To characterize factors associated with dual method contraceptive use in a sample of adolescent women. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: We conducted a cross-sectional survey of sexually active African American women aged 14-19 years who attended an urban Title X clinic in Georgia in 2012 (N = 350). Participants completed a computerized survey to assess contraceptive and condom use during the past 2 sexual encounters with their most recent partner. Dual method use was defined as use of a hormonal contraceptive or intrauterine device and a condom. We applied multinomial logistic regression, using generalized estimating equations, to examine the adjusted association between dual method use (vs use of no methods or less effective methods alone; eg, withdrawal) and select characteristics.
Dual methods were used by 20.6% of participants at last sexual intercourse and 23.6% at next to last sexual intercourse. Having a previous sexually transmitted disease (adjusted odds ratio [aOR], 2.30; 95% confidence interval [CI], 1.26-4.18), negative attitude toward pregnancy (aOR, 2.25; 95% CI, 1.19-4.28), and a mother who gave birth as a teen (aOR, 2.34; 95% CI, 1.21-4.52) were associated with higher odds of dual method use. Having no health insurance (aOR, 0.39; 95% CI, 0.18-0.82), 4 or more lifetime sexual partners (aOR, 0.42; 95% CI, 0.22-0.78), sex at least weekly (aOR, 0.54; 95% CI, 0.29-0.99), and agreeing to monogamy with the most recent partner (aOR, 0.40; 95% CI, 0.16-0.96) were associated with decreased odds of dual method use.
Dual method use was uncommon in our sample. Efforts to increase use of dual methods should address individual and relationship factors.
在一组青春期女性样本中,确定与同时采用两种避孕方法相关的因素。
设计、地点、参与者、干预措施及主要结局指标:我们对2012年在佐治亚州一家城市第十类诊所就诊的14 - 19岁有性行为的非裔美国女性进行了一项横断面调查(N = 350)。参与者完成了一项计算机化调查,以评估在过去与最近性伴侣的两次性接触中避孕措施和避孕套的使用情况。同时采用两种方法被定义为使用激素避孕法或宫内节育器以及避孕套。我们应用多项逻辑回归,使用广义估计方程,来检验同时采用两种方法(与不采用任何方法或仅采用效果较差的方法,如体外射精相比)与选定特征之间的校正关联。
在最后一次性交中,20.6%的参与者同时采用了两种方法,在倒数第二次性交中这一比例为23.6%。既往患有性传播疾病(校正比值比[aOR],2.30;95%置信区间[CI],1.26 - 4.18)、对怀孕持消极态度(aOR,2.25;95% CI,1.19 - 4.28)以及母亲在青少年时期生育(aOR,2.34;95% CI,1.21 - 4.52)与同时采用两种方法的较高几率相关。没有医疗保险(aOR,0.39;95% CI,0.18 - 0.82)、一生中有4个或更多性伴侣(aOR,0.42;95% CI,0.22 - 0.78)、至少每周进行一次性行为(aOR,0.54;95% CI,0.29 - 0.99)以及同意与最近的性伴侣保持一夫一妻制(aOR,0.40;95% CI,0.16 - 0.96)与同时采用两种方法的几率降低相关。
在我们的样本中,同时采用两种方法的情况并不常见。增加同时采用两种方法的努力应针对个体和关系因素。
