目的了解重庆市城市与农村地区儿童的蛲虫流行特征。方法选择重庆市城区和农村各1个区县作为调查点,每个调查点按东、西、南、北、中抽取1个乡镇(街道),每个乡镇(街道)抽取150名3～12岁儿童,每个点750名以上。采用圆底试管透明胶纸肛拭法,定性检查蛲虫卵。分析比较城市和农村地区儿童蛲虫感染率差异。结果重庆市儿童蛲虫感染率为6.85%,城市(2.14%)低于农村地区(12.13%)(χ2=62.14,P<0.01)。城市及农村儿童的性别间比较,蛲虫感染率差异无统计学意义(χ2城市=0.21,χ2农村=1.32,P均>0.05);同一性别间,城市与农村间比较,差异均有统计学意义(P均<0.01)。城市、农村不同年龄组间儿童感染率比较差异有统计学意义(χ2城市=12.65,χ2农村=34.22,P均<0.01);在同一年龄组间比较,除11～岁组外,其他年龄组间比较,差异均有统计学意义(P均<0.01)。城市各个年龄段儿童蛲虫感染率变动不大(χ2趋势=0.89,P>0.05);农村儿童感染率趋势随年龄的增加而降低(χ2趋势=3.36,P<0.01)。结论重庆市城市与农村儿童蛲虫感染具有不同特征,应针对不同地区、不同人群采取适宜的防治措施。
Objective To understand the prevalence of pinworm in children in urban and rural areas in Chongqing. Methods One district in Chongqing urban area and rural area was chosen as the investigation point. One township (street) was selected according to east, west, south and north of each survey point, and 150 3 ~ 12 Children over the age of 750 each. Using a round bottom tube transparent adhesive tape anal swab, qualitative examination of the worm eggs. Analysis and comparison of the prevalence of pinworm infection in urban and rural areas. Results The prevalence of pinworm in children in Chongqing was 6.85%, while in urban areas (2.14%) was lower than that in rural areas (12.13%) (χ2 = 62.14, P <0.01). There was no significant difference in the infection rates of chlamydia between urban and rural children (χ2 = 0.21, χ2 = 1.32, P> 0.05). The differences among the same gender, urban and rural areas were statistically significant Significance (P <0.01). The infection rate of children in different age groups in urban and rural areas was significantly different (χ2 = 12.65, χ2 = 34.22, P <0.01); in the same age group, in addition to the age group of 11 ~ Between the two groups, the differences were statistically significant (P <0.01). The prevalence of pinworm infection in children of all ages in cities did not change much (χ2 trend = 0.89, P> 0.05). The trend of infection rate in rural children decreased with age (χ2 trend = 3.36, P <0.01). Conclusion The infection of pinworm in urban and rural areas of Chongqing has different characteristics, and appropriate prevention and treatment measures should be taken for different regions and different populations.
