目的调查攀枝花市中心城区与农村地区14岁以下儿童蛔虫、鞭虫感染率状况。为降低和控制中小学生寄生虫感染率提供依据。方法 2009、2010年连续2年从攀枝花市东区所属中小学和米易县乡镇中小学各抽1所学校,对一年级至五年级共1 003名学生进行粪便查蛔虫卵、鞭虫卵。结果攀枝花市总体上蛔虫及鞭虫感染率较低。城区儿童蛔虫感染率为1.89%,农村儿童感染率为8.92%,差异有统计学意义(χ2=25.17,P<0.01)。城区儿童鞭虫感染率为0.38%,农村儿童感染率为3.40%,差异有统计学意义(χ2=11.80,P<0.01)。高年级组和低年级组儿童蛔虫、鞭虫感染率差异无统计学意义(χ2=1.22,P>0.05;χ2=0.11,P>0.05)。男生组和女生组学生蛔虫、鞭虫感染率差异无统计学意义(χ2=0.05,P>0.05;χ2=0.18,P>0.05)。结论攀枝花市农村中小学生蛔虫及鞭虫感染率高于城区学生,应加强防治。
Objective To investigate the prevalence of roundworm and whipworm infections in children under 14 years of age in urban areas and rural areas in Panzhihua City. To reduce and control the parasitic infection rate of primary and secondary students provide the basis. Methods In 2009 and 2010, a total of 1 schools were enrolled from primary and secondary schools in the eastern district of Panzhihua City and primary and secondary schools in Miyi County for two years in succession. A total of 1 003 students from the first grade to the fifth grade were examined for stool ascaris eggs and whipworm eggs. Results Panzhihua City overall roundworm and whipworm infection rate is low. Ascaris infection rate was 1.89% in urban area and 8.92% in rural area. The difference was statistically significant (χ2 = 25.17, P <0.01). The prevalence of whipworm was 0.38% in urban areas and 3.40% in rural areas, with a significant difference (χ2 = 11.80, P <0.01). There were no significant differences in infection rates of roundworm and whipworm between high grade group and low grade group (χ2 = 1.22, P> 0.05; χ2 = 0.11, P> 0.05). There was no significant difference in the infection rates of roundworm and whipworm between boys and girls (χ2 = 0.05, P> 0.05; χ2 = 0.18, P> 0.05). Conclusion The prevalence of roundworm and whipworm in rural primary and secondary school students in Panzhihua is higher than that of urban students, and prevention and treatment should be strengthened.
