| Abstract | Child health remains a priority area for health policy in sub-Saharan Africa. Disparities in child mortality between and within countries have persisted and widened considerably during the last few decades. While researchers have devoted considerable attention to the impact of individual-level factors on child mortality, less is known about how community characteristics and institutions affect health outcomes for children, even though they have a prominent role in theoretical models. The aim of this thesis is to identify individual and contextual effects of child mortality by using data from the latest round of Demographic Health Surveys for all countries in sub-Saharan Africa. Two sets of questions are addressed in this research.First, we evaluate the impact of contextual factors on the risk of dying before age 5 net of the effect of individual factors. The results indicate that some attributes of the community influence the mortality risks of children, over and above the intermediate factors included in this investigation. For instance, in half of the countries under study a 1% increase in the proportion of children fully immunized in the community is associated with a decrease of 17-79% in the odds of dying before age 5. The proportion of women in the community completing secondary school also significantly increases child survival. This effect is, in some countries, in addition to the positive individual-level effect of the child’s own mother being educated. Net of individual and household characteristics, higher community-level ethnic homogeneity is associated with decreased odds of dying before age 5 in some countries. Overall, the results of this study therefore suggest that the challenge to reduce under-five mortality goes beyond addressing individual factors, and requires a better understanding of contextual factors. Second, the study exploits recent national survey data for nine countries in sub-Saharan Africa to investigate the association of LBW and mortality not only in infancy but also during childhood, using a standardized methodology to adjust missing birth weight data from household surveys while accounting for unobserved family-level factors (genetic or behavioral) that may modify the relationship between birth weight and under-five-years mortality. We find evidence of the impact of birth weight on the risk of dying not only in infancy but also during childhood, which remains strong and significant in all countries even after controlling for potential confounding factors. The main policy implication of our findings is that reducing the incidence of LBW may be an important prevention strategy to combating child mortality in sub-Saharan Africa countries. |
