Intervention Effect Study On Health Education In Schistosomiasis Control In Yunnan Province

Objective: To study the effect of health education in schistosomiasis control work at big mountain areas.Methods:To select two natural villages with similar basic situation and epidemic situation etc in Dali county to study the intervention effect of health education from 1994 to 1996. One village is experimental group adopted intervention measure of health education + chemotherapy + snail elimination in key areas, another village is comparison group adopted intervention measure of chemotherapy + snail elimination in key areas, and then comparing with the intervention effect after implementing two different measures. All data are analyzed by SPSS statistics software package on the computer.Results:After implementing health education, passing rate of knowledge on schistosomiasiscontrol of students and adults increased by 65.46% and 31.94% respectively (P<0.001), awareness rate increased by 73.64% and 47.09% respectively (P<0.001) , compliance rate for chemotherapy increased by 41.67% and 28.67% respectively (P<0.001), frequencies of contacting cercariae-infested water declined by 42.07% and 26.58% respectively (P<0.001). Comparing with before and after implementing health education, the number of students who took self-protecting change little, and adults who took self-protecting change greatly(P<0.001), infection rate of students and adults decreased by 90.12% and 73.30%(P<0.001), acute infected cases of schistosomiasis decreased. Knowledge and awareness on schistosomiasis control and prevention of target population exist positive correlation with infection of schistsomiasis. More knowledge and awareness on schistosomiasis control and prevention ,lower infection of schistosomiasis. Intervention effect of health education to students is better than adults. Cost-effect analysis indicate that after 3.76 yuan RMB used for health education per 100 people, students infection rate of schistosomiasis will decline by 1%, after 8.14 yuan RMB used for health education per 100 people,students compliance rate for chemotherapy will increased by 1% ; after 3.63 yuan RMB used for health education per 100 people, adults infection rate of schistosomiasis will decline by 1%, after 11.83 yuan RMB used for health education per 100 people, adults compliance rate for chemotherapy will increased by 1%.Conclusions: Health education is an important measure to prevent and control schistosomiasis, it has the effect with low-cost, high-outcome and good - effectiveness. Health education combined chemotherapy with snail elimination in key areas is an effective strategy to prevent and control schistosomiasis in Yunnan Province.
