Relations spatiales entre les caracteristiques des territoires et les taux d'enfants de groupes ethnoculturels signales a la protection de la jeunesse

OBJECTIVES: The objectives of this study were to 1) map the geographic distribution of rates of children reported to Montreal child protective services by ethnocultural group (Black, other visible minorities, not from visible minorities) and 2) estimate the relative contribution of different territorial characteristics to the rates for those groups. METHOD: The study covered the 505 Montreal-area census tracts for which complete data were available. The reporting rates by group (dependent variables) and various territorial characteristics such as poverty (independent variables) were mapped and subjected to multiple linear regression and geographically weighted regression. The results of the geographically weighted regression were then mapped. RESULTS: The geographic distribution and reporting rates varied greatly by group, with the Black children having the highest rates. Although territorial characteristics explained 51% of variance for the children who were not members of visible minorities, they were clearly less effective in predicting rates in the case of Black children (18%) and other minorities (18%). CONCLUSION: Already well-known territorial risk factors are at work in Montreal, but their influence is not equally strong in all census tracts nor, especially, in all ethnocultural groups. Therefore, when only the distribution and prediction of reports for all children as a whole are examined, important differences are underestimated. Access to and appropriateness of services offered to vulnerable families, including those of visible minorities, could, however, be improved with a better understanding of local dynamics. KEY WORDS: Child abuse; domestic violence; geographic mapping; risk factors; epidemiology OBJECTIFS: Les objectifs de cette etude etaient de 1) cartographier la distribution spatiale des taux d'enfants de groupes ethnoculturels signales a la protection de la jeunesse (enfants noirs, d'autres minorites visibles et non issus des minorites visibles) et 2) estimer la contribution relative de diverses caracteristiques territoriales a ces taux selon les groupes. METHODE: Cinq cent cinq secteurs de recensement montrealais sont etudies. Les taux d'enfants signales selon les groupes (variables dependantes) et des caracteristiques territoriales comme la pauvrete (variables independantes) sont cartographies puis soumis a des regressions lineaires multiples et geographiquement ponderes (GWR); des resultats GWR sont finalement cartographies.
