目的 了解西藏自治区农田土壤中蛔虫卵污染状况,探讨蛔虫卵污染土壤的影响因素。方法 采用简单随机抽样方式在西藏自治区7市(地)抽取420个行政村作为监测点,调查监测点相关资料,采集监测点土壤样本,用饱和硝酸钠漂浮法对样本进行蛔虫卵检测;分析蛔虫卵及活蛔虫卵检出率与土壤环境、监测点所在农村的环境和行政卫生管理方法的相关性及影响因素。结果 2015—2016年,共检测690份土壤样本,蛔虫卵检出率为26.81%,活蛔虫卵检出率为16.67%。各地市蛔虫卵、活蛔虫卵检出率差异具有统计学意义(χ2分别为40.00和39.91,P<0.05)。其中2015年和2016年蛔虫卵检出率分别为30.68%、22.46%;活蛔虫卵检出率分别为14.79%、18.77%。多因素分析显示监测点农村社区建设以及卫生经费投入是蛔虫卵检出的重要影响因素;人居环境建设、农村社区建设、卫生村建立、植物根系复杂程度是活蛔虫卵检出的重要影响因素。结论 西藏自治区蛔虫感染风险依然存在,并存在地区差异性,分析结果提示仍需加强新农村建设,继续推动农村环境卫生工作的开展。

Objectives To analyze the status of ascaris lumbricoides eggs contamination in farmland soils in Tibet Autonomous Region, and to explore the factors influencing ascaris lumbricoides eggs-contaminated soils. Methods The survey was conducted in 420 administrative villages from 7 cities in Tibet by simple random sampling method. Saturated sodium nitrate floatation method was used to detect ascaris lumbricoides eggs in soil samples collected from monitoring stations in different cities in Tibet. The authors analyzed the correlation of detection rates of ascaris lumbricoides eggs and live ascaris lumbricoides eggs with soil environment and management methods of rural areas environment and administrative hygiene. Results The detection rate for ascaris lumbricoides eggs was 26.81% in 690 soil samples. The detection rate for live ascaris lumbricoides eggs was 16.67% in 690 soil samples. The detection rates of ascaris lumbricoides eggs and live ascaris lumbricoides eggs in all the cities were statistically significant(χ2 values were 40.00 and 39.91, respectively, P<0.05). The detection rates of ascaris lumbricoides eggs in 2015 and 2016 were 30.68% and 22.46%, respectively. The detection rates of live ascaris lumbricoides eggs in 2015 and 2016 were 14.79% and 18.77%, respectively. Multivariate analysis showed that the construction of rural communities and the input of health funds were important influencing factors for the detection of ascaris lumbricoides eggs. Construction of rural living environment, construction of rural communities, the establishment of hygienic villages, and complexity of plant roots were important factors affecting the detection of live ascaris lumbricoides eggs. Conclusions The risk of ascaris infection in Tibet still existed, and there were regional differences. The analysis results suggested that it was necessary to strengthen the new rural construction, and to continue promoting the rural environmental health work.
