Patterns of vaginal bleeding are an important factor in the acceptability of contraceptive methods. The analysis of data obtained from daily menstrual diary records is a major methodological problem to which no satisfactory solution exists. This review describes approaches to the analysis of bleeding patterns among contracepting and non-contracepting women and reviews the difficulties involved. The reference period method, introduced to avoid the arbitrary rules and definitions required for an analysis based on the concept of a menstrual cycle, is discussed and its limitations presented. The review draws on reports of meetings convened by the World Health Organization and the University of Exeter Family Planning Unit to discuss issues in the analysis. Previously unpublished methods are summarized and areas of controversy and topics for further research are identified.
阴道出血模式是影响避孕方法可接受性的一个重要因素。对每日月经日记记录所获数据进行分析是一个主要的方法学问题，目前尚无令人满意的解决方案。本综述描述了分析使用和未使用避孕措施女性出血模式的方法，并对其中涉及的困难进行了综述。文中讨论了为避免基于月经周期概念进行分析所需的任意规则和定义而引入的参考期方法，并阐述了其局限性。本综述借鉴了世界卫生组织和埃克塞特大学计划生育单位召开的会议报告，这些会议旨在讨论分析中的问题。文中总结了此前未发表的方法，确定了存在争议的领域和有待进一步研究的课题。
