Contraceptive efficacy and side effects are primary concerns of women when choosing a contraceptive method.
This cross-sectional multicenter study was designed to assess the reasons for selecting the contraceptive pill, the skin patch or the vaginal ring in 9700 women, aged 18-49 years, who consulted their doctors for starting or re-initiating combined hormonal contraception. A self-administered questionnaire regarding the reasons for the selection made and for the refusal of the remaining two methods was completed.
The vaginal ring showed the highest acceptance (46%) compared with the pill (39%) and the skin patch (15%), particularly in women aged 35-39 years. The ring and the skin patch were mainly preferred because of the lower probability of inadvertent omission (62% of cases), convenience, and monthly or weekly frequency of use. The pill was preferred because of its proven efficacy (60% of cases) and ease of use. The acceptance of the skin patch increased with age and the pill was mostly accepted only by women in the youngest age groups.
Convenience, frequency of use and lower probability of inadvertent omission were the primary determinants of contraceptive choice rather than the women's profile.
避孕效果和副作用是女性选择避孕方法时的主要关注点。
这项横断面多中心研究旨在评估9700名年龄在18至49岁之间、因开始或重新采用复方激素避孕而咨询医生的女性选择避孕药、皮肤贴片或阴道环的原因。完成了一份关于选择原因以及拒绝其余两种方法原因的自填式问卷。
与避孕药（39%）和皮肤贴片（15%）相比，阴道环的接受度最高（46%），在35至39岁的女性中尤为明显。阴道环和皮肤贴片主要因其意外漏用的可能性较低（62%的情况）、便利性以及每月或每周的使用频率而更受青睐。避孕药因其已证实的效果（60%的情况）和易用性而更受青睐。皮肤贴片的接受度随年龄增长而增加，而避孕药大多仅被最年轻年龄组的女性接受。
便利性、使用频率和意外漏用的低可能性是避孕选择的主要决定因素，而非女性的特征。
