 Background: Dysmenorrhea is a menstrual disorder in the world, affecting approximately 40-90% of women. Various factors have been associated with its appearance such as age of menarche, menstrual period, childbirth, family history of dysmenorrhea, among others. In order to provide information (data) on epidemiological dysmenorrhea in Cameroon, some studies were done at the University of Dschang- Cameroon.  Methodology: Cross-sectional descriptive study using self- administered questionnaire.  Results: The prevalence of dysmenorrhea among 689 young dysmenorrheic university students in this study was 63.86%. The percentage distribution for the various degrees of severity of dysmenorrhea in 440 students was 12.95%, 54.09%, and 25.90% for mild, moderate and severe dysmenorrhea respectively. About 23.10% of respondents with dysmenorrhea had absented themselves from class at some time, with 20.51% to lectures, 1.65% TD/TP and 0.94% to exams. The risk of having dysmenorrhea was 4.29 times in the participants who had a family history of dysmenorrhea (OR = 4.29, 95% CI 1.09 to 6.02), and this risk is higher when menstrual bleeding occurs for more than 7 (seven) days (72.22%).  Conclusion: Dysmenorrhea is a disease that has a high prevalence and significant impact on absenteeism from campus. Family history of dysmenorrhea and menstrual bleeding time were most positively associated with dysmenorrhea. The correct approach to manage girl students with dysmenorrhea can reduce the adverse impact of severe dysmenorrhea on academic activities in the form of class absenteeism.
