Dysmenorrhea is the most common gynaecological problem among young females. In Arabic countries, few studies on gynaecological problems of adolescent’s girls were published. Objective: the aim of the study was to determine the prevalence of dysmenorrhea and associated factors among adolescents in public schools at Marrakesh. Methods: we conducted a cross-sectional study; our data was collected via a questionnaire and the statistical analysis was done using SPSS version 21. Our random sample counted 364 post-menarcheal girls aged between 12 and 20 years who participated voluntarily in our study. Results: the mean age at menarche was 12.89 ± 1.34 years; the prevalence of dysmenorrhea was 78% and 58.1% of them suffering from severe dysmenorrhea that increased clearly with the chronological age. Dysmenorrhea was cause for missing school among 13% of girls and the most common symptoms associated with it were backache, fatigue, irritability and anxiety. The gynecological age was found to be the only predictive factor of dysmenorrhea among schoolgirls. Conclusion: reproductive health education should be improved enough by including them in the school curriculum to prepare girls for menstruation and inform them about problems related to this phenomenon, especially dysmenorrhea.
