Prevalence calculated using SPART criteria (BMI ≥ P85 and <P97). Prevalence calculated using IOTF reference values (cut-off points corresponding to an adult BMI ≥ 25 and <30 kg/m2). Prevalence calculated with WHO growth standards (BMI ≥ 1 SD and <2 SD). McNemar test for comparison of prevalence of overweight returned using the SPART and WHO criteria. McNemar test for comparison of prevalence of overweight returned using IOTF and WHO criteria. McNemar test for comparison of prevalence of overweight returned using the SPART and IOTF criteria.
