Socio-demographic determinants of post-caesarean neonatal mortality in Nigeria

Neonatal mortality remains a major health concern in sub-Saharan Africa. We conducted a cross-sectional, population-based, retrospective analysis of 31,828 births between 2009 and 2013 to explore the relationship between socio-demographic variables and post-caesarean neonatal mortality in Nigeria. We calculated the caesarean section (CS) rates, the odds of having a CS and post-CS neonatal mortality within variable subgroups. The national average CS rate was 2.1%. The CS rate increased with the increasing wealth index, educational attainment, maternal age, higher among urban residents and among those from the Southern part of Nigeria. The odds of experiencing post-CS neonatal mortality was significantly higher in the Northern regions (OR 2.51-3.17) among rural residents (OR 2.63), economically poorer groups (OR 3.68), with no formal education (OR 3.01) and older maternal age groups (OR 1.76-2.0). Efforts to increase the rate and quality of peripartum services delivered to pregnant women are needed among both advantaged and disadvantaged groups.Impact statementWhat is already known on this subject? In sub-Saharan Africa, a caesarean section is a lifesaving procedure for both the women and their unborn babies. The neonatal mortalities that occur following the procedure need to be explored and quantified.What do the results of this study add? Socioeconomic differentials exist in the access to a caesarean section. However, these differentials have a limited influence on neonatal mortality post-caesarean section in Nigeria.What are the implications of these findings for clinical practice and/or further research? While socio-demographic variables influence access to health care services, timeliness and quality of care are factors to be considered in ensuring societies get the benefits of caesarean section as a lifesaving procedure.
