Prevalence and Determinants of Intestinal Parasitic Infections among Pregnant Women Receiving Antenatal Care in Kasoa Polyclinic, Ghana

Abstract EN

Background.

Intestinal parasitic infections affect pregnant women worldwide.

The infection has been implicated in causing life-threatening conditions in both gravid women and their developing foetus.

Sub-Saharan Africa is known to harbor the greatest proportion of intestinal parasitic infections largely due to socioeconomic and environmental factors.

In Kasoa, Southern Ghana, there is paucity of data on the prevalence and associated factors of intestinal parasitic infections among pregnant women.

Objective.

The aim of the study was to determine the prevalence of intestinal parasitic infections and associated factors among pregnant women attending antenatal care in Kasoa Polyclinic.

Methods.

A hospital based analytical cross-sectional study was carried out among three hundred (300) conveniently sampled pregnant women receiving antenatal care services at the Kasoa Polyclinic.

Structured questionnaires were administered to the study participants to assess sociodemographic and other possible factors.

Stool samples were collected from each pregnant woman and examined for the presence of intestinal parasites by microscopy using direct wet mount as well as formol-ether sedimentation techniques.

Results.

Overall prevalence of intestinal parasites was 14.3% (95% CI 11–19%).

Entamoeba histolytica (5.0%) was the most predominant parasite species identified followed by Ascaris lumbricoides (4.3%), Giardia lamblia (2.3%), Trichuris trichiura (1.3%), Schistosoma mansoni (0.3%), Hookworm (0.3%), Hymenolepis nana (0.3%), and Isospora belli (0.3%).

Age > 30 years (AOR = 0.17, 95% CI = 0.06–0.48; p=0.001), multigravidity (AOR = 0.43, 95% CI = 0.19–0.97; p=0.043), and 2nd and 3rd trimesters (AOR = 4.73, 95% CI = 1.36–16.49; p=0.015) were independently associated with intestinal parasitic infections among pregnant women.

Conclusions.

A prevalence of 14.3% pregnant women compared to previous studies in Ghana is relatively low.

It however suggests that intestinal parasitic infection is still a problem.

The major factors noted were age, gravidity, and gestational age.

Routine stool examination and provision of public health education are recommended to prevent infection of pregnant mothers and their unborn babies.
