To estimate the prevalence of and factors associated with dual method use (i.e., condom with hormonal contraception or an intrauterine device) among adolescents and young women in the United States.
We used 2006-2010 National Survey of Family Growth data from 2,093 unmarried females aged 15-24 years and at risk for unintended pregnancy. Using multivariable logistic regression, we estimated adjusted odds ratios (aORs) and 95% confidence intervals (CIs) to assess the associations between dual method use at last sex and sociodemographic, behavioral, reproductive history, and sexual behavior factors.
At last sex, 20.7% of adolescents and young women used dual methods, 34.4% used condoms alone, 29.1% used hormonal contraception or an intrauterine device alone, and 15.8% used another method or no method. Factors associated with decreased odds of dual method use versus dual method nonuse included having a previous pregnancy (aOR = .44, 95% CI .27-.69), not having health insurance coverage over the past 12 months (aOR = .41, 95% CI .19-.91), and having sex prior to age 16 (aOR = .49, 95% CI .30-.78).
The prevalence of dual method use is low among adolescents and young women. Adolescents and young women who may have a higher risk of pregnancy and sexually transmitted infections (e.g., those with a previous pregnancy) were less likely to use dual methods at last sex. Interventions are needed to increase the correct and consistent use of dual methods among adolescents and young women who may be at greater risk for unintended pregnancy and sexually transmitted infections.
评估美国青少年及年轻女性中双重避孕方法（即避孕套与激素避孕法或宫内节育器联用）的使用情况及相关因素。
我们使用了2006 - 2010年全国家庭成长调查数据，该数据来自2093名年龄在15 - 24岁、有意外怀孕风险的未婚女性。通过多变量逻辑回归，我们估计了调整后的优势比（aORs）和95%置信区间（CIs），以评估上次性行为时使用双重避孕方法与社会人口统计学、行为、生殖史及性行为因素之间的关联。
在上次性行为时，20.7%的青少年及年轻女性使用了双重避孕方法，34.4%仅使用避孕套，29.1%仅使用激素避孕法或宫内节育器，15.8%使用了其他方法或未采取任何避孕措施。与未使用双重避孕方法相比，使用双重避孕方法几率降低的相关因素包括曾有过怀孕经历（aOR = 0.44，95% CI 0.27 - 0.69）、在过去12个月内未参加医疗保险（aOR = 0.41，95% CI 0.19 - 0.91）以及在16岁之前开始性行为（aOR = 0.49，95% CI 0.30 - 0.78）。
青少年及年轻女性中双重避孕方法的使用率较低。怀孕及性传播感染风险可能较高的青少年及年轻女性（如曾有过怀孕经历者）在上次性行为时使用双重避孕方法的可能性较小。对于意外怀孕及性传播感染风险可能更高的青少年及年轻女性，需要采取干预措施以提高其对双重避孕方法的正确和持续使用。
