Anemia, particularly if mild, is ignored frequently. We conducted a questionnaire survey of 252 physicians and medical students to verify this impression and to explore the reasons for it. A cumulative 40% to 57% depending on the hypothetical patients' circumstances) of respondents chose to investigate anemia only at hemoglobin levels too low for the accepted criteria in female patients; a striking 78% to 89% did so in male patients. Only 54% and 30% knew the correct textbook definition of anemia for women and men, respectively. More importantly, 35% to 60% demonstrated criteria for choosing to investigate anemia were lower than even their own perception of the textbook definition. Little difference existed among the various physician subgroups in their responses. The discrepancy between what physicians do and what they are taught appears to arise from several factors, of which lack of knowledge is only one.
贫血，尤其是轻度贫血，常常被忽视。我们对252名医生和医学生进行了问卷调查，以证实这一印象并探究其原因。根据假设患者的情况，累计有40%至57%的受访者选择仅在女性患者血红蛋白水平低于公认标准时才对贫血进行调查；在男性患者中，这一比例高达78%至89%。分别只有54%和30%的人知道教科书上对女性和男性贫血的正确定义。更重要的是，35%至60%的人表明选择调查贫血的标准甚至低于他们自己对教科书定义的理解。不同医生亚组的回答差异不大。医生的实际做法与所学内容之间的差异似乎源于几个因素，其中知识匮乏只是其中之一。
