NuvaRing is a combined contraceptive vaginal ring that releases constant low doses of ethinylestradiol and etonogestrel. One cycle consists of 3 weeks of ring use followed by a 1-week ring-free period and the ring can easily be inserted and removed by the women themselves. Acceptability and satisfaction were determined by a questionnaire in two large, multicenter, open, 1-year studies conducted in a total of 2393 women, of whom 1950 (82%) completed cycle 3 questionnaires. Overall, 53% of participants switched to NuvaRing from other hormonal contraception; the main reason given for deciding to use NuvaRing (47%) was that it appeared to be a new and attractive method of contraception. Nearly all users considered the ring easy to insert and remove. Although 15% of women and 30% of their partners reported feeling the ring at least occasionally during intercourse, very few partners objected to women using the ring and the majority of women felt comfortable with it during intercourse. Reductions in menstrual pain and the length of the menstrual period were reported during ring use. More than 90% of women were satisfied or very satisfied with the ring at each assessment and 97% of those who completed the studies said they would recommend the method to others. At baseline, the preferred contraceptive method was the pill (66% of users). However, more than 80% of women at each assessment said they would use NuvaRing as their first-choice method. High satisfaction at cycle 3 was a good predictor of low subsequent discontinuation risk. In conclusion, this analysis shows that users express good acceptability and a high level of satisfaction with NuvaRing.
优思明阴道环是一种复方避孕阴道环,可持续释放低剂量的炔雌醇和依托孕烯。一个周期包括使用阴道环3周,随后是1周的无环期,女性可自行轻松插入和取出阴道环。在两项大型、多中心、开放性的为期1年的研究中,通过问卷调查确定了2393名女性的接受度和满意度,其中1950名(82%)完成了第3周期问卷。总体而言,53%的参与者从其他激素避孕方法改用优思明阴道环;决定使用优思明阴道环的主要原因(47%)是它似乎是一种新颖且有吸引力的避孕方法。几乎所有使用者都认为阴道环易于插入和取出。虽然15%的女性及其30%的伴侣报告在性交时至少偶尔能感觉到阴道环,但很少有伴侣反对女性使用阴道环,且大多数女性在性交时对此感到舒适。据报告,使用阴道环期间月经疼痛和经期长度有所减轻。在每次评估中,超过90%的女性对阴道环感到满意或非常满意,97%完成研究的女性表示会向他人推荐这种方法。基线时,首选的避孕方法是口服避孕药(66%的使用者)。然而,在每次评估中,超过80%的女性表示会将优思明阴道环作为首选方法。第3周期的高满意度是后续停用风险低的良好预测指标。总之,该分析表明使用者对优思明阴道环表现出良好的接受度和高度满意度。
