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.

Résumé

Objectif: L’obésité infantile est une préoccupation de santé publique au Canada. Peu de données anthropométriques ont été publiées pour refléter la prévalence de l’obésité chez les enfants canadiens. Cet article traite de la prévalence de l’obésité chez des élèves de 11 écoles de London, Ontario.
Méthodes: Les données sur le poids et la taille ont été recueillies à l’aide de méthodes normalisées. Les tables d’indices de masse corporelle (IMC) selon l’âge établies par les Centers for Disease Control and Prevention des États-Unis (CDC) et la table internationale de Cole ont été utilisées pour classer les enfants par catégories de poids.
Résultats: L’échantillon était composé de 1 570 écoliers de 6 à 13 ans. Selon les tables d’IMC des CDC, 16,6% et 11,8% des enfants présentaient un excès de poids et de l’obésité, respectivement. En comparaison, la table de Cole donnait 17,5% et 7,6% des enfants comme présentant un excès de poids et de l’obésité, respectivement.
Conclusions: L’excès de poids est très répandu dans la population étudiée. Des interventions de santé publique sont justifiées pour enrayer l’épidémie d’obésité chez les enfants d’âge scolaire.
