Summary

Intensive dance training led to a 32% incidence of menstrual dysfunction in teenage students. Pre-existing hormonal imbalances, specifically a higher LH/FSH ratio and DHEAS levels, identified students at higher risk.

Area of Science:

  • Sports Medicine
  • Endocrinology
  • Adolescent Health

Background:

  • Menstrual dysfunction is a concern in athletes, particularly in disciplines requiring low body weight.
  • Understanding risk factors in adolescent dancers is crucial for early intervention.

Purpose of the Study:

  • To assess the impact of intensive dance training on menstrual function in teenage students.
  • To identify predictors of menstrual dysfunction in this population.

Main Methods:

  • 50 adolescent dance students were assessed at baseline and after 12 months of intensive training.
  • Data collected included menstrual history, anthropometrics, body composition, hormonal profiles, and psychological assessments.
  • Menstrual patterns, self-image, and body fat were re-evaluated after 12 months.

Main Results:

  • 32% of students developed menstrual dysfunction (amenorrhea or oligomenorrhea) after training.
  • A reduction in weight and body fat was observed, but did not differentiate between groups.
  • Pre-training, students with subsequent dysfunction had higher LH/FSH ratios and DHEAS levels.

Conclusions:

  • Intensive dance training is associated with a high incidence of menstrual dysfunction in adolescent students.
  • Pre-existing hormonal predispositions may increase susceptibility to menstrual dysfunction in dancers.
