Parasitic infections and risk factors associated with Amoebiasis among pregnant women attending antenatal clinics in primary health care centres in Lagos Mainland, Lagos, Nigeria

The prevalence of amoebiasis was investigated among pregnant women using a gold standard microscopy method. Stool samples were collected from pregnant women, from two primary health care centers (Iwaya and Ebute-metta). The study involved 203 pregnant women during their visits to the antenatal clinic in Primary health centres at Lagos Mainland from June – October, 2016. Each participant was interviewed using questionnaires to relate prevalence and risk factors to their socio-demographic characteristics. Among these pregnant women, 120 respondents provided their stool samples and this was parasitologically screened with 0.8% prevalence of Entamoeba histolytica infection, 7.5% with Entamoeba Coli, 0.5% with Ascaris lumbricoides, and 0.8% infection with Hookworm. A prevalence of 0.8% for the mixed infection of Ascaris lumbricoides with Entamoeba histolytica, and a prevalence of 1.7% for the mixed infection of Entamoeba coli and Entamoeba histolytica was recorded. Significant association (p<0.05), was established between infection and diarrhoea, and the residence of the pregnantwomen.Socio - demographic factors like age, sex, socio-economic status, type of toilet, source of drinking water (p>0.05) showed no significant association with amoebiasis prevalence. In conclusion, E. histolytica infection is generally low in Lagos state owing to good environmental sanitation within Lagos metropolis. Efforts should therefore be geared towards its elimination by provision of water for Lagos residents.
