Early Menstruation Linked to Dramatic Height Differences in Girls

A Swedish study following nearly 800 women from birth to adulthood discovered that girls who experience their first period early grow around 13 centimeters taller, contrasting sharply with those who start menstruation later, who only grow around 3 centimeters. The findings reveal significant variations in post-menarche growth, challenging longstanding beliefs about height development after menstruation.

In a groundbreaking study tracking nearly 800 Swedish women from birth to adulthood, researchers have discovered significant height differences linked to the timing of the first menstrual period.

The University of Gothenburg study found girls who experience menarche at or before 12 years of age grow taller by approximately 13 centimeters, compared to just 3 centimeters for those starting at or over 14. This discovery debunks the widespread belief that girls typically grow only 6-8 centimeters after their first period.

Early menstruation is also inversely related to childhood BMI, with a higher BMI indicating an earlier menarche, which might be connected to obesity and heart disease risks in adulthood.
