Early pubertal timing is a risk factor for adolescent dysmenorrhea

Area of Science:

• Reproductive health
• Adolescent medicine
• Puberty research

Background:

• Early menarche is linked to increased dysmenorrhea risk.
• However, other pubertal development markers precede menarche.
• Understanding these earlier markers could improve risk prediction.

Purpose of the Study:

• To investigate the association between early pubertal timing and dysmenorrhea risk.
• To identify novel markers for dysmenorrhea risk beyond menarcheal age.

Main Methods:

• Utilized data from the Adolescent Brain Cognitive Development Study®.
• Estimated pubertal timing using random effects linear growth curves.
• Included pubertal status indicators excluding menarche for postmenarcheal females.

Main Results:

• Early pubertal timing was associated with a 22-31% increased odds of dysmenorrhea.
• This association remained significant across varying dysmenorrhea severities (none, mild, severe).

Conclusions:

• Early pubertal timing is a novel and significant predictor of dysmenorrhea risk.
• Assessing pubertal development before menarche can aid in identifying at-risk females.
