When do older adults become "disabled"? Social and health antecedents of perceived disability in a panel study of the oldest old

Elevated Risk of Dementia Diagnosis in Older Adults with Low Frequencies and Durations of Social Conversation

Background

Social networks and social participation have protective effects on cognitive function maintenance and Alzheimer's disease and general dementia development.

Objective

We aimed to investigate the association between conversations and dementia incidence in older adults.

Methods

This longitudinal prospective cohort study used population data from the National Center for Geriatric and Gerontology-Study of Geriatric Syndromes (NCGG-SGS) from September 2015 to February 2017. The database included 4,167 individuals in Japan aged ≥60 years who were generally healthy and without major cognitive impairment. Participants were classified into two groups according to six daily conversation measures at baseline. The conversation index was calculated as a composite score for these measures. Participants were tracked monthly over 60 months for new-onset dementia.

Results

Data from 2,531 participants were analyzed (72.7±6.7 years; range: 60-96 years). Dementia incidence per 1,000 person-years was 15.7 (95% confidence interval, 13.6-18.1). The Youden index determined the cut-off point for dementia incidence, with a conversation index of 16/17 points. The low conversation group included more participants with new-onset dementia. Cox proportional hazards regression crude models showed remarkable relationships between dementia onset and specific conversation measurements, including conversation index. According to the Cox regression adjusted model, the cut-off point of the conversation index showed only a remarkable relationship with dementia onset.

Conclusions

Dementia risk was extensively associated with low daily conversation statuses. The assessment of conversational factors may be useful as a risk indicator for the development of Alzheimer's disease and general dementia.

Relationship between frailty and loneliness among community-dwelling Turkish older people

BACKGROUND

The scarcity of concrete data between loneliness and frailty was found and to fill this gap, the present study aimed to examine the relationship between frailty and loneliness in elderly individuals. The study was conducted to determine the relationship between loneliness and frailty in individuals aged 65 and over.

METHOD

The study had a cross-sectional descriptive correlational design. The study group consisted of 527 volunteers aged 65 and over who applied to six family health centres between 15.03.2019 and 15.05.2019 and met the inclusion criteria. The Information Form, Tilburg Frailty Indicator (TFI), and Loneliness Scale for the Elderly (LSE) were used to collect the study data.

RESULTS

It was found that the mean age of individuals with frailty (69.67 ± 4.38) was found to be higher at a statistically significant level than those without frailty (67.83 ± 3.07) (t = -5.390; P = 0.001). It was found that a total of 89.1% of those who stated they had a serious disease (χ²  = 69.688, P < 0.001) and 68.9% (χ²  = 24.315, P < 0.001) of those who had a serious disease in a loved one were statistically frail. The mean total score obtained in the LSE was 12.702 ± 5.76 and it was statistically significant at a high level (t = -12.225, P < 0.001) There was a statistically significant relationship between the TFI and its subscales, and the LSE and subscale scores of the individuals who participated in the study.

CONCLUSION

A positive and significant relationship was detected between all subscales of loneliness and frailty; therefore, it can be argued that the negativity in one negatively affects the other. According to these results, it can be recommended to conduct screening and intervention programs to prevent frailty and loneliness in individuals aged 65 and over and prioritise the risk factors that were found in the present study.

Longitudinal qualitative study of living with neurogenic claudication

OBJECTIVES

Neurogenic claudication (NC) causes pain and reduced mobility, particularly in older people, and can negatively affect mental and social well-being, so limiting successful ageing. This qualitative study explored how people with NC changed over 12 months.

DESIGN

A longitudinal qualitative study using semi-structured interviews.

SETTING

Participants were recruited from a UK clinical trial of a physiotherapy intervention for NC.

PARTICIPANTS

Interviews were undertaken at baseline, 1 month after receiving any intervention and at 12 months. We analysed 30 sets of three interviews.

RESULTS

Interview data were summarised for each time point into biopsychosocial domains: pain, mobility and activities of daily living, psychological impact, and social and recreational participation. Through comparative analysis we explored participant trajectories over time.Progressive improvement in at least one domain was experienced by 13 participants, but there was variability in trajectories with early improvements that remained the same, transient changes and no change also commonly observed.Eleven participants described co-present improvement trajectories in all domains. Three participants described co-present improvement in all domains except participation; one had never stopped their participation and two had unattainable expectations. Five participants described co-present improvement in one domain and deterioration in another and 14 participants described co-present no change in one domain and change in another.There was evidence of interaction between domains; for example, improved mobility led to improved participation and for some participants, specific factors influenced change. Of the 15 participants who experienced improved participation, 10 reported improvements in all other domains and five participants did not; for two, pain did not prevent participation, one used a walking aid and two had a positive psychological outlook.

CONCLUSION

The daily lived experiences of older adults with NC are variable and include interaction between biopsychosocial domains. Therapist understanding of these trajectories and their interactions may help to provide personalised therapy TRIAL REGISTRATION NUMBER: ISRCTN12698674.

Leashes, Litterboxes, and Lifelines: Exploring Volunteer-Based Pet Care Assistance Programs for Older Adults

At the convergence of population aging and pet-ownership, community stakeholders are well-positioned to support older adults' relationships with companion animals through age-related transitions in health and living arrangements. In this study's setting, a volunteer-based pet care assistance program launched in 2017 to provide practical assistance with pet care for socially disadvantaged, community-dwelling older adults. This case study explored the impacts and feasibility of this and similar programs via (i) an Internet-based environmental scan to compare similar programs and (ii) qualitative interviews with a sampling of diverse community stakeholders (n = 9). A small number of comparable international programs (n = 16) were found. Among these, programs were delivered using a range of funding models; fewer than half involved collaborations across human social services and animal welfare sectors; and none addressed all dimensions of support offered by our local program. Analysis of qualitative interviews highlighted five major themes confirming the value of the volunteer-based approach and the importance of cross-sectoral collaborations in addressing older adults' under-recognized pet care-related needs. Taken together, the findings confirmed the effectiveness of our local program model. Collaborative, cross-sectoral programs that target both human and companion animal well-being hold promise to reduce barriers to pet ownership that many disadvantaged older adults face. This unique approach leverages the health-promoting potential of human-animal relationships in ways that enhance quality of life for individuals, animal welfare, and age-friendliness of communities.

Osteosarcopenia, the co-existence of osteoporosis and sarcopenia, is associated with social frailty in older adults

BACKGROUND

Osteosarcopenia is a newly described, aging-associated condition. Social frailty is an important condition whose prevalence may have risen by physical distancing during the coronavirus disease 2019 pandemic. However, the relationship between these two remains unclear.

AIMS

To examine the association between osteosarcopenia and social frailty.

METHODS

This cross-sectional study was conducted using data from outpatients visiting general geriatric hospital frailty clinics. Bone mineral density (BMD) and muscle mass were measured using dual X-ray absorptiometry. Osteoporosis was defined as a BMD of < 70% of the young adult mean, according to the Japan Osteoporosis Society. Sarcopenia was diagnosed as per the Asian Working Group for Sarcopenia 2019 recommendation. Osteosarcopenia was defined as the co-existence of osteoporosis and sarcopenia. We defined social frailty using a questionnaire comprising four items: general resources, social resources, social behavior, and basic social needs. Ordinal logistic regression analysis was performed with social frailty status and osteosarcopenia as the dependent and independent variables, respectively.

RESULTS

We included 495 patients (mean age = 76.5 ± 7.2 years) in the analysis; of these, 58.2% were robust and 17.2%, 13.5%, and 11.1% had osteoporosis alone, sarcopenia alone, and osteosarcopenia, respectively. Social frailty prevalence increased stepwise from 8.0% in robust patients to 11.8%, 17.9%, and 29.1% among those with osteoporosis alone, sarcopenia alone, and osteosarcopenia, respectively (P < 0.001). Logistic regression analysis revealed that only osteosarcopenia was significantly associated with social frailty (pooled odds ratio: 2.117; 95% confidence interval: 1.104-4.213).

DISCUSSION

Comprehensive assessment of osteosarcopenia and social frailty is needed for disability prevention in older adults.

Can Social Resources Explain the Limitations in the Activities of Daily Living of Older Adults Classified by the Phenotype of Physical Frailty?

The objective is to investigate the mediating roles of living alone and personal network in the relationship between physical frailty and activities of daily living (ADL) limitations among older adults. 2271 individuals were classified as vulnerable (pre-frail or frail) or robust. Mediating variables were living alone and personal network. Katz Index and Lawton-Brody scale were used to assess ADL. Mediating effects were analyzed with beta coefficients from linear regression models using the bootstrapping method. Mediation analysis showed significant mediating effects of living alone (β = .011; 95% CI = .004; .018) and personal network (β = .005; 95% CI = .001; .010) on the relationship between physical frailty and basic ADL limitations. Mediation effects of living alone and personal network on the relationship between physical frailty and instrumental ADL limitations were β = -.074 (95% CI=-.101; -.046) and β = -.044 (95% CI = -.076; -.020), respectively. Physically vulnerable older adults who lived alone or had poor personal network were more dependent on basic and instrumental ADL.

The impact of long-term conditions on disability-free life expectancy: A systematic review

Although leading causes of death are regularly reported, there is disagreement on which long-term conditions (LTCs) reduce disability-free life expectancy (DFLE) the most. We aimed to estimate increases in DFLE associated with elimination of a range of LTCs. This is a comprehensive systematic review and meta-analysis of studies assessing the effects of LTCs on health expectancy (HE). MEDLINE, Embase, HMIC, Science Citation Index, and Social Science Citation Index were systematically searched for studies published in English from July 2007 to July 2020 with updated searches from inception to April 8, 2021. LTCs considered included: arthritis, diabetes, cardiovascular disease including stroke and peripheral vascular disease, respiratory disease, visual and hearing impairment, dementia, cognitive impairment, depression, cancer, and comorbidity. Studies were included if they estimated HE outcomes (disability-free, active or healthy life expectancy) at age 50 or older for individuals with and without the LTC. Study selection and quality assessment were undertaken by teams of independent reviewers. Meta-analysis was feasible if three or more studies assessed the impact of the same LTC on the same HE at the same age using comparable methods, with narrative syntheses for the remaining studies. Studies reporting Years of Life Lost (YLL), Years of Life with Disability (YLD) and Disability Adjusted Life Years (DALYs = YLL+YLD) were included but reported separately as incomparable with other HE outcomes (PROSPERO registration: CRD42020196049). Searches returned 6072 unique records, yielding 404 eligible for full text retrieval from which 30 DFLE-related and 7 DALY-related were eligible for inclusion. Thirteen studies reported a single condition, and 17 studies reported on more than one condition (two to nine LTCs). Only seven studies examined the impact of comorbidities. Random effects meta-analyses were feasible for a subgroup of studies examining diabetes (four studies) or respiratory diseases (three studies) on DFLE. From pooled results, individuals at age 65 without diabetes gain on average 2.28 years disability-free compared to those with diabetes (95% CI: 0.57-3.99, p<0.01, I2 = 96.7%), whilst individuals without respiratory diseases gain on average 1.47 years compared to those with respiratory diseases (95% CI: 0.77-2.17, p<0.01, I2 = 79.8%). Eliminating diabetes, stroke, hypertension or arthritis would result in compression of disability. Of the seven longitudinal studies assessing the impact of multiple LTCs, three found that stroke had the greatest effect on DFLE for both genders. This study is the first to systematically quantify the impact of LTCs on both HE and LE at a global level, to assess potential compression of disability. Diabetes, stroke, hypertension and arthritis had a greater effect on DFLE than LE and so elimination would result in compression of disability. Guidelines for reporting HE outcomes would assist data synthesis in the future, which would in turn aid public health policy.

Missing Pieces: Engaging Sociology of Disability in Medical Sociology

Medical sociologists and sociologists of disability study similar topics but, because of competing or conflicting theoretical paradigms, tend to arrive at different conclusions, engage with different audiences, and pursue different directions for social change. Despite diverging trajectories over the past 20 years, however, there remains clear potential overlap between both subfields in the study of disability and untapped opportunities for cross-fertilization. Our purpose here is to place these literatures in conversation with each other. Toward this end, we identify major themes in the last 20 years of medical sociology scholarship, gaps with regard to disability in those themes, and possibilities (including methodologies) we see at the intersection of medical sociology and the sociology of disability that could address these gaps.

The Landscape of Perception: Racial Differences in How Disability Is Viewed Among Older-Adult Cancer Survivors

This paper compares disability perceptions of Black with white older cancer survivors' to document racial disparities in these perceptions and the factors that contribute to them. The data are from a randomly selected tumor registry sample of 321 older adult cancer survivors from an NCI funded study. OLS regression models of disability perceptions, nested by race, examined the effects cancer and non-cancer health factors along with important covariates. Black older adult cancer survivors perceived themselves to be more disabled than did white survivors. Multivariate analyses showed a strong relationship between functional difficulties and disability perceptions for both Black and white survivors. However cancer-related factors such as continuing symptoms of the illness or treatment were relatively more important for Blacks. The findings suggest that race and cancer are both important factors in our understanding of disability in later life. These findings can then inform clinical best practices among minority older adults.

Old Overnight: Experiences of Age-Based Recommendations in Response to the COVID-19 Pandemic in Sweden

The Swedish response to the COVID-19 pandemic included age-based recommendations of voluntary quarantine specifically for those 70 years of age or older. This paper investigates the experiences of a sudden change of policy in the form of an age restriction that trumped the contemporary active aging ideal. A web-based qualitative survey was conducted in April 2020. Through manual coding of a total of 851 responses, six different ways of relating to the age-based recommendations were identified. The results show that age is not an unproblematic governing principle. Instead, in addition to protecting a vulnerable group, the age-based recommendation meant deprivation of previously assigned individual responsibility and, consequently, autonomy. It is shown how respondents handled this tension through varying degrees of compliance and resistance. Findings highlight the importance of continuously tracking the long-term consequences of age-based policy to avoid negative self-image and poorer health among older adults.

Association of functional limitations and disability with elder abuse in India: a cross-sectional study

Background

Globally, elder abuse is a common form of violence against the elderly. This study examines the association of disability and functional ability measures with elder abuse in India.

Methods

Cross-sectional data from the UNFPA’s ‘Building Knowledge Base on Population Ageing in India’ (BKPAI 2011) have been analysed. Bivariate and multivariate logistic regression analyses have been used to examine the association of measures of disability and functional ability with elder abuse/mistreatment.

Results

The overall prevalence of elder abuse in the study population is 11.4%. The prevalence of elder abuse experienced by study participants in the month before the survey is 6%. The prevalence of disability/functional ability increases the likelihood of elder abuse. Furthermore, the association between functional ability and abuse is stronger and consistent among the elderly who experienced abuse in the month preceding the survey. In addition, the association between disability and elder abuse is stronger in urban areas. Another observation is that gender introduces considerable disparities in the association of disability and functional ability measures with elder abuse. While elderly men with more than two disabilities are 1.85 times (95% CI: 1.23, 2.77, p < 0.003) more likely to experience abuse/mistreatment, women are 3.16 times (CI: 2.22, 4.49, p < .001) more exposed to it.

Conclusions

The results of this study suggest a significant association of disability and functional ability with elder abuse. The association differs considerably by place of residence and gender. Measures to improve the functional health of the elderly population and measures to protect the elderly with disability and functional limitations are important in preventing abuse/mistreatment in old age.

Implications of Mothers' Social Networks for Risky Infant Sleep Practices

OBJECTIVE

To describe the structure of networks in a cohort of mothers and to analyze associations of social network characteristics and norms with infant sleep practices.

STUDY DESIGN

We recruited a prospective cohort of mothers with infants <6 months of age from January 2015 to December 2016. Mothers completed a survey about their personal social networks and infant care practices. Latent class analysis identified unobserved network types. Binary statistics and path analysis were performed.

RESULTS

Overall, 402 mothers were surveyed. Latent class analysis identified 2 a priori unknown social network types: "exclusive" (restricted) and "expansive." Mothers who were black, younger, unmarried, less educated, and of lower socioeconomic status were more likely to have exclusive networks than expansive networks. Mothers with exclusive networks were more likely to be exposed to the norm of soft bedding (P = .002). Exposure to norms of non-supine infant placement, bedsharing, and soft bedding use within one's network was associated with engaging in these practices (P < .0001 for each). First-time mothers were more likely to pay attention to a non-supine norm and place infants in a non-supine position. Black mothers and first-time mothers were more likely to pay attention to the norm and use soft bedding.

CONCLUSIONS

Both the type of networks mothers have and the norms regarding infant sleep practices that circulate within these networks differed by race. Network norms were strongly associated with infant sleep practices and may partially explain the racial disparity therein.

Meeting Challenges of Late Life Disability Proactively

Discussions of disability in the gerontological and the disability studies literatures have seldom considered unique perspectives and needs of older adults. Disability has often been stigmatized and viewed as antithetical to successful aging. We call for expansion of prevailing paradigms of disability to address the resilience and continuing human potential of older adults living with disabilities. In addition to recognizing the environmental context of disability, we propose greater attention to adaptive potential of disabled older adults. We discuss 6 types of proactive adaptations that can contribute to empowerment, meaning, enhanced quality of life and psychological well-being among persons living with late-life onset disabilities. These include: (a) helping others, (b) planning for future care, (c) marshaling intergenerational support, (d) self-advocacy for responsive health care, (e) making environmental modifications to improve safety and comfort of the home, and (f) finding strength in spiritual pursuits. Enacting proactive adaptations can contribute to resilience in facing late life impairments and functional limitations. Such efforts can complement utilization of services and obtaining accommodations. Maintaining life satisfaction among older adults living with disabilities also involves focus on transcendent personal goals and acceptance of an altered self. We note how a more integrative view of medical and social dimensions of disability, infused with concepts of human agency, contributes to rapprochement between alternative disciplinary orientations to late life disability. Without negating society’s important responsibilities for accommodating to needs of older adults living with disability, we reaffirm their potential for greater control and self-determination through proactive adaptations.

Culture, Ageing and the Construction of Pain

In this paper, the authors seek to discuss some of the complexities involved in cross-cultural working in relation to the communication and management of pain in older people. Specifically, the paper addresses the culture construction of ageing and how pain is often constructed as a natural part of ageing. The authors also suggest that with the rise of the ideology of active-ageing, many older people who are disabled or living in chronic pain, may feel a moral imperative to hide pain and ill-health. The discussion extends into looking at the impact of culture and the communication of pain, including specific idioms of distress, somaticize and the lay-management of pain through stoicism. The literature utilised in this paper was based on a thematic review, exploring the cultural dimensions of health, illness and pain in old age. The review also drew on the authors' previous publications, as well as their extensive community research experience working with ethnic minority communities.

Too many 'false dichotomies'? Investigating the division between ageing and disability in social care services in Ireland: A study with statutory and non-statutory organisations

Initiatives that bridge the fields of ageing and disability are considered critical internationally but to be limited in practice. Taking Ireland as a case, and focusing on social care, this article reports on a study investigating the separate organization of older people's and disability services as perceived by those working in policy-making, service provision and advocacy. In Ireland, as in many countries, social care is administered separately for disabled people and older people. Perceptions of those working in social care are thought to play a role in successful boundary-crossing initiatives. This study suggests that while participants often perceived the administrative and funding boundary between the fields of ageing and disability as illogical, inflexible, and not delivering person-centred care or support, the divide between the two sectors is underpinned by conceptual issues, including the lack of a concept of disability with ageing. The article argues that ways are needed of articulating what it is to experience disability in older age that are shared between older people's and disability sectors. It discusses bio-psychosocial models of disability as a means of doing so, one that avoids a return to an equation between older age and impairment, disability or decline. It concludes that more interrogation is needed of the separate philosophical underpinnings of disability and older people's sectors, argues for greater linkages between the two fields and for more exploration of social constructions of the experience of disability in later life.

Factors Affecting Perceptions of Disability and Self-Rated Health Among Older Adult, Long-Term Cancer Survivors

OBJECTIVE

This article examines the relative importance of cancer-related and noncancer illness factors as they predict the health quality of life among older adult, long-term cancer survivors. Specifically, it examines the effects that continuing cancer symptoms and comorbidities have on functional difficulties and how they in turn affect perceptions of disability and self-rated health.

METHOD

Data from an National Cancer Institute (NCI)-funded, tumor registry-based 10-year study of 321 older adult (age 60+), long-term (5+years post diagnosis) survivors of breast colorectal and prostate cancer are examined using regression analyses.

RESULTS

The analyses documented the independent effects of both cancer-related and age-related health factors as they contribute to explaining functional difficulties, perceptions of disability and self-rated health. Gender and racial differences in health quality of life were also identified.

DISCUSSION

The findings suggest that geriatricians, geriatric nurses, and clinical gerontologists who work with cancer survivorsneed to be aware of the ways in which both cancer and noncancer illness factors work together in producing threats to health quality of life through the extent and nature of functional impairments.

Transitions in Living Arrangements Among Older Mexican Americans

This study examines the transition from independent living to a coresidential living arrangement across the late life course among older unmarried (i.e., widowed, divorced/separated, and single) Mexican Americans. Using 18 years' worth of panel data from the Hispanic Established Populations for the Epidemiologic Study of the Elderly, event history analyses revealed that age at migration, physical disability, and cognitive impairment were strong predictors of the transition to a coresidential living arrangement. Importantly, a decline in physical and cognitive abilities heightened the risk of transition to a coresidential living arrangement, net of time-variant measures of disability and impairment. These findings provide evidence for incorporating a dynamic approach to examining living arrangements across the late life course for Mexican-origin Hispanics living in the United States, with implications for policy and service providers.

Perceived resident-facility fit and sense of control in assisted living

The concept of resident-facility fit has largely been used to illustrate whether a residential care facility and a resident are together able to meet requirements set by only the hampering functional abilities of the latter. The purpose of this paper is to study how assisted living residents perceive resident-facility fit. The data were gathered ethnographically from both observations and resident interviews in a sheltered home in Finland during 2013-2014. Perceived resident-facility fit is based on several relational factors that connect to both the residents as individuals and their surroundings. This fit seems also to be partly conditional and indeed depends on residents' trust in having their own potential to act. Good resident-facility fit results in feeling at home in a facility, whereas poor fit can even result in residents' feeling imprisoned. Care providers can thus utilize our results to affirm residents' quality of life in residential facilities.

Social support and cognitive functioning as resources for elderly persons with chronic arthritis pain

OBJECTIVE

Arthritis pain and depression are prevalent physical and psychological disorders in late life and co-occur frequently. We explored the stability and covariation of arthritis pain and depressive symptoms. We also addressed the influence of cognitive functioning and social support on the relationship between pain and depressive symptoms among community-dwelling older individuals.

METHOD

This longitudinal study utilized a sample of 299 residents of Florida retirement communities who participated in a long-term panel study using yearly assessments across 4 years. Using multilevel modeling, we modeled the individual differences as well as stability in arthritis pain and depressive symptoms simultaneously. Further, we tested the role of cognitive functioning and social support in the association between arthritis pain and depressive symptoms.

RESULTS

We found substantial within-person variation in both pain and depressive symptoms (between 58% and 65%) across 4 years even after controlling for a time effect. After controlling for arthritis pain, persons with higher social support and higher cognitive functioning reported lower levels of depressive symptoms.

DISCUSSION

Findings suggest that fluctuations in pain and depressive symptoms are common for older adults. Furthermore, social support and intact cognitive functioning may serve as useful resources, as they buffer the negative impact of arthritis pain on depressive symptoms.

Mediation analysis of relationships between chronic inflammation and quality of life in older adults

Background

This article summarizes exploratory analyses of relationships between chronic inflammation, its physical consequences, and quality of life (QoL). It summarizes key findings from preliminary analyses, and contextualizes these results with extant sociomedical literature to recommend directions for future research.

Methods

Cross-sectional data from the National Social Life, Health, and Aging Project (NSHAP) were used to explore these relationships. Inflammation was assessed via the biomarker C-reactive protein (CRP). We examined associations between CRP levels and two different domains of QoL: happiness with life in general and happiness with intimate relationships. We used ordinal logistic regression with companion OLS models and Sobel-Goodman tests to assess potential mediation, and also conducted a variety of sensitivity analyses.

Results

Findings suggest that mediation pathways for the overall association between chronic inflammation and QoL may differ markedly across particular outcome constructs. Specifically, it shows mediation potential for the clinical sequelae of chronic inflammation in frameworks using happiness as an outcome measure, but not in those using relationship satisfaction. Disability appears to mediate the effect of inflammation by 27 %; chronic pain appears to exert a similar mediation effect of 21 %.

Conclusions

Pain and disability linked to chronic inflammation appear to play a small but significant mediating role in the overall reduction in QoL observed among older adults with biomarker evidence of chronic inflammation. We note that these patterns are best framed as dynamic elements of a complex causal fabric, rather than powerful determinants that override other factors contributing to QoL. Hypotheses for further exploration using longitudinal data from the NSHAP are thus offered, pending availability of Wave III data in future years.

Depression and its association with functional status and physical activity in the elderly in Karachi, Pakistan

OBJECTIVE

The aim of the study was to determine the functional status and level of physical activity and their association with depression in the elderly population (age 60 and above) in Karachi, Pakistan.

METHODS

This was a cross-sectional study. Subjects were recruited through multi-stage cluster sampling technique. Questionnaire-based interviews were conducted from July to September 2008. Functional status and physical activity were assessed using activities of daily living (ADL) and physical activity questionnaires, respectively. Depression was evaluated using the 15-item geriatric depression scale (GDS).

RESULTS

Both mean ADL score (9.9±0.2 vs. 9.6±0.2) as well as time spent in physical activity/week (377.3±26.9min vs. 251.7±15.4min) was higher in men than women, respectively. Subjects spending more than 310min (>5.2h) per week in physical activity were 60% less likely to be depressed compared to those who spent less than 120min (<2h) per week (Adjusted OR=0.4, 95% CI=0.2-0.7). A one unit increase in ADL score showed a 10% decrease in depression after adjusting for other variables (Adjusted OR=0.9, 95% CI=0.8-0.9).

CONCLUSIONS

We found a strong association between depression and time spent in physical activities as well as activities of daily living. Our results indicate the potentially important positive role of higher functional status and physical activity in prevention of depression in the elderly in Karachi.

Religious involvement and readiness to confirm reported physical disability

This investigation examines the influence of religious involvement on likelihood of verifying previously reported disability, net of current activity difficulty and self-rated health. It compares African American and white community-dwelling adults confirming (N = 348) and not confirming (N = 164) activity limitations. Logistic regressions show service attendance negatively associated with disability perception only among African Americans. For whites, use of beliefs in coping mitigates against confirmation of disability. Observed associations are conditioned by socioeconomic status and gender. These results underscore the importance of social context, as well as multidimensional religiosity, in understanding the health and disability implications of religiousness.

Functional capability and violence situations against the elderly

Objective To verify whether there is a connection between the functional capacity of the elderly and the presence of violent situations in their daily lives. Methods A population-based cross-sectional study developed with 237 elderly individuals. Standard and validated research instruments were used. Results Mean age of 70.25 years (standard deviation of 6.94), 69% were female, 76% were independent in basic activities of daily living and 54% had a partial dependence on at least one instrumental activity. The most prevalent violence was psychological and the relation between being dependent on basic activities of daily living and suffering physical violence was statistically significant. Conclusion When the elderly needs assistance to perform self-care activities, there is a greater chance of exposure to a situation of abuse, such as physical violence.

Social vulnerability from a social ecology perspective: a cohort study of older adults from the National Population Health Survey of Canada

Background

Numerous social factors, generally studied in isolation, have been associated with older adults’ health. Even so, older people’s social circumstances are complex and an approach which embraces this complexity is desirable. Here we investigate many social factors in relation to one another and to survival among older adults using a social ecology perspective to measure social vulnerability among older adults.

Methods

2740 adults aged 65 and older were followed for ten years in the Canadian National Population Health Survey (NPHS). Twenty-three individual-level social variables were drawn from the 1994 NPHS and five Enumeration Area (EA)-level variables were abstracted from the 1996 Canadian Census using postal code linkage. Principal Component Analysis (PCA) was used to identify dimensions of social vulnerability. All social variables were summed to create a social vulnerability index which was studied in relation to ten-year mortality.

Results

The PCA was limited by low variance (47%) explained by emergent factors. Seven dimensions of social vulnerability emerged in the most robust, yet limited, model: social support, engagement, living situation, self-esteem, sense of control, relations with others and contextual socio-economic status. These dimensions showed complex inter-relationships and were situated within a social ecology framework, considering spheres of influence from the individual through to group, neighbourhood and broader societal levels. Adjusting for age, sex, and frailty, increasing social vulnerability measured using the cumulative social vulnerability index was associated with increased risk of mortality over ten years in a Cox regression model (HR 1.04, 95% CI:1.01-1.07, p = 0.01).

Conclusions

Social vulnerability has important independent influence on older adults’ health though relationships between contributing variables are complex and do not lend themselves well to fragmentation into a small number of discrete factors. A social ecology perspective provides a candidate framework for further study of social vulnerability among older adults.

Perceived Stigma Among People With Chronic Health Conditions

Objectives:

This study addresses whether age, functional limitation and other stressor exposure, and psychosocial coping resources influence variation in perceived stigma and the form this influence takes (i.e., independent and/or interdependent).

Methods:

Using data from two waves of a large community study of adults (age 20–93) with chronic health conditions ( n = 417), a residual change regression analysis considers direct and moderating factors influencing perceived stigma over a 3-year period.

Results:

Age, functional limitation, the experience of discrimination, and self-esteem independently account for variation in perceived stigma. Moderation tests reveal that age is associated with a greater increase in stigma in the context of greater functional limitation and increases in limitation. Functional limitation and stressor exposure are also associated with declines in stigma in the context of greater mastery and self-esteem.

Discussion:

Multiple processes bear on perceived stigma among people with chronic health conditions. Implications for stigma and stress research are discussed.

Antecedents of self-regulation in driving among older drivers

Maintaining quality of life and wellbeing into advanced age is a major challenge to societies. Driving is one factor contributing to an ageing individual's independence. Understanding antecedents of driving-related self-regulation is important for designing interventions to preserve safe driving in old age. This paper reports on a study that investigated factors associated with two forms of self-regulation in driving (SRD) – avoidance of difficult driving conditions and voluntary cessation of driving – in a sample of 860 Israeli drivers aged 70 and over. We examined roles of health, vision, driving experience, driving-related self-efficacy (DRSE) and global self-esteem in SRD. Health and DRSE had direct effects on SRD, and effects of vision and driving experience were mediated by DRSE. Participants who had ceased driving were older, with poorer vision and health, and less driving confidence and experience than active drivers. Statistical analyses demonstrated that SRD is affected by a reduced sense of confidence due to an initial lower level of driving experience, compounded by deteriorating vision, and that older drivers are sensitive to factors affecting their ability to drive safely. Our results demonstrate that older drivers tend to self-regulate their driving. Programmes for older adults can be introduced for diagnosing driving capabilities, improving skills and confidence, and/or helping to develop self-regulation habits of avoiding driving in difficult conditions, and assisting drivers who must adjust to driving cessation.

Altruism, helping, and volunteering: pathways to well-being in late life

OBJECTIVE

We examined the influence of prosocial orientations including altruism, volunteering, and informal helping on positive and negative well-being outcomes among retirement community dwelling elders.

METHOD

We utilize data from 2 waves, 3 years apart, of a panel study of successful aging (N = 585). Psychosocial well-being outcomes measured include life satisfaction, positive affect, negative affect, and depressive symptomatology.

RESULTS

Ordinal logistic regression results indicate that altruistic attitudes, volunteering, and informal helping behaviors make unique contributions to the maintenance of life satisfaction, positive affect and other well being outcomes considered in this research. Predictors explain variance primarily in the positive indicators of psychological well-being, but are not significantly associated with the negative outcomes. Female gender and functional limitations are also associated with diminished psychological well-being.

DISCUSSION

Our findings underscore the value of altruistic attitudes as important additional predictors, along with prosocial behaviors in fostering life satisfaction and positive affect in old age.

Rule-based modeling of chronic disease epidemiology: elderly depression as an illustration

BACKGROUND

Rule-based Modeling (RBM) is a computer simulation modeling methodology already used to model infectious diseases. Extending this technique to the assessment of chronic diseases, mixing quantitative and qualitative data appear to be a promising alternative to classical methods. Elderly depression reveals an important source of comorbidities. Yet, the intertwined relationship between late-life events and the social support of the elderly person remains difficult to capture. We illustrate the usefulness of RBM in modeling chronic diseases using the example of elderly depression in Belgium.

METHODS

We defined a conceptual framework of interactions between late-life events and social support impacting elderly depression. This conceptual framework was underpinned by experts' opinions elicited through a questionnaire. Several scenarios were implemented successively to better mimic the real population, and to explore a treatment effect and a socio-economic distinction. The simulated patterns of depression by age were compared with empirical patterns retrieved from the Belgian Health Interview Survey.

RESULTS

Simulations were run using different groupings of experts' opinions on the parameters. The results indicate that the conceptual framework can reflect a realistic evolution of the prevalence of depression. Indeed, simulations combining the opinions of well-selected experts and a treatment effect showed no significant difference with the empirical pattern.

CONCLUSIONS

Our conceptual framework together with a quantification of parameters through elicited expert opinions improves the insights into possible dynamics driving elderly depression. While RBM does not require high-level skill in mathematics or computer programming, the whole implementation process provides a powerful tool to learn about complex chronic diseases, combining advantages of both quantitative and qualitative approaches.

The impact of transportation support on driving cessation among community-dwelling older adults

OBJECTIVES

This study longitudinally examines the impact of transportation support on driving cessation among community-dwelling older adults residing in retirement communities.

METHOD

Data came from 3 waves of the Florida Retirement Study (1990-1992), a population-based cohort study. Analysis was limited to participants who drove at baseline and were reinterviewed in 1992 (N = 636). Transportation support from a spouse, family members, friends/neighbors, agencies/organizations (e.g., church), or hired assistants was included. Discrete-time multivariate hazard models were estimated to examine the impact of transportation support on driving cessation while controlling for demographic and health characteristics.

RESULTS

Participants were more likely to stop driving if they had received at least some transportation support from friends/neighbors (Hazard Ratio = 2.49, p = .001) as compared with those with little or no support. Transportation support from organizations/agencies or hired assistants was also significantly associated with the likelihood of driving cessation, but only a small number of participants reported to have received such support. Receiving some or more transportation support from a spouse or family members did not have a statistically significant relationship with driving cessation.

DISCUSSION

The findings suggest that available nonkin transportation support, particularly support from peer friends, plays an important role in driving cessation for older adults living in retirement communities.

Proactive aging: a longitudinal study of stress, resources, agency, and well-being in late life

OBJECTIVES

Using the Proactivity Model of Successful Aging, we examined how internal and external resources contribute to the maintenance of psychological well-being and social activities among older adults who experience normative stressors of aging. Outcome variables in this study are collectively referred to as quality of life (QOL). We also examined the mediating role of proactive adaptations between internal and external resources and QOL indicators.

METHOD

Based on five annual interviews of a sample of 1000 community-dwelling older adults in Florida (effective N = 561), we tested the lagged effects of stressors on two indicators of QOL, four years later. In the full longitudinal model, using structural equations, we estimated the direct effects of internal and external resources on QOL, along with indirect effects through proactive adaptations.

RESULTS

Stressors negatively influenced QOL four years later. Internal and external resources led to better QOL four years later, both directly and indirectly through proactive adaptations of marshaling support and planning for the future.

CONCLUSION

These findings lend support to the Proactivity Model of Successful Aging by documenting the value of proactive adaptations (i.e., exercise, planning ahead, and marshaling support) as proximate influences on QOL outcomes (i.e., depressive symptomatology and social activities). Findings suggest that older adults can maintain successful aging even in the face of health-related and social stressors by invoking accumulated resources to deal actively with the challenges of aging.

Carpal tunnel surgery: patient preferences and predictors for satisfaction

Carpal tunnel syndrome is a debilitating disease of the upper extremity affecting patient function and quality of life. Surgical interventions have been developed that effectively treat this disease. However, there remains a subset of patients who are not fully satisfied with their outcome. Extensive investigation has been undertaken to analyze preoperative factors predictive of higher patient satisfaction. This review summarizes the role of unique patient characteristics and patient psychology, worker's compensation, patient demographics, certain clinical features, and patient preferences and expectations regarding patient satisfaction following carpal tunnel surgery. Understanding the complex nature of patient satisfaction will enable surgeons to indicate patients for surgical intervention better, provide appropriate preoperative counseling, and manage expectations postoperatively.

Voluntary and involuntary driving cessation in later life

This study explores the decision-making process of driving cessation in later life, with a focus on voluntariness. The sample included 83 former drivers from the Baltimore Epidemiologic Catchment Area Study. A majority of participants (83%) reportedly stopped driving by their own decision. However, many voluntary driving retirees reported external factors such as financial difficulty, anxiety about driving, or lack of access to a car as main reasons for driving cessation. These findings imply that distinction between voluntary and involuntary driving cessation is ambiguous and that factors beyond health status, including financial strain, play a role in the transition to non-driving.

The stigma of disability: Croatian experiences

PURPOSE

The aim of this paper is to get an insight into understanding the stigma of disability based on the experience and perception of people with disabilities and professionals who work with them.

METHODS

Qualitative research methods were used with two focus groups: one with people with disabilities (five participants) and other with professionals (seven participants). After data were collected, a qualitative content analysis was made.

RESULTS

The results indicated that participants perceived and experienced stigma of disability through intrinsic and extrinsic elements of stigmatization. The intrinsic elements refer to the feeling of being different as a result of negative attitudes, prejudices and stereotypes. The extrinsic elements derive from the relationship of the system towards people with disabilities: discrimination and labelling. Some of the major findings of this research are that the stigma of disability is shown through the inability of the people with disabilities to make their own decisions, the perception of the disability as the main feature of the person, the lack of criteria during education, perceiving disability as a precondition in choosing a partner and parental capability, parents' decision-making about their children's lives, overprotection and stigmatization in education and employment. Stigmatization leads to social exclusion and influences the quality of life.

CONCLUSION

The stigma of disability is manifested through the impossibility of realizing basic human rights, of living life independently and of taking equal part in a local community.

Independence through social networks: bridging potential among older women and men

OBJECTIVES

Most studies of older adults' social networks focus on their access to dense networks that yield access to social support. This paper documents gender differences in the extent to which older adults maintain a related, but distinct, form of social capital-bridging potential, which involves serving as a tie between two unconnected parties and thus boosts independence and control of everyday social life.

METHODS

I use egocentric social network data from a national sample of 3,005 older adults--collected in 2005-2006 by the National Social Life, Health, and Aging Project--to compare older men's and women's network bridging potential using multivariate regression analysis.

RESULTS

Older women are more likely than older men to have bridging potential in their networks-between both kin and non-kin contacts. These gender differences increase with age. Older women are also more likely to have network members who are not connected to or monopolized by their spouse or partner. Some, but not all, of these gender differences are due to the fact that older women have larger social networks and maintain more ties to people outside of the household.

DISCUSSION

These findings raise important questions about the relational advantages older women have over older men, including greater autonomy, and contradict stereotypes about women having more closely knit, kin-centered networks than men.

Examining the aging process through the stress-coping framework: application to driving cessation in later life

The aging process is marked by a series of transitions that influence multiple domains of well-being. One important transition for older adults is the process of driving cessation. Numerous studies have examined risk factors for driving cessation among older adults to identify at-risk older drivers for road safety. Recent research has focused on the consequences of driving cessation in later life for health and well-being. However, these reports have been largely empirical and are not drawn from a defined conceptual framework. Establishing a theoretical model of 'how driving cessation interacts with other processes and domains of aging' will promote synthesis of seemingly disparate findings and also link the empirical research on cessation to the broader field of gerontology. This article describes a conceptual model for articulating and examining the components of the driving cessation process based on the stress-coping paradigm. This model situates driving cessation within the context of exogenous stressors, individual vulnerabilities and coping strategies, and environmental hazards and buffers over the lifespan. This model could assist in guiding intervention strategies aimed at reducing premature driving cessation in older drivers with ameliorable impairments while assisting at-risk older drivers to reduce or stop driving in a less stressful way.

The epidemiology of specific phobia and subthreshold fear subtypes in a community-based sample of older adults

BACKGROUND

Specific phobias have received little attention among older adults. This study is aimed at determining the 12-month prevalence rates of fear subtypes in older adults with a full or subthreshold DSM diagnosis of specific phobia as well as to examine differences among these conditions according to health and health behavior characteristics potentially associated with the severity of anxious symptoms.

METHODS

Data came from a representative sample of community-dwelling older adults aged 65 years and older (N = 2784). Diagnoses were established by in-home semi-structured interviews. DSM-IV criteria for specific phobia were slightly modified in line with recommendations for DSM-V.

RESULTS

The 12-month prevalence rates of specific phobias and subthreshold fears were, respectively, 2.0 and 8.7%. More than half of the respondents with a specific phobia did not recognize the "excessiveness" of their fears. Situational and natural environment fears were the most frequent subtypes. Compared to respondents with no symptoms of anxiety, older adults with a full- or subthreshold-specific phobia reported more chronic physical health problems, more comorbid depressive disorders and a higher use of benzodiazepines. However, older adults with specific phobia reported more comorbid anxiety disorders than respondents with subthreshold fears.

CONCLUSIONS

The present study provides evidence for the fact that subthreshold fears have a high prevalence among older adults. Since several older people with specific phobia do not recognize the "excessiveness" of their fears, it is recommended that DSM-V criteria allow clinicians to rely on their own judgment to assess whether the perceived danger is out of proportion.

The impact of DSM-IV symptom and clinical significance criteria on the prevalence estimates of subthreshold and threshold anxiety in the older adult population

OBJECTIVES

Subthreshold anxiety refers to a condition where individuals do not meet the full symptom criteria (i.e., the number of symptoms required for a formal diagnosis is not reached) and/or do not report significant impairment or distress in functioning (i.e., the clinical significance criterion is not met). The purpose of this study was to examine how the symptom and the clinical significance criteria may affect the prevalence estimates of anxiety problems in the older adult population and whether applying these criteria results in an identifiable older group showing more severe anxiety.

SETTING AND PARTICIPANTS

Data came from a large representative sample of community-dwelling older adults age 65 years and older (N = 2,784).

RESULTS

Results showed that the 12-month prevalence rate of any anxiety problem varied from 5.6% when DSM-IV criteria for anxiety disorders were used to 26.2% when all subthreshold manifestations of anxiety were considered. Findings also indicated that when compared with respondents without anxiety, older adults presenting different manifestations of subthreshold or threshold anxiety appear to be more similar than different in their health and health behavior characteristics.

CONCLUSIONS

Subthreshold anxiety has a high prevalence and may cause significant impairment. Both symptom and clinical significance criteria do not perfectly discriminate between older adults with or without a severe anxiety problem presenting comorbid disorders and needing psychiatric help.

Coping with preclinical disability: older women's experiences of everyday activities

PURPOSE

The purpose of this paper is to describe coping practices used by older women during preclinical disability.

DESIGN

This paper was derived from qualitative data gathered during a larger multimethod longitudinal study. Twelve women (60 to 80 years of age) participated in baseline functional performance measures and then repeated in-depth interviews and participant observations over 18 months.

METHODS

A hermeneutic approach was used to interpret the in-depth interviews, participant observations, and field notes using three interrelated processes of thematic, exemplar, and identification of paradigm cases to identify coping practices.

FINDINGS

Women coped with functional decline, such as difficulty getting up from the floor, in many different ways. Coping practices were grouped into five themes: resist, adapt, substitute, endure, and eliminate.

CLINICAL RELEVANCE

These findings suggest that nurses need to realize outward appearances may mask the level of effort required for older women to complete daily activities.

Timing of impairment and health-promoting lifestyles in women with disabilities

The purpose of this study was to develop a substantive theory to explain how the timing of impairment in women's lives influenced health-promoting lifestyles among 45 women age 43 to 79 years with impairments of varying onset across the life course. From this grounded theory exploration, we suggest that women created health-related lifestyles that were comprised of changing abilities, roles, and rituals in support of perceived self. The ultimate goal of a healthy lifestyle was healthy aging, which was self-determination in the support of positive relationships. Environment and resources had direct influence on the perceived self. Our proposed substantive theory provides an understanding of how women develop a healthy lifestyle after the onset of permanent sensory or physical impairment. It also takes steps toward an understanding of how timing of impairment influences the perceptions women have of themselves and their health behaviors.

Timing, social support, and the effects of physical limitations on psychological distress in late life

OBJECTIVES

Previous research shows that limitations in activities of daily living (ADLs) are related to greater psychological distress. This study uses a synthesis of life course and stress process perspectives to examine how social support resources and the timing of limitations intersect to shape the relationship between ADL limitations and changes in psychological distress.

METHODS

Data are derived from a longitudinal study of adults aged 65 and older in the Washington, DC, metropolitan area over a 2-year period (2001-2003).

RESULTS

ADL limitations are positively related to change in depressive symptoms. This relationship is weakened for older individuals, but only at higher levels of perceived social support.

DISCUSSION

The contribution of this research is to offer a more nuanced view of the mental health consequences of physical limitations in late life by demonstrating that perceived social support provides an important context for age-variegated associations between ADL limitations and changes in psychological distress.

Social Networks in the NSHAP Study: rationale, measurement, and preliminary findings

OBJECTIVES

This paper describes the rationale behind the National Social Life, Health, and Aging Project's (NSHAP) social networks module, data collection procedures, and the measurement of several egocentric network properties. This includes a discussion of network size, composition, volume of contact with network members, density, and bridging potential. Data on the extent to which older adults involve network members in personal health matters are also discussed.

METHODS

Descriptive statistics are presented for key network measures. Sociodemographic distributions of these measures are presented. Older adults' likelihood of discussing health with network members is also broken down by network member characteristics.

RESULTS

Older adults tended to have large, kin-centered, dense networks, with some bridging potential. Network characteristics were related to age, gender, race/ethnicity, education, and health. Older adults tended to be very likely to involve network members (especially close ties) in health discussions and medical decision making.

DISCUSSION

The data reiterate the relevance of social networks to older adults' health. We close by discussing how the NSHAP measures might be employed in future analyses of health.

Network bridging potential in later life: life-course experiences and social network position

Objective. Much work in social gerontology has examined older adults' social connectedness, but we know little about the extent to which older adults occupy positions of power and independence in their networks. The author uses health and life-course frameworks to understand older adults' prospects of occupying bridging positions between otherwise unconnected individuals. Methods. Egocentric social network data were collected from a nationally representative sample of 3,005 older adults between the ages of 57 and 85 in 2005-2006. A series of multivariate regression analyses was used to examine how health and life-course factors relate to bridging. Results. Age is not significantly associated with bridging. However, retirees and people with poor health are less likely to have bridging potential. At the same time, widows are more likely to serve as bridges. Discussion. The discusses the need for more dialogue between social network researchers and social gerontologists to help explain older adults' bridging prospects.

The Social Connectedness of Older Adults: A National Profile*

For decades, scholars have wrestled with the notion that old age is characterized by social isolation. However, there has been no systematic, nationally representative evaluation of this possibility in terms of social network connectedness. In this paper, the authors develop a profile of older adults' social integration with respect to nine dimensions of connectedness to interpersonal networks and voluntary associations. The authors use new data from the National Social Life, Health, and Aging Project (NSHAP), a population-based study of non-institutionalized older Americans aged 57-85 conducted in 2005-2006. Findings suggest that among older adults, age is negatively related to network size, closeness to network members, and number of non-primary-group ties. On the other hand, age is positively related to frequency of socializing with neighbors, religious participation, and volunteering. In addition, it has a U-shaped relationship with volume of contact with network members. These findings are inconsistent with the notion that old age has a universal negative influence on social connectedness. Instead, life course factors have divergent consequences for different forms of social connectedness. Some later life transitions, like retirement and bereavement, may prompt greater connectedness. The authors close by urging increased dialogue between social gerontological and social network research.
