RESUMO
Background: Diabetes type 2, as one of the most important chronic diseases in the world, reduces quality of life in patients. Materials and Methods: Our research - as a descriptive analytical cross-sectional study - was performed on 120 type 2 diabetics in Tehran 503 hospital in 2008. Diverse domain scores of patients' quality of life were evaluated by SF-36 standard questionnaire. Gained data analyzed by SPSS 16.0 software through statistical tests including Pearson's correlation coefficient, Chi-square test, Independent T-test, Kolmogrov-Smirnov test, Mann-Whitney test, Kruskal Wallis test, ANOVA, and Fisher exact test. Results: Age had significant reverse relationship with physical functioning, vitality, mental health, and mental component score. Education level was just directly correlated to bodily pain. Marital status was correlated with social functioning and general health domains. Family income level was directly related to mental health and mental component score domains. No relation was found between years of disease duration, smoking status, workout status, diet follow-up, lack/presence of hypertension, and diverse domains of these patients' quality of life. Hyperlipidemia had meaningful reverse relationship to physical functioning, bodily pain, social functioning, and physical component score domains. Heart diseases had meaningful reverse relationship to physical functioning and mental health domains. Patients' physical component score had direct relationship to mental component score. Conclusion: Observed scores were meaningfully low in comparison with both healthy people and similar surveys.
