To describe women's condom use and assess predictors of consistent condom use and dual method use in the 6 months after the initiation of oral contraception (OC).
We conducted a planned secondary cohort analysis among women less than 25 years of age initiating oral contraceptives at public family planning clinics in Atlanta, Dallas and New York City, USA, as part of a randomized trial. These clinics provide care to predominantly African American or Hispanic women of low socioeconomic status. Participants completed interviews at enrollment and at 6 months after OC start. We used multivariate logistic regression to assess factors associated with consistent condom and dual method use at 6 months.
1281 participants met the inclusion criteria for this analysis. At enrollment prior to OC start, 28% were consistent condom users. In the six months after initiation of oral contraception, only 14% always used a condom and 4% always used dual methods. In multivariate analysis, receiving basic advice to always use a condom after OC initiation from a provider during the baseline clinic consultation was associated with a 50% increase in the odds of using condoms consistently. Only 28% of participants were given this condom use advice.
This study documents a decline in women's condom consistent use subsequent to initiation of the oral contraceptive and suggests that opportunities for positive intervention around condom use among women starting hormonal methods are being missed. Basic condom use advice, which is neither time consuming nor resource dependent, was associated with increased consistent use and should be immediately implemented in all family planning services.
描述女性避孕套的使用情况,并评估口服避孕药(OC)开始使用后6个月内持续使用避孕套和双重避孕方法使用的预测因素。
作为一项随机试验的一部分,我们在美国亚特兰大、达拉斯和纽约市的公共计划生育诊所,对开始使用口服避孕药的25岁以下女性进行了一项计划中的二次队列分析。这些诊所主要为社会经济地位较低的非裔美国女性或西班牙裔女性提供护理。参与者在入组时和开始使用OC后6个月完成访谈。我们使用多变量逻辑回归来评估与6个月时持续使用避孕套和双重避孕方法相关的因素。
1281名参与者符合本分析的纳入标准。在开始使用OC之前的入组时,28%为持续使用避孕套者。在开始口服避孕药后的6个月内,只有14%的人始终使用避孕套,4%的人始终使用双重避孕方法。在多变量分析中,在基线诊所咨询期间从提供者那里获得在开始使用OC后始终使用避孕套的基本建议,与持续使用避孕套的几率增加50%相关。只有28%的参与者得到了这种避孕套使用建议。
本研究记录了口服避孕药开始使用后女性持续使用避孕套的情况下降,并表明在开始使用激素避孕方法的女性中,围绕避孕套使用进行积极干预的机会正在被错过。基本的避孕套使用建议既不耗时也不依赖资源,与增加持续使用相关,应立即在所有计划生育服务中实施。
