Many women discontinue their use of hormonal contraception, and even those who continue so may have difficulty using oral contraceptive pills consistently. New delivery systems, including the vaginal ring, may be easier to use, but user acceptability and satisfaction with these new methods may be affected by women's experience with their bodies.
Data for this study were collected as part of a randomized clinical trial on 201 women comparing immediate start of vaginal ring use with immediate start of low-dose oral contraceptive use. We assessed user satisfaction and method continuation 3 months after ring or pill initiation.
At 3 months, 174 of 201 subjects (87%) had follow-up interviews. Among the 174 study participants with follow-up data, 61% of ring subjects and 34% of pill subjects were very satisfied with their methods (p=.003). For posttrial contraception, 79% of ring subjects chose to continue with the ring whereas 59% of pill subjects chose to continue with the pill (p<.001). Women who reported greater comfort in touching their genitals, greater frequency of masturbation, more comfort with intercourse and past use of vaginal contraceptives and products were not more likely than others to be satisfied with the ring or to continue using it for birth control.
Women who were allocated to vaginal ring use, regardless of their baseline characteristics or behavior, were likely to be highly satisfied with the method and to continue its use.
许多女性会停止使用激素避孕法,即使是那些继续使用的女性,在持续服用口服避孕药时也可能会遇到困难。包括阴道环在内的新给药系统可能更易于使用,但这些新方法的用户接受度和满意度可能会受到女性身体体验的影响。
本研究的数据是作为一项随机临床试验的一部分收集的,该试验对201名女性进行了比较,一组立即开始使用阴道环,另一组立即开始使用低剂量口服避孕药。我们在开始使用阴道环或避孕药3个月后评估了用户满意度和方法持续性。
3个月时,201名受试者中有174名(87%)接受了随访访谈。在174名有随访数据的研究参与者中,61%的阴道环使用者和34%的口服避孕药使用者对其使用方法非常满意(p = 0.003)。对于试验后的避孕措施,79%的阴道环使用者选择继续使用阴道环,而59%的口服避孕药使用者选择继续使用避孕药(p < 0.001)。报告在触摸生殖器时更舒适、自慰频率更高、在性交时更舒适以及过去使用过阴道避孕法和产品的女性,并不比其他人更有可能对阴道环感到满意或继续使用它来避孕。
无论基线特征或行为如何,被分配使用阴道环的女性可能对该方法高度满意并继续使用。
