Distribution de la surmortalité toutes causes en première vague d’épidémie de Covid-19 à l’échelle des intercommunalités franciliennes : quel lien avec les caractéristiques urbaines et sociales des territoires en Ile-de-France ?

Abstract

Since the inception of the COVID-19 pandemic, several studies have highlighted the social and spatial disparities in all-cause excess mortality. In this study, we describe homogeneous territorial groups according to selected multi-dimensional risk factors associated with excess all-cause mortality during the first wave of COVID-19 in the Ile-de-France (Paris) region in France to determine whether these groups have experienced different levels of excess all-cause mortality.We calculated all-cause excess mortality between March 1st and May 31st, 2020, by EPCI/EPT – an intermediate-sized administrative area encompassing several municipalities. We created seven homogeneous territorial clusters of these areas according to selected contextual, demographic, social and initial population health status variables. We analysed the levels of all-cause excess mortality between the clusters, in the general population and for the 50-74 yrs and 75+ yrs age groups.Overall all-cause excess mortality for the region was +61.8%. It was higher in the 75+ yrs (+72.1%) than in the 50-74 yrs age group (+49.7%). All-cause excess mortality varied significantly across the seven clusters of our typology, both overall (Kruskal-Wallis (KW) Chi² = 30,93, p
