Parasitic infections among pregnant women at first antenatal care visit in northern Ghana: A study of prevalence and associated factors

Abstract

Background: Parasitic infections remain widespread in developing countries and constitute a major public health problem in many parts of sub-Saharan Africa. It is prevalent among children under 5 years and pregnant women; however, studies among the later high risk group is limited in the northern part of Ghana. Here, we evaluated the prevalence and associated factors of parasitic infections among pregnant women at first antenatal care visit in northern Ghana. Methods: This was a cross-sectional study conducted at the Department of Obstetrics and Gynecology, Bolgatanga Regional Hospital, Upper East Region-Ghana. A total of 334 consecutive consenting pregnant women were included. Questionnaires were administered to obtain socio-demographic data. Venous blood, stool and urine samples were collected for parasite identification using microscopy. Factors associated with parasitic infections were evaluated using regression models. Statistical analysis was performed using R. Results: Parasitic infections identified were giardiasis (30.5%), P. falciparum malaria (21.6%) and schistosomiasis (0.6%). Polyparasitic infection was identified in 6.6% of the population. Increasing age [Age of 20-29 years: AOR = 0.16, 95% CI (0.06-0.38); Age of 30-39 years: AOR = 0.21, 95% CI (0.08-0.50); Age >39 years: AOR = 0.30, 95% CI (0.11-0.83)] was associated with lower odds whiles presence of domestic animals [AOR = 1.85, 95% CI (1.01-3.39)], being in the second trimester of pregnancy [AOR = 2.21, 95% CI (1.17-4.19)], having no formal education [AOR = 3.29, 95% CI (1.47-7.35)] and basic education as the highest educational level [AOR = 6.03, 95% CI (2.46-10.81)] were independent predictors of increased odds of giardiasis. Similarly, having no formal education [AOR = 2.88, 95% CI (1.21-8.79)] was independently associated with higher odds of P. falciparum malaria. The use of insecticide treated net (ITN) [AOR = 0.43, 95% CI (0.21-0.89)] and mosquito repellent [AOR = 0.09, 95% CI (0.04-0.21)] were independent predictors of lower odds of P. falciparum malaria. Conclusion: Giardiasis and P. falciparum malaria are common among pregnant women in northern Ghana. The major associated factors of giardiasis are lack of or low level of formal education, the presence of domestic animals and being in the second trimester of pregnancy. Increasing age confers protection against giardiasis. Likewise, lack of formal education is an associated factor for P. falciparum malaria among pregnant women in northern Ghana. The use of ITN and mosquito repellents reduce the risk of P. falciparum malaria. Given the possible role of parasitic infections in adverse pregnancy outcomes, our findings highlight the need for regular screening and treatment of infected women in the northern parts of Ghana. Public health education and improving socio-economic status could help reduce the risk of parasitic infections among pregnant women in the region.
