Risk Factors for Child Mortality in Northern Ghana: A Case-Control Study

Abstract

Background. A population-based case-control study was carried out to investigate potential risk factors for post-neonatal and child mortality in northern Ghana where child survival rates are among the lowest in Africa. Method. Cases were post-neonatal infant and child deaths identified within a large population under continuous demographic surveillance. For each case, one living control, matched for age, sex and locality, was selected from the demographic database. Mothers of each case and control were interviewed to obtain Information on social, economic, demographic, environmental and other possible risk factors. Matched analyses of the 317 cases and their controls were performed using discordant pairs analysis and conditional logistic regression. Results. The mortality rate for children aged 6 months to 4 years was estimated as 23.9/1000 children/year. An increased risk of death was observed where the delivery was not performed by a trained person (OR = 1.8, 95% CI: 1.0–3.2), if the preceding birth interval was Conclusions. Few strong risk factors for mortality were identified, perhaps because living conditions within the study population are relatively homogeneous. While mortality rates may be reduced by targeted interventions, such as increasing deliveries by trained people, more general improvements in the socioeconomic status in the region are essential.
