- High stress levels were associated with increased risk of menstrual irregularity.
- Depressive mood was associated with increased risk of menstrual irregularity.
- Psychological counseling was related with increased risk of menstrual irregularity.
- These associations were independent of confounding factors.
- More attention should be paid towards mental health, to improve menstrual regularity.

BackgroundMenstrual cycle irregularity is common among adolescents and can induce mental health problems such as stress, depression, and suicidal ideation. We examined the association between mental health problems and menstrual cycle irregularity among adolescent Korean girls.MethodsThis population-based cross-sectional study was on 808 female adolescents (12-18 years of age) participating in the 2010-2012 Korean National Health and Nutrition Examination Survey. Psychological stress, depressive mood, suicidal ideations, suicide attempts, and psychological counseling were assessed through questionnaires and surveys, and hierarchical multivariable logistic regression analysis was performed.ResultsThe risk of menstrual cycle irregularity tended to increase, as the number of mental health problems increased (P for trend=0.016). High stress levels, depressive mood, and psychological counseling were associated with increased risks of menstrual cycle irregularity (odd ratio [95% confidence interval]=1.88 [1.1-3.21], 2.01 [1.01-4.03], and 2.92 [1.16-7.34], respectively) even after adjusting for age, body mass index, alcohol consumption, smoking status, physical activity, hemoglobin level, monthly household income, weight loss attempts, age at menarche, and sleep duration. Suicidal ideation was not significantly associated with menstrual cycle irregularity.LimitationsMenstrual irregularity was evaluated based solely on subjects' self-reports, which are subject to their subjective perceptions and appraisal. Cross-sectional design and retrospective data could not draw causal relationship.ConclusionsPositive associations were observed between mental health problems and menstrual cycle irregularity among adolescent Korean girls. More attention should be paid towards mental health, to improve menstrual cycle regularity and help prevent related chronic diseases later in life.
