Objective To learn and evaluate the effect of health education of schistosomiasis in the Three Gorges Reservoir Area, so as to provide scientific basis for establishing the comprehensive prevention and control model in potential epidemic area of schistosomiasis. Methods Through adopting the multi-stage stratified cluster sampling method, the questionnaires were distributed to residents selected randomly from the demonstration, inside and outside control areas. The survey data were input with EpiData 3.0 software by two reviewers, and the differences among groups were analyzed by using SPSS 18.0 software to further evaluate the effect of health education of schistosomiasis. Results All the questionnaires distributed to 1 420 residents were retrieved (100%). The results of analysis showed that for the residents in the demonstration area, the average score of being aware of schistosomiasis prevention was (7.51±2.89), which was markedly higher than those in the inside (2.52±2.97) and the outside (3.13±3.51) control areas, with significant differences (Plt;0.05); and the passing rates were 78.15%, which was also obviously higher than those in the inside (17.26%) and the outside control areas (32.16%), with significant differences (Plt;0.05). Conclusion The health education of schistosomiasis can improve residents’ knowledge about schistosomiasis prevention, and it is very important to prevent and control the potential prevalence of schistosomiasis in the Three Gorges Area.
Objective To learn the impact of health education on schistosomiasis among high school students in Wanzhou area of Three Gorges Reservoir, and to evaluate its effects. Methods The stratified multi-level cluster randomized sampling was used to survey 566 high school students in Wanzhou and Yunyang areas, and the questionnaire was used to investigate their recognition of schistosomiasis. Results After one-year health education on schistosomiasis, the passing rate of the knowledge about schistosomiasis prevention among high school students in demonstration area raised from 9.43% to 98.87% (χ2=463.46, P=0.000), which was higher than that of the inside and outside control areas (χ2=312.92, P=0.000); the passing rate of the attitude and belief of schistosomiasis prevention were 98.12%, which was higher than that of the inside and outside control areas (χ2=109.49, P=0.000); 56.02% of high school students in demonstration area had no susceptible behavior of schistosomiasis, which was higher than that of the inside and outside control areas (χ2=237.53, P=0.000). Conclusion Health education on schistosomiasis can efficiently improve the awareness of schistosomiasis prevention among high school students, and has important meanings for controlling potential epidemics and spread of schistosomiasis in Wanzhou area of Three Gorges Reservoir.
