Defining childhood obesity is inconsistent globally. A survey of 26 countries reveals varied methods and reference data, hindering international obesity prevalence estimates and comparisons.

Area of Science:

  • Pediatrics
  • Public Health
  • Epidemiology

Background:

  • Defining and measuring childhood obesity is critical for public health initiatives.
  • International comparisons of obesity prevalence are hampered by inconsistent methodologies.

Purpose of the Study:

  • To survey and analyze the methods, cutoff points, and reference materials used for defining childhood and adolescent obesity across 26 countries.
  • To identify inconsistencies in obesity definition practices and their impact on international data comparability.

Main Methods:

  • A survey of information from 26 countries regarding childhood and adolescent obesity definitions.
  • Analysis of frequently used methods like body mass index (BMI) and various cutoff points.
  • Evaluation of reference materials, including national surveys and international data.

Main Results:

  • Body mass index (BMI) was frequently used, alongside other methods, but cutoff points varied considerably.
  • Reference materials were often based on national surveys, with some use of international data; representativeness was frequently insufficient.
  • The collected data was insufficient for meaningful international estimation of obesity prevalence or comparisons.

Conclusions:

  • Significant heterogeneity exists in the definition of childhood and adolescent obesity globally.
  • Current data limitations prevent reliable international prevalence estimates and comparisons.
  • An international consensus, despite inherent uncertainties and compromises, is needed to improve the situation.
