RESUMEN
BACKGROUND: Although physical activity (PA) has been shown to be beneficial in older adults with osteoarthritis (OA), most show low levels of PA. This study evaluated if self-efficacy, attitude, social norm, and coping styles predicted change in PA in older adults with OA in the knee and/or hip. METHODS: Prospective study following 105 participants in a self-management intervention with baseline, post-test (6 weeks), and follow-up (6 months). Univariate associations and multivariate regression with self-reported change in PA as the dependent variable were measured. Potential predictors in the model: demographic, illness-related, and behavioral variables (attitude, self-efficacy, social norm, and intention), coping style, and pain coping. RESULTS: Forty-eight percent of participants reported increased PA at 6 weeks and 37% at 6 months which corresponded with registered PA levels. At 6 weeks, use of the pain coping style "resting," intention, and participation in the intervention was univariately and multivariately, positively associated with more self-reported change, whereas being single and less use of the pain coping style "distraction" predicted less change. Higher pain severity only predicted less change multivariately. At 6 months, univariate associations for age, general coping style "seeking support," and participation in the intervention were found; higher age was associated multivariately with less self-reported change. CONCLUSION: At short term, self-reported change of PA was predicted by the behavioral factors intention and several pain coping styles. Together with other predictors of self-reported change (pain severity, higher age, being single), these could be addressed in future interventions for enhancing PA in older adults with OA.

Within the context of a globally aging population and associated age-related changes to social relationships and individual psycho-physiology, a coalition of mostly European Union (EU) organizations concerned with physical activity in older persons was formed in 2013. The coalition examined worldwide decreases in physical activity among older adults, and the resulting negative effects on health and function for those individuals. After holding expert panel meetings, the coalition developed recommendations about how to address macro- and microlevel changes to increase and sustain physical activity among older populations across Europe. The recommendations were then compiled into a consensus document called "the Rome Statement", aimed at older adults, policy makers, researchers, and private and public professionals. This article presents the Rome Statement and its recommendations, and discusses how the statement can be broadly disseminated, considered, and implemented.

BACKGROUND: Physical activity (PA) levels of older adults living in a care setting are known to be very low. This is a significant health(care) problem, as regular PA has many health benefits also at advanced age. Research on automatic processes underlying PA behaviour in physically inactive older adults is yet non-existing. Since people are unconsciously influenced by people around them (i.e. by 'social norms') automatic processes could be used to promote PA. We developed an explorative intervention method to assess the effects of automatically processed (implicit) descriptive social norms ('What most people do') on behavioral intention and participation in PA offered in a local residential care setting. METHODS: Forty-seven care clients met the inclusion criteria. Participants (response 45%; unaware of the intention of the research) were randomly assigned to an experimental (N = 10) or a control group (N = 11). The experimental group was exposed to photos and text heading on active peers (physically active implicit descriptive norm) using a draft newsletter article they were asked to comment on, whereas the control group was exposed to a newsletter with photos and text heading of inactive peers (physically inactive implicit descriptive norm). Subsequently, we tested (Fishers exact p < 0.10) whether this unaware exposure predicted intention (implicit and explicit) to participate in PA offered and organized by the care center (e.g. walking, gymnastics) and self-reported participation in organised PA at three months follow-up. Participants were debriefed later. RESULTS: Mean age was 87 years (SD = 3.6; range 80-95) and 53% of the participants were male. At baseline, there were no significant differences in self-rated health and PA between the experimental and control group. Results indicated that implicit descriptive norm information was associated with implicit PA intention (p = .056, Fisher's exact test). No significant effects were found on explicit intention. At 3 months follow-up the experimental group self-reported 80% participation in PA versus 22% in the control group (Fisher's exact test p = 0.027). CONCLUSION: Implicit descriptive social norm information could indeed be a potentially effective way to encourage inactive older adults in residential care to engage in organized PA.

BACKGROUND: Chronic diseases and multimorbidity are increasingly common among persons in working age. This study explores the impact of type, number and combinations of chronic diseases with focus on the role of MSKD on (1) adverse work status (i.e. work disability (WD), economic unemployment (UE) or receiving a living allowance (LA)) and on (2) the occurrence of sick leave. METHODS: Subjects participating in a Dutch household survey, who were ≤65 years and could have paid work, provided data on socio-demographics and nine physician diagnosed chronic diseases. To explore the independent association of each chronic disease, of multimorbidity and of MSKD in context of multimorbidity with 1) work status (employed, WD, LA, UE) and 2) sick leave (SL) in those employed, multinomial logistic regressions and logistic regressions were used, respectively. RESULTS: Among 5396 subjects, MSKD was the most common morbidity (17%), multimorbidity occurred in 755/5396 (14%), 436/755 (61%) of subjects with multimorbidity had an MSKD. For MSKD the odds of WD, LA and UE were 2.06 [95% CI 1.56;2.71], 2.15[1.18;3.91] and 1.35[0.94;1.96], respectively, compared to being employed and the odds of SL in MSKD were 2.29[1.92;2.73]. Mental diseases had a stronger impact on all these outcomes. The odds for adverse work outcomes increased strongly with an increasing number of diseases. When an MSKD was part of multimorbidity, an additional impact on the association with WD and SL was observed. CONCLUSIONS: Multimorbidity has a stronger impact on all work outcomes compared to single chronic diseases. The presence of the MSKD in the context of multimorbidity amplifies the chance of WD or SL.

The predictive value of the Theory of Planned Behavior (TPB) on intention and physical activity (PA) over time was examined. Data from the Aging Well and Healthily intervention program (targeting perceived behavioral control and attitude, not subjective norm) were analyzed, including pretest (T0), posttest (T1, except subjective norm) and 4-6 months follow-up (T2, PA outcomes only) (N = 387, M age 72 years). Structural equation modeling was used to test a TPB model. PA was measured subjectively using the Voorrips sports subscale (T0 and T2), items measured perceived increase in PA (T1), and adherence to exercises (T1 and T2). Model fit was good. The TPB explained variation in intention well (R2 .54-.60) and some PA behavior (R2 .13-.16). The intervention successfully got participants to exercise independent of the measured TPB concepts. More TPB studies in the context of interventions are needed.

INTRODUCTION: Medical guidelines aim to stimulate stepped care for knee and hip osteoarthritis, redirecting treatments from hospitals to primary care. In the Netherlands, this development was supported by changing health insurance coverage for physio/exercise therapy. The aim of this study was to evaluate healthcare utilization patterns before and after health changes in health insurance coverage. METHOD: We analyzed electronic health records and claims data from patients with osteoarthritis in the knee (N = 32,091) and hip (N = 16,313). Changes between 2013 and 2019 in the proportion of patients treated by the general practitioner, physio/exercise therapist or orthopedic surgeon within 6 months after onset were assessed. RESULTS: Joint replacement surgeries decreased for knee (OR 0.47 [0.41-0.54]) and hip (OR 0.81 [0.71-0.93]) osteoarthritis between 2013-2019. The use of physio/exercise therapy increased (knee: OR 1.38 [1.24-1.53], hip: OR 1.26 [1.08-1.47]). However, the proportion treated by a physio/exercise therapist decreased for patients that had not depleted their annual deductibles (knee: OR 0.86 [0.79 - 0.94], hip: OR 0.90 [0.79 - 1.02]). This might be affected by the inclusion of physio/exercise therapy in basic health insurance in 2018. CONCLUSION: We have found a shift from hospitals to primary care in knee and hip osteoarthritis care. However, the use of physio/exercise therapy declined after changes in insurance coverage for patients that had not depleted their deductibles.

BACKGROUND: up till now, the risk of falls has been expressed as falls incidence (i.e. the number of falls or fallers per 100 person-years). However, the risk of an accident or injury is the probability of having an accident or injury per unit of exposure. The FARE (Falls risk by Exposure) is a measure for falls risk which incorporates physical activity as a measure of exposure. The objective of this study was to compare falls incidence and the FARE when expressing the age-related risk of fall-related injuries. METHODS: data of 21,020 community-dwelling elderly aged ≥55 years (60.3% women) obtained from a national survey (2000-05) were used to compare incidence of fall-related injuries and the FARE. In order to compare both measures, risk ratios (of both outcome measures) were calculated for each age group. Hierarchical regression analyses (linear versus exponential model) were conducted to check the best model fit when expressing falls risk by age for the total study population and for men and women separately. RESULTS: the risk of fall-related injuries, calculated on the basis of the incidence of fall-related injuries, showed a linear relationship with age, whereas the risk calculated on the basis of fall-related injuries corrected for exposure (falls risk by exposure, FARE) showed an exponential relationship. Calculations on the basis of the incidence of fall-related injuries underestimated the risk of fall-related injuries in people aged 70 years and older, and especially in women. CONCLUSION: calculation of the risk of fall-related injuries based on the incidence of these injuries underestimates the risk of such injuries relative to that calculated on the basis of the FARE. FARE-based calculations enable the early identification of people at high risk of falls and provide a more sensitive outcome measure for studies evaluating falls prevention interventions.

BACKGROUND: Common expressions of falls risk do not include exposure to hazards. We compared two expressions: the commonly used population incidence (fallers per 1000 person-years) and the FARE (FAlls Risk by Exposure): the number of fallers per 1000 physically active person-days. METHODS: Prospective follow-up study among community dwelling older persons (N=771) aged between 71 and 96 years in The Netherlands, 2005. Baseline data on age, gender, disabilities (vision, mobility), and number of days per week with minimally 30 min of physical activity were collected. Falls were registered monthly. Falls risk was expressed as the number of falls per 1000 person-years and as the FARE. A balance control difficulty score was based on the sumscore of 11 disability items. RESULTS: Increased difficulty controlling balance was linearly associated with reduced exposure to risky situations (Spearman correlation coefficient=-.56) and to an increased falls risk per 1000 person-years. In contrast, the FARE score increased exponentially, which is more indicative of the real risk people face, taking into account their activity restriction. CONCLUSIONS: The FARE is recommended for use in public health policy and research on falls prevention because it takes into account reduced physical activity of older persons who experience increased difficulty controlling their balance.

This paper presents a study to estimate a preference-based participation index from the Dutch London Handicap Scale (LHS) classification system that can be applied to past or future Dutch LHS data sets. A subset of 60 states were valued by a representative sample of 285 respondents of the Dutch general adult population. Different models were estimated for predicting health state valuations for all 46,656 states defined by the LHS. Several criteria were used for comparison of the different models and for arguing which one is the most preferred model to use. Our data showed that using the English index would give systematic errors for the Dutch population preferences.

OBJECTIVE: Chronic diseases are increasingly prevalent and often occur as multimorbidity. This study compares the impact of musculoskeletal disorders (MSKDs) on health and health care costs with other chronic diseases, and assesses the additional impact of MSKDs on these outcomes when occurring as part of multimorbidity. METHODS: A household survey in a random Dutch population sample (n = 8,904) yielded information on sociodemographics, presence of 9 physician-confirmed chronic diseases (i.e., musculoskeletal, migraine, diabetes mellitus, cardiovascular, cancer, respiratory, skin, mental, and gastrointestinal), physical component summary (PCS) and mental component summary (MCS) scores of the Short Form 12 health survey, and health care utilization. The independent influence of different diseases and the role of MSKDs with increasing number of morbidities on PCS/MCS and 3-month societal health care costs were explored through multivariable linear and zero-inflated negative binomial regressions, respectively. RESULTS: Twenty percent of all subjects and 56% of those with multimorbidity had an MSKD. MSKDs had the largest impact on PCS (ß = -8.37 [95% confidence interval (95% CI) -8.84, -7.89]) but no significant impact on MCS. When MSKDs occurred as part of multimorbidity, an amplification of the adverse effect on PCS but not on MCS was seen, irrespective of the number of comorbidities. MSKDs were responsible for a 2-fold increase in costs (Exp [ß] = 2.27 [95% CI 2.08, 2.51]), which was the second highest cost increase of all diseases (after cancer). Significant amplification of costs was seen when MSKDs co-occurred with mental diseases. CONCLUSION: MSKDs often co-occur with other chronic diseases. In the context of multimorbidity, presence of an MSKD amplifies the impact on physical health, and to a lesser extent on health care costs, but not on mental health.

BACKGROUND: The London Handicap Scale (LHS) was found to be a valid and reliable scale for measuring participation restrictions in adults. OBJECTIVE: This paper describes the development and assesses the construct-related validity of a Dutch version of the London Handicap Scale (DLHS). METHODS: The DLHS was tested in 798 adults (mean age: 50.7 years, SD=14.5, range 16 to 85) and validated with the 'Impact on Participation and Autonomy' (IPA) questionnaire, the Dutch version of the EQ-5D and questions concerning comorbidity and use of medical devices. The study population consisted of patients with rheumatoid arthritis, chronic obstructive pulmonary disease (COPD), epilepsy, laryngectomy and multiple sclerosis. RESULTS: Feasibility was satisfactory. Large correlations (ρ > 0.6) for the DLHS sum score were found with the IPA subscales 'autonomy outdoors', 'perceiving problems', 'family role', autonomy indoors', 'work and education' and with the EQ-5D. The DLHS sum score differs significantly between subgroups based on the number of chronic diseases, number of medical devices and self-reported burden of disease or handicap (p< 0.001). CONCLUSIONS: Based on this evaluation the questionnaire seems feasible and valid for assessing differences in level of participation between subgroups of chronically ill or disabled persons in the Netherlands.

PURPOSE: To report which existing survey instruments assess participation according to the International Classification of Functioning, Disability and Health (ICF). METHOD: A literature search for relevant survey instruments was conducted. Subsequently, survey instruments were evaluated of which the complete questionnaire, published in the English language, was obtained. Items on participation were evaluated according to the ICF, defined as involvement in life situations, including being autonomous to some extent or being able to control your own life. RESULTS AND CONCLUSIONS: Eleven survey instruments were identified, of which nine were evaluated on participation. All of the nine instruments measure participation to some extent. The two instruments closest to solely involve items on participation level are the Perceived Handicap Questionnaire (PHQ) and the London Handicap Scale (LHS). The PHQ is measuring the perception of participation. In the LHS, the items are formulated in terms of participation, while the response categories include all components of the ICF, from problems in body function to participation. Much more discussion is needed to be able to get an unambiguous picture to distinguish between activity and participation.

PURPOSE: Home-based rehabilitation is a promising alternative to regular center-based stroke rehabilitation. The objective of this study was to identify what is currently known about determinants that influence the implementation of home-based stroke rehabilitation (HBSR) in clinical practice. METHODS: A systematic review of determinants of HBSR was conducted, using a framework for innovation (including determinants related to the innovation, the user, the organization, and the socio-political context). Reviews, meta-analyses, and qualitative studies were included. Studies were selected if they concerned: home-based rehabilitation of stroke patient's (motor) function, changes in in-person service delivery (> 24 h to 12 months post-stroke) and determinants of implementation. RESULTS: A total of 88 studies were identified, of which 7 studies met the inclusion criteria. Identified determinants of implementation of HBSR were: intervention effectiveness, the exact nature of the medical condition, satisfaction with services, coordination of services, inter-professional collaborations, availability of appropriate training equipment, and costs. However, none of the studies had the primary aim to identify determinants of implementation. CONCLUSION: A more complete and detailed overview of existing determinants of HBSR is needed to assist professionals and organizations in decision-making on HBSR implementation and development of suitable strategies for implementation. Implications for Rehabilitation Committed professionals and a smooth transfer to the home-environment are essential elements for home-based rehabilitation or early supported discharge. The determinants related to the client include age, needs, stability and severity of the stroke as well as the living conditions. Clients and care givers should be involved in the recovery process including the decision for early discharge and home-based rehabilitation. It is necessary that essential therapy equipment be provided and that the travel times and costs of therapists are reimbursed.

Studies on the use of performance enhancing drugs (PED) in fitness centres rely predominately on conventional survey methods using direct questioning. However, research indicates that direct questioning of sensitive information is characterized by under-reporting. The aim of the present study was to contrast direct questioning of different types of PED use by Dutch fitness centre members with results obtained with the Randomized Response Technique (RRT). Questionnaires were conducted among members of fitness centres. PED were classified into the following categories: anabolic steroids, prohormones, substances to counteract side-effects, growth hormone and/or insulin, stimulants (to reduce weight), and miscellaneous substances. A total of 718 athletes from 92 fitness centres completed the questionnaire. The conventional method resulted in prevalences varying between 0% and 0.4% for the different types of PED with an overall prevalence of 0.4%. RRT resulted in prevalences varying between 0.8% and 4.8% for the different types of PED with an overall prevalence of 8.2%. The overall prevalence of the two survey methods differed significantly. The current study showed that the conventional survey method using direct questioning led to an underestimation of the prevalence. Based on the RRT results, the percentage of users of PED among members of fitness centres is approximately 8.2%. Stimulants to lose weight had the highest prevalence, even higher than anabolic steroids. The key task for future preventive health work is to not only focus on anabolic steroid use, but also include interventions focusing on the use of stimulants to lose weight.

PURPOSE: Physical activity (PA) is an important behavior when it comes to preventing or slowing down disablement caused by aging and chronic diseases. It remains unclear whether PA can directly prevent or reduce disability in activities of daily living (ADL). This article presents a meta-analysis of the association between PA and the incidence and progression of basic ADL disability (BADL). METHODS: Electronic literature search and cross-referencing of prospective longitudinal studies of PA and BADL in community dwelling older adults (50+) with baseline and follow-up measurements, multivariate analysis and reporting a point estimate for the association. RESULTS: Compared with a low PA, a medium/high PA level reduced the risk of incident BADL disability by 0.51 (95% CI: 0.38, 0.68; p<001), based on nine longitudinal studies involving 17,000 participants followed up for 3-10 years. This result was independent of age, length of follow-up, study quality, and differences in demographics, health status, functional limitations, and lifestyle. The risk of progression of BADL disability in older adults with a medium/high PA level compared with those with a low PA level was 0.55 (95% CI: 0.42, 0.71; p<001), based on four studies involving 8500 participants. DISCUSSION: This is the first meta-analysis to show that being physically active prevents and slows down the disablement process in aging or diseased populations, positioning PA as the most effective preventive strategy in preventing and reducing disability, independence and health care cost in aging societies.

BACKGROUND: Many questionnaires for measuring physical activity (PA) exist. This complicates the comparison of outcomes. METHODS: In 8 European countries, PA was measured in random samples of 600 persons, using the IPAQ as a 'bridge' to historical sets of country-specific questions. We assume that a unidimensional scale of PA ability exists on which items and respondents can be placed, irrespective of country, culture, background factors, or measurement instrument. Response Conversion (RC) based on Item Response Theory (IRT) was used to estimate such a common PA scale, to compare PA levels between countries, and to create a conversion key. Comparisons were made with Eurobarometer (IPAQ) data. RESULTS: Appropriateness of IRT was supported by the existence of a strong first dimension established by principal component analysis. The IRT analysis resulted in 1 common PA scale with a reasonable fit and face validity. However, evidence for cultural bias (Differential Item Functioning, DIF) was found in all IPAQ items. This result made actual comparison between countries difficult. CONCLUSIONS: Response Conversion can improve comparability in the field of PA. RC needs common items that are culturally unbiased. Wide-scale use of RC awaits measures that are more culturally invariant (such as international accelerometer data).

Rheumatic disorders concern a broad spectrum of painful disorders affecting the musculoskeletal system, and are responsible for a considerable amount of disease burden and also a substantial economic burden. This economic burden consists of direct and indirect costs, but also the so-called intangible costs. In this study, we estimated the societal cost of rheumatic disorders in the Netherlands, including intangible costs. Data from the National Monitor on Musculoskeletal System 2010 were used to assess resource used, multiplied with standard prices for the Netherlands to obtain total costs for the 1.8 million people suffering from rheumatic disorders. These estimates were supplemented with data from secondary sources. Total societal costs of rheumatic disorders in the Netherlands amount to 4.7 million a year, that is, 2665 per person with rheumatic disorders. Rheumatic disorders have considerable costs, which justify more attention in discussing investments in facing the challenges in our ageing Western societies.

BACKGROUND: The consumption of dairy products (milk, cheese, and butter) has been positively associated with the risk of ischemic heart disease (IHD), stroke, and total mortality because of the saturated fat content of these products; and protective effects against these outcomes have been attributed to the calcium content and low-fat choices of dairy products. However, robust evidence on the net effect of dairy product consumption on mortality is limited. OBJECTIVE: The objective was to investigate the association between dairy product consumption and the risk of death (from all causes, IHD, and stroke) in the Netherlands Cohort Study (NLCS). DESIGN: The NLCS was initiated in 120,852 men and women aged 55-69 y at baseline in 1986. After 10 y of follow-up, 16,136 subjects with complete dietary information had died. Twenty-nine percent (men) and 22% (women) of these deaths were due to IHD or stroke. The validated 150-item food-frequency questionnaire provided detailed information on dairy products. RESULTS: Multivariate survival analyses following a case-cohort approach showed only a few statistically significant, but mostly weak, associations. A slightly increased risk of all-cause and IHD mortality was found for both butter and dairy fat intake (per 10 g/d; rate ratio(mortality): 1.04; 95% CI: 1.01, 1.06) only in women. Fermented full-fat milk was inversely associated with all-cause and nonsignificantly with stroke mortality in both sexes. CONCLUSIONS: The role of dairy product consumption in mortality generally appeared to be neutral in men. In women, dairy fat intake was associated with slightly increased all-cause and IHD mortality. More research is warranted on a possible protective effect of fermented milk on stroke mortality.

BACKGROUND: In their letters to the editor, Lacherez et al. [Lacherez, P.F., Wood, J.M., Kerr, G.K., 2007. Does activity level mediate or suppress the association between fear of falling and falls? Prev. Med. 31; (Electronic publication ahead of print)] and Hafeman and Schwartz [Hafeman, D., Schwartz, S., 2007. Assessing mediation: The necessity of theoretical considerations. Prev. Med. 26; (Electronic publication ahead of print)] questioned the correctness of using the term 'mediation' in our paper [Wijlhuizen, G.J., Jong, R. de, Hopman-Rock, M., 2007. Older persons afraid of falling reduce physical activity to prevent outdoor falls. Prev. Med. 44, 260-264.]. In this paper, we concluded that (outdoor) Physical activity mediates the relationship between Fear of falling and outdoor Falls. We investigated whether the term 'inconsistent mediation' might be a more appropriate term to use in this context. METHODS: Based on literature, we describe the relationship between fear of falling, physical activity, and falls within a causal model. RESULTS: Two causal pathways between Fear and Falls exist, with the causal pathway going from Fear of falling via Physical activity to Falls counteracting (is inconsistent with) the causal pathway going from Fear of falling via Hesitancy to Falls. CONCLUSION: The term 'inconsistent mediation' might be more appropriate to describe the causal relationships between Fear of falling, Falls, and Physical activity.

OBJECTIVES: Most research on falls among older persons focuses on health-related factors that affect the ability to maintain balance. The objective of the study is to determine the association between physical activity and occurrence of falls among community-dwelling older persons. METHODS: The distribution of falls and person-hours of physical activity in the home over 24 h was compared. The falls data (n=501) were extracted from a pooled dataset of three follow-up studies conducted between 1994 and 2005 (n=3587). The 1995 Dutch National Time-Budget Survey provided hour-by-hour information on activities performed by older individuals (n=459) in the home; this sample was representative for the Netherlands. The association between the 24-h distribution of falls and physical activity and the risk of falling (the ratio between the distribution of falls and physical activity) were determined. Participants were community-dwelling older persons aged 65 years and older. RESULTS: More physical activity was positively associated with more falls (Spearman correlation=.89, p<.000). The risk of falling at night (1 a.m.-6 a.m.) was almost eight times higher compared to 7 a.m.-12 p.m. CONCLUSIONS: Physical activity is strongly associated with the number of falls in the home, measured over 24 h. Older persons may be at increased risk of falling if they are encouraged to become more physically active, or if they often get out of bed at night. Thus in addition to health-related factors, changes in level of physical activity should also be taken into account when estimating a person's risk of falling.
