Magnitude and associated factors of menstrual irregularity among undergraduate students of Debre Berhan University, Ethiopia

BACKGROUND: Menstrual irregularity is a common problem among women aged from 21 to 25years. Previously published work on menstrual irregularity used inconsistent definition which results in a difference in prevalence. Therefore the study aimed to assess the magnitude and associated factors of menstrual irregularity among undergraduate students of Debre Berhan University, Ethiopia. METHODS: A cross-sectional study design was carried out among 660 undergraduate female students at Debre Berhan University. To get representative study participants, a stratified sampling technique was used. To collect the data self-administered questionnaire was used. Physical examination and anthropometric measurement were also done. Data were analyzed by using SPSS version 21. Logistic regression analysiswas done. A significant association was declared at a p-value less than 0.05. RESULT: A total of 620 students participated in the present study with a response rate of 93.9%. Out of the total study participants, 32.6% (95% CI 2936.5) participants had irregular menstrual cycle. Significant association was found between anemia (AOR=2.1; 95%CI 1.3373.441), alcohol intake (AOR=2.4; 95%CI 1.254.666),<5 sleep hours (AOR=5.4; 95%CI 2.9759.888), 67 sleep hours (AOR=1.9; 95%CI 1.2912.907), Perceived stress (AOR=3.3; 95%CI 1.83225.940), iodine deficiency disorder (IDD) (AOR=3.9; 95%CI 1.32511.636) and underweight (AOR=1.8; 95%CI 1.1092.847) with menstrual irregularity. CONCLUSION: The finding of this study reported a low magnitude of menstrual irregularity as compared to previous studies. Students should adopt healthier lifestyle practices (weight control, stress control, anemia control, and avoid alcohol intake) to control menstrual irregularity.
