Background It is not clear whether recent increases in life expectancy are accompanied by a concurrent postponement of activity limitations. The objective of this study was to give best estimates of the trend in the prevalence of activity limitations among the non-institutionalized population aged 55–84 years over the period 1990–2007 in The Netherlands.Methods We examined self-reports on 12 measures of moderate or severe activity limitations in stair climbing, walking and getting dressed as assessed by OECD long-term disability questionnaire or Short Form-36 (SF-36) items, using original data from five population-based cross-sectional and longitudinal surveys (n = 54 847 respondents). To account for heterogeneity between surveys, we used meta-analyses to study time trends.Results Time trends of 10 out of the 12 activity limitation variables studied were stable. The prevalence of at least moderate activity limitations in stair climbing [odds ratio (OR) = 1.03)] and getting dressed (OR = 1.04) based on OECD items increased over the study period. Age- and gender-stratified time trend analyses showed consistent patterns.Conclusions No declines were observed in the prevalence of activity limitations in the Dutch older population over the period 1990–2007. The increase in life expectancy in this period is accompanied by a stable prevalence of most activity limitations. [ABSTRACT FROM AUTHOR]

Objective: This article addresses the association between course of chronic disease and lifestyle. Method: We examined differences in unhealthy lifestyles--smoking, excessive alcohol use, being sedentary--and transitions herein after 6 years in prevalent and incident chronic disease categories--lung and cardiovascular disease, diabetes, and osteoarthritis and/or rheumatic arthritis--among 2,184 respondents aged 55 years and older from the Netherlands. We also examined if transitions in lifestyle co-occurred with changes in disease-related symptomatology. Results: Proportions of respondents who smoked decreased over time, whereas proportions of respondents who were sedentary increased. Respondents with incident cardiovascular disease demonstrated more lifestyle transitions than respondents from other disease categories. Respondents demonstrating healthy lifestyle transitions did not differ from those persisting in unhealthy lifestyles in change in disease-related symptoms. Discussion: Health promotion may benefit from these findings in a way that patient groups at risk for not initiating healthy lifestyles might be identified sooner. [ABSTRACT FROM AUTHOR]

Objectives. We examined whether healthy lifestyles are associated with absence of depressed mood. Methods. A sample of 1169 adult participants in the Maastricht Aging Study provided baseline and 6-year follow-up data on smoking, alcohol use, physical exercise, body mass index, and mood. We examined associations between lifestyles and depressed mood using longitudinal analyses controlling for baseline depressive symptoms and covariates. Results. Reports of excessive alcohol use at baseline predicted depressed mood at follow-up (relative risk [RR]=2.48; 95% confidence interval [CI]=1.08, 5.69), and reports of more than 30 minutes of physical exercise per day at baseline were associated with an absence of depressed mood at follow-up (RR=0.52; 95% CI=0.29, 0.92). Reports of being engaged in physical exercise throughout the 6-year follow-up period were also associated with absence of depressed mood (RR=0.56; 95% CI=0.34, 0.93). Conclusions. In this relatively healthy population sample, certain lifestyles either predicted or protected against depressed mood. Adopting or maintaining healthy lifestyles might be a starting point in preventing or treating depressed mood over time. [ABSTRACT FROM AUTHOR]

Abstract: Background: Determinants of adherence to lifestyle regimens are ill understood. Attendance to intervention sessions is crucial for patients to acquire knowledge and skills regarding the core elements of an intervention. Therefore, we explored demographic, health-related, and social determinants of high and low attendance to diet and exercise sessions among overweight and obese patients with knee osteoarthritis (≥60 years; N =206). Methods: The Arthritis, Diet, and Activity Promotion Trial was an 18-month randomized controlled trial on the effectiveness of dietary weight loss and exercise interventions. We conducted chi-square and t-tests, and logistic regression analyses on categories of short- and long-term attendance to intervention sessions. Results: Over the 18-month duration of the study, 60.7% (±28.5) of diet sessions, and 53.2% (±29.0) of exercise sessions were attended. Not being married, low social participation, and single intervention randomization predicted high attendance to diet sessions during months 1–4. Exercising at home, and single intervention randomization predicted high attendance to exercise sessions during months 5–18. High attendance to sessions early in the intervention was a significant determinant of high session attendance thereafter. Conclusions: Offering people a choice where to exercise, and stimulating early intervention session attendance can be effective in improving long-term attendance to both interventions. Several determinants we found may be amenable to change to enhance intervention adherence of future randomized controlled trials involving dietary weight loss and/or physical exercise.

The main pathway of the disablement process consists of four consecutive phases: Pathology (presence of disease/injury), Impairments (dysfunctions/structural abnormalities), Functional Limitations (restrictions in basic physical/mental actions), and Disability (difficulty doing activities of daily life, ADL). This study determines the presence of the main pathway of disablement in a cohort aged 55 years and older and examines whether progression of the main pathway of disablement is accelerated in the presence of depression. Based on baseline (T1) and two three-year follow-up interviews (T2 and T3) from the Longitudinal Aging Study Amsterdam (LASA) in a population-based cohort of 1110 Dutch persons, we first analysed the intermediate effect of the different consecutive phases of the disablement process by means of multiple regression, adjusted for covariates. Then, depression was used as interaction term in multiple regression analyses linking the consecutive phases of the disablement process. We found that Impairments mediated the association between Pathology and Functional Limitations, and that Functional Limitations mediated the association between Impairments and Disability. Depression significantly modified the associations between Pathology and subsequent Impairments, and between Functional Limitations and subsequent Disability. In sum, the main pathway of the disablement process was identified in our sample. In addition, we found an accelerating effect of depression, particularly in the early and late stages of the model. Reduction of depression may help slow down the process of disablement for persons who find themselves in those stages of the model. [Copyright &y& Elsevier]

Purpose:The ICF (International Classification of Functioning, Disability and Health) framework (used worldwide to describe ‘functioning’ and ‘disability’), including the ICF scheme (visualization of functioning as result of interaction with health condition and contextual factors), needs reconsideration. The purpose of this article is to discuss alternative ICF schemes. Method:Reconsideration of ICF via literature review and discussions with 23 Dutch ICF experts. Twenty-six experts were invited to rank the three resulting alternative schemes. Results:The literature review provided five themes: 1) societal developments; 2) health and research influences; 3) conceptualization of health; 4) models/frameworks of health and disability; and 5) ICF-criticism (e.g. position of ‘health condition’ at the top and role of ‘contextual factors’). Experts concluded that the ICF scheme gives the impression that the medical perspective is dominant instead of the biopsychosocial perspective. Three alternative ICF schemes were ranked by 16 (62%) experts, resulting in one preferred scheme. Conclusions:There is a need for a new ICF scheme, better reflecting the ICF framework, for further (inter)national consideration. These Dutch schemes should be reviewed on a global scale, to develop a scheme that is more consistent with current and foreseen developments and changing ideas on health.Implications for RehabilitationWe propose policy makers on community, regional and (inter)national level to consider the use of the alternative schemes of the International Classification of Functioning, Disability and Health within their plans to promote functioning and health of their citizens and researchers and teachers to incorporate the alternative schemes into their research and education to emphasize the biopsychosocial paradigm.We propose to set up an international Delphi procedure involving citizens (including patients), experts in healthcare, occupational care, research, education and policy, and planning to get consensus on an alternative scheme of the International Classification of Functioning, Disability and Health.We recommend to discuss the alternatives for the present scheme of the International Classification of Functioning, Disability and Health in the present update and revision process within the World Health Organization as a part of the discussion on the future of the International Classification of Functioning, Disability and Health framework (including ontology, title and relation with the International Classification of Diseases).We recommend to revise the definition of personal factors and to draft a list of personal factors that can be used in policy making, clinical practice, research, and education and to put effort in the revision of the present list of environmental factors to make it more useful in, e.g., occupational health care.

Background: Disability Adjusted Life Years (DALYs) quantify the loss of healthy years of life due to dying prematurely and due to living with diseases and injuries. Current methods of attributing DALYs to underlying risk factors fall short on two main points. First, risk factor attribution methods often unjustly apply incidence-based population attributable fractions (PAFs) to prevalence-based data. Second, it mixes two conceptually distinct approaches targeting different goals, namely an attribution method aiming to attribute uniquely to a single cause, and an elimination method aiming to describe a counterfactual situation without exposure. In this paper we describe dynamic modeling as an alternative, completely counterfactual approach and compare this to the approach used in the Global Burden of Disease 2010 study (GBD2010).Methods: Using data on smoking in the Netherlands in 2011, we demonstrate how an alternative method of risk factor attribution using a pure counterfactual approach results in different estimates for DALYs. This alternative method is carried out using the dynamic multistate disease table model DYNAMO-HIA. We investigate the differences between our alternative method and the method used by the GBD2010 by doing additional analyses using data from a synthetic population in steady state.Results: We observed important differences between the outcomes of the two methods: in an artificial situation where dynamics play a limited role, DALYs are a third lower as compared to those calculated with the GBD2010 method (398,000 versus 607,000 DALYs). The most important factor is newly occurring morbidity in life years gained that is ignored in the GBD2010 approach. Age-dependent relative risks and exposures lead to additional differences between methods as they distort the results of prevalence-based DALY calculations, but the direction and magnitude of the distortions depend on the particular situation.Conclusions: We argue that the GBD2010 approach is a hybrid of an attributional and counterfactual approach, making the end result hard to understand, while dynamic modelling uses a purely counterfactual approach and thus yields better interpretable results.
