“…This study is in consonance with Previous Studies that have demonstrated the relationship between placental malaria and parity and have reported the prevalence to be higher in primigravidas than multigravidas, and in these studies, results are controlled for age [22][23][24][25].…”

Introduction: In Malaria endemic countries, gestational and cord blood malaria prevalence are highly variable. A comprehensive study to determine the prevalence of placental and cord malaria has not been undertaken in Imo state, south eastern Nigeria. Thus, the need to determine prevalence of placenta and chord blood with Plasmodium falciparum infection among pregnant mothers and their neonates in Federal university teaching hospital Owerri, Imo State, Nigeria. Methodology: A hospital based cross sectional study was carried out between the months of July 2021 and June, 2022 in some public and private hospitals in Owerri, south eastern Nigeria. Malaria transmission is stable with a high seasonal transmission from July to October. Placental and umbilical cord blood was collected into an EDTA bottle from mothers who consented and their neonates respectively at delivery. The presence of Plasmodium speciewas assessed microscopically and quantified by WHO Certified Malaria Microscopists. Parasite density was determined using WHO malaria microscopy protocol. Malaria parasite density was grouped as 1-500parasites/µl, 501-5,000parasites/µl (low), 5,001–10,000 parasites/µl (high), and >10,000 parasites/µl (very high) respectively for ease of analysis. Data was analyzed considering the parasite density grouping and parity while placenta and cord malaria prevalence were determined. Results: Placental and congenital malaria prevalence by microscopy was 21.3% vs. 8.2%. The primigravid had the highest infection rate of 33.0%. Considering the relationship between infection prevalence and parity of pregnancy, there was a significant difference P=.001. 4.2% of 119 neonate and 13.6% of 88 neonates from multigravid and primigravid mothers respectively examined had cord malaria. There was significant difference P=.002 comparing cord malaria infection prevalence and parity of pregnancy of matched mothers. The relationship between parasite malaria density and parity of pregnancy both in placental and cord malaria were not significant. Age group 20-25 years (45%) had the highest Prevalence while age groups 26-30 years recorded a prevalence of 33.3% for the primigravid and multigravid groups, respectively (P<0.05). The Geo mean range of 220 (3-8,250) vs. 23(2-6,412) parasite/µl of blood were recorded in primipare vrs multipare group. The result of this study showed moderate placental malaria infection and a low prevalence of cord malaria by microscopy. The presence of malaria parasites in cord blood at delivery and non in maternal placental blood was also demonstrated. There is a significant association between ITN (Insecticide-Treated Net) usage compliance rate and gravidity (primigravid vs. multigravid) among pregnant mothers. There is also a statistically significant relationship between age and gravidity in the occurrence of placenta malaria, as indicated by the chi-square test results. Conclusion: Antenatal exposure to malaria parasites may have profound effects on the fetus therefore prevention of malaria infection during pregnancy which may reduce the incidence of adverse perinatal outcomes should be strongly advocated.
