Status of Intestinal Helminth Infection in Schools Implementing the Home-Grown School Feeding Program and the Impact of the Program on Pupils in Anambra State, Nigeria

Purpose Intestinal helminthiasis among pupils is a major impediment to their well-being and development. This 2-year study determined how home-grown school feeding programme (HGSFP) impacted on pupils' school attendance and created opportunity for more children to assess interventions geared towards the prevention and possible elimination of intestinal helminthiasis. Methods Faecal samples were collected from 1677 consented pupils and examined for helminths using Kato-Katz technique. Pupils were treated with 40 mg Levamisole (anti-helminthic) and re-examined. Structured questionnaires and focus group discussions were used to determine anthropometric indices and risk factors. Results A 6% prevalence rate which was not significant with respect to sex or age was observed. Helminth parasites observed were Ascaris lumbricoides (4.4%), Trichuris trichiura (0.8%), Hookworm spp. (0.2%), and Taenia spp. (0.5%). Two pupils (1.98%) recorded high intensity of infection (epg) while 98.02% had light infection. Ascaris lumbricoides voided following treatment were 290. The Body Mass Index (BMI) indicated that infected pupils had lower values (14.6317) compared to uninfected pupils (19.2003). The HGSFP significantly improved school attendance by 30%. Lack of knowledge about transmission (P = 0.0004), hand hygiene (P = 0.01) and usage of toilet (P = 0.01) were risk factors observed. Conclusion/significance Intestinal helminthiasis remains a public health problem among pupils because environmental and behavioural risk factors persist. HGSFP improved school attendance and created opportunity for more inclusive participation of school-aged children for deworming. This has great potential in fast-tracking the elimination of intestinal helminthiasis. The present study consequently advocates the need to sustain HGSFP in schools.
