Menstrual period is a critical time in the life of females. For the first few years after menarche, irregular cycle is common due to premature hypothalamic-pituitary ovarian (HPO) axis physiologically. If persistent, it becomes a major problem in student's life. But few studies conducted on effect of menstrual cycle irregularity on academic performance among university students were descriptive. However assessing the effect of menstrual irregularity on academic performance by using average grade point approach is critically important to magnify its effect.
To compare effects of menstrual irregularity on academic performance among undergraduate students of Debre Berhan University, Ethiopia 2020.
A comparative cross sectional study was conducted among 404 students in Debre Berhan University, Ethiopia, 2020. A standard tool of menstrual cycle regularity which is prepared by international federation of gynecologist and obstetrics (IFGO) was used to screen students who have menstrual irregularity. Independent sample t- test was done to compare the mean difference of academic performance between the two groups of students.
The age of study participants ranges between 18 and 26 years with a mean age of 20.69 ± 1.43 years. The mean age at menarche was 14.9 ± 1.67 ranging from 9 to 18 years. Students who had menstrual irregularity had mean average grade point (AGP) of (2.78 ± 0.57) and students who had regular menstruation had mean AGP of (2.97 ± 0.53). Students who had menstrual irregularity had lower mean average grade point by a mean difference of 0.19 (95%CI: 0.09-0.30).
This study found that students who had menstrual irregularity had significantly lower mean AGP as compared with students who had regular menstruation.
月经是女性生命中的一个关键时期。由于下丘脑-垂体-卵巢（HPO）轴在生理上尚未完全成熟，初潮后的最初几年，周期不规律是很常见的。如果持续存在，它将成为学生生活中的一个主要问题。但是，很少有研究探讨月经不规律对大学生学业成绩的影响，且这些研究大多是描述性的。然而，通过平均绩点法评估月经不规律对学业成绩的影响对于放大其影响至关重要。
比较 2020 年埃塞俄比亚德布雷贝汉大学本科生月经不规律对学业成绩的影响。
2020 年，在埃塞俄比亚德布雷贝汉大学对 404 名学生进行了一项横断面比较研究。采用国际妇产科联合会（IFGO）制定的月经周期规律标准工具筛选出月经不规律的学生。采用独立样本 t 检验比较两组学生学业成绩的平均差异。
研究参与者的年龄在 18 至 26 岁之间，平均年龄为 20.69 ± 1.43 岁。初潮年龄为 14.9 ± 1.67 岁，范围为 9 至 18 岁。月经不规律的学生平均绩点（AGP）为（2.78 ± 0.57），月经规律的学生平均 AGP 为（2.97 ± 0.53）。月经不规律的学生平均 AGP 低 0.19 分（95%CI：0.09-0.30）。
本研究发现，与月经规律的学生相比，月经不规律的学生平均 AGP 显著较低。
