A study on human intestinal helminths was conducted across eight primary schools in Nnewi South LGA, Anambra State. Stool samples were collected from 495 randomly selected pupils and examined using the direct smear technique to determine the prevalence of helminthic infections with predictor variables being regressed against outcome variables. A structured questionnaire was used to obtain biodata from the pupils to assess the association of intestinal helminths with socio-economic variables. The overall percentage of intestinal helminth-infected pupils had no statistical significance (p=0.1294). The probability of the outcome variable occurring rose by approximately 1.18 and 1.15 times for every unit higher in the predictor variable, as indicated by the positive coefficients for S1 and S4 schools (0.164821 and 0.136310). Only Trichuris infection exhibited a negative coefficient (-2.535188) among single infections and was significantly associated (p=0.0249). Ascaris + hookworm and Ascaris + Trichuris infections among the multiple infections revealed negative and positive coefficients (- 9.730077 and 1731.696, respectively), and they were strongly related (p=0.0001 and 0.0000). The number of infected students in (14-18) age range had a positive coefficient (0.020680) and was significantly (p=0.0441) associated with odds ratios of about 1.02, meaning that the odds of the dependent variables increase by about 1.02 times for every unit increase in
the independent variable. The proportion of males with the infection displayed positive coefficients (0.980800) and was significantly (p=0.0052) associated with odds ratios of about 2.67, indicating that the likelihood of outcome variables occurring increases by approximately 2.67 times for every unit rise in the predictor variable. Conclusively, the findings observed could be attributed to the poor socio-economic status and poor personal hygiene arising from the lack of basic amenities such as pipe-borne water and other sanitary facilities in the study location. Adequate health education on sanitation, provision of portable drinking water, toilet facilities and mass deworming programmes are highly recommended in the area.
