BACKGROUND: Dysmenorrhea is one of the most common gynecologic disorders and a frequently observed cause of anxiety and discomfort among female adolescents. Its prevalence varies between 16% and 91% in women of reproductive age. Its population statistics are too scant in Ethiopia. This study was aimed to determine the prevalence and associated factors of dysmenorrhea among secondary and preparatory school students in Debremarkos town, 2016. METHODS: Institutional based cross-sectional study was employed from Sept.26 to Oct.17, 2016 among secondary and preparatory school students in Debremarkos town. Self-administered questionnaire was used to collect data from 539 individuals selected by simple random sampling technique. Data were checked, coded and entered into Epi-data version 3.1 and exported to SPSS version 20 for analysis. Univariate, bivariate and multivariable analysis were carried out. Binary logistic regression model was computed and P value < 0.05 was considered as significant. All ethical procedures were considered. RESULTS: The prevalence of dysmenorrhea was 69.3%. Age, AOR (95% CI) =1.38(1.15, 1.65), family history of dysmenorrhea, AOR (95% CI) = 9.79(4.99, 19.20), physical activity, AOR (95% CI) =0.39(0.13, 0.82), sugar intake, AOR (95% CI) =2.94 (1.54, 5.61), early menarche AOR (95% CI) =4.10(1.21,13.09), late menarche AOR (95% CI) =0.50 (0.27, 0.91), heavy menstrual periods AOR (95% CI) =2.91(1.59, 5.35) and sexual intercourse AOR (95% CI) =0.24 (0.10.0.55) had statistically significant association with the occurrence of dysmenorrhea.
