Changes in prevalence of childhood overweight over time in selected countries

For this figure, the prevalence of overweight children is defined as the percent of children with body mass index (BMI) ≥85th percentile, using the standards from the International Obesity Task Force (IOTF). The countries are selected on the appropriateness and availability of the data. The surveys are not strictly comparable because of differences in age range and methodology. With the limited data available, prevalences are not age-standardized.
