*
Values presented are percentages of weight estimates within specified limits of deviation (≤10 and ≤20 %) from actual weight.
†
Underweight/normal and overweight/obese were defined as <85th percentile and ≥85th percentile for weight-for-length among infants aged <2 years and for BMI-for-age among children aged 2–5·9 years, respectively.
