Background and Objective: Hydrogenated vegetable oils consumption ­–­rich sources of both saturated ­fatty acids and trans fatty­ acids is one of the most important risk factor for Coronary Vascular Diseases(CVD) .The aim of the current ­study was to investigat the hydrogenated vegetable oil consumption based on Precede model among women who attained in Khomein and Mahallat health centers in 2008.

  Material and Methods: In this descriptive-analytic a study, 136 women who were covered ­by Khomein and Mahallat health centers selected through a systematic random sampling. Data gathering instrument was a researcher-­designed valid and reliable questionnaire bases on Precede constructs. The data was analyzed by using independent T-test and Pearson correlation coefficient(p<0.05).
Results: Three point five percent have appropriate knowledge, 60.3% have favorite attitude and 67.7% have­ incorrect practice. Hydrogenated vegetable oil consumption rate is 72%.The expensive ­of unhydrogenated oil 77.9% and­ subsiding­ distribution­ of hydrogenated oil 77% are the most important enabling­ factors.­ Meanwhile, husband unwelcoming 66.2% is the most reinforcing factor that impede as an appropriale practice. 

  Conclusion: The­ results­ indicated­ that the­ majority of subjects have inappropriale nutritional practice. Reinforcing and enabling factors­ are effective on unhydrogenated oil consumption. Decrease­ of unhydrogenated oil price and encouragement of the spouses are recommended.

  Background and Objective: Understanding and improving traffic behaviors, especially, the use of helmet is known as a strategy for preventing from road accidents. prevention of road accidents are caused Azsdma The aim of ­the present study was to assess the barriers to helmet use, based on health belief model in Khomein city.

  Material and Methods: ­ The subjects of this Cross-­sectional study were 384 drivers recruited via convenience sampling.­­The instrument was a research-made questionnaire based on HBM items.­The data related to performance, Perceived susceptibility, Perceived barriers, Perceived severity ­and Perceived benefits were analyzed by­ independent T-test,­Pearson, spearman correlation, chi square and wilcoxon (p≤0.05).

  Results: The barriers to helmet use are sweating, decreased hearing, expensiveness, heaviness, and visual limitation, ­chocking feeling, hairstyle, losing ­the helmet, shyness and time consuming, respectively. ­The rate of helmet use is 16.2%. ­According to the the subjects, ­education­(61.4%) paying fines (22.7%) and confining motorcycles (15.9%) are effective on wearing helmet.

  Conclusion:­ ­ According to the results, we recommend performing proper educational programs about wearing helmet, based­ on HBM,­­ designing new helmet by considering fore mentioned problems and modifying police treatments toward education.

Background and Objective:  Transtheoretical model (TTM) is one of the models applied to  assess the regular physical activity. The aim of the current study was to investigate the regular physical activity based on transtheoretical model constructs among Golestan University of Medical Sciences’ students.

Material and Methods: ­In this cross-sectional study, 295 students were recruited through convenience sampling. The instruments were Marcos et al. Stages of change and Nigg et al. Decisional balance questionnaires. Their validity was approved by content and face validity andtheir reliability by test re test method.­­ Data analysis was conducted by Chi-­square ,Logestic regression, and ANOVA followed by Tukey post hoc tests.

Results:­ The mean age of the participants is 21.89±3.05.­Eighty nine point five percent are unmarried and 67.5% females .The results show that they are in precontemplation (60.3%) contemplation(8.8%), preparation(11.9%), action(9.5%)­ and maintanenec (9.5%)stages. There is a significant relationship between stage of change with cons and pros of physicalactivity(p<0.05) .Male gender, Bsc and lower educational levels along with cons are the best predictors of regular physical activity(p<0.05).

Conclusion: Since the majority of the students(81%) have a  sedentary life, It is a necessity to conduct some  planned interventions for their progress on maintenance stage. Increasing of pros and decreasing of cons could be useful.
