Abstract
Objectives: 1) To determine caries risk factors in second and sixth grade Quebec children; 2) To test multivariate models which identify children as belonging to a high prevalence group.
Methods: For the 1989–90 Santé Dentaire Québec survey, 2,291 second grade and 2,111 sixth grade school children responded to a questionnaire on their personal habits of hygiene and diet and underwent a clinical examination, while their parents answered a questionnaire regarding their family’s socioeconomic status.
Results: Statistics demonstrate a stronger link between socioeconomic variables and caries prevalence than demographic and sanitary factors. Children emerging from a high socioeconomic milieu have better dental health than children with low socioeconomic standing. The most effective model, however, registers a sensitivity of 65% and a specificity of 66%, revealing the inadequacy of statistical models to accurately identify children in the caries high prevalence group.
Résumé
Objectifs: 1) Identifier les facteurs qui caractérisent les groupes vulnérables à la carie dentaire dans la population scolaire du Québec de deuxième et sixième année; 2) Tester des modèles multivariés qui déterminent l’appartenance des écoliers à un groupe avec prévalence élevée.
Méthodes: Dans le cadre de l’enquête Santé Dentaire Québec de 1989–90, 2 291 enfants de deuxième année et 2 111 de sixième année ont été examinés cliniquement et ont répondu à un questionnaire portant sur leurs habitudes d’hygiène et leur alimentation. Parallèlement, leurs parents recevaient à domicile un questionnaire sur les caractéristiques socio-économiques de leur famille.
Résultats: Les variables socio-économiques présentent de plus forts liens statistiques avec la prévalence de la carie que les variables démographiques et sanitaires. Plus l’enfant appartient à une classe sociale élevée, meilleure est sa santé dentaire. Les modèles statistiques d’identification s’avèrent toutefois insuffisants pour identifier les écoliers vulnérables puisque, pour le modèle retenu, la sensibilité atteint 65 % et la spécificité 66 %.
