Introduction: Premenstrual syndrome (PMS), is known as periodic changes in physical, cognitive, behavioral and mood condition. These change could be so sever to interrupt patient's daily life. If PMS causes disruption in family attendance of patients its name changes to premenstrual dysphoric syndrome (PMDD). Given the effects of menstrual disorders on women's life in our country we aimed to investigate the prevalence of PMDD among students of Zahedan University of Medical Sciences.

Material and methods: This was a cross-sectional study conducted on 193 students studying in Zahedan University of Medical Sciences on 2015. Data was collected through standard PSTT questionnaire. The validity and reliability of this questionnaire has proved in Iran. Finally after collecting the data they were analyzed by SPSS v.19 and through descriptive statistics, chi-square test, Fisher's exact test and t test.

Results: The mean age was 21.56±2.68 among respondents. There wasn’t any significant relationship between PMDD and bleeding time (P>0.05). There was a significant relationship between PMDD and family history (P=0.02). Moderate to severe irritability and nervousness (100%) and problems in relations with family members (97.1%) were the most common signs of PMDD in this study.      

Conclusion: This study had shown that PMS has a high prevalence among students in Zahedan University of Medical Sciences. This should be reduced by increasing knowledge about these signs among students by teaching them about this matter. Proper therapeutic methods for these patients should be conducted to prevent more problems in PMDD.
