How Little Do We Know about HIV and STIs Prevention? Results from a Web-Based Survey among the General Population

Background: Prevention campaigns have led to a significant decrease in new HIV diagnoses in Western Europe, while other sexual transmitted infections (STIs) have shown an opposite trend. Several educational programs are promoted among young students, whereas informational campaigns addressing the general population are scarce. We aimed to investigate the level of awareness regarding STIs among the general population. Methods: We proposed a questionnaire regarding STIs and HIV to the general population in Italy. We assigned 1 point to correct, 0.5 point to partially correct, and 0 point to wrong answers. We collected data about age, sex, region of origin, level of education and whether they were health workers. Results: Overall, 2183 people answered the questionnaire, of which 555 aged over 50 years old. Being male, older than 50 years old, retired or unemployed, not educated, and no regular use of condoms were associated with lower scores. Only 16% of participants knew the Undetectable = Untransmittable (U = U) campaign. Overall, 2131 (97.6%) people think more educational campaigns should be offered. Of interest, 80% said the questionnaire led them to learn more about HIV and STIs. Conclusion: Our study reveals several gaps in general population awareness about HIV and STIs, especially among people aged over 50 years old. Most participants stated that the questionnaire was a learning opportunity. These data suggest that improvement of knowledge could start from easy-to-dispose medium, such as surveys and questionnaires delivered through social media. Furthermore, particular attention should be paid to population segmentation and campaign tailoring to enhance interventions effectiveness. Our data reinforce the need for more informational and educational campaigns tailored to the specific segments of the population
