Early-Life Risks of Central Precocious Puberty

Area of Science:

• Pediatric Endocrinology
• Reproductive Health
• Public Health

Background:

• Central precocious puberty (CPP) is a condition where puberty begins unusually early.
• Identifying early-life risk factors for CPP is crucial for timely intervention and understanding pubertal development.
• Previous research has explored various environmental and maternal factors, but comprehensive analysis is ongoing.

Purpose of the Study:

• To investigate the associations between early-life factors and the risk of developing central precocious puberty (CPP).
• To analyze the impact of maternal gestational weight gain (GWG), gestational diabetes mellitus (GDM), and exclusive breastfeeding on CPP incidence.
• To explore potential gender-specific effects of these risk factors on CPP development.

Main Methods:

• Utilized data from the Taiwan Puberty Longitudinal Study, encompassing 2241 children.
• Collected information on risk factors through questionnaires and pubertal assessments.
• Employed Generalized Linear Models in R for statistical analysis of associations.

Main Results:

• Higher gestational weight gain (GWG) was associated with an increased overall risk of CPP (OR: 1.03).
• Maternal gestational diabetes mellitus (GDM) significantly increased CPP risk, particularly in males (OR: 2.66).
• Longer exclusive breastfeeding duration showed a trend towards lower CPP risk (OR: 0.96), though not statistically significant by gender.

Conclusions:

• Maternal GWG is linked to increased CPP risk overall, but acts protectively in females.
• Maternal GDM is a significant risk factor for CPP, especially in males.
• Exclusive breastfeeding duration shows an inverse correlation with CPP risk, warranting further investigation into gender-specific effects.
