摘　　要：目的了解宁夏人体蛔虫感染现状和影响因素。方法采用分层整群随机抽样方法选取兴庆区等17个县(区)46个调查点,对调查对象采用改良加藤厚涂片法检查粪便中蛔虫虫卵。结果人群蛔虫感染率3.82%(670/17 557),标化感染率3.69%。地区以原州区最高,为8.99%;年龄以5～岁组感染率最高(6.38%)。回、汉民族蛔虫感染率间差异无统计学意义;学龄前儿童、学生蛔虫感染率高于其他职业人群(χ2=68.19,P<0.05)。轻、中、重度感染者分别占78.3%、18.8%和2.9%;蛔虫感染有明显的家庭聚集性,经济条件差、原始的耕作方式、饮用不洁水源和未开展过土源性线虫病防治工作等因素均是造成蛔虫流行的重要因素。结论宁夏全区蛔虫感染因素依然存在,提示今后仍需加强对南部山区等高感染地区,尤其是14岁以下儿童及农民等重点人群的蛔虫病综合防控工作。Objective To understand human roundworm infection status and influencing factors in Ningxia. Methods By stratif- ying cluster random sampling method, 46 survey sites in 17 counties or districts were selected and surveyed roundworm eggs using the Kato - Katz thick smear examination in feces in 2011. Results Crowd roundworm infection rate was 3.82% （670/17557）, the standardized prevalence was 3.69%, infection rate was the highest in Yuanzhou （8.99%）, and the infection rate （ 6.38% ） was highest in 5 to 9 age group. Roundworm infection rate in pre - school children and students was higher than that in other occupational groups （χ2 = 68. 19, P 〈 0. 05）. Light, moderate to severe infection, roundworm infection had obvious familial aggregation. Poor economic conditions, the original farming way, drinking dirty water and not to carry out soil - transmitted nematode control and other factors were important factors in causing roundworms popular. Conclusion The roundworm infection factors still exist in Ningxia, prompts need to be strengthened in the future high - infection on the southern mountain regions, especially in children under the aze of 14 and farmers, etc.
