Abstract

Les enfants jumeaux comparativement aux singletons sont sujets à une mortalité plus élevée. Cette situation est d'autant plus préoccupante dans les pays d'Afrique subsaharienne, où la mortalité est déjà plus élevée que partout ailleurs dans le monde. Cela fait de la santé des jumeaux un défi supplémentaire de santé publique sur ce continent. Dans ce travail, nous apportons une contribution complémentaire à toutes celles qui existent déjà, mais en mobilisant d'autres types de données moins utilisées pour analyser la surmortalité des jumeaux : des données longitudinales provenant de 21 observatoires de population. Il compare les courbes de survie entre jumeaux et singletons sur la période 2010-2014, présente l'évolution dans le temps (de 1995 à 2014) de ces courbes et détermine l'âge auquel une différence de taux de mortalité entre jumeaux et singletons serait maintenue. Il étudie également les facteurs associés à la différence de survie entre les jumeaux et les singletons de moins de 5 ans. Les résultats obtenus montrent l'existence de disparités significatives entre les observatoires de population en termes de différentiel de survie entre jumeaux et singletons. Ils montrent également que le différentiel de survie entre jumeaux et singletons se réduit avec le temps. Nos analyses ont également montré qu'il n'y aurait pratiquement plus de surmortalité des jumeaux après l'âge de 5 ans. En outre, l'analyse des facteurs associés au différentiel de survie entre jumeaux et singletons a montré que les facteurs biomédicaux (en particulier le faible poids à la naissance et la prématurité) expliquent la majeure partie de ce différentiel.
