BACKGROUND: Findings of most studies indicate that the only way to control diabetes and prevent its debilitating effects is through the continuous performance of self-care behaviors. Physical activity is a non-pharmacological method of diabetes treatment and because of its positive effects on diabetic patients, it is being increasingly considered by researchers and practitioners. This study aimed at determining factors influencing physical activity among diabetic women in Iran, using the extended theory of reasoned action in Iran. METHODS: A sample of 352 women with type 2 diabetes, referring to a Diabetes Clinic in Khoy, Iran, participated in the study. Appropriate instruments were designed to measure the desired variables (knowledge of diabetes, personal beliefs, subjective norms, perceived self-efficacy, behavioral intention and physical activity behavior). The reliability and validity of the instruments were examined and approved. Statistical analyses of the study were conducted by inferential statistical techniques (independent t-test, correlations and regressions) using the SPSS package. RESULTS: The findings of this investigation indicated that among the constructs of the model, self efficacy was the strongest predictor of intentions among women with type 2 diabetes and both directly and indirectly affected physical activity. In addition to self efficacy, diabetic patients' physical activity also was influenced by other variables of the model and sociodemographic factors. CONCLUSION: Our findings suggest that the high ability of the theory of reasoned action extended by self-efficacy in forecasting and explaining physical activity can be a base for educational intervention. Educational interventions based on the proposed model are necessary for improving diabetics' physical activity behavior and controlling disease.

OBJECTIVES: A health-promoting lifestyle (HPL) is a factor that affects the quality of life (QoL) in patients with beta-thalassemia (β-thalassemia). Due to the lack of studies of this issue, this study aimed to determine the association between HPL and QoL among adults with β-thalassemia. METHODS: This cross-sectional (descriptive-analytic) study was conducted among 389 adult patients with β-thalassemia in Tehran, Iran. The research instrument included a questionnaire consisting of three parts: demographic items, the Short-Form Health Survey and the Health-Promoting Lifestyle Profile. The data were analyzed using SPSS version 23.0. The results were considered significant at the conventional p<0.05 level. RESULTS: The mean age of the participants was 30.2±8.3 years. The mean score of the HPL dimensions was 127.28±21.53, and the mean score of the QoL domains was 61.44±23.38. The highest and the lowest mean scores of the HPL dimensions were found for spiritual growth (23.96±5.74) and physical activity (11.32±3.95), respectively. The QoL scores in all three domains (total, physical component summary score, and mental component summary score) were moderate. Health responsibility, physical activity, spiritual growth, and interpersonal relations were significant predictive factors of QoL in adults with β-thalassemia; these four dimensions explained 37.9% of the variance in QoL. CONCLUSIONS: QoL and HPL were not at acceptable levels among patients with thalassemia. Therefore, educational interventions emphasizing spiritual growth, physical activity, and interpersonal relations are necessary for patients with thalassemia.

BACKGROUND: Considering the high prevalence of depression and anxiety among thalassemia patients and the role of social support in preventing mental disorders, this study aimed to determine prevalence of depression, anxiety, and perceived social support (PSS) among adults with beta-thalassemia major. METHODS: This cross-sectional study was performed with 389 adults with beta-thalassemia major. Data were collected via a questionnaire consisting of three parts: demographic and medical information, the Persian version of the hospital anxiety and depression scale, and the Persian version of the Multidimensional Scale of Perceived Social Support. Data were analyzed using IBM SPSS ver. 23.0 (IBM Corp., Armonk, NY, USA) through analytical statistics (independent-samples t-test, one-way analysis of variance, Pearson correlation coefficient, and multilevel linear regression), and the results less than 0.05 were considered to be significant. RESULTS: The mean scores of depression, anxiety, and PSS of patients were 7.42±3.17, 7.47±4.35, and 41.8±8.64, respectively. Of 389 patients, 19.8% had depression and 23.7% had an anxiety disorder. Relationships of depression and anxiety with age, the level of education, job, and family income were statistically significant, as were those of PSS with age, thalassemia center, family income, job, and the level of education. PSS from family, friends, and significant others were the significant predictive factors of depression and anxiety among adult patients with beta-thalassemia major. CONCLUSION: Considering the PSS as a factor influencing the reduction in depression and anxiety in thalassemia patients, social support from the social networks (spouse, family members, friends, and healthcare workers) should be integrated with interventions that are designed to improve the mental and physical health of thalassemia patients.
