HKOS Paediatric Consensus Statements
This survey is to assess the level of agreement among the author group with the proposed statements. These statements have been drafted by the paediatric committee members and have already received one round of voting at a consensus meeting earlier this year.
The survey will rate your agreement with each recommendation 5-point Likert scale (i.e., Accept completely; Accept with some reservation; Accept with major reservation; Reject with reservation; Reject completely). Agreement by 75% of total voting group members is defined as the threshold for acceptance of a statement.

Statement 1: 0–2 years.
• Option 1: BMI-for-age is recommended for use to assess overweight and obesity in children. However, there is a lack of evidence to define excess adiposity in children 0–2 years. As a practical approach, we recommend using the HKGS 2020 and WHO 2006 standards as guidance points for additional monitoring/investigation.
• Option 2: BMI-for-age is recommended for use to assess overweight and obesity in children, however, there is a lack of evidence to define excess adiposity in children 0-2 years and we, therefore, are unable to derive a recommendation.
WHO 2006
HKGS 2020
Overweight
BMI-for-age >2 SD above the growth standard median
99.6th centile (2.67 SD) ≥ BMI > 98th centile (2.01 SD)
Obese
BMI-for-age >3 SD above the growth standard median
> 99.6th centile (2.67 SD)
Statement 2: 2–5 years
We suggest using the new BMI centile chart from the 2020 Hong Kong Growth Study for children aged 2–5 years, with overweight defined as 99.6th centile ≥ BMI > 98th centile and obesity as >99.6th centile
Statement 3: 5–18 years
We suggest using the new BMI centile chart from the 2020 Hong Kong Growth Study for children aged >5 to <18 years, with overweight defined as 98th centile ≥ BMI > 91st centile and obesity as >98th centile for age and sex.
98th centile (2.01 SD) ≥ BMI > 91st centile (1.33 SD)
> 98th centile (2.01 SD)
Statement 4: Other anthropometric measures
We suggest using other anthropometric measures such as waist circumference (WC) and waist-to-height ratio (WHtR) in children as adjuncts to the BMI to evaluate adiposity-related disease risk
Subtext: BMI is the standard method for screening and other anthropometric measures e.g., WC/WHR/WHtR can be used to supplement BMI because they measure central/abdominal obesity, which is linked to high risk of cardiovascular disease Please indicate your level of agreement with the above statement:
