The Effects of Maternal Mortality on Infant and Child Survival in Rural Tanzania: A Cohort Study.

Objectives: The full impact of a maternal death includes consequences faced by orphaned children. This analysis adds evidence to a literature on the magnitude of the association between a woman's death during or shortly after childbirth, and survival outcomes for her children.

Methods: The Ifakara and Rufiji Health and Demographic Surveillance Sites in rural Tanzania conduct longitudinal, frequent data collection of key demographic events at the household level. Using a subset of the data from these sites (1996-2012), this survival analysis compared outcomes for children who experienced a maternal death (42 and 365 days definitions) during or near birth to those children whose mothers survived.

Results: There were 111 maternal deaths (or 229 late maternal deaths) during the study period, and 46.28 % of the index children also subsequently died (40.73 % of children in the late maternal death group) before their tenth birthday-a much higher prevalence of child mortality than in the population of children whose mothers survived (7.88 %, p value <0.001). Children orphaned by early maternal deaths had a 51.54 % chance of surviving to their first birthday, compared to a 94.42 % probability for children of surviving mothers. A significant, but lesser, child survival effect was also found for paternal deaths in this study period.

Conclusions: The death of a mother compromises the survival of index children. Reducing maternal mortality through improved health care-especially provision of high-quality skilled birth attendance, emergency obstetric services and neonatal care-will also help save children's lives.
