanwhile, frailty partially mediated the relationship of mortality with the overall social support and family support, where the proportion of mediation equaled to 17.1% and 20.5%, respectively.

Conclusion

Social support could be associated with reduced risks for frailty and mortality, and such protective influences are especially manifested in its family support component among Chinese older adults. Frailty functions as potential mediator underlying the association of mortality with social support and family support. Our findings indicate the importance of social support as an integral part of geriatric care and underline the potential benefits of frailty assessment and intervention.

Perceived social support and the risk of cardiovascular disease and all-cause mortality in the Women's Health Initiative Observational Study

OBJECTIVE

Previous studies have shown social support to be inversely associated with cardiovascular disease (CVD) in men, whereas fewer studies have assessed the relationship in women. The purpose of this study was to evaluate the relationship between perceived social support and cardiovascular outcomes among postmenopausal women enrolled in the Women's Health Initiative Observational Study.

METHODS

We examined the relationships between perceived social support and (1) incident coronary heart disease (CHD), (2) total CVD, and (3) all-cause mortality. Participants were Women's Health Initiative Observational Study women, ages 50 to 79 years, enrolled between 1993 and 1998 and followed for up to 10.8 years. Social support was ascertained at baseline via nine questions measuring the following functional support components: emotional/informational, tangible, positive social interaction, and affectionate support.

RESULTS

Among women with prior CVD (n = 17,351) and no prior CVD (n = 73,421), unadjusted hazard ratios ranged from 0.83 to 0.93 per standard deviation increment of social support. Adjustment for potential confounders, such as smoking and physical activity levels, eliminated the statistical significance of the associations with CHD and CVD. However, for all-cause mortality and among women free of baseline CVD, the association was modest but remained statistically significant after this adjustment (hazard ratio = 0.95 [95% confidence interval, 0.91-0.98]). No statistically significant association was observed among women with a history of CVD.

CONCLUSIONS

After controlling for potential confounding variables, higher perceived social support is not associated with incident CHD or CVD. However, among women free of CVD at baseline, perceived social support is associated with a slightly lower risk of all-cause mortality.

Prevalence and determinants of frailty in the absence of disability among older population: a cross sectional study from rural communities in Nepal

Background

Longevity and frailty have significant implications for healthcare delivery. They increase demands for healthcare service and surge risk of hospitalization. Despite gaining global attention, determinants of frailty have remained unmeasured in the rural community settings in Nepal. This study aimed to address this gap by accessing the prevalence and determinants of frailty in the absence of disability among older population living in rural communities in eastern Nepal.

Methods

We conducted a cross-sectional analytical study of 794 older adults aged ≥60 living in the rural part of Sunsari and Morang district of eastern Nepal between January and April in 2018. Multi-stage cluster sampling was applied to recruit the study participants. Study measures included socio-demographics; Frail Non-disabled scale (FiND) measuring frailty, Barthel’s Index measuring basic activities of daily living and Geriatric depression scale. Determinants of frailty in the absence of disability were identified using generalized estimating equation (GEE).

Results

About 65% of the participants self-reported the presence of frailty in the absence of disability. In the adjusted models, those from underprivileged ethnic groups, lack of daily physical exercise, presence of depressive symptoms and those not getting enough social support from family were found to be significantly associated with frailty among older participants.

Conclusions

The prevalence of frailty in the absence of disability was high among rural community old population living in eastern Nepal. Our findings suggest that need of frailty awareness (both for clinicians and general public), so as to avoid negative consequences. To reduce the healthcare burden early screening frailty in primary care has potentials to prevent implications of frailty in Nepal.

Disablement in Context: Neighborhood Characteristics and Their Association With Frailty Onset Among Older Adults

OBJECTIVES

Frailty, an aggregate expression of risk resulting from age- or disease-associated physiologic accumulation, is responsible for large economic and societal costs. Little is known about how the context in which older adult's live may contribute to differences in frailty. This study clarifies the role of neighborhood structural characteristics and social processes for understanding declines in health status.

METHOD

Data from two waves of the National Social Life, Health and Aging Project were linked to tract-level information from the 2000 Census (n = 1,925). Frailty was measured with in-home assessments and self-report. Ordered logistic regressions were employed to estimate the role of tract-level structural and social process indicators at baseline on frailty at follow-up.

RESULTS

Living in a neighborhood characterized with a higher density of African Americans and with more residential instability was associated with higher odds of frailty. Adults in neighborhoods with increasing levels of physical disorder had higher odds of frailty (adjusted odds ratio [AOR]: 1.20, 95% confidence interval [CI]: 1.03, 1.39), while those exposed to more social cohesion had lower odds (AOR: 0.87, CI: 0.78, 0.97).

DISCUSSION

For older adults, both neighborhood structural and social process characteristics appear to be independently associated with frailty.

Psychosocial Correlates of Frailty Among HIV-Infected and HIV-Uninfected Adults

Frailty is a geriatric condition characterized by increased vulnerability to physical impairments and limitations that may lead to disabilities and mortality. Although studies in the general population suggest that psychosocial factors affect frailty, less is known about whether similar associations exist among people living with HIV (PLWH). The purpose of this study was to examine psychosocial correlates of frailty among PLWH and HIV-uninfected adults. Our sample included 127 adults (51% PLWH) participating in the Multi-Dimensional Successful Aging among HIV-Infected Adults study at the University of California San Diego (average age 51 years, 80% male, 53% White). Frailty was assessed via the Fried Frailty Index. Psychosocial variables significant in bivariate models were included in principal component analysis to generate factor variables summarizing psychosocial correlates. Multivariate logistic regression models were fit to examine the independent effects of factor variables and their interaction terms with HIV status. In bivariate models, frailty was associated with multiple psychosocial variables, for example, grit, optimism, personal mastery, social support, emotional support. Factor analysis revealed that psychosocial variables loaded on two factors-Positive Resources/Outlook and Support by Others. The multivariate model showed significant main effects of Support by Others and HIV status, and interactive effects HIV X Positive Resources/Outlook, such that Positive Resources/Outlook was negatively associated with frailty for PLWH but not for HIV-uninfected individuals. These analyses indicate that psychosocial factors may be associated with frailty among PLWH. Positive resources and outlook may play a role in frailty prevention. Future longitudinal studies are needed to establish causal links.

Frailty profile in Brazilian older adults: ELSI-Brazil

OBJECTIVE

To estimate the prevalence of frailty and to evaluate the associated factors in the non-institutionalized Brazilian population aged 50 years or older.

METHODS

The analyses were conducted in 8,556 participants of the baseline survey of the Longitudinal Study of Health of the Brazilian Elderly (ELSI-Brazil) conducted in 2015 and 2016. Frailty was defined based on five characteristics: weight loss, weakness, slowness, exhaustion and low level of physical activity. Participants with three or more characteristics were classified as frail. A Poisson regression model was used to examine the association between frailty and sociodemographic and health factors.

RESULTS

The prevalence of frailty was 9.0% (95%CI 8.0-10.1) among participants aged 50 years or over. Among the older adults aged 60 or over, the prevalence was 13.5% (95%CI 11.9-15.3) and 16.2% (95%CI 14.3-18.3) among those 65 aged years or over. Factors associated with higher prevalence of frailty were low schooling, residence without a partner, health conditions (poor self-rated health and two or more chronic diseases) and limitation to perform basic activities of daily living.

CONCLUSIONS

The prevalence of frailty among Brazilians aged 65 years or older is similar to their European counterparts. Poor health conditions, functional limitation and low schooling emerge as the factors most strongly associated with the frailty in this population.

An analysis of the types of recently published research in the field of cachexia

Introduction Cachexia is a common complication of many and varied chronic disease processes, yet it has received very little attention as an area of clinical research effort until recently. We sought to survey the contemporary literature on published research into cachexia to define where it is being published and the proportion of output classified into the main types of research output. Methods I searched the PubMed listings under the topic research term "cachexia" and related terms for articles published in the calendar years of 2015 and 2016, regardless of language. Searches were conducted and relevant papers extracted by two observers, and disagreements were resolved by consensus. Results There were 954 publications, 370 of which were review articles or commentaries, 254 clinical observations or non-randomised trials, 246 original basic science reports and only 26 were randomised controlled trials. These articles were published in 478 separate journals but with 36% of them being published in a core set of 23 journals. The H-index of these papers was 25 and there were 147 papers with 10 or more citations. Of the top 100 cited papers, 25% were published in five journals. Of the top cited papers, 48% were review articles, 18% were original basic science, and 7% were randomised clinical trials. Discussion This analysis shows a steady but modest increase in publications concerning cachexia with a strong pipeline of basic science research but still a relative lack of randomised clinical trials, with none exceeding 1000 patients. Research in cachexia is still in its infancy, but the solid basic science effort offers hope that translation into randomised controlled clinical trials may eventually lead to effective therapies for this troubling and complex clinical disease process.

The Social Environment’s Relationship With Frailty: Evidence From Existing Studies

Increasingly, policymakers assume that informal networks will provide care for frail older people. While the literature has mainly discussed the role of the family, broader social networks are also considered to be important. However, these social networks can diminish in later life. This systematic review investigates whether the social environment increases the risk of frailty or helps to prevent it. Findings from 15 original studies were classified using five different factors, which denoted five dimensions of the social environment: (a) social networks, (b) social support, (c) social participation, (d) subjective neighborhood experience, and (e) socioeconomic neighborhood characteristics. The discussion highlights that the social environment and frailty are indeed related, and how the neighborhood dimensions and social participation had more consistent results than social support and social networks. Conclusively, recommendations are formulated to contemplate all dimensions of the social environment for further research examining frailty and community care.

The influence of frailty syndrome on medication adherence among elderly patients with hypertension

BACKGROUND

Hypertension affects about 80% of people older than 80 years; however, diagnosis and treatment are difficult because about 55% of them do not adhere to treatment recommendations due to low socioeconomic status, comorbidities, age, physical limitations, and frailty syndrome.

AIMS

The purposes of this study were to evaluate the influence of frailty on medication adherence among elderly hypertensive patients and to assess whether other factors influence adherence in this group of patients.

METHODS AND RESULTS

The study included 296 patients (mean age 68.8±8.0) divided into frail (n=198) and non-frail (n=98) groups. The Polish versions of the Tilburg Frailty Indicator (TFI) for frailty assessment and 8-item Morisky Medication Adherence Scale for adherence assessment were used. The frail patients had lower medication adherence in comparison to the non-frail subjects (6.60±1.89 vs 7.11±1.42; P=0.028). Spearman's rank correlation coefficients showed that significant determinants with negative influence on the level of adherence were physical (rho =-0.117), psychological (rho =-0.183), and social domain (rho =-0.163) of TFI as well as the total score of the questionnaire (rho =-0.183). However, multiple regression analysis revealed that only knowledge about complications of untreated hypertension (β=0.395) and satisfaction with the home environment (β=0.897) were found to be independent stimulants of adherence level.

CONCLUSION

Frailty is highly prevalent among elderly hypertensive patients. Higher level of frailty among elderly patients can be considered as a determinant of lower adherence. However, social support and knowledge about complications of untreated hypertension are the most important independent determinants of adherence to pharmacological treatment.

Screening for Frailty in Canada's Health Care System: A Time for Action

As Canada's population ages, frailty - with its increased risk of functional decline, deterioration in health status, and death - will become increasingly common. The physiology of frailty reflects its multisystem, multi-organ origins. About a quarter of Canadians over age 65 are frail, increasing to over half in those older than 85. Our health care system is organized around single-organ systems, impairing our ability to effectively treat people having multiple disorders and functional limitations. To address frailty, we must recognize when it occurs, increase awareness of its significance, develop holistic models of care, and generate better evidence for its treatment. Recognizing how frailty impacts lifespan will allow for integration of care goals into treatment options. Different settings in the Canadian health care system will require different strategies and tools to assess frailty. Given the magnitude of challenges frailty poses for the health care system as currently organized, policy changes will be essential.
