Abstract

Schistosomiasis japonica continues to be an important zoonotic disease in People's Republic of China (P.R. China), despite decades of dedicated control efforts. Different interventions for its control including chemotherapy of humans and animals, mollusciciding, environmental modification, and health education have been implemented at various stages of the control efforts and in different combinations, resulting in remarkable achievements. Here, we present a systematic review and meta-analysis of the documented effectiveness of health education to reduce schistosomiasis japonica transmission in P.R. China. A total of 10 relevant publications were identified and included in the meta analysis. The reported results indicate that the prevalence of Schistosoma japonicum infection in humans and schistosomiasis-related knowledge are significantly influenced by health education. The implementation of health education over more than 2 years was associated with an overall schistosomiasis japonica prevalence decrease of 6% (95% CI: 2%, 11%) and an overall increase of 51% (95% CI: 41%, 61%) in schistosomiasis-related knowledge after controlling for confounding factors. Among control groups, the impact on the prevalence of schistosomiasis japonica and relevant knowledge levels was not significant. The relative risk (RR) of an infection with S. japonicum following health education lasting more than 2 years was 0.43 (95% CI: 0.24, 0.78). In summary, a considerable effectiveness of health education with regard to preventing S. japonicum infections in P.R. China and increasing relevant knowledge is documented in the extant literature. This suggests that the effectiveness of health education may be considerable, particularly after its long-term implementation.
