Could an increased risk of obstructive sleep apnoea be one of the determinants associated with disability in individuals with cardiovascular and cerebrovascular diseases?

PURPOSE: To investigate a possible association between the risk of obstructive sleep apnoea (OSA) and disability in individuals with cardiovascular or cerebrovascular diseases. METHODS: Cross-sectional study was conducted with 373 individuals (313 with cardiovascular or cerebrovascular diseases and 60 healthy). Disability was assessed by the 12-item World Health Organization Disability Assessment Schedule (WHODAS), and the risk of OSA was assessed by STOP-BANG. Anxiety and depression symptoms, daytime sleepiness, and cognition were assessed by the Hospital Anxiety and Depression Scale (HADS), Epworth Sleepiness Scale (ESS), and Mini Mental State Examination (MMSE). RESULTS: Greater disability was found in individuals with intermediate or high risk of OSA, considering healthy individuals (p=0.03), or individuals diagnosed with arrhythmia (p<0.01) or coronary artery disease (p=0.04). A high risk of OSA and higher WHODAS scores was significant among women as well as between OSA risk categories (p<0.01). Cognitive deficit and level of education also showed differences between OSA risk categories. Age, depression, and sleepiness were also associated with the subjects' disability (p<0.01). Gamma regression model showed higher WHODAS scores in female, in those with intermediate and high risk of OSA, and in those with depressive symptoms and cognitive deficit. Age also showed a correlation with higher WHODAS scores. The presence of all investigated cardio and cerebrovascular diseases showed an increase in the WHODAS score, implying a greater disability compared to healthy individuals. CONCLUSION: Moderate and high risk of OSA is associated with disability, as well as gender, age, depressive symptoms, cognitive deficit, and cardiovascular diseases.

Predictive Factors for the Risk of Sexual Dysfunction in Climacteric Women: Population-based Study.

BACKGROUND: It is known that sexual problems increase with age but little is known about the predictors of female sexual dysfunction (FSD) in Brazilian climacteric women. AIM: To identify predictive factors for FSD in climacteric women. METHODS: This is a cross-sectional population-based study carried out through a household survey. OUTCOMES: The measures investigated were sociodemographic characteristics, depressive symptoms, level of physical activity, presence of FSD, self-rated health and sleep satisfaction. RESULT: A total of 381 climacteric, sexually active women were included, with a mean age of 55.04 (±7.21) years. The prevalence of FSD was 38.3%. All variables investigated were associated with FSD (P < .05). In the final model, the predictors for FSD were low satisfaction with sleep (OR 4.20; 95% CI 2.32-7.62), advanced age (OR 1.04; 95% CI 1.00-1.08), low education level (OR 0.90; 95% CI 0.85-0.97) and having a partner (OR 0.35; 95% CI 0.16-0.76). CLINICAL IMPLICATION: These aspects deserve attention from the health team to prevent and identify FSD early in life in climacteric women. STRENGTHS & LIMITATIONS: This study support existing data about risk factors for FSD in climacteric women. However, it is not possible to attribute causality to any of the correlates identified, which is a limitation of cross-sectional studies. CONCLUSION: Dissatisfaction with sleep, senility, insufficient income, low education, not having a partner, complaints of depression, and the worse perception of global health are predictive factors for FSD in climacteric women.

Are the International Classification of Functioning, Disability and Health (ICF) domains considered in the obstructive sleep apnea instruments? An integrative review.

PURPOSE: Obstructive Sleep Apnea (OSA) is related to cardiovascular, metabolic, and neurocognitive diseases. Furthermore, OSA symptoms, such as excessive sleepiness, fatigue, and mood disorders, may interfere in functioning. The assessment of this aspect in patients with OSA is not frequent and no specific instrument is available in the literature. Our aim is to identify if the International Classification of Functioning, Disability and Health (ICF) domains are considered in the validated instruments used to assess patients with OSA. METHODS: In this integrative literature review, three databases were searched: Pubmed, Embase, and LILACS. Bibliographic survey was carried out in 2020, between March and July. Articles published in English, Portuguese, and Spanish with validated tools to assess OSA in adults were included. RESULTS: Thirty instruments have undergone a process of concept extraction and coding according to the ICF, generating a total of 769 significant concepts. It was observed that the function domain was the most prevalent, making 42% (n = 323) of the concepts, followed by domains of activity (16%), participation (10%), environmental factors (5%), personal factor (5%), and structure (1%). Only one instrument, the "Sleep Apnea Quality of Life Index (SAQLI)," encompasses all domains of the ICF in its constructs. CONCLUSION: In the analyzed instruments, the function domain prevails, with most concepts related to sleep functions. Only one validated instrument included in this research covered all the ICF domains. This instrument closely matched the recommended way of assessing functioning, though it approached the domains in an unbalanced way.

Which Components of The International Classification of Functioning, Disability and Health (ICF) are Covered by Cardiac Rehabilitation Assessment Tools among Individuals with Heart Failure?

BACKGROUND: The therapeutic assessment of functioning in cardiac rehabilitation from the perspective of the International Classification of Functioning, Disability and Health (ICF) can provide a biopsychosocial approach to health care. However, it is unclear which components are reflected in the instruments used for cardiac rehabilitation in individuals with heart failure (HF). OBJECTIVES: To investigate which ICF components (body function, structures, activities, participation, environmental factors, and personal factors) are represented in the assessment instruments used in individuals with HF and to identify the most appropriate instrument to use based on the inclusion of these factors. METHODS: Forty-four clinical trials included in an updated Cochrane systematic review that investigated the effects of exercise-based cardiac rehabilitation in patients with HF were reviewed. The instruments were analyzed to extract significant concepts linked to the ICF codes. RESULTS: A total of 12 outcomes and 40 instruments were identified. The concepts were linked to 2466 codes in the following ICF components: body functions (41.8%), activities (29.7%), participation (8.4%), environmental factors (3.8%), personal factors (1.3%), and body structures (1.0%); other concepts (13.9%) were classified as not covered by ICF. None of the instruments presented concepts linked to all ICF components. The Minnesota Living with Heart Failure Questionnaire (MLHFQ), however, demonstrated comprehensive coverage of the ICF components, with the exception of body structure. CONCLUSIONS: Body function was the most frequently detected ICF component. Individual instruments did not provide a comprehensive perspective on the functioning level of individuals with HF. The MLHFQ provided the greatest coverage of ICF components.

The Brazilian version of the World Health Organization Disability Assessment Schedule (WHODAS 2.0) is reliable and valid for chronic stroke survivors.

BACKGROUND: Stroke is the leading cause of disability worldwide. Assessing stroke's impact on patients' daily activities and social participation can provide important complementary information to their rehabilitation process. However, no previous study had been conducted on the psychometric properties of the Brazilian version of the WHO Disability Assessment Schedule 2.0 (WHODAS 2.0) in the stroke population. OBJECTIVES: This study aimed to examine the internal consistency, test-retest and inter-rater reliability, convergent validity and floor/ceiling effect of the Brazilian version of the WHODAS 2.0 in individuals after chronic stroke. METHODS: Two examiners interviewed 53 chronic stroke individuals who responded to the Brazilian 36-item version of the WHODAS 2.0 three times to analyze test-retest and inter-rater reliabilities. Floor/ceiling effects were calculated as relative frequencies of the lowest or the highest possible WHODAS 2.0 scores. Participants also responded to the Stroke Impact Scale 3.0 (SIS 3.0) and the Functional Independence Measure (FIM) to analyze convergent validity. RESULTS: The internal consistency analyses for domains of WHODAS showed a strong correlation among the items of each domain (0.76-0.91) except for the "getting along" domain, which presented a moderate correlation (ρ = 0,62). Total scores of WHODAS 2.0 showed satisfactory internal consistency (α = 0.93), good inter-rater reliability (ICC = 0.85), excellent test-retest reliability (ICC = 0.92) and no significant floor/ceiling effect. Convergent validity indicated moderate to strong correlations (ρ=-0.51 to ρ=-0.88; p < 0.001), with the highest values associated with the correlation with the SIS scale. CONCLUSIONS: The Brazilian version of the WHODAS 2.0 instrument presented evidence of reliability and validity for chronic post-stroke individuals.

Multimorbidity patterns and associated factors in a megacity: a cross-sectional study.

OBJECTIVE: To identify empirical patterns of multimorbidity and quantify their associations with socioeconomic, behavioral characteristics, and health outcomes in the megacity of São Paulo. METHODS: This was a cross-sectional study conducted through household interviews with residents aged 20 years or older in urban areas (n = 3,184). Latent class analysis was used to identify patterns among the co-existence of 22 health conditions. Age-adjusted prevalence ratios were estimated using Poisson regression. RESULTS: The analysis of latent classes showed 4 patterns of multimorbidity, whereas 58.6% of individuals were classified in the low disease probability group, followed by participants presenting cardiovascular conditions (15.9%), respiratory conditions (12.8%), and rheumatic, musculoskeletal, and emotional conditions (12.8%). Older individuals, with lower schooling and lower household income, presented higher multimorbidity prevalence in cardiovascular, respiratory, rheumatic, musculoskeletal, and emotional conditions patterns compared with the low disease probability pattern. CONCLUSION: The results showed four distinct patterns of multimorbidity in the megacity population, and these patterns are clinically recognizable and theoretically plausible. The identification of trends between patterns would make it feasible to estimate the magnitude of the challenge for the organization of health care policies.

Impairments and related social inequalities among adults: a population-based study in São Paulo city, Brazil.

The study of the association of social variables with the prevalence of impairments can provide subsidies for more adequate care and health policies for the most needy people by incorporating social aspects. This article aims to estimate the prevalence of diverse types of impairments, the degree of difficulty, limitations, and the need for help they cause and attest whether this prevalence differ by educational attainment in individuals aged 20 years or older. This is a populational cross-sectional study (2015 Health Survey of São Paulo-ISA Capital). Data from 3184 individuals were analyzed via educational attainment as exposure variable and outcome variables related to visual, hearing, intellectual, and mobility impairments. 19.9% of participants had visual, 7.8%, hearing, 2.7%, intellectual, and 7.4%, mobility impairments. Mobility and intellectual impairments limited participants' daily activities the most, 70.3% and 63.3%, respectively; who, thus, needed the most help: 48.9% and 48.5%, respectively. Lower schooling was associated with a higher prevalence of impairments, greater need for help due to visual and intellectual impairments, and greater limitations due to hearing and visual impairments.

[Multimorbidity and utilization of health services in the city of São Paulo, Brazil: prevalence and associated factors]. / Multimorbidade e utilização de serviços de saúde no município de São Paulo, Brasil: prevalência e fatores associados.

The scope of this paper was to estimate the prevalence of multimorbidity in the city of São Paulo and to verify the factors associated with the utilization of the health services. It involved a population based cross-sectional study based on data from the Health Survey in the city of São Paulo, in which descriptive analysis was conducted, and logistic regression models were developed using multimorbidity and sociodemographic independent variables, living conditions and use of health services as the outcome. A total of 3,184 individuals aged 20 years or older participated, with a mean age of 43.8 years. The prevalence of multimorbidity was 50.7% among women, 62.5% among those who reported some health problem and 55.1% among those who had recourse to health services in the last 2 weeks. A higher prevalence was identified among those who used the health service due to a mental health problem (66.1%), and in those who reported higher health expenditures in the preceding month (55.4%). Multimorbidity was more frequently associated with aging, in the population with a higher economic status, with worse self-rated health, who frequented health services for 6 months or less, who reported a health problem, or who had a health plan and opted for polypharmacy.

O objetivo foi estimar a prevalência de multimorbidade no município de São Paulo e verificar os fatores associados à utilização de serviços de saúde. Estudo transversal de base populacional a partir do Inquérito de Saúde do Município de São Paulo (ISA-Capital 2015), em que foi realizada análise descritiva e foram elaborados modelos de regressão logística utilizando como desfecho a multimorbidade e variáveis independentes sociodemográficas, de condições de vida e utilização de serviços de saúde. Participaram 3.184 indivíduos com 20 anos ou mais, idade média de 43,8 anos. A prevalência de multimorbidade foi de 50,7% entre as mulheres, 62,5% entre os que relataram algum problema de saúde e 55,1% entre os que utilizaram serviços de saúde nas duas últimas semanas. Foi identificada maior prevalência nos indivíduos que usaram serviço de saúde por problema de saúde mental (66,1%) e que informaram maiores despesas com saúde no último mês (55,4%). A multimorbidade foi mais frequente com o envelhecimento, na população com nível econômico mais elevado, com pior autoavaliação de saúde, que utilizou serviços de saúde há seis meses ou menos, que relatou problema de saúde, que tinha plano de saúde e fazia uso da polifarmácia.

Validation of tele-assessment of disability and health after stroke using WHODAS 2.0 through video call in a middle-income country.

BACKGROUND: The validity, reliability, and accuracy of the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) for face-to-face assessment in the stroke population are well established. However, the validity and reliability of WHODAS 2.0 through tele-assessment remain uncertain. OBJECTIVE: To assess the reliability, agreement, internal consistency, criterion and discriminant validity of WHODAS 2.0 when administered through video calls. METHODS: A longitudinal methodological study included fifty individuals with chronic stroke. Both in-person and video call assessments were conducted, and their sequence was randomized. The reliability was determined using the Intraclass Correlation Coefficient (ICC2,1). Measurement errors were assessed using the standard error of measurement (SEM) and smallest detectable change (SDC). Internal consistency was assessed using Cronbach's α. Criterion validity was determined by conducting Pearson's correlation coefficient analysis between in-person and video call assessments. Discriminant validity was examined using the Receiver Operating Characteristic (ROC) curve to distinguish disability levels, with the Modified Rankin Scale as the reference standard. RESULTS: The participants had a mean age of 56.10 ± 10.8 years, with an equal distribution of genders. Adequate reliability was observed between the two methods (ICC2,1 = 0.88; 95% CI = 0.79-0.93; p < 0.001), and internal consistency was also adequate (Cronbach's α = 0.88). The criterion validity revealed a strong correlation (r = 0.78; p < 0.001). Discriminant validity demonstrated satisfactory accuracy in distinguishing disability levels via video call (AUC = 0.67; p = 0.04). DISCUSSION: This study offers evidence supporting the validity and reliability of the WHODAS 2.0 assessment through video call. Teleassessment using WHODAS 2.0 proves suitable for individuals who have had a stroke, enabling remote evaluation and care.

Standardization use of the international classification of functioning, disability and health in the determination of health status in patients with post-acute COVID-19 syndrome.

PURPOSE: To propose a standardized method for the use of the International Classification of Functioning, Disability and Health (ICF) to describe the health status in Post-Acute COVID-19 Syndrome (PACS) and investigate interrater agreement in the linking process in instruments and clinical exams using the ICF categories. MATERIALS AND METHODS: Cross-sectional and interrater agreement study that followed the Guidelines for Reporting Reliability and Agreement Studies. Two raters performed the linking coding process in instruments of quality of life, anxiety and depression, fatigue and pulmonary function, inspiratory muscle strength and cardiopulmonary exercise testing. The codes were qualified by standards defined to each instrument and exams. RESULTS: The instrument with the lowest Cohen's Kappa coefficient was anxiety and depression (k = 0.57). Forty ICF codes were linked to clinical instruments and exams. The fatigue instrument presented a higher degree of disability by the qualification process, from severe to complete, in the linked codes. CONCLUSION: The study presents a standardized method for the assessment of the health status of patients with PACS through ICF. Restriction in work performance, socialization and family relationships as well as disabilities in physical endurance, fatigue and exercise tolerance were found in the sample. The agreement between the raters was moderate to perfect, demonstrating that the method can be reproducible.

The body structures and functions, environmental factors, activities and participation in a person's environment are determinant aspects of his health.Ways to measure these aspects are key to assessing health not only as absence of disease, so the International Classification of Disability and Functional Health demonstrates the ability to fully describe health.This study proposes a standardization in the use of the tool to facilitate usability in clinical practice.

Reliability and validity of the Brazilian version of the world health organization disability assessment schedule (WHODAS 2.0) questionnaire for women with urinary incontinence.

PURPOSE: To analyze the reliability and validity of the WHODAS 2.0 instrument for women with urinary incontinence (UI). METHODS: This is a methodological study with Brazilian women with complaints of urge, stress or mixed UI, over 18 years old, without cognitive disorders. The WHODAS 2.0 (36-item version) and the auxiliary instruments were applied through face-to-face and telephone interviews after 7-14 d. The psychometric properties evaluated were: Cronbach's alpha for internal consistency, intraclass correlation coefficient (ICC) for intra-rater test-retest, Spearman's correlation coefficient (rho) for construct validity of WHODAS 2.0 with auxiliary instruments; and ANOVA for discriminative validity with UI severity. RESULTS: 101 women with UI with a mean age of 50.71 ± 10.39 were included. WHODAS 2.0 showed good reliability in all domains and excellent reliability in the total score (>0.80). The intra-evaluator test-retest showed ICC values between 0.59 and 0.87 (p < 0.001). We observed a positive correlation between the WHODAS 2.0 domains and the instruments recommended by International Continence Society (ICS), with greater emphasis on moderate correlation with the Urinary Impact Questionnaire (IUQ-7) subscale (rho = 0.730 p < 0.001). CONCLUSION: The WHODAS 2.0 instrument is a reliable and valid questionnaire for investigating the functioning and disability of women with UI.

The WHODAS 2.0 is a valid and reliable tool for future functioning research with women with urinary incontinence.The WHODAS 2.0 can be used in clinical practice to assess disabilities in women with urinary incontinence.The validation of WHODAS 2.0 reinforces the need for rehabilitation based on the functioning needs of each patient with urinary incontinence.The WHODAS 2.0 assesses functioning based on the biopsychosocial model, supported by the ICF (International Classification of Functioning, Disability and Health).

Promoting diversity and overcoming publication barriers in Latin American neuroscience and Alzheimer's disease research: A call to action.

Alzheimer's disease (AD) is a global health issue. Because AD is a condition demanding effective management, its socioeconomic burden is immense and threatens the health systems of both low- and middle-income (LMIC) and high-income (HIC) countries. However, while most of the HICs are increasing their budget for AD research, the situation is different in LMICs, and resources are scarce. In addition, LMIC researchers face significant barriers to publishing in international peer reviewed journals, including funding constraints; language barriers; and in many cases, high article processing charges. In this perspective, we discuss these disparities and propose some actions that could help promote diversity, and ultimately translate into improved AD research capacity in LMICs, especially in Latin American and Caribbean countries. HIGHLIGHTS: Researchers in low- and middle-income countries (LMIC) face increasing difficulties such as financial constraints, language barriers, and article processing charges.Publication fees, in particular, can be a significant barrier in the process of publication and equal access to scientific information.Publication fee equalization initiatives by publishing companies could reduce the scientific inequality that disadvantages researchers in LMICs.

Questionnaires that assess disability in children and adolescents with low back pain adhere to the concepts of the International classification of functioning, disability and health (ICF), but lack validity for this population: a systematic review.

PURPOSE: We aimed to identify Patient-Reported Outcome Measures (PROMs) that assess disability in children and adolescents with low back pain (LBP), analyzing their adherence to the International Classification of Functioning, Disability and Health (ICF) biopsychosocial model; and to describe the measurement properties of these PROMs. METHODS: We searched Pubmed, Embase and CINAHL databases. The review included searches up to March 2022. Meaningful concepts of the PROMs were linked to ICF domains, and we manually searched for the measurement properties of each included PROM. RESULTS: We included 23 studies, of which eight PROMs were analyzed. We retrieved 182 concepts in total. Activities was the domain with the highest number of linked concepts, whereas personal factors had no linked concepts. The modified Hannover Functional Ability Questionnaire (mHFAQ) and the Micheli Functional Scale (MFS) had measurement properties tested in children and adolescents, but had no information about construct validity. CONCLUSION: Although most of the identified PROMs had broad coverage of their concepts in the ICF, only two PROMs had measurement properties tested in the population of interest in this review, in which the mHFAQ presented wide coverage in relation to the ICF. Further studies are needed to investigate content validity of these PROMs.

This review adds evidence to the area of musculoskeletal disorders in children and adolescents, which is still underexplored.Valid adult Patient-Reported Outcome Measures (PROMs) have been used to assess disability in children and adolescents with low back pain. However, it is recommended to use PROMs that are tested and valid for evaluation of the population of interest.The activities domain was the International Classification of Functioning, Disability and Health domain that presented the highest number of linked concepts, whereas concepts from personal factors were absent.The modified Hannover Functional Ability Questionnaire and the Micheli Functional Scale could potentially be used to assess disability in children and adolescents with low back pain, but high-quality studies are needed for the measurement properties, in particular content validity and responsiveness.

Biopsychosocial Model Domains in Clinical Practice Guidelines for Return to Sport After ACL Injury: Systematic Review Using the AGREE II Checklist.

CONTEXT: The current status of return-to-sport (RTS) criteria can be understood from the International Classification of Functioning, Disability, and Health (ICF), which emphasizes an individual-centered approach and inclusion of all domains of human functioning, and ensures the multifactorial and biopsychosocial nature of decision-making. OBJECTIVE: To analyze the inclusion of biopsychosocial model domains in clinical practice guidelines (CPGs) for RTS after anterior cruciate ligament (ACL) injury, as well as the quality of these CPGs. STUDY DESIGN: Systematic review of CPGs. LEVEL OF EVIDENCE: Level 1. SEARCH STRATEGY: Two independent reviewers developed the search strategy, and a third reviewer corrected and compiled the developed strategies used. DATA SOURCES: Ovid/Medline, Embase, and PEDro without restriction dates. STUDY SELECTION: CPGs for RTS after ACL injury at any age or sport level, and published in English. DATA EXTRACTION: Two independent reviewers codified the RTS criteria recommended in the CPGs according to the ICF domains, and the Appraisal of Guidelines for Research and Evaluation II (AGREE II Checklist) was used for critical appraisal. RESULTS: A total of 715 records were identified, and 7 CPGs were included. Frequency distribution of the biopsychosocial model domains was as follows: body functions (37.77%), activity and participation (20.00%), body structure (13.33%), environmental factors (11.11%), and personal factors (8.88%). In the AGREE II Checklist, the lowest mean domain scores were for rigor of development (37.86 ± 36.35) and applicability (49.29 ± 22.30), and 71.42% were of low or moderate quality. CONCLUSION: The CPGs cannot address the biopsychosocial model domains satisfactorily and some do not address all the ICF conceptual model components, emphasizing body functions and activity and participation domains. Therefore, the functioning model advocated by the World Health Organization has not yet been adequately incorporated into the recommendations for RTS after ACL injury. Moreover, most CPGs are of limited quality.

Translation and cross-cultural adaptation of the Model Disability Survey (MDS) for Brazil.

OBJECTIVE: This study has as objective the translation and cross-cultural adaptation of the Model Disability Survey (MDS), a World Health Organization instrument that provides comprehensive information on disability/functioning, for Brazil. METHODS: This is a cross-sectional methodological study, carried out through five stages - initial translation, synthesis of translations, reverse translation, review by a specialist committee, and pre-test -, considering properties such as semantic, idiomatic, experimental, and conceptual equivalence. Translators, researchers, a mediating team, health professionals, a methodologist and a language specialist were needed to pass through the stages. Statistical analysis was produced from absolute and relative frequencies, measures of central tendency and dispersion, normality tests and content validity index (CVI) > 0.80. RESULTS: The MDS has 474 items, which generated 1,896 analyzes of equivalence. Of these, 160 items had a CVI < 0.80 in at least one of the four types of equivalence and required adjustments. After adaptations and approval by the judges, the pre-final version went on to the pre-test with 30 participants from four regions of the Brazilian Northeast. Regarding this sample, 83.3% are women, single, with an average age of 33.7 years (SD 18.8), self-declared as black or brown, active workers, with technical education and living with three residents. Interviews lasted 123 minutes on average, where 127 health conditions were mentioned, and the most frequent cited were anxiety and back pain. Answers were analyzed and 63 items were cited as needing some adjustment, two of which were submitted for analysis by the committee because they presented a CVI < 0.80. The instrument, guide and presentation cards were adjusted after a new pre-test. CONCLUSIONS: The MDS was translated and cross-culturally adapted to Brazilian Portuguese and showed adequate content validity.

Impairments, health conditions and health risk behaviors: occurrence and associations, in the National Health Survey, Brazil, 2019.

OBJECTIVE: To analyze association of visual, hearing, mental/intellectual, physical and multiple impairments with health conditions and health risk behaviors in Brazil. METHODS: This was a cross-sectional study, using data from the 2019 National Health Survey; associations between impairments and presence of cardiovascular disease (CVD), hypertension, diabetes mellitus (DM), high cholesterol, alcohol abuse and smoking were estimated using logistic regression, thus obtaining the odds ratios (OR). RESULTS: Impairment was reported by 7.6% of the 90,846 participants. Having a impairment was associated with greater odds of reporting chronic conditions, especially CVD (OR = 2.11; 95%CI 1.76;2.54) and DM (OR = 1.78; 95%CI 1.56;2.02 ); visual impairment was associated with greater odds of smoking (OR = 1.52; 95%CI 1.28;1.81); mental/intellectual impairment was inversely related to smoking (OR = 0.45; 95%CI 0.30;0.67) and alcohol abuse (OR = 0.13; 95%CI 0.06;0.26). CONCLUSION: Having any of the impairments studied may be associated with greater odds of having chronic health conditions. MAIN RESULTS: Positive association was identified between having one or more impairments, and health conditions and health risk behaviors. The higher the prevalence of mental/intellectual, physical and multiple impairments, the lower alcohol abuse and smoking. IMPLICATIONS FOR SERVICES: As this population is vulnerable to chronic health conditions, health services need strategies to reduce barriers to access, as well as health promotion actions, such as health education, adapted for people with impairments. PERSPECTIVES: Topics for future studies, examining the inverse relationship between impairments and alcohol abuse and smoking, in addition to acting on the causal chain, so as to prevent health conditions and health risk behaviors.

Is it time to rethink disability assessment in low back pain? Reliability, internal consistency, and construct validity of the Brazilian WHODAS 2.0 for chronic low back pain.

BACKGROUND AND PURPOSE: The World Health Disability Assessment Schedule 2.0 (WHODAS 2.0) was developed to assess health and disability based on the biopsychosocial model. The WHODAS 2.0 has not been validated for Brazilians with chronic non-specific low back pain (LBP). We aimed to evaluate the reliability, internal consistency, and construct validity of the Brazilian version of the WHODAS 2.0 in patients with chronic LBP. METHODS: Methodological study. The Brazilian version of the WHODAS 2.0 was applied to 100 volunteers with chronic nonspecific LBP. Test-retest reliability, internal consistency, and construct validity were assessed using the Spearman correlation test, Cronbach's alpha (α) coefficient, and Spearman's correlation test between WHODAS 2.0, the Oswestry Disability Index (ODI), Roland-Morris Disability Questionnaire (RMDQ), and Fear Avoidance Beliefs Questionnaire (FABQ), respectively. RESULTS: WHODAS 2.0 showed satisfactory test-retest reliability with a moderate correlation for total WHODAS 2.0 (r = 0.75, p < 0.05). Internal consistency was adequate for all domains and total score (α = 0.82-0.96). Regarding construct validity, WHODAS 2.0, ODI (r = 0.70, p < 0.05), and WHODAS 2.0 and RMDQ (r = 0.71, p < 0.05) had significant correlations. Total WHODAS 2.0 and FABQ-Phys subscale scores correlated moderately (r = 0.66, p < 0.05). DISCUSSION: The Brazilian WHODAS 2.0 was proved to be a valid and reliable tool for patients with chronic LBP. The item referring to sexual intercourse had 27% and 30% of the missing values during the test and retest stage, respectively and had a high percentage of missing data for work-related questions (41% missing data) in the life activities domain; therefore, the data must be interpreted with caution. IMPLICATIONS FOR PHYSIOTHERAPY PRACTICE: WHODAS 2.0 can be used as a disability assessment strategy from a biopsychosocial perspective in this population.

Relationship between personal and environmental factors and prevalence of acquired physical impairment in Brazil - a population-based study. / Relação de fatores pessoais e ambientais com a prevalência de deficiências físicas adquiridas no Brasil - estudo de base populacional.

The aim of this study was to estimate the relationship between personal and environmental factors and the prevalence of acquired physical impairment in adults and older persons in Brazil. We conducted a cross-sectional study using data from the 2013 National Health Survey. The response variable was self-reported acquired physical impairment. The explanatory variables were sex, race/skin color, education level, social class, paid employment, private health insurance, running water, and connection to a sewer network. The strength of association between the explanatory variables and response variable and respective 95% confidence intervals were estimated using Poisson Regression. Physical impairment was reported by 1.25% of the study population (n=55,369). After complete adjustment, being male and non-white, having a lower level of education, living alone, not being in paid employment, not having private health insurance, not having running water, and not living in a house connected to a sewer network were associated with higher prevalence of acquired physical impairment. The findings show that prevalence of physical impairment was higher among vulnerable groups and that personal and environmental factors are important elements that need to be assessed at the population level.

Objetivou estimar a relação de fatores pessoais e ambientais com a prevalência de deficiência física adquirida em adultos e idosos brasileiros. Realizado um estudo transversal com dados da Pesquisa Nacional de Saúde (PNS) 2013. A variável resposta foi: autorrelato deficiência física adquirida. As variáveis explicativas de interesse foram: sexo, raça/cor, escolaridade, classe social, trabalho remunerado, plano de saúde, água canalizada e rede de esgoto. As magnitudes das associações e seus respectivos intervalos de confiança (95%) foram estimadas utilizando a Regressão de Poisson. O autorrelato de deficiência física foi encontrado em 1,25% dos 55.369 participantes. Após completo ajustamento, o sexo masculino, raça/cor não branca, menores níveis de escolaridade, viver sozinho, não ter trabalho remunerado, plano de saúde, água canalizada e rede de esgoto foram associados a maiores prevalências de deficiência física adquirida. Esses achados evidenciam que a população mais vulnerável apresenta maior prevalência de deficiência física e os fatores pessoais e ambientais são importantes de serem avaliados em nível populacional.
