BACKGROUND
Progestin-only contraceptive pills (POPs) offer a safe and effective contraceptive option, particularly for women at increased risk of venous thromboembolism. However, the prevalence of POP use among women in the United States is unknown.
STUDY DESIGN
We analyzed population-based data from 12,279 women aged 15-44 years in the National Survey of Family Growth. Data were collected continuously from 2006 to 2010 by in-person, computerized household interviews. Analyses describe POP use across sociodemographic and reproductive characteristics and thromboembolic risk profiles.
RESULTS
Overall, 0.4% of all reproductive-aged women in the United States currently use POPs. POP use was higher among parous, postpartum and breastfeeding women than their counterparts (all p values<.001). Women at higher risk of thromboembolism (older, obese, diabetic or smoking women) had similar proportions of POP use as women without those risks.
CONCLUSION
POPs are rarely used by US women. While data on chronic disease were limited, our results suggest that relatively few women with increased risk of thromboembolism are considering POPs when choosing an oral contraceptive.
背景
仅孕激素避孕药（POPs）为静脉血栓栓塞风险增加的女性提供了一种安全有效的避孕选择。然而，美国女性使用 POP 的流行率尚不清楚。
研究设计
我们分析了来自全国生育调查的 12279 名年龄在 15-44 岁的女性的基于人群的数据。数据通过面对面、计算机化的家庭访谈从 2006 年到 2010 年连续收集。分析描述了 POP 在社会人口学和生殖特征以及血栓栓塞风险特征中的使用情况。
结果
总体而言，美国所有育龄女性中，目前使用 POP 的比例为 0.4%。与对照组相比，多产、产后和哺乳期的女性使用 POP 的比例更高（所有 p 值均<.001）。血栓栓塞风险较高的女性（年龄较大、肥胖、糖尿病或吸烟的女性）与没有这些风险的女性使用 POP 的比例相似。
结论
美国女性很少使用 POPs。尽管关于慢性疾病的数据有限，但我们的结果表明，考虑到血栓栓塞风险增加，相对较少的女性在选择口服避孕药时会考虑使用 POPs。
