Examining women's reproductive experiences over time reveals a more dynamic view of women's behaviors and needs than current status measures alone. This study uses sequence and cluster analyses, which are designed for identifying patterns and subgroups in longitudinal data. We apply these methods to contraceptive calendar data in Burundi to identify discrete clusters of women based on contraceptive and pregnancy behaviors over the past 5 years. We identify six unique clusters; three characterized by no use of contraception (85 percent of women) and three by use (16 percent). The Quiet Calendar cluster (42 percent) comprise women who neither experience pregnancy nor use contraception. Family Builder 1 (25 percent) and 2 (18 percent) both include women who experience two pregnancies, but differ in unmet need and lifetime experience with contraception. Modern Mother (8 percent), Consistently Covered Mother (6 percent), and Traditional Mother (2 percent) clusters differ by type of contraception used following pregnancy. Factors associated with cluster membership are need for family planning, lifetime experience with contraception, marital status, pregnancy intention, and age. This clustering approach provides a new, more holistic way to measure the diverse needs across unique subpopulations and can inform the development of multifaceted, adaptable strategies to meet women's dynamic fertility needs over the reproductive life course.

布隆迪避孕药具组的人口和生育特征

随着时间的推移检查女性的生殖经历揭示了对女性行为和需求的更动态的看法，而不是单独的现状测量。本研究使用序列和聚类分析，旨在识别纵向数据中的模式和亚组。我们将这些方法应用于布隆迪的避孕日历数据，以根据过去 5 年的避孕和怀孕行为识别离散的女性群体。我们确定了六个独特的集群；三个特点是不使用避孕措施（85% 的女性），三个是使用避孕措施（16%）。安静日历组（42%）包括既没有怀孕也没有使用避孕措施的女性。家庭建设者 1（25%）和 2（18%）都包括经历过两次怀孕的女性，但在未满足的需求和避孕方面的终生体验方面有所不同。现代母亲 (8%)、持续覆盖母亲 (6%) 和传统母亲 (2%) 集群因怀孕后使用的避孕类型而异。与集群成员相关的因素是计划生育的需要、避孕的终生经历、婚姻状况、怀孕意图和年龄。这种聚类方法提供了一种新的、更全面的方法来衡量独特亚群的多样化需求，并可以为制定多方面、适应性强的战略提供信息，以满足女性在生殖生命过程中的动态生育需求。与集群成员相关的因素是计划生育的需要、避孕的终生经历、婚姻状况、怀孕意图和年龄。这种聚类方法提供了一种新的、更全面的方法来衡量独特亚群的多样化需求，并可以为制定多方面、适应性强的战略提供信息，以满足女性在生殖生命过程中的动态生育需求。与集群成员相关的因素是计划生育的需要、避孕的终生经历、婚姻状况、怀孕意图和年龄。这种聚类方法提供了一种新的、更全面的方法来衡量独特亚群的多样化需求，并可以为制定多方面、适应性强的战略提供信息，以满足女性在生殖生命过程中的动态生育需求。
