Abstract: |
While maternal and child health statistics in Nigeria are still relatively high, indicators
from several studies show that the southern region has significantly improved over the
northern region. However, the childhood mortality rate in the southern part of the
country is still higher than 70/80 per 1000 live births envisaged by Millennium
Development Goal Four. The contributing factors identified in the literature can be
grouped into endogenous and exogenous variables. The effects of the exogenous
variables are indirect because they operate through the endogenous variables to affect
child’s health. This study examines the interaction effect of endogenous and exogenous
variables in southern Nigeria and its contributions to childhood mortality. Using the
child file from Nigerian Demographic and Health Survey 2008 data, a total weighted
sample of 10,769 births for southern Nigeria were selected for this study. The findings
reveal that there is interaction effect of endogenous and exogenous variables on
childhood mortality in Southern Nigeria. For both urban and rural area, children
under five years with positive indicators have improved chances of survival than those
who have less. Interacting breastfeeding pattern, source of drinking water and toilet
facility with the residential area gave a robust finding, that even when the residential
risk patterns are similar, the risk of childhood mortality in the urban areas is
significantly lower than rural areas.
