To study an intervention model of "schools without infected students with schistosoma japonica", to control and prevent students from schistosoma infection.
Twelve primary schools of four heavy endemic counties (districts) with schistosomiasis in the Poyang Lake areas were selected as the study fields, of which, ten schools were the experimental groups, and the other two schools were the control groups by cluster random sampling. All enrolment students were the target population. The baseline survey was carried out in 2005, and an intervention model, "information dissemination + behavior participation + behavior encouragement", was applied in the experiment groups in 2006 - 2008, then the effect of intervention was assessed.
Before intervention (2005), the anti-schistosomiasis knowledge awareness rate of experimental and control groups were 14.75% (324/2196) and 16.58% (91/549), and the different was not significant (χ(2) = 1.14, P > 0.05); the rate of accurate attitude of anti-schistosomiasis were 14.71% (323/2196) and 11.84% (65/549) in experimental and control groups, and the difference was not significant (χ(2) = 2.98, P > 0.05); the rate of contacting infected water were 15.44% (18 988/122 976) and 15.03% (4622/30 744) in experimental and control group and the difference was not significant (χ(2) = 3.13, P > 0.05); and the infection rate of schistosomiasis of experiment control groups were 9.65% (212/2196) and 10.56% (58/549), the difference was not significant (χ(2) = 0.41, P > 0.05). After one year intervention (2006), the anti-schistosomiasis knowledge awareness rate of experimental and control groups were 97.79% (2032/2078) and 18.11% (98/541), and the different was significant (χ(2) = 1794.31, P < 0.01); the rate of accurate attitude of anti-schistosomiasis were 99.09% (2059/2078) and 13.49% (73/541) in experimental and control group, and the difference was significant (χ(2) = 2077.45, P < 0.01). After 1 - 3 years intervention (2006 - 2008), there were no any contactors with infected water and infectors with schistosome in students of the experiment group in successive 3 years. While in the control group of the same period, the rate contacting infected water were 16.12% (4884/30 296), 11.11% (3079/27 720) and 12.25% (3451/28 168); the infection rate of schistosomiasis were 8.87% (48/541), 7.47% (37/495) and 7.95% (40/503), respectively.
The intervention model of health promotion, "information dissemination + behavior participation + behavior encouragement", can effectively control and prevent students from infecting schistosoma japonica in heavy endemic areas with schistosomiasis.
研究“无日本血吸虫感染学生学校”干预模式，控制和预防学生感染血吸虫。
选取鄱阳湖区4个血吸虫病重流行县（区）的12所小学作为研究现场，采用整群随机抽样法，其中10所学校为实验组，另2所学校为对照组。所有入学学生为目标人群。2005年进行基线调查，2006 - 2008年在实验组应用“信息传播+行为参与+行为激励”干预模式，然后评估干预效果。
干预前（2005年），实验组和对照组的血吸虫病防治知识知晓率分别为14.75%（324/2196）和16.58%（91/549），差异无统计学意义（χ(2)=1.14，P>0.05）；实验组和对照组的血吸虫病防治正确态度率分别为14.71%（323/2196）和11.84%（65/549），差异无统计学意义（χ(2)=2.98，P>0.05）；实验组和对照组接触疫水率分别为15.44%（18988/122976）和15.03%（4622/30744），差异无统计学意义（χ(2)=3.13，P>0.05）；实验组和对照组血吸虫感染率分别为9.65%（212/2196）和10.56%（58/549），差异无统计学意义（χ(2)=0.41，P>0.05）。干预1年后（2006年），实验组和对照组的血吸虫病防治知识知晓率分别为97.79%（2032/2078）和18.11%（98/541），差异有统计学意义（χ(2)=1794.31，P<0.01）；实验组和对照组的血吸虫病防治正确态度率分别为99.09%（2059/2078）和13.49%（73/541），差异有统计学意义（χ(2)=2077.45，P<0.01）。干预1 - 3年（2006 - 2008年）后，实验组学生连续3年无接触疫水者和血吸虫感染者。而同期对照组接触疫水率分别为16.12%（4884/30296）、11.11%（3079/27720）和12.25%（3451/28168）；血吸虫感染率分别为8.87%（48/541）、7.47%（37/495）和7.95%（40/503）。
“信息传播+行为参与+行为激励”的健康促进干预模式可有效控制和预防血吸虫病重流行区学生感染日本血吸虫。
