The Contraceptive Health Research of Informed Choice Experience study involved 11 European countries with the goal of evaluating the influence of counseling on the user's choice among three different types of combined hormonal contraceptive (CHC) administration: pill, transdermal patch, and vaginal ring. Here, we report the results of the youngest age group (age 15-20 years) for Switzerland.
A total of 1,032 adolescent women who contemplated a CHC form of contraception were counseled about the three CHCs. Questionnaires were filled out to determine the women's preferred choice before and after counseling, and the reason for their final decision.
After counseling, more than one third of the women decided to use a different contraceptive method than initially intended. The fraction of vaginal ring users increased from 7.5% to 21.8%, and that of patch users from 3.3% to 5.8%. At pre-counseling, 225 women had no preconceived idea about which method to choose. Only 29 women were still undecided post-counseling. The main reasons adolescent women chose the vaginal ring or the patch were the monthly or weekly use and the ease of use.
Adolescent women's decision about which CHC to use is greatly influenced by counseling that provides balanced information on all CHCs.
知情选择经验研究避孕健康研究涉及 11 个欧洲国家，旨在评估咨询对三种不同类型组合激素避孕药（CHC）给药方式（药丸、透皮贴剂和阴道环）使用者选择的影响。在这里，我们报告了瑞士最年轻年龄组（15-20 岁）的结果。
共有 1032 名考虑使用 CHC 避孕的青春期女性接受了关于这三种 CHC 的咨询。在咨询前后填写问卷，以确定女性的首选选择以及最终决定的原因。
咨询后，超过三分之一的女性决定使用与最初意图不同的避孕方法。阴道环使用者的比例从 7.5%增加到 21.8%，贴剂使用者的比例从 3.3%增加到 5.8%。在咨询前，有 225 名女性对选择哪种方法没有先入为主的想法。咨询后只有 29 名女性仍未做出决定。青春期女性选择阴道环或贴剂的主要原因是每月或每周使用和使用方便。
咨询为所有 CHC 提供平衡信息，极大地影响了青春期女性选择使用哪种 CHC 的决定。
