In this study we analyze thedmographic and geographical distribution ofpedestrian accidents (n=28,452) in the QuebecMunicipalitD rkgionales de comt6 (MRC) reported between January 1, 1983 and December 31, 1988. In order to be able to make comparisons between MRCs. we have created in Comparative Mortality Index and a Comparative Morbidity Index. We use a logistic regression model to single out explanatoxy factors. The main tendencies which are apparent in the demographic analysis are an overrepresentation of young persons and elderly persons in the accident statistics, and that men are more at risk than women. Men 15 years and under and men 65 years and over are more at risk of being involved in afatalpedestrian accident. The geographic analysis show that among men, the average mortality rate is one and a half times greater in rural MRCs than inurbanMRCs; among women, rural mortality is two and a half times greater thanurbanmortality. In the case of non-severe injuries we note an over-representation of urban MRCs. Young persons 15 years or less who live in an urban, populated zone are those most at risk of being involved in a pedestrian accident. Identifying high risk groups or areas is a prerequisite step for irjury prevention and control.Injuries of pedestrians in automobile-related accidents constitute a serious problem. Pedestrian deaths make up the second-largest category of deaths due to traffic accidents. Over the past 10 years in Quebec, Marie-France Joly is on the faculty

Par le truchement d'analyses quantitatives et cartographiques, l'article étudie les rapports entre la répartition spatiale de la morbidité hospitalière dans l'île de Montréal et certaines variables géographiques, démographiques et socio-économiques. Dans la majorité des cas, un indice socio-économique émerge comme principal facteur explicatif. Pour ce qui est de la localisation des troubles mentaux toutefois, la densité de population et l'accessibilité au réseau hospitalier paraissent être des variables importantes. Par ailleurs, un facteur de mobilité géographique peut expliquer, dans une certaine mesure, l'aggravation des complications reliées à la grossesse et à l'accouchement.
