Prevalence and trends of overweight and obesity amongst Saudi school children, a study done by using three noninvasive methods.

Prevalence of obesity and over-weight recorded were higher in the boys but the rates recorded by three methods have shown a wide variation. Several factors, such as change in dietary habits, socioeconomic status and the family history of obesity have shown association but physical inactivity and father's obesity were found significant contributory factors. There is an urgent need for intervention to prevent and control obesity and its consequences amongst children in Saudi Arabia.
