ABSTRACT
This study investigated contraceptive use during first sexual intercourse among 2.790 young men and women. The GRAVAD household survey in three Brazilian capital cities involved interviews in a probabilistic sample. A hierarchical logistic regression analysis was used. Variables grouped as: macro-social, socialization and sexual initiation, context of sexual initiation, and characteristics of the interviewee and his or her partner. The prevalence of contraceptive use was 68.3% for women and 65.3% for men. Among women, contraception use was associated to: per capita monthly family income, color/race, and the use of women's magazines as a source of information on pregnancy and contraception. For both genders, use was more frequent when partners discussed pregnancy prevention before intercourse, when sexual initiation was delayed and in a motel, and when the partner was patient. The interval between the start of the relationship and sexual initiation appeared associated to use during sexual initiation for men. Results suggest that macro-social factors determine more frequent contraception use during sexual initiation for women, while for men the relational context is more important.

Este estudo investigou o uso de contraceptivos na primeira relação sexual de 2.790 homens e mulheres. Trata-se de inquérito domiciliar em três capitais brasileiras, com entrevistas de amostra probabilística (Pesquisa GRAVAD). Utilizou-se análise de regressão logística. As variáveis foram agrupadas em: determinantes macrossociais, socialização e entrada na sexualidade, contexto da iniciação sexual e características da/o jovem e da/o parceira/o. A prevalência de foi de 68,3 por cento e de 65,3 por cento na dos homens. Entre elas, a contracepção associou-se à: renda familiar per capita, cor/raça e revistas femininas como fontes de informação sobre gravidez e contracepção. Para ambos os sexos, o uso foi mais freqüente quando houve conversa prévia sobre o tema entre parceiros, a iniciação sexual foi mais tardia e em motel, e o/a parceiro/a paciente. O tempo entre o início do relacionamento e a iniciação sexual mostrou-se associado ao uso na iniciação sexual dos rapazes. Fatores macrossociais parecem determinar a contracepção mais freqüente na iniciação sexual das mulheres, enquanto para os homens o contexto relacional é mais importante.
