Depression and frailty: concurrent risks for adverse health outcomes

Gait kinematic and kinetic characteristics among older adults with varying degrees of frailty: a cross-sectional study

The aim of this study was to investigate the differences in gait kinematics and kinetics among pre-frail, frail, and non-frail older adults during routine walking tasks. A total of 106 older adult participants were classified into frail, pre-frail, and non-frail groups based on the Fried frailty scale. Kinematic and kinetic data were acquired via a three-dimensional gait analysis system. Multivariate analysis of covariance (MANCOVA) was employed to assess the differences in gait kinematics and kinetics among the groups, followed by Bonferroni post-hoc tests. MANCOVA revealed significant differences in peak ankle plantar flexion, ankle range of motion (ROM), knee heel strike angle, and hip toe-off angle among the groups on the right side (P < 0.002). On the left side, significant differences were found in peak ankle plantar flexion, ankle ROM, and hip toe-off angle (P < 0.002). However, no significant differences in gait kinetics were observed among the three groups (P > 0.002). There is a weak correlation between gait kinematic parameters and dynamic postural stability. Compared with non-frail individuals, frail older adults reduced peak ankle plantar flexion, ankle ROM, and knee heel strike angle during walking. In contrast, the hip toe-off angle was found to be increased in the frail group.

Causal relationship between genetically predicted mental disorders and frailty: a bidirectional and multivariable mendelian randomization study

BACKGROUND

In observational studies, frailty has been strongly associated with mental disorders. However, the mechanisms underlying the association between frailty and mental disorders remain unclear.

METHODS

We conducted a two-sample Mendelian randomization (MR) study to assess the causal relationship between frailty, as measured by the frailty index (FI), and ten common mental disorders. The datasets involved European ancestry individuals and included measurements of the FI (N = 175,226), schizophrenia (SCZ; N = 320,404), major depressive disorder (MDD; N = 143,265), bipolar disorder (N = 337,199), insomnia (N = 462,341), obsessive-compulsive disorder (N = 33,925), anxiety disorders (N = 463,010), autism spectrum disorder (N = 46,351), anorexia nervosa (N = 14,477), opioid-related mental and behavioral disorders (N = 215,650), and mental and behavioral disorders due to use of other stimulants including caffeine (N = 215,570).

RESULTS

Two-sample MR analyses were performed using inverse variance weighting followed by various sensitivity and validation analyses. Genetically predicted SCZ (odds ratio [OR] = 1.019, 95% confidence interval [CI] 1.005-1.033) and MDD (OR = 1.211, 95% CI 1.092-1.343) had significant causal effects on FI. In the reverse MR analysis, we discovered that MDD was significantly and causally affected by FI (OR = 1.290, 95% CI 1.133-1.469). No causal links were identified between the FI and the other eight common mental disorders. In the Multivariable MR, the estimated MDD effect on FI is comparable to the univariate IVW estimate (OR = 1.298; 95% CI, 1.175 to 1.435), while the estimated SCZ effect on FI fails to be significant compared to the univariate estimate. The results of the sensitivity and validation analyses confirmed stabilization.

CONCLUSIONS

Our study found evidence of a causal relationship between SCZ, MDD, and frailty and explored the underlying mechanisms.

The Mediating Effect of Depression on Perceived Discrimination and Persistent Prescription Opioid Use Among Puerto Rican Adults

BACKGROUND

Stress indicators, including perceived discrimination and depression, have been linked with chronic diseases. Studies have also linked persistent prescription opioid use (PPOU) with depression. With increasing numbers of opioid overdose deaths among Hispanics (predominantly Puerto Rican) in Massachusetts, investigating how perceived discrimination and depression affect PPOU is relevant to public health efforts to address the opioid crisis. This study examined the effect of depression on PPOU and whether depression mediated the association between perceived discrimination and PPOU among Puerto Rican adults.

METHODS

Data derived from a prospective population-based Boston Puerto Rican Health Study, at baseline and ~2- and ~6-year follow-up, were used to estimate the association between perceived discrimination and PPOU. Baron and Kenny's method was used to examine the potential mediating effect of depression.

RESULTS

A total of 798 Puerto Rican adults (aged 56.5 ± 7.5 years, 72.9% women) participated in the study at all three time points, and 6.5% used prescription opioids persistently. Both depressive symptoms (Center for Epidemiological Studies Depression Scale score range: 0-60; OR = 1.03, 95% CI [1.00, 1.05], p = .03) and perceived discrimination (yes/no; OR = 2.43, 95% CI [1.28, 4.61], p = .006) were associated with PPOU. Depressive symptomatology partially mediated the effect of perceived discrimination on PPOU, by 10.3%.

CONCLUSIONS

Among Puerto Rican adults in Massachusetts, depressive symptomatology partially explained the effects of perceived discrimination on PPOU. Other unidentified factors could play a role in the relationship between perceived discrimination and PPOU. Discussion on the potential risks of PPOU should be considered among underserved populations experiencing chronic pain, discrimination, and depressive symptoms.

Associations between frailty, depression and risk of hospitalisation for infection: A large prospective cohort study

BACKGROUND

There is a considerable lack of epidemiological evidence on whether frailty, and frailty comorbid depression could increase the risk of infections in older adults. This study aimed to examine the prospective association between frailty, depression, and risk of infections.

METHODS

A total of 308,892 eligible participants were included. Linked hospital admission records (HES) were used to identify a primary or secondary diagnosis of depression, and infection. Frailty was assessed by Fried frailty phenotype indicators. Cox proportional hazard model was conducted to examine the associated risk between frailty, depression, comorbid frailty and depression and risk of incident infections. Results were stratified by age and gender.

RESULTS

During the follow-up, 74,749 (24.19 %) incident any infection cases were identified, the incidence density of any infection was 17.29/1000 person years. Frailty alone (HR = 1.38, 95 % CI: 1.33-1.43), depression alone (HR = 1.90, 95 % CI: 1.86-1.94), and comorbid frailty and depression (HR = 1.91, 95 % CI: 1.82-1.99) were associated with greater risks of any infections relative to participants with neither frailty nor depression. The associations between frailty alone, depression alone, comorbid frailty and depression, and any infections/most infection subtypes were significant for all age strata in both male and female.

LIMITATIONS

Frailty phenotype was assessed through the adapted Fried criteria, based on a mix of self-reported and objective measurements.

CONCLUSION

Frailty, depression, and comorbid frailty and depression were significantly associated with increased risk of incident infections.

Exploration of frailty trajectories and their associations with health outcomes in older gastric cancer survivors undergoing radical gastrectomy: A prospective longitudinal observation study

BACKGROUND

Frailty is commom among gastric cancer survivors and increases the burden of care.

AIMS

Our aims were to identify the frailty trajectories and investigate their associations with health outcomes in older gastric cancer survivors.

METHODS

We finally recruited 381 patients aged ≧60 who underwent radical gastrectomy and recorded frailty at discharge from the hospital, 1, 3, 6, and 12 months after surgery. Growth mixture modeling was used to investigate the frailty trajectories and linear regression models were used to examine their associations with health outcomes.

RESULTS

Three classes of frailty trajectories were identified: the "improving frailty", "maintaining frailty" and "deteriorating frailty". Compared with class 1, patients who followed class 2 and class 3 frailty trajectories were more likely to have more severe disability (β = -14.22, 95 % CI: -17.92, -10.61, P < 0.001; β = -48.34, 95 % CI: -52.25, -44.42, P < 0.001), worse quality of life (β = 10.89, 95 % CI: 7.71,14.08, P < 0.001; β = 34.82, 95 % CI: 31.46, 38.19, P < 0.001), and more frequency readmission within 1 year (β = 1.02, 95 % CI: 0.98, 1.06, P < 0.001; β = 2.10, 95 % CI: 2.01, 2.14, P < 0.001) after controlling potential confounders. However, class 2 and class 3 have no significant difference from class 1 in the total hospitalization costs (β = 1672.12, 95 % CI: -7145.95, 10496.19, P = 0.709; β = 7651.60, 95 % CI: -1670.28, 16793.47, P = 0.107).

CONCLUSIONS

Our study suggested the significant prognostic heterogeneity in frailty trajectories, and what we need to do is to identify patients with heterogeneous trajectory and intervene in them to reduce adverse outcomes, promote rational use of resources, and reduce the burden of care.

The Relationship of Frailty with Psychopathology, Childhood Traumas and Insecure Attachment in Young Adults: A Cross-Sectional Investigation

OBJECTIVE

Reciprocal connections exist between mental health and physical health, and conditions of cellular senescence/advanced biological age have been observed in association with certain psychiatric diseases. However, the construct of frailty has only preliminarily been explored in young adults and in relation to psychopathology so far. In the present study we aimed at further elucidating the relationships linking psychopathological phenomena with physical diseases in a sample of young adults.

METHODS

The sample was made of 527 Italian young adults (age range: 18-34). Participants were assessed on clinical/socio-demographic information as well as on the following measures: an ad hoc designed Frailty Index (FI), the Brief Symptroms Inventory (BSI), the Relationship Questionnaire (RQ), and the Childhood Trauma Questionnaire (CTQ).

RESULTS

Individuals with clinically-relevant psychopathological symptoms (based on established BSI cut-off scores) showed significantly higher FI values than individuals without clinically-relevant psychopathological symptoms (p<0.001). Higher levels of childhood traumatic experiences and higher levels of insecure forms of attachment were significantly associated with higher FI scores. The severity of preoccupied attachment style was significantly independently associated with higher FI scores also when multiple confounding variables were controlled for.

DISCUSSION

Our findings provide novel pieces of insight on the complex relationship of frailty, conceptualized as a measure of deficit accumulation and an indicator of functional status and biological age, with psychopathology, childhood traumas and insecure attachment, with potential implications for the clinical management of young individuals.

Depressive Symptom Subgroups and Their Association with Prevalent and Incident Cardiovascular Risk Factors in the Coronary Artery Risk Development in Young Adults (CARDIA) Study

BACKGROUND

We sought to identify depressive symptom subgroups in a community sample of young adults, investigate their stability over time, and determine their association with prevalent and incident cardiovascular disease (CVD) risk factors.

METHOD

Participants were 3377 adults from the Coronary Artery Risk Development in Young Adults study. Using latent class and latent transition analysis, we derived subgroups based on items of the 20-item version of the Center for Epidemiologic Studies Depression Scale in 1990, and examined patterns of change over a 10-year period (1990-2000). Cox regression models were used to examine associations between subgroup membership and prevalent (2000) and incident (2000 to 2016) obesity, hypertension, and diabetes.

RESULTS

Three baseline subgroups were identified and labeled: "No Symptoms" (63.5%), "Lack of Positive Affect" (PA, 25.6%), and "Depressed Mood" (10.9%). At 10-year follow-up, individuals in "No Symptoms" subgroup had the highest probability (0.84) of being classified within the same subgroup. Participants classified as "Lack of PA" were likely (0.46) to remain in the same subgroup or be classified as "No Symptoms." Participants in the "Depressed Mood" were most likely to transition to the "Lack of PA" subgroup (0.38). Overall, 30.5% of participants transitioned between subgroups, with 11.4% classified as "Worsening" and 19.1% as "Improving." Relative to the "No Symptoms Stable," other subgroups ("Depressed Stable," "Worsening," and "Improving") were associated with prevalent obesity and hypertension.

CONCLUSION

We identified distinct depressive symptom subgroups that are variably stable over time, and their change patterns were differentially associated with CVD risk factor prevalence.

Patterns, predictors, and outcomes of frailty trajectories in community-dwelling older adults: Results from the FREEDOM Cohort Study

OBJECTIVES

To identify subgroups of people with distinct frailty trajectories, identify baseline characteristics associated with these trajectories, and determine their coincident clinical outcomes.

DESIGN

This study examined the longitudinal database from the FREEDOM Cohort Study.

SETTING AND PARTICIPANTS

All 497 participants of the FREEDOM (French Acronym for "FRagilitéEtEvaluation àDOMicile" / In English "Frailty and Evaluation at Home") cohort requested a comprehensive geriatric assessment. Community-dwelling subjects over 75 years, or over 65 years with at least two comorbidities were included.

METHODS

Frailty was assessed using Fried's criteria, depression using the Geriatric Depression Scale (GDS) and cognitive function using the Mini Mental State Examination (MMSE) questionnaire. Frailty trajectories were modelled using k-means algorithms. Predictive factors were determined by multivariate logistic regression. Clinical outcomes included incident cognitive deficit, falls and hospitalization.

RESULTS

The trajectory models allowed determine four frailty trajectories: "robust stable" (Trajectory A, 26.8%), "pre-frail worsening to frailty" (Trajectory B, 35.8%), "frail improving to less frailty" (Trajectory C, 23.3%), and "frail worsening to more frailty" (Trajectory D, 14.1%). Trajectory B was associated with age (OR 1.2 (95CI, 1.05 - 1.17)), potential cognitive deficit/dementia (OR 2.01 (95CI, 1.01- 4.05)) and depressive symptoms (OR 2.36 (95CI, 1.36 - 4.12)). Hypertension was distinguishing factor between" trajectory B vs. C and D. Depressive symptoms were two time more associated with D (OR 10.51) vs. C (OR 4.55). The incidence of clinical outcomes was significantly increased in poor frailty trajectories.

CONCLUSIONS AND IMPLICATIONS

This study allowed to determine frailty trajectories among older subjects requested a comprehensive geriatric assessment. The more significant predictive factors associated with poor frailty trajectory were advanced in age, potential cognitive deficit/dementia, depressive symptoms and hypertension. This emphasizes the need for adequate measures to controlled hypertension, depressive symptoms and to maintain or improve cognition in older adults.

Preoperative frailty and adverse outcomes following coronary artery bypass grafting surgery in US veterans

BACKGROUND

Contemporary guidelines emphasize the value of incorporating frailty into clinical decision-making regarding revascularization strategies for coronary artery disease. Yet, there are limited data describing the association between frailty and longer-term mortality among coronary artery bypass grafting (CABG) patients.

METHODS

We conducted a retrospective cohort study (2016-2020, 40 VA medical centers) of US veterans nationwide that underwent coronary artery bypass grafting (CABG). Frailty was quantified by the Veterans Administration Frailty Index (VA-FI), which applies the cumulative deficit method to render a proportion of 30 pertinent diagnosis codes. Patients were classified as non-frail (VA-FI ≤ 0.1), pre-frail (0.1 < VA-FI ≤ 0.2), or frail (VA-FI > 0.2). We used Cox proportional hazards models to ascertain the association of frailty with all-cause mortality. Our primary study outcome was 5-year all-cause mortality; the co-primary outcome was days alive and out of the hospital within the first postoperative year.

RESULTS

There were 13,554 CABG patients (median 69 years, 79% White, 1.5% women). The mean pre-operative VA-FI was 0.21 (SD: 0.11); 31% were pre-frail (VA-FI: 0.17) and 47% were frail (VA-FI: 0.31). Frail patients were older and had higher co-morbidity burdens than pre-frail and non-frail patients. Compared with non-frail patients (13.0% [11.4, 14.7]), there was a significant association between frail and pre-frail patients and increased cumulative 5-year all-cause mortality (frail: 24.8% [23.3, 26.1]; HR: 1.75 [95% CI 1.54, 2.00]; pre-frail 16.8% [95% CI 15.3, 18.4]; HR 1.2 [1.08,1.34]). Compared with non-frail patients (mean 362[SD 12]), pre-frail (mean 361 [SD 14]; p < 0.01) and frail patients (mean 358[SD 18]; p < 0.01) spent fewer days alive and out of the hospital in the first postoperative year.

CONCLUSIONS

Pre-frailty and frailty were prevalent among US veterans undergoing CABG and associated with worse mid-term outcomes. Given the high prevalence of frailty with attendant adverse outcomes, there may be an opportunity to improve outcomes by identifying and mitigating frailty before surgery.

Depressive Symptoms Partially Mediate the Association of Frailty Phenotype Symptoms and Cognition for Females but Not Males

OBJECTIVES

We aimed to evaluate whether depressive symptoms mediated the relationship between frailty phenotype and cognitive function by sex.

METHODS

Data came from the Health and Retirement Study from 2012-2016. The outcome was measured by Fried's frailty criteria, our outcome was continuous global cognition, and mediator was depressive symptoms. We used mediation analysis, stratified by sex, to estimate the direct and indirect effects of frailty symptoms on cognition mediated by depressive symptoms.

RESULTS

Males had a larger total effect (β= -0.43; 95% CI: -0.66, -0.02) for lower cognitive score for each increase in frailty symptom compared to females (β= -0.28; 95% CI: -0.47, -0.08). A significant indirect effect from frailty phenotype to cognition was found through depressive symptoms for females but not males.

CONCLUSION

These results highlight the importance of identifying individuals with frailty and depressive symptoms to monitor and provide interventions to preserve cognitive function.

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.

Frailty and affective disorders throughout adult life: A 5-year follow-up of the Lifelines Cohort Study

BACKGROUND

Frailty is an important concept for risk stratification in clinical practice, but it is hardly acknowledged at all in mental healthcare settings. This paper aims to assess the impact of frailty on the course of depression and anxiety, and the impact of these affective disorders on the course of frailty.

METHODS

Lifelines, a prospective population-based cohort study, evaluated 167,729 people living in the northern Netherlands. Frailty was based on the deficit accumulation model, which resulted in a 60-item frailty index (FI) at baseline and a 35-item FI at baseline and 5-year follow-up. Current depressive and anxiety disorders were assessed with the Mini International Neuropsychiatric Interview according to DSM-IV criteria. Bidirectional associations between frailty and affective disorders were investigated using separate multivariable regression analyses in younger (<60 years) and older adults (≥60 years).

RESULTS

The FI was associated with the onset of a depressive disorder (younger adults: odds ratio [OR] = 1.12; 95% confidence interval [CI] 1.11-1.13; older adults: OR = 1.13; 95% CI 1.09-1.16) as well as any anxiety disorder (younger adults: OR = 1.10; 95% CI 1.09-1.10; older adults: OR = 1.07; 95% CI 1.04-1.09). The other way around, depressive disorder and anxiety disorders were associated with an accelerated increase of frailty over time (depressive disorder: younger adults: beta [β] = 0.03, p < 0.001; older adults: β = 0.04, p < 0.001; and any anxiety disorder: younger adults: β = 0.02, p < 0.001; older adults: β = 0.01, p < 0.142), although the effect of anxiety disorders was less equivocal among older adults.

CONCLUSIONS

Affective disorders are reciprocally related to frailty. Results with respect to the impact of anxiety disorders on frailty suggest most impact at lower levels of frailty. Our results might imply that interventions to slow biological aging should be broadened towards younger and middle-aged people as well as non-frail older patients. To develop targeted treatment, future clinical and epidemiologic studies on the underlying pathways of this bidirectional association are needed.

Frailty in geriatric psychiatry inpatients: a retrospective cohort study

OBJECTIVE

We aimed to evaluate the prevalence, clinical determinants, and consequences (falls and hospitalization) of frailty in older adults with mental illness.

DESIGN

Retrospective clinical cohort study.

SETTING

We collected the data in a specialized psychogeriatric ward, in Boston, USA, between July 2018 and June 2019.

PARTICIPANTS

Two hundred and fourty-four inpatients aged 65 years old and over.

MEASUREMENTS

Psychiatric diagnosis was based on a multi-professional consensus meeting according to DSM-5 criteria. Frailty was assessed according to two common instruments, that is, the FRAIL questionnaire and the deficit accumulation model (aka Frailty Index [FI]). Multiple linear regression analyses were conducted to evaluate the association between frailty and sample demographics (age, female sex, and non-Caucasian ethnicity) and clinical characteristics (dementia, number of clinical diseases, current infection, number of psychotropic, and non-psychotropic medications in use). Multiple regression between frailty assessments and either falls or number of hospital admissions in the last 6 and 12 months, respectively, were analyzed and adjusted for covariates.

RESULTS

Prevalence of frailty was high, that is, 83.6% according to the FI and 55.3% according to the FRAIL questionnaire. Age, the number of clinical (somatic) diseases, and the number of non-psychotropic medications were independently associated with frailty identified by the FRAIL. Dementia, current infection, the number of clinical (somatic) diseases, and the number of non-psychotropic medications were independently associated with frailty according to the FI. Falls were significantly associated with both frailty instruments. However, we found only a significant association for the number of hospital admissions with the FI.

CONCLUSION

Frailty is highly prevalent among geriatric psychiatry inpatients. The FRAIL questionnaire and the FI may capture different forms of frailty dimensions, being the former probably more associated with the phenotype model and the latter more associated with multimorbidity.

The influence of multiple frailty profiles on institutionalization and all-cause mortality in community-living older adults

BACKGROUND

Frailty in older adults is associated with adverse geriatric outcomes. Physical frailty is often accompanied by problems in the cognitive, psychological, and social domains. This study investigated the ability of physical frailty combined with other health domains to predict institutionalization and mortality.

METHODS

A national sample of 9171 Koreans aged 65 years or older were surveyed at baseline in 2008 and 3 year follow-up. Those who were prefrail or frail according to the Fried criteria were conceived to have physical frailty. Psychological frailty, cognitive frailty, and social frailty were defined as having depressive symptoms, cognitive impairment, and social vulnerabilities, respectively, in addition to physical frailty. Using Cox proportional hazards and competing-risks regression, the risk of mortality and institutionalization by the number and profiles of different frailty domains was analysed.

RESULTS

At baseline, the 9171 participants were aged 73.1 (±6.8) years on average (median: 72, range: 65 to 103), and 59.2% were women. Multidomain frailty was highly prevalent (49.3%), with 6.1% concurrently displaying frailty in all four domains (mixed frailty). The risk of negative health outcomes increased with frailty in a higher number of domains with a subhazard ratio (SHR) of 3.48 (95% confidence interval [CI]: 1.83, 6.62; P < 0.001) for institutionalization and a hazard ratio (HR) of 3.95 (95% CI: 2.62, 5.93; P < 0.001) for mortality among those presenting mixed frailty. Psychological frailty (depressive symptoms combined with physical frailty) was strongly predictive of institutionalization (SHR = 2.85; 95% CI: 1.45, 5.59; P = 0.002) and mortality (HR = 2.47; 95% CI: 1.61, 3.78; P < 0.001). When combined with physical frailty and either depressive symptoms or social vulnerabilities, cognitive impairment also exhibited a significantly elevated risk of negative events. Physical frailty alone was not a strong predictor of adverse events, especially for mortality (HR = 1.13; 95% CI: 0.77, 1.67; P = 0.53).

CONCLUSIONS

Co-occurrence of physical frailty with other domains is common in late life. The presence of frailty in multiple domains raises the risk of adverse outcomes, with the effects varying by multidimensional profiles.

The role of frailty in the association between depression and fall risk among older adults

OBJECTIVES

Although there is a recognized association between depression and greater fall risk among older adults, the mechanisms explaining this association are unclear. This study evaluated the role of frailty, a common geriatric syndrome, in determining greater risk of falls among older adults with depression.

METHOD

We used longitudinal data from three biennial waves of the Health and Retirement Study (HRS; 2010-2014). The sample included community-dwelling survey respondents age ≥ 65 who participated in objective physiological measures. Major Depression (MD) was measured using Composite International Diagnostic Interview for depression short form. Frailty was measured using criteria outlined in the frailty phenotype model. Causal mediation analysis was used to differentiate the direct effect of depression and indirect effect mediated by frailty on falls, fall injuries, and multiple falls.

RESULTS

Major depression was associated with significantly greater odds of experiencing a fall (OR: 1.91; 95% CI: 1.31, 2.77), fall injury (OR: 1.86; 95% CI: 1.17, 2.95), and multiple falls (OR: 2.26; 95% CI: 1.52, 3.37) over a two-year period. Frailty was a significant mediator of the effects of depression on falls and multiple falls, accounting for approximately 18.9% and 21.3% of the total effects, respectively. We found no evidence of depression-frailty interaction. Sensitivity analyses showed that results were robust to unmeasured confounding and alternative operationalizations of depression.

CONCLUSION

Frailty explains a significant proportion of increased likelihood of falls among older adults with depression. Treatment and management of frailty symptoms may be an important components of fall prevention among older adults with depression.

Frailty and predictive factors in Chinese hospitalized patients with chronic heart failure: A Structural Equation Model Analysis

AIMS

Frailty is closely related to the prognosis and quality of life of patients with heart failure (HF). However, the predictors of it are still unclear. Our study aimed to describe the frailty status of Chinese hospitalized patients with heart failure and explore predictive factors guided by Theory of Unpleasant Symptoms.

METHODS AND RESULTS

In this cross-sectional descriptive study, questionnaire-based survey was conducted among 323 patients hospitalized with heart failure in three tertiary hospitals in Wuhan, China. Frailty was measured by the Tilburg Frailty Indicator (TFI) in this study. The model based on Theory of Unpleasant Symptoms fits the sample well (root mean square error of approximation = 0.063, goodness of fit index = 0.977, normed fit index = 0.901, comparative fit index = 0.940). Frailty among Chinese patients hospitalized with heart failure was at high level (TFI = 6.57 ± 3.05). General demographic characteristics (older age, female gender, lower education level, and medical payment method), physical factors (higher New York Heart Association cardiac function class), psychological factors (more severe depression), and social factors (poorer social support) were significant predictors of more severe frailty (p < 0.05). Depression played an important mediating role in this study.

CONCLUSIONS

Theory of Unpleasant Symptoms can be used to guide the research on the frailty of heart failure patients. It is suggested to strengthen emotional support and health education for heart failure patients in China. In addition, more attention should be paid to the less educated population by providing more personalized health guidance.

Frailty, depression risk and 10-year hospitalization in older adults. The FRADEA study

OBJECTIVES

To determine whether the interaction between frailty status and depression risk is associated with hospitalization density in older adults.

METHODS

Ongoing cohort study in 794 subjects aged over 70 years from Albacete (Spain). Data were collected on depression risk, frailty, hospitalizations, and covariates. Participants were categorized into six groups.

RESULTS

Adjusted hospitalization risk was higher for groups of prefrail/-non depression risk (HR 1.48; 95% confidence interval (CI) 1.16-1.89), prefrail/depression risk (HR 1.73; 95% CI 1.29-2.30), frail/non depression risk (HR 1.79; 95% CI 1.22-2.62), and frail/depression risk (HR 2.12; 95% CI 1.49-3.02), compared with robust/non depression risk group (p<0.01). Frail and prefrail groups presented increased hospitalization density in the first four follow-up years.

CONCLUSIONS

Depression risk changes the yearly probabilities of hospitalization in prefrail and frail groups, increasing them in the first years. Depression risk should be monitored in prefrail and frail older adults as an independent risk factor for hospitalization.

The Influence of Depressive Mood on Mortality in Elderly with Different Health Status: Evidence from the Taiwan Longitudinal Study on Aging (TLSA)

Depression and related syndromes are well identified in older adults. Depression has been reported to increase the incidence of a multitude of somatic disorders. In older adults, the severity of depression is associated with higher mortality rates. The aim of the study is to examine whether the effect of depression screening on mortality is different between individuals with different physical health status. In order to meet this aim, we will first reprove the relationship between depression and mortality rate, and then we will set a subgroup analysis by using self-reported health (SRH) status. Our data source, Taiwan Longitudinal Study on Aging (TLSA), is a population-based prospective cohort study that was initiated by the Health Promotion Administration, Ministry of Health and Welfare, Taiwan. The depression risk was evaluated by 10-items Center for Epidemiologic Studies Depression (CES-D-10), we set 3 CES-D-10 cutting points (5, 10, and 12) and cut our subjects into four groups. Taking mortality as an end point, we use the Taiwan National Death Registry (TNDR) record from 1999 to 2012. Self-rated health (SRH) was taken as an effect modifier between depression and mortality in the elderly group, and stratification took place into three groups (good, fair, poor). The case numbers of 4 CES-D-10 groups were 2253, 939, 285 and 522, respectively. After dividing into 4 CES-D-10 groups, the mortality prevalence rose as the CES-D-10 level grew (40.7%, 47.82%, 54.39% and 67.62%, respectively). In the subgroup analysis, although the p-value of log-rank test showed <0.05 in three groups, as the SRH got worse the Hazard Ratio became more significant (p = 0.122, 0.033, <0.001, respectively). Kaplan−Meier (K-M) survival estimates for different CES-D groups in SRH were poor, and we can see the curves representing second and third CES-D group going almost together, which may suggest the cutting point of CES-D-10 in predicting depression risk should be adjusted in the relatively unhealthy elderly. The importance of the relationship between depression and mortality is re-emphasized in our study. Moreover, through joining SRH in our analysis, we can conclude that in self-rated poor health any sign of depression may lead to a rise in mortality. Therefore, we should pay attention to the old age group’s psychological status, and remember that depressive mood should be scrutinized more carefully in the elderly who feel themselves to be unhealthy.

Exploring life and help-seeking experiences regarding suicidal ideations among nursing home residents

Globally, older adults, especially nursing home residents, are at a higher risk of suicide. This study examined the life of nursing home residents with suicidal ideations and their help-seeking experiences. A qualitative analysis of 19 semi-structured interviews was conducted. Results indicate that suicidal ideations among nursing home residents correlates with their negative life experiences, both personally and institutionally. In terms of their life experiences, themes included the desire for death, emotional loneliness, a state of discomfort arising from incapacity, feeling like a burden on children, and dealing with the low-quality service. Older adults' negative attitudes toward seeking assistance as well as limited resort resources and ineffective help-seeking hinder them from finding more support or treatment. This study adds to a growing body of research on late-life suicide in institutional settings, and relevant findings can serve as references in improving nursing home residents' life quality and developing suicide-prevention strategies.

Frailty and Different Exercise Interventions to Improve Gait Speed in Older Adults after Acute Coronary Syndrome

Background and Objectives: The world’s population is rapidly aging, and it is estimated that, by 2050, every sixth person on earth will be older than 65 years. Around 30% of older adults entering cardiac rehabilitation (CR) meet the criteria of frailty. Frailty identification has not been included in the routine evaluation of CR patients yet, and there is a lack of evidence on what training regimen for improving physical performance in frail people is optimal. Therefore, the aim of our study was to determine the prevalence of frailty and to evaluate the effect of two different complementary training programs on the gait speed of older vulnerable and frail patients with acute coronary syndrome and mid-range-to-preserved left ventricular ejection fraction (≥40%) during short-term CR. Materials and Methods: This randomized controlled trial was conducted from January 2020 to September 2021. CR participants (n = 97) with a mean age of 73.1 ± 5.3 years were randomly allocated into three groups: control (CG, n = 32), intervention-1 (IG-1, n = 32) and intervention-2 (IG-2, n = 33). The patients of all three groups attended a usual inpatient CR program, and two intervention groups additionally received different resistance and balance training programs 3 days a week: the IG-1 underwent complementary training with traditional means of physical therapy, while the IG-2 underwent complementary training with mechanical devices. The mean CR duration was 18.9 ± 1.7 days. Frailty was assessed with the Edmonton Frail Scale, and the 5 m walk test was used to evaluate gait speed. Results: Frailty was determined in 37.1% of participants, and 42.3% met the criteria of being vulnerable. After CR, the gait speed of frail and vulnerable patients significantly improved in all three groups (p < 0.05). In the IG-2, slow gait speed was reversed to normal in the overwhelming majority of patients (p < 0.05), while the CG had the greatest proportion of patients who remained to be slow after CR (p < 0.05). Conclusions: A considerable part of patients entering CR are frail or vulnerable; therefore, it is of crucial importance to assess frailty status in all older people. All three CR programs improved gait speed in frail and vulnerable older patients with ischemic heart disease. Complementary resistance and balance training with mechanical devices more effectively reversed slow gait speed to normal during short-term CR.

Assessing frailty indicators in the context of psychiatric disorder: A Delphi consensus study

OBJECTIVES

Substantial construct overlap exists between indicators of frailty and symptoms of some psychiatric disorders. This study aimed to gain consensus of expert academic opinion on the potential impact of psychiatric illness on frailty assessment and how best to conceptualise and measure frailty indicators in the context of psychiatric symptoms.

DESIGN

A classic Delphi approach was employed across two studies to achieve consensus: The first-round questionnaire consisted of open-ended questions, analysed through content analysis. The results informed the development of statements for participants to rate their agreement with in subsequent Delphi rounds. Statements with ≥66% agreement were accepted. Delphi Study 1 recruited experts in frailty assessment (n = 13) and Delphi Study 2 recruited experts in frailty and psychiatric disorder (n = 8). Experts were recruited globally.

RESULTS

Overall, 40% of Delphi Study 1 statements and 43% of Delphi Study 2 statements were accepted. Primarily, consensus was reached for statements concerning the influence of depression/anxiety on frailty assessment and potential methods of conceptualising and measuring frailty indicators in the context of psychiatric symptoms. Little consensus was reached concerning the ease and importance of differentiating between frailty indicators and psychiatric assessment criteria with substantial overlap.

CONCLUSIONS

The Delphi studies provide a novel exploration and consensus of expert academic opinions concerning the assessment of frailty indicators in the context of psychiatric symptoms. The results will inform future research into the adaptation or development of a frailty assessment tool specifically for use in older adult psychiatric populations.

Conclusiones

La fragilidad es un síndrome multifactorial de elevada prevalencia en los mayores de 70 años, en el que además de los criterios de fragilidad de Fried deben de ser analizados aspectos del estado de salud, funcionales, cognitivos-afectivos y sociales.

Antidepressant Use Partially Mediates the Association Between Depression and Risk of Falls and Fall Injuries Among Older Adults

BACKGROUND

The association between depression and fall risk in older adults is recognized, yet the mechanisms underlying this association are unclear. This study estimated the mediating role of antidepressant use in the association between depression and falls and fall injuries.

METHODS

Longitudinal data from the Health and Retirement Study (2004-2006) were linked with medication data from the Prescription Drug Study (2005). The sample included community-dwelling adults aged ≥65 with data on depression and medication use (n = 3565). Depression was measured using 2 independent survey tools: Composite International Diagnostic Interview for depression short form and an 8-item version of the Center for Epidemiological Studies-Depression scale. We used causal mediation analysis to estimate and compare the direct and indirect (mediated by antidepressant use) effects of depression on falls and fall injuries.

RESULTS

Individuals with major depressive disorder were significantly more likely to experience a fall (OR: 1.92; 95% CI: 1.41, 2.62) and a fall injury (OR: 1.67; 95% CI: 1.09, 2.55) over 2 years. Indirect effect estimates showed that antidepressant medication use accounted for approximately 19% and 18% of the association between major depressive disorder and falls and fall injuries, respectively. Results were similar when using an alternative depression measure and when considering only selective serotonin reuptake inhibitor antidepressants.

CONCLUSIONS

Antidepressant use explains a significant proportion, but not a majority, of the association between depression and greater fall risk. Treatment benefits of antidepressants should be considered with, and may outweigh, concerns about increased risk of falls associated with antidepressant use.

Frailty, depression risk, and 10-year mortality in older adults: the FRADEA study

OBJECTIVES

To investigate if depression risk modifies the association between frailty and mortality in older adults.

DESIGN

Ongoing cohort study.

SETTING

Albacete city, Spain.

PARTICIPANTS

Eight hundred subjects, 58.8% women, over 70 years of age from the Frailty and Dependence in Albacete (FRADEA) study.

MEASUREMENTS

Frailty phenotype, Geriatric Depression Scale (GDS), comorbidity, disability, and drug use were collected at baseline. Six groups were categorized: (G1: non-frail/no depression risk; G2: non-frail/depression risk; G3: prefrail/no depression risk; G4: prefrail/depression risk; G5: frail/no depression risk; and G6: frail/depression risk). Mean follow-up was 2542 days (SD 1006). GDS was also analyzed as a continuous variable. The association between frailty and depression risk with 10-year mortality was analyzed.

RESULTS

Mean age was 78.5 years. Non-frail was 24.5%, prefrail 56.3%, frail 19.3%, and 33.5% at depression risk. Mean GDS score was 3.7 (SD 3.2), increasing with the number of frailty criteria (p < 0.001). Ten-year mortality rate was 44.9%. Mortality was 21.4% for the non-frail, 45.6% for the prefrail, and 72.7% for the frail participants, 56% for those with depression risk, and 39.3% for those without depression risk. Mean survival times for groups G1 to G6 were, respectively, 3390, 3437, 2897, 2554, 1887, and 1931 days. Adjusted mortality risk was higher for groups G3 (HR 2.1; 95% confidence interval (CI) 1.4-3.1), G4 (HR 2.5; 95% CI 1.7-3.8), G5 (HR 3.8; 95% CI 2.4-6.1), and G6 (HR 4.0; 95% CI 2.6-6.2), compared with G1 (p < 0.001). Interaction was found between frailty and depression risk, although they were independently associated with mortality.

CONCLUSIONS

Depression risk increases mortality risk in prefrail older adults but not in non-frail and frail ones. Depression should be monitored in these older adults to optimize health outcomes. Factors modulating the relationship between frailty and depression should be explored in future studies.

Risk factors associated with frailty in older adults with type 2 diabetes: A cross-sectional study

AIMS AND OBJECTIVES

The aims of the study were to (i) estimate the prevalence of frailty among older adults with type 2 diabetes, and (ii) investigate risk factors associated with frailty in the study group.

BACKGROUND

The high prevalence of frailty among older adults and its adverse health impacts including higher risks for physical disabilities and a higher mortality rate is quickly evolving to become an important public health issue.

DESIGN

A cross-sectional design.

METHODS

Data were collected from the Clinical Diabetes Centre of our study group. Frailty was assessed using the Chinese version of the Tilburg frailty indicator. Other questionnaires included Activities of Daily Living, Mini-Mental State Examination, Taiwan Geriatric Depression Scale and Instrumental Activities of Daily Living. Multivariable logistic regression was established to identify factors associated with frailty. The STrengthening the Reporting of OBservational studies in Epidemiology checklist was used preparing the manuscript.

RESULTS

A total of 248 subjects were recruited in this study, a total of 66 participants had frailty (26.6%). Our results showed that factors including age, number of chronic diseases, cerebrovascular accident, renal diseases, frequency of falling, frequency of hyperglycaemia, Activities of Daily Living, depression, Mini-Mental State Examination, and Instrumental Activities of Daily Living ≧1 task disability were correlated with frailty in older adults with type 2 diabetes. After adjusting for confounding factors, multivariate logistic regression analyses showed a significant increase in the probability of frailty by 1.72-times when comparing type 2 diabetes subjects with depression to those without depression.

CONCLUSION

This study revealed that depression is a significant factor associated with the occurrence of frailty among older adults with type 2 diabetes.

RELEVANCE TO CLINICAL PRACTICE

Our results provided strong clinical evidence showing depression as an important factor associated with the risk of frailty in older individuals with type 2 diabetes. We recommend early detection via routine screenings for symptoms of depression during diabetes care to achieve early prevention or the delay of frailty and its implicated adverse health consequences.

Impact of childhood trauma on multidimensional frailty in older patients with a unipolar depressive-, anxiety- or somatic symptom disorder

OBJECTIVES

Frailty marks an increased risk for adverse health outcomes. Since childhood trauma is associated with the onset of physical and mental health diseases during the lifespan, we examined the link between childhood trauma and multidimensional frailty.

METHOD

A cross-sectional study embedded in a clinical cohort study (ROM-GPS) of older (≥60 years) patients (n=182) with a unipolar depressive-, anxiety- and/or somatic symptom disorder according to DSM-criteria referred to specialized geriatric mental health care. Frailty was assessed with the Tilburg Frailty Indicator (TFI), comprising a physical, psychological, and social dimension. Physical, sexual and psychological abuse and emotional neglect before the age of 16 years was measured with a structured interview.

RESULTS

Of 182 patients, 103 (56.6%) had experienced any childhood trauma and 154 (84.6%) were frail (TFI sum score ≥5). Linear regression analyses, adjusted for lifestyle, psychological and physical-health factors, showed that the presence of any type of childhood trauma was not associated with the TFI sum score, however when considered separately, physical abuse was (ß=0.16, p=.037). Regarding the specific frailty dimensions, any childhood trauma was associated with social frailty (ß=0.18, p=.019), with emotional neglect as main contributor.

CONCLUSION

These findings demonstrate a complex link between different types of childhood trauma and multidimensional frailty among older psychiatric patients. Regarding the three dimensions of frailty, social frailty seems most affected by childhood trauma. This may have been underestimated until now and should receive more attention in clinical care and future research.

The relationship of frailty and disability with suicidal ideation in late life depression

OBJECTIVES

Frailty and disability are commonly found in Late Life Depression (LLD) and have been associated with increased depression severity, health comorbidities and mortality. Additionally, physical frailty has been associated with suicide in later life, independent of presence of a mood disorder. The objective of our study was to assess the associations of physical frailty and functional disability with suicidal ideation, controlling for depression severity and demographic factors, in an older depressed sample.

METHODS

This study used data from community-dwelling older adults with major depression. Eligible participants were ≥ 65 years old, completed measures of depression symptom severity (Hamilton Depression Rating Scale-24 item; HDRS-24), current suicidal ideation (Geriatric Suicide Ideation Scale; GSIS), and physical frailty/functional capacity measures.

RESULTS

Participants were 88 older adults with a mean age of 71.5 (SD = 6.0) and 66% of the sample was female. Poorer performance on frailty measures of gait speed (B = .239, p = .003) and muscle weakness (B = -.218, p = .01) were significantly associated with higher levels of suicidal ideation, independent of depression severity and demographic factors. Functional disability was also significantly related to suicide ideation, specifically impairment in financial capacity (B = -.290, p = .008), social interaction (B = .408, p < .001), and communication skills (B = .373, p = .001).

CONCLUSION

Our findings show that, in LLD, frailty and functional disability are significantly associated with higher levels of suicide ideation, independent of depression symptom severity.

Could Frailty be an Explanatory Factor of the Association between Depression and Other Geriatric Syndromes in Later Life?

OBJECTIVES

This study aimed to investigate whether frailty could be an explanatory factor of the association between depression and the number of geriatric syndromes.

METHODS

Cross-sectional baseline data from a cohort study (MiMiCS-FRAIL) were analyzed in a sample of 315 older adults. Depression was measured according to DSM-5 criteria and a self-report questionnaire (PHQ-9). Frailty was assessed according to the FRAIL questionnaire and a 30-item Frailty Index (FI). We considered six geriatric syndromes. Multiple linear regression analyses were performed and adjusted for potential confounders.

RESULTS

Multiple linear regression analyses yielded significant associations between depression and geriatric syndromes. These associations decreased substantially in strength when frailty was added to the models. Findings were consistent for different definitions of depression and frailty.

CONCLUSIONS

Among depressed patients, frailty may be hypothesized as a causal pathway toward adverse health outcomes associated with depression. Longitudinal studies should explore the causality of this association.

CLINICAL IMPLICATIONS

Frailty should be treated or prevented in order to minimize the impact of other geriatric syndromes among depressed older adults. Screening for frailty would be of utmost importance in mental health care, as frailty is neglected especially in this field. Integrated care models are crucial for clinical practice in mental illness care.

Longitudinal Association between Late-Life Depression (LLD) and Frailty: Findings from a Prospective Cohort Study (MiMiCS-FRAIL)

OBJECTIVES

The aim of the present study was to investigate whether late-life depression (LLD) is associated with incident frailty over time.

DESIGN

Prospective cohort study, one-year follow-up.

SETTING

Geriatric outpatient clinic, Southwestern of Brazil.

PARTICIPANTS

181 follow-up participants aged 60 years or over.

MEASUREMENTS

Depressive disorders were classified as Major Depressive disorder (MDD) or Subthreshold Depression (STD) according to DSM-5 criteria. Depressive symptoms were assessed with validated versions of 15-item Geriatric Depression Scale (GDS-15) and 9-item Patient Health Questionnaire (PHQ-9). We performed binary logistic regressions to estimate the odds ratio (OR) for frailty in LLD adjusting for multiple confounders. Participants who were frail at baseline were excluded from the analyses according to measures of frailty (FRAIL questionnaire and 36-item Frailty Index, FI-36). We also estimated the risk ratio or relative risk (RR) and the risk difference (RD) for incident frailty.

RESULTS

We observed a 2 to 4-fold increased risk for incident frailty among participants with LLD. The presence of a depressive disorder was significantly associated with the onset of frailty (adjusted OR for FRAIL and FI-36: 3.07 [95% CI = 1.03 - 9.17] and 3.76 [95% CI = 1.09 - 12.97], respectively. Notably, the risk for frailty due to LLD was significantly higher with the FI-36 compared to the FRAIL (RR: 3.03 versus 2.23). RD was of 17.3% and 12.7% with the FRAIL and the FI-36, respectively.

CONCLUSION

Our data support the association between LLD and incident frailty over one year among geriatric outpatients, reinforcing longitudinal evidence from population-based studies.

Frailty and depression predict instrumental activities of daily living in older adults: A population-based longitudinal study using the CARE75+ cohort

Objectives

To evaluate if depression contributes, independently and/or in interaction with frailty, to loss of independence in instrumental activities of daily living (ADL) in older adults with frailty.

Methods

Longitudinal cohort study of people aged ≥75 years living in the community. We used multi-level linear regression model to quantify the relationship between depression (≥5 Geriatric Depression Scale) and frailty (electronic frailty index), and instrumental activities of daily living (Nottingham Extended Activities of Daily Living scale; range: 0–66; higher score implies greater independence). The model was adjusted for known confounders (age; gender; ethnicity; education; living situation; medical comorbidity).

Results

553 participants were included at baseline; 53% were female with a mean age of 81 (5.0 SD) years. Depression and frailty (moderate and severe levels) were independently associated with reduced instrumental activities of daily living scores. In the adjusted analysis, the regression coefficient was -6.4 (95% CI: -8.3 to -4.5, p<0.05) for depression, -1.5 (95% CI: -3.8 to 0.9, p = 0.22) for mild frailty, -6.1 (95% CI: -8.6 to -3.6, p<0.05) for moderate frailty, and -10.1 (95% CI: -13.5 to -6.8, p<0.05) for severe frailty. Moreover, depression interacted with frailty to further reduce instrumental activities of daily living score in individuals with mild or moderate frailty. These relationships remained significant after adjusting for confounders.

Conclusion

Frailty and depression are independently associated with reduced independence in instrumental activities of daily living. Also, depression interacts with frailty to further reduce independence for mild to moderately frail individuals, suggesting that clinical management of frailty should integrate physical and mental health care.

Complex mental health needs in older people living with frailty

Frailty describes a state of health whereby people develop multiple or cumulative deficits in physiological systems over the life course, leading to vulnerability and being less able to respond to acute and/or physiological stressors, which at times may be relatively minor. Mental health should be an important consideration in the assessment and management of frailty in older people. This article provides an overview and clinical perspective on the evidence relating to frailty and mental health assessment and management.

The Longitudinal Associations between Physical Health and Mental Health among Older Adults

OBJECTIVES

This study examines the lead-lag relationship between physical and mental health among older adults.

METHOD

Data are collected from 16,417 older adults aged 50 years and older participating in the biannual Health and Retirement Study (HRS). Participants were assessed on up to 11 measurement points over a 21-year period from 1994 to 2014. Physical health was measured as a composite of chronic diseases, functional limitations, and difficulties in basic and instrumental activities of daily living. Mental health was measured with the modified CES-D. Bivariate latent change score models (BLCSM) were estimated.

RESULTS

Both physical and mental health declined in the observed years, with slower declining rates over time. A reciprocal relationship emerged, with the prior level of physical health acting as the leading indicator of subsequent change in mental health, and the prior mental health state acting as the leading indicator of subsequent changes in physical health. Additionally, the influence of physical health on mental health changes was larger than the corresponding effect of mental health on subsequent physical health.

CONCLUSION

This study demonstrates the reciprocal relationship between physical and mental health in later adulthood and highlights the need to pay attention to the mental health of older people with physical health problems.

Depression, physical function, and disease activity associated with frailty in patients with rheumatoid arthritis

OBJECTIVES

To investigate the clinical and psychosocial backgrounds of frailty in rheumatoid arthritis (RA) patients.

METHODS

Patients with RA between 40 and 79 years of age who visited university hospitals in an urban area were recruited. Well-validated self-reported questionnaires were used to evaluate patient physical function (Health Assessment Questionnaire, HAQ), depressive symptoms (Beck Depression Inventory-II, BDI-II), and frailty (Kihon Checklist). A 28-point Disease Activity Score (DAS-28) was calculated to evaluate RA disease activity.

RESULTS

A total of 375 RA patients, 323 of whom were women, were enrolled (average age: 65.2 ± 9.7 years; average disease duration: 16.6 ± 11.9 years). The prevalence rates of frailty, working-age (40-64 years), young-old (65-74 years), and old-old (≥75 years) patients were 18.5, 28.8, and 36.6%, respectively. Higher age and longer disease duration were associated with frailty. Multivariable logistic regression analysis revealed that HAQ, DAS-28, and BDI-II scores were independently associated with frailty in RA patients.

CONCLUSION

Frailty is common, even among working-age RA patients. Physical function, disease activity, and depressive symptoms were independently associated with frailty. A multidisciplinary intervention approach, along with adequate pharmacological therapy, may promote successful aging in patients with RA.

The association of frailty with olfactory and gustatory dysfunction in older adults: a nationally representative sample

BACKGROUND

Olfaction and gustation are associated with age-related decline. Deficits in these chemosenses have been associated with significant comorbidities. Meanwhile, frailty, defined as a reduced physiological reserve, is well correlated with mortality and worse health outcomes. We sought to analyze a nationally representative patient population to determine the association between chemosensory dysfunction and frailty.

METHODS

Cross-sectional analysis of U.S. National Health and Nutrition Examination Survey (NHANES) 2013-2014 was performed, using multivariate logistic regression to examine the association between chemosensory dysfunction and frailty in adults aged ≥40 years (n = 3547). Self-reported olfactory dysfunction (sOD) and gustatory dysfunction (sGD), and measured olfactory dysfunction (mOD) and gustatory dysfunction (mGD) were assessed for all participants. Frailty was operationalized using a 39-item frailty index (FI) and stratified into 4 groups using validated cutoffs.

RESULTS

Participants with sOD and mOD had significantly higher mean FI scores (sOD: 0.18 vs 0.13, p < 0.001; mOD: 0.20 vs 0.14, p < 0.001), whereas subjects with sGD, but not mGD, had higher mean FI scores (sGD: 0.21 vs 0.13, p < 0.001; mGD: 0.14 vs 0.14, p = 0.953). Multivariate logistic regression demonstrated frail participants had significantly greater odds of sGD (odds ratio [OR] 4.11; 95% confidence interval [CI], 3.46 to 4.88), sOD (OR 2.35; 95% CI, 1.98 to 2.78), and mOD (OR 1.58; 95% CI, 1.22 to 2.05), but not mGD (OR 1.21; 95% CI, 0.91 to 1.61). This association was strongest in the frailest group.

CONCLUSION

Self-reported chemosensory dysfunction and mOD are independently associated with measures of frailty, suggesting a novel method to assess or predict frailty.

The use of Bayesian network models to identify factors related to frailty phenotype and health outcomes in middle-aged and older persons

BACKGROUND

Studies on frailty frequently only include older persons. The mapping of factors related to this syndrome and negative outcomes associated with it, also in middle age, may assist in health strategies to each age group.

OBJECTIVES

To investigate social and health factors related to the frailty phenotype and to analyze the probabilistic relationships between frailty, falls and hospitalization in middle-aged and older persons.

METHODS

This is a cross-sectional study using data for 4442 middle-aged (50-59 years) and older participants (60 years or older) from the Brazilian Longitudinal Study of Aging (ELSI-Brazil) 2015 and 2016. Bayesian network models were estimated with the score-based hill-climbing algorithm to identify factors associated with frailty, falls and hospitalization.

RESULTS

Mean age was 63.7 years, and prevalence of frailty was 8.5 % and 11.9 % among middle-aged and older participants, respectively. In the former, the probability of frailty increased when "poor" self-rated memory was considered in the model; and in the latter, the probability of frailty was greatest among individuals who did not participate socially and had the lowest level of education. In both age groups, frailty was an important factor that influenced the probability of negative health outcomes such as falls and hospitalization. However, this result depended on combinations of health factors in each sample.

CONCLUSIONS

This study has identified potential vulnerabilities that should be considered when undertaking a comprehensive assessment of middle-aged and older persons and developing suitable health strategies for each of these phases of life.

A Systematic Review of Frailty Trajectories: Their Shape And Influencing Factors

BACKGROUND AND OBJECTIVES

Frailty describes an increased vulnerability to adverse events such as disease or injury. Combatting this state remains a major challenge for geriatric research. By exploring how and why frailty changes throughout later life we will be better positioned to improve ways of identifying and treating those at high risk.

RESEARCH DESIGN AND METHODS

We systematically reviewed publications that captured rate of frailty progression over time and established any associated risk or protective factors that affected this progression. We included longitudinal observational studies which quantified frailty trajectories in adults aged 50+ using any validated continuous frailty measurement tool.

RESULTS

After screening 8,318 publications, 25 met our criteria. Findings show that despite a great degree of heterogeneity in the literature, progression of frailty is unquestionably affected by numerous risk and protective factors, with particular influence exhibited by social demographics, brain pathology, and physical co-morbidities.

DISCUSSION AND IMPLICATIONS

Findings that the gradient of frailty progression is affected by various influencing factors are valuable to clinicians and policymakers as will help identify those at highest frailty risk and inform prevention strategies. However, the heterogeneous methodological approaches of the publications included in this review highlights the need for consensus within the field to promote more coordinated research. Improved consistency of methods will enable further data synthesis and facilitate a greater understanding of the shape of frailty over time and the influencing factors contributing to change, the results of which could have crucial implications for frailty risk reduction.

Frailty Index as a clinical measure of biological age in psychiatry

BACKGROUND

Serious mental illnesses may be characterized by accelerated biological aging, and over the last years the research on the topic has been stimulated by studies exploring the molecular underpinnings of senescence.

METHODS

In the present manuscript we propose that measuring frailty, a general product of organismal ageing, through the "Frailty Index" (FI), a recently-emerged macroscopic indicator of functional status and biological age, adds an important marker to the measurements currently implemented in the study of accelerated biological age in psychiatric illnesses.

RESULTS

The FI quantifies functional negative health attributes and measures their cumulative effect, thus providing a useful estimate of the individual's biological age and risk profile. Recent studies in older adults have observed significant associations between FI and molecular measures of aging.

LIMITATIONS

High FI values can be driven by causes different from aging per se, so FI may be a sensitive but not specific measure of biological aging.

CONCLUSIONS

FI, which is extensively used in geriatrics and gerontology but it has rarely been used in relation to mental health, may be of relevance in the evaluation of age-related phenomena associated with psychiatric diseases.

Prevalence and risk factors associated with non-traffic related injury in the older population in Ghana: Wave 2 of the WHO Study on Global AGEing and adult health (SAGE)

Injuries are a significant cause of hospitalization in the older population, leading to a decline in physical activity and greater dependence on others. Compared to traffic related injury, relatively fewer studies have been conducted on non-traffic related injury in the older population in Ghana. This analysis provides a nationwide baseline prevalence and associated factors of non-traffic related injuries among older adults in Ghana. Data from the 2014-2015 nationally representative World Health Organization Study on global AGEing and adult health (SAGE) Ghana Wave 2 was used. A final sample of 3461 older adults living in 2827 households was used in the statistical modelling. Predictors of injury were examined using both single-level and multilevel binary logistic regression models. The prevalence of non-traffic related injury found in this study was 3.74%. The odds of being injured decreased among females (OR = 0.66, 95% CI: 0.46, 0.95) compared to their male counterparts and those who rated their heath state as moderate (OR = 0.59, 95% CI: 0.38, 0.94). Depression was the only risk factor identified in the multivariable model (OR = 2.55, 95%CI: 1.38, 4.71). The study did not observe significant residual household-level variation in injury status. The role of depression as a risk factor suggests that interventions that aim to reduce non-traffic related injury in older adults should consider improving mental health.

The course of depressive symptoms with decline in cognitive function - a longitudinal study of older adults receiving in-home care at baseline

Background

Depressive symptoms in old age are common, but the prevalence, persistence, and incidence of depressive symptoms in older adults with and without dementia receiving in-home care is less well studied, and descriptions of the relationship between severity of cognitive decline and depressive symptoms over time is, to our knowledge, lacking. The aim of the present study was to describe the prevalence, incidence and persistence of depressive symptoms over a 36-month follow-up period among older adults receiving in-home care at baseline, and to explore the association between cognitive function and the course of depressive symptoms over time.

Methods

In all, 1001 older people (≥ 70 years) receiving in-home care were included in a longitudinal study with three assessments over 36 months. Depressive symptoms were assessed using the Cornell Scale for Depression in Dementia. Clinical Dementia Rating Scale, diagnosis of dementia and mild cognitive impairment, general medical health, personal and instrumental activities of daily living, neuropsychiatric symptoms and the use of psychotropic medication were evaluated during the three assessments. Baseline demographic characteristics and information on nursing home residency at follow-up were recorded. Linear mixed models were estimated.

Results

The baseline prevalence and cumulative incidence of single depressive symptoms were higher in those with dementia at baseline than in those without dementia. The persistence of depressive symptoms did not differ between those with or without dementia at baseline. The severity of cognitive impairment and mean depressive symptom score assessed simultaneously were positively associated, but the strength of the association changed over time and was not significant at the last assessment. Furthermore, being younger, female, in very poor physical health, with neuropsychiatric symptoms and not becoming a nursing home resident were associated with more depressive symptoms when assessed simultaneously.

Conclusion

The baseline prevalence and cumulative incidence of depressive symptoms in those with and without dementia at baseline, as well as the relationship we found between the degree of cognitive decline and depressive symptoms over time show that depression and dementia are interconnected. Nurses and clinicians should pay attention to cognitive status when observing or evaluating depression among older adults receiving in-home care.

Comparing Changes and Transitions of Home Care Clients in Retirement Homes and Private Homes

Long-stay home care clients mostly reside in private homes or retirement homes, and the type of residence may influence risk factors for long-term care placement. This multi-state analytic study uses RAI-Home Care and administrative data from the Hamilton Niagara Haldimand Brant Local Health Integration Network to model conceptualized states of risk at baseline through a 13-month follow-up period. Modifiable risk factors in these states were client loneliness or depressive symptoms, and caregiver distress. A higher adjusted likelihood of being discharged deceased was found for the lowest-risk clients in retirement homes. Adjusting for client, service, and caregiver characteristics, retirement home residency was associated with higher likelihood of placement in a long-term care home; reduced caregiver distress; and increased client loneliness/depression. As an alternative to private home settings as the location for aging in place among these long-stay home care clients, retirement home residency represents some trade-offs between client and informal caregiver.

Suicide Among Older Adults Living in or Transitioning to Residential Long-term Care, 2003 to 2015

Importance

Almost 25% of Medicare beneficiaries live in residential long-term care (LTC) (eg, independent or assisted living facility or nursing home). There are few reliable statistics on completed suicide in LTC, in part because of data limitations.

Objectives

To estimate the number of suicides associated with residential LTC (ie, among persons in a facility, transitioning into or out of a facility, or otherwise associated with LTC) among adults 55 and older and, secondarily, to identify whether machine learning tools could improve the quality of suicide surveillance data.

Design, Setting, and Participants

Cross-sectional epidemiologic study (conducted in 2018) of restricted-access data from the National Violent Death Reporting System (NVDRS) (2003-2015) using restricted-access case narratives from suicides and undetermined deaths among adults 55 years and older in 27 states. Participants were all suicides and undetermined deaths (N = 47 759) among persons 55 years and older.

Exposure

Long-term care cited in the coroner/medical examiner case narrative, whether as a reason for self-harm or the injury location, identified using machine learning natural language processing (NLP) algorithms plus manual review of texts.

Main Outcomes and Measures

Number and characteristics (eg, demographics, health history, and means of injury) of suicides associated with LTC. The κ statistic was used to estimate the reliability of the existing NVDRS injury location codes relative to cases identified by the algorithm.

Results

Among 47 759 persons 55 years and older (median age, 64 years; 77.6% male; 90.0% non-Hispanic white), this study identified 1037 suicide deaths associated with LTC, including 428 among older adults living in LTC, 449 among older adults transitioning to LTC, and 160 otherwise associated with LTC. In contrast, there were only 263 cases coded with the existing NVDRS location code "supervised residential facility," which had poor agreement with cases that the algorithm identified as occurring in LTC (κ statistic, 0.30; 95% CI, 0.26-0.35).

Conclusions and Relevance

Over a 13-year period, approximately 2.2% of suicides among adults 55 years and older were associated with LTC in some manner. Clinicians, administrators, and policy makers should consider ways to promote the mental health and well-being of older adults experiencing functioning limitations and their families. Natural language processing may be a useful way to improve abstraction of variables in the NVDRS.

Prevalence of frailty and its association with depressive symptoms among older adults in Singapore

OBJECTIVES

The aims of the study were to (1) estimate the prevalence of frailty among community-dwelling older adults , and (2) investigate the independent association between level of frailty and depressive symptoms.

METHODS

A total of 721 older adults (aged 60 and above ) were included in this study. Severity of frailty was determined using the Clinical Frailty Scale and further classified into four levels (CFS1-3: F1, CFS4: F2, CFS5: F3, and CFS6-7: F4). The depressive symptoms were assessed using the Patient Health Questionnaire-9. The prevalence of frailty by four levels was described and the association between level of frailty and depressive symptoms was assessed using multiple linear regression.

RESULTS

The prevalence of frailty among the study population was 24.5% (F2: 14.4%, F3:3.7%, F4: 6.4%). There was no significant difference in level of frailty between male and female. With the increase in severity level of frailty, older adults reported substantially higher depressive symptom scores (p < .001), even after controlling for socio-demographics, number of non-mental chronic conditions, and number of medications taken regularly.

CONCLUSIONS

Level of frailty is independently associated with depressive symptoms among community-dwelling older population, which is not fully explained by symptom overlap, socio-demographic, and comorbidity covariates.

Frailty as a Predictor of All-Cause Mortality Among Older Nursing Home Residents: A Systematic Review and Meta-analysis

OBJECTIVES

We performed a meta-analysis based on prospective cohort studies to synthesize the pooled risk effect and to determine whether frailty is a predictor of all-cause mortality.

DESIGN

Systematic review and meta-analysis.

SETTING

PubMed, EMBASE, and the Cochrane Library were systematically searched in October 2018. A random effects model was applied to combine the results according to the heterogeneity of the included studies.

PARTICIPANTS

Older nursing home residents.

MEASUREMENTS

Mortality risk due to frailty.

RESULTS

Fourteen studies (9076 participants) were included in this meta-analysis. Pooled results demonstrated that nursing home residents with frailty were at an increased risk of mortality [pooled hazards ratio (HR) = 1.88, 95% confidence interval (CI) = 1.57, 2.25, I² = 47.8%, P < .001] compared to those without frailty. Results of subgroup analyses showed that frailty was significantly associated with the risk of mortality among older nursing home residents when using FRAIL-NH (pooled HR = 2.10, 95% CI = 1.60-2.77, P < .001) and Frailty Index (pooled HR = 1.74, 95% CI = 1.40-2.18, P < .001) to define frail people, whereas when using the diagnosis criteria of CSHA-CFS for frailty, the pooled HR was 2.82 (95% CI = 0.79-10.10, P = .111). In addition, the subgroup analysis for length of follow-up showed that studies with a follow-up period of 1 year or more (pooled HR = 1.83, 95% CI = 1.52, 2.21, P < .001) reported a significantly higher rate of mortality among individuals with frailty, compared to those without frailty. Similar results were also found in studies with a follow-up period of less than 1 year (pooled HR = 2.67, 95% CI = 1.43, 5.00, P = .002).

CONCLUSIONS AND IMPLICATIONS

Frailty is a significant predictor of all-cause mortality in older nursing home residents. Therefore, there is an urgent need to screen for frailty in nursing home residents and carry out appropriate multidisciplinary intervention strategies to prevent poor outcomes and reduce the rate of mortality among older nursing home residents.

Multicomponent Frailty Assessment Tools for Older People with Psychiatric Disorders: A Systematic Review

OBJECTIVE

To review evidence evaluating the use of multicomponent frailty assessment tools in assessing frailty in older adults with psychiatric disorders.

METHODS

A systematic literature review was conducted to identify all multicomponent frailty assessment tools (ie, a tool that assesses two or more indicators of frailty). The items of each frailty assessment tool were compared with Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) diagnostic criteria for psychiatric disorders to assess construct overlap. Studies conducted in community, inpatient, and outpatient clinical settings were considered for inclusion.

PARTICIPANTS

Adults aged 60 years or older.

RESULTS

A total of 5639 records were identified following the removal of duplicates, from which 95 studies were included for review. Of the 48 multicomponent frailty assessment tools identified, no tool had been developed for, or validated in, older adult populations with a psychiatric disorder. Overall, 20 of 48 frailty assessment tools contained a psychological assessment domain, with 17 of 48 tools citing the presence of depressed mood and/or anxiety as a frailty indicator. Common areas of construct overlap in frailty assessment tools and DSM-5 diagnostic criteria included weight loss (29 of 48) and fatigue (21 of 48).

CONCLUSIONS

Significant construct overlap exists between the indicators of frailty as conceptualized in existing frailty assessment tools and DSM-5 diagnostic criteria for common psychiatric disorders including major depressive episode and generalized anxiety disorder that has the potential to confound frailty assessment results. Further research is necessary to establish a reliable and valid tool to assess frailty in this population. J Am Geriatr Soc 67:1085-1095, 2019.

Burden of Depressive Symptoms Over 2 Decades and Risk of Nursing Home Placement in Older Women

OBJECTIVES

To determine the association between cumulative burden of depressive symptoms and risk of nursing home (NH) placement over 2 decades.

DESIGN

Prospective cohort study with data linked to Medicare claims files.

SETTING

Clinic sites in Baltimore, Maryland; Minneapolis, Minnesota; and the Monongahela Valley near Pittsburgh, Pennsylvania.

PARTICIPANTS

Initially community-dwelling women aged 65 and older (N=3,646).

MEASUREMENTS

Depressive symptom burden was determined using the Geriatric Depression Scale measured over 18 years to calculate accumulation of burden. NH placement was determined using Medicare claims data.

RESULTS

In Fine-Gray proportional hazards analyses including demographic characteristics, medical comorbidities, functional impairment, and recent depression exposure and accounting for competing risk of death, women with low depressive symptom burden were twice as likely to experience NH placement as those with minimal burden (hazard ratio (HR) = 1.92, 95% confidence interval (CI) = 1.16-3.20), women with moderate burden were more than twice as likely (HR = 2.62, 95% CI = 1.59-4.31), and women with high burden (HR = 3.08, 95% CI = 1.87-5.08) were three times as likely. The addition of antidepressant use to this model attenuated the risk only slightly.

CONCLUSION

In older women, cumulative burden of depressive symptoms over nearly 2 decades is associated with greater risk of transitioning from community-living to a NH irrespective of recent depression exposure, medical comorbidities, functional impairment, and the competing risk of death. This work supports the need for improving recognition, monitoring, and treatment of depressive symptoms early, which may reduce or delay NH placement.

Distress Tolerance Intervention for Improving Self-Management of Chronic Conditions: A Systematic Review

BACKGROUND

The inability to tolerate distress can negatively influence effective self-management (SM) of chronic conditions by interfering with the ability to focus on illness needs and impairing problem-solving and prioritizing capabilities, as well as engagement in SM activities. Interventions to increase distress tolerance offer a holistic approach to chronic disease SM and may enhance the individual's ability to apply SM skills and resources to improve quality of life and overall health. The purpose of this systematic review was to deepen understanding of the relationships among distress tolerance and goal-oriented problem-solving as an aspect of chronic disease SM.

METHOD

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations were used to develop a search strategy, selection criteria, screening, and identification and extraction procedures. PubMed, CINAHL, PsychInfo, and Scopus were searched from 2006 to December 2017 using the following search terms: distress tolerance, chronic conditions, self-management.

RESULTS

Across the 11 studies included in the literature review, there was a high level of heterogeneity in the use of subjective and objective measures to assess distress tolerance, and only one study included instruments to measure goal-oriented problem-solving, the target of distress tolerance interventions that are assumed to influence the selected health outcome.

CONCLUSION

Further research is needed on the efficacy of distress tolerance interventions for improving SM of chronic conditions. Theory-driven interventions that explicate the precise goal-oriented problem-solving and SM behaviors that are expected to change as a result of the distress tolerance intervention will provide insight on the efficacy of the intervention and help close the theory-practice gap.
