Le data are available on the basic sexual and public health outcomes (as age of sexual debut, number of sexual partners, condom use), to our knowledge, no studies have yet been published on Rwandan young people’s thoughts, perceptions and experiences with sexuality and sexual relationships. Second, the data gathered in the study will be used to inform an intervention to reduce sexual risk in secondary schools.ObjectivesThis study aimed to gain an understanding of young Rwandans’ perceptions on sex and relationships, which is essential for formulating effective SRH promotion interventions. Through analysing the stories they spontaneously recount about sexuality and relationships, we assess their vulnerability for poor SRH and thereby formulate recommendations for interventions that more directly address the needs of young people. We also aim to test the utility of a new qualitative technique: the mailbox technique. We aim to assess if information we get from this 3′-Methylquercetin cancer technique can be used to inform an SRH promotion intervention.Vulnerability: a theoretical frameworkIn analysing and interpreting the results, we use a framework developed by Delor and Hubert (2000) that makes the concepts of `risk’ and `vulnerability’ tangible and operational. We opted for this theoretical framework since the results of our study were to inform an intervention that aimed to reduce sexual risk. We used it as an interpretative framework. Risk in our study is the risk of having poor SRH status (HIV, other sexually transmitted infections (STIs) or an unplanned pregnancy). Vulnerability focuses on why and how some individuals or groups are exposed to higher levels of risk in their lives than others. For example, individuals may have the same chance of getting HIV when having unprotected sex with an HIV-positive partner. However, the chance of having unprotected sex with an HIV-positive partner is higher for some individuals or groups, making them more vulnerable. Delor and Hubert argue that this social aspect of vulnerability can be understood on three levels: first, the social trajectory: each individual goes through different Anisomycin dose phases in her/his life course, which generate different risks; second, the interaction: HIV infection requires two individuals/trajectories to meet. Individuals may adopt different risk-related behaviours according to their position or status in the interaction; and finally, the social context influences the moments, stakes and forms of encounters between different trajectories. Building on Watts and Bohle (1993),Journal of Social Aspects of HIV/AIDSVOL. 11 NO. 1Article OriginalDelor and Hubert formulate a three-by-three matrix, by crossing these three levels with three further ones. Specifically, these are exposure (the risk of being exposed to a certain situation), capacity (possessing the necessary resources to cope with this situation) and potentiality (the risk of being subjected to serious consequences as a result of the situation).In each school, the Rwandan Government installed a mandatory `anti-AIDS club’. This club is tasked with motivating students to take preventive efforts against HIV infection. The students also receive information on biological aspects of SRH in biology classes.ProcedureMethodsStudy settingSix schools were selected with the aim of including a variety of schools encompassing: status (public/private), setting (urban/ rural) and education level (lower/higher-secondary education). All schools included are mixed gen.Le data are available on the basic sexual and public health outcomes (as age of sexual debut, number of sexual partners, condom use), to our knowledge, no studies have yet been published on Rwandan young people’s thoughts, perceptions and experiences with sexuality and sexual relationships.
