Aim: This study sought to assess for people living in one large dialysis service in New Zealand their level of sexual functioning and also its importance to them. Background: Although there have been a number of international studies showing significant sexual dysfunction (SD) among people living on dialysis, there have been no published studies in Australia or New Zealand Method: A modified version of the Arizona Sexual Experience (ASEX) questionnaire was used to survey, by post, the dialysis population of the Auckland District Health Board (ADHB) Renal Service. Two new questions, added to the ASEX questionnaire, were asked about their degree of concern over their level of sexual functioning and its impact on their intimate relationships. Responses were analysed as a set of descriptive statistics. Results: This study showed significant levels of SD, 78%, for people living on dialysis in the Renal Service, similar to findings in similar studies elsewhere in the world. Despite these levels of SD, their level of sexual functioning was only of significant concern to 60% of participants and only had a negative impact on their intimate relationship for 42% of participants. Conclusion: The new questions could potentially usefully be used for initial screening to identify whether the person living on dialysis considers they have a problem, in order to determine if a full diagnostic screen for level of sexual functioning was of clinical relevance.
