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.

Background and Objective:‌One of the most common complications of IUD users is dysmenorrhea, which is not the same in different IUDs. The aim of this study was to compare the dysmenorrhea in IUD multi-load 375 and IUD copper T 380 A.
Material and Methods: ‌‌A randomized double- blinded controlled clinical trial was conducted on 48 women referring to a health-center ‌in Tabriz, from 2011jan-2012 oct.The participants ‌were randomly allocated to two groups of multi-load 375 IUD and the copper T 380A IUD ( located in a four-member and six-member block).We measured the amount of dysmenorrhea with Visual Analog Scale , before the IUD insertion and four mouths later. The data was analyzed by SPSS-13, using Mann-Whitney, Regression, Fridmans test.
Results: The results showed that the severity and duration of dysmenorrhea in two groups of IUD were significantly different, considering ‌the factors such as the baseline dismenorrhea‌, the utilized drug and the interval between the last labor and IUD insertion.The dysmenorrhea in multi-load group was decreased and in copper T increased significantly.
Conclusion: Based on the results , multi-load IUD results in considerable reduction in the severity and duration of dysmenorrhea. Therefore, it is reccomended counseling about both multi-load IUD and Copper T in the family planning service centers.
