目的了解医学院学生10年来人体蠕形螨的感染现状,为治疗和预防提供依据。方法采用透明胶带粘贴法,对1999～2008级来自宁夏地区各县、市、区、不同医学专业学生共1303名进行蠕形螨感染调查。胶带粘于载玻片上置于光镜下检查,将各种数据做统计学分析。结果共调查1303名学生。逐年感染率为34.11%～6.11%,平均感染率为19.26%。男生总体感染率18.18%,女生总体感染率20.20%,男生与女生感染率差异无统计学意义(P﹥0.05)。回族学生感染率28.98%,汉族感染率15.74%,回族与汉族学生感染率差异有统计学意义(P﹤0.01)。皮脂蠕形螨感染占30.28%(76/251),毛囊蠕形螨感染占68.13%(171/251),混合感染为1.59%(4/251)。Ⅰ度感染占83.27%(209/251)。结论 2000～2009年10年间总体感染率呈现下降趋势,回族学生感染率高于汉族,这可能与社会经济水平、人们生活质量的逐步提高、人群文化素质及卫生条件逐年改善,除螨洗涤用品、化妆用品的出现,媒体医药广告的普及、回族生活习惯、习俗、饮食习惯有关。
Objective To understand the status of human demodex infection in medical college students over the past 10 years and to provide basis for treatment and prevention. Methods A total of 1,303 students from different counties, cities and districts of Ningxia from 1999 to 2008 were enrolled in the study. Adhesive tape is placed on the slide under the light microscope to check the various data for statistical analysis. Results A total of 1303 students were investigated. The annual infection rate was 34.11% ~ 6.11%, the average infection rate was 19.26%. The overall infection rate was 18.18% for boys and 20.20% for girls, and there was no significant difference between boys and girls (P> 0.05). The infection rate of Hui students was 28.98%, the infection rate of Han people was 15.74%, and there was significant difference between Hui and Han students (P <0.01). Demodex infection accounted for 30.28% (76/251), hair follicle mite infection accounted for 68.13% (171/251), mixed infection was 1.59% (4/251). I degree infection accounted for 83.27% (209/251). Conclusion The overall infection rate in the 10 years between 2000 and 2009 showed a downward trend, and the prevalence of Hui students was higher than that of the Han people. This may be related to the social and economic level, the gradual improvement of people’s living quality, the gradual improvement of the cultural quality and hygiene conditions of the population. In addition to mite cleaning products, The emergence of cosmetics, the popularity of media medical advertisements, Hui life habits, customs, eating habits.
