“…A powerful association between ADL disability and mortality is recognized (Keeler et al, 2010). Thus our results support other studies demonstrating a hierarchical pattern of functional decline starting with limitations in mobility progressing on to disability in ADL and subsequent mortality (Guralnik et al, 2000;Wang, Sheu, & Protas, 2007). It is further recognized that walking requires energy and puts demand on multiple organ systems .…”

“…This composite measure, which captures a broad range of disability from early or "preclinical" disability to later personal care disability, has the advantage of capturing finer graduations in limitations and reducing ceiling or flooring effects. 17 Cronbach's alpha of the 16 items across all waves averaged 0.90.…”

BACKGROUND: Few longitudinal studies have examined associations between body mass index (BMI) changes in adults with diabetes and the development of disability. OBJECTIVE: To investigate association patterns between BMI and disability in middle-aged adults with diabetes. DESIGN AND SETTING: Retrospective cohort design with data from the 1992-2006 Health and Retirement Study (HRS). A group-based joint trajectory method identified distinct BMI change trajectories and their link to subsequent disability trajectories. PARTICIPANTS: U.S. nationally representative adults aged 51-61 who reported a diagnosis of diabetes in the 1992 HRS (N=1,064). MEASUREMENTS: BMI and self-reported disability score were the main variables. Sociodemographic, clinical, behavioral, and diabetes-related factors were also examined. RESULTS: Four distinct weight trajectories (stable normal weight, 28.7 %; stable overweight, 46.2 %; loss and regain obese, 18.0 %; weight cumulating morbidly obese, 7.1 %) and three disability trajectories (little or low increase, 34.4 %; moderate increase, 45.4 %; chronic high increase, 20.2 %) best characterized the long-term patterns of BMI and disability change in middle-aged adults with diabetes. Adults in stable normal weight had the highest probability of being in the little/low increase disability group; however, one in five adults in that group progressed into chronic high disability, a higher proportion compared to the stable overweight group. CONCLUSIONS: Although there were various ways in which the two trajectories were linked, the beneficial impacts of optimizing weight in adults with diabetes were supported. In addition, the complexity of diabetes control in those with relatively normal weight was highlighted from this study.

“…26,27 Test-retest reliability is high for both scales, ranging from 87% to 100%. 28 Using disability data from both scales, we created a dichotomized outcome of respondents with a disability 28 years later (people who encountered some degree of difficulty performing at least one of the basic or instrumental activities of daily living) versus respondents without a disability 28 years later.…”

P rospective studies with a follow-up time stretching from midlife to old age have shown that lower socioeconomic status, as indicated by lower education level or occupational grade, predicts a decline in health and functioning in the working population.1-4 This association is similar, if not more pronounced, in old age. 5-7Higher levels of work-related mental and physical strain increase the risk of early retirement and predict a decline in health and an increase in mortality among the working population. 3,[8][9][10][11][12][13][14][15] However, the association between the demands of the work in conjunction with inadequate mental or physical resources (i.e., work ability) 16 and health and functioning in old age has not been studied.17 Using a population-based 28-year follow-up study involving middle-aged municipal employees, we investigated whether work ability in midlife predicts the risk of death and disability during old age among white-collar and blue-collar employees. Methods Participants and designThe Finnish Institute of Occupational Health's Finnish Longitudinal Study on Municipal Employees (FLAME) targeted 7344 individuals aged 44-58 years at baseline in 1981.18 The participants had been chosen at random from members of all municipal professions in Finland. The baseline cohort consisted of 6257 employees (44.7% men), for a response rate of 85.2%. The first questionnaire, which explored work, health and lifestyle factors, was sent out in 1981, and follow-up data were collected in 1985, 1992, 1997 and 2009. Data on work ability were missing for 199 women and 87 men. The analyses in this study are based on the responses of 5971 Work ability in midlife as a predictor of mortality and disability in later life: a 28-year prospective follow-up study Mikaela B. von Research CMAJ Background: Poor work ability correlates with increased morbidity and early retirement from the workforce, but the association in old age is not known. We investigated work ability in midlife among white-collar and blue-collar employees as a predictor of mortality and disability 28 years later.
