Background

Monitoring of overweight and obesity among children; by using different growth charts; is fundamental to disease prevention and health promotion.
Aim of the study

To determine overweight and obesity for age among primary school children in Upper Egypt using the Egyptian and CDC growth charts.
Subjects and methods
