BACKGROUND
This longitudinal analysis examines how patterns of contraceptive use changed over 11 years among Australian women born between 1973 and 1978.
STUDY DESIGN
The analysis included 6708 women sampled from the Australian universal health insurance database who completed four self-report postal surveys between 1996 and 2006. Change over time in use of any method of contraception and the common single methods of the oral contraceptive pill and condom was examined using a longitudinal logistic regression model.
RESULTS
The oral contraceptive pill was the most commonly used single method at each survey (27-44%) but decreased over time. Over time, contraceptive users were increasingly more likely to be single or in a de facto relationship or to have had two or more births.
CONCLUSIONS
Women's contraceptive use and the factors associated with contraceptive use change over time as women move into relationships, try to conceive, have babies and complete their families.
背景
本纵向分析考察了 1973 年至 1978 年间出生的澳大利亚女性在 11 年内避孕药具使用模式的变化。
研究设计
该分析包括了从澳大利亚全民健康保险数据库中抽取的 6708 名女性，她们在 1996 年至 2006 年间完成了四次邮政问卷调查。使用纵向逻辑回归模型，研究了在任何避孕方法和常见的单一方法（口服避孕药和避孕套）的使用随时间的变化。
结果
口服避孕药在每个调查中都是最常用的单一方法（27-44%），但随着时间的推移逐渐减少。随着时间的推移，避孕药具使用者越来越可能是单身或事实婚姻关系，或者已经有两个或更多的孩子。
结论
随着女性进入关系、尝试怀孕、生育和完成家庭，她们的避孕方法使用和与避孕方法使用相关的因素会随着时间的推移而发生变化。
