Objective:
To develop an internationally acceptable
definition of child overweight and obesity, specifying the measurement,
the reference population, and the age and sex specific cut off points.
Design:
International survey of six large nationally representative cross sectional growth studies.
Setting:
Brazil, Great Britain, Hong Kong, the
Netherlands, Singapore, and the United States.
Subjects:
97 876 males and 94 851 females from birth to 25 years of age.
Main outcome measure:
Body mass index
(weight/height2).
Results:
For each of the surveys, centile curves were drawn that at age 18 years passed through the widely used cut off
points of 25 and 30 kg/m2 for adult overweight and obesity.
The resulting curves were averaged to provide age and sex specific cut
off points from 2-18 years.
Conclusions:
The proposed cut off points, which are
less arbitrary and more internationally based than current
alternatives, should help to provide internationally comparable
prevalence rates of overweight and obesity in children.
