Diabetes mellitus and its effects on menarche

Area of Science:

• Pediatric Endocrinology
• Reproductive Health
• Metabolic Disorders

Background:

• Menarcheal age is a key indicator of pubertal development.
• Diabetes mellitus can potentially impact hormonal regulation and pubertal timing.

Purpose of the Study:

• To investigate the relationship between diabetes mellitus onset and the age of menarche in girls.
• To determine if the timing of diabetes onset influences pubertal maturation.

Main Methods:

• A combined mail and medical record survey was conducted.
• Participants included non-diabetic girls and diabetic girls aged 9 years and older.
• Diabetic girls were categorized by diabetes onset relative to age 11 years.

Main Results:

• Mean age of menarche was 13.0 years in controls and 13.4 years in diabetics.
• Diabetic girls with onset after age 11 had a significantly later mean menarcheal age (14.0 years) compared to those with onset before age 11 (13.1 years) and controls (p < 0.005).
• Diabetes onset around puberty onset showed a more disruptive effect on hypothalamic-pituitary-gonadal axis maturation.

Conclusions:

• The timing of diabetes onset, particularly around puberty, significantly affects menarcheal age.
• Prepubertal diabetes onset appears to have less impact on pubertal maturation compared to onset near puberty.
• These findings highlight the importance of considering diabetes onset timing in assessing pubertal development in girls.
