Purpose. To identify correlates of combined hormonal contraception and condom use (dual method use) compared with no methods, condoms only or hormonal contraception only. Data are from a baseline assessment of 335 youth (52% female) enrolled in an intervention trial. Multinomial logistic regression identified theory-based factors associated with dual method use. At last intercourse 47% of respondents used dual methods, 29% condom only, 14% hormonal contraception only, and 10% no methods. No method users were less likely than dual-method users to feel "dirty" about pregnancy, to have ask about historical condom use, to have more than two partners, to view condom use as normative for boys and more likely to perceive pregnancy risk as remote. Hormonal-contraception-only users were more likely to have sex weekly and perceive sex as pleasurable for girls, and less likely to view condom use as normative for boys and to ask a partner to use a condom. Condom-only users were more likely to perceive pregnancy chance as remote, and less likely to have more than two partners and to want peers to think they were virgins. Interventions should include benefits of dual methods while counseling about the negative impact of STI and unplanned teen pregnancy.
目的。确定与未采取任何避孕措施、仅使用避孕套或仅使用激素避孕法相比,联合使用激素避孕法和避孕套(双重避孕法)的相关因素。数据来自一项干预试验中335名青少年(52%为女性)的基线评估。多项逻辑回归分析确定了与双重避孕法使用相关的基于理论的因素。在最后一次性交时,47%的受访者使用双重避孕法,29%仅使用避孕套,14%仅使用激素避孕法,10%未采取任何避孕措施。未采取任何避孕措施的使用者相较于双重避孕法使用者,对怀孕感到“肮脏”的可能性更低,询问性伴侣过去使用避孕套情况的可能性更低,拥有两个以上性伴侣的可能性更低,认为男孩使用避孕套是常态的可能性更低,且更可能认为怀孕风险很低。仅使用激素避孕法的使用者更可能每周发生性行为,且认为女孩性行为是愉悦的,认为男孩使用避孕套是常态以及要求性伴侣使用避孕套的可能性更低。仅使用避孕套的使用者更可能认为怀孕几率很低,拥有两个以上性伴侣以及希望同龄人认为自己是处女的可能性更低。干预措施应在咨询性传播感染和意外青少年怀孕的负面影响时,纳入双重避孕法的益处。
