Les determinants de la sante des personnes exposees a des crises majeures. Le cas des deplaces internes au Burundi.

摘要

INTRODUCTION Collective violence in the form of civil war and other violent political conflict places a heavy burden on public health. More than half of all deaths caused by conflicts around the globe occur in Africa. One of the consequences of such conflict is the massive displacement of populations seeking refuge either outside their country or, increasingly, within their country's borders. Those who remain within their country are called internally displaced persons. Although little documented, the health of these people is every bit as vulnerable as that of refugees. From 1993 to 2005, Burundi was plunged into a socio-political crisis of unprecedented proportions. In 2001, approximately 10% of the population was living in displaced person camps.;OBJECTIVE To document the health status of persons displaced by the war in Burundi and identify its determinants.;CONCEPTUAL FRAMEWORK The conceptual framework is based on a modelling of the association between traumatic events, factors in the post-trauma environment and the health status of internally displaced Burundians.;METHOD This cross-sectional study was carried out in two displaced persons camps in Burundi. It uses retrospective data on exposure to traumatic events and cross-sectional data on health status and factors in the post-trauma environment. Using a short scale especially designed for this study, the participants answered questions about the traumatic events that they or those close to them had experienced. Factors in the post-trauma environment were also documented. To measure health status, a questionnaire containing some of the 17 items of the Duke Health Profile was used. Two translations were made, and several of the items were adapted to the particular context.;RESULTS The traumatic events experienced by displaced persons in Burundi are negatively associated with physical health, social health and perceived health, and positively associated with disability. A number of factors in the post-trauma environment were also associated with health status. However, some of these associations are difficult to interpret because of their interactions with traumatic events. These interactions sometimes act as effect modifiers by diminishing or amplifying the initial association between certain traumatic events and the health status of displaced persons.;CONCLUSION The results reveal a differential response associated with, on the one hand, previously experienced traumatic events and, on the other hand, the post-trauma environment in interaction with these traumatic events. This thesis concludes that factors in the post-trauma environment constitute important determinants of the health of persons displaced by war.;Keywords: Civil war, internally displaced persons, refugees, collective violence, post-trauma environment, post-traumatic stress, health status, Duke Health Profile, Burundi
