Malaria can be fatal during pregnancy, posing a serious risk to both mothers and fetuses, especially in sub-Saharan Africa. Primigravidae are particularly susceptible to placental malaria in areas with high rates of transmission due to insufficient immunity. This study aimed to determine the prevalence of placental malaria infection, risk factors, types of Plasmodium causing malaria during pregnancy, and its relationship with neonatal birth weight among primigravidae.
Methods
This was an analytical cross-sectional study involving 357 primigravidae who delivered at Abubakar Tafawa Balewa University Teaching Hospital, Bauchi, Nigeria. Placental blocks were taken from the pericentric area of the maternal surface of the placenta, and the birth weights of the neonates were recorded. The samples were fixed in 10% neutral-buffered formalin, and histopathological analysis was performed. The primary outcome measure was to determine the relationship between placental malaria and neonatal birth weight. Demographics and outcomes were analyzed using standard statistical tests. Multivariable regression models accounting for potential confounders were created for the primary and secondary outcomes with adjusted odds ratios as the measures of effect.
Results
The prevalence of placental malaria was 38.4%. Among the participants with positive placenta malaria parasitemia, 49.6%, 36.5%, and 13.9% had chronic, acute, and past placental malaria infections, respectively. Only Plasmodium falciparum was found in the placenta. According to the bivariate analysis, unbooked status (p = 0.001), non-use of intermittent preventive therapy for malaria (p
Conclusions
In Nigeria, there is a strong correlation between low birth weight and placental malaria in Primidravidae. Placental malaria was found to be independently correlated with non-uptake of intermittent preventive therapy for malaria.

The study was recently published in the Exploratory Research and Hypothesis in Medicine.
Exploratory Research and Hypothesis in Medicine (ERHM) publishes original exploratory research articles and state-of-the-art reviews that focus on novel findings and the most recent scientific advances that support new hypotheses in medicine. The journal accepts a wide range of topics, including innovative diagnostic and therapeutic modalities as well as insightful theories related to the practice of medicine. The exploratory research published in ERHM does not necessarily need to be comprehensive and conclusive, but the study design must be solid, the methodologies must be reliable, the results must be true, and the hypothesis must be rational and justifiable with evidence.
