Socioeconomic status significantly impacts puberty onset in Turkish girls. Higher socioeconomic status correlates with earlier development of secondary sexual characteristics and menarche.

Area of Science:

  • Pediatrics
  • Human Biology
  • Endocrinology

Background:

  • Puberty onset timing is influenced by various factors, including socioeconomic status.
  • Understanding these influences is crucial for assessing normal development and identifying potential health disparities.

Purpose of the Study:

  • To determine the ages of attainment for successive puberty stages (breast, pubic hair, axillary hair) and menarche in Turkish school girls.
  • To investigate the relationship between socioeconomic status and the timing of pubertal development.

Main Methods:

  • A cross-sectional study involving 1468 Turkish school girls in Istanbul.
  • Subjects were categorized into four distinct socioeconomic classes.
  • Data collected on the ages of onset and progression of secondary sexual characteristics and menarche.

Main Results:

  • Girls in the highest socioeconomic class exhibited earlier onset of secondary sexual characteristics and menarche compared to lower socioeconomic groups.
  • Mean ages for initial breast, pubic hair, and axillary hair development in the highest SES group were 9.8, 10.4, and 10.8 years, respectively.
  • Mean menarcheal age was 12.36 years; later menarche was observed in lower socioeconomic classes.

Conclusions:

  • Socioeconomic status is a significant determinant of pubertal timing in Turkish girls.
  • While pubertal development duration is comparable to European girls, breast development duration is longer.
  • These findings highlight socioeconomic disparities in pubertal development.
