摘　　要：为了解宁夏土源性线虫感染现状, 2016-2017年在贺兰县、海原县及平罗县等3个监测点,每个监测点按地理方位划分为东、西、南、北、中5个片区,每个片区抽取1个乡镇的1个行政村开展监测,每个行政村整群抽取3周岁以上常住居民200人。收集调查对象粪样,采用改良加藤厚涂片法(一粪二检)查土源性线虫虫卵,采用问卷调查收集调查对象信息。结果显示, 2016-2017年,总感染率为1.4%(83/6 047),其中海原县的感染率(2.2%, 45/2 059)高于其他县区(P <0.05)。女性感染率为1.6%(50/3 099),男性感染率为1.1%(33/2 948),差异无统计学意义(P> 0.05)。≥60岁和40~59岁人群感染率较高,分别为1.7%(26/1 519)和1.8%(33/1 852),各年龄组间差异有统计学意义(P <0.05)。农民感染率最高,为1.6%(71/4 528),各职业组间差异无统计学意义(P> 0.05)。高中及以上文化程度感染率最高,为1.6%(17/1 034),不同文化程度组间差异无统计学意义(P> 0.05)。宁夏土源性线虫感染呈下降趋势,需采取分类指导措施,降低感染水平。To understand the current prevalence of soil-transmitted nematode (STN) infections in Ningxia, total 3 counties (Helan County, Haiyuan County and Pingluo County) were chosen and 5 villages were selected from each county, based on the evenly geographical distribution, as survey sites. Each site included 200 permanent residents with age of over 3 years old. The stool samples were collected from each enrolled villager and the eggs of STNs were examined under microscope in duplicate using modified Kato-Katz thick smear method. Questionnaire was used to collect the information of the respondents. Results showed that an overall prevalence of STN infections in Ningxia from 2016-2017 was 1.4%(83/6 047). The STN prevalence in Haiyuan County (2.2%, 45/2 059) was higher than that in other counties with significant difference (P < 0.05), however, there was no significant difference in prevalence between females (1.6%, 50/3 099) and males (1.1%, 33/2 948)(P > 0.05). Participants with age over 60 or between 40-59 had the highest prevalence (1.7%, 26/1 519 and 1.8%, 33/1 852, respectively) with statistical significance compared to that in other age groups (P < 0.05). Farmers had higher infection rate (1.6%, 71/4 528) than people with other occupations, and participants with education of high school and above had higher infection rate (1.6%, 17/1 034)(P > 0.05) than people with other education levels, but these difference had no statistical difference. The infection of soil-transmitted nematodes keeps a decreasing trend in Ningxia, and it is necessary to adopt different measures and guidance in different areas to reduce the infection.
