Prevalence of disability in a composite ≥75 year-old population in Spain: a screening survey based on the International Classification of Functioning

The Sociodemographic Factors Related to Disability of Applicants of Welfare Benefits in Greece: A Cross-Sectional Survey Based on the World Health Organization Disability Assessment Schedule (WHODAS) 2.0

INTRODUCTION

The aim of the present study was to report on the prevalence of disability and its association with sociodemographic factors among welfare benefit applicants in Greece. The study also compared the disability scores between different health conditions using the WHODAS 2.0 (12-item version), a biopsychosocial-model-based measure.

METHODS

The Greek WHODAS 2.0, 12-item version, was administered by interview. A three-member medical committee assessed the medical records of the applicants and assigned a disability percentage based on the biomedical measure of disability percentage determination (Barema scale).

RESULTS

The majority of the participants were female (56.65%). Certain health conditions were presented more frequently among welfare benefit applicants (mental health disorders and neoplasms). The domains with the highest rate of difficulty were the "participation" and "life activities" domains. Significant differences were found between WHODAS 2.0 and Barema scores for all eight different health condition categories. The factorial ANOVA (8x2) showed a significant interaction effect between health condition category and gender with respect to the WHODAS 2.0 score (F = 19.033, p <.001, η2 = 0.13). The WHODAS 2.0 score was negatively correlated to gender, years of studies, and marital status and positively correlated to age, working status, and the Barema score. The results revealed that male participants with a partner who were younger, had more studies, were actively working, and had a lower Barema score would have lower WHODAS scores.

CONCLUSION

Sociodemographic characteristics of welfare benefit applicants are associated with disability levels based on WHODAS 2.0. Certain health conditions, like mental health or neuromusculoskeletal conditions, are associated with higher disability scores. There are differences between the biopsychosocial and the biomedical approaches to disability assessment. The implementation of WHODAS 2.0 may contribute to a better understanding of the lived experience of patients and is a feasible and efficient tool. Combining biomedical and biopsychosocial approaches may enhance the procedures of disability assessment and help in the development of policies that support people with disabilities.

Associations among quality of life, activities, and participation in elderly residents with joint contractures in long-term care facilities: a cross-sectional study

BACKGROUND

Joint contractures and degenerative osteoarthritis are the most common joint diseases in the elderly population, can lead to limited mobility in elderly individuals, can exacerbate symptoms such as pain, stiffness, and disability, and can interfere with social participation and quality of life, thus affecting mental health. However, relevant studies on this topic are very limited. This study describes the associations of joint contracture categories and sites in elderly residents in long-term care facilities with their quality of life, activities, and participation.

METHODS

Elderly individuals with joint contractures who were residents in long-term care facilities were recruited. The World Health Organization (WHO) Quality of Life and the WHO Disability Assessment Schedule 2.0 were used to survey the participants. Correlations, multiple linear regressions, and multiple analyses of variance, with joint contractures as the response variable, were used in the statistical analysis.

RESULTS

The final statistical analysis included 232 participants. The explanatory power of contracture sites on activities and participation had a moderate strength of association (η2 = .113). Compared with elderly residents with joint contractures and osteoarthritis isolated to the upper limbs, those with joint contractures and osteoarthritis in both the upper and lower limbs had significantly worse activity and participation limitations. No significant differences in activity and participation were found between elderly residents with joint contractures affecting only the upper limbs and those with joint contractures affecting only the lower limbs (F1,226 = 2.604 and F1,226 = 0.674, nonsignificant). Osteoarthritis had the greatest impact on activity limitations and participation restrictions among elderly residents with joint contractures affecting both the upper and lower limbs (F1,226 = 6.251, p = .014).

CONCLUSIONS

Elderly residents in long-term care facilities belonging to minority groups, with a history of stroke, and with osteoarthritis are at a high risk of developing activity limitations and participation restrictions. Moreover, compared with other contraction sites, regardless of osteoarthritis, joint contractures affecting both the upper and lower limbs were associated with the greatest activity limitations and participation restrictions.

TRIAL REGISTRATION

This study has been registered in the Chinese Clinical Trial Registry, registration number and date: ChiCTR2000039889 (13/11/2020).

Psychometric validation of the Chinese version of the PaArticular Scales among elderly residents in long-term care facilities with joint contractures

Background

Joint contractures, which affect activity, participation, and quality of life, are common complications of neurological conditions among elderly residents in long-term care facilities. This study examined the reliability and validity of the Chinese version of the PaArticular Scales in a population with joint contractures.

Methods

A cross-sectional study design was used. The sample included elderly residents older than 64 years with joint contractures in an important joint who had lived at one of 12 long-term care facilities in Taiwan for more than 6 months (N = 243). The Chinese version of the PaArticular Scales for joint contractures was generated from the English version through five stages: translation, review, back-translation, review by a panel of specialists, and a pretest. Test-retest reliability, internal consistency reliability, construct validity, and criterion validity were evaluated, and the results were compared with those for the World Health Organization Quality of Life scale and the World Health Organization Disability Assessment Schedule.

Results

The Chinese version of the PaArticular Scales had excellent reliability, with a Cronbach α coefficient of 0.975 (mean score, 28.98; standard deviation, 17.34). An exploratory factor analysis showed three factors and one factor with an eigenvalue > 1 that explained 75.176 and 62.83 % of the total variance in the Activity subscale and Participation subscale, respectively. The subscale-to-total scale correlation analysis showed Pearson correlation coefficients of 0.881 for the Activity subscale and 0.843 for the Participation subscale. Pearson’s product-moment correlation revealed that the correlation coefficient (r) between the Chinese version of the PaArticular Scales and the World Health Organization Disability Assessment Schedule was 0.770, whereas that for the World Health Organization Quality of Life scale was − 0.553; these values were interpreted as large coefficients.

Conclusions

The underlying theoretical model of the Chinese version of the PaArticular Scales functions well in Taiwan and has acceptable levels of reliability and validity. However, the Chinese version must be further tested for applicability and generalizability in future studies, preferably with a larger sample and in different clinical domains.

Severity Levels of Disability Among Older Adults in Low- and Middle-Income Countries: Results From the Study on Global Ageing and Adult Health (SAGE)

Background: Recent studies suggest the importance of distinguishing the severity levels of disability in the older adult population. However, there is still no consensus regarding an optimal classification. Few studies have estimated the prevalence of severe disability, and the results have been confined to high-income countries. There is no evidence for low- and middle-income countries (LMICs). Therefore, the aim of this study was to provide estimates of the levels of severity associated with disability in older adult populations in LMICs and to examine their relationship with health and socioeconomic factors. Methods: We used data from the Study on global AGEing and adult health (SAGE), wave 1 (2007-2010). Nationally representative samples of adults over 50 years from China, Ghana, India, Mexico, Russian Federation, and South Africa were analyzed (n = 33,641). We measured disability using the World Health Organization Disability Assessment Instrument version 2.0 (WHODAS 2.0). Disability levels according to severity were identified through the use of latent class analysis. Socioeconomic and health factors associated with severe disability were estimated using ordinal logistic regression models. Results: We identified four groups of older adult: (1) without disability, 43.4%; (2) mild disability, 33.3%; (3) moderate disability, 15.3%; and (4) severe disability, 8.0%. These results were heterogeneous for the six countries analyzed. Education and socioeconomic status were significantly associated with severe disability along with the following chronic conditions: angina, arthritis, asthma, cataracts, chronic obstructive pulmonary disease, depression, diabetes, and stroke. Severe disability was also associated with the frailty status, sarcopenia, and mild cognitive impairment. Conclusions: In this study, we estimated severity levels of disability for the older adult population in LMICs. Our results show that severe disability affects 8% of older adult, and that there are important socioeconomic and health factors associated with this condition. Measuring the severity of disability is a critical element to study the causes and consequences of aging. Moreover, the identification of older adult with severe disability is vital to design prevention programs, modify interventions, or develop enabling environments.

Prevalence of Older Adult Disability and Primary Health Care Responsiveness in Low-Income Communities

In Brazil and in most low- and middle-income countries (LMICs), information about how prepared the health care system is for the rapid aging of the population is scarce. We investigated the prevalence of disability and areas of life affected by disability among elders of the public primary health care in São Paulo and Manaus, Brazil. We investigated whether people with disability visited a primary care professional more frequently, the individual characteristics associated with disability, and differences by city. We randomly selected participants aged ≥60 years (n = 1375). The main outcome was disability, evaluated with the 12-item World Health Organization Disability Assessment Schedule (WHODAS 2.0). Exposure variables were consultation with a family physician, sociodemographic characteristics, health status, social support, and lifestyle. The prevalence of global disability was higher in Manaus (66.2% vs. 56.4% in São Paulo). In both cities, participation and mobility were the areas of life most affected by disability. The number of consultations with a family physician was not associated with disability. The high prevalence of disability and associated risk factors indicates that public primary health care is not meeting the needs of elders in both cities. It is warning because most elders in LMICs live in more underserved communities compared to Brazil.

Comparing Activity and Participation between Acquired Brain Injury and Spinal-Cord Injury in Community-Dwelling People with Severe Disability Using WHODAS 2.0

Central-nervous-system (CNS) injuries constitute a significant cause of morbidity (often resulting in long-term disability) and mortality. This cross-sectional study compared the activity and participation of community-dwelling people with severe disability from acquired brain injuries (ABI) (n = 322) and spinal-cord injuries (SCI) (n = 183) to identify risk factors related to disability. Data were collected through a questionnaire survey of community-dwelling people with severe disability attending 65 healthcare centers. The survey included the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) and sociodemographic factors. We categorized a registered grade of disability of 1 or 2 as severe disability. WHODAS 2.0 domain and summary scores were compared between the ABI and SCI groups, and risk factors associated with disability were identified through regression analysis. ABI participants had significantly higher disability in cognition and relationships, whereas patients with SCI had higher disability in mobility (p < 0.05). Onset duration was negatively correlated with cognition, relationships, participation, and summary scores in ABI participants (p < 0.05). Neither group’s socioeconomic factors were associated with WHODA 2.0 scores. Understanding the different patterns of disability between SCI and ABI in community-dwelling people with severe disability helps establish future plans for the management of health resources.

Frail Phenotype and Disability Prediction in Community-Dwelling Older People: A Systematic Review and Meta-Analysis of Prospective Cohort Studies

BACKGROUND

The World Health Organization has identified frailty as a crucial factor affecting successful aging. Systematic literature reviews have yet to focus on the relationship between stages of frailty and disability in community-dwelling older adults.

PURPOSE

The purpose of this study was to investigate the relationships between various frailty types and disability in community-dwelling older adults and to explore how various frailty criteria have been used to assess disability in this population.

METHODS

A systematic literature review and meta-analysis were conducted on articles from the following databases: Cochrane Library, CINAHL, PubMed, and Ovid. Database search criteria included articles that were published between January 2001 and July 2017 and study samples that included community-dwelling adults aged 60 years and older. We excluded studies that were conducted in institutions or hospitals and experimental studies on frailty. Two reviewers independently assessed eligibility and extracted data. A random-effects model was used to analyze the literature and to calculate the pooled disability of frailty.

RESULTS

In total, nine studies with a total sample of 32,998 participants that recorded 8,666 disabilities and a mean follow-up time of 30.4 months (SD = 29.26) were pooled for the meta-analysis. Using various indicators to predict the risk of disability compared with robust older adults, those with frailty faced a higher risk of disability, followed by older adults at risk of frailty.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

Frailty is a crucial health consideration among older adults. Those who are frail have the highest relative risk of disability, followed by those at risk of frailty. Early assessment of frailty may effectively prevent the occurrence of frailty-induced disability in older adults.

Prevalence of disability and its association with sociodemographic factors and quality of life in a rural adult population of northern India

Background

Globally, around 1 billion persons are disabled as per the WHO report on disability in 2011. The bio-psycho-social model of disability was developed by the WHO as the International Classification of Functioning, Disability and Health. We studied the prevalence of disability and its association with sociodemographic factors and quality of life among adults in a rural area.

Methods

We did a community-based, cross-sectional study among 418 randomly selected adult participants aged 18 years and above in a rural area of Ballabgarh, Haryana. Participants were interviewed by administering WHO Disability Assessment Schedule 2.0 (WHODAS 2.0) for assessing disability and WHO Quality of Life-BREF (WHOQOL-BREF) scale for assessing quality of life. Multivariate analyses were done for the predictors of disability. Correlation was applied to find the association between disability and quality of life.

Results

The prevalence of disability was 7.7% (95% confidence interval [CI]: 5.3%-10.6%) based on the cut-off > 40 summary score. More women (10.9%) than men (4.1 %) were disabled (p = 0.009). Being ≥60 years of age was independently associated with disability (adjusted odds ratio 12.3; 95% CI 4.45-33.97). The mean (SD) of the WHOQOL-BREF health-related quality of life (HRQOL) summary score was 67.6 (11.6) and the median was 66.43. HRQOL summary scores decreased as age increased. There was a negative correlation between summary scores of WHODAS 2.0 and WHOQOL-BREF (r -0.57, p<0.001).

Conclusion

Prevalence of disability was higher than the estimate given by Census 2011. The elderly and women experience more disability. As age increases, quality of life decreases. Increase in the level of disability decreases the quality of life.

R, Kalaivani M, Nongkynrih B, Kant S, Gupta SK. Disability and its association with sociodemographic factors among elderly persons residing in an urban resettlement colony, New Delhi, India

Disability prevents an individual from performing to the fullest potential. It is multidimensional. Disability may be physical, mental, social, personal, and environmental or a combination of these. The elderly experience an increased burden of disability, especially in areas where there are limited resources and rapid urbanization. Comparison of reported disability is difficult because several definitions and scales are in use. We used the World Health Organization Disability Assessment Schedule version 2.0 (WHODAS 2.0) to study the prevalence of disability, and its association with sociodemographic factors among elderly persons residing in an urban resettlement colony, New Delhi, India. The WHODAS 2.0 provides continuous summary scores, where higher scores indicate higher disability, and vice versa. Elderly persons aged 60 years and above were selected by simple random sampling in this community-based cross-sectional study. Trained interviewers administered the semi-structured interview schedule and WHODAS 2.0. The prevalence of disability was 7.4% (5.8% - 9.3%) among the 931 participants. The prevalence was higher among females than males. Female sex, elderly aged 70 years and above, and those who were illiterate had increased risk of higher disability scores. Participants who were in government or private service had 50% decreased risk of having higher disability scores. The burden of disability was high among elderly persons residing in this resettlement colony. Community-based holistic interventions are required to mitigate the disability, and to improve the functioning of elderly persons.

The ICF has made a difference to functioning and disability measurement and statistics

AIMS

Fifteen years after the publication of the International Classification of Functioning, Disability and Health (ICF), we investigated: How ICF applications align with ICF aims, contents and principles, and how the ICF has been used to improve measurement of functioning and related statistics.

METHODS

In a scoping review, we investigated research published 2001-2015 relating to measurement and statistics for evidence of: a change in thinking; alignment of applications with ICF specifications and philosophy; and the emergence of new knowledge.

RESULTS

The ICF is used in diverse applications, settings and countries, with processes largely aligned with the ICF and intended to improve measurement and statistics: new national surveys, information systems and ICF-based instruments; and international efforts to improve disability data. Knowledge is growing about the components and interactions of the ICF model, the diverse effects of the environment on functioning, and the meaning and measurement of participation.

CONCLUSION

The ICF provides specificity and a common language in the complex world of functioning and disability and is stimulating new thinking, new applications in measurement and statistics, and the assembling of new knowledge. Nevertheless, the field needs to mature. Identified gaps suggest ways to improve measurement and statistics to underpin policies, services and outcomes. Implications for Rehabilitation The ICF offers a conceptualization of functioning and disability that can underpin assessment and documentation in rehabilitation, with a growing body of experience to draw on for guidance. Experience with the ICF reminds practitioners to consider all the domains of participation, the effect of the environment on participation and the importance of involving clients/patients in assessment and service planning. Understanding the variability of functioning within everyday environments and designing interventions for removing barriers in various environments is a vital part of rehabilitation planning.

The burden of generalized anxiety disorder in Canada

INTRODUCTION

Although generalized anxiety disorder (GAD) is common and disabling, there are few Canadian studies on this mental illness. We compared the characteristics, health status, health services use and health care needs of Canadians with GAD to those with depression.

METHODS

Data are from the 2012 Canadian Community Health Survey-Mental Health, which surveyed a nationally representative sample of Canadians aged 15 years and older (n = 23 709; response rate of 68.9%). The respondents we studied had selfreported symptoms compatible with GAD and/or major depressive episode (MDE) in the preceding 12 months (n = 1598). Estimates were weighted to represent the Canadian household population. We performed descriptive and multinomial multivariate logistic regression analyses.

RESULTS

In 2012, an estimated 700 000 (2.5%) Canadians aged 15 years and older reported symptoms compatible with GAD in the previous 12 months. MDE symptoms co-occurred in 50% of these individuals. Those with GAD only reported fair/poor perceived health (29.7%), moderate to severe psychological distress (81.2%) and moderate to severe disability (28.1%) comparable to (or even slightly worse) than those with MDE only (24.7%, 78.8% and 24.8% respectively). Those with comorbid GAD and MDE demonstrated the worst health outcomes; 47.3% of them reported fair/poor perceived health, 94.0% reported moderate to severe psychological distress and 52.4% reported moderate to severe disability. Nearly 50% of those with comorbid GAD and MDE reported that their need for health care was not met or only partially met, compared to about 30% of those with GAD or MDE only.

CONCLUSION

While GAD is associated with levels of distress and disability comparable to (or slightly worse) than those affected by MDE only, the health status of those with comorbid disease is significantly worse than those with GAD or MDE only. Improved diagnosis, screening for comorbidity and management are essential to minimize the impacts of this mental illness.

Return to work after trauma: A survival analysis

PURPOSE

To evaluate the return to work (RTW) rate, time and predictors among trauma patients using survival analysis.

METHODS

This cohort study was conducted with a three-month follow-up on 300 trauma patients hospitalized in Shahid Beheshti Hospital, Kashan, Iran in 2014. The data were collected through conducting interviews and referring to patients' medical records during their hospital stay and follow-up information at one & three months after discharge from hospital. Final analysis was conducted on the data retrieved from 273 patients. Data were analyzed by chi-square test, Mann-Whitney U test and survival analysis method.

RESULTS

The rate of RTW at the end of the first and the third follow-up months was respectively 21.6% and 61.2%. Survival analysis showed that the RTW time (Time between admission to first return to work) was significantly longer among patients with illiteracy, drug abuse, hospitalization history in the intensive care unit, low socioeconomic status, non-insurance coverage, longer hospital stay, multiple and severe injuries as well as severe disability.

CONCLUSION

Our findings indicated that trauma has profound effects on the rate and time of RTW. Besides disability, many personal and clinical factors can affect the outcome of RTW.

A protective personal factor against disability and dependence in the elderly: an ordinal regression analysis with nine geographically-defined samples from Spain

BACKGROUND

Sense of Coherence (SOC) is defined as a tendency to perceive life experiences as comprehensible, manageable and meaningful. The construct is split in three major domains: Comprehensibility, Manageability, and Meaningfulness. SOC has been associated with successful coping strategies in the face of illness and traumatic events and is a predictor of self-reported and objective health in a variety of contexts. In the present study we aim to evaluate the association of SOC with disability and dependence in Spanish elders.

METHODS

A total of 377 participants aged 75 years or over from nine locations across Spain participated in the study (Mean age: 80.9 years; 65.3% women). SOC levels were considered independent variables in two ordinal logistic models on disability and dependence, respectively. Disability was established with the World health Organization-Disability Assessment Schedule 2.0 (36-item version), while dependence was measured with the Extended Katz Index on personal and instrumental activities of daily living. The models included personal (sex, age, social contacts, availability of an intimate confidant), environmental (municipality size, access to social resources) and health-related covariates (morbidity).

RESULTS

High Meaningfulness was a strong protective factor against both disability (Odds Ratio [OR] = 0.50; 95% Confidence Interval [CI] = 0.29-0.87) and dependence (OR = 0.33; 95% CI = 0.19-0.58) while moderate and high Comprehensibility was protective for disability (OR = 0.40; 95% CI = 0.22-0.70 and OR = 0.39; 95%CI = 0.21-0.74), but not for dependence. Easy access to social and health resources was also highly protective against both disability and dependence.

CONCLUSIONS

Our results are consistent with the view that high levels of SOC are protective against disability and dependence in the elderly. Elderly individuals with limited access to social and health resources and with low SOC may be a group at risk for dependence and disability in Spain.

World Health Organization disability assessment schedule 2.0: An international systematic review

PURPOSE

This systematic review examines research and practical applications of the World Health Organization Disability Assessment Schedule (WHODAS 2.0) as a basis for establishing specific criteria for evaluating relevant international scientific literature. The aims were to establish the extent of international dissemination and use of WHODAS 2.0 and analyze psychometric research on its various translations and adaptations. In particular, we wanted to highlight which psychometric features have been investigated, focusing on the factor structure, reliability, and validity of this instrument.

METHOD

Following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) methodology, we conducted a search for publications focused on "whodas" using the ProQuest, PubMed, and Google Scholar electronic databases.

RESULTS

We identified 810 studies from 94 countries published between 1999 and 2015. WHODAS 2.0 has been translated into 47 languages and dialects and used in 27 areas of research (40% in psychiatry).

CONCLUSIONS

The growing number of studies indicates increasing interest in the WHODAS 2.0 for assessing individual functioning and disability in different settings and individual health conditions. The WHODAS 2.0 shows strong correlations with several other measures of activity limitations; probably due to the fact that it shares the same disability latent variable with them. Implications for Rehabilitation WHODAS 2.0 seems to be a valid, reliable self-report instrument for the assessment of disability. The increasing interest in use of the WHODAS 2.0 extends to rehabilitation and life sciences rather than being limited to psychiatry. WHODAS 2.0 is suitable for assessing health status and disability in a variety of settings and populations. A critical issue for rehabilitation is that a single "minimal clinically important .difference" score for the WHODAS 2.0 has not yet been established.

Variables associated with disability in male and female long-term survivors from acute myocardial infarction. Results from the MONICA/KORA Myocardial Infarction Registry

Increasing attention is paid on functional limitations and disability among people with chronic diseases. However, only few studies have explored disability in persons with acute myocardial infarction (AMI). The objective of this study was to provide a description of disability and to identify determinants of disability in a population-based sample of long-term AMI survivors. The sample consisted of 1943 persons (35-85years) with AMI from the German population-based MONICA/KORA Myocardial Infarction Registry, who responded to a postal follow-up survey in 2011. Disability was assessed with the 12-item version of the World Health Organization Disability Schedule (WHODAS). Multivariate linear regression models were established in order to identify socioeconomic and clinical factors, risk factors and comorbidities which are associated with disability. The mean WHODAS score for the total sample was 7.86±9.38. The regression model includes 26 variables that explained 37.2% of the WHODAS variance. Most of the explained variance could be attributed to the presence of depression, female sex, joint disorders, digestive disorders, and stroke. Depression was the most important determinant of disability in both sexes. Replacement of single comorbidities by the total number of comorbidities resulted in a model with 15 variables explaining 31.9% of the WHODAS variance. Most of the variance was explained by the number of comorbidities. Further significant determinants of disability were female sex, low education level, angina pectoris, and no revascularization therapy. In AMI patients, the number of comorbidities and particularly the presence of depression are important determinants of disability and should be considered in post-AMI health care.

Socio-demographic patterns of disability among older adult populations of low-income and middle-income countries: results from World Health Survey

OBJECTIVE

Our objective was to quantify disability prevalence among older adults of low- and middle-income countries, and measure socio-demographic distribution of disability.

METHODS

World Health Survey data included 53,447 adults aged 50 or older from 43 low- and middle-income countries. Disability was a binary classification, based on a composite score derived from self-reported functional difficulties. Socio-demographic variables included sex, age, marital status, area of residence, education level, and household economic status. A multivariate Poisson regression model with robust variance was used to assess associations between disability and socio-demographic variables.

RESULTS

Overall, 33.3 % (95 % CI 32.2-34.4 %) of older adults reported disability. Disability was 1.5 times more common in females, and was positively associated with increasing age. Divorced/separated/widowed respondents reported higher disability rates in all but one study country, and education and wealth levels were inversely associated with disability rates. Urban residence tended to be advantageous over rural. Country-level datasets showed disparate patterns.

CONCLUSIONS

Effective approaches aimed at disability prevention and improved disability management are warranted, including the inclusion of equity considerations in monitoring and evaluation activities.

Identification of common content between the questionnaire of the Health Survey (ISA-SP) and the International Classification of Functionality, Disability, and Health

The purpose of this paper was to identify the common contents between São Paulo's Health Survey Questionnaire (Physical Disability and Emotional Health Blocks) and the International Classification of Functionality, Disability, and Health. The first stage of the research consisted of the search for the modules of São Paulo's Health Survey, which addressed the issue of disability, and the passages about this theme were highlighted and inserted into a new file. In the second stage, the significant contents were extracted. In the last one, these contents were codified to the codes of the International Classification of Functionality, Disability, and Health by two independent researchers. For the descriptive statistical analysis, crude numbers, percentages, and simple frequencies were used. The degree of agreement between the two professionals was calculated using Kappa's coefficient and the confidence interval. The most common domains were those about functions and body structures and about activities and participation, in which the domain of environmental factors presented a lower frequency of approach.

Funcionalidade de idosos cadastrados em uma unidade da Estratégia Saúde da Família segundo categorias da Classificação Internacional de Funcionalidade

OBJETIVOS: Investigar a funcionalidade de idosos cadastrados na Estratégia Saúde da Família ESF e classificar pelas categorias de Atividade e Participação da Classificação Internacional de Funcionalidade, Incapacidade e Saúde CIF. MÉTODO: Pesquisa transversal, descritiva, realizada em 124 idosos cadastrados na ESF Águas Lindas I, município de Ananindeua, Pará, Brasil. A coleta de dados ocorreu no ambiente domiciliar dos idosos. Investigaram-se as características sociodemográficas, a funcionalidade, pelo Índice de Katz e escala de Lawton, e o nível de Atividade e Participação, segundo a CIF. A análise estatística foi realizada no programa SPSS 18.0, utilizando a média, desvio-padrão e o teste Qui-quadrado de Pearson x2, com descrição da frequência relativa simples de cada domínio avaliado. RESULTADOS: 66,9 % dos idosos eram do sexo feminino, com média de idade 68,5 dp±8,19 anos, casados n=61 e recebiam aposentadoria n=69. Cerca de 65% dos idosos eram independentes para todas as atividades avaliadas pelo Índice de Katz e escala de Lawton. Quanto à classificação da funcionalidade pela CIF, a maioria foi classificada com códigos que indicam nenhuma dificuldade. CONCLUSÃO: A maior parcela dos idosos estudados apresenta-se ativa e participativa, ou seja, é capaz de desempenhar uma tarefa diária, o que talvez represente um envelhecimento com poucas perdas.

Metabolic syndrome and functional ability in older age: the InCHIANTI study

BACKGROUND & AIMS

Metabolic syndrome (MetS) is associated with incident disability in middle-aged subjects. We evaluated the association of MetS with functional ability in an older population.

METHODS

We enrolled 1155 participants aged 65+, derived from the InCHIANTI study, and followed for 3 years. MetS was diagnosed according to the National Cholesterol Education Program's ATP-III criteria. Functional ability was estimated using the Katz's activities of daily living (ADLs), and the Lawton and Brody for the instrumental activities of daily living (IADLs) scales. The association between disability and MetS at baseline and after follow-up was assessed by logistic regression.

RESULTS

At baseline, MetS was associated with reduced probability of ADLs disability among participants aged 74+ (OR = .33, 95% CI = .14-.77; p = .010), but not in younger (5.08, 95% CI = .88-29.24; p = .069). Also, MetS was associated with reduced probability of incident ADLs disability (OR = .61, 95% CI .41-.91; p = .016), but neither with prevalent, nor incident IADLs disability.

CONCLUSIONS

In older persons, MetS is associated with reduced probability of prevalent and incident ADLs disability. Whether older persons with MetS should receive treatment and whether the current diagnostic criteria for MetS apply to older individuals need further investigation.

The International Classification of Functioning, Disability and Health: a systematic review of observational studies

Objective: To systematically review the use of the International Classification of Functioning, Disability and Health (ICF) in observational studies. Methods: This study is a systematic review of articles that use the ICF in observational studies. We took into account the observational design papers available in databases such as PubMed, Lilacs and SciELO, published in English and Portuguese from January 2001 to June 2011. We excluded those in which the samples did not comprise individuals, those about children and adolescents, and qualitative methodology articles. After reading the abstracts of 265 identified articles, 65 met the inclusion criteria. Of these, 18 were excluded. The STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) adapted Checklist, with 15 items needed for observational studies, was applied to the 47 remaining articles. Any paper that met 12 of these criteria was included in this systematic review. Results: 29 articles were reviewed. Regarding the ICF application methodology, the checklist was used in 31% of the articles, the core set in 31% and the ICF categories in 31%. In the remaining 7%, it was not possible to define the applied methodology. In most papers (41%), qualifiers were used in their original format. As far as the area of knowledge is concerned, most of the studies were related to Rheumatology (24%) and Orthopedics (21%). Regarding the study design, 83% of the articles used cross-sectional studies. Conclusion: Results indicate a wide scientific production related to ICF over the past 10 years. Different areas of knowledge are involved in the debate on the improvement of information on morbidity. However, there are only a few quantitative epidemiological studies involving the use of ICF. Future studies are needed to improve data related to functioning and disability.

Disability transitions after 30 months in three community-dwelling diagnostic groups in Spain

Background

Little is known about changes in disability over time among community-dwelling patients. Accordingly, this study sought to assess medium-term disability transitions.

Patients and Methods

300 chronic obstructive pulmonary disease (COPD), chronic heart failure and stroke patients living at home in Madrid were selected from general practitioner lists. In 2009, disability was assessed after a mean of 30 months using the World Health Organisation (WHO) DisabilityAssessment Schedule 2.0 (WHODAS 2.0). Follow-up was completed using death registries. Losses to follow-up were due to: death, 56; institutionalisation, 9; non-location, 18; and non-participation, 17. Changes in WHODAS 2.0 scores and life status were described and analysed using Cox and multinomial regression. Disability at end of follow-up was imputed for 56 deceased and 44 surviving patients.

Results

Mean disability scores for 200 surviving patients at end of follow-up were similar to baseline scores for the whole group, higher than their own baseline scores, and rose by 16.3% when imputed values were added. The strongest Cox predictors of death were: age over 84 years, adjusted hazard ratios with 95%CI 8.18 (3.06-21.85); severe/complete vs. no/mild disability, 5.18 (0.68-39.48); and stroke compared to COPD, 1.40 (0.67-2.91). Non-participants and institutionalised patients had higher proportions with severe/complete baseline disability. A one-point change in baseline WHODAS 2.0 score predicted independent increases in risk of 12% (8%-15%) for severe/complete disability or death.

Conclusions

A considerably high proportion of community-dwelling patients diagnosed with COPD, CHF and stroke undergo medium-term changes in disability or vital status. The main features of the emerging pattern for this group appear to be as follows: approximately two-thirds of patients continue living at home with moderately reduced functional status; 1/3 die or worsen to severe/complete disability; and 1/10 improve. Baseline disability scores, age and diagnosis are associated with disability and death in the medium term.

Analysis of disability using WHODAS 2.0 among the middle-aged and elderly in Cinco Villas, Spain

BACKGROUND

The prevalence of disability, as defined by the International Classification of Functioning, Disability and Health (ICF), among the middle-aged and elderly population is poorly known.

OBJECTIVE

To determine disability prevalence in a resident population sample aged ≥50 years, in the Cinco Villas district, Spain, from June 2008 through June 2009.

METHODS

We used the WHODAS 2.0 36-item questionnaire to quantify the prevalence of disability, globally and by domain, together with a 13-item combined measure of three domains, Getting around, Self-care and Life activities, claimed to reflect the need of integrated services. In addition, we performed exploratory analyses of the relationship between disability and different variables using ordinal logistic regression.

RESULTS

Disability was detected by global WHODAS score in 604 of a total of 1214 persons, i.e., a prevalence of 49.8% 95% CI (46.9-52.5), with the corresponding figures for mild, moderate, severe, and extreme disability being 26.8%, 16.0%, 7.6% and 0.1%, respectively. Disability increased with age, was higher among women, and for specific domains. Prevalence of severe/extreme disability among women vs. men was as follows: Getting around, 26.8% vs. 12.1%; Life activities, 25.2% vs. 6.8%; and Self-care, 9.5% vs. 6.0%. Disability was more frequent among subjects diagnosed with dementia, chronic liver disease, severe mental disease, and stroke. The abovementioned 13-item measure yielded prevalence figures for disability levels quite similar to those obtained using 36-item scores.

CONCLUSIONS

For the first time, this study furnishes detailed disability prevalence figures and data on associated variables in a middle-aged and elderly Western population.

Selection bias in pharmacy-based patient surveys

PURPOSE

To evaluate if there is a selection bias in drug utilization surveys on prescription drugs regularly conducted in Swedish pharmacies, to describe the direction of this potential bias and discuss the implications for the results.

METHODS

Age and gender distributions within patient survey samples from drug utilization surveys conducted during 2006-2010 are compared to the age and gender distribution of all Swedish patients, receiving the same drug or drugs, as given by the Swedish Prescribed Drug Register. The differences between the proportions of patients within the age and gender segments of each pair of survey/register data were calculated.

RESULTS

In 25 (81%) out of 31 included surveys, patients aged 75 years or older are significantly underrepresented, as they are less likely to visit the pharmacy to collect their prescription drugs themselves and thus disqualify for the interviews. Data on women show similar results as overall survey data, whereas the underrepresentation of the oldest age group among men appears in a lower proportion of the surveys, 67%. The general consequence is a selection towards a healthier survey sample, but the consequences in the individual surveys vary, depending on what drug is being studied.

CONCLUSION

Pharmacy-based patient surveys provide a convenient data collection method for patient self-reported data, but patients aged 75 years or older are consistently underrepresented. In surveys where this may influence the main research question, data should also be collected with other methods reaching the oldest patients.

The emerging pattern of disability in Rwanda

PURPOSE

The purpose of this paper is to describe the emerging pattern of disability (activity limitation) in terms of its prevalence, age and gender distribution in Rwanda.

METHOD

A door-to-door survey was conducted in all households in villages from two districts selected through a multi-stage sampling procedure. Identified persons were screened for activity limitations using age-appropriate instruments developed from domains in the ICF. Proportions were computed and disaggregated by age group, gender, district and activity limitation. A multi-disciplinary rehabilitation team including community members participated in the development of instruments, community mobilisation, data collection and collation.

RESULTS

Prevalence rates of 8.6% (Bugesera) and 14.7% (Musanze) were obtained. The prevalence of disability was higher in adults than in children in both districts (10.4% versus 6.6% in Bugesera and 19.6% versus 7.7% in Musanze). Visual limitations occurred the most frequently in both adults and children in both districts. Mobility and mental health limitations also notably contributed to the overall disability burden.

CONCLUSION

The prevalence of disability obtained was higher than all previously reported data for Rwanda. Despite the limitations, the findings provide useful information for planning rehabilitation services and to direct future enquiry into the epidemiology of disability in Rwanda. Implications for Rehabilitation It is important to design specific surveys to measure disability using contemporary methods to gauge the situation accurately and qualitatively. Currently, the ICF provides the best framework to describe the epidemiology of disability meaningfully; it enables comparisons within and between countries and regions of the world; and enables the active participation of a wide range of rehabilitation stakeholders including PWDs and lay community members. The vast majority of disabilities in Rwanda are limitations in visual, mobility and mental health functions.

Prevalence and correlates of disability in a late middle-aged population of women

OBJECTIVE

This study estimates the prevalence of disability among late middle-aged women and identifies important correlates of disability among this population.

METHOD

Disability was assessed among 376 participants of the Michigan Study of Women's Health Across the Nation cohort at the 2011 follow-up using the World Health Organization Disability Assessment Schedule. Demographic and health measures were related to disability status using logistic regression models (none or mild vs. moderate, severe, or extreme disability).

RESULTS

Nearly 25% of women reported moderate to extreme global disability. African American race/ethnicity, economic strain, peripheral neuropathy, and depressive symptomatology were associated with global disability. Obesity, knee osteoarthritis, and hypertension were only associated with disability for the mobility domain (getting around).

DISCUSSION

The prevalence of disability is relatively high among this population of late middle-aged women. Efforts to prevent or forestall disability should be extended to include middle-aged populations as they may be most amenable to intervention.

A funcionalidade dos mais idosos (>75 anos): conceitos, perfis e oportunidades de um grupo heterogêneo

OBJETIVOS: Conhecer a funcionalidade de dois grupos de idosos (75-84 anos e >85 anos) e sua associação com idade e gênero. MÉTODOS: Trata-se de estudo observacional do tipo analítico e transversal, cuja amostra foi constituída por indivíduos de ambos os sexos com idade >75 anos. Foi recolhida informação relativa a condição de saúde e funcionalidade pré-morbilidade. Os instrumentos de coleta de dados foram um questionário de caracterização sociodemográfica e o Método de Avaliação Biopsicossocial. RESULTADOS: A amostra foi constituída por 262 idosos com média de idade de 82,9 ± 4,86 anos, dos quais 161 (61,5%) eram mulheres. Os mais velhos (>85 anos) viviam mais isolados (p=0,020) e tinham menores habilitações literárias (p=0,027), apresentando mais limitações em utilizar escadas (p=0,015), no banho (p=0,008), na continência fecal (p=0,015) e em todas as atividades instrumentais (p<0,031). As mulheres apresentavam maior vulnerabilidade no estado civil (p<0,001) e no status econômico (p=0,009), enquanto os homens tinham piores resultados nas quedas (p=0,003) e nos comportamentos de risco (p<0,001). O desempenho na locomoção e nas atividades básicas e instrumentais era semelhante entre os sexos. CONCLUSÕES: As variáveis de natureza social apresentaram-se diferentes quanto à idade e ao gênero. As componentes da funcionalidade -locomoção, atividades diárias básicas e atividades instrumentais - apresentaram maiores limitações nos idosos com idade > 85 anos, sobretudo as instrumentais. Não se encontraram diferenças na funcionalidade em relação ao gênero.

Distribution and determinants of functioning and disability in aged adults--results from the German KORA-Age study

Background

Today industrialized countries face a burgeoning aged population. Thus, there is increasing attention on the functioning and disabilities of aged adults as potential determinants of autonomy and independent living. However, there are few representative findings on the prevalence and determinants of disability in aged persons in the German population.

The objective of our study is to examine the frequency, distribution and determinants of functioning and disability in aged persons and to assess the contribution of diseases to the prevalence of disability.

Methods

Data originate from the MONICA/KORA study, a population-based epidemiological cohort. Survivors of the original cohorts who were 65 and older were examined by telephone interview in 2009. Disability was assessed with the Health Assessment Questionnaire Disability Index (HAQ-DI). Minimal disability was defined as HAQ-DI > 0. Logistic regression was used to adjust for potential confounders and additive regression to estimate the contribution of diseases to disability prevalence.

Results

We analyzed a total of 4117 persons (51.2% female) with a mean age of 73.6 years (SD = 6.1). Minimal disability was present in 44.7% of all participants. Adjusted for age and diseases, disability was positively associated with female sex, BMI, low income, marital status, physical inactivity and poor nutritional status, but not with smoking and education. Problems with joint functions and eye diseases contributed most to disability prevalence in all age groups.

Conclusions

In conclusion, this study could show that there are vulnerable subgroups of aged adults who should receive increased attention, specifically women, those with low income, those over 80, and persons with joint or eye diseases. Physical activity, obesity and malnutrition were identified as modifiable factors for future targeted interventions.

Long term trend analysis of geographical disparity in aging and disability: Taiwanese population approach

Purposes of the present paper were to describe the overtime change of disability prevalence among the elderly (65 years and older), and to analyze the geographic disparity of the disability prevalence during the year 2000-2010 in Taiwan. Study data mainly come from two public web-access information: (1) The physically and mentally disabled population by age and grade, 2000-2010; (2) Taiwan general population by age, 2000-2010. We used statistical methods include number, percentage and geographical information system (GIS) to describe the disability prevalence among the elderly people by year and administrative area, and a trend test was conducted to examine the overtime change of disability prevalence in the elderly people. The results found that the mean of disability prevalence rate in the elderly population was 14.8% and it was significantly increased during the past 11 years (R(2) = 0.901; p < 0.0001). With regards to the elderly disability prevalence disparity in administrative areas, those areas of higher elderly disability prevalence were more likely to occur in east-mountain areas-Taitung County (24.2%), Yilan County (21.0%), Hualien County (20.3%), and central-agricultural counties such as Yunlin County (21.8%), Nantou County (17.6%) and Chiayi County (17.3%). The most relative change areas of disability prevalence rate in the elderly population during the past 11 years were more likely to occur in central or east areas in Taiwan. The present study highlights the authorities should pay much attention to increasing rate and the geographical disparity of disability prevalence in the elderly population, to allocate appropriate health and welfare resources for this vulnerable population.

Prevalence and features of ICF-disability in Spain as captured by the 2008 National Disability Survey

Background

Since 1986, the study of disability in Spain has been mainly addressed by National Disability Surveys (NDSs). While international attempts to frame NDS designs within the International Classification of Functioning, Disability and Health (ICF) have progressed, in general, the ICF has hardly been used in either the NDS or epidemiological studies. This study sought to identify ICF Activity- and Participation-related content in the most recent Spanish NDS, the 2008 Survey on Disabilities, Independence and Dependency Situations (Encuesta sobre discapacidades, autonomía personal y situaciones de Dependencia - EDAD 2008), and estimate the prevalence of such ICF-framed disability.

Methods

EDAD 2008 methods and questions were perused. Of the 51 EDAD items analysed, 29 were backcoded to specific d2-d7 domains of the ICF Checklist and, by rating the recorded difficulty to perform specific tasks with or without help, these were then taken as performance and capacity respectively. A global ICF score was also derived, albeit lacking data for d1, "Learning and applying knowledge", d8, "Major Life Areas" and d9, "Community, Social and Civic Life". Data were grouped by sex, age, residence and initial positive screening, and prevalence figures were calculated by disability level both for the general population, using the originally designed weights, and for the population that had screened positive to disability. Data for institutionalised persons were processed separately.

Results

Crude prevalence of ICF severe/complete and moderate disability among the community-dwelling population aged ≥6 years was 0.9%-2.2% respectively, and that of severe/complete disability among persons living in sheltered accommodation was 0.3%.

Prevalence of severe/complete disability was: higher in women than in men, 0.8% vs. 0.4%; increased with age; and was particularly high in domains such as "Domestic Life", 3.4%, "Mobility", 1.8%, and "Self-care", 1.9%, in which prevalence decreased when measured by reference to performance. Moreover, global scores indicated that severe/complete disability in these same domains was frequent among the moderately disabled group.

Conclusions

The EDAD 2008 affords an insufficient data set to be ICF-framed when it comes to the Activity and Participation domains. Notwithstanding their unknown validity, ratings for available ICF domains may, however, be suitable for consideration under the ADL model of functional dependency, suggesting that there are approximately 500,000 persons suffering from severe/complete disability and 1,000,000 suffering from moderate disability, with half the latter being severely disabled in domains capable of benefiting from technical or personal aid. Application of EDAD data to the planning of services for regions and other subpopulations means that need for personal help must be assessed, unmet needs ascertained, and knowledge of social participation and support, particularly for the mentally ill, improved. International, WHO-supported co-operation in ICF planning and use of NDSs in Spain and other countries is needed.

Medical, environmental and personal factors of disability in the elderly in Spain: a screening survey based on the International Classification of Functioning

OBJECTIVES

The International Classification of Functioning, Disability and Health (ICF) advocates a multifactorial and multifaceted conceptualization of disability. The objective of this study was to ascertain major medical, environmental and personal determinants of severe/extreme disability among the elderly population in Spain. The assessment scheme was consistent with the ICF model of disability.

METHODS

Nine populations contributed probabilistic or geographically-defined samples following a two-phase screening design. The Mini-Mental State Examination and the 12-item version of the World Health Organization-Disability Assessment Schedule, 2(nd) ed. (WHO-DAS II), were used as cognitive and disability screening tools, respectively. Positively screened individuals underwent clinical work-up for dementia and were administered the 36-item version of the WHO-DAS II to estimate ICF disability levels. We used logistic regression for the purposes of data combination, adjusted for age and sex in all analyses.

RESULTS

The sample was composed of 503 participants aged ≥ 75 years. Alzheimeŕs disease and depression were highly predictive of severe/extreme disability (OR: 17.40, 3.71). Good access to social services was strongly associated with a low level or absence of disability (OR: 0.05 to 0.18). Very difficult access to services and having dementia or another psychiatric disorder were associated with an increase in disability (OR: 66.06). There was also a significant interaction effect between access to services and neurological disorders (OR: 12.74).

CONCLUSIONS

Disability is highly prevalent among the Spanish elderly and is influenced by medical, social and personal factors. Disability could potentially be reduced by ensuring access to social services, preventing dementia and stroke, and treating depression.
