This paper examines contraceptive method use at different stages of the reproductive life course. Previous research on contraceptive practice in developed countries typically applies age as a proxy for reproductive history. While age is an essential and useful life course measure for understanding contraceptive use, investigations of contraceptive practice should also consider parity and fertility intentions, as they may be more accurate measures of reproductive life course stage. Analysis is based on data collected in the 2005 Household, Income and Labour Dynamics in Australia (HILDA) survey, a nationally representative sample of women of reproductive age (18-44). For women at risk of pregnancy, the most commonly used methods are easily reversed methods such as the oral contraceptive pill (30%) and condom (23%), medium-term methods such as the intrauterine device and implantation (5%) and permanent methods (7% tubal ligation and 9% vasectomy of partner). Logistic regression models are used to investigate the use of four popular contraceptive methods by parity, age and fertility intentions controlling for socio-demographic factors. The main findings indicate that the use of these methods varies substantially by the stage of a woman's reproductive life course: age, parity and fertility intentions are all associated with method use.
本文探讨了在生殖生命历程的不同阶段使用避孕方法的情况。先前对发达国家避孕实践的研究通常将年龄作为生殖史的代表。虽然年龄是理解避孕使用的基本和有用的生命历程衡量标准，但对避孕实践的调查也应考虑生育力和生育意愿，因为它们可能是生殖生命历程阶段的更准确衡量标准。分析基于在澳大利亚家庭、收入和劳动力动态调查（HILDA）中收集的数据，该调查是具有代表性的育龄妇女（18-44 岁）的样本。对于有怀孕风险的女性，最常用的方法是容易逆转的方法，如口服避孕药（30%）和避孕套（23%），中期方法如宫内节育器和植入物（5%）和永久性方法（7%输卵管结扎和 9%伴侣输精管切除术）。逻辑回归模型用于调查在控制社会人口因素的情况下，按生育力、年龄和生育意愿使用四种流行避孕方法的情况。主要发现表明，这些方法的使用情况在女性生殖生命历程的各个阶段有很大差异：年龄、生育力和生育意愿都与方法的使用有关。
