Social support and long-term mortality in the elderly: Role of comorbidity

The association between frailty, care receipt and unmet need for care with the risk of hospital admissions

BACKGROUND

Frailty is characterised by a decline in physical, cognitive, energy, and health reserves and is linked to greater functional dependency and higher social care utilisation. However, the relationship between receiving care, or receiving insufficient care among older people with different frailty status and the risk of unplanned admission to hospital for any cause, or the risk of falls and fractures remains unclear.

METHODS AND FINDINGS

This study used information from 7,656 adults aged 60 and older participating in the English Longitudinal Study of Ageing (ELSA) waves 6-8. Care status was assessed through received care and self-reported unmet care needs, while frailty was measured using a frailty index. Competing-risk regression analysis was used (with death as a potential competing risk), adjusted for demographic and socioeconomic confounders. Around a quarter of the participants received care, of which approximately 60% received low levels of care, while the rest had high levels of care. Older people who received low and high levels of care had a higher risk of unplanned admission independent of frailty status. Unmet need for care was not significantly associated with an increased risk of unplanned admission compared to those receiving no care. Older people in receipt of care had an increased risk of hospitalisation due to falls but not fractures, compared to those who received no care after adjustment for covariates, including frailty status.

CONCLUSIONS

Care receipt increases the risk of hospitalisation substantially, suggesting this is a group worthy of prevention intervention focus.

Social support and the burden of physical and psychiatric comorbidities in the patients with late-onset epilepsy in China: A cross-sectional study

INTRODUCTION

Epilepsy is the third most common neurological disorder in elderly people. Patients with epilepsy (PWEs) are more likely to have comorbidities. Social support is very important for PWEs. However, there are many gaps in the research on social support in older PWEs, especially the correlation between social support and comorbidities.

METHODS

A cross-sectional study was conducted in three hospitals in China. Social support was assessed using the Social Support Rate Scale. The burden of physical comorbidities was assessed using the CCI, and global disability was assessed using the mRS. The NDDIE was used to assess depression, the GAD7 was used for anxiety, the CDR was used for cognitive status, and the NPI was used for psychotic symptoms.

RESULTS

A total of 154 older PWEs participated in the study. There were 97 patients with at least one physical comorbidities. The burden of physical comorbidities was negatively correlated with overall social support (Adj. r = -0.35, P < 0.001) and global disability (Adj. r = -0.45, P < 0.001). In terms of psychiatric comorbidities, anxiety, depression, and cognitive status were not correlated with overall social support (Adj. r = -0.03, -0.02, and -0.11, P > 0.05). Psychotic symptoms were correlated with overall social support (Adj. r = -0.20, P < 0.05). The overall burden of psychiatric comorbidities was associated with overall social support (r = 0.30, P < 0.01).

DISCUSSION

Neurologists and social workers should consider more personalized biopsychosocial care to improve the quality of life of older PWEs.

Impact of Cohabitation during Confinement on Older Adults' Negative Affect: What Specificity of Life as a Couple?

BACKGROUND

Social isolation is a risk factor for older adults' physical and psychological health. The beneficial effect of social connections in times of major health events is undeniable. Nevertheless, it remains unclear whether the positive effect of social support depends on the relationship type.

OBJECTIVES

This study aimed to investigate the influence of older adults' living conditions on the risk of experiencing negative affect during the first lockdown and post-lockdown.

DESIGN

An epidemiological study conducted during the COVID-19 crisis, at the time of the first lockdown, and 2 to 3 months following the lockdown.

SETTING

A subset sample of the PACOVID survey, a population-based survey of older adults.

PARTICIPANTS

Altogether, 277 participants were included into three groups depending on their living conditions: Group 1 "living alone" (n = 141); Group 2 "living with their spouse" (n = 106); Group 3 "living in cohabitation with relatives" (n = 30).

MEASUREMENTS

Mixed logistic regression analyses were used to study the change in the risk of experiencing negative affects over time according to the living conditions. The presence of negative affects during lockdown was assessed using three items from the 20-item Center for Epidemiologic Studies Depression Scale : «Do you feel sad?»; «Do you feel depressed?; «Do you feel lonely?

RESULTS

Participants living with their relatives or partner were significantly less likely to experience negative affect than those living alone during lockdown. Moreover, over time, only those living with their spouse had this lesser risk compared to those living alone.

CONCLUSIONS

These findings highlight the protective effect of social support over time and more specifically of that provided by the spouse. Couple functioning ought to be given consideration when studying the impact of health crisis situation on the mental health of older adults.

Gender Interaction in Association of Perceived Social Support and Health-Related Quality of Life Among Iranian Older People: A Cross-sectional Survey

Background: The purpose of this study was to examine the relationship between perceived social support (PSS) and dimensions of health-related quality of life (HRQoL) and to examine possible gender interaction in the mentioned associations. Methods: A community-based cross-sectional study conducted among 644 participants over the age of 60 years old in Tehran. The data were collected through face-to-face interviews conducted in their own homes, by using a structured multi-sectional questionnaire. The version 1 of the SF-12 scale was used to measure the HRQoL, consisting of two summary measures; PCS (Physical Component Score) and MCS (Mental Component Score). The Persian version of the Social Provisions Scale (SPS) was used to measure PSS. Four multilevel mixed-effects logistic regression models were used to examine the associations. Results: Older people with poor SPS score were 1.8 times more likely to be in the worst quartile of the MCS distribution (CI=1.11-2.93, P =0.021), and twice as likely to be in the worst quartile of the PCS distribution (CI=1.18-3.54, P =0.011). We found strong evidence to support the hypothesis of gender interaction in the association between economic status and PCS [Men: OR 0.28, CI (0.11-0.71); Women: OR 1.00, CI (0.53-1.88); P of Interaction 0.021], and a borderline evidence for gender interaction in the association between physical activity and PCS [Men: OR 5.32, CI (2.14-13.20); Women: OR 1.80, CI (0.82-3.93); P of Interaction 0.051]. Conclusions: Social support could be regarded as one of the main social determinants affecting HRQoL among older people. Men with poor economic status and poor physical activity, compared to women, are more likely to suffer from poor quality of life, thus men should be prioritized in financial support and life style and physical activity interventions.

The moderating effects of social support and depressive symptoms on pain among elderly multimorbid patients-data from the multicentre, prospective, observational cohort study MultiCare

OBJECTIVES

Depressive symptoms and chronic pain are common among patients with multimorbidity creating a complex medical condition for both the patient and the general practitioner. Perceived social support may function as a protective measure.

To examine the impact of perceived social support as a potential moderator between depressive symptoms and pain intensity and pain disability in daily activities in multimorbid patients aged 75+.

METHOD

Data from 3,189 patients of the German longitudinal cohort study MultiCare were obtained at baseline and follow-ups during 5 years. Multilevel linear mixed-effects analyses were conducted for pain intensity (model 1) and pain disability in daily activities (model 2). The interaction term social support by depression score was included to test for moderation.

RESULTS

The interaction between social support and depressive symptoms was significantly associated with the pain intensity score 0.41 (SE=.17; 95-CI[.08;.74]) but not with the pain disability score 0.35 (SE=.19; 95-CI[-.01;.72]). Additionally, men and individuals with medium or higher educational level showed reduced pain intensity and disability scores. Pain disability scores increased with age and depressive symptoms. Increased pain scores were also found for body mass index and burden of multimorbidity.

CONCLUSION

Perceived social support amplified the association of depressive symptoms on pain intensity and did not show a protective function. The high scores of perceived social support among the participants may point to the practice of secondary gain due to the patients immense health burden.

[Frailty syndrome as an independent predictor of adverse prognosis in patients with chronic heart failure]

This review presents results of clinical studies of senile asthenia ("fragility") syndrome and chronic heart failure (CHF). Recent reports of the "fragility" prevalence in patients with CHF are described. The review presents specific features of pathophysiological pathways underlying the development of both senile asthenia syndrome and CHF; the role of "fragility" in the progression and complications of CHF is addressed. Senile asthenia syndrome associated with CHF is regarded as an independent predictor of unfavorable prognosis and high mortality in this patient category. The authors concluded that methods for "fragility" evaluation in CHF patients followed by risk stratification and selection of individual management tactics should be implemented in clinical practice.

Social support and outcomes in older adults with lung cancer

BACKGROUND

Insufficient social support is associated with increased mortality among older adults. Lung cancer is primarily a disease of older adults and is the leading cause of all cancer deaths. We assessed the association of social support with outcomes among older adults with lung cancer.

MATERIALS AND METHODS

Adults age 65 and older with lung cancer with a completed geriatric assessment (GA) were assessed. Emotional social support (ES) and tangible (material, instrumental) support (TS) measures and patient characteristics were obtained from the GA. The electronic health record was used to extract clinical variables. Simple linear regression models evaluated the association between social support scales with patient and clinical factors.

RESULTS

79 adults were assessed. White race was positively associated with ES score (p=.04), while higher BMI (p=.03), depression (p=.03) and anxiety (p=.02) were associated with worse ES. Higher BMI was associated with higher/better TS score (p=.02) while living alone was associated with lower/worse TS score (p=.03). Completion of platinum-based doublet chemotherapy with immunotherapy as planned was associated with higher ES scores (p=.02) and higher TS scores (p=.02). Disease progression was associated with lower ES scores (p=.03).

CONCLUSION

Social support may influence clinical outcomes in older adults with lung cancer. As lung cancer often portends to poor prognosis, social support may be an important prognostic indicator.

Hematopoietic progenitor cell liabilities and alarmins S100A8/A9-related inflammaging associate with frailty and predict poor cardiovascular outcomes in older adults

Frailty affects the physical, cognitive, and social domains exposing older adults to an increased risk of cardiovascular disease and death. The mechanisms linking frailty and cardiovascular outcomes are mostly unknown. Here, we studied the association of abundance (flow cytometry) and gene expression profile (RNAseq) of stem/progenitor cells (HSPCs) and molecular markers of inflammaging (ELISA) with the cardiorespiratory phenotype and prospective adverse events of individuals classified according to levels of frailty. Two cohorts of older adults were enrolled in the study. In a cohort of pre-frail 35 individuals (average age: 75 years), a physical frailty score above the median identified subjects with initial alterations in cardiorespiratory function. RNA sequencing revealed S100A8/A9 upregulation in HSPCs from the bone marrow (>10-fold) and peripheral blood (>200-fold) of individuals with greater physical frailty. Moreover higher frailty was associated with increased alarmins S100A8/A9 and inflammatory cytokines in peripheral blood. We then studied a cohort of 104 more frail individuals (average age: 81 years) with multidomain health deficits. Reduced levels of circulating HSPCs and increased S100A8/A9 concentrations were independently associated with the frailty index. Remarkably, low HSPCs and high S100A8/A9 simultaneously predicted major adverse cardiovascular events at 1-year follow-up after adjustment for age and frailty index. In conclusion, inflammaging characterized by alarmin and pro-inflammatory cytokines in pre-frail individuals is mirrored by the pauperization of HSPCs in frail older people with comorbidities. S100A8/A9 is upregulated within HSPCs, identifying a phenotype that associates with poor cardiovascular outcomes.

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.

Cognitive reappraisal and the association between depressive symptoms and perceived social support among older adults

OBJECTIVES

There is an association between depression and diminished social support; indeed, interpersonal dysfunction is often a central feature of depression. The purpose of this study is to examine the role that an emotion regulation (ER) strategy, cognitive reappraisal, plays in influencing the association between depressive symptoms and perceived social support in older adults.

METHOD

Data for this cross-sectional study come from a community-based survey of older adults (60+, N = 910). We examined the effects of depressive symptoms and cognitive reappraisal on perceived social support. We then examined the potential moderating role of cognitive reappraisal on the association between depressive symptoms and perceived social support.

RESULTS

Depressive symptoms were associated with lower levels of perceived social support. Cognitive reappraisal was associated with higher levels of perceived social support. Cognitive reappraisal moderated the negative consequences of depressive symptoms on perceived social support. Whereas depressive symptoms had a negative effect on perceived social support, the negative effect was greater for those with lower levels of cognitive reappraisal compared to those with higher levels of cognitive reappraisal.

DISCUSSION

ER strategies may play a role in attenuating the negative consequences of depressive symptoms on social support in older age. It may be possible to help individuals maintain social support in later life, even in the face of mental health challenges, if they cultivate ER skills.

Validation of "(fr)AGILE": a quick tool to identify multidimensional frailty in the elderly

Background

Several tools have been proposed and validated to operationally define frailty. Recently, the Italian Frailty index (IFi), an Italian modified version of Frailty index, has been validated but its use in clinical practice is limited by long time of administration. Therefore, the aim of this study was to create and validate a quick version of the IFi (AGILE).

Methods

Validation study was performed by administering IFi and AGILE, after a Comprehensive Geriatric Assessment (CGA) in 401 subjects aged 65 or over (77 ± 7 years). AGILE was a 10-items tool created starting from the more predictive items of the four domains of frailty investigated by IFi (mental, physical, socioeconomic and nutritional). AGILE scores were stratified in light, moderate and severe frailty. At 24 months of follow-up, death, disability (taking into account an increase in ADL lost ≥1 from the baseline) and hospitalization were considered. Area under curve (AUC) was evaluated for both IFi and AGILE.

Results

Administration time was 9.5 ± 3.8 min for IFi administered after a CGA, and 2.4 ± 1.2 min for AGILE, regardless of CGA (p < 0.001). With increasing degree of frailty, prevalence of mortality increased progressively from 6.5 to 41.8% and from 9.0 to 33.3%, disability from 16.1 to 64.2% and from 22.1 to 59.8% and hospitalization from 17.2 to 58.7% and from 27.0 to 52.2% with AGILE and IFi, respectively (p = NS). Relative Risk for each unit of increase in AGILE was 56, 44 and 24% for mortality, disability and hospitalization, respectively and was lower for IFi (8, 7 and 4% for mortality, disability and hospitalization, respectively). The AUC was higher in AGILE vs. IFi for mortality (0.729 vs. 0.698), disability (0.715 vs. 0.682) and hospitalization (0.645 vs. 0.630).

Conclusions

Our study shows that AGILE is a rapid and effective tool for screening multidimensional frailty, able to predict mortality, disability and hospitalization, especially useful in care settings that require reliable assessment instruments with short administration time.

Multimorbidity and functional limitation: the role of social relationships

OBJECTIVES

To examine the relationship between multimorbidity and functional limitation, and how social relationships alter that association.

METHODS

This cross-sectional study used data collected by self-reported questionnaires from adults aged 65 years and older living in a rural area in Japan in 2017. This analysis included complete data from 570 residents. Multimorbidity status was defined as having two chronic diseases exist simultaneously in one individual, and the function status was measured by their long-term care needs. Social relationships were assessed by the Index of Social Interaction and divided into high and low levels. Multiple logistic regression analysis was used to examine the association between social relationships and functional limitation and to assess the role of social relationships in this association.

RESULTS

The logistic regression model indicated that the risk of functional limitation was higher in multimorbidity participants than free-of-multimorbidity participants (OR = 2.55, 95% CI = 1.56-4.16). Compared with participants with no multimorbidity and a high level of social relationships, low level of social relationships increased the risk of functional limitation among participants both with and without multimorbidity, with the OR = 7.71, 95% CI = 3.03-19.69 and OR = 3.28, 95% CI = 1.30-8.27, respectively. However, no significant result was found in participants with multimorbidity and a high level of social relationships (P = 0.365).

CONCLUSIONS

Multimorbidity was associated with functional limitations. However, this association could be increased by a low level of social relationships and decreased by a high level of social relationships.

Physical Comorbidity and Health Literacy Mediate the Relationship Between Social Support and Depression Among Patients With Hypertension

Depression is a common comorbidity among patients with hypertension. Patients with hypertension and depression have worse health outcomes compared to those without depression. The combined effects of social support, physical comorbidity, and health literacy on depression among individuals with hypertension remain unclear. A survey was conducted between December 2017 and May 2018 to investigate the relationships among social support, physical comorbidity, health literacy, and depression in a population of patients with hypertension in rural areas of Sichuan province, China. Multiple linear regression was used to examine factors that influenced depression, and structural equation modeling (SEM) was used to examine the relationships among the four study variables. The mean scores of 549 patients with hypertension were 37.17 ± 6.84 for social support, 14.62 ± 6.26 for health literacy, and 3.56 ± 3.05 for depression; furthermore, 34.2% of participants had physical comorbidity. Gender and per capita annual family income were significantly associated with depression. Physical comorbidity was directly positively related to depression while health literacy was directly negatively related to depression. Social support had an indirect negative association with depression by the mediating effects of health literacy and physical comorbidity. Adequate social support and health literacy, and less physical comorbidity could potentially contribute to reducing depression. The study highlights the importance of social support in maintaining mental health among patients with hypertension. Strategies that target the enhancement of social support and health literacy should be prioritized to relieve depression among patients with hypertension. More attention should be paid to women, low-income individuals, and patients with physical comorbidities.

Traumatic Stress, Social Support, and Health Among Older American Indians: The Native Elder Care Study

OBJECTIVES

To estimate the prevalence of lifetime traumatic experiences, describe related symptoms of traumatic stress, and examine their association with perceived social support and physical and mental health among older American Indians.

METHOD

Analyses of existing interview data from the Native Elder Care Study, a random age-stratified sample of 505 tribal members ≥55 years of age conducted in partnership with a large Southeastern tribe. Interviews assessed trauma exposure, traumatic stress, measures of social support, and physical and mental health status.

RESULTS

Overall, 31% of participants had experienced a traumatic event; of these, 43% reported traumatic stress at the time of the interview. Higher perceived social support was associated with a reduced prevalence of traumatic stress. Compared to their counterparts without traumatic stress, women participants reporting traumatic stress reported more symptoms of depression, and both symptomatic men and women had a higher prevalence of cardiovascular disease and chronic pain.

DISCUSSION

Traumatic stress was associated with less perceived social support and poorer health. Social support was not found to moderate the relationship between traumatic stress and physical and mental health.

Physical vs. multidimensional frailty in older adults with and without heart failure

Aims

The assessment of frailty in older adults with heart failure (HF) is still debated. Here, we compare the predictive role and the diagnostic accuracy of physical vs. multidimensional frailty assessment on mortality, disability, and hospitalization in older adults with and without HF.

Methods and results

A total of 1077 elderly (≥65 years) outpatients were evaluated with the physical (phy‐Fi) and multidimensional (m‐Fi) frailty scores and according to the presence or the absence of HF. Mortality, disability, and hospitalizations were assessed at baseline and after a 24 month follow‐up. Cox regression analysis demonstrated that, compared with phy‐Fi score, m‐Fi score was more predictive of mortality [hazard ratio (HR) = 1.05 vs. 0.66], disability (HR = 1.02 vs. 0.89), and hospitalization (HR = 1.03 vs. 0.96) in the absence and even more in the presence of HF (HR = 1.11 vs. 0.63, 1.06 vs. 0.98, and 1.14 vs. 1.03, respectively). The area under the curve indicated a better diagnostic accuracy with m‐Fi score than with phy‐Fi score for mortality, disability, and hospitalizations, both in absence (0.782 vs. 0.649, 0.763 vs. 0.695, and 0.732 vs. 0.666, respectively) and in presence of HF (0.824 vs. 0.625, 0.886 vs. 0.793, and 0.812 vs. 0.688, respectively).

Conclusions

The m‐Fi score is able to predict mortality, disability, and hospitalizations better than the phy‐Fi score, not only in absence but also in presence of HF. Our data also demonstrate that the m‐Fi score has better diagnostic accuracy than the phy‐Fi score. Thus, the use of the m‐FI score should be considered for the assessment of frailty in older HF adults.

Association of social support and antepartum depression among pregnant women

BACKGROUND

Few investigators have evaluated the association between early pregnancy social support and depression; however, increased social support may improve mental health during pregnancy. Our objective is to examine whether in early pregnancy there is an association between social support and maternal depression among women in Peru.

METHODS

2,062 pregnant women participated in structured interviews. Early pregnancy social support was measured using the Social Support Questionnaire (SSQ-6). We evaluated the number of individuals that participants could turn to in different situations (Social Support Number Score; SSQN) and their satisfaction with support received (Social Support Satisfaction Score; SSQS). Median SSQN and SSQS characterized participants according to high and low levels of support. SSQN family vs. non-family support were also evaluated separately. Antepartum depression was assessed using the Patient Health Questionnaire-9. Multivariable logistic regression procedures were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs).

RESULTS

39.6% of women reported high SSQN and 45.5% reported high SSQS. Approximately 25% had antepartum depression. Women with high SSQN had 22% lower odds of antepartum depression (OR = 0.78; 95%CI: 0.63-0.97). Similarly, women with high SSQS scores had 45% lower odds of antepartum depression (OR = 0.55; 95%CI: 0.45-0.68). Women with high SSQN non-family scores had 30% lower odds antepartum depression compared to those with low SSQN non-family scores (OR = 0.70; 95%CI: 0.57-0.86). The association between SSQN family scores and antepartum depression did not reach statistical significance.

CONCLUSION

Increased social support may improve maternal mental health during pregnancy and this association should be assessed in longitudinal studies.

General thoughts of death and mortality: findings from the Komo-Ise cohort, Japan

AIMS

Death ideation (thinking about/wishing for one's own death, thinking that one would be better off dead) is linked to an increased mortality risk. However, comparatively little is known about more general thoughts of death (GTOD) where no wish to die or life value is expressed. This study examined whether GTOD predicted mortality in a community-based cohort of older adults.

METHODS

Data came from the Komo-Ise cohort study in Gunma prefecture, Japan. The analytic sample comprised 8208 individuals (average age 61.3 (range 47-77)) who were asked in wave 2 of the study in 2000 if they had 'Thought about death more than usual, either your own, someone else's or death in general?' in the past 2 weeks. Death data were obtained from the municipal resident registration file. Cox proportional hazards regression analysis was used to examine associations.

RESULTS

During the follow-up period (2000-2008), there were 672 deaths. In a model adjusted for baseline covariates, GTOD were significantly associated with all-cause mortality (hazards ratio 1.66, 95% confidence interval 1.20-2.29). Stratified analyses showed an association between GTOD and mortality in men, older subjects (⩾70 years), married individuals and those with higher social support.

CONCLUSIONS

GTOD are associated with an increased mortality risk among older citizens in Japan. Research is now needed to determine the factors underlying this association and assess the clinical relevance of screening for GTOD in older individuals.

Negative affectivity and social inhibition are associated with increased cardiac readmission in patients with heart failure: A preliminary observation study

Background

Type D personality was hypothesized to influence clinical and patient-centered outcomes patients with heart failure. The aim of this study was to investigate the association between negative affectivity and social inhibition components of Type D personality and cardiac readmission in patients with heart failure.

Methods

A prospective observational study design was used. A total of 222 patients with heart failure were recruited from the department of cardiology in two regional hospitals in Taiwan. The 14-item Type D Scale-Taiwanese version was used to assess negative affectivity and social inhibition of the patients. Logistic regression analyses were conducted to determine the association of both Z-score transformed and dichotomized negative affectivity and social inhibition with 6-month and 18-month cardiac readmissions.

Results

A total of 55 patients (24.8%) and 89 patients (40.1%) had cardiac readmissions within 6 months and 18 months, respectively. Multiple logistic regression analyses of Z-score transformed negative affectivity and social inhibition were significantly associated with (1) 6-month cardiac readmission with odds ratios of 1.62 (P = 0.003) and 1.48 (P = 0.014), respectively and (2) 18-month cardiac readmission with odds ratios of 1.45 (P = 0.013) and 1.38 (P = 0.031), respectively. Similar findings were obtained when negative affectivity and social inhibition were analyzed as dichotomized scores.

Conclusions

Negative affectivity and social inhibition components of the Type D personality were significantly associated with a higher risk of cardiac readmission in both 6 months and 18 months after the initial hospitalization in patients with heart failure.

Effects of receiving and providing family support on mortality in non-frail, pre-frail and frail older adults in Taiwan: a 12-year follow-up longitudinal study

BACKGROUND

To investigate the association between providing or receiving family support and risk of mortality in non-frail, pre-frail and frail older people.

METHODS

Data were obtained from Taiwan's Longitudinal Study on Aging (TLSA) from 1996 to 2007 for 2186 people (1207 males; 979 females) aged ≥ 67 years at the time of 1996 follow-up survey. These older adults were categorized as being non-frail (normal), pre-frail, and frail, with frailty defined as the presence of three or more of the following criteria: shrinking, weakness, exhaustion, slowness, and low physical activity. Cox regression analysis was used to examine the association between the people's providing family support or their receiving family support on mortality, after adjustment for several demographic and health status covariates.

RESULTS

The participants (55.9% male) had an average age of 73.8 (SD 5.5) years. In total, 886 (40.5%) were classified as non-frail, 886 (40.5%) as pre-frail and 414 (19.9%) as frail. Multivariate Cox regression analysis revealed a significant association between providing family support and lower mortality rates in the non-frail older adults (hazard ratio 0.913; 95% confidence interval 0.855-0.975; p = 0.0063). This association was also significant in the younger (67-74 years old) pre-frail males but not females after adjustment. No significant association was found between receiving family support and mortality risk regardless of the frailty status, age, or gender.

CONCLUSIONS

Providing family support to others may prolong life expectancy of the pre-frail older adults.

Association of providing/receiving support on the mortality of older adults with different living arrangements in Taiwan: a longitudinal study on ageing

This longitudinal study evaluated the direct effects of providing/receiving family support on mortality in older adults with different living arrangements in Taiwan. All data analysed were obtained from the Taiwan Longitudinal Study on Aging, 1996–2007, of residents aged ⩾67 years (1,492 men and 1,177 women) and Taiwan's National Death Register. Living arrangements were divided into living alone, living only with spouse, living with family and living with others. Support was mainly defined as family support divided into two categories: providing and receiving. The effect of providing/receiving family support on the mortality of older adults was evaluated using Cox regression analysed by living arrangement. Participants living with their families had lower educational levels (illiterate or elementary school) and more disability in both activities of daily living and instrumental activities of daily living. However, they provided more family support than those in other living arrangements. After adjusting for several potentially confounding variables, including background characteristics, economic status and various health status measures, results showed that older adults living with their families and providing support had an 11 per cent lower mortality rate (Hazard ratio = 0.89; 95 per cent confidence interval = 0.83–0.96; p = 0.0018). In conclusion, we found that, when living with family, the lives of older adults can be extended by providing support, clearly supporting the old adage ‘it is more blessing to give than to receive’. Older adults wanting to extend their lives can be encouraged to provide more help to their families.

Construct validity and factor structure of a Spanish-language Social Support Questionnaire during early pregnancy

Background

The Social Support Questionnaire – Short Form (SSQ-6) is a widely used instrument that assesses availability and satisfaction of a person’s social support. The present study aimed to evaluate the construct validity and factor structure of the Spanish language version of the SSQ-6 during early pregnancy.

Participants and methods

A total of 4,236 pregnant Peruvian women were interviewed at 10.3 ± 3.8 weeks of gestation. In-person interviewers were used to collect lifestyle, demographic, and social support characteristics. The construct validity and factorial structure of the SSQ-6 were assessed through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The internal consistency was evaluated using Cronbach’s alpha.

Results

The mean SSQ-6 score was 39.6 ± 6.8 and Cronbach’s alpha was 0.83. EFA resulted in a three-factor solution that accounted for 60.6% of the variance. CFA results confirmed the three-factor structure and yielded measures indicating goodness of fit (comparative fit index of 0.9401) and accuracy (root mean square error of approximation of 0.0394).

Conclusion

Although the SSQ-6 was originally developed as a two-factor model, and previous studies have supported this, in our study a three-factor model was found to be more appropriate. The SSQ-6 was found to have good construct validity and reliability for assessing social support.

Orthostatic Hypotension in the Elderly: A Marker of Clinical Frailty?

BACKGROUND

Orthostatic hypotension (OH) has high prevalence in frail older adults. However, its effect on mortality, disability, and hospitalization in frail older adults is poorly investigated. Thus, we assessed the relationship between the prevalence of OH and its effect on mortality, disability, and hospitalization in noninstitutionalized older adults stratified by frailty degree.

METHODS

Prospective, observational study of 510 older participants (≥65 years of age) consecutively admitted to a geriatric evaluation unit to perform a geriatric comprehensive assessment.

MEASUREMENTS

Clinical frailty was assessed using the Italian frailty index (40 items). Systolic blood pressure (mm Hg), diastolic blood pressure (mm Hg), and heart rate (bpm) were evaluated in clinostatic position and after 1, 3, and 5 minutes of orthostatic position. OH was defined with a decrease of 20 mm Hg in systolic blood pressure and/or a decrease of 10 mm Hg in diastolic blood pressure.

RESULTS

OH prevalence was 22%, and it increased from 9.0% to 66.0% according to frailty degree (P for trend <.001). When stratified by frailty degree, mortality, disability, and hospitalization increased from 1.0% to 24.5%, from 39.0% to 77.0% and from 14.0% to 32.0% in the absence, and from 0.0% to 35.5%, from 42.0% to 95.5% and from 19.0% to 65.5% in the presence of OH, respectively (P < .01 vs absence of OH). Multivariate analysis showed that the Italian frailty index is more predictive of mortality, disability, and hospitalization in the presence than in the absence of OH.

CONCLUSIONS

OH is a common condition in frail older adults, and it is strongly associated with mortality, disability, and hospitalization in the highest frailty degree. Thus, OH may represent a new marker of clinical frailty.

Risk of Malnutrition Evaluated by Mini Nutritional Assessment and Sarcopenia in Noninstitutionalized Elderly People

BACKGROUND

Malnutrition indices and muscle mass and strength in the elderly are poorly investigated. Moreover, malnutrition seems to be 1 of the more important factors in the cause of sarcopenia. The presence of sarcopenia and its relationship with malnutrition indices were studied in noninstitutionalized elderly people who underwent Comprehensive Geriatric Assessment (CGA).

METHODS

A total of 473 elderly subjects (mean age, 80.9 ± 6.6 years) admitted to CGA were studied. Malnutrition risk was evaluated with Mini Nutritional Assessment (MNA) score, whereas muscle mass and muscle strength were evaluated by bioimpedentiometry and hand grip, respectively. Sarcopenia was assessed as indicated in the European Working Group on Sarcopenia in Older People (EWGSOP) consensus.

RESULTS

Overall prevalence of sarcopenia was 13.1%, and it increased from 6.1% to 31.4% as MNA decreased (P < .001). MNA score was lower in elderly subjects with sarcopenia (15.4 ± 4.2) than without sarcopenia (22.0 ± 4.0) (P = .024). Linear regression analysis showed that MNA score is linearly related both with muscle mass (r = 0.72; P < .001) and strength (r = 0.42; P < .001). Multivariate analysis, adjusted for several confounding variables including comorbidity and disability, confirmed these results.

CONCLUSIONS

MNA score is low in noninstitutionalized elderly subjects with sarcopenia, and it is linearly related to muscle mass and muscle strength. These data indicate that MNA score, when evaluated with muscle mass and strength, may recognize elderly subjects with sarcopenia.

Social networks and health status in the elderly: the 'ANZIANI IN-RETE' population-based study

BACKGROUND

Certain features of the social environment could maintain and even improve not only psychological well-being, but also health and cognition of the elderly.

AIMS

We tested the association between social network characteristics and the number of chronic diseases in the elderly.

METHODS

A randomized sample of the elderly population of Brescia, Italy, was evaluated (N = 200, age ≥65 years). We performed a comprehensive geriatric assessment, including information on socio-demographic variables (family, friendships, and acquaintance contacts). We measured each person's social network, i.e., degree, efficiency, and variety.

RESULTS

The sample included 118 women and 82 men, mean age 77.7 years. The mean number of chronic diseases was 3.5. A higher social network degree, i.e., more social connections, was associated with fewer diseases. We also found that having more contacts with people similar to each other or intense relationships with people who do not know each other were associated with fewer diseases.

CONCLUSION

More healthy people tend to share certain characteristics of social networks. Our study indicates that it is important to look at diseases and health as complex phenomena, which requires integrating different levels of analysis.

Predictors of transitions in frailty severity and mortality among people aging with HIV

BACKGROUND

People aging with HIV show variable health trajectories. Our objective was to identify longitudinal predictors of frailty severity and mortality among a group aging with HIV.

METHODS

Exploratory analyses employing a multistate transition model, with data from the prospective Modena HIV Metabolic Clinic Cohort Study, based in Northern Italy, begun in 2004. Participants were followed over four years from their first available visit. We included all 963 participants (mean age 46.8±7.1; 29% female; 89% undetectable HIV viral load; median current CD4 count 549, IQR 405-720; nadir CD4 count 180, 81-280) with four-year data. Frailty was quantified using a 31-item frailty index. Outcomes were frailty index score or mortality at four-year follow-up. Candidate predictor variables were baseline frailty index score, demographic (age, sex), HIV-disease related (undetectable HIV viral load, current CD4+ T-cell count, nadir CD4 count, duration of HIV infection, and duration of antiretroviral therapy [ARV] exposure), and behavioral factors (smoking, injection drug use (IDU), and hepatitis C virus co-infection).

RESULTS

Four-year mortality was 3.0% (n = 29). In multivariable analyses, independent predictors of frailty index at follow-up were baseline frailty index (RR 1.06, 95% CI 1.05-1.07), female sex (RR 0.93, 95% CI 0.87-0.98), nadir CD4 cell count (RR 0.96, 95% CI 0.93-0.99), duration of HIV infection (RR 1.06, 95% CI 1.01-1.12), duration of ARV exposure (RR 1.08, 95% CI 1.02-1.14), and smoking pack-years (1.03, 1.01-1.05). Independent predictors of mortality were baseline frailty index (OR 1.19, 1.02-1.38), current CD4 count (0.34, 0.20-0.60), and IDU (2.89, 1.30-6.42).

CONCLUSIONS

Demographic, HIV-disease related, and social and behavioral factors appear to confer risk for changes in frailty severity and mortality among people aging with HIV.

All-cause mortality and multimorbidity in older adults: The role of social support and loneliness

OBJECTIVES

To determine whether the effect of multimorbidity on time to mortality is modified by level of social support and loneliness in a representative sample of 2113 participants aged 60+.

METHODS

Vital status was ascertained through national registers or by asking participants' relatives. Baseline variables included number of illnesses, self-perceived social support (Oslo social support scale) and loneliness (UCLA loneliness scale). Kaplan-Meier survival curves were used to estimate the time to death by multimorbidity, social support and loneliness. Adjusted cox proportional hazards regression models were conducted to explore interactions between multimorbidity and social support and loneliness.

RESULTS

Multimorbidity was associated with low probability of survival, whereas high loneliness and low social support were not related with time to death. Only the interaction multimorbidity∗social support was significant. Participants with low social support and 2 chronic diseases, compared with none, presented lower probability of survival (HR=2.43, 95%CI=1.14-5.18, p<0.05), whereas the effect of multimorbidity, in comparison with not having chronic conditions, did not affect mortality if participants had high social support. For participants with low social support, there were no differences between having one, two or more than two diseases. When there is high social support, the probability of death is significantly lower if one or two chronic diseases are present, compared with more than two.

DISCUSSION

These findings indicate that having a supportive social environment increases the survival of people with physical illnesses, especially those with one or two. For those with more than two illnesses, survival remains unchanged regardless of the level of social support and other protective factors should be explored in future research. Geriatric health professionals are encouraged to evaluate social relationships and stimulate support given by relatives, friends or neighbors.

The Italian version of the "frailty index" based on deficits in health: a validation study

BACKGROUND AND AIM

Several measurements were taken for frailty classification in geriatric population. "Frailty index" is based on "deficits in health," but it is still not available in Italian version. Thus, the aim of the present work was to validate a version of "frailty index" for the Italian geriatric community.

METHODS

The validation of Italian frailty index (IFi) is based on a cohort study that enrolled 1077 non-disabled outpatients aged 65 years or older (81.3 ± 6.5 years) in Naples (Italy). IFi has been expressed as a ratio of deficits present/deficits considered after a comprehensive geriatric assessment. IFi was stratified in light, moderate and severe frailty. Mortality, disability (considering an increase in ADL lost ≥1 from the baseline) and hospitalization were considered at 3, 6, 12, 18 and 24 months of follow-up. Area under curve (AUC) was evaluated for both Fried's and IFi frailty index.

RESULT

At the end of follow-up, mortality increased from 1.0 to 30.3%, disability from 40.9 to 92.3% and hospitalization from 0.0 to 59.0% (p < 0.001 for trend). Multivariate analysis shows that the relative risk for unit increase in IFi is 1.09 (95% CI = 1.01-1.17, p = 0.013) for mortality, 1.04 (95% CI = 1.01-1.06, p = 0.024) for disability and 1.03 (95% CI = 1.01-1.07, p = 0.041) for hospitalization. AUC is higher in IFi with respect to Fried's frailty index when considering mortality (0.809 vs. 0.658, respectively), disability (0.800 vs. 0.729, respectively) and hospitalization (0.707 vs. 0.646, respectively).

CONCLUSIONS

IFi is a valid measure of frailty after the comprehensive geriatric assessment in an Italian cohort of non-institutionalized patients.

Heart failure management in the elderly - a public health challenge

Heart failure (HF) is a rapidly growing public health problem and the leading cause of morbidity, mortality, and hospitalization in populations > 65 years. The elderly HF patients have an increased prevalence of HF with preserved ejection fraction and comorbidities, may present with atypical symptoms and signs, have a higher risk for adverse drug reactions, and worse prognosis as compared with younger patients. Moreover, there is a lack of evidence-based therapies for this population because they are underrepresented in the clinical trials. The elderly are less likely to be evaluated by a cardiologist and to be treated in accordance with recommendations of the current HF guidelines. Although the treatment is improving, it is still suboptimal; therefore, HF in elderly patients requires mobilization of public health services and improvement of treatment strategies.

Tinetti mobility test is related to muscle mass and strength in non-institutionalized elderly people

Elderly people are characterized by a high prevalence of falls and sarcopenia. However, the relationship among Tinetti mobility test (TMT) score, a powerful tool to detect elderly people at risk of falls, and sarcopenia is still not thoroughly investigated. Thus, to determine the relationship between TMT score and muscle mass and strength, 337 elderly participants (mean age 77.1 ± 6.9 years) admitted to comprehensive geriatric assessment were enrolled. TMT score, muscle mass by bioimpedentiometer, and muscle strength by grip strength were evaluated. Muscle mass progressively decreased as TMT score decreased (from 15.3 ± 3.7 to 8.8 ± 1.8 kg/m²; p for trend <0.001). Similarly, muscle strength decreased progressively as Tinetti score decreased (from 34.7 ± 8.0 to 23.7 ± 8.7 kg; p for trend 0.001). Linear regression analysis demonstrated that TMT score is linearly related with muscle mass (y = 4.5x + 0.4, r = 0.61; p < 0.01) and strength (y = 14.0x + 0.8, r = 0.53; p < 0.01). Multivariate analysis confirms the strong relationship between the TMT score and muscle mass (r = 0.48, p = 0.024) and strength (r = 0.39, p = 0.046). The present study indicates that TMT score is significantly related to muscle mass and strength in non-institutionalized elderly participants. This evidence suggests that TMT score, together with evaluation of muscle mass and strength, may identify sarcopenic elderly participants at high risk of falls.

Multimorbidity and mortality in older adults: A systematic review and meta-analysis

OBJECTIVE

To review literature and provide a pooled effect for the association between multimorbidity and mortality in older adults.

METHODS

A systematic review was performed of articles held on the PUBMED database published up until January 2015. Studies which used different diseases and other conditions to define frailty, evaluated multimorbidity related only to mental health or which presented disease homogeneity were not included. A meta-analysis using random effect to obtain a pooled effect of multimorbidity on mortality in older adults was conducted only with studies which reported hazard ratio (HR). Stratified analysis and univariate meta-regression were performed to evaluate sources of heterogeneity.

RESULTS

Out of 5806 identified articles, 26 were included in meta-analysis. Overall, positive association between multimorbidity and mortality [HR: 1.44 (95%CI: 1.34; 1.55)] was detected. The number of morbidities was positively related to risk of death [HR: 1.20 (95%CI: 1.10; 1.30)]. Compared to individuals without multimorbidity, the risk of death was 1.73 (95%CI: 1.41; 2.13) and 2.72 (95%CI: 1.81; 4.08) for people with 2 or more and 3 or more morbidities, respectively. Heterogeneity between studies was high (96.5%). The sample, adjustment and follow-up modified the associations. Only nine estimates performed adjustment which included demographic, socioeconomic and behaviour variables. Disabilities appear to mediate the effect of multimorbidity on mortality.

CONCLUSIONS

Multimorbidity was associated with an increase in risk of death. Multimorbidity measurement standardization is needed to produce more comparable estimates. Adjusted analysis which includes potential confounders might contribute to better understanding of causal relationships between multimorbidity and mortality.

Prognostic role of lactate on mortality in younger and older patients with cardio-respiratory failure admitted to an acute intensive care unit

BACKGROUND AND AIM

Acidosis is able to induce negative changes of different organs that increase progressively with aging. At present it is not known whether the levels of lactate may differently influence the prognosis of younger and older patients. Thus, the aim of this study is to evaluate the prognostic value of lactate levels after admission of younger and older patients to an acute intensive care unit.

METHODS

Younger (<65 years, n = 118) and older (≥65 years, n = 165) patients admitted to an acute intensive care unit were prospectively enrolled and classified according to diagnosis of acute heart or/and respiratory failure. For each patient, APACHE II score, time of hospitalization and mortality, blood levels of lactate were collected.

RESULTS

Both in-hospital mortality and lactate >2.5 mmol/L at the admission was higher in the older than in the younger patients (42.4 vs. 20.3 %, p < 0.01 and 57.8 vs. 31.9 %, p < 0.01, respectively). Lactate level was higher in older than in the younger patients both at admission and after 24 h (3.9 ± 3.4 vs. 2.4 ± 2.2 mmol/L and 2.4 ± 2.0 vs. 1.4 ± 1.3 mmol, p < 0.01, respectively). Accordingly, multivariate analysis shows that lactate was predictive of mortality in younger (OR = 2.65, 95 % CI 1.62-5.24, p = 0.03) and even more in the older (OR = 4.74, 95 % CI 2.10-6.70, p < 0.01) patients.

CONCLUSIONS

Lactate concentration increase is associated with increased mortality in younger patients but, even more so, in older patients admitted to an acute intensive care unit. These results confirm the experimental evidence showing acidosis has a greater effect of leading to organ failure and higher mortality with increasing age.

Assessment of Continuity of Care among Patients with Multiple Chronic Conditions in Italy

The aims of the present study were to evaluate the extent of continuity of care and to investigate its association with several factors among a sample of outpatients with chronic diseases in Italy. The survey was conducted, using face to face interview, from March to December 2014 in a random sample of 633 outpatients with chronic conditions who were going in cardiology, metabolic disorders, and respiratory ambulatory center of four hospitals. A multivariate ordered logistic regression model was used to identify factors associated with the outpatients continuity of care. The mean of the Bice-Boxerman continuity of care (COC) index related to the entire sample was 0.44, and 27.9%, 58.4%, 13.7% had a low, intermediate, and high value of the index based on the tertiles of the distribution. The results of the ordered logistic regression analysis showed that female patients, those older, those who had a lower score of Katz Index of independence in activities of daily living, those who had a lower Charlson et al. comorbidity score, and those who had no hospitalization in the last year, were significantly more likely to have a higher value of the COC index. Patients who had completed a secondary school education had significantly lower odds of having a high value of COC index in comparison to patients with a college degree educational level. Policy makers and clinicians involved in the care of patients should implement comprehensively and efficiently efforts in order to improve the continuity of care in patients with chronic diseases.

Butyryl-cholinesterase is related to muscle mass and strength. A new biomarker to identify elderly subjects at risk of sarcopenia

AIMS

To determine the relationship between Butyryl-cholinesterase (α-glycoprotein synthesized in the liver, b-CHE) and muscle mass and strength.

METHODS

Muscle mass by bioimpedentiometer and muscle strength by grip strength were evaluated in 337 elderly subjects (mean age: 76.2 ± 6.7 years) admitted to comprehensive geriatric assessment.

RESULTS

b-CHE levels were lower in sarcopenic than in nonsarcopenic elderly subjects (p < 0.01). Linear regression analysis demonstrated that b-CHE is linearly related with grip strength and muscular mass both in men and women (r = 0.45 and r = 0.33, p < 0.01; r = 0.55 and r = 0.39, p < 0.01; respectively). Multivariate analysis confirms this analysis.

CONCLUSIONS

b-CHE is related to muscle mass and strength in elderly subjects. Thus, b-CHE may be considered to be a fair biomarker for identifying elderly subjects at risk of sarcopenia.

Companion Versus Comparison: Examining Seeking Social Companionship or Social Comparison as Characteristics That Differentiate Happy and Unhappy People

Which friend do you want to spend time with-a happy friend who performs better than you or an unhappy friend who performs worse than you? The present research demonstrates that in such conflicting situations, when the desires for companionship and comparison are pitted against each other, one's level of happiness plays an important role in one's choice. Using hypothetical scenarios, we found that compared with unhappy people, happy people expected that spending time with a happy, superior friend would be more pleasant than spending time with an unhappy, inferior friend (Studies 1B through 2) and were more willing to socialize with a happy, superior friend than with an unhappy, inferior friend (Studies 1B through 2). Moreover, this pattern was not explained by self-esteem (Study 2) or the similarity-attraction hypothesis (Study 3). The present findings suggest that happy people place more value on companionship than on comparison.

Suicidal Ideation Among Korean Elderly: Risk Factors and Population Attributable Fractions

OBJECTIVES

The objective of this study was to investigate the risk factors of suicidal ideation and their population attributable fraction (PAF) in a representative sample of the elderly population in Korea.

METHOD

We examined the data set from the Survey of Living Conditions and Welfare Needs of Korean Older Persons, which was conducted by the Korea Institute for Health and Social Affairs (KIHASA) in 2011. In that survey, 10,674 participants were randomly selected from those older than age 65. Simultaneous multivariate logistic regression was used to investigate the risk factors of suicidal ideation in terms of their sociodemographic and health-related variables. Subsequently, the PAF was calculated with adjustment for other risk factors.

RESULTS

The weighted prevalences of depression and suicidal ideation were 30.3% and 11.2%, respectively. In multivariate analysis, factors significantly associated with decreased risk of suicidal ideation included old-old age (odds ratio [OR] = 0.66 for 75 to 79 years, OR = 0.52 for 80 to 84 years, OR = 0.32 for older than 85 years), economic status (OR = 0.59 for 5th quintile; more than US$25,700 per year), whereas those associated with increased risk included poor social support (OR = 1.28), currently smoking (OR = 1.42), sleep problems (OR = 1.74), chronic illness (OR = 1.40), poor subjective health (OR = 1.56), functional impairment (OR = 1.45), and depression (OR = 4.36). Depression was associated with a fully adjusted PAF of 45.7%, followed by chronic illness (19.4%), poor subjective health status (18.9%), sleep problems (14.1%), functional impairment (4.9%), poor social support (4.2%), and currently smoking (3.6%).

CONCLUSIONS

Preventive strategies focused particularly on depression might reduce the impact of suicidal ideation in the elderly population. Also, specific mental health centers focused on the specific needs of the elderly population should be established to manage suicidal risk.

Multi-Morbidity in Hospitalised Older Patients: Who Are the Complex Elderly?

Background

No formal definition for the “complex elderly” exists; moreover, these older patients with high levels of multi-morbidity are not readily identified as such at point of hospitalisation, thus missing a valuable opportunity to manage the older patient appropriately within the hospital setting.

Objectives

To empirically identify the complex elderly patient based on degree of multi-morbidity.

Design

Retrospective observational study using administrative data.

Setting

English hospitals during the financial year 2012–13.

Subjects

All admitted patients aged 65 years and over.

Methods

By using exploratory analysis (correspondence analysis) we identify multi-morbidity groups based on 20 target conditions whose hospital prevalence was ≥ 1%.

Results

We examined a total of 2788900 hospital admissions. Multi-morbidity was highly prevalent, 62.8% had 2 or more of the targeted conditions while 4.7% had six or more. Multi-morbidity increased with age from 56% (65-69yr age-groups) up to 67% (80-84yr age-group). The average multi-morbidity was 3.2±1.2 (SD). Correspondence analysis revealed 3 distinct groups of older patients. Group 1 (multi-morbidity ≤2), associated with cancer and/or metastasis; Group 2 (multi-morbidity of 3, 4 or 5), associated with chronic pulmonary disease, lung disease, rheumatism and osteoporosis; finally Group 3 with the highest level of multi-morbidity (≥6) and associated with heart failure, cerebrovascular accident, diabetes, hypertension and myocardial infarction.

Conclusions

By using widely available hospital administrative data, we propose patients in Groups 2 and 3 to be identified as the complex elderly. Identification of multi-morbidity patterns can help to predict the needs of the older patient and improve resource provision.

La influencia del apoyo social en usuarios institucionalizados socialmente vulnerables || The influence of social support on institutionalized socially vulnerable users

Así, el objetivo de la investigación ha sido desarrollar un modelo que explique como el contacto con la familia conlleva a una mayor satisfacción en la población institucionalizada  través de variables como el apoyo social percibido, aislamiento y autoestima Los resultados obtenidos confirman que el apoyo afectivo y las visitas recibidas predicen la satisfacción, pero están mediados por el apoyo informativo. Asimismo, un alto apoyo social conlleva a una mayor autoestima y satisfacción, y la falta de este a un mayor aislamiento social. 

Does comprehensive geriatric assessment improve the estimate of surgical risk in elderly patients? An Italian multicenter observational study

BACKGROUND

The evaluation of surgical risk is crucial in elderly patients. At present, there is little evidence of the usefulness of comprehensive geriatric assessment (CGA) as a part of the overall assessment of surgical elderly patients.

METHODS

We verified whether CGA associated with established surgical risk assessment tools is able to improve the prediction of postoperative morbidity and mortality in 377 elderly patients undergoing elective surgery.

RESULTS

Overall mortality and morbidity were 2.4% and 19.9%, respectively. Multivariate analysis showed that impaired cognitive function (odds ratio [OR], 1.33; 95% confidence interval [CI], 1.15 to 4.22; P < .02) and higher Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (OR, 1.11; 95% CI, 1.00 to 1.23; P < .04) are predictive of mortality. Higher comorbidity is predictive of morbidity (OR, 2.12; 95% CI, 1.06 to 4.22; P < .03) and higher American Society of Anesthesiologists (OR, 2.18; 95% CI, 1.31 to 3.63; P < .001) and National Confidential Enquiry into Patient Outcome of Death score (OR, 2.03; 95% CI, 1.03 to 4.00; P < .04).

CONCLUSIONS

In elective surgical elderly patients, the morbidity and mortality are low. The use of CGA improves the identification of elderly patients at higher risk of adverse events, independent of the surgical prognostic indices.

Gender differences in the roles for social support in ensuring adequate fruit and vegetable consumption among older adult Canadians

BACKGROUND

Adequate fruit and vegetable consumption has been linked to reductions in all-cause mortality, stroke, and cancer. Unfortunately, less than half of Canadians aged 65+ meet the standard international guideline for adequate consumption (≥5 servings per day). Among older adults, social isolation and low social support are barriers to proper nutrition, but the effects of specific types of social support on adequate fruit and vegetable consumption are unknown.

OBJECTIVE

This study sought to test hypotheses regarding direct and indirect pathways through which tangible and emotional/informational social support may facilitate adequate fruit and vegetable consumption among older adults.

METHODS

Analyzing 2008-2009 Canadian Community Health Survey - Healthy Aging component data (n = 14,221), logistic regression models were developed to examine associations between tangible and emotional/informational social support, eating behaviors (eating alone and preparing one's own meals), and meeting the recommended guideline of consuming ≥5 servings of fruit and vegetables per day.

RESULTS

In pooled models, emotional/informational support was positively associated with adequate fruit and vegetable consumption (OR = 1.16; 95% CI = 1.07, 1.27). Among men, neither social support form was directly or indirectly associated with adequate consumption; among women, adequate consumption was negatively associated with tangible support but positively associated with higher emotional/informational support. Both of these associations were mediated by not usually cooking one's own meals.

CONCLUSIONS

Programs and policies that seek to foster social support for older adults as a means of ensuring proper nutrition should consider the nuanced mechanisms through which different social support forms may operate for men and women.

Providing instrumental social support is more beneficial to reduce mortality risk among the elderly with low educational level in Taiwan: a 12-year follow-up national longitudinal study

BACKGROUND

To evaluate whether the effects of providing or receiving social support are more beneficial to reduce mortality risk among the elderly with different educational levels.

METHODS

In this long-term prospective cohort study, data were retrieved from the Taiwan Longitudinal Study on Aging. This study was initiated from 1996 until 2007. The complete data from 1492 males and 1177 females aged ≥67 years were retrieved. Participants received financial, instrumental, and emotional support, and they actively provided instrumental and emotional support to others and involved in social engagement. Education attainment was divided into two levels: high and low. The low education level included illiterate and elementary school. The high education level included junior high school to senior high school and above college. Cox regression analysis was used to examine the association between providing or receiving social support on mortality with different educational levels.

RESULTS

The average age of the participants in 1996 was 73.0 (IQR=8.0) years, and the median survival following years (1996-2007) of participants was 10.3 (IQR=6.7) years. Most participants were low educational level including illiterate (39.3%) and elementary school (41.2%). Participants with high educational level tend to be younger and more male significantly. On the contrary, participants with low educational level tend to have significant more poor income, more depression, more cognition impairment, more with IADL and ADL disability than high educational level. Most participants received instrumental support from others (95.5%) and also provided emotional support to others (97.7%). Providing instrumental support can reduce 17% of mortality risk among the elderly with a low level of education after adjusting several covariates [Hazard ratio (HR) = 0.83; 95% confidence interval (CI) = 0.70-0.99; p = 0.036].

CONCLUSIONS

Providing instrumental social support to others confer benefits to the giver and prolong life expectancy among the elderly with low educational levels.

Correlates of social support in older American Indians: the Native Elder Care Study

OBJECTIVES

This study examined social support and identified demographic and health correlates among American Indians aged 55 years and older.

METHODS

Data were derived from the Native Elder Care Study, a cross-sectional study of 505 community-dwelling American Indians aged ≥55 years. Social support was assessed using the Medical Outcomes Study Social Support Survey measure (MOS-SSS) of which psychometric properties were examined through factor analyses. Logistic regression analyses were used to identify associations between age, sex, educational attainment, marital status, depressive symptomatology, lower body physical functioning, and chronic pain and social support.

RESULTS

Study participants reported higher levels of affectionate and positive interaction social support (88.2% and 81.8%, respectively) than overall (75.9%) and emotional (69.0%) domains. Increased age, being married/partnered, and female sex were associated with high social support in the final model. Decreased depressive symptomatology was associated with high overall, affectionate, and positive interaction support, and decreased chronic pain with affectionate support. The count of chronic conditions and functional disability were not associated with social support.

CONCLUSIONS

Overall, we found high levels of social support for both men and women in this population, with the oldest adults in our study exhibiting the highest levels of social support. Strong cultural values of caring for older adults and a historical tradition of community cooperation may explain this finding. Future public health efforts may be able to leverage social support to reduce health disparities and improve mental and physical functioning.

Social support and mortality among the aged people with major diseases or ADL disabilities in Taiwan: a national study

OBJECTIVE

To determine the effects of social support on mortality among the aged people with major diseases or ADL disabilities.

METHOD

In this prospective cohort study, data were retrieved from the Taiwan Longitudinal Study on Aging from 1996 to 2007. Data for 1297 males and 1666 females aged ≥65 years were collected. The participants were divided into having major diseases or ADL disability or none. Subjects received financial, instrumental, and emotional support, and they actively provided instrumental and emotional support to others. The effect of the association between providing and receiving social support on mortality was examined using Cox regression analysis after adjusting several covariates.

RESULTS

Results showed a significant finding that providing instrumental support can lower mortality rates in the aged people [Hazard ratio (HR)=0.77; 95% confidence interval (CI)=0.66-0.90; p=0.0009] and those with major diseases or impairment of activities of daily living [Hazard ratio (HR)=0.62; 95% confidence interval (CI)=0.50-0.78; p≤0.0001] after adjusting for several covariates. Providing instrumental social support to others may prolong life expectancy in the aged people and even those with major diseases or those facing difficulties performing ADL.

CONCLUSION

Based on the finding, we should encourage older adults who have major diseases or ADL disabilities to be supporting providers especially in providing instrumental social support.

Cognitive impairment and cardiovascular diseases in the elderly. A heart-brain continuum hypothesis

The aging population is increasing and, therefore, a higher prevalence of cardiac disease is emerging; including hypertension, coronary artery disease, atrial fibrillation and chronic heart failure. Large cohort studies have revealed a relationship among increased risk for cognitive impairment and dementia in cardiovascular diseases probably due to embolic stroke or chronic cerebral hypoperfusion. Thus, the aim of the present review is to overview the studies that investigate the presence and/or the development of cognitive impairments and dementia in patients with varied types of cardiovascular disease. Finally, a continuum among hypertension, coronary artery disease, atrial fibrillation and chronic heart failure with to the development of cognitive impairment and progression to dementia has been hypothesized.

Comorbidity structure of psychological disorders in the online e-PASS data as predictors of psychosocial adjustment measures: psychological distress, adequate social support, self-confidence, quality of life, and suicidal ideation

Background

A relative newcomer to the field of psychology, e-mental health has been gaining momentum and has been given considerable research attention. Although several aspects of e-mental health have been studied, 1 aspect has yet to receive attention: the structure of comorbidity of psychological disorders and their relationships with measures of psychosocial adjustment including suicidal ideation in online samples.

Objective

This exploratory study attempted to identify the structure of comorbidity of 21 psychological disorders assessed by an automated online electronic psychological assessment screening system (e-PASS). The resulting comorbidity factor scores were then used to assess the association between comorbidity factor scores and measures of psychosocial adjustments (ie, psychological distress, suicidal ideation, adequate social support, self-confidence in dealing with mental health issues, and quality of life).

Methods

A total of 13,414 participants were assessed using a complex online algorithm that resulted in primary and secondary Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition, Text Revision) diagnoses for 21 psychological disorders on dimensional severity scales. The scores on these severity scales were used in a principal component analysis (PCA) and the resulting comorbidity factor scores were related to 4 measures of psychosocial adjustments.

Results

A PCA based on 17 of the 21 psychological disorders resulted in a 4-factor model of comorbidity: anxiety-depression consisting of all anxiety disorders, major depressive episode (MDE), and insomnia; substance abuse consisting of alcohol and drug abuse and dependency; body image–eating consisting of eating disorders, body dysmorphic disorder, and obsessive-compulsive disorders; depression–sleep problems consisting of MDE, insomnia, and hypersomnia. All comorbidity factor scores were significantly associated with psychosocial measures of adjustment (P<.001). They were positively related to psychological distress and suicidal ideation, but negatively related to adequate social support, self-confidence, and quality of life.

Conclusions

This exploratory study identified 4 comorbidity factors in the e-PASS data and these factor scores significantly predicted 5 psychosocial adjustment measures.

Phase angle as bioelectrical marker to identify elderly patients at risk of sarcopenia

Several markers have been associated with sarcopenia in the elderly, including bioelectrical indices. Phase angle (PhA) is an impedance parameter and it has been suggested as an indicator of cellular death. Thus, the relationship between PhA and muscle mass and strength was investigated in 207 consecutively elderly participants (mean age 76.2±6.7years) admitted for multidimensional geriatric evaluation. Muscle strength by grip strength using a hand-held dynamometer and muscle mass was measured by bioimpedentiometer. PhA was calculated directly with its arctangent (resistance/reactance×180°/π). Linear relationship among muscular mass and strength and with clinical and biochemical parameters, including PhA at uni- and multivariate analysis were performed. Linear regression analysis demonstrated that lower level of PhA is associated with reduction in grip strength (y=3.16+0.08x; r=0.49; p<0.001), and even more, with muscle mass (y=3.04+0.25x; r=0.60; p<0001). Multivariate analysis confirms these relationships (grip strength β=0.245, p=0.031; muscular mass β=0.623, p<0.01). Thus, PhA is inversely related to muscle mass and strength in elderly subjects and it may be considered a good bioelectrical marker to identify elderly patients at risk of sarcopenia.

Predictors of suicidal ideation in older individuals receiving home-care services

OBJECTIVES

Despite the importance of tending to older individuals who are vulnerable to suicide, little is known about suicidal ideation in the portion of this population receiving home-care services in Asian countries. The objective of this cross-sectional study was to examine predictors of suicidal ideation in older individuals using home-care service.

METHOD

Participants were randomly selected from the individuals 50 years old and over using home-care services across Jeollabuk-do Province, Korea. A total of 697 subjects participated in this study. Each participant completed the short version of the Geriatric Depression Scale, the Scale for Suicidal Ideation, the Multidimensional Scale of Perceived Social Support, and the World Health Organization Disability Assessment Schedule II.

RESULTS

Hierarchical regression analyses revealed that depression, perceived social support, and disability were significant predictors of suicidal ideation, whereas the roles of subjective health status and fish consumption remained ambiguous in this regard. In terms of social support, we also found that less perceived social support from family members was related to higher levels of suicidal ideation. The associations between various categories of disability and suicidal ideation disappeared after controlling for depression. Our investigation of the mediating effect of depression on the relationship between disability and suicidal ideation revealed that depression was either a complete (disability related to cognition, self-care, getting along with others, and life activities) or partial (disability related to participation) mediator.

CONCLUSIONS

Preventive strategies focusing on depression, social support, and disability should be emphasized during encounters with older people receiving home-care services.
