Geographic coverage of demographic surveillance systems for characterising the drivers of childhood mortality in sub-Saharan Africa

摘要: A major focus of international health and development goals is the reduction mortality rates in children under 5 years age. Achieving this requires understanding drivers how they vary geographically to facilitate targeting prioritisation appropriate interventions. Much our knowledge on causes of, trends in, childhood come from longitudinal demographic surveillance sites, with a renewed recently establishment growth networks sites which standardised outputs can broader processes. To ensure that collective be used derive comprehensive monitoring system for driving policy tackling mortality, confidence needed existing planned are providing reliable representative picture geographical variation factors associated mortality. Here, we assembled subnational data as well key known it household surveys 27 sub-Saharan African countries. We then mapped locations assess extent current coverage range factors, identifying where gaps exist. The results highlight regions unique combinations poorly represented by distribution such southern Mali, central Nigeria Zambia. Finally, determined new systems could improve coverage.
