School-based interventions to enhance knowledge and improve case management of schistosomiasis: a case study from Hunan, China

This paper discusses an intersectoral health-related intervention, using cartoons and video-recording, print materials and face-to-face educational methods, to increase children's knowledge of schistosomiasis, which in turn might improve the case management of early diagnosis and treatment. The main components of the project were (i) the collaboration between the departments of public health and education and (ii) a randomized, controlled, school-based field trial conducted in the Dongting Lake region, China. Children in the experimental group (n = 604) and their parents participated in the educational programme. Control children (n = 527) received a 2 hour lecture about the disease. All participants were pre-tested, and retested five months after the conduct of the educational intervention. The results show significant changes among children and their parents in the experimental group related to knowledge about schistosomiasis and beliefs towards screening and treatment of the disease. Children in the experimental group also had better compliance than children in the control group for regular screening for schistosomiasis. These findings indicate that carefully designed education programmes are useful for providing both children and their families with information about the prevention and treatment of schistosomiasis. Intersectoral collaboration holds promise to deliver research-based interventions for enhanced knowledge of schistosomiasis and improved case management.
