Quality of life among Iranian patients with beta-thalassemia major using the SF-36 questionnaire.

CONTEXT AND OBJECTIVE Patients with beta-thalassemia major (ß-TM) experience physical, psychological and social problems that lead to decreased quality of life (QoL). The aim here was to measure health-related QoL and its determinants among patients with ß-TM, using the Short Form-36 (SF-36) questionnaire. DESIGN AND SETTING Cross-sectional study at the Hematology Research Center of Shiraz University of Medical Sciences, in southern Iran. METHODS One hundred and one patients with ß-TM were randomly selected. After the participants' demographics and disease characteristics had been recorded, they were asked to fill out the SF-36 questionnaire. The correlations of clinical and demographic factors with the QoL score were evaluated. RESULTS There were 44 men and 57 women of mean age 19.52 ± 4.3 years (range 12-38). On two scales, pain (P = 0.041) and emotional role (P = 0.009), the women showed significantly lower scores than the men. Lower income, poor compliance with iron-chelating therapy and presence of comorbidities were significantly correlated with lower SF-36 scores. These factors were also found to be determinants of worse SF-36 scores in multivariate analysis. CONCLUSIONS We showed that the presence of disease complications, poor compliance with iron-chelating therapy and poor economic status were predictors of worse QoL among patients with ß-TM. Prevention and proper management of disease-related complications, increased knowledge among patients regarding the importance of managing comorbidities and greater compliance with iron-chelating therapy, along with psychosocial and financial support, could help these patients to cope better with this chronic disease state.

Quality of life among Iranian patients with beta-thalassemia major using the SF-36 questionnaire / Qualidade de vida em pacientes iranianos com beta-talassemia maior usando o questionario SF-36

CONTEXT AND OBJECTIVE Patients with beta-thalassemia major (β-TM) experience physical, psychological and social problems that lead to decreased quality of life (QoL). The aim here was to measure health-related QoL and its determinants among patients with β-TM, using the Short Form-36 (SF-36) questionnaire. DESIGN AND SETTING Cross-sectional study at the Hematology Research Center of Shiraz University of Medical Sciences, in southern Iran. METHODS One hundred and one patients with β-TM were randomly selected. After the participants' demographics and disease characteristics had been recorded, they were asked to fill out the SF-36 questionnaire. The correlations of clinical and demographic factors with the QoL score were evaluated. RESULTS There were 44 men and 57 women of mean age 19.52 ± 4.3 years (range 12-38). On two scales, pain (P = 0.041) and emotional role (P = 0.009), the women showed significantly lower scores than the men. Lower income, poor compliance with iron-chelating therapy and presence of comorbidities were significantly correlated with lower SF-36 scores. These factors were also found to be determinants of worse SF-36 scores in multivariate analysis. CONCLUSIONS We showed that the presence of disease complications, poor compliance with iron-chelating therapy and poor economic status were predictors of worse QoL among patients with β-TM. Prevention and proper management of disease-related complications, increased knowledge among patients regarding the importance of managing comorbidities and greater compliance with iron-chelating therapy, along with psychosocial and financial support, could help these patients to cope better with this chronic disease state. .

CONTEXTO E OBJETIVO Pacientes com beta-talassemia maior (β-TM) vivenciam problemas físicos, psicológicos e sociais que levam à diminuição da qualidade de vida (QV). O objetivo foi determinar a QV relacionada à saúde e seus determinantes em pacientes com β-TM, utilizando questionário SF-36 (Short Form-36). TIPO DE ESTUDO E LOCAL Estudo transversal no Centro de Hematologia e Pesquisa em Universidade de Ciências Médicas de Shiraz, no sul do Irã. MÉTODOS Foram selecionados aleatoriamente 101 pacientes com β-TM. Após registro demográfico e características da doença, eles foram convidados a preencher o questionário SF-36. A correlação entre fatores clínicos e demográficos com escore de QV foi avaliada. RESULTADOS Havia 44 homens e 57 mulheres, com idade média de 19,52 ± 4,3 (variação 12-38) anos. Em duas escalas, dor (P = 0,041) e aspectos emocionais (P = 0,009), as mulheres apresentaram escores significativamente menores aos dos homens. Menor renda, baixa adesão à terapia quelante de ferro e presença de comorbidades foram correlacionadas com escores SF-36 significativamente menores. Esses fatores foram também considerados determinantes de piores escores de SF-36 em análise multivariada. CONCLUSÕES Mostramos que a presença de complicações da doença, a baixa adesão ao tratamento da terapia quelante de ferro e o baixo status econômico são preditores de pior QV em pacientes com β-TM. Prevenção e manejo adequado das complicações relacionadas com a doença, aumento do conhecimento dos pacientes sobre a importância do gerenciamento de comorbidades e ter maior adesão ao tratamento quelante de ferro, considerando também ...
