Kozuki, N., E. Sonneveldt, and N. Walker, Residual confounding explains the association between high parity and child mortality, BMC Public Health., 2013. 13 Suppl 3: p. S7.
Background: This study used data from recent Demographic and Health Surveys (DHS) to examine the impact of high parity on under-five and neonatal mortality. The analyses used various techniques to attempt eliminating selection issues, including stratification of analyses by mothers’ completed fertility. Using these techniques these analyses find compelling evidence that the excess risk of mortality often ascribed to higher parity births in fact is linked to differences between women who have higher fertility.
