Background and Objective: Cardiovascular diseases are a main reason of disability and death around the world. Evidence suggests that many social and individual-based health-related factors are changeable and modifiable. The aim of this study was to evaluate the effect of a theory-based intervention based on the health belief model on health-promoting lifestyle behaviors in individuals susceptible to cardiovascular diseases. Materials and Methods: In this quasi-experiment, we recruited 180 individuals having at least two risk factors out of five cardiovascular risk factors, including smoking, diabetes, hypertension, high cholesterol, and obesity. Data were gathered in three phases (before, immediately after, and five months after implementing the intervention) using the health-promoting lifestyle questionnaire (HPLQ), general health questionnaire (GHQ), and a designed questionnaire to measure the health belief model constructs. The intervention included five training sessions based on the health belief model. Data were analyzed using the statistical tests in the SPSS. Results: Findings showed that the theory-based educational intervention was effective in improving some domains of lifestyle, including nutrition, physical activity, interpersonal relationships, stress management and health accountability. Also, the mean blood pressure and the mean tobacco use showed a significant decrease in the intervention group after the intervention. Educational intervention also led to improvements in health belief model constructs including perceived susceptibility, perceived severity and perceived benefits (P

Objective (s): Physical inactivity is one of the biggest public health concerns. Due to various reasons such as pregnancy, women are more at risk of physical inactivity. This study performed to determine the influence of an educational intervention on promoting postpartum physical activity based on BAZNEF model, among women referred to health centers. Methods: This was a quasi-experimental study which conducted on 168 women referred to health centers during six weeks to one year after delivery. Samples divided in two groups; intervention and control by using a random allocation. Data collected by BASNEF questionnaire and International Physical Activity Questionnaire(IPAQ).. The educational intervention was designed in four sessions. Control group received no intervention except postpartum routine care. Three months after intervention, the questionnaire was completed again in two groups. Results: Pretest results revealed no significant differences in demographic characteristics and BASNEF model constructs in both groups (p>0/05). However, after intervention there was a significant differences between two groups in terms of BASNEF model including knowledge, attitude, normative believes, enabling factors and intention (P

Background: By considering, transactional model is one of the most comprehensive model for reduction of stress, this study was determined the role of Transactional Model constructs in Yazd teachers of Primary school by using of Structural Equation Model. Methods: This research was a descriptive- analytical. Categorized approach was applied for sampling. A standard questionnaire and the questionnaire planned based on Transactional Model were applied for data collection. Validity (CVR=0.85) and reliability (α=0.87) of instrument confirmed by experts. SPSS15 and LISREL8.8 software were used for data analysis. Results: In this research 200 Yazd teachers of primary schools (average age of 41.70±5.69) were participated. The results of this study showed the effect of stress on secondary appraisal and primary appraisal was -0.87 and 0.84, respectively. Our results also showed an inverse relationship between perceived stress and secondary appraisal also between primary appraisal and coping effort. Also, the results were confirmed validity and good fitness of model, because of the RMSEA=0.0329 and index χ2/df were less than 3. Conclusion: Since the constructs of this model had a significant effect on the stress, it suggests the policies and plans for improvement of these factors.
