    Female athletes experience more menstrual irregularities like irregular cycles and amenorrhoea (O/A) than non-athletes. This dysfunction is linked to low body fat, weight, and sports-related stress.

    Area of Science:

    • Sports Medicine
    • Reproductive Endocrinology
    • Exercise Physiology

    Background:

    • Menstrual dysfunction is a concern in female athletes.
    • Athletic training can impact hormonal balance and reproductive health.

    Purpose of the Study:

    • To compare menstrual function between Nigerian athletes and non-athletes.
    • To identify factors associated with menstrual dysfunction in athletes.

    Main Methods:

    • Cross-sectional study involving 475 Nigerian athletes and 606 non-athletes.
    • Assessment of menstrual cycle regularity, oligomenorrhoea, and secondary amenorrhoea (O/A).
    • Analysis of associations between menstrual dysfunction and body composition, weight, and training factors.

    Main Results:

    Related Experiment Videos

    • Athletes showed higher rates of irregular cycles (26%) and O/A (21%) compared to non-athletes (18% and 8%).
    • Normal menstruation was less frequent in athletes (22%) than non-athletes (50%).
    • Menstrual dysfunction correlated with low body fat, low body weight, and sports stress; distance runners and ball game players had higher O/A rates, while swimmers and sprinters reported more dysmenorrhoea and menorrhagia.

    Conclusions:

    • Athletic participation, particularly in certain sports and pre-menarche training, is associated with increased menstrual dysfunction.
    • Low body fat, low body weight, and psychological stress are significant contributing factors to menstrual irregularities in athletes.
