international than others, and should encourage direct comparison of
trends in child obesity worldwide.
Unfortunately, the authors did not provide definition for
underweight, which is still very important public health problem
especially in many low income countries. As the IOTF definition is more
international and encouraging researchers like me to adopt these new
categories, it will be very useful if they could provide additional
definition for underweight, which might help in assessing and addressing
the underweight problem as well as overweight and obesity problem. This
will also help researchers to be more consistent rather than using this
new definition for overweight and obesity, and the old definition for
