Multivariate analysis of independent determinants of ADL/IADL and quality of life in the elderly. BMC Geriatr 2022; 22:894. [PMID: 36418975 PMCID: PMC9682836 DOI: 10.1186/s12877-022-03621-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Accepted: 11/14/2022] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND This study evaluated the determinants of disability and quality of life in elderly people who participated at the multi-centred RubiN project (Regional ununterbrochen betreut im Netz) in Germany. METHODS Baseline data of the subjects aged 70 years and older of the RubiN project were used and only subjects with complete data sets were considered for the ensuing analysis (complete case analysis (CCA)). Disability was examined using the concepts of ADL (activities of daily living) and IADL (instrumental activities of daily living). Subjects exhibiting one or more deficiencies in ADL respectively IADL were considered as ADL respectively IADL disabled. Quality of life was assessed using the WHOQOL-BREF and the WHOQOL-OLD. Applying multivariate analysis, sociodemographic factors, psychosocial characteristics as well as the functional, nutritional and cognitive status were explored as potential determinants of disability and quality of life in the elderly. RESULTS One thousand three hundred seventy-five subjects from the RubiN project exhibited data completeness regarding baseline data. ADL and IADL disability were both associated with the respective other construct of disability, sex, a reduced cognitive and functional status as well as domains of the WHOQOL-BREF. Furthermore, ADL disability was related to social participation, while IADL disability was linked to age, education and social support. Sex, ADL and IADL disability, income, social support and social participation as well as the functional status were predictors of the domain 'Physical Health' (WHOQOL-BREF). The facet 'Social Participation' (WHOQOL-OLD) was affected by both ADL and IADL disability, income, social participation, the nutritional and also the functional status. CONCLUSIONS Several potential determinants of disability and quality of life were identified and confirmed in this study. Attention should be drawn to prevention schemes as many of these determinants appear to be at least partly modifiable.

International depiction of the cost of functional independence limitations among older adults living in the community: a systematic review and cost-of-impairment study. BMC Geriatr 2022; 22:815. [PMID: 36273139 PMCID: PMC9587635 DOI: 10.1186/s12877-022-03466-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Accepted: 09/07/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Functional independence limitations restrict older adult self-sufficiency and can reduce quality of life. This systematic review and cost of impairment study examined the costs of functional independence limitations among community dwelling older adults to society, the health care system, and the person. METHODS Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines this systematic review included community dwelling older adults aged 60 years and older with functional independence limitations. Databases (Cochrane Database of Systematic Reviews, EconLit, NHS EED, Embase, CINAHL, AgeLine, and MEDLINE) were searched between 1990 and June 2020. Two reviewers extracted information on study characteristics and cost outcomes including mean annual costs of functional independence limitations per person for each cost perspective (2020 US prices). Quality was assessed using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist. RESULTS 85 studies were included. The mean annual total costs per person (2020 US prices) were: $27,380.74 (95% CI: [$4075.53, $50,685.96]) for societal, $24,195.52 (95% CI: [$9679.77, $38,711.27]) for health care system, and $7455.49 (95% CI: [$2271.45, $12,639.53]) for personal. Individuals with cognitive markers of functional independence limitations accounts for the largest mean costs per person across all perspectives. Variations across studies included: cost perspective, measures quantifying functional independence limitations, cost items reported, and time horizon. CONCLUSIONS This study sheds light on the importance of targeting cognitive markers of functional independence limitations as they accounted for the greatest costs across all economic perspectives.

Abstract
The primary treatment goal of patients experiencing chronic pain has shifted from pain reduction to functional status improvement. However, the prevalence of disability and its associated factors in patients with chronic pain remain unknown.Individuals aged ≥50 years who visited the Pain Center at Nara Medical University with chronic pain from June 2019 to May 2020 were eligible for enrollment. Patients were asked to complete the Japanese version of the 12-item World Health Organization Disability Assessment Schedule 2.0. Patient demographics, pain intensity, level of catastrophizing, anxiety, depression, and exercise habits were assessed. Multivariate logistic regression analysis was used to identify the factors associated with disability.Of the 551 patients with a median age of 73 years, 51.5% experienced disability. Fixed factors such as age (odds ratio [OR], 1.03; 95% confidence interval [CI] 1.01-1.06, P = .002) and lumbar and lower limb pain (OR, 3.10; 95% CI, 1.83-5.24, P < .001) and some modifiable factors, including anxiety (OR, 2.06; 95% CI, 1.06-3.98, P = .03), depression (OR, 3.62; 95% CI, 1.92-6.82, P < .001), pain catastrophizer (OR, 2.94; 95% CI, 1.88-4.61, P < .001), numeric rating scale at the most painful site (OR, 1.29; 95% CI, 1.18-1.42, P < .001), exercise habits (walking (OR, 0.52; 95% CI, 0.33-0.83, P = .006) and working out (OR, 0.58; 95% CI, 0.34-0.99, P = .046), were found to be independently associated with disability.This cross-sectional study revealed a high prevalence of disability in patients with chronic pain and identified the factors associated with disability.

Associations between Disability in Activities of Daily Living and Social Capital aspects among older adults: a scoping review. J Frailty Sarcopenia Falls 2021; 6:119-130. [PMID: 34557611 PMCID: PMC8419853 DOI: 10.22540/jfsf-06-119] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/25/2021] [Indexed: 11/29/2022] Open
Abstract
Social capital aspects are playing an important role in activities of daily living (ADL) performance, thus on independent living. This paper was aimed to present an overview of the associations and adverse effects between social capital aspects and disability in ADL and health-related quality of life (HRQoL) in an older population aged 65 years old and over. Α scoping review was designed following the guidelines of PRISMA Extension for Scoping Reviews (PRISMA-ScR) and the review was conducted by 3 authors. A total of 185 primary studies were extracted and, finally, 40 studies did meet the inclusion criteria and critically appraised in two main categories; Category 1(29 studies) ‘social capital and disability in ADL’ deducing that as greater a social capital as better ADL performance and Category 2 (11 studies) ‘Social capital and HRQoL’ concluding that people 65 years old and over with lower social capital were presented with a poor HRQoL. Study synthesis highlights the impact of social capital suggesting that nurses caring for older people must focus on their engagement in terms of social diversity and trust in the community.

Disability trajectories prior to death for ten leading causes of death among middle-aged and older adults in Taiwan. BMC Geriatr 2021; 21:420. [PMID: 34246236 PMCID: PMC8272348 DOI: 10.1186/s12877-021-02300-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2020] [Accepted: 05/26/2021] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Prolonged life expectancy is associated with increased prevalence of chronic diseases. The aim of this study was to determine the different disability trajectories for the top ten leading causes of death in Taiwan . METHODS A total of 2,431 participants aged 50-96 in 1996 from the Taiwan longitudinal study on aging (TLSA) who died from 1996 to 2016 were analyzed. Integration of Cause of Death Data and TLSA helped sort out participants who had died from the ten leading causes of death. The level of physical disability was evaluated with the Activities of Daily Living Scale (ADLs), ranging from 0 to 6 points, in 1996, 1999, 2003, 2007, and 2011. A multilevel model was used to investigate the levels and rates of change in disability development before death. RESULTS The outcome of the research showed that the earliest group to experience physical limitation was individuals living with diabetes. The groups with the highest ADL scores were participants with diabetes, cerebrovascular disease, and hypertension-related diseases. Most groups reach ADL scores ≥ 1 (mild-level) during 4-6 years before death except chronic hepatitis and cirrhosis and injury. CONCLUSIONS People who had died from the ten leading causes of death experienced different disability trajectories before death. The trajectory of the participants who had died from diabetes showed a unique pattern with the earliest occurrence and more severe deterioration in terms of development of disabilities. Disability trajectories provide a prediction of survival status for middle-aged and older adults associated with the ten leading causes of death.

Abstract
OBJECTIVE We examined the neural substrates of social support in older adults. Social support is associated with better outcomes in many facets of aging-including cognitive and functional health-but the underlying neural substrates remain largely unexplored. METHODS Voxel-based morphometry and multivariate statistics were used to identify gray matter volume covariance networks associated with social support in 112 older adults without dementia (M age = 74.6 years, 50% female), using the Medical Outcomes Study Social Support Survey. RESULTS A gray matter network associated with overall social support was identified and included prefrontal, hippocampal, amygdala, cingulate, and thalamic regions. A gray matter network specifically associated with tangible social support (e.g., someone to help you if you were confined to bed) was also identified, included prefrontal, hippocampal, cingulate, insular, and thalamic regions, and correlated with memory and executive function. DISCUSSION Gray matter networks associated with overall and tangible social support in this study were composed of regions previously associated with memory, executive function, aging, and dementia. Longitudinal research of the interrelationships between social support, brain structure, and cognition is needed, but strengthening social support may represent a new path toward improving cognition in aging that should be explored.

Abstract
Disability is a tremendous public health challenge. No study has assessed whether meeting U.S. Physical Activity guidelines is associated with disability in mobility tasks, activities of daily living, and social participation among U.S. older adults. Using 2011-2016 National Health and Nutrition Examination Survey data, this study examined this relationship among 8,309 individuals aged ≥50 years. Most participants (n = 4,272) did not achieve guidelines, and 2,912 participants were completely inactive. People who did not meet guidelines had higher odds of disability compared with those who did (adjusted odds ratio [AOR] = 1.80) in addition to difficulty with mobility tasks (AOR = 1.85), activities of daily living (AOR = 1.66), and social participation (AOR = 2.09). There was a dose-response effect for each level of activity (inactive, insufficient, and meeting and exceeding recommendations). Among adults aged ≥50 years, meeting the U.S. guidelines was associated with better social and physical functioning.

Abstract
BACKGROUND Previous studies have shown that regular dental visits can affect the relationship of tooth loss with mortality and functional disability. However, the independent association between regular dental visits and incident functional disability is unclear. METHODS Our study participants were community-dwelling individuals aged ≥65 years, without disability at baseline. The outcome was the level of incident functional disability, as defined in a new certification of the public long-term care insurance. We defined no disability as no certification at follow-up, mild disability as support levels 1-2 and care level 1 (i.e., independent in basic ADL, but requiring some help in daily activities), and severe disability as care levels 2-5 (i.e., dependent in basic ADL). The exposure variable, based on the questionnaire, was regular dental visits at baseline. Covariates included gender, age, socio-economic status, health status, lifestyle habits, physical and mental functioning, and oral health variables. Using multinomial logistic regression, we calculated adjusted odds ratio (aOR) and 95 % confidence interval (CI) for mild disability and severe disability, with no disability as a reference category. RESULTS Among 8,877 participants, the 33-month cumulative incidence of mild and severe disability was 6.0 % and 1.8 %, respectively. After controlling for all covariates, regular dental visits at baseline were significantly associated with a lower risk of incident severe disability (aOR 0.65; 95 % CI, 0.46-0.91) but not the incidence of mild disability (aOR 0.96; 95 % CI, 0.79-1.17). CONCLUSIONS Encouraging dental visits may contribute to prevention of severe functional disability and extension of healthy life expectancy among community-dwelling older adults.

Abstract
BACKGROUND Among older adults, poorer cognitive functioning has been associated with impairments in instrumental activities of daily living (IADLs). However, IADL impairments among older Hispanics/Latinos is poorly understood. OBJECTIVE To characterize the relationships between cognition and risk for IADL impairment among diverse Hispanics/Latinos. METHODS Participants included 6,292 community-dwelling adults from the Study of Latinos - Investigation of Neurocognitive Aging, an ancillary study of 45+ year-olds in the Hispanic Community Health Study/Study of Latinos. Cognitive data (learning, memory, executive functioning, processing speed, and a Global cognitive composite) were collected at Visit 1. IADL functioning was self-reported 7 years later, and treated as a categorical (i.e., risk) and continuous (i.e., degree) measures of impairment. Survey two-part models (mixture of logit and generalized linear model with Gaussian distribution) and ordered logistic regression tested the associations of cognitive performance (individual tests and composite z-score) with IADL impairment. Additionally, we investigated the moderating role of age, sex, and Hispanic/Latino background on the association between cognition and IADL impairment. RESULTS Across all cognitive measures, poorer performance was associated with higher odds of IADL impairment 7 years later. Associations were generally stronger for the oldest group (70+ years) relative to the youngest group (50-59 years). Sex and Hispanic/Latino background did not modify the associations. Across the full sample, lower scores on learning, memory, and the Global cognitive composite were also associated with higher degree of IADL impairment. CONCLUSION Across diverse Hispanics/Latinos, cognitive health is an important predictor of everyday functioning 7 years later, especially in older adulthood.

Abstract
Critically short telomeres indicate cellular senescence. Leukocyte telomere length (LTL) is regarded as an aging predictor. Osteoporosis is an age-related disease. The purpose of our study is to examine the association between LTL, and BMD and osteoporosis among an elderly Chinese population. A total of 1017 participants (584 postmenopausal women) with a mean age of 66.4 years were recruited from April 2016 to August 2017. Dual-energy X-ray absorptiometry was used for BMD measurement at skeleton sites of lumbar spine (LS), femoral neck (FN), and total hip (TH). LTL was measured using quantitative real-time polymerase chain reaction. Among women, age significantly modified the effect of LTL on BMD at FN. Additionally, significant age modification was observed for the association between LTL and LS BMD category (indicative of control or osteopenia or osteoporosis), and the number of osteoporotic sites at LS or TH. The corresponding estimates (95% CI) for the relative excess risk due to interaction (RERI) were - 0.07 (- 0.11, - 0.01) and - 0.11 (- 0.16, - 0.03) sequentially in ordinal logistic regression models. The estimated RERIs (95% CI) were - 0.11 (- 0.25, - 0.02) and - 0.23 (- 0.39, - 0.10) in multinomial logistic regression models for LS/FN/TH BMD category, and - 0.20 (- 0.31, - 0.09) and - 0.34 (- 0.49, - 0.21) for FN BMD category. However, similar findings did not show in men. The effect of LTL on BMD and osteoporosis risk is modified by age in elderly women but not in men, suggesting that the predictive role of LTL in bone loss differs by sex.

Abstract
Background: Food insecurity refers to the physical, social, and economic inability to access and secure sufficient, safe and nutritious food. Food insecurity has been found to be associated with poor health status, obesity, and chronic disease. To date, a relationship between food insecurity and functional limitations has not been described in of older adults. Methods: We examined 9309 adults ≥60 years old from the 2005-2014 National Health and Nutrition Examination Surveys (NHANES). Food security was categorized as full, marginal, low, and very low. Functional limitations were assessed as having difficulty in physical, basic or instrumental activities of daily living. Results: Of adults ≥60 years old (mean age: 70.5 ± 0.08, 51% female), the prevalence of full, marginal, low, or very low food insecurity was 7572 (81%), 717 (7%), 667 (8%), and 353 (4%), respectively. The prevalence of any functional limitations was 5895 (66.3%). The adjusted odds (OR [95%CI]) of having any functional limitation in marginal, low, and very low food security levels compared to full food security are: 1.08 [1.02-1.13], 1.16 [1.10-1.22], 1.14 [1.07-1.21], respectively. The association between levels of food insecurity and functional limitation is modified by race/ethnicity. Conclusions: Functional limitation is significantly associated with increasing food insecurity in older adults.

Abstract
BACKGROUND Previous studies have reported on the higher risk of functional decline among older patients with cancer. However, few have focused on factors of functional decline in older persons with cancer and are mainly hospital-based and focus on consequences of cancer treatment. The aim of the study was to identify determinants of functional decline in older subjects with cancer in a population-based study. METHODS Using cancer registries, we identified older subjects (age ≥ 65 years) with cancer in three prospective cohort studies from Gironde, a French department. Functional status was measured using the Instrumental Activities of Daily Living (IADL) and the basic Activities of Daily Living (ADL) scales, and functional decline was measured between cancer pre- and post-diagnosis visits. Studied variables were demographic and socioeconomic (age at diagnosis, sex, living alone, education), cancer-related (stage at diagnosis, treatment received), smoking status, health-related (polypharmacy, depressive symptomatology), and geriatric-specific (cognitive impairment or dementia). Analyses were performed using logistic regression models. RESULTS Age (≥85 years), cognitive impairment or dementia, and advanced stage at diagnosis were associated with a higher risk of ADL limitations, whether considering death or not. Age (≥85 years), education and polypharmacy were associated with a higher risk of ADL and/or IADL limitations. CONCLUSIONS We identified factors that could impact on ADL and/or IADL limitations in older patients with cancer. The information on these determinants is useful in clinical settings to identify patients with cancer at high risk of functional decline.

Abstract
Objectives We aimed to assess the longitudinal associations of socioeconomic status and physical functioning using a large population-based survey data in China. Method We used four waves of the Chinese Longitudinal Healthy Longevity Survey (2002-2011). Physical functioning was assessed by activities of daily living (ADL) and instrumental activities of daily living (IADL) measures. Socioeconomic status was assessed using educational attainment, occupational status, household income, financial resources, and access to health services. Latent growth curve model combined with selection model was utilized. Results High education was not associated with the baseline level or the rate of change in ADL score but predicted better baseline IADL functioning. High income was related to better IADL functioning but had no effect on the rate of change in IADL. Inadequate financial resources and unavailability of health services were mainly associated with poorer ADL and IADL functioning at baseline. White-collar occupation was unrelated to the trajectory of physical functioning. Discussion This study provides no support either for the cumulative disadvantage or age-as-leveler theory. Improving financial status and accessibility of health care services, especially in lower social classes, may help to improve the overall level of physical functioning of the older adults.

Abstract
UNLABELLED ABSTRACTBackground:As more older persons opt to age in place, there is a growing trend to hire migrant workers as live-in caregivers to care for them. This raises the need to examine the quality of care they receive within this unique care setting. The objective of this pilot study was to establish the components of quality of care as provided by migrant live-in caregivers. METHODS We interviewed a convenience sample of older persons cared for by migrant live-in caregivers and their relatives. When relatives reported that older persons could not be interviewed due to advanced dementia, only relatives were interviewed. Overall, 72 older persons and 117 relatives were interviewed. We used the Quality of Care Questionnaire (QuCQ) developed for this study to examine the main components of quality of care in this population. RESULTS Factor analysis using older persons' data revealed two factors. In the first factor, "caretaking," items concerning provision of prompt care exhibited the highest loadings. Items measuring interpersonal aspects of the care dynamic had the highest loadings in the second factor, thus labeled "relationship." The factor analysis based on relatives' data yielded similarities and differences with the one based on older persons' data. Yet, there were significant correlations between relative and older persons' responses when using the older persons' factor structure. CONCLUSIONS According to older persons and relatives, quality of care depends on the extent to which older persons' care-related needs, as well as social ones, are addressed. Appropriate evaluation of quality of care in the live-in setting is important for its improvement.

Abstract
OBJECTIVE To investigate causal factors of functional impairment in old age in a longitudinal approach. DESIGN A population-based prospective cohort study. SETTING Elderly individuals were recruited via GP offices at six study centers in Germany. They were observed every 1.5 years over six waves. PARTICIPANTS Three thousand two hundred fifty-six people aged 75 years and older at baseline. MEASUREMENTS Functional impairment was quantified by the Lawton and Brody Instrumental Activities of Daily Living scale (IADL) and the Barthel-Index (BI). RESULTS Fixed effects regressions revealed that functional impairment (IADL; BI) increased significantly with ageing (β=-.2; β=-1.1), loss of a spouse (β= .5; β=-3.1), not living alone in private household (β=-1.2; β=-5.5), depression (solely significant for IADL: β= .6) and dementia (β=-2.3; β=-18.2). The comorbidity score did not affect functional impairment. CONCLUSION Our findings underline the relevance of changes in sociodemographic variables as well as the occurrence of depression or dementia for functional impairment. While several of these causal factors for functional decline in the oldest old are inevitable, some may not be, such as depression. Therefore, developing interventional strategies to prevent depression might be a fruitful approach in order to delay functional impairment in old age.

Abstract
OBJECTIVE The study examined the relationship between functional limitation due to chronic diseases and absenteeism among full-time workers. The studied chronic diseases include arthritis/rheumatism, cancer, diabetes, heart disease, hypertension, lung disease, and stroke. METHODS We analyzed data from the 2011 to 2013 National Health Interview Survey. Economic impact was determined by workdays lost and lost income. RESULTS Increase in absenteeism was observed for each studied condition. Employees with multiple conditions also saw increase absenteeism. Employers lose 28.2 million workdays annually ($4.95 billion in lost income) due to functional limitation caused by chronic diseases. CONCLUSIONS The results show a burden on society due to functional limitation caused by studied chronic diseases. Employers should look into implementing intervention/prevention programs, such as the Chronic Disease Self-Management Programs, to help reduce the cost associated with absenteeism.

Abstract
This study examined the effect of Medicare (Part D) implementation on health outcomes among U.S. older adults. Study participants were initially extracted from the 2004–2008 Health and Retirement Study (HRS). Data from respondents who further participated in the HRS 2005–2007 Prescription Drug Study were analyzed (N = 746). This was a retrospective pre-post design with a treatment and a control group. The difference-in-differences approach with panel ordered logistic regressions was used to examine the Part D effect on three patient health outcomes before and after the implementation, controlling for patient sociodemographic characteristics. People with continuous Part D enrollment from 2006–2008 were less likely to have a worse self-rated health than those who were not enrolled in Part D (odds ratio [OR] = 0.48; p < .05). A higher Charlson Comorbidity Index score was associated with a higher likelihood of having worse self-rated overall health, worse mental health, and worse activities of daily living impairment (ORs = 1.12, 1.17, and 1.36, respectively; all ps < .001). The Part D implementation appears to have a positive effect on older adults’ overall health outcomes. A decrease in out-of-pocket cost for health care may encourage older adults to utilize more needed medications, which in turn helped maintain better health.

Abstract
Background. There is an important need to characterize risk factors for disability in Thailand, in order to inform effective prevention and control strategies. This study investigated factors associated with risk of 6 types of disability in Thailand's ageing population in 2002, 2007, and 2011. Methods. Data came from the Cross-Sectional National Surveys of Older Persons in Thailand conducted by the National Statistical Office (NSO) in 2002, 2007, and 2011. Stratified two-stage sampling was employed. Interviews of 24,835, 30,427, and 34,173 elderly people aged 60 and above were conducted in the respective study years. Prevalence of disabilities was measured, and factors associated with disability risk were assessed with probability-weighted multiple logistic regression. Results. Disability prevalence decreased slightly over the study period. The characteristics with greatest positive impact on disability prevalence were not working over the past week (average impact: 61.2%), age (53.7% per decade), and suffering from one or more chronic illnesses (46.3%). Conclusions. The strong observed positive impact of not working on disability prevalence suggests that raising the mandatory retirement age might result in some reduction of disability risk. Also, the observed positive impact of living with others (versus alone) on disability risk was somewhat unexpected.

Abstract
In this study, the author examined the effects of psychosocial and health factors on the ADL disability trajectory of low-income frail elders living in the community. She analyzed three-year longitudinal data with a maximum of 15 repeated observations from a cohort of elderly participants in Michigan’s Medicaid Waiver Program ( N=3,161), using the hierarchical linear modeling approach. Baseline data of this cohort were taken in 1999; a reassessment was conducted about every three months. The analysis shows that major risk factors for a poor activity of daily living (ADL) disability trajectory include being Black, older, living with nonspouse others, and no confidence in functional improvement. Presence of arthritis, cancer, and cognitive limitation had significant and modest effects on ADL disability trajectories. The findings have implications to community-based intervention programs for frail elderly persons in the community.

Abstract
Objective: This study investigated variables associated with physical functioning limitations among elderly African American women, controlling for genetics and common family environment. Method: Activities of daily living limitations (ADL) and instrumental activities of daily living limitations (IADL) are examined in 180 pairs of African American elderly twins using a co-twin control design. The association of chronic disease, other physical problems, lifestyle, and demographic factors with both measures are investigated. Results: Arthritis, hypertension, and more than 1 chronic disease are associated with ADL limitations and arthritis; diabetes, heart attack, and more than 1 chronic disease are associated with IADL limitations in univariate analyses. In multivariate analyses, a different set of additional variables is associated with the two measures. Discussion: Among elderly African American women, physical functioning limitations are influenced by the presence of chronic diseases, other physical problems, lifestyle, and demographics. These associations are not due to genetics or common family environment effects.

Abstract
Objectives: National surveys of older Americans routinely have included functional limitation items using either a leading approach (“how much difficulty do you have...”) or a neutral approach (“do you have any difficulty...”). This article evaluates the performance of scales based on these two approaches. Methods: Using responses from 595 randomly selected participants to the 1994 Health and Retirement Study, the authors compared prevalences and evaluated scales based on each approach with respect to the extent of missing data, face validity, reliability, predictive validity, convergent validity, and robustness of odds ratios in predictive models. Results: The authors found that leading questions provided higher estimates of functional limitations than neutral questions, but both approaches yielded scales with similar validity and reliability. However, for both approaches, scales incorporating degree of difficulty had better validity and reliability than those based on counts of tasks. All four approaches yielded substantially similar coefficients in a model predicting disability onset. Discussion: The authors conclude that, because they minimize survey time without compromising validity and reliability, items that explicitly capture degree of difficulty by asking “How much difficulty do you have...” may be the optimal approach for survey designers.

Abstract
Our purpose was to determine the extent to which a predetermined set of modifiable impairments predicted progression of disability. Method: We conducted a 3-year follow-up of two community-based cohorts of older adults. The impairment areas included lower extremity, upper extremity, hearing, vision, and affect. Home management and social or productive activities were the domains of function investigated. Results: All five impairments were of at least borderline significance in predicting decline in both functional domains in both cohorts with the exception of hearing for home management activities. The five impairments together explained from 17% to 23% of the decline seen in the functional outcomes (partial R2s 0.17 to 0.23). Discussion: Five prevalent and potentially modifiable impairments explained much of the progressive disability experienced. Given the priority that older patients place on function as a health outcome, these impairments should be routinely assessed and modified.

Abstract
Locomotive syndrome is a condition of reduced mobility due to impairment of locomotive organs. Since upright bipedal walking involves minutely controlled movement patterns, impairment of any aspect of the locomotive organs has the potential to adversely affect it. In addition to trauma, chronic diseases of the locomotive organs, which progress with repeated bouts of acute exacerbations, are common causes of the locomotive syndrome. In Japan's super-aging society, many people are likely to experience locomotive syndrome in the later part of their lives. Exercise intervention is effective in improving motor function, but because the subjects are elderly people with significant degenerative diseases of the locomotor organs, caution should be taken in choosing the type and intensity of exercise. The present review discusses the definition, current burden, diagnosis and interventions pertaining to the locomotive syndrome. The concept and measures are spreading throughout Japan as one of the national health policy targets.

Abstract
OBJECTIVES estimation of functional loss incidence and identification of risk factors associated with new disability onset in people aged 75 and older without severe dependence in a rural primary care setting. PATIENTS AND METHOD Prospective cohort study of a representative sample of people aged 75 years or older without severe dependence (Barthel Index>20 and Lawton Index>1) at a primary care center, with a 12-month follow-up. The baseline geriatric assessment recorded activities of daily living (ADL), sociodemographic information, numbers of drugs prescribed, previous hospital admissions and falls, cognitive function, hearing and visual capacity, body mass index, blood pressure, and the Short Physical Performance Battery to evaluate lower limb function. ADL was re-assessed after 12 months, defining functional loss as a fall of ≥10 points on the Barthel Index and/or ≥2 instrumental activities of the Lawton Index. Bivariate and multivariate analyses using logistic regression models were conducted to identify factors independently associated with functional loss. RESULTS Mean age was 81.7 years, 58.7% of patients were men, and 23.4% presented functional loss at the 12-month follow-up. Variables identified as independent predictors of functional loss were hospital admissions (aOR 3.92; 95%CI: 1.35-11.39), cognitive impairment (aOR 2.60; 95%CI: 1.39-4.92) and lower limbs functional limitation (aOR 2.01; 95%CI: 1.02-3.97). CONCLUSIONS Our results support the use of performance batteries in primary care for identifying elderly persons at risk of functional decline; and they also highlight the relevance of appropriate management of hospital admissions and planned discharges in order to preserve patients' functional status.

Abstract
Knee osteoarthritis (KOA) changes the force applied on the lower extremities. The purpose of this study was to investigate the relationship between various severity of KOA and the forces applied to the lower limb during walking. Sixty eight limbs were divided into three groups of mild, moderate and severe KOA and a healthy normal group according to the Kellgren–Lawrence scale. The subjects walked with a self-selected speed to collect five successful trials. The components of ground reaction forces i.e., medio-lateral (ML), first peak of antero-posterior (AP1), second peak of antero-posterior (AP2), first peak of vertical (VP1), second peak of vertical (VP2) and vertical valley (V.V) were collected. AP1 and AP2 had decreasing pattern with increasing disease severity. Although ML Peak and VV have shown rising trend from normal people to severe KOA, ML difference was not significant in various groups ([Formula: see text]). In addition, the VP1 did not differ significantly among the subjects. In contrast, the VP2 decreased significantly in OA subjects ([Formula: see text]). It seems that AP1 and VP2 components are more sensitive to KOA, which may be used to represent severity of knee OA.

Abstract
Objective To examine time-dependent predictors of functional impairment in older adults in Europe longitudinally. Methods Data were derived from the Survey of Health Ageing, and Retirement in Europe (2004–2013). Functional impairment was assessed by using activities of daily living (ADL) and instrumental activities of daily living (IADL) indices. Fixed effects regressions were used to estimate the effects of sociodemographic factors (age, marital status, living situation, and income deciles (median split)), lifestyle factors (smoking status and alcohol consumption per week), depression, cognitive function and chronic diseases on the outcome variables. Results Longitudinal regressions revealed that functional impairment increased significantly with age, the occurrence of depression, cognitive impairment, the number of chronic conditions, and less than daily alcohol consumption in the total sample and in both sexes. Moreover, the onset of smoking and living without a spouse/partner in household increased functional impairment in the total sample. The effect of depression on functional impairment was significantly more pronounced in men. Conclusion Our findings highlight the relevance of changes in age, depression, cognitive function, smoking and chronic diseases for functional impairment. Since particularly depression and smoking may be avoidable, developing strategies to prevent depression or stop smoking might be useful approaches to postpone functional impairment in older adults.

Abstract
OBJECTIVES To identify the relationships between physical and/or cognitive frailty and instrumental activities of daily living (IADL) functioning in community living older persons. DESIGN Cross sectional observation study. SETTING Data extracted from the 2011-2013 of the National Center for Geriatrics and Gerontology-Study of Geriatric Syndromes (NCGG-SGS) database. PARTICIPANTS A total of 8,864 older adults aged ≥ 65 years who were enrolled in the NCGG-SGS. MEASUREMENTS We characterized physical frailty as limitations in three or more of the following five domains: slow walking speed, muscle weakness, exhaustion, low activity and weight loss. To screen for cognitive impairment, we used the National Center for Geriatrics and Gerontology-Functional Assessment Tool (NCGG-FAT) which included tests of word list memory, attention and executive function (tablet version of the Trail Making Test, part A and B), and processing speed (tablet version of the Digit Symbol Substitution Test). Two or more cognitive impairments indicated by an age-adjusted score of at least 1.5 standard deviations below the reference threshold was characterized as cognitive impairment. Each participant reported on their IADL status (use of public transportation, shopping, management of finances, and housekeeping) and several potential confounders such as demographic characteristics. RESULTS The overall prevalence of physical frailty, cognitive impairment, and cognitive frailty, i.e. co-occurrence of frailty and cognitive impairment, was 7.2%, 5.2%, and 1.2%, respectively. We found significant relationships between IADL limitations and physical frailty (Odds Ratio (OR) 1.24, 95% confidence interval (95% CI) 1.01 to 1.52), cognitive impairment (OR 1.71, 95% CI 1.39 to 2.11), and cognitive frailty (OR 2.63, 95% CI 1.74 to 3.97). CONCLUSION Using the NCGG-SGS frailty criteria, we found more participants with physical frailty than with cognitive frailty. The individuals with cognitive frailty had the highest risks of IADL limitations. Future investigation is necessary to determine whether this population is at increased risk for incidence of disability or mortality.

Abstract
BACKGROUND Discharge planning is a critical feature of hospital's care in geriatric rehabilitation centers. The aim of this study was to evaluate the effects of comorbidity and functionality in identifying patients who are at risk of discharge problems. We also evaluate the association between Blaylock Risk Assessment Screening Score, BRASS index (BI), and post-hospitalization outcome (PHO). METHODS Eighty patients (58 women and 22 men, with mean age equal to 83.28 ± 6.77 years) at geriatric rehabilitation division admission were screened with Geriatric Multidimensional Assessment (GMA). Then, BI and PHO were evaluated (mean follow-up time was 205.1 ± 95.8 days). By Structural Equation Model, we evaluated the existing causal relationships between comorbidity, functionality and PHO, elements of GMA, and the association between PHO and BI. RESULTS Comorbidity acted on PHO through functionality with indirect effect only (+0.703, P = 0.019). So, the functionality assumes a pivotal role of the causal relationship comorbidity to PHO. BI is positively associated with PHO: correlation returned was equal to +0.313 (P = 0.019). CONCLUSIONS The comorbidity has a role in getting worse PHO, but its effect is possible only through the mediation of functional status. The study also demonstrated the positive association between BI and PHO.

Abstract
This article tests whether functional status is associated with likelihood of social contact among older adults. Data come from the Second Longitudinal Study on Aging, a longitudinal nationally representative sample of 9,447 noninstitutionalized individuals aged 70 and over at baseline in 1995. Functional status is measured using an index of activities of daily living (ADL) and instrumental activities of daily living (IADL). Social contact is measured by asking respondents whether they had gotten together socially or talked on the phone with friends/neighbors or family in the past 2 weeks. Greater number of functional limitations is associated with a decreased likelihood of social contact at follow-up via the phone with friends (odd ratio [OR] = 0.94, p < .01) and family (OR = 0.96, p < .01), and a decreased likelihood of getting together with friends (OR = 0.93, p < .01) and family (OR = 0.97, p < .01). Results indicate that functional limitations have a broad impact on self-reported social contact among older adults.

Abstract
As the population ages, the numbers of people developing care- and cost-intensive forms of dementia are raising. We investigated the pathways of incident dementia patients to long-term care (LTC) dependence and death, and examined the effects of: (1) the type of the main treating physician, differentiated by neurologists/psychiatrists (NPs) and non-NPs; (2) the prescription of antidementive drugs on the risk of needing LTC, differentiated by the degree of care need. Longitudinal claims data of the largest German public sickness fund of 10,043 incident dementia cases aged 60 years and above were analyzed for the years 2006 to 2010. Cox proportional hazard models were performed to investigate the risk of LTC and death based on what type of physician was treating the patient, and whether the patient was prescribed antidementive drugs; adjusted for age, gender, cardiovascular comorbidities, and the previous LTC level. The patients who were primarily treated by NPs had a significantly lower risk of LTC than patients who were mainly treated by non-NPs (considerable LTC: RR = 0.72, p = 0.000, severe LTC: RR = 0.78, p = 0.000, extreme LTC: RR = 0.67, p = 0.001). They generally had a lower risk of death. Antidementive drug treatment was correlated with an increased risk of LTC (considerable LTC: RR = 1.66, p = 0.000, severe LTC: RR = 1.50, p = 0.000, extreme LTC: RR = 1.48, p = 0.000) but with a decreased risk of death. A higher rate of involvement of specialists in the treatment of dementia patients is associated with a reduced LTC dependence and increased survival of dementia patients. Antidementive drug treatments appear to extend live years with dementia.

Abstract
OBJECTIVES To determine whether weight loss in older adults may be a marker of impending burden of multimorbidity regardless of initial weight, testing the hypotheses that obesity but not overweight in elderly adults is associated with greater number of diseases than normal weight and that obese older adults who lose weight over time have the greatest burden of multimorbidity. DESIGN Longitudinal cohort study (Invecchiare in Chianti Study). SETTING Community. PARTICIPANTS Individuals aged 60 and older at baseline followed for an average of 4 years (N = 1,025). MEASUREMENTS Multimorbidity was measured as number of diagnosed diseases. Baseline body mass index (BMI) was categorized as normal weight (<25.0 kg/m(2)), overweight (25.0-29.9 kg/m(2)), and obese (≥30.0 kg/m(2)). Loss of weight was defined as decrease over time in BMI of at least 0.15 kg/m(2) per year. Age, sex, and education were covariates. RESULTS Baseline obesity was cross-sectionally associated with high multimorbidity and greater longitudinal increase of multimorbidity than normal weight (P = .005) and overweight (P < .001). Moreover, obese participants who lost weight over follow-up had a significantly greater increase in multimorbidity than other participants, including obese participants who maintained or gained weight over time (P = .005). In nonobese participants, changes in weight had no effect on changes in multimorbidity over time. Sensitivity analyses confirmed that one specific disease did not drive the association and that competing mortality did not bias the association. CONCLUSION Loss of weight in obese older persons is a strong biomarker of impending expansion of multimorbidity. Older obese individuals who lose weight should receive thoughtful medical attention.

Abstract
OBJECTIVES To describe the prevalence of joint stiffness and associated comorbidities in community-living older adults and to determine whether joint stiffness, independent of pain, contributes to new and worsening disability. DESIGN Population-based cohort. SETTING Urban and suburban communities in the Boston, Massachusetts, area. PARTICIPANTS Adults aged 70 and older (N = 765) underwent a baseline home interview and clinic examination, 680 participants completed the 18-month follow-up. MEASUREMENTS Morning joint stiffness on most days in the past month was assessed in the arms, back, hips, and knees. Mobility limitations were measured using self-reported difficulty and the Short Physical Performance Battery (SPPB). The home interview and clinic examination included extensive health measures. RESULTS Four hundred one participants reported morning joint stiffness, half of these with one site of stiffness and the other half with multisite stiffness. Twenty percent of participants with multisite stiffness and 50% with single site stiffness did not have a major stiffness-associated condition. After adjustment for pain severity and other covariates, multisite stiffness was associated with a 64% greater risk of developing new or worsening mobility difficulty (relative risk = 1.64, 95% confidence interval = 1.05-2.79). Those with multisite stiffness had declined more quickly in physical performance over the 18-month follow up. CONCLUSION Older adults with multisite stiffness are more likely to be at risk of disability than those without joint stiffness after accounting for pain severity and the presence of stiffness-associated conditions. Better assessment, along with strategies to prevent and treat multisite joint stiffness is needed to prevent or slow the progression of disability in elderly adults.

[PMID: 25523712 PMCID: PMC4301079 DOI: 10.1186/1471-2458-14-1301] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2014] [Accepted: 12/12/2014] [Indexed: 11/30/2022] Open
Abstract
Background Although many physical activity (PA) programs have been implemented and tested for effectiveness, high participation levels are needed in order to achieve public health impact. This study aimed to determine participation levels of PA programs aimed to improve PA among community-dwelling older adults. Methods We searched five databases up until March 2013 (PubMed, PubMed publisher, Cochrane Library, EMBASE, and Web of Science) to identify English-written studies investigating the effect of PA programs on at least one component of PA (e.g. frequency, duration) among community-dwelling populations (i.e. not in a primary care setting and/or assisted living or nursing home) of persons aged 55 years and older. Proportions of participants starting and completing the PA programs (initial and sustained participation, respectively) were determined. Results The search strategy yielded 11,994 records of which 16 studies were included reporting on 17 PA programs. The number of participants enrolled in the PA programs ranged between 24 and 582 persons. For 12 PA programs it was not possible to calculate initial participation because the number of older adults invited to participate was unknown due to convenience sampling. Of the five remaining programs, mean initial participation level was 9.2% (±5.7%). Mean sustained participation level of all 17 programs was 79.8% (±13.2%). Conclusions Understanding how to optimize initial participation of older adults in PA programs deserves more attention in order to improve the population impact of PA programs for community-dwelling older adults.

Income-related inequalities in chronic conditions, physical functioning and psychological distress among older people in Australia: cross-sectional findings from the 45 and up study. BMC Public Health 2014; 14:741. [PMID: 25048295 PMCID: PMC4223589 DOI: 10.1186/1471-2458-14-741] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2013] [Accepted: 07/09/2014] [Indexed: 11/17/2022] Open
Abstract
Background The burden of chronic disease continues to rise as populations age. There is relatively little published on the socioeconomic distribution of this burden in older people. This study quantifies absolute and relative income-related inequalities in prevalence of chronic diseases, severe physical functioning limitation and high psychological distress in mid-age and older people in Australia. Methods Cross-sectional study of 208,450 participants in the 45 and Up Study, a population-based cohort of men and women aged 45–106 years from New South Wales, Australia. Chronic conditions included self-reported heart disease, diabetes, Parkinson’s disease, cancer and osteoarthritis; physical functioning limitation (severe/not) was measured using Medical Outcomes Study measures and psychological distress (high/not) using the Kessler Psychological Distress Scale. For each outcome, prevalence was estimated in relation to annual household income (6 categories). Prevalence differences (PDs) and ratios (PRs) were generated, comparing the lowest income category (<$20,000) to the highest (≥$70,000), using Poisson regression with robust standard errors, weighted for age, sex and region of residence. Analyses were stratified by age group (45–64, 65–79 and ≥80 years) and sex and adjusted for age and country of birth. Results With few exceptions, there were income gradients in the prevalence of chronic conditions among all age-sex groups, with prevalence decreasing with increasing income. Of the chronic diseases, PDs were highest for diabetes (ranging between 5.69% and 10.36% across age-sex groups) and in women, also for osteoarthritis (5.72% to 8.14%); PRs were highest for osteoarthritis in men aged 45–64 years (4.01), otherwise they were highest for diabetes (1.78 to 3.43). Inequalities were very high for both physical functioning limitation and psychological distress, particularly among those aged 45–64 (PDs between 18.67% and 29.23% and PRs between 4.63 and 16.51). Absolute and relative inequalities tended to decrease with age, but remained relatively high for diabetes and physical functioning in the elderly (≥80 years). Conclusions Significant inequalities in the prevalence of chronic conditions, physical functioning and psychological distress persist into old age. The additional health burden placed on those who are already disadvantaged is likely to become an increasingly important issue in an ageing population.

Abstract
BACKGROUND Not only single, but also multiple, chronic conditions are becoming the normal situation rather than the exception in the older generation. While many studies show a correlation between multimorbidity and various health outcomes, the long-term effect on care dependency remains unclear. The objective of this study is to follow up a cohort of older adults for 5 years to estimate the impact of multimorbidity on long-term care dependency. METHODS This study is based on claims data from a German health insurance company. We included 115,203 people (mean age: 71.5 years, 41.4% females). To identify chronic diseases and multimorbidity, we used a defined list of 46 chronic conditions based on ICD-10 codes. Multimorbidity was defined as three or more chronic conditions from this list. The main outcome was "time until long-term care dependency". The follow-up started on January 1st, 2005 and lasted for 5 years until December 31st, 2009. To evaluate differences between those with multimorbidity and those without, we calculated Kaplan-Meier curves and then modeled four distinct Cox proportional hazard regressions including multimorbidity, age and sex, the single chronic conditions, and disease clusters. RESULTS Mean follow-up was 4.5 years. People with multimorbidity had a higher risk of becoming care dependent (HR: 1.85, CI 1.78-1.92). The conditions with the highest risks for long-term care dependency are Parkinson's disease (HR: 6.40 vs. 2.68) and dementia (HR: 5.70 vs. 2.27). Patients with the multimorbidity pattern "Neuropsychiatric disorders" have a 79% higher risk of care dependency. CONCLUSIONS The results should form the basis for future health policy decisions on the treatment of patients with multiple chronic diseases and also show the need to introduce new ways of providing long-term care to this population. A health policy focus on chronic care management as well as the development of guidelines for multimorbidity is crucial to secure health services delivery for the older population.

Weight loss over 48 months is associated with reduced progression of cartilage T2 relaxation time values: data from the osteoarthritis initiative. J Magn Reson Imaging 2014; 41:1272-1280. [PMID: 24700497 DOI: 10.1002/jmri.24630] [Citation(s) in RCA: 36] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2013] [Accepted: 02/20/2014] [Indexed: 02/06/2023] Open
Abstract
PURPOSE To assess whether changes in knee cartilage MR-based T2 relaxation times are associated with weight loss in individuals with risk factors for knee osteoarthritis (OA) compared with controls with stable weight. MATERIALS AND METHODS One hundred twenty-seven individuals with risk factors for knee OA were studied: 62 subjects had a body mass index (BMI) decrease≥10% over 48 months and 65 controls had a BMI change <3%. Cartilage segmentation from five knee compartments at baseline and 48-month follow-up was performed, and T2 maps were generated. The association of change in T2 values over 48 months in the weight-loss group versus the control group was assessed using multiple linear regression models. RESULTS Weight loss was associated with significantly smaller increases in cartilage T2 in the medial femoral condyle (P = 0.035) and overall medial compartment (P = 0.006) compared with the controls. In a subgroup analysis comparing weight-loss subjects who were obese (BMI≥30 kg/m(2) ) and overweight (BMI 25-30 kg/m(2) ) at baseline, obesity was associated with smaller increases in cartilage T2 values in the medial femoral condyle (P = 0.022), lateral femoral condyle (P = 0.015), patella (P = 0.002), and globally across all compartments (P = 0.002). CONCLUSION A decrease in BMI of ≥ 10% was associated with a slower progression of T2 values in individuals with risk factors for OA, suggesting a beneficial impact of weight loss on cartilage matrix degeneration.

Effects of impairment in activities of daily living on predicting mortality following hip fracture surgery in studies using administrative healthcare databases. BMC Geriatr 2014; 14:9. [PMID: 24472282 PMCID: PMC3922692 DOI: 10.1186/1471-2318-14-9] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2013] [Accepted: 01/13/2014] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Impairment in activities of daily living (ADL) is an important predictor of outcomes although many administrative databases lack information on ADL function. We evaluated the impact of ADL function on predicting postoperative mortality among older adults with hip fractures in Ontario, Canada. METHODS Sociodemographic and medical correlates of ADL impairment were first identified in a population of older adults with hip fractures who had ADL information available prior to hip fracture. A logistic regression model was developed to predict 360-day postoperative mortality and the predictive ability of this model were compared when ADL impairment was included or omitted from the model. RESULTS The study sample (N = 1,329) had a mean age of 85.2 years, were 72.8% female and the majority resided in long-term care (78.5%). Overall, 36.4% of individuals died within 360 days of surgery. After controlling for age, sex, medical comorbidity and medical conditions correlated with ADL impairment, addition of ADL measures improved the logistic regression model for predicting 360 day mortality (AIC = 1706.9 vs. 1695.0; c -statistic = 0.65 vs 0.67; difference in - 2 log likelihood ratios: χ(2) = 16.9, p = 0.002). CONCLUSIONS Direct measures of ADL impairment provides additional prognostic information on mortality for older adults with hip fractures even after controlling for medical comorbidity. Observational studies using administrative databases without measures of ADLs may be potentially prone to confounding and bias and case-mix adjustment for hip fracture outcomes should include ADL measures where these are available.

Abstract
Objectives: This is the first analysis that demonstrates empirically the likely tie between activities (time spent) and disability (health-related difficulty in activities). We compare trends in activities and disability for Americans ages 55 to 69 in recent years, and assess cross-sectional linkages of activities and disability. Methods: Data are from the Health and Retirement Study, a longitudinal survey of community-dwelling U.S. adults. Trends are estimated by mixed-effects regression models (MRMs) with time, age, and time–age interaction predictors. Links of activities and disability also use MRM. Results: For midlife adults, hobbies/leisure and sports/exercise increased, repairs/yard decreased, and several activities had convex patterns; by contrast, disability prevalence was stable. Personal care hours rise with disability, but most activities decline. Discussion: Activities are more dynamic than disability, and time use is associated with disability. Taken together, the results encourage broader activities in disability measures to capture better disability’s scope and dynamics.

Abstract
OBJECTIVES Although self-rated health (SRH) is recognized as a strong and consistent predictor of mortality and functional health decline, there are relatively few studies examining SRH as a predictor of morbidity. This study examines the capacity of SRH to predict the onset of chronic disease among the late midlife population (ages 51-61 years). METHOD Utilizing the first 9 waves (1992-2008) of the Health and Retirement Study, event history analysis was used to estimate the effect of SRH on incidence of 6 major chronic diseases (coronary heart disease, diabetes, stroke, lung disease, arthritis, and cancer) among those who reported none of these conditions at baseline (N = 4,770). RESULTS SRH was a significant predictor of onset of any chronic condition and all specific chronic conditions excluding cancer. The effect was particularly pronounced for stroke. DISCUSSION This research provides the strongest and most comprehensive evidence to date of the relationship between SRH and incident morbidity.
