ABSTRACT
Aims:The study aimed at determining the prevalence and risk factors for intestinal helminth infection among school-age children in Calabar, Cross River State, Nigeria. Study Design:Cross-sectional observational study was conducted in two Local Government Areas (Calabar South and Calabar Municipality) in Calabar. Place and Duration of Study:The study was carried out in Calabar, from May to October, 2018. Methodology:Faecal samples were collected from pupils in sterile dry specimen bottles with the use of applicator sticks and analyzed using sedimentation and floatation techniques. Data obtained was analyzed using Statistical Package for Social Sciences (SPSS) version 21. Results:Overall prevalence of intestinal helminth was 18.5%. Parasites recovered were Ascaris lumbricoides(9.3%), Trichuris trichiura(4.0%), Hookworm(2.6%), Taenia solium(0.9), Enterobius vermicularis (0.9), Strongyloides stercoralis (0.4%) and Schistosoma mansoni (0.4%) (P = 0000). Males (22.1%) were more infected than females (14.0%) in the study area (P = 0.031).Prevalence of intestinal helminths was lowest in age group 11-15 years (14.4%) and highest in age group 6-10 years (23.5%)(P = 0.005). After multivariate analysis, source of water [OR=3.355, 95% CI 1.448 –7.770], type of sewage system [OR=7.547, 95% CI 5.011 –8.358], hand washing before meal [OR=4.069, 95% CI 1.719 –9.631] and hand washing after defecation[OR=2.281, 95% CI 1.059 –4.917] were statistically associated with thedetected intestinal helminthic infections in faecal samples (p = .05). Conclusion:The presence of these intestinal parasites in these schools is a public health problem and there is therefore a need to prevent these infections by improving individual personal hygiene through health education, general sanitation and provision of adequate social amenities.
