Chronic sleep curtailment from infancy to school age is linked to increased childhood adiposity. Reduced sleep duration in early life is associated with higher body mass and central fat accumulation by mid-childhood.

Area of Science:

  • Pediatric Health
  • Sleep Science
  • Obesity Research

Background:

  • Adequate sleep is crucial for child development.
  • Chronic sleep curtailment may impact metabolic health.
  • Understanding early life sleep patterns' long-term effects is important.

Purpose of the Study:

  • To investigate the association between chronic sleep curtailment from infancy to mid-childhood and adiposity.
  • To determine if reduced sleep duration in early life relates to total and central body fat in children.

Main Methods:

  • Prospective cohort study of 1046 children.
  • Sleep duration reported by mothers from 6 months to 7 years.
  • Adiposity measured by BMI z-score, fat mass index, and waist/hip circumference.

Main Results:

  • Children with the most sleep curtailment (score 0-4) had higher BMI z-scores (0.48 U increase).
  • Similar associations were found for total and trunk fat mass index and waist/hip circumferences.
  • Higher odds of obesity were observed in children with significant sleep curtailment.

Conclusions:

  • Chronic sleep curtailment during infancy and childhood is associated with increased overall adiposity.
  • Reduced sleep duration in early life is linked to greater central adiposity in mid-childhood.
