Association between Menstruation-Related Symptoms and the Type of Stress in Japanese Female University Students : A Prospective Cohort Study from Admission to the Second Year

Menstruation-related symptoms in young women are associated with lifestyle factors such as stress. This study aimed to examine menstrual conditions, menstruation-related symptoms, and types of stress in Japanese female students from their first to second years of university and the association between menstruation-related symptoms and stress levels. This prospective longitudinal cohort study utilized a self-reported web survey with the Menstrual Distress Questionnaire (MDQ) at three timepoints (2, 8, and 14 months) following admission and continuing into the second year. Data from 33 out of 102 students, who were followed throughout the study period, were used for analysis. Results indicated a trend towards changes in menstrual regularity, with the lowest (48.5%) at timepoint 1 and the highest (72.7%) at timepoint 3, and significant changes in perceived bleeding amount. Stress related to study and academic performance was consistently highest, with significant differences across timepoints. Intra-menstrual MDQ scores were highest at timepoint 1, with significant variations in impaired concentration severity across timepoints. Significant correlations were found between the MDQ scores and stress related to health and personality at all timepoints, and to future prospects, friendships, study, and academic performance at different timepoints. In short, stress related to academic performance, along with a strong correlation between MDQ scores and specific stress types, such as health and personality, was observed across all timepoints. This implies the need to provide new students with health education regarding menstruation and stress management before specific timepoints.
