目的了解崇左市中小学生肠道寄生虫感染现状,为进一步制定防治对策提供科学依据。方法整群随机抽取崇左市中小学校的在校学生,其中2009年抽取22所学校的8 274名学生,2013年抽取21所学校的7 992名学生。采取改良加藤法检验粪便中的蛔虫卵。结果 2009年崇左市中小学生蛔虫感染率为8.74%,2013年感染率为4.14%,2009年感染率高于2013年(χ~2=141.74,P<0.05);2009和2013年沿边境学生与非沿边境学生之间感染率差异均无统计学意义(χ~2值分别为2.80,0.22,P值均>0.05);2013年沿边境中学生感染率(4.18%)高于非沿边境中学生(2.96%),差异有统计学意义(χ~2=4.24,P<0.05)。结论学生蛔虫感染率总体受地域影响不明显,但呈现在某一时期以地方式作业的农村学生和区域性中学生偏高,其他学生人群感染并存的态势。应继续加强对学生进行蛔虫感染预防卫生知识的宣传教育。
Objective To understand the status of intestinal parasitic infection among primary and secondary school students in Chongzuo and to provide a scientific basis for further prevention and control measures. Methods A total of 8274 students from 22 schools were selected randomly from Chongzuo primary and secondary schools in 2009 and 7 992 students from 21 schools in 2013. Kato method to improve test Ascaris eggs in the feces. Results In 2009, the prevalence of Ascaris infection among primary and secondary school students in Chongzuo was 8.44%, the infection rate in 2013 was 4.14%, and the infection rate in 2009 was higher than that in 2013 (χ ~ 2 = 141.74, P <0.05). In 2009 and 2013, There was no significant difference in infection rates between non-border students and non-border students (χ ~ 2 = 2.80,0.22, P> 0.05). In 2013, the infection rate among middle school students (4.18% (2.96%), the difference was statistically significant (χ ~ 2 = 4.24, P <0.05). Conclusions The prevalence of roundworm infection in students is not significantly affected by the region as a whole. However, there is a tendency that rural students and regional high school students who work locally in a certain period are in high status and other student populations coexist. Should continue to strengthen the prevention and treatment of Ascaris infection in students knowledge of health education.
