目的了解医院就诊妇科病人阴道毛滴虫感染情况,为科学防治提供依据。方法采用生理盐水直接涂片法检查卢龙县医院2005—2008年妇科门诊7376例就诊病人的阴道分泌物,了解阴道毛滴虫感染情况,对检查结果进行分析。结果4年阴道毛滴虫平均感染率8.45%(623/7376);每年感染率无明显差异,但逐年递减;4年中35岁～年龄组感染率为11.78%(1491/1265),明显高于其他年龄组;40岁～感染率次之为11.49%(131/1140);但2007年35岁～年龄组感染率为11.40%(39/342),略低于40岁～年龄组感染率11.80(36/305);20岁以下年龄组感染率最低,为0.90%(2/221)。季节感染率无明显差异,11月、12月、1月份感染率高于其他月份,分别为9.15%、8.94%、9.88%。农村居民感染率(8.23%),明显高于城镇(1.17%)。结论被调查病人阴道毛滴虫感染率高于全球女性感染率(3.1%),低于国内以往同类调查水平;35～45岁为阴道毛滴虫感染高发期;季节对阴道毛滴虫感染无明显影响。 Objective To understand the prevalence of Trichomonas vaginalis infection in gynecological patients in hospitals and provide the basis for scientific prevention and treatment. Methods The normal vaginal smear method was used to examine the vaginal discharge of 7376 gynecological clinics in Lulong County Hospitals from 2005 to 2008 so as to know the prevalence of Trichomonas vaginalis infection and to analyze the test results. Results The average infection rate of Trichomonas vaginalis in 4 years was 8.45% (623/7376). There was no significant difference in the annual infection rate, but it decreased year by year. The infection rate in the 35-year-old group was 11.78% (1491/1265) in 4 years, which was significantly higher In other age groups, the infection rate after the age of 40 was 11.49% (131/1140), but the infection rate in the 35-year-old group was 11.40% (39/342) in 2007, slightly lower than that of the 40-year-old group 11.80 (36/305). The lowest infection rate in the group under 20 years old was 0.90% (2/221). There was no significant difference in the seasonal infection rate. The infection rates in November, December and January were higher than those in other months, which were 9.15%, 8.94% and 9.88% respectively. Infection rate of rural residents (8.23%) was significantly higher than that of urban areas (1.17%). Conclusion The prevalence of Trichomonas vaginalis in the surveyed patients was higher than that of the global women (3.1%), lower than that of the same kind in the country. 35-45 years old was the highest incidence of Trichomonas vaginalis infection, Clearly affected.
