祥云县寄生虫病综合防治示范区人群干预措施效果评价

目的评价祥云县寄生虫病综合防治示范区实施人群干预措施的效果,为制定合理的寄生虫病防治措施提供参考依据。方法 2006年对示范区土源性线虫感染率进行基线调查后,连续3年实施健康教育、药物驱虫、改水、改厕和改造环境等干预措施,2009年对寄生虫病综合防治效果进行评估。结果 2009年居民寄生虫病防治知识知晓率为86.96%,与2006年（35.20%）相比,上升了147.05%,差异有统计学意义（χ2=122.95,P=0）;2009年居民健康行为合格率（97.10%）与2006年（48.00%）相比,上升了102.30%,差异有统计学意义（χ2=128.27,P=0）。2006年示范区人群寄生虫总感染率为19.14%,2009年下降至2.47%,两者差异有统计学意义（χ2=162.88,P=0）。在土源性线虫感染中,2006年和2009年蛔虫感染率均为最高,分别为18.74%和2.08%。结论祥云县寄生虫病综合防治示范区实施以健康教育为先导、以传染源控制为主的综合防治措施效果显著,达到了降低人群寄生虫感染率、增进人民群众健康水平的目的。

Evaluation on intervention measures of comprehensive control for parasitic diseases in demonstration plot of Xiangyun County

Objective To evaluate the effect of comprehensive intervention measures to control and prevent parasitic diseases in the demonstration plot of Xiangyun County,so as to provide the evidence for establishing appropriate measures of parasitic diseases control and prevention.Methods The baseline data of soil-transmitted nematode infections were obtained in 2006.A series of intervention measures,including health education,deworming,drinking water improvement,latrine improvement,and environment reconstruction,were performed for three years and the effect of the comprehensive intervention measures was evaluated by the national expert group in 2009.Results The awareness rate of parasitic disease knowledge of residents in 2009（86.96%） was significantly higher than that in 2006（35.20%）（χ2]=122.95,P 0.01）.The passing rate of resident health behavior in 2009（97.10%） was significantly higher than that in 2006（48.00%）（χ2]=122.95,P 0.01）.The general infection rate of parasites in 2009（2.47%） was significantly lower than that in 2006（19.14%）（χ2]=162.88,P 0.01）.Of soil-transmitted nematode infections,the infection rates of Ascaris lumbricoides in both 2006 and 2009 were the highest and the rates were 18.74% and 2.08%,respectively.Conclusions In the demonstration plots for parasitic diseases control and prevention of Xiangyun County,the effect of the comprehensive intervention measures which take health education as the forerunner and give priority to control source of parasite infection is remarkable.The measures implemented can achieve the purpose to reduce the infection rates of parasites and improve human health.
