目的观察血吸虫病重度疫区健康促进干预控制学生感染的效果。方法应用实验研究方法 ,于基线调查后,实验组连续3年应用“信息传播+行为参与+行为激励”健康促进模式干预,并评价干预效果。结果干预前,实验组与对照组学生血防知识知晓率、血防态度正确率、接触疫水率和血吸虫感染率差异均无统计学意义(P>0.05)。干预1年,实验组学生血防知识知晓率和血防态度正确率分别由干预前12.30%、11.51%提高到97.89%和99.16%,接触疫水率和血吸虫感染率分别由干预前16.84%和9.52%均降至0,差异均有统计学意义(P<0.05)。对照组干预前与干预1年上述各项指标变化均无统计学意义(P>0.05)。干预2～3年,实验组学生均未见接触疫水者和血吸虫感染者。结论 “信息传播+行为参与+行为激励”健康促进模式干预可有效控制和预防血吸虫病重疫区学生感染血吸虫。
Objective To observe the effect of health promotion intervention on controlling schistosomiasis infection in severe epidemic area of schistosomiasis. Methods The experimental research method was used. After the baseline survey, the experimental group used “information dissemination + behavioral participation + behavioral stimulation” health promotion mode intervention for 3 consecutive years and evaluated the intervention effect. Results Before the intervention, there was no significant difference between the experimental group and the control group in the awareness of blood-borne knowledge, the correct rate of blood-borne attitude, the contact immunization rate and the infection rate of schistosomiasis (P> 0.05). The intervention rate and schistosomiasis awareness rate of experimental group were increased from 12.30% and 11.51% before intervention to 97.89% and 99.16%, respectively, from 16.84% and 9.52% before intervention All decreased to 0, the difference was statistically significant (P <0.05). There was no significant difference between the control group before intervention and one year after intervention (P> 0.05). Intervention 2 to 3 years, the experimental group of students were not exposed to water and schistosome infection. Conclusion “Information dissemination + behavior participation + behavioral stimulation ” intervention of health promotion model can effectively control and prevent schistosomiasis infection in severe infection of schistosomiasis.
