prevalence of intestinal parasitic infection and associated risk factors among primary school-aged children (5 - 15 years) in southern nigeria

Background: in nigeria, intestinal parasitic infection (ipi) is one of the neglected tropical diseases of public health importance. objectives: this study investigated intestinal parasitic infection and associated risk factors among primary school-aged children in sagbama local government area, bayelsa state, nigeria. methods: a total of 622 stool samples (335 males and 287 females) were collected from 13 primary schools in nine communities and analyzed using parasitological techniques (direct wet mount and formal ether concentration method). the tukey honest significance difference test (hsd) was used to determine the association and variation between prevalence and socioeconomic variables. results: nine parasite species were encountered with a total prevalence of 23.95%, including ascaris lumbricoides (7.32%), entamoeba histolytica (4.98%), strongyloides stercorals (2.09%), giardia lamblia (1.93%),hookworm(1.77%), trichuris trichiura (1.61%), schistosoma mansoni (1.45%), diphyllobotium latium (0.64%) and fasciola hepatica (0.32%). a total of 4.50% of infections were mixed. with 30.26%, the age group 5 - 7 years had the highest infection rate. the second most prevalent age group was 8 - 10 years old (26.53%), while the least prevalent age group was 14 - 16 years old (12.60%). males were more infected with the disease, 25.07%, than females, 22.65%. ascaris lumbricoides were the most predominant parasites encountered across the nine communities. there was a significant difference between the infected population in the nine communities at p < 0.05 (p = 0.001). conclusions: there was a relatively high prevalence of intestinal parasitic infection among primary school children in sagbama local government area. improved sanitation, safe drinking water, and a step-up in health education in the communities will reduce the exacerbation of the infection in the area.
