Prevalence of premenstrual syndrome and some of its relative factors in reproductive age

Premenstrual syndrome (PMS) is a periodically experience of specific physical and psychological symptoms in the last few days of the menstrual cycle. These symptoms are severe and very disabling in some women and interfere with their career، social function and family relations. In this study we aimed to evaluate the prevalence of premenstrual syndrome and some of its relative factors. This cross sectional community based study was performed in 2009-2010 in population of 18-45 year old Iranian women. 1200 samples were selected using the stratified، multistage probability cluster sampling method. Used questionnaire was based on the standard of Americam Colledge of Women and Midwifery. Statistical analysis was performed using Chi-square and logistic regression tests by SPSS 15 software. 52. 9% of samples were suffered from premenstrual syndrome and 34. 5% of them were suffered from its severe type. Premenstrual syndrome had a significant relation with each age، education status and career of samples but hadn’t any significant relation with marriage status and number of deliveries. Age groups and educational status were potential to predict premenstrual syndrome. PMS affects more than half of reproductive aged women and this disorder is more prevalent in aged and more educated women.
