Introduction: Premenstrual syndrome is a common disorder in reproductive age and it is associated with decreased quality of life in women. In view of various factors contributing to outbreak of PMS (premenstrual syndrome) among women, the present study intended to compare lifestyles of university students with and without premenstrual syndromes living in dormitories of Qazvin University of Medical Sciences in 2015.

Methods: The descriptive cross-sectional study recruited 200 university students with and without PMS from students living in dormitories. Data were collected using questionnaires of premenstrual symptoms, questionnaires for diet, perceived stress, and unhealthy behavior. Data were analyzed using descriptive statistics, independent samples t-test, Mann-Whitney, Chi-square, and logistic regression in SPSS version 23. 

Results: The results showed that nutrition style (p=0.001), perceived stress (p=0.001), and exposure to passive tobacco smoke (p=0.001) were different between the two groups. Logistic regression analysis showed that nutrition style (p=0.001, OR=0.861), exposure to passive tobacco smoke (p=0.008, OR=2.059), and stress (p=0.001, OR=1.088) were different in both groups.

Conclusion: The research results proved that lifestyle, especially healthy eating habits, and decreasing stress and unhealthy behavior can influence PMS. Therefore, interventions are recommended to improve PMS symptoms.

The worldwide spread of COVID-19 as an emerging, rapidly evolving situation, and the dramatic need of urgent medicine or vaccine, has rapidly brought new hypotheses for pathophysiology and potential medicinal agents to the fore. It is crucial that the research community provide a way to publish this research in a timely manner.


To contribute to this important public health discussion, the Electronic Physician Journal is excited to announce a fast-track procedure to help researchers publish their articles on COVID-19 related subjects that fall under the broad definition of public health, internal medicine, and pharmacology. We are especially welcome to all hypotheses about the pathological basis of the COVID-19 infection and the possible characteristics of potential medicine and vaccine. Submit your manuscript here
