Objective To understand the status of anemia in pregnant women and the risk factors causing the diseas in pregnant women .Method A retrospective analysis was firstly conducted into the clinical data of 500 pregnant women suffering from anemia .The clinical data of 82 cases of pregnant women ( the experimental group ) and the data of pregnant women without anemia ( the control group ) were then compared and the possible risk factors were analyzed .Findings Of the 82 patients of anemia , 16 were found to suffer mild anemia .43 were found to have moderate anemia .13 were cases severe anemia.Significant difference was found in the degree of anemia between patients of different location of residence and education level.The difference was significant (P<0.05).The women who experienced 3 or more than times of abortion, whose age at menarche was <14 years old (modified), who often stayed up at night, and who had heavy economic burden are more likely to suffer anemia (P<0.05).Conclusion Women living in the relatively small cities and having higher education level are less likely to suffer anemia while those who had over 3 times of abortion , were at young age of menarche , often stayed up late at night , and had heavy economic are more likely to have anemia .%目的：了解孕妇贫血状况并分析孕妇贫血影响因素。方法回顾分析500例孕妇的临床资料，观察比较出现贫血的82例孕妇（观察组）与未出现贫血孕妇（对照组）的资料，分析孕妇贫血的危险因素。结果82例贫血孕妇中，轻度贫血16例，中度贫血44例，重度贫血22例。不同居住地、不同文化程度的孕妇间贫血状况差异显著（均P＜0．05）；流产次数≥3次、月经初潮年龄＜14岁、经常熬夜、存在经济负担的孕妇出现贫血的概率显著增加（P＜0．05）。结论居住在城市及文化程度较高的孕妇出现贫血的相对较少，流产次数多、月经初潮年龄小、经常熬夜以及有经济负担的孕妇出现贫血的可能性较大。
