The paramenstrual syndrome was studied among 220 women in Monoufia governorate of 15-35 years of age. The modified Moos Menstrual Questionnaire was used to record the prevalence rates of the different symptoms. The most common somatic symptom was backache and psychological symptom was irritability. Somatic symptoms rates surpassed the psychological ones. Almost all symptoms subsided during the menstrual phase. Education, occupation, crowding index, high tension field, and menstrual cycle characteristics were associated more with the severity of nearly all symptoms. It was recommended that proper examination of women should be done to detect medical and legal problems related to this syndrome which would benefit from hormonal treatment and assurance. Further investigations have to be done to determine the prevalence rates of paramenstrual syndrome among the Egyptian women and the factors affecting their aggravation
