Abstract
Purpose: Childhood obesity is a public health concern in Canada. Few published anthropometric data are available to indicate obesity prevalence in Canadian children. Obesity prevalence is reported for school-aged children in 11 London, Ontario, schools. Methods: Data on body weight and height were obtained using standardized procedures. United States Centers for Disease Control and Prevention (CDC) body mass index (BMI)-for-age references and Cole’s international BMI reference were used to classify the children’s weight categories. Results: The study included 1,570 pupils aged six to 13. The CDC BMI references categorized 16.6% and 11.8% of children as overweight and obese, respectively. In comparison, when the Cole BMI reference and cut-off points were used, 17.5% and 7.6% of children were classified as overweight and obese, respectively. Conclusion: Overweight is prevalent in the study population. Public health interventions are warranted to curb the obesity epidemic in school-aged children.
