Abstract
This thesis focuses on the determinants of infant and child mortality in Lesotho.
It specifically examines how infant and child mortality is related to environmen-
tal, demographic and socio-economic factors. A survival analysis approach is
used to analyze the determinants of child mortality. Duration or time-to-event
models are easily applicable to the problem of child mortality as this class of
models is able to account for problems like right-censoring, structural model-
ing and time varying covariates which other classes of models, such as logistic
regression, cannot handle adequately. In this application the age at the child's
death is used as the time to event.
Household, environmental, demographic and socio-economic factors are found to
have significant impact on child mortality. Policies aimed at achieving the goal
of reduced child mortality should be directed on improving the households en-
vironmental and / or socio-economic status of a child for this goal to be realized.
Keywords: child mortality, infant mortality, neonatal mortality, duration model,
survival analysis, failure function, hazard rate.
