OBJECTIVES: To assess the relationship between the infection status of children and their knowledge, attitudes, beliefs, and practices (KABP) related to urinary schistosomiasis.
DESIGN: Questionnaire survey.
SETTING: Nine schools in eight rural communities (total population: 4,636) in Ga and South Akuapem Districts, Ghana.
SUBJECTS: Four hundred and six children attending primary and secondary schools.
MAIN OUTCOME MEASURE: Schistosoma haematobium infection status of children and their KABP.
RESULTS: Of 354 children who responded and also submitted their urine samples, 297 (83.9%) tested positive for S. haematobium and the intensity of infection was 90 (95% CI: 74 to 110) eggs per 10 ml urine. General knowledge variables such as the knowledge of symptoms (p < 0.001), and knowledge of swimming or bathing in the river as a transmission route (p < 0.001) showed significant association for higher prevalence and intensity of infection. Treatment-seeking behaviour was not associated with the lower prevalence or intensity of infection. Practice variables such as washing clothes in the stream (p < 0.001) and fishing in the stream (p < 0.01) were significantly associated with both higher prevalence and higher intensity of infection. Children who knew of contact with river water as a transmission route reported more water contact activities (p < 0.001).
CONCLUSION: This study showed that highly symptom-aware people were heavily infected, and people frequently exposed to infested water were heavily infected. Moreover, highly symptom-aware people never constituted a group whose exposure was slight. Why was awareness of disease symptoms and general knowledge of the disease not linked to low infectivity? Why didn't awareness result in avoidance of infested water sources? This report highlights the urgent need to address these important questions in future research.
