Impact of being born small for gestational age on onset and progression of puberty

Area of Science:

• Pediatrics
• Endocrinology
• Growth and Development

Background:

• Children born small for gestational age (SGA) exhibit increased risks for perinatal complications and later chronic diseases.
• Prenatal growth is increasingly linked to pubertal development, yet research on SGA children is limited and methodologically diverse.
• Existing studies show boys born SGA often achieve normal pubertal timing but may have reduced adult height.

Purpose of the Study:

• To review and discuss factors influencing pubertal development in children born small for gestational age (SGA).
• To synthesize current knowledge on the timing, duration, and progression of puberty in SGA populations.
• To highlight the challenges in comparing existing research due to methodological variations.

Main Methods:

• Literature review of studies investigating pubertal development in children born small for gestational age (SGA).
• Analysis of reported data on pubertal timing, progression, and final height in SGA cohorts.
• Discussion of influencing factors, including intrauterine growth retardation and potential hormonal or genetic elements.

Main Results:

• Boys born SGA typically experience normal pubertal timing but may not reach their target adult height.
• Girls born SGA often show a correlation between intrauterine growth restriction and either earlier or normal pubertal timing with accelerated progression.
• Significant heterogeneity exists in reported outcomes, complicating direct comparisons.

Conclusions:

• Pubertal development in children born SGA is complex and influenced by multiple factors.
• Further standardized research is needed to clarify pubertal trajectories and optimize management for SGA individuals.
• Understanding these patterns is crucial for addressing long-term health outcomes in this population.
