Health effects of single motherhood on children in sub-Saharan Africa: a cross-sectional study

Although progress has been made toward reducing child morbidity and mortality globally, a large proportion of children in sub-Saharan Africa still die before age five and many suffer chronic malnutrition. This study investigated the influence of single motherhood on stunting and under-5 mortality in Cameroon, Nigeria and Democratic Republic of the Congo (DRC). Particular attention was paid to the influence of mother's economic resources, parental care and health behaviour on the difference in children's health in single and two-parent families. Data were obtained from most recent Demographic and Health Surveys in Cameroon (2011), Nigeria (2008) and DRC (2007). The sample included women aged 15-49 years old and their under-5 children 11,748 in Cameroon, 28,100 in Nigeria, and 8,999 in DRC. Logistic regression and Cox proportional hazard analysis were used to estimate stunting and under-5 mortality, respectively. The result showed that compared with children whose mothers were in union, children of single mothers who were not widows were more likely to be stunted (OR 1.79 p
