摘　　要：目的了解和分析2002-2009年上海市居民肠道寄生虫的感染状况和变化趋势,为今后的防治工作提供科学依据。方法在全市范围内设立监测点,以本市居民为监测对象,应用改良加藤法、直接碘涂片法和试管滤纸培养法进行寄生虫学检查。结果 8年共粪检35186人,查到8种肠道寄生虫,平均感染率为0.52%,年均下降幅度为8.32%。郊区人群的感染率(0.79%)高于中心城区(0.11%),两者差异有统计学意义(χ2=73.89,P<0.001);郊区和中心城区2005-2009年监测的感染率较2002-2004年分别下降了30.39%和88.0%,差异有统计学意义(χ2郊区=4.68,P<0.05;χ2中心城区=13.93,P<0.001);女性感染率(0.61%)显著高于男性(0.41%),两者差异有统计学意义(χ2=6.43,P<0.05);60岁以上年龄组(0.66%～0.93%)和农民(0.92%)的感染率较高,人群感染率有随文化程度的增高呈下降趋势(χ2=53.36,P<0.001)。结论上海市肠道寄生虫病监测点人群感染率已连续7年低于1%,表明肠道寄生虫感染已不是威胁上海市居民健康的主要危险因素,但在经济相对落后的郊区县仍应重视预防控制工作,老年人及农民为防治的重点人群。Objective To understand the current status and trends of the intestinal parasitic infection in Shanghai population from 2002 to 2009, so as to provide scientific evidences for making prevention and control measures. Methods The intestinal parasites surveillance sites in 19 districts/counties of Shanghai were surveyed.Each stool specimens of residents were examined for parasitic infection by Kato-Katz, iodine direct smear, and adding test tube culture in suburb sites. Results All of 8 species parasites were found from 2002 to 2009.The overall infection rate of intestinal parasite was 0.52% （183/35186）, at an annual decline of 8.32 percent.The overall infection rates （0.79%）in 21 312 person from 10 districts/counties in suburb was significantly higher than the result （0.11%） in 13 874 person from 9 center districts （~2=73.89,P〈0.001）, both infection rates were declined 30.39% and 88.0% from 2005-2009 to 2002-2004 （~2=4.68-13.93, P〈0.05,P〈0.001）, respectively. Female infection rate （0.61%）was significantly higher than that of male （0.41%, ~2=6.43, P〈0.05）. The highest infection rate was the age group above 60 （0.66%-0.93%）, and was in peasants（0.92%）. But the infection rate was decreased with the increase in education level （X~=53.36,P〈O.O01）. Conclusions The human infection rate of intestinal parasites was below 1% in Shanghai for seven consecutive years,revealing that intestinal parasitic infection are not important risk for people in Shanghai municipality in general. But it needs to enhance the surveillance in suburb, and the key population for the control is the old people, women and peasants.
