Determination of prevalence, risk factors and symptoms of urinary schistosomiasis among school children in Kaduna South Local Government Area, Kaduna State

Abstract

Schistosomiasis negatively impacts children’s health. Children expose themselves daily to schistosome infections due to lack of awareness and knowledge about the disease or the danger of infested water bodies. This study was aimed at determining the prevalence, risk factors and symptoms of urinary schistosomiasis among school children in Kaduna South Local Government Area, Kaduna State, Nigeria. Four hundred (400) consented school children submitted 10mL urine each and responded to structured questionnaires. Sediment of each urine sample was examined by light microscopy, after centrifugation at 3000 rpm for 5 min. Overall prevalence of urinary schistosomiasis was 4.5%. Both male and female children were equally infected (4.5% each). Older children between 13-17 years old were more infected (5.0%) and more at risk (OR = 2.982) than younger children (8-12 years old) who had 1.7% of the infection. No infection was recorded among children who had awareness about the disease. Water-based activities that served as significant risk factors for the infection included swimming in river (8.7%, P=0.016, OR= 3.064), fishing (12.2%, P=0.005, OR=3.942) and washing of clothes in river (17.4%, P=0.002, OR=5.459). Significant symptoms of urinary schistosomiasis identified were frequent urination (12.5%, P=0.023, OR=3.612), abdominal pain (10.0%, P=0.045, OR=2.880), and terminal haematuria (13.6%, P=0.002, OR=4.526). Infected individuals were more at risk of experiencing pains during urination (7.4%, OR=2.047). Unawareness promotes the spread of schistosomiasis among Nigerian children; their continuous exposure to infested water poses a greater risk. Creation of awareness amongst children will help to control their play habits in unsafe water bodies.
