【目的】分析在本院就诊的月经过少病人的相关影响因素。【方法】使用统一问卷调查表，筛选出月经量过少的病人，同时从月经正常病人中选择和病例各种条件相当人群进行1∶2配对，进行病例对照研究。并对月经量过少的相关影响因素进行了单因素的基本分析和多因素 logistic回归分析。【结果】单因素分析显示：月经量过少与宫腔粘连、工作压力、人工流产两次及以上、作息不规律、婚姻生活不美满均存在相关性（P ＜00．1或00．5）。多因素非条件logistic回归分析结果显示：宫腔粘连、工作压力、人工流产、作息不规律与月经量过少成正相关（ P值分别为00．06、00．207、00．9、00．126）。【结论】宫腔粘连、工作压力、人工流产、作息不规律是月经量过少的危险因素。此为进一步的大样本多中心的流行病学的调查研究提供了理论依据。“,”Objective]To analyze the influencing factors of hypomenorrhea patients in our hospital .[Methods]Unified questionnaires were used to screen out patients with hypomenorrhea ,and patients with nor‐mal mestruation who had the same physical conditions were chosen and paired with hypomenorrhea at a ratio of 1 :2 .A case‐control study was conducted ,and single factor and multivariable logistic regression analyses were done .[Results]Single‐factor analysis showed that hypomenorrhea has correlation with intrauterine adhe‐sion ,stress at work ,abortion (over two times) ,irregular work and rest patterns ,and unsatisfactory marriage ( P <0 0.1 ,0 0.5 ,0 .05 ,0 .05 ,0 .01) .Multivariable non‐conditional logistic regression analysis showed that there was a positive correlation between hypomenorrhea with intrauterine adhesion ,stress at work ,abortion (over two times) ,and irregular work and rest patterns ( P =0 0.06 ,0 2.07 ,0 0.9 ,0 1.26)[.Conclusion]Intrau‐terine adhesion ,work stress ,abortion (over two times ) ,work and rest irregularity ,and unhappy marriage are all factors of hypomenorrhea .These factors have a certain correlation with hypomenorrhea ,and will be a theoretical foundation of further large sample and multi‐center epidemiological investigation .
