背景：月经出血持续时间和量的人群差异在文献中很少受到关注。本研究描述了这些特点，并调查了自我感知的月经出血量的分布，根据社会人口统计学，行为，和生殖characteristics.Methods：一个基于社区的横断面研究进行了18-45岁的妇女用户的31初级卫生保健（PHC）设施在佩尔蒂尼奥市（巴西）。在两个工作班次的候诊室进行结构式问卷调查。月经出血的严重程度是通过对以下问题的回答来确定的：“通常你在每次月经中失血多少？“通过泊松回归进行的粗分析和调整分析考虑了每个PHC设施的聚集性。结果：共有865名妇女入选。月经量过多的发生率为35.3%（95% CI 32.1-38.6%）。在调整后的分析中，在年龄较大，受教育程度较低和肥胖的女性中，月经大量出血的比例较高，怀孕次数较多，并且报告月经期较长，月经期外出血和血液中有血块。使用激素避孕方法是保护对重menuses.Conclusion：月经大出血是非常普遍的，在社区一级，并与社会人口和人体测量妇女的特点，以及月经持续时间，额外的出血和血栓的存在。
Background: Population variation in the duration and amount of menstrual bleeding has received little attention in the literature. This study describes these characteristics and investigates the distribution of self-perceived amount of menstrual bleeding according to socio-demographic, behavioral, and reproductive characteristics.Methods: A community-based cross-sectional study was conducted among 18-45 years old women users of the 31 primary health care (PHC) facilities in Pelotas city (Brazil). Interviews with structured questionnaire were carried out in the waiting rooms during two work shifts. Heaviness of menstrual bleeding was determined through the answer to the question: "Usually how much blood do you lose in every period?" Crude and adjusted analyses through Poisson regression took into account the aggregation per PHC facility.Results: A total of 865 women were enrolled. Prevalence of heavy menstrual flow was 35.3% (95% CI 32.1-38.6%). In adjusted analyses, heavy menstrual bleeding was higher among the older, less educated and obese women, with higher number of pregnancies and who reported longer menstrual periods, extra-menstrual bleeding and clots in the flow. Use of hormonal contraceptive methods was protective against heavy menses.Conclusion: Heavy menstrual bleeding is highly prevalent at the community level, and is associated with socio-demographic and anthropometric women's characteristics, as well as with duration of menstruation, extra-bleeding and presence of clots.
