Abstract
OBJECTIVES: to assess the effectiveness of a group and telephone educational intervention with seropositive women about knowledge about HIV sexual transmission prevention. METHODS: a quasi-experimental before-and-after study, carried out with 151 women living with HIV in a Specialized Care Service in a Brazilian capital. The educational intervention was carried out in three moments, with the assessment being carried out before the first and after the last moment. RESULTS: 97.4% of study participants were cisgender women aged between 18 and 58 years; 55.6% considered themselves brown; and 32.5% of interviewees had elementary school. Regarding knowledge about HIV sexual transmission, in 78.5% of items, there was an association (p<0.005) with increased participants' knowledge after receiving the intervention. CONCLUSIONS: the educational intervention helped to increase the knowledge of women living with HIV about the sexual transmission of the infection.
