Comparison of the 2010 and 2019 diagnostic criteria for sarcopenia by the European Working Group on Sarcopenia in Older People (EWGSOP) in two cohorts of Swedish older adults.

BACKGROUND: The operational definition of sarcopenia has been updated (EWGSOP2) and apply different cut-off points compared to previous criteria (EWGSOP1). Therefore, we aim to compare the sarcopenia prevalence and the association with mortality and dependence in activities of daily living using the 2010 (EWGSOP1 and 2019 (EWGSOP2 operational definition, applying cut-offs at two levels using T-scores. METHODS: Two birth cohorts, 70 and 85-years-old (n = 884 and n = 157, respectively), were assessed cross-sectionally (57% women). Low grip strength, low muscle mass and slow gait speed were defined below - 2.0 and - 2.5 SD from a young reference population (T-score). Muscle mass was defined as appendicular lean soft tissue index by DXA. The EWGSOP1 and EWGSOP2 were applied and compared with McNemar tests and Cohen's kappa. All-cause mortality was analyzed with the Cox-proportional hazard model. RESULTS: Sarcopenia prevalence was 1.4-7.8% in 70-year-olds and 42-62% in 85 years-old's, depending on diagnostic criteria. Overall, the prevalence of sarcopenia was 0.9-1.0 percentage points lower using the EWGSOP2 compared to EWGSOP1 when applying uniform T-score cut-offs (P <  0.005). The prevalence was doubled (15.0 vs. 7.5%) using the - 2.0 vs. -2.5 T-scores with EWGSOP2 in the whole sample. The increase in prevalence when changing the cut-offs was 5.7% (P <  0.001) in the 70-year-olds and 17.8% (P <  0.001) in the 85-year-olds (EWGSP2). Sarcopenia with cut-offs at - 2.5 T-score was associated with increased mortality (hazard ratio 2.4-2.8, P <  0.05) but not at T-score - 2.0. CONCLUSIONS: The prevalence of sarcopenia was higher in 85-year-olds compared to 70-year-olds. Overall, the differences between the EWGSOP1 and EWGSOP2 classifications are small. Meaningful differences between EWGSOP1 and 2 in the 85-year-olds could not be ruled out. Prevalence was more dependent on cut-offs than on the operational definition.

Dizziness and its association with walking speed and falls efficacy among older men and women in an urban population.

BACKGROUND: Dizziness is common among older people and falling is a feared complication. AIM: The purpose of this study was to investigate the presence of dizziness and its association with falls, walking speed and fear of falling, including sex differences, among 79-year-olds. Secondary purposes were to describe the relationship between dizziness and falls to number of medications and diseases. METHOD: The study consisted of the fifth cohort of Gothenburg's H70 birth cohort studies. A sample of 662 79-year-olds (404 women, 258 men) were investigated with questions regarding dizziness, previous falls and falls efficacy [estimated according to the falls efficacy scale Swedish version (FES (S))]. Functional tests included self-selected and maximal walking speed over 20 m. RESULTS: Dizziness was reported among 51% of the women and by 58% of the men (p = 0.12). Approximately, 40% had fallen during the past 12 months (41% women, 38% of the men, p = 0.48). Dizziness was related to a higher risk of falls among women (OR 2.63 (95% CI 1.67-4.14, p < 0.0001), but not among men (OR 1.07, 95% CI 0.63-1.82, p = 0.8). Dizzy individuals had lower scores on FES (S) (p < 0.01), more medications (p < 0.001) and diseases (p < 0.001) than those without dizziness. Participants who reported dizziness walked 10% slower than participants without dizziness (p < 0.001). CONCLUSION: Women with dizziness more often reported falls compared to women without dizziness-a trend that was not seen among men. Persons with dizziness walked slower. Many medications increased risk of falling; hence, number of medications alone might help pinpoint risk groups for falling.

Physical functioning in older persons with dizziness: a population-based study.

BACKGROUND: Dizziness is one of the most prevalent symptoms in old age and tends to increase with age. AIMS: To report physical functioning, health-related aspects and gender differences in elderly persons with and without dizziness in a population-based sample of 75-year-olds. METHODS: A cross-sectional sample of 75-year-olds from Gothenburg, Sweden (n = 675, 398 women and 277 men) was examined by means of questionnaires and functional tests. The questions concerned dizziness/imbalance, physical activity level, walking habits, falls efficacy, number of falls, subjective health or general fatigue and medication. The tests included were self-selected and maximum gait speed, stair climbing capacity, one leg stance and grip strength. RESULTS: More women than men reported dizziness/imbalance (40 vs 30 %, p < 0.001). Persons with dizziness, compared to those without dizziness, less often regularly exercised at a moderate intensity level (summer: 62 vs 74 %, p < 0.001; winter: 41 vs 51 %, p < 0.001), less often took a daily walk (p < 0.05), had lower scores on the FES(S) (p < 0.001), more often reported general fatigue (p < 0.001), more often had fallen in the previous year (40 vs 23 %, p < 0.001) and had a higher intake of medical drugs (4.6 vs 3.3, p < 0.001). They also performed worse regarding gait speed, stair climbing and one leg stance (p < 0.001), but there was no difference in grip strength. CONCLUSION: Older persons with dizziness are less physically active, have worse lower extremity function, are more often fallers and report lower self-rated health than persons without dizziness.

Long-Term Effects of Individually Tailored Physical Training and Activity on Physical Function, Well-Being and Cognition in Scandinavian Nursing Home Residents: A Randomized Controlled Trial.

BACKGROUND: The preservation of physical functions such as muscle strength, balance and mobility is fundamental to maintaining independence in activities of daily living (ADL). The physical activity level of most nursing home residents is very low, which implies that they are often subject to a decline in health, mobility, autonomy and social contacts and are also at risk of suffering a decline in mental well-being. In a previous study, we demonstrated that transfers, balance and physical activity level improved after 3 months of individually tailored intervention in nursing home residents. OBJECTIVE: To evaluate the long-term effects on ADL, balance function, physical activity level, physical performance, falls-related self-efficacy, well-being and cognitive function 3 months after the completion of our intervention in nursing home residents. METHODS: The study was a multicenter randomized, controlled clinical trial with a parallel-group design. It was conducted in nursing homes in Sweden, Norway and Denmark, with an intervention period lasting 3 months and a follow-up at 6 months. Initially, 322 nursing home residents with a mean age of 85 years were included; 85 from Sweden, 171 from Norway and 66 from Denmark. Of these, 241 [129 intervention group (IG), 112 control group (CG)] were eligible for the 6-month follow-up tests. The level of dependence in ADL, physical activity level, several dimensions of physical function, well-being, falls-related self-efficacy and cognitive function were assessed with reliable and valid instruments at baseline, immediately after 3 months of intervention and 3 months later at the 6-month follow-up. RESULTS: After 3 months of intervention and an additional period of 3 months without intervention, only the following 2 variables demonstrated significant group differences: social and cognitive function, measured by the Functional Independence Measure n-r, where the IG deteriorated while the CG was almost stable. However, regarding transfers, the IG deteriorated significantly less than the CG. CONCLUSION: Without supervised physical exercise that challenged the individuals' capability, gains in ADL function, balance and transfer ability deteriorated during the 3 months following the intervention period. Thus, continuous, individually adjusted and supported physical activity seems crucial for the maintenance of physical functions in these vulnerable elderly persons.

Secular trends in frailty: a comparative study of 75-year olds born in 1911-12 and 1930.

BACKGROUND: while there is a trend towards a compression of disability, secular trends in physiological frailty have not been investigated. The aim of this paper was to report physiological frailty in two cohorts of 75-year olds examined in 1987 and 2005. METHODS: a repeated cross-sectional study : Two population-based birth cohorts of community-dwelling 75-year olds from Gothenburg, Sweden, born in 1911-12 (n = 591) and 1930 (n = 637) were examined with identical methods in 1987 and 2005. Measures were three frailty criteria from Fried's frailty phenotype: low physical activity, slow gait speed and self-reported exhaustion. RESULTS: seventy-five-year olds examined in 2005 were less frail according to the criteria low physical activity compared with those examined in 1987 (3 versus 18%, P < 0.001).This was seen both in women and in men, and among those with basic and more than basic educational level. Further, men with basic education were less frail in 2005 compared with those in 1987 in slow gait speed (non-significant when adjusted for body height) and low self-rated fitness, while no cohort differences were seen in men with more than basic education. Women with more than basic education were less frail in 2005 compared with those in 1987 in slow gait speed and self-rated fitness, while no cohort difference was seen in women with basic education. CONCLUSION: less 75-year olds were physiologically frail in 2005 compared with those in 1987, with the exception of women with low educational level, suggesting that this is a disadvantaged group that needs to receive particular attention with regard to physiological frailty.

Health-related quality of life in relation to walking habits and fitness: a population-based study of 75-year-olds.

PURPOSE: To assess health-related quality of life (HRQL) in relation to walking habits and fitness status in older persons. A second aim was to examine fitness status as a mediator in the relation between walking habits and HRQL. METHODS: A cross-sectional population-based sample of 75-year-olds from Gothenburg, Sweden, was examined (n = 698, response rate 61 %). Walking habits were assessed as weekly frequency and duration. HRQL was assessed with the Short Form-36 (SF-36) and fitness with maximal and self-selected gait speed, chair-stand, stair-climbing capacity, grip strength and one-leg stance. RESULTS: The proportion of 75-year-olds who attained recommended levels of moderate physical activity (≥ 150 min/week), described as walking, was 60 %. This was positively associated with most subscales of SF-36 and with all fitness tests except grip strength. Maximal gait speed was the fitness test with the highest correlations to all SF-36 subscales. Fitness, described with maximal gait speed, was a partial mediator in most relations between walking habits and SF-36. After adjustment for confounders, associations between regular walking and SF-36 were no longer significant, except for Role Physical, General Health and Role Emotional in women. CONCLUSIONS: Attaining recommended levels of walking, as well as a high fitness status, is positively associated with several aspects of HRQL in older persons. Fitness, described with maximal gait speed, seems to have a partial role in the relation between walking habits and HRQL, suggesting that other mechanisms are also involved.

Effects of individually tailored physical and daily activities in nursing home residents on activities of daily living, physical performance and physical activity level: a randomized controlled trial.

BACKGROUND: Nursing home residents are extremely inactive and deterioration in health and an increasing dependence in activities of daily living (ADL) are common. Physical activity and exercise play a major role in the preservation of physical function and quality of life late in life. However, evidence for the benefit of rehabilitation in nursing home residents is conflicting and inconclusive. OBJECTIVE: To evaluate the effect of an individually tailored intervention program of 3 months, for nursing home residents, on ADL, balance, physical activity level, mobility and muscle strength. METHODS: In this single-blind randomized clinical trial with parallel groups, nursing home residents >64 years of age from three Nordic countries were included. The intervention group (IG) was assigned to individually tailored physical and daily activities, while the control group (CG) received ordinary care. Primary outcomes were ADL and balance, and secondary outcomes physical activity level, mobility and muscle strength. RESULTS: At baseline, 322 nursing home residents were included, of whom 266 were assessed after 3 months of intervention. Following the intervention, a significant difference was found between participants in the IG and CG on measures of balance, physical activity and transfers. The IG significantly improved walking/wheelchair speed and functional leg muscle strength. The CG had significantly deteriorated in ADL, balance and transfers. Persons who had taken part in the intervention for more than 150 min/week significantly improved their balance and physical activity level. Participation in more than 10 weeks of intervention significantly improved physical activity and walking/wheelchair speed, while a deterioration was seen in those who had participated less. CONCLUSION: Individually tailored intervention in nursing home residents focusing on physical and daily activities is effective in improving transfers, balance and physical activity level compared to usual care. The effect of the intervention is dependent on the total activity time.

Performance-based physical function in older community-dwelling persons: a systematic review of instruments.

BACKGROUND: Identification of older persons at risk for the loss of independence, onset of (co)-morbidity or functional limitations through screening/assessment is of interest for the public health-care system. To date several different measurement instruments for overall physical function are frequently used in practice, but little information about their psychometric properties is available. Objectives and METHODS: Our aim was to assess instruments with an overall score related to functional status and/or physical performance on content and psychometric properties. Electronic databases (Medline, EMBASE, AMED, Cochrane Library and CINAHL) were searched, using MeSH terms and relevant keywords. Studies, published in English, were included if their primary or secondary purpose was to evaluate the measurement properties of measurement instruments for overall physical function in community-dwelling older persons aged 60 years and older. Reliability, validity, responsiveness and practicability were evaluated, adhering to a specified protocol. RESULTS: In total 78 articles describing 12 different functional assessment instruments were included and data extracted. Seven instruments, including their modified versions, were evaluated for reliability. Nine instruments, including their modified versions, were evaluated with regard to validity. CONCLUSION: In conclusion, the Short Physical Performance Battery can be recommended most highly in terms of validity, reliability and responsiveness, followed by the Physical Performance Test and Continuous Scale Physical Functional Performance.

Benign paroxysmal positional vertigo is a common cause of dizziness and unsteadiness in a large population of 75-year-olds.

BACKGROUND AND AIMS: Studies have shown that 65% of people with dizziness may have a vestibular etiologic diagnosis, possibly benign paroxysmal positional vertigo (BPPV). The diagnosis of BPPV is based on medical history and findings after the Dix-Hallpike test. It is sometimes difficult to perform the Dix-Hallpike test in elderly persons, due to the limited range of motion when extending the neck. In this study, we used a side-lying test to stimulate the posterior semicircular canal, while the head and neck were fully supported on the examination table. The aims of this study were to investigate the prevalence of dizziness and/or impaired balance and BPPV in a population of 75-year-olds by means of a questionnaire and clinical tests, and to compare elderly persons with and without BPPV. METHODS: A representative population sample of 675 persons completed a questionnaire about dizziness and 571 persons underwent side-lying, static balance and dynamic walking tests. RESULTS: Subjective dizziness and/or impaired balance were found in 36% of subjects, especially when walking outdoors. A significant gender difference was found, with a higher prevalence in women (40%) compared with men (30%) (p<0.01). BPPV was found in 11% and was significantly more common in women (p<0.01). Elderly individuals with BPPV also displayed significantly impaired balance in static and dynamic balance tests compared with persons without BPPV (p<0.01). Persons with BPPV reported significantly more sub- jective problems with dizziness and balance compared with persons without BPPV (p<0.001). CONCLUSIONS: Subjective and objective unsteadiness, dizziness and BP- PV are common in the elderly.

Policy assessment and policy development for physical activity promotion: results of an exploratory intervention study in 15 European nations.

BACKGROUND: Purpose of the study was to test a theoretical model to assess and develop policies for the promotion of physical activity among older people as part of an international intervention study. METHODS: 248 semi-standardized interviews with policy-makers were conducted in 15 European nations. The questionnaire assessed policy-makers' perceptions of organizational goals, resources, obligations, as well as organizational, political and public opportunities in the area of physical activity promotion among older people. In order to develop policies, workshops with policy-makers were conducted. Workshop outputs and outcomes were assessed for four nations nine months after the workshops. RESULTS: Policy assessment: Results of the policy assessment were diverse across nations and policy sectors. For example, organizational goals regarding actions for physical activity promotion were perceived as being most favorably by the sports sector. Organizational obligations for the development of such policies were perceived as being most favorably by the health sector. Policy development: The workshops resulted in different outputs: a national intersectoral action plan (United Kingdom), a national alliance (Sweden), an integrated policy (the Netherlands), and a continuing dialogue (Germany). CONCLUSIONS: Theory-driven policy assessment and policy-maker workshops might be an important means of scientific engagement in policy development for health promotion.

Long-term effects of home rehabilitation after hip fracture - 1-year follow-up of functioning, balance confidence, and health-related quality of life in elderly people.

PURPOSE: To investigate the long-term effects of home rehabilitation (HR) after hip fracture in elderly people. METHOD: A randomized, controlled longitudinal study on geriatric hospital-based HR was compared with conventional care (CC) in 102 patients. Independence in activities of daily living (ADL), frequency of activity, basic physical performance, balance confidence, health-related quality of life, mood and perceived recovery were measured 6 and 12 months after discharge. RESULTS: One year post-discharge the HR participants reported significantly higher degree of independence in self-care and locomotion, as well as of balance confidence in stairs and instrumental activities and perceived physical function, than the CC group. One year after discharge 14 persons (29%) in the HR group and five persons (9%) in the CC group considered themselves fully recovered. CONCLUSIONS: The positive long-term effects were more pronounced among the participants in the HR group than among those who received CC, possibly due to the early start of the HR programme in hospital and its focus on self-efficacy and training of daily activities. However, one year after discharge a mojority of participants in both groups did not consider themselves to be fully recovered when they compared to their situation before the fracture.

A structural equation model of the relation between socioeconomic status, physical activity level, independence and health status in older Iranian people.

BACKGROUND AND AIM: Health status is an independent predictor of mortality, morbidity and functioning in older people. The present study was designed to evaluate the link between socioeconomic status (SES), physical activity (PA), independence (I) and the health status (HS) of older people in Iran, using structural equation modelling. METHODS: Using computerized randomly selection, a representative sample of 851 75-year-olds living in Tehran (2007-2008), Iran, was included. Participants answered questions regarding indicators of HS, SES and also PA and I through interviews. Both measurement and conceptual models of our hypotheses were tested using Mplus 5. Maximum-likelihood estimation with robust standard errors (MLR estimator), chi-square tests, the goodness of fit index (and degrees of freedom), as well as the Comparative Fit Index (CFI), and the Root Mean Square Error of Approximation (RSMEA) were used to evaluate the model fit. RESULTS: The measurement model yielded a reasonable fit to the data, χ2=110.93, df=38; CFI=0.97; RMSEA=0.047, with 90% C.I.=0.037-0.058. The model fit for the conceptual model was acceptable; χ2=271.64, df=39; CFI=0.91; RMSEA=0.084, with 90% C.I.=0.074-0.093. SES itself was not a direct predictor of HS (ß=0.13, p=0.059) but it was a predictor of HS either through affecting PA (ß=0.31, p<0.001) or I (ß=0.57, p<0.001). CONCLUSION: Socioeconomic status appeared to influence health status, not directly but through mediating some behavioral and self-confidence aspects including physical activity and independence in ADL.

Association between APOE Genotype and Change in Physical Function in a Population-Based Swedish Cohort of Older Individuals Followed Over Four Years.

The association between decline in physical function and age-related conditions, such as reduced cognitive performance and vascular disease, may be explained by genetic influence on shared biological pathways of importance for aging. The apolipoprotein E (APOE) gene is well-known for its association with Alzheimer's disease, but has also been related to other disorders of importance for aging. The aim of this study was to investigate possible associations between APOE allele status and physical function in a population-based longitudinal study of older individuals. In 2005, at the age of 75, 622 individuals underwent neuropsychiatric and physical examinations, including tests of physical function, and APOE-genotyping. Follow-up examinations were performed at age 79. A significantly larger decline in grip strength (p = 0.015) between age 75 and 79 was found when comparing APOE 𝜀4 allele carriers with non-carriers [10.3 (±10.8) kg versus 7.8 (±10.1) kg]. No association was seen with decline in gait speed, chair-stand, or balance. The association with grip strength remained after correction for cognitive and educational level, depression, cardiovascular disease, stroke, and BMI.

Physical training in institutionalized elderly people with multiple diagnoses--a controlled pilot study.

Reduction in muscle mass and physical function depends on a variety of interacting factors: age, physical activity level, nutritional state and the type and impact of disease. The aim of this study was to investigate the effect of an individualized moderate intensity physical training program on muscle strength, balance, mobility, ambulation and activities of daily living (ADL) in institutionalized elderly people aged 65 and over with multiple diagnoses. Baseline assessments consisted of strength, balance, mobility/ambulation, and ADL. Twenty-one subjects were included in the intervention program. A control group (21 subjects) was first matched in pairs according to gender, age, ADL and mobility, and then by balance, ambulation and strength. The intervention program was individualized and included strength, mobility, balance and endurance training. Follow-up measures were conducted directly after the intervention and 10 weeks later. After drop-out, 20 subjects in the intervention group and 15 subjects in the control group remained for analyses. Balance and mobility improved significantly in the intervention group while declining in the control group. This pilot study indicates that a physical training program may improve functional capacity for institutionalized elderly persons with multiple diagnoses.

Walking ability and activity level after hip fracture in the elderly--a follow-up.

OBJECTIVE: The purpose of this study was to investigate which variables can predict walking ability and activity level 1 year after hip fracture and to describe changes over time regarding functional capacity. SUBJECTS: One hundred and fifty-seven patients (111 women, 46 men), mean age 80.9 (SD 9.5) years, operated on for hip fracture, and able to participate either fully or to some extent in performance tests approximately 1 week after operation were included. Due to high mortality and fragility, only 57 patients participated in the 1-year follow-up. DESIGN AND METHODS: The patients were tested at discharge regarding physical performance, pain and bone mineral density. Status before fracture was evaluated by means of interview. At the 1-year follow-up, patients were also asked about their activities outside the home. A stepwise logistic regression was used for prediction. RESULTS: The patients had a significantly faster walking speed and better balance function after 1 year than before. The test "Timed up and go" was a strong predictor for both walking ability and activity level 1 year after hip fracture. Knowledge about the patient's walking habits outdoors before hip fracture and the degree of independent walking before hip fracture strengthened the prediction.

A behavioral medicine intervention for older women living alone with chronic pain - a feasibility study.

BACKGROUND: To be an older woman, live alone, have chronic pain, and be dependent on support are all factors that may have an impact on daily life. One way to promote ability in everyday activities in people with pain-related conditions is to use individualized, integrated behavioral medicine in physical therapy interventions. How this kind of intervention works for older women living alone at home, with chronic pain, and dependent on formal care to manage their everyday lives has not been studied. The aim was to explore the feasibility of a study and to evaluate an individually tailored integrated behavioral medicine in physical therapy intervention for the target group of women. MATERIALS AND METHODS: The study was a 12-week randomized trial with two-group design. Primary effect outcomes were pain-related disability and morale. Secondary effect outcomes focused on pain-related beliefs, self-efficacy for exercise, concerns of falling, physical activity, and physical performance. RESULTS: In total, 23 women agreed to participate in the study and 16 women completed the intervention. The results showed that the behavioral medicine in physical therapy intervention was feasible. No effects were seen on the primary effect outcomes. The experimental intervention seemed to improve the level of physical activity and self-efficacy for exercise. Some of the participants in both groups perceived that they could manage their everyday life in a better way after participation in the study. CONCLUSION: Results from this study are encouraging, but the study procedure and interventions have to be refined and tested in a larger feasibility study to be able to evaluate the effects of these kinds of interventions on pain-related disability, pain-related beliefs, self-efficacy in everyday activities, and morale in the target group. Further research is also needed to refine and evaluate effects from individualized reminder routines, support to collect self-report data, safety procedures for balance training, and training of personnel to enhance self-efficacy.

Walking habits and health-related factors in 75-year-old Iranian women and men.

An active life style can postpone the aging process, prevent many aspects of functional decline and improve health and quality of life. The aim of this study was to compare elderly people who walked at least 30 min a day with others who walked less, from a gender perspective, regarding perceived health and fitness, physiological capacity and functional performance. A representative sample of 75-year-olds born 1932-33 and living in Tehran, in 2007-2008 was included by randomly selecting 1100 subjects from the latest Iranian census records (1996) by the Statistical Centre of Iran using computerized methods. Participants answered questions regarding health status and physical activity and performed functional tests. Better results for Walkers were observed in most subjective and objective outcome measures. Walkers were less likely to feel generally tired, more likely to have better physical fitness and to have the maximum score on the Falls Efficacy Scale, less likely to feel unstable during walking outdoors and less likely to be dependent or unsafe in ADL. Walkers of both genders performed better in the following tests: chair stand, one leg stance, maximal walking speed and six min walking. The difference between Walkers and Non-Walkers was greater in men. In general, older women and men who walked at least 30 min daily/almost daily showed better results in most health-related outcomes, ADL and functional performance than people who walked less. This study showed gender differences in the level of physical activity and functioning that must be taken into account when planning intervention programs.

Self-respect through ability to keep fear of frailty at a distance: successful ageing from the perspective of community-dwelling older people.

With population ageing, there is an increased interest in how to promote a good old age. A predominant concept in these discussions is successful ageing, which is mainly based on researchers' definitions. This article aims to explore successful ageing from the perspective of community-dwelling older people (24 persons aged 77-90 years). Individual open interviews were conducted and analysed according to qualitative content analysis. An overarching theme was formulated as "self-respect through ability to keep fear of frailty at a distance". This embraced the content of four categories: "having sufficient bodily resources for security and opportunities", "structures that promote security and opportunities", "feeling valuable in relation to the outside world", and "choosing gratitude instead of worries". Ageing seems to be a dynamic process rather than a static structure and might therefore be susceptible to actions. Paying attention to attitudes and treating the older person with respect, particularly with regard to worries about increasing vulnerability, can lead to better ways of promoting successful ageing.

Physical activity and physical functioning in Swedish and Iranian 75-year-olds - a comparison.

BACKGROUND AND PURPOSE: The pattern of population aging is highly complex and contextually based. Cross-national comparisons are helpful to explore related factors. Two cross-sectional studies designed to compare physical activity level, physical functioning and certain health related factors in 75-year-old women and men in Sweden and Iran. MATERIALS AND METHODS: Cohorts of 637 Swedish and 851 Iranian 75-year-olds were investigated with the same methods regarding physical activity level, physical functioning and health related factors. RESULTS: There were differences in physical activity level (p<0.001), self-reported physical functioning (p<0.001) objective physical functioning (p<0.001), health status (p<0.001) and most socio-demographic aspects between the two countries. Here the Swedish cohort had the advantage. There was no difference between the countries regarding prevalence of vertigo or falls. The only variables where the Iranian cohort had advantage over the Swedes were grip strength and smoking habits. There were larger gender differences in walking habits, self-selected walking speed, timed chair stand, and one-leg stance in Iran, and in grip strength in Sweden, all to the disadvantage of women. CONCLUSIONS: Iranian 75-years-olds had a lower physical activity level, a worse lower extremity physical function but a better grip strength, a worse physical health status, but smoked less than their Swedish counterparts. Despite this, there were no differences regarding vertigo or falls. In most aspects, the magnitude of gender differences was about the same and in disadvantage of women, although there were larger differences in Iran in some lower extremity functions.

Functional level, physical activity and wellbeing in nursing home residents in three Nordic countries.

BACKGROUND AND AIMS: The main aim of this study was to describe physical and cognitive function and wellbeing among nursing home residents in three Nordic countries. A second aim was to compare groups of differing ages, levels of dependency in daily life activities (ADL), degree of fall-related self-efficacy, wellbeing and cognitive function. METHODS: 322 residents from nursing homes in Sweden, Norway and Denmark were included. Physical and cognitive function, level of physical activity and wellbeing were assessed by means of reliable and valid instruments. RESULTS: The mean age of participants was 85 years. Sixty percent could rise from a chair and 64% could walk independently. Men were younger and more physically active than women. Participants with a high level of dependency in ADL had lower physical and cognitive functions, were less physically active, and had lower fall-related self-efficacy than participants less dependent in ADL. Participants with low cognitive function had high fall-related self-efficacy. CONCLUSIONS: These data demonstrate that elderly residents in nursing homes in Sweden, Norway and Denmark are frail but heterogeneous. Significant differences in physical activity, physical function and dependency in ADL were seen in relation to age, fall-related self-efficacy, wellbeing and cognitive function.
