Background: In Italy, the circulation of human immunodeficiency virus (HIV) has expanded to include population groups that do not perceive themselves to be "at risk" of HIV infection and who do not even consider undergoing HIV testing. The aim of this study was to describe the socio-demographic and behavioural characteristics, and perceived risk of HIV infection in a sample of blood donors who reported never having been tested for HIV., Materials and Methods: A questionnaire was administered to a sample of donors who called the Italian National AIDS/STI Help Line and reported never having been tested for HIV., Results: The study sample consisted of 164 blood donors: 29.3% had given blood in the preceding 2 years. With regards to at-risk behaviours, 39.6% of the donors interviewed were heterosexuals who had sexual contacts with multiple partners, and 5.5% were men who had sex with multiple male partners. Sexual contacts with female sex workers were reported by 11.6% of first-time donors and 25.7% of repeat donors. Of the 164 donors interviewed, 125 (76.2%) said that the main reason that they had never been tested for HIV was that they did not consider themselves at risk. Among these, 56 (44.8%) reported that they would have sexual contacts with a sex worker, 52 (41.6%) reported that they would have sexual contacts with someone having more than one sexual partner, and 36 (28.8%) reported that they would have sexual contacts without using a condom., Discussion: All the donors interviewed reported that they had never been tested for HIV despite the fact that they had been certainly been tested upon blood donation. These results show that some sexual behaviours may not be perceived as behaviours at risk for acquiring HIV infection. These findings suggest that not all blood donors are knowledgeable about HIV risk behaviours and that an explicit pre-donation questionnaire and effective counselling continue to be important for the selection of candidate donors.

Background: Clients of sex workers represent a relevant target for interventions aimed at the prevention of HIV and sexually transmitted infections (STIs). Within prevention strategies, the AIDS and sexually transmitted infections helpline (Telefono Verde AIDS/ IST, TVA-IST) of National Institute of Health in Italy has provided, since 1987, specific information and counselling interventions., Aim: The present study reports data on anagraphical characteristics and behaviours of clients of sex workers, anonymously reported at TVA-IST in the period 1987-2010., Discussion: Among 95 149 phone calls (14% of the total) considered 99.5% came from males, over 80% aged under 37 years and prevalently from Northern Italy. Among sexual behaviours, unprotected sexual intercourses were reported in the 26% of the calls. Subjects under 27 years reported a higher frequency of unprotected anal intercourse, while they used protection with oral and vaginal intercourses in a greater extent than older ones. Due to differential behaviours within clients of sex workers, specific informative strategies for this targeted population should adequately consider age-related differences.

Background: We conducted an anonymous cross-sectional telephone survey among persons who had never undergone HIV testing to determine their socio-demographic characteristics, behaviour, risk perception and reasons for not being tested., Methods: A questionnaire was administered to adult callers to the Italian National AIDS Help-Line who reported that they had never been tested for HIV., Results: The study sample consisted of 539 individuals. The individual who does not undergo testing is young (median age 30 years), male (85.5%), unmarried (79.0%), employed (70.1%) and with a high educational level (81.6%). More than two-thirds of the respondents had little or no perception of risk. Among persons who had more than one sexual partner, 47.0% do not use a condom. When dividing the respondents into two groups (i.e. high risk and lower risk), the results showed that the proportion of respondents with a high risk was higher among women (73.1%), among persons >35 years (76.3%) and among persons with a low educational level (77.8%). Individuals who had hadbeen seen in health-care facilities also reported high-risk behaviour., Conclusions: The results indicate the socio-demographic characteristics, behaviours, risk perception and reasons for not being tested among a sample of callers to Italy's National AIDS Help-Line, and they confirm the necessity of gearing prevention activities towards heterosexuals and young adults with a low perception of risk.
