Mortality and health among internally displaced persons in western Kenya following post-election Violence; 2008: novel use of demographic surveillance

ABSTRACT

Objective To evaluate mortality and morbidity among internally displaced persons (IDPs) who relocated in a demographic surveillance system (DSS) area in western Kenya following post-election violence. Methods In 2007; 204 000 individuals lived in the DSS area; where field workers visit households every 4 months to record migrations; births and deaths. We collected data on admissions among children 5 years of age in the district hospital and developed special questionnaires to record information on IDPs. Mortality; migration and hospitalization rates among IDPs and regular DSS residents were compared; and verbal autopsies were performed for deaths. Findings Between December 2007 and May 2008; 16 428 IDPs migrated into the DSS; and over half of them stayed 6 months or longer. In 2008; IDPs aged 15.49 years died at higher rates than regular residents of the DSS (relative risk; RR 1.34; 95confidence interval; CI 1.004.1.80). A greater percentage of deaths from human immunodeficiency virus (HIV) infection occurred among IDPs aged . 5 years (53) than among regular DSS residents (25.29) (P 0.001). Internally displaced children 5 years of age did not die at higher rates than resident children but were hospitalized at higher rates (RR 2.95; 95CI 2.44.3.58). Conclusion HIV-infected internally displaced adults in conflict-ridden parts of Africa are at increased risk of HIV-related death. Relief efforts should extend to IDPs who have relocated outside IDP camps; particularly if afflicted with HIV infection or other chronic conditions
