El índice de masa corporal como fenotipo en el perfil clínico y funcional en mujeres con osteoartritis de rodilla / Association between the functional impact of osteoarthritis and body mass index in women

Background: Obesity is associated with pain, reduction of function and quality of life in patients with osteoarthritis (OA). Aim: To describe the clinical profile of women with knee OA according to their body mass index (BMI). Material and Methods: Observational study in 308 women with knee OA. According to their BMI, they were classified as normal-weight, overweight and obese. The primary outcome measure was functionality evaluated with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Secondary outcomes were sleep quality evaluated using the Pittsburgh Sleep Quality Index (PSQI) and quality of life assessed with the European Quality of Life Five Dimension (EuroQol-5D). Results: WOMAC, PSQI and EuroQol-5D scores were significantly higher in obese women. Conclusions: Overweight and obese women with OA have more sleep disorders, reduction on functionality and quality of life compared to their normal weight counterparts.

Comparative study of functional capacity and quality of life among obese and non-obese elderly people with knee osteoarthritis / Estudo comparativo da capacidade funcional e qualidade de vida entre idosos com osteoartrite de joelho obesos e não obesos

ABSTRACT Introduction: The association between osteoarthritis (OA) and obesity can lead to a reduced functional capacity, compromising the quality of life (QoL) of the elderly. Objective: To compare the functional capacity and QoL of obese and non-obese older adults with knee OA. Methods: The sample consisted of 35 subjects with OA divided into two groups, obese and non-obese subjects, according to their body mass index. To assess functional capacity, performance tests such as Timed Up and Go (TUG), gait speed test, and the six-minute walk test (6 MWT) were carried out. To assess QoL, WOMAC and SF-36 questionnaires were administered. We performed descriptive and inferential statistics using SPSS software version 20.0. Results: Elderly patients with OA were divided into two groups (obese, n = 16; non-obese, n = 19). Socio-demographic characteristics were similar between groups (p > 0.05). The obese group showed a worst performance in TUG, brisk walking speed and 6 MWT. A more severe pain was found in the following items: “performing heavy housework chores”, “going down stairs”, “bending to floor” and “getting up from bed” in the obese group (p < 0.05). In addition, the obese group had more difficulty to perform tasks for the following items: “going down stairs”, “rising from a chair”, “standing” and “getting on/off toilet” (p < 0.05). There was no statistically significant difference in the assessed domains of SF-36 between groups (p > 0.05). Conclusion: OA associated with obesity caused a negative impact on functional capacity; however, quality of life scores were low, and no difference in obese and non-obese subjects was found.

RESUMO Introdução: A associação entre osteoartrite (OA) e obesidade pode gerar redução da capacidade funcional e comprometer a qualidade de vida (QV) de idosos.Objetivo Comparar a capacidade funcional e a QV entre idosos com OA no joelho, obesos e não obesos.A amostra foi constituída por 35 idosos com OA divididos em dois grupos, obesos e não obesos, de acordo com o índice de massa corporal. Para avaliação da capacidade funcional foram feitos testes de desempenho, como Timed Up and Go (TUG), velocidade da marcha e teste de caminhada de seis minutos (TC6). Para avaliação da QV foram aplicados os questionários WOMAC e SF-36. Foi feita estatística descritiva e inferencial com o uso do software SPSS versão 20.0. Métodos: Os idosos com OA foram divididos em dois grupos (obesos, n = 16) e (não obesos, n = 19). As características sociodemográficas foram similares entre os grupos (p > 0,05). Foi observada redução de desempenho no TUG, velocidade da marcha rápida e TC6, com maior intensidade de dor nos itens: “executar tarefas domésticas pesadas”, “descer escadas”, “curvar-se em direção ao chão” e “levantar-se da cama” no grupo dos obesos (p < 0,05). Além disso, o grupo de obesos apresentou maior dificuldade ao executar tarefas para os itens: “descer escadas”, “levantar da cadeira”, “ficar de pé” e “sentar/levantar do vaso sanitaria” (p < 0,05). Não foi observada diferença estatisticamente significativa nos domínios avaliados do SF-36 entre os grupos (p > 0,05). Conclusão: A OA associada à obesidade impactou negativamente a capacidade functional. Entretanto, os escores de QV foram baixos sem diferença para obesos e não obesos.

Investigação da ansiedade, depressão e qualidade de vida em pacientes portadores de osteoartrite no joelho: um estudo comparativo / Investigation of depression, anxiety and quality of life in patients with knee osteoarthritis: a comparative study

RESUMOIntrodução:A osteoartrite (OA), artrose ou osteoartrose acomete a cartilagem hialina e o osso subcondral e compromete a articulação como um todo. A articulação do joelho caracteriza-se como um dos principais sítios de acometimento da OA. O envelhecimento, o sobrepeso e o gênero (prevalência em mulheres) são os fatores de risco mais significativos para o desenvolvimento da doença. A OA é considerada uma das mais frequentes causas de incapacidade laborativa e pode afetar a qualidade de vida de seus portadores e favorecer a emergência de transtornos mentais.Objetivo:Avaliar se os sintomas de ansiedade e depressão são mais expressivos em mulheres com OA quando comparados com mulheres sem tal diagnóstico e o quanto essa doença reumática compromete a qualidade de vida desses pacientes.Métodos:Participaram deste estudo 75 mulheres, com média de 67 anos, 40 com diagnóstico de OA no joelho e 35 sem. Foram usados os seguintes instrumentos: Inventário de Ansiedade Traço e Estado, Inventário de Depressão de Beck e SF-36, questionário de qualidade de vida.Resultados:Mulheres portadoras de OA no joelho têm níveis maiores de depressão e ansiedade, além de apresentar qualidade de vida inferior em comparação com o grupo sem a doença.Conclusão:Acreditamos que o tratamento aos portadores de OA deveria considerar a combinação de farmacoterapia, psicoterapia, orientação e apoio por parte dos parentes e/ou pessoas próximas para que o paciente possa atingir melhor qualidade de vida.

ABSTRACTIntroduction:Osteoarthritis (OA) affects the articular cartilage and subchondral bone, compromising the joint as a whole. The knee joint is characterized as one of the main sites of involvement of OA and the most significant risk factors for developing the disease are aging, overweight and female gender. OA is considered one of the most frequent causes of disability, which may affect the quality of life of the patients, favoring the onset of mental disorders.Objective:To investigate whether anxiety and depression symptoms are more significant in women with OA, when compared with women without this diagnosis, and to what extent this rheumatic disease affects the quality of life of these patients.Methods:The study included 75 women, mean age 67 years; 40 were diagnosed with knee OA and 35 without this diagnosis. The following instruments were used: State-Trait Anxiety Inventory (STAI), Beck Depression Inventory (BDI) and SF-36, a quality of life questionnaire.Results:Women with knee OA have higher rates of depression and anxiety when compared to controls; in addition, they have a lower quality of life.Conclusion:We believe that the treatment of patients with OA should consider the combination of pharmacotherapy, psychotherapy, counseling and family support, in order to achieve a better quality of life.

Effects of depression and anxiety on quality of life of patients with rheumatoid arthritis, knee osteoarthritis and fibromyalgia syndrome / Efectos de la depresión y la ansiedad sobre la calidad de los pacientes con artritis reumatoide, osteoartritis de la rodilla y síndrome de fibromialgia

OBJECTIVE: To measure the effects of depression and anxiety on quality of life (QoL) in patients with rheumatoid arthritis (RA), knee osteoarthritis (OA) and fibromyalgia syndrome (FMS). METHODS: One hundred and fifty-four patients with RA, knee OA, and FMS who presented to the physical medicine and rehabilitation department were studied. For evaluation of the patients, Beck depression scale, Beck anxiety scale, and Short Form-36 were used. RESULTS: Twenty-two per cent of patients (n = 34) were diagnosed with of RA, 52.6% (n = 81) knee OA and 25.3% (n = 39) FMS. Except for the subscales, of physical and emotional role, there were statistically significant differences among diagnostic groups in the rest of the SF-36 subscales. In the physical functioning subscale, the highest score was obtained in the fibromyalgia group and the lowest in the RA group (p < 0.001). However, in the bodily pain subscale, the lowest score was recorded in the fibromyalgia group (p = 0.019). In all diagnostic groups, the scores of SF-36 subscales were significantly low in patients who scored above the threshold value of Beck depression scale (p < 0. 001). A strong negative correlation was detected between scores of Beck anxiety scale and the scores of all SF36 subscales in patients with RA and knee OA. On the other hand, in patients with FMS, anxiety scores correlated negatively with only physical and somatic function scores of SF-36. CONCLUSION: Quality of life is significantly low in patients with RA, knee OA and FMS, whose depression and/or anxiety scores are high. Therefore, these patients should be managed using a multidisciplinary approach including psychiatric support.

OBJETIVO: Medir los efectos de la depresión y la ansiedad sobre la calidad de vida (CdV) en pacientes con artritis reumatoide (AR), osteoartritis de la rodilla (OA) y síndrome de fibromialgia (SFM). MÉTODOS: Se estudiaron ciento cincuenta y cuatro pacientes con RA, OA de la rodilla, y, que acudieron al departamento de medicina física y rehabilitación. Para la evaluación de los pacientes se utilizaron la escala de depresión de Beck, la escala de ansiedad de Beck, y el cuestionario de salud SF-3. RESULTADOS: Al veintidós por ciento de los pacientes (n = 34) se les diagnosticó RA, al 52.6% (n = 81) OA de la rodilla, y al 25.3% (n = 39) SFM. Excepto para las subescalas del rol físico y emocional, hubo diferencias estadísticamente significativas entre los grupos diagnósticos en el resto de las subescalas del cuestionario SF-36. En la subescala del funcionamiento físico, la puntuación más alta se obtuvo en el grupo de fibromialgia y la más baja en el de RA (p < 0.001). Sin embargo, en la subescala de dolor corporal, la puntuación más baja se registró en el grupo de fibromialgia (p = 0.019). En todos los grupos diagnósticos, las puntuaciones de las subescalas del cuestionario fueron significativamente más bajas en los pacientes que obtuvieron puntos por encima del valor umbral de la escala de depresión de Beck (p < 0.001). Una fuerte correlación negativa fue detectada entre las puntuaciones de la escala de ansiedad de Beck y las puntuaciones de todas las subescalas del cuestionario SF-36 en pacientes con RA y OA de la rodilla. Por otro lado, en pacientes con SF, las puntuaciones de ansiedad tuvieron una correlación negativa con solo puntuaciones de función física y somática de SF-36. CONCLUSIÓN: La calidad de vida es significativamente mas baja en pacientes con RAD, OA de la rodilla y SFM, cuyas puntuaciones de depresión y/o ansiedad son elevadas. Por lo tanto, estos pacientes deben de ser tratados haciendo uso de enfoques multidisciplinarios, incluyendo apoyo...

Comparison of validity, and responsiveness between general and disease-specific quality of life instruments (Thai version) in knee osteoarthritis.

Short-form 36 (SF-36) and Western Ontario and McMaster Universities Osteoarthritis index (WOMAC) are common instruments for measuring quality of life (QoL) in patients with knee osteoarthritis. The goal of the present study was to compare the performance of both instruments in evaluating QoL in patients with knee osteoarthritis as diagnosed by the American College of Rheumatology (ACR) criteria. Treatment included nonsteroidal anti-inflammatory drugs and patient education for 6 weeks. Face-to-face interview by an orthopaedist was done at baseline and after treatment, including collection of demographic data and use of both SF-36 and WOMAC questionnaires. Evaluation of instrument performance included reliability, validity, and responsiveness measures. Reliability was tested by analysis of internal consistency using Cronbach's alpha at baseline and after treatment. Construct validity was computed by determining the correlation between each domain of SF-36 and WOMAC (Pearson's test). Responsiveness was compared between baseline and after treatment of both SF-36 and WOMAC in each domain using the paired t test. Fifty-two patients (8 men, 48 women) with a mean age of 58.4 years were included in the present study. About 75% of subjects had less than secondary education levels and most were from agricultural communities. Sixty-four percent had mild grade knee osteoarthritis. The internal consistency of WOMAC revealed good levels of reliability, both at baseline and after treatment, in all dimensions. The reliability of SF-36 was relatively low, especially in the role physical and bodily pain dimensions (Cronbach's alpha < 0.700). Construct validity between each dimension in SF-36 and WOMAC demonstrated coefficients ranging from -0.05 to -0.409. Both WOMAC and SF-36 showed good responsiveness when comparing scores before and after treatment in all domains. In conclusion, both the Thai version WOMAC and SF-36 were valid, reliable, and sensitive to change in evaluating QoL in Thai patients with knee osteoarthritis.
