Depressive symptoms of older adults with chronic diseases: the mediating roles of activities of daily living and economic burden of diseases

Objective

To explore the mediating roles of activities of daily living (ADL) and economic burden of diseases in the relationship between chronic diseases and depressive symptoms of older adults.

Methods

The data were sourced from China Health and Retirement Longitudinal Study (CHARLS). The number of chronic diseases, ADL, out-of-pocket medical expenses and the Center for Epidemiological Studies Depression Scale (CES-D) were selected as measuring indexes. Mediation analysis was conducted to explore the potential mediating roles of ADL and economic burden of diseases in the association between chronic diseases and depressive symptoms.

Results

The number of chronic diseases, ADL, economic burden of diseases and depressive symptoms of older adults were significantly correlated with each other. ADL and economic burden of diseases individually mediated the relationship between the number of chronic diseases and depressive symptoms, accounting for 31.460% and 5.471% of the total effect, respectively. Additionally, ADL and economic burden of diseases demonstrated a chain mediating effect in this relationship, contributing to 0.759% of the total effect.

Conclusion

The chain-mediated model effectively elucidated the mediating roles of ADL and economic burden of diseases in the association between chronic diseases and depressive symptoms among older adults. The study underscores the need for policymakers to focus attentively on the mental health of older adults with chronic diseases. Enhancing the capacity for ADL and strengthening social security to mitigate the economic burden of diseases are recommended strategies to alleviate depressive symptoms in older adults.

Prevalence of early and late onset of chronic diseases and multimorbidity and its association with physical, mental and functional health among older Indian adults

BACKGROUND

Identifying people with early and late onset of chronic conditions might help target the subpopulations that are more vulnerable to negative mental, physical and functional health outcomes. The current study aimed to examine the association of early and late onset of chronic single and multiple morbidities with self-perceived physical and mental health, functional limitations and physical inactivity among older Indian adults.

METHODS

Cross-sectional study was conducted using data from the Longitudinal Ageing Study in India (LASI) Wave 1 (2017-2018). The total sample size for the present study was 31,386 older adults age 60 years or older. Multivariable binary logistic regression analysis was used to establish the association between the outcomes (poor perceived physical/mental health, functional difficulty and physical inactivity) and explanatory variables (early [ = < 50 years of age] and late [> 50 years]) onset of chronic illnesses such as hypertension, diabetes, heart attack, heart disease, stroke, cancer, lung disease, arthritis, osteoporosis and psychiatric disease).

RESULTS

Overall, 24.21% of the sample population had poor self-perceived physical health, whereas 8.67% of participants had poor self-perceived mental health. The prevalence of difficulty in ADL, difficulty in IADL, and physical inactivity was 23.77%, 48.36%, and 68.9%, respectively. Odds of poor perceived mental health were higher for the respondents with early as well as late onset of hypertension, stroke, and arthritis; while individuals with late onset of diabetes, and heart disease had higher odds of poor perceived mental health than those without chronic disease. Individuals with early onset of single morbidity were more likely to report ADL difficulty (adjusted odds ratio [AOR]: 1.33, confidence interval [CI]: 1.06-1.67); while those with late onset of single (AOR: 1.34, CI: 1.17-1.53) and multimorbidity (AOR: 1.91, CI: 1.63-2.24) were more likely to report ADL difficulty compared with individuals without morbidity. Individuals with early as well as late-onset of multimorbidity had more than two times higher odds of reporting poor physical health, poor mental health and IADL difficulty compared with individuals without chronic disease.

CONCLUSIONS

The present study revealed that early and/or late onset of chronic single and/or multiple morbidities significantly predicted poor self-perceived physical and mental health, functional limitations and physical inactivity among older Indian adults. The findings further suggest that late onset of chronic diseases such as cancer and stroke and multi-morbidity had stronger associations with physical inactivity that may help identify high risk groups for screening and support.

Prevalence and Clinical Conditions Related to Sarcopaenia among Older Persons Living in the Community

(1) Background: In health care and in society at large, sarcopaenia is a disorder of major importance that can lead to disability and other negative health-related events. Our study aim is to determine the prevalence of sarcopaenia among older people attended in primary care and to analyse the factors associated with this age-related clinical condition; (2) Methods: A multicentre cross-sectional study was conducted of 333 community-dwelling Spanish adults aged 65 years or more. Sociodemographic, clinical, functional, anthropometric, and pharmacological data were collected. Sarcopaenia was defined following European Working Group on Sarcopaenia in Older People (EWGSOP) criteria; (3) Results: Sarcopaenia was present in 20.4% of the study sample, and to a severe degree in 6%. The intensity of the association between sarcopaenia and frailty was weak-moderate (Cramer V = 0.45). According to the multinomial logistic regression model performed, sarcopaenia was positively associated with age and with the presence of psychopathology (OR = 2.72; 95% CI = 1.30–5.70) and was inversely correlated with body mass index (OR = 0.73, 95% CI = 0.67–0.80; (4) Conclusions: Sarcopaenia commonly affects community-dwelling older persons and may be associated with age, body mass index, and psychopathology. The latter factor may be modifiable or treatable and is therefore a possible target for intervention.

Multivariate decomposition analysis of sex differences in functional difficulty among older adults based on Longitudinal Ageing Study in India, 2017-2018

OBJECTIVES

This study investigates the gender disparities in difficulty in activities of daily living (ADL) and instrumental activities of daily living (IADL) and explores its contributing factors among older adults in India.

DESIGN

A cross-sectional study was conducted using country representative survey data.

SETTING AND PARTICIPANTS

The present study uses the data from the Longitudinal Ageing Study in India, 2017-2018. Participants included 15 098 male and 16 366 female older adults aged 60 years and above in India.

PRIMARY AND SECONDARY OUTCOME MEASURES

Difficulty in ADL and IADL were the outcome variables. Descriptive statistics and bivariate analysis were carried out to present the preliminary results. Multivariate decomposition analysis was used to identify the contributions of covariates that explain the group differences to average predictions.

RESULTS

There was a significant gender differential in difficulty in ADL (difference: 4.6%; p value<0.001) and IADL (difference: 17.3%; p value<0.001). The multivariate analysis also shows significant gender inequality in difficulty in ADL (coefficient: 0.046; p value<0.001) and IADL (coefficient: 0.051; p value<0.001). The majority of the gender gap in difficulty in ADL was accounted by the male-female difference in levels of work status (18%), formal education (15% contribution), marital status (13%), physical activity (9%), health status (8%) and chronic morbidity prevalence (5%), respectively. Equivalently, the major contributors to the gender gap in difficulty in IADL were the level of formal education (28% contribution), marital status (10%), alcohol consumption (9%), health status (4% contribution) and chronic morbidity prevalence (2% contribution).

CONCLUSION

Due to the rapidly increasing ageing population, early detection and prevention of disability or preservation of daily functioning for older adults and women in particular should be the highest priority for physicians and health decision-makers.

Impact of the COVID-19 Pandemic on Elderly Patients with Spinal Disorders

During the ongoing coronavirus disease 2019 (COVID-19) pandemic, home-quarantine has been necessary, resulting in lifestyle changes that might negatively affect patients with spinal disorders, including a reduction in their quality of life (QoL) and activities of daily living (ADLs). However, studies on this impact are lacking. This study aimed to investigate the age-related changes in QoL and ADLs in patients with spinal disorders, and also identify factors associated with decline in ADLs. This multicenter cross-sectional study included patients who visited four private spine clinics for any symptoms. The study participants either had a clinic reservation, were first-time clinic visitors, or had a return visit to the clinic. The participants completed several questionnaires at two points: pre-pandemic and post-second wave. Changes in patient symptoms, exercise habits, ADLs, and health-related QoL were assessed. A logistic regression model was used to calculate the odds ratio (OR) of each variable for decline in ADLs. We included 606 patients; among them, 281 and 325 patients were aged <65 and ≥65 years, respectively. Regarding exercise habits, 46% and 48% of the patients in the <65 and ≥65-year age groups, respectively, did not change their exercise habits. In contrast, 40% and 32% of the patients in the <65 and ≥65-year age groups, respectively, decreased their exercise habits. In the multivariate analysis, the adjusted ORs for sex (female), decreased exercise habit, and age >65 years were 1.7 (1.1–2.9), 2.4 (1.4–3.9), and 2.7 (1.6–4.4), respectively. In conclusion, there was a decline in the ADLs and QoL after the COVID-19 outbreak in patients with spinal disorders. Aging, reduction of exercise habits, and female sex were independent factors related to decline in ADLs.

Number of chronic conditions and associated functional limitations among older adults: cross-sectional findings from the longitudinal aging study in India

Background

Chronic conditions reduce the likelihood of physical functioning among older adults. However, the contribution of most prevalent diseases and multimorbidity to different measures of functional limitations is relatively underexplored among Indian older adults. The present study explores the prospective association between number of chronic conditions and limitations in activities of daily living (ADL) and instrumental activities of daily living (IADL) among older adults in India.

Methods

This study utilized data from the nationally representative Longitudinal Ageing Study in India (LASI-2017-18). The effective sample size was 31,464 older adults aged 60 years and above. Descriptive statistics along with cross-tabulation were presented in the study. Additionally, binary logistic regression analysis was used to fulfil the objectives. The outcome variables were dichotomized; high representing no difficulty in ADL/IADL and low representing a difficulty in at least one ADL/IADL. The chronic conditions included hypertension, diabetes, neurological/psychiatric disease, lung disease, heart diseases, stroke, and bone-related disease. The number of chronic diseases was categorized into no disease, single, two and three plus based on number of reported disease.

Results

26.36% of older women and 20.87% of older men had low ADL and the figures for low IADL were 56.86 and 38.84% for older men and women respectively. The likelihood of low ADL (AOR: 1.698, CI:1.544, 1.868) and low IADL (AOR: 1.197; CI: 1.064, 1.346) was higher among womenthan men. With increasing age, the prevalence of low ADL increased among older adults. Respondents with pre-existing chronic conditions had higher likelihood of low ADL and IADL. Older adults with hypertension, psychiatric disease, heart disease, stroke and bone-related disease had significantly higher odds of reporting low IADL. The chances of low ADL and IADL were 2.156 (CI: 1.709, 2.719) and 2.892 (CI: 2.067, 4.047) times respectively higher among older adults with more than three chronic conditions. After controlling for socio-economic and health-related covariates, it was found that men with more than three pre-existing chronic conditions had higher odds of low ADL than women. On the other hand, low IADL were found higher among women with more than three pre-existing chronic conditions.

Conclusions

The present study demonstrates a significant burden of functional limitations among older individuals and that there is a strong association between pre-existing chronic conditions and functional disability. Those with hypertension, diabetes, psychiatric disorders, heart disease, stroke, lung disease or bone-related diseases should be effectively monitored to predict future functional limitations, which may lead to worsening health.

The relationship between depressive symptoms and activity of daily living disability among the elderly: results from the China Health and Retirement Longitudinal Study (CHARLS)

OBJECTIVE

The acceleration of population aging has brought an unprecedented impact on China's health system. This study is designed to examine the association between depressive symptoms and activity of daily living disability among the elderly in China.

STUDY DESIGN

This is a cross-sectional study.

METHODS

Data were drawn from the China Health and Retirement Longitudinal Study (CHARLS). The 10-item Center for Epidemiologic Studies-Depression (CES-D) scale was used to access depressive symptoms, and physical function was assessed by the Activity of Daily Living (ADL) scale. Multivariate logistic regression was used to assess the association between depressive symptoms and ADL among the elderly.

RESULTS

Based on a sample of 5863 elderly people over 60 years old, our results showed that 1999 elderly people are with depressive symptoms, accounting for 34.1%. The mean score of ADL among the elderly with depressive symptoms (20.65 ± 7.14) was much higher than that in those without depressive symptoms (17.40 ± 4.87). After controlling potential confounders, multivariate logistic regression showed that ADL and its specific domains including personal care, transfer, medical care, household, and managing money were associated with depressive symptoms.

CONCLUSION

This cross-sectional study provides evidence of the association between depressive symptoms and ADL disability among the Chinese elderly. As a result, prevention or reduction of ADL disability may have a positive effect on the medical care of the elderly with depressive symptoms.

Multiple factors associated with life satisfaction in older adults

Introduction

The population of older adults is increasing as science progresses and health conditions improve. Social, psychological and behavioral factors will influence life satisfaction in older adults. We aimed to assess multiple factors associated with life satisfaction in older adults in Qom city, Iran.

Material and methods

It was a descriptive-analytical study which has conducted on 679 older adults through convenience sampling from Qom city, Iran during 2018. The data were collected using demographic characteristics, life satisfaction, well-being, cognitive status, social support, and daily activities of life questionnaire. Data were analyzed by SPSS version 22 software and independent t-test, ANOVA, Pearson’s correlation coefficient and multiple regression analysis.

Results

The mean older adult’s age was 70.43 ± 7.62 years. The mean life satisfaction score was 13.77 ± 3.73. The results showed a significant relationship of job and education with life satisfaction (p < 0.001). The results also showed that social support (p = 0.001) and daily activities (p = 0.017) significantly predict the level of life satisfaction, and the dimensions of health (p = 0.001) and cognitive status (p = 0.007) have a larger share in predicting the satisfaction of older adults’ life.

Conclusions

We found that some parts of life changes in older adults can be predicted with the help of social support, health status, cognitive status, and everyday life activities. Therefore, in order to increase the level of life satisfaction of older adults, it is suggested that promotion of social support, health status, and cognitive status be provided.

Does Gender Matter in the Receipt of Informal Care Among Community-Dwelling Older Adults? Evidence from a Cross-National Comparative Study Across the United States, South Korea, and China

OBJECTIVES

This study compares patterns of gender difference in the receipt of informal care among community-dwelling older adults across the United States, Korea, and China where family-oriented systems for providing care to older adults are emphasized.

METHOD

Data came from the 2014 Health and Retirement Study, the 2014 Korea Longitudinal Study of Aging, and the 2015 China Health and Retirement Longitudinal Study. Logistic regression models were used to predict the receipt of informal care by gender. We also examined how the effects of health and living arrangement on the receipt of informal care differ depending on gender.

RESULTS

In the United States and China, older women were more likely to receive informal care than men. However, older Korean women were less likely to receive informal care than men. The effects of health and living arrangement on the use of informal care were moderated by gender in different ways across countries.

DISCUSSION

This study provides evidence that patterns of gender differences in the receipt of informal care vary across the three countries. More attention needs to be paid to the design and implementation of long-term supports and services to address the unique patterns of gender difference in care arrangement in each country.

Artificial Intelligence Approaches to Social Determinants of Cognitive Impairment and Its Associated Conditions

BACKGROUND AND PURPOSE

This study uses an artificial-intelligence model (recurrent neural network) for evaluating the following hypothesis: social determinants of disease association in a middle-aged or old population are different across gender and age groups. Here, the disease association indicates an association among cerebrovascular disease, hearing loss and cognitive impairment.

METHODS

Data came from the Korean Longitudinal Study of Ageing (2014-2016), with 6,060 participants aged 53 years or more, that is, 2,556 men, 3,504 women, 3,640 aged 70 years or less (70-), 2,420 aged 71 years or more (71+). The disease association was divided into 8 categories: 1 category for having no disease, 3 categories for having 1, 3 categories for having 2, and 1 category for having 3. Variable importance, the effect of a variable on model performance, was used for finding important social determinants of the disease association in a particular gender/age group, and evaluating the hypothesis above.

RESULTS

Based on variable importance from the recurrent neural network, important social determinants of the disease association were different across gender and age groups: 1) leisure activity for men; 2) parents alive, income and economic activity for women; 3) children alive, education and family activity for 70-; and 4) brothers/sisters cohabiting, religious activity and leisure activity for 70+.

CONCLUSIONS

The findings of this study support the hypothesis, suggesting the development of new guidelines reflecting different social determinants of the disease association across gender and age groups.

Quality of Life and Dependence Degree of Chronic Patients in a Chronicity Care Model

Background: The complex chronic patient is a person with one or several long-term diseases, the clinical management of which are considered difficult and related to cognitive or functional impairment. The chronicity care model deeply affects the quality of life and degree of dependence. Objectives: The objective of this study was to analyse the perceived quality of life and dependence degree in complex chronic patients within a chronicity care model in the Autonomous Communities of Cantabria and the Balearic Islands (Spain). Design: This was a multicentred, transversal, descriptive, and observational study on a cohort of 206 chronic patients included in a chronicity care program. Methods: Patients’ sociodemographic variables, integral valuation, nurse follow-up records, nursing outcomes classification (NOC)/nursing interventions classification (NIC), nurse diagnoses, and hospitalization data were analysed. A descriptive analysis of all data was carried out. The bivariate analysis assessed the relation between covariables and the overall scoring in European Quality of Life Scale (EuroQuol-5D), Barthel, Braden, and Chronic Patient eXperience Assessment Instrument (IEXPAC in the Spanish abbreviation). A multivariate linear regression analysis was conducted. Results: The mean age was 79.4 years (standard deviation (SD) = 9.12; range: 39–94). A percentage of 79.3% of the study population shows functional impairment in one or more activities of daily life. A percentage of 83.3% of patients showed a physical dependence. There is a significant relationship between the gender and kinship degree of the caregiver (χ2 = 18.2; p = 0.001). An overall mean score of 55.38 points in EuroQuol-5D was obtained, along with a 36.87-point satisfaction with the care given in IEXPAC. The overall score correlated positively and significantly with Barthel, Braden, and IEXPAC. The dependence levels improved slightly in the observed patients, which was a very significant outcome in statistical terms (t = 2.08; p = 0.039). A percentage of 66% (R2 = 0.66) of the score variability at the Barthel index could be predicted from Braden scale scoring. Conclusions: Dependence is not only affected by the related pathology, but also by the effect on mobility and daily-life activities, which cause a worse perception of the quality of life. The health-care model based on the case management nurse is having positive effects, especially on dependence and patients with ulcer issues.

Effects of the Health Promotion Programs on Happiness

The Healthy City program is a comprehensive health promotion program implemented by local governments to improve citizens’ health. The Healthy City program aims to improve citizens’ quality of life through health promotion activities in daily life. It also improves health by eliminating health risk factors and increasing citizens’ happiness. Therefore, this study investigated the effects of the Healthy City program on the happiness index of local residents and the correlation between the Healthy City program and the happiness index using quality of life as a parameter. We conducted a questionnaire survey of residents of Seoul, where Healthy City networks are actively promoted. A total of 392 responses were obtained. Structural equations were used to analyze the collected data. The Healthy City program had positive effects on the happiness index. In other words, it increased the happiness index by improving the health of the local residents. Relevant policy efforts are also being made to advance health services through Healthy City programs. For an effective Healthy City program, it is necessary to implement policies regarding health equity, to expand Healthy City programs based on a settings approach, and to implement a sustainable Healthy City program through the establishment of Healthy City governance.

Prevalence of self-reported morbidities and associated factors among community-dwelling elderly in Uberaba, Minas Gerais, Brazil

This study aimed to verify the prevalence and socioeconomic and health factors associated with morbidity among community-dwelling elderly. This is an analytical and cross-sectional survey conducted in 2012 with 1,691 elderly from Uberaba-MG. A tool structured for socioeconomic data and self-reported morbidities was used along with the Abbreviated Geriatric Depression, Katz and Lawton-Brody scales. We proceeded to a descriptive analysis and linear regression (p < 0.05). A high percentage (88.3%) of elderly reported two or more morbidities, with higher prevalence for systemic arterial hypertension (61.9%) and back problems (48.6%). Female gender (β = 0.216; p< 0.001), functional disability in basic (β = 0.240; p < 0.001) and instrumental activities of daily living (β = 0.120; p < 0.001) and indicative of depression (β = 0.209; p < 0.001) were associated with the highest number of morbidities. The presence of two or more comorbidities and the association with socioeconomic and health variables show the need for monitoring and control actions of the factors that interfere in the elderly in this condition.

Functional Status of Patients with COPD Assessed by London Chest Activity of Daily Living Scale: Gender Association and Validity of a Cutoff Point

PURPOSE

Whether the difference in the impact of chronic obstructive pulmonary disease (COPD) on the functional status of men and women stems from clinical distinctions or to the measuring instrument used is unclear. Like most instruments for assessing functional limitation in COPD, the interpretation of the results of the London Chest Activity of Daily Living (LCADL) scale is limited because a lack of a valid cutoff point to this scale. For that, this study sought to compare the functional status between men and women with COPD; and propose a cutoff point for LCADL capable of discriminating the prognosis of these individuals.

METHODS

A sample of 138 subjects with moderate-severe COPD was evaluated by the LCADL. The percentage of the individual maximum score was used to obtain a cutoff point capable of discriminating patients with the worse prognosis according to the BODE Index. The cutoff point was also tested in an independent sample (n = 70).

RESULTS

Regarding the total score, domestic and leisure domains of the LCADL, men had better scores than women (P ≤ 0.01). The cutoff point found was 37% (area under the curve = 0.70, 95% confidence interval = 0.60-0.80, sensitivity = 0.55 and specificity = 0.74). Individuals who scored ≥ 37% had a worse prognosis and level of physical activities of daily living than those who scored below (P ≤ 0.02).

CONCLUSION

When evaluated by the LCADL, men and women with COPD present difference in the functional status. The established cutoff point (37%) adequately discriminates individuals regarding the prognosis, contributing to improve the interpretation capacity of the LCADL.

Relative contribution of various chronic diseases and multi-morbidity to potential disability among Dutch elderly

Background

The amount of time spent living with disease greatly influences elderly people’s wellbeing, disability and healthcare costs, but differs by disease, age and sex.

Methods

We assessed how various single and combined diseases differentially affect life years spent living with disease in Dutch elderly men and women (65+) over their remaining life course. Multistate life table calculations were applied to age and sex-specific disease prevalence, incidence and death rates for the Netherlands in 2007. We distinguished congestive heart failure, coronary heart disease (CHD), breast and prostate cancer, colon cancer, lung cancer, diabetes, COPD, stroke, dementia and osteoarthritis.

Results

Across ages 65, 70, 75, 80 and 85, CHD caused the most time spent living with disease for Dutch men (from 7.6 years at age 65 to 3.7 years at age 85) and osteoarthritis for Dutch women (from 11.7 years at age 65 to 4.8 years at age 85). Of the various co-occurrences of disease, the combination of diabetes and osteoarthritis led to the most time spent living with disease, for both men (from 11.2 years at age 65 to 4.9 -years at age 85) and women (from 14.2 years at age 65 to 6.0 years at age 85).

Conclusions

Specific single and multi-morbid diseases affect men and women differently at different phases in the life course in terms of the time spent living with disease, and consequently, their potential disability. Timely sex and age-specific interventions targeting prevention of the single and combined diseases identified could reduce healthcare costs and increase wellbeing in elderly people.

Social Network Types, Health, and Health-Care Use Among South Korean Older Adults

This study examines the associations among social network types, multiple health conditions, and various health-care use. Data came from the 2006 and 2008 wave of the Korean Longitudinal Study of Aging. A two-step cluster analytical approach was used to identify social network types. Regression models determined associations between social network types, health changes, and health-care use, including checkups, outpatient service, traditional medicine use, and hospitalization. Four social network types (restricted, couple focused, friend, and diverse) were found. Compared with the restricted type, individuals in the couple-focused type were more likely to use traditional medicine and outpatient care; members in the diverse type were more likely to use traditional medicine. The interaction model revealed varying associations between health change and social network on health-care use. Findings reveal the culturally contextualized association among multiple health conditions and how social network type moderates the relationship with health-care use.

Predictors of functional disability with focus on activities of daily living: A community based follow-up study in older adults in India

BACKGROUND

Disability in activities of daily living is a growing concern among older populations all over the world. India has one of the rapidly ageing populations and predicted burden of functional disability is higher for Indian older adults as compared to other ageing Asian countries.

METHODS

Total 1140 aged 60 years and over participated in a baseline study. 560 of them participated in the prospective cohort study conducted in the city of Pune, India. An interview and functional assessment using a questionnaire and Pune-FAAT tool was carried out in 2013-14. Binary logistic regression was used to obtain the factors that increased the odds of having ADL disability at follow-up.

RESULTS

The mean age of the study population was 69.73±5.48years. Squatting, walking and climbing functions were affected significantly. Total 376 participants (67.1%) reported difficulties and/or disability in performing activities of daily living (ADL) at follow-up. Hospitalization (OR=3.6; 95% CI: 1.9-6.7), being female (OR=2.3; 95% CI: 1.5-3.5), presence of two or more chronic diseases (OR=1.7; 95% CI: 1.1-2.7), experience of memory loss (OR=1.9; 95% CI: 1.2-3.0) and feeling of loneliness (OR=2.3; 95% CI: 1.0-5.3) increased the odds of being in the "With disability" group at follow-up. Apart from this, self-rated health and self-reported depression were associated with limitations in ADL.

CONCLUSION

Hospitalization and being female appeared to be the most significant risk factors for disability in urban older adults in India. Rehabilitation services after hospitalization, physical exercise, effective control on chronic illness, and social participation to reduce loneliness is recommended.

Preventing Loss of Basic Activities of Daily Living and Instrumental Activities of Daily Living in Elderly: Identification of Individual Risk Factors in a Holistic Perspective

This study investigated the association between physical functioning and activities of daily living (ADL) of elderly people, taking into account the role of cognitive, psychological, and social factors. We administered physical, cognitive, psychological, and social instruments to investigate the level of basic and instrumental activities of daily living (BADL and IADL). The analysis showed that physical functioning was the only individual factor that was significantly linked with the level of BADL and IADL. This study underlines that physical functioning is the main individual characteristic directly associated with the level of BADL and IADL in old age.

Impact of multimorbidity on disability and quality of life in the Spanish older population

Background

Population aging is closely related to high prevalence of chronic conditions in developed countries. In this context, health care policies aim to increase life span cost-effectively while maintaining quality of life and functional ability. There is still, however, a need for further understanding of how chronic conditions affect these health aspects. The aim of this paper is to assess the individual and combined impact of chronic physical and mental conditions on quality of life and disability in Spain, and secondly to show gender trends.

Methods

Cross-sectional data were collected from the COURAGE study. A total of 3,625 participants over 50 years old from Spain were included. Crude and adjusted multiple linear regressions were conducted to detect associations between individual chronic conditions and disability, and between chronic conditions and quality of life. Separate models were used to assess the influence of the number of diseases on the same variables. Additional analogous regressions were performed for males and females.

Results

All chronic conditions except hypertension were statistically associated with poor results in quality of life and disability. Depression, anxiety and stroke were found to have the greatest impact on outcomes. The number of chronic conditions was associated with substantially lower quality of life [β for 4+ diseases: −18.10 (−20.95,−15.25)] and greater disability [β for 4+ diseases: 27.64 (24.99,30.29]. In general, women suffered from higher rates of multimorbidity and poorer results in quality of life and disability.

Conclusions

Chronic conditions impact greatly on quality of life and disability in the older Spanish population, especially when co-occurring diseases are added. Multimorbidity considerations should be a priority in the development of future health policies focused on quality of life and disability. Further studies would benefit from an expanded selection of diseases. Policies should also deal with gender idiosyncrasy in certain cases.

Renal function and decline in functional capacity in older adults

BACKGROUND

longitudinal relationship between renal function, disability and mortality has not been evaluated.

OBJECTIVE

we investigated the temporal association between renal function and disability, and aimed to identify the influence of disability on mortality according to renal function in a cohort of older Koreans.

DESIGN/SETTING

Korean Longitudinal Study on Health and Aging is a prospective, population-based cohort.

SUBJECTS

community-dwelling Koreans ≥65 years of age.

MAIN OUTCOME MEASURES

Korean version of activities of daily living (ADL), Instrumental activities of daily living (IADL) and all-cause mortality.

RESULTS

a total of 984 participants were followed for 5 years with a 70.9% participation rate. The participants were categorized into three groups according to their baseline estimated glomerular filtration rates (eGFRs) (Group I, ≥60; Group II, 45-59; and Group III, <45 ml/min/1.73 m(2)). Baseline eGFR was higher in participants who maintained functional status compared with participants who died or had disability at follow-up examination. The incidence of ADL/IADL decline was 13, 12.5 and 29.5% in participants who showed improvement, no change, and decline in renal function, respectively (P = 0.01). The hazard ratio for mortality in the subgroup with IADL disability was 1.87 (95% CI: 1.10-3.20, P = 0.022) in Group I, and 2.53 (95% CI: 1.57-4.09, P<0.001) in Groups II and III after adjustment.

CONCLUSIONS

impaired renal function was related to disability and ADL/IADL decline. The effect of ADL/IADL disability on mortality was more prominent in participants with impaired eGFR.

Influência de gênero, idade e renda sobre o bem-estar de idosos cuidadores e não cuidadores

OBJETIVOS: Comparar idosos cuidadores e não cuidadores quanto às condições de saúde, psicossociais e de desempenho funcional e conhecer a influência das variáveis socioeconômicas sobre estes grupos. MÉTODO: Estudo envolvendo idosos residentes de três cidades brasileiras - Parnaíba-PI, Campinas-SP e Ivoti-RS - com base nos dados do estudo FIBRA. A amostra foi composta de 676 idosos, 338 cuidadores e 338 não cuidadores. Os cuidadores responderam afirmativamente a duas questões sobre a prestação de cuidado no Elders Life Stress Inventory. Os instrumentos utilizados foram: versões brasileiras da Geriatric Depression Scale, da Interpersonal Support Evaluation List, da escala de atividades instrumentais de vida diária (AIVD), de 13 itens de atividades avançadas de vida diária e escala de satisfação com a vida. Foram aplicadas questões de autorrelato sobre idade, gênero, renda familiar, número de doenças e fadiga. RESULTADOS: Os cuidadores compuseram 29,7% da amostra. A tarefa de cuidar era mais frequente entre as mulheres (65,7%), os idosos de 65 a 74 anos e os de menor renda familiar. Houve frequência maior de queixa de insônia entre os cuidadores comparados com os não cuidadores (p=0,013). Para os grupos, ser mais pobre significou maior frequência de insônia e de dependência em AIVD, além de mais sintomas depressivos entre os cuidadores (p=0,24). As mulheres eram as mais doentes e os homens os mais isolados socialmente. Os cuidadores mais velhos reportaram maior grau de dependência em AIVD (p=0,015). CONCLUSÃO: Circunstâncias socioeconômicas podem contribuir para desfechos negativos sobre as condições de saúde física e bem-estar psicológico, especialmente entre os cuidadores.

Bedrest and sarcopenia

PURPOSE OF REVIEW

The primary focus of this review is to characterize the physiological elements of sarcopenia. In addition, we will also describe the impact of bedrest on sarcopenia and how various countermeasures may be able to offset the deleterious clinical consequences of unanticipated bedrest or hospitalization. It is well known that the aging process presents many challenges to the maintenance of overall health. With the increasing rate of obesity and the potentially simultaneous development of sarcopenia, bedrest presents a difficult clinical challenge to the elderly individual.

RECENT FINDINGS

The etiology of accelerated sarcopenia has been described as a syndrome. The characteristics of this syndrome include combined alterations in neuromuscular control and muscle protein synthesis that increase the risk of morbidity and mortality in the elderly population. Moreover, the acute onset of bedrest-induced insulin resistance may further complicate the nutritionally derived maintenance of muscle mass and physical function.

SUMMARY

Even though many questions remain unresolved concerning the optimal clinical management of elderly individuals who undergo unanticipated bedrest, the supplementation of essential amino acids has shown promise as a therapeutic strategy to minimize the detrimental influence of hospitalization in the elderly. In turn, this nutritional adjunctive therapy may reduce the length of stay and the likelihood of repeated hospitalization.
