Evaluation of melatonin on the precocious puberty: a pilot study

Area of Science:

• Endocrinology
• Sleep Medicine
• Pediatrics

Background:

• Precocious puberty is a condition characterized by early onset of pubertal development.
• Melatonin, a hormone regulating sleep-wake cycles, has been implicated in pubertal development.
• The relationship between melatonin levels and sleep quality in girls with precocious puberty requires further investigation.

Purpose of the Study:

• To evaluate the effect of 6-sulphatoxymelatonin on the sleep quality of girls with precocious puberty.
• To compare melatonin levels and sleep patterns in girls with precocious puberty, normal prepubescence, and normal puberty.

Main Methods:

• A study involving 99 girls divided into three groups: precocious puberty, normal prepubescence, and normal puberty.
• Data collection included demographic and clinical information, hormonal evaluation for 6-sulphatoxymelatonin, and the modified Rush Sleep Diary for sleep quality assessment.

Main Results:

• Girls with true precocious puberty had the lowest levels of 6-sulphatoxymelatonin (37.04 ± 5.47 ng/ml) compared to those with normal prepubescence (75.23 ± 10.84 ng/ml) and normal puberty (45.66 ± 3.87 ng/ml).
• The group without pubertal development experienced more daytime sleep than the other groups.
• A statistically significant difference (p < 0.001) was observed in 6-sulphatoxymelatonin levels between the groups.

Conclusions:

• Melatonin may play a role in the process of precocious puberty, despite the observed sleep data.
• Lower melatonin levels in girls with precocious puberty warrant further research into its etiological contribution.
