摘　　要：通过对女大学生“饮食紊乱”发生状况的调研，了解女大学生饮食紊乱发病比率及特征，探讨女大学生饮食紊乱对月经及骨量的影响作用特点。在北京市8所高校女大学生发放饮食情况调查问卷，按照受试者纳入标准，选取187名女大学生，进行月经情况问诊及骨密度（姻）测定。结果发现：受试者EDI问卷结果显示32人出现明显饮食紊乱（DE），占总人数17．1％。EDI-3RF分量表得分比较，求瘦倾向（DT）和不满体型（BD）分值表现为单纯饮食紊乱、饮食紊乱伴月经紊乱、饮食紊乱伴骨量降低，受试者均高于总受试人群（P〈0．01～0．05）。饮食紊乱受试者月经过少或闭经的发病率是无饮食紊乱受试者的2倍左右。骨量降低受试者EDI平均得分显著增高（P〈0．01）；而饮食紊乱伴骨量降低受试者L2—4的BMD显著降低（P〈0．05）。Pearson相关分析，EDl分值与L2-4及PFR的BMD均呈显著正相关（P〈0．05）。结论表明：北京市女大学生受试者“饮食紊乱”发病率较高，女大学生饮食紊乱的发病特征以求瘦倾向和不满体型为主要表现。饮食紊乱可能主要通过干扰机体能量获得及月经周期而影响骨量。This study aims to investigate the prevalence of the dieting disorder in female college students in Beijing, to understand the features of the dieting disorder,and to explore the relationship between dieting disorder,menstruation and BMD. Methods： The 187 subjects are drawn from 8 universities in Beijing by random sampling. Questionnaires on dieting status analysis are adopted （EDI3） in the research. Diagnosis of Menstrual Irregularity （MI） is done by gynecologists, and BMD is measured by DXA （GE, USA）. Re suits： The questionnaires show that 32 subjects exhibit significant dieting disorder, accounting for t7.1 of the total number. EDI-3 RF score of subjects show that the drive for thinness （DT） and body dissatis- faction （BD） score all increase in dieting disorder （DE）, DE with MI, and DE with Low Bone Mass （LBM） （P〈0. 01-0. 05）. The incidences of oligomenorrhea and amenorrhea in DE double what they are in NDE. EDI score elevates in LBM （P〈0.01）. BMD of L2-4 decreases in DE with LBM （P〈0. 05）. EDI score has negative correlation with BMD of L2-4 and PFR （P〈0. 05）. Conclusion： There is higher prevalence of dieting disorder in this study, which mainly show the DT and BD, and may be disturbed bone mass by Energy gain and menstrual cycle change.
