Objective:To understand the correlation between the rate of vaginal infection and their age as well as seasonal change of Datong district in Shanxi,and further to provide reference for clinical prevention and treatment. Method:The examination materials of 5368 vaginal secretions in the department of gynaecology from April 2013 to March 2014 were retrospectively analyzed,and the testing results and the correlation between age and season were comprehensive analyzed.Result:Among 5368 vaginal secretions,the most cases of cleanness Ⅲ-Ⅳ degree of vagina in patients between 20 and 30 years were detected,and the cleanliness detection rate (Ⅲ and Ⅳ) of samples in autumn were significantly higher than those in other seasons(P<0.05).The detection rate of trichomonas vaginitis in patients below 40 years were significantly higher than those in above 40 years.The detection rate of fungal vaginitis(12.4%) and clue cells (23.4%) in patients between 40 and 50 years were significantly higher than those in other groups(P<0.05). The occurrence of trichomonas vaginitis was significantly lower than that of candida vaginitis and bacterial vaginitis,fungal vaginitis detection rate was lower than the bacterial vaginitis(P<0.05).The detection rate of trichomonas vaginitis in summer and autumn were significantly higher than that in spring and winter,and the detection rate of candida vaginitis in summer and clue cells in winter were significantly higher than those in any other seasons(P<0.05).With the increasing degree of vaginal secretions,the detection rate of trichomonas vaginitis and fungal vaginitis increased.The detection rate of the pathogen was significantly higher in abnormal cleanness degree samples (16.7%) than that of cleanliness grade Ⅰ toⅡ specimens(2.7%) from female vaginal secretion(P<0.05).And the detection rate of clue cell in the cleanness Ⅲ degree of vagina specimen was significantly higher than that of others(P<0.05).Conclusion:The detection rate of female trichomonas vaginitis is significantly lower than that of either fungal vaginitis and bacterial vaginosis in the area of Datong,which may be related to the ages and local weather.%目的：了解山西大同地区女性阴道炎病原体的感染率与年龄和季节性的关系，为临床预防和治疗提供参考。方法：回顾性分析2013年2月-2014年1月在本院妇科就诊的患者阴道分泌物检查资料5368份，并综合分析检测结果与年龄和季节相关性。结果：在5368份送检样本中，20~30岁患者阴道分泌物Ⅲ~Ⅳ度异常检出率最高，秋季清洁度Ⅲ和Ⅳ度检出率均明显高于其他季节（P<0.05）。40岁以下患者滴虫性阴道炎检出率明显高于40岁以上各年龄组；40~50岁年龄组真菌性阴道炎检出率（12.4%）和线索细胞检出率（23.4%）均明显高于其他年龄组（P<0.05）。女性滴虫性阴道炎检出率明显低于真菌性阴道炎和细菌性阴道炎，真菌性阴道炎的检出率低于细菌性阴道炎（P<0.05）；夏季和秋季滴虫性阴道炎检出率明显高于春季和冬季（P<0.05）；夏季真菌性阴道炎和冬季线索细胞的检出率均高于其他季节（P<0.05）。随着阴道分泌物清洁度度数的增加，滴虫性阴道炎和真菌性阴道炎的检出率呈明显递增趋势。女性阴道分泌物清洁度异常标本中病原体的检出率（16.7%）明显高于清洁度Ⅰ~Ⅱ度标本（2.7%）（P<0.05）；阴道分泌物清洁度Ⅲ度的标本中线索细胞的检出率明显高于其他清洁度度数的标本（P<0.05）。结论：本地区女性滴虫性阴道炎检出率明显低于真菌性阴道炎和细菌性阴道炎，可能与患者年龄和当地气候条件有关。
