Plasmodium falciparum Infection and Associated Risk Factors in Pregnant Woman Attending Bafang District Hospital, Semi-Rural Area, West Region of Cameroon: A Cross-Sectional Study

Background: Malaria is a major public health problem in countries with limited resources. This morbid and fatal infection mainly affects vulnerable groups with weak immunity, such as children and pregnant women. In pregnant women, malaria leads to the occurrence of anaemia with the consequences of abortion, low birth weight (LBW) of the child and death of the baby. This study aimed to determine the Plasmodium falciparum (P. falciparum) infection and associated risk factors among pregnant women attending the Bafang district hospital (BDH). 
Methods: A hospital based quantitative cross-sectional and descriptive study were conducted from May 30th, to June 24th, 2022 among 156 pregnant women attending the BDH, West Region of Cameroon. All pregnant women consented to participate in the study without any constraint. Blood samples were collected, thick film and stained blood smear examined for Plasmodium trophozoites and gametocytes respectively. Statistical analyses were performed using Epi Info v. 7 software with any p-value<0.05 considered statistically significant. 
Results: The age of the study participants ranged from 14 to 48 years old (mean age of 27.41 ± 6.67 years). Of the 156 pregnant women tested, 25% (95% CI: 18.42%-32.55%) were infected with P. falciparum, infection was high in pregnant women aged < 30 years old (66.67%), in non-salaried (82.05%), in pregnant women in the second trimester of pregnancy (48.72%) with no difference statistically significant (p-value<0.05). Furthermore, the use of mosquito nets (OR= 3.88, 95% CI: 1.78-8.43, p-value=0.0003), taking intermittent preventive treatment (IPT) (OR= 2, 95, 95% CI: 1.31-6.59, p-value=0.006) and the number of IPT doses (p-value=0.0006) were risk factors statistically associated with P. falciparum infection. 
Conclusion: This study revealed a high prevalence of P. falciparum among pregnant women attending BDH. The use of mosquito nets, the taking of IPT were the factors statistically associated with the infection.
