This study examined the influence of the relationship context where adolescent sexual activity takes place on contraceptive decisions. The data were collected in a specially designed survey carried out in May 2000 on 1,438 adolescent males aged 13-19 residing in favelas (urban slum areas) of Recife, Brazil. A logistic regression analysis of condom use at last sexual intercourse and a multinomial logit analysis of contraceptive method choice were performed for 678 sexually active adolescents. Educational attainment, degree of knowledge of HIV transmission and prevention, and condom use at first sexual intercourse were found to be significantly associated with current condom use. Regarding the relationship context, the analysis revealed that adolescent males in steady relationships were less likely to use condoms, less likely to regard themselves at risk of HIV infection, and more concerned about pregnancy prevention than adolescents in casual relationships. Differentials in condom use by type of relationship, however, did not result from a higher rejection of contraception by steady partners but from their higher likelihood to rely on other contraceptive methods. Results suggest that prevention campaigns need to take into account the intimate context where adolescents assess potential health risks, and to address the divergent symbolic meanings condoms may have in different types of relationships. If an increase of condom use among stable sexual partners is pursued, public health campaigns might need to romanticize condom use as a sign of love and trust and place more emphasis on the benefits of dual protection.
本研究考察了青少年进行性活动的关系背景对避孕决策的影响。数据收集于2000年5月开展的一项专门设计的调查,调查对象为居住在巴西累西腓贫民窟的1438名13 - 19岁的青少年男性。对678名有性行为的青少年进行了末次性交时使用避孕套的逻辑回归分析以及避孕方法选择的多项逻辑回归分析。研究发现,受教育程度、对艾滋病毒传播与预防的了解程度以及初次性交时使用避孕套的情况与当前使用避孕套显著相关。关于关系背景,分析显示,处于稳定关系中的青少年男性比处于随意关系中的青少年男性使用避孕套的可能性更低,认为自己感染艾滋病毒风险更低,且更关注预防怀孕。然而,不同关系类型在避孕套使用上的差异并非源于稳定伴侣对避孕更高的排斥,而是源于他们更有可能依赖其他避孕方法。结果表明,预防宣传活动需要考虑青少年评估潜在健康风险的亲密背景,并应对避孕套在不同关系类型中可能具有的不同象征意义。如果要提高稳定的性伴侣之间避孕套的使用比例,公共卫生宣传活动可能需要将避孕套的使用浪漫化为爱与信任的象征,并更加强调双重保护的益处。
