Grandparents fail to communicate sexual matters to the youth. It is their duty to initiate this communication. The escalating numbers of sexually transmitted infections among the youth require grandparents as carers to talk openly. The main purpose of the study was to support grandparents in their communication about sexual matters to the youth. In-depth phenomenological focus group interviews were conducted. Data analysis revealed three themes: grandparents' experience of communication, emotional experience, and the experience of political and social influence. The study developed guidelines for grandparents. The limitations of the study involve the research sample, which was not truly representative of the whole population of East London. The study recommends that all stakeholders be involved in supporting grandparents in their communicating sexual matters to the youth. The researcher recommends further research to describe youth perceptions of communicating sexual matters to grandparents / Health Studies / M.A. (Health Studies)
