ObjectivesThis paper examines the awareness and use of nonoccupational HIV post-exposure prophylaxis (nPEP) in Spain, and the factors that influence this awareness.
MethodsBetween June 2009 and July 2010, a mobile unit offered free, rapid HIV tests in a number of Spanish cities. A total of 2545 people were passively recruited and tested, and answered a self-administered questionnaire containing sociodemographic, behavioural and nPEP-related questions. Bivariate and multivariate analyses were performed, stratifying by gender/sexual behaviour.
ResultsSome 34% of the responders were men who have sex with men (MSM), 30% were men who have sex exclusively with women (MSW), and 35% were women. Approximately 26% were foreigners, 46% had a university degree, and 51% had previously taken an HIV test. Overall, 22% were aware of nPEP. Only 2% had ever used it; 70% of these after high-risk sexual intercourse. Awareness was higher among MSM (34%) than women (16%) and MSW (15%). Multivariate analysis showed a lack of nPEP awareness to be associated with being born in Latin America, while awareness increased with the number of previous HIV tests among women and MSW. In MSM, awareness was also associated with having a university degree, the degree of interaction with gay culture, number of partners, and use of the internet as the main way of meeting partners.
ConclusionsnPEP awareness in the studied population was unacceptably low. The promotion of its availability should be made a major objective of prevention programmes, as a complementary measure to condom use.Keywords: education, HIV, preventive measures, prophylaxis, public health policy.

IntroductionNonoccupational HIV post-exposure prophylaxis (nPEP) has been recommended since 1998 [1]. Guidelines for its use exist in almost every country [2][3][4], and in some, including Spain, nPEP is available at no charge in emergency rooms. The cost-effectiveness of nPEP has been demonstrated, especially for high-risk groups [5] there was some initial concern that being aware of nPEP might encourage high-risk behaviour, the evidence shows this fear to have been unfounded [6]. Those who might need nPEP should be made aware of its existence, and request it immediately after high-risk exposure or condom failures (the frequency of which is not negligible) [7]. A number of authors have attempted to characterize the types of person requesting nPEP at health care facilities [8][9][10][11]. Other studies have examined the knowledge that potential users have of its existence. However, most of these studies have focused entirely on men who have sex with men (MSM) [9,[12][13][14][15], while others have concentrated on HIV-positive persons [16]; almost none have dealt with other groups [17], even though nPEP is being indicated mostly in heterosexual exposure to HIV [9,10].The present study assessed the knowledge and use of nPEP among a more heterogeneous population, including HIV-negative men and women of different sexual orientation and with different sexual behaviour...
