[Intimate partner sexual violence among men and women in urban Brazil, 2005].

OBJECTIVE To estimate the prevalence of intimate partner sexual violence among men and women of the Brazilian urban population and factors associated to it. METHODS The data analyzed is part of the study conducted between 1998 and 2005 among urban populations in Brazil. The data was obtained by means of a questionnaire applied to a representative sample of 5.040 individuals, men and women 16 to 65 years of age. Descriptive analysis was undertaken with weighted data, utilizing F design-based tests, with 5% significance. RESULTS The global prevalence of intimate partner sexual violence was 8.6%, being predominant among women (11.8% versus 5.1%). Women consistently reported higher rates of violence then men, except in cases involving homo/bisexual partners. The rate verified for male homo/bisexuals was significantly greater than that found among male heterosexuals, but this difference in rates was not significant among women. The black population, irrespective of sex, referred more violence than the white population. The lower the income and years of formal education, the greater the rates of violence. However, men from poorer regions referred more violence, but this did not occur with respect to women. Diverse situations with respect to work, use of condoms, lower age at first intercourse and number of partners during the last five years differed significantly among women, but not among men. For both men and women sexual violence was associated with being separated or divorced, having had STDs, self -evaluation of being at risk for HIV, but was not associated with testing positive for HIV. CONCLUSIONS The high magnitude of sexual violence as well as female surtax is confirmed. Violence as a result of gender conflicts, that pervades social stratification and ethnic groups is reiterated. As to the Aids epidemic, sexual violence is an important factor to be taken into consideration when discussing the feminization of the population affected by the disease.
