The knowledge and attitudes of a female at-risk population towards the prevention of AIDS and sexually transmitted infections in Tehran

BACKGROUND The female at-risk population represents a subgroup that is both a crucial determining factor in acquired immune deficiency syndrome (AIDS) transmission and a gap in the existing literature in Iran. The objective of this study was to evaluate the level of sex workers' knowledge towards to safe procedures of sexually transmitted infection and AIDS prevention as well as attitudes towards AIDS. METHODS A sample of 256 female sex workers working in Tehran was obtained by a variety of methods. Appropriate questions for the assessment of knowledge and attitude were developed based on previous studies. RESULTS The mean age of the subjects was 26.8 ± 6.1 years (ranging from 16 to 45). Methods of transmission were widely recognized, despite the exception that few realized oral (23.4%) and anal (44.9%) intercourse as methods of human immunodeficiency virus (HIV) transmission. Most subjects knew that AIDS currently has no cure (81.2%) and no vaccine (73.4%). Most also acknowledged that HIV is transmissible from people who do not know they are HIV positive (59.4%), proper condom use can reduce the possibility of infection (78.1%), and so can having a single sexual partner (68.8%). Of the participants, 43.4% knew that an HIV-positive person can seem perfectly healthy. CONCLUSIONS Knowledge towards sexually transmitted infections (STIs) and condom use is still inadequate, especially regarding risky behaviors such as anal sex, and attitudes are mainly negative. Identifying at-risk populations, HIV-positive sex workers, education and campaigns to change the attitudes towards AIDS should be regarded a high priority in Iran.
