BACKGROUND: The parasite Schistosoma haematobium causes urogenital schistosomiasis, a chronic infectious disease that occurs mainly among school-age children.
OBJECTIVE: The prevalence of S. haematobium infection and level of intensity relative to age, gender and status of selected serum micronutrients among school-age children were investigated in suburban communities in Bekwarra, Nigeria.
METHODS: This cross-sectional school-based study randomly recruited 353 children aged between 4 and 16 years from five elementary schools between June 2019 and December 2019. We gathered socio-demographic data about each child using a semi-structured questionnaire. Blood samples were collected for micronutrient analysis and urine samples were collected for assessment of S. haematobium infection.
RESULTS: A total of 57 (16.15%) school-age children were infected with S. haematobium. Girls (n = 34; 9.63%) were more frequently infected than boys (n = 23; 6.52%). Infection was most frequent among children aged 8-11 years (n = 32; 23.19%) and was significantly associated with age (p = 0.022) and gender (p < 0.001). Serum levels of iron, calcium, copper and zinc among infected children were significantly lower than those of non-infected children. Intensity of infection was negatively associated with iron (r = -0.21), calcium (r = -0.24), copper (r = -0.61; p < 0.001) and zinc (r = -0.41; p < 0.002).
CONCLUSION: This study showed that S. haematobium infection adversely impacted the micronutrient status of school-age children in suburban Nigeria. Measures to lower the prevalence of schistosomiasis among school-age children, including efficient drug distribution, education campaigns and community engagement, are necessary.
WHAT THIS STUDY ADDS: This research emphasises the significance of implementing infection prevention and control interventions to mitigate the transmission and prevalence of schistosomiasis among school age children.
