Improved estimates of the causes and determinants of
neonatal, child, and adolescent mortality

Improved estimates of the causes and determinants of neonatal, child, and adolescent mortality

Overall Aim

There has been great progress in cause of death estimates within the neonatal and 1-59 month age groups, but for the purpose of better informing policy-makers and program implementers, there is a need to better utilize country data to inform its own estimates and understand these estimates within finer age categorizations. Additionally, the need to understand the mortality patterns of older children and adolescents has come into increasing focus. Lastly, measuring neonatal mortality using survey data also needs to be improved. The project aims to expand upon the progress made during the Maternal and Child Epidemiology Estimation project to enhance the influence of country-specific empirical data on the estimates, establish finer age categorizations in the under-five age group, provide cause of death estimates for older child and adolescent (5-19) age groups, and improve survey based neonatal mortality estimation by better understanding misclassification between neonatal deaths and stillbirths.

Focus Areas

  1. Enhanced compilation, analysis and reporting of all available information on national and global causes of neonatal and child (1-59 months) mortality and among finer age groups
  2. Improved approaches and methods for estimates of subnational causes of child death (in selected countries)
  3. Improved approaches and methods to further unpack mortality burden due to "other" causes of child death
  4. Enhanced compilation, estimation and reporting of all available information on national and global causes of adolescent (5-19 years) mortality
  5. Updated and improved estimation of child (0-4) and adolescent (5-19) etiology of mortality and morbidity of major causes of disease
  6. Improved understanding of the extent of misclassification between stillbirths and neonatal deaths and the contribution of the lack of provider-mother communication on vital status in a mixed method study
