How accurately can you screen for risk of overweight in children by looking?

It has been said that "few medical conditions can be diagnosed as confidently by untrained individuals as gross obesity." Yet it is very difficult to distinguish children who are at risk of overweight from normal children. In childhood, the distinction is made more difficult by age-related physiological variations (Poskitt, 1995).

Take a look at three photos of preschool aged children to see how accurately you can screen for risk of overweight in children solely by looking at them. We want you to try to identify children with a BMI-for-age equal to or greater than the 85th percentile and less than the 95th percentile.
