Increased physical education (PE) in schools was linked to reduced adiposity in boys. More weekly PE sessions correlated with smaller waist circumference gains, supporting PE

Area of Science:

  • Public Health
  • Pediatric Obesity Research
  • Adolescent Health

Background:

  • School-based physical education (PE) is a common strategy for preventing adolescent obesity.
  • Previous trials often show non-significant effects of PE on body mass index (BMI).
  • Ecological studies are needed to assess the impact of PE frequency on adiposity.

Purpose of the Study:

  • To investigate the association between the number of weekly physical education sessions and changes in adiposity among adolescents.
  • To analyze the impact of school PE on body mass index (BMI) and waist circumference in secondary school students.

Main Methods:

  • A 5-year longitudinal study involving 2727 adolescents (aged 11-12 at baseline) across 34 London secondary schools.
  • Schools varied in weekly PE sessions: 25 had one, seven had two, and two had three sessions.

  • Annual measurements of weight, height, and waist circumference were used to compare anthropometric changes.

    • Main Results:

    • No significant differences in BMI changes or obesity rates were observed between schools with higher and lower PE frequencies.
    • Unadjusted analyses showed lower waist circumference gains in students from schools with more PE sessions.
    • Boys attending schools with three weekly PE sessions showed approximately 3 cm less waist circumference gain compared to those with one or two sessions (P<0.001).

    Conclusions:

    • Higher frequency of school physical education is associated with reduced gains in adiposity, particularly in boys.
    • Findings support the inclusion of specific recommendations for school PE time in population-level obesity control strategies.
    • Further research may explore gender-specific effects and optimal PE duration for adiposity management.
