Attitudes of Serodiscordant Couples Towards Antiretroviral-Based HIV Prevention Strategies in Kenya: A Qualitative Study

This qualitative study aims to gain in-depth information about the attitudes of HIV-serodiscordant couples towards two new methods of HIV prevention; Pre-Exposure Prophylaxis and Treatment as Prevention, both of which have been recently recommended by the World Health Organisation. Semi-structured interviews were conducted with 38 individuals in a serodiscordant relationship in Western Kenya. Topic guides were used to elicit information on perceived benefits, concerns, and preferences towards Treatment as Prevention and Pre-Exposure Prophylaxis. Data evaluation and thematic generation were developed using framework analysis. Results suggest that the majority of participants, irrespective of gender and HIV status, found Treatment as Prevention the more acceptable strategy. Key factors influencing this decision were HIV-negative participants' limited motivation to take prophylactic antiretrovirals and the likely health improvements Treatment as Prevention offers HIV-positive partners. However, issues were raised concerning the likelihood of low concurrent condom use and poor medication adherence when using these preventative approaches. It was concluded that the adoption of Treatment as Prevention as a method of HIV control in Kenya is likely to be more readily accepted by serodiscordant couples than Pre-exposure Prophylaxis. However, future implementation of either strategy would require measures to address the possibility of risk compensation and poor adherence.
