Socioeconomic determinants and maternal malaria: impact on neonatal parasitemia in Osun State, Southwest, Nigeria

Abstract

BACKGROUND: Maternal malaria and its sequelae, including maternal mortality and neonatal infection, represent a growing public health crisis in Sub-Saharan Africa, often exacerbated by underlying socioeconomic factors. The study seeks to assess the associations between maternal socioeconomic indicators, maternal malaria, and neonatal peripheral parasitaemia in a Nigerian hospital. METHODS: A cross-sectional analysis of 85 mother-infant pairs was conducted at a hospital in Osogbo, Osun state, Nigeria. Well-structured questionnaires were used to collect maternal demographics, socioeconomic indicators, and preventive practices. Mother, cord blood, and neonatal peripheral blood samples were collected for parasitemia through microscopy. Descriptive statistics, Fisher exact and chi-square tests were used for categorical variables, and univariate logistic regression for continuous predictors. RESULTS: The prevalence of neonatal peripheral parasitemia was 8.2% (7/85). Maternal parasitemia strongly predicted neonatal infection. All positive neonates were born to mothers with positive microscopy (7/19), whereas no neonates from parasitemia negative mothers were infected (p < 0.001). No statistically significant associations were found between neonatal parasitemia and maternal education (p = 0.912), occupation (p = 0.183), insecticide treated net use (p = 0.413), or intermittent preventive therapy uptake (p = 1.000). CONCLUSIONS: The present study revealed maternal parasitemia as a primary risk factor for neonatal malaria. While socioeconomic factors showed no significant association in this small cohort, these preliminary findings highlighted the need for larger studies with refined socioeconomic measures to fully elucidate these relationships. This highlights the critical need for strengthening antenatal malaria screening, ensuring timely treatment of maternal infection, and enhancing community-based malaria education to reduce vertical transmission in high-burden regions like Osun State, Nigeria.
