【摘要】 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。更多还原

【Abstract】 Objective To understand the prevalence and characteristics of Enterobius vermicularis infection in city and rural areas of Chongqing city. Methods 1 rural county and 1 urban district were selected. Children aged 3～12 years from 5 different towns were investigated. 150 children were randomly selected from each town. The eggs of Enterobius vermicularis from the fecal materials of children were examined by the adhesive cellophane anal swab method. The prevalence and characteristics of Enterobius vermicularis infection in the rural and urban areas were analyzed. Results The infection rate in the urban areas (2.14%) was lower than the rural areas (12.13%) (χ2=62.14,P<0.01). There was no significant difference in the infection between male and female in both the city and rural areas (P>0.05), but there was a significant difference in the infection of subjects of the same sex(P<0.01). There was a significant difference in the infection of among different aged groups (χ2city=12.65,χ2rural=34.22, P<0.01). There was also a significant difference in the infection of subjects of the same aged group, except for the age 11～12 years old(P<0.01). There was no significantly difference in the infection in all age group in the city (χ2trend=0.89, P>0.05), but there was a difference in the rural areas (χ2trend=3.36,P<0.01). The education background of the parents has an influence on the infection rate. Conclusion To control the transmission of Enterobius vermicularis, suitable measures should be made in different areas.更多还原
