Changes in knowledge, attitudes and behaviors of Italian university students regarding contraceptive methods and STDs (1998–2008): a cross-sectional study

Aim The aim of the study is to evaluate changes in opinions and behaviors of university students about sexual attitudes, use and effectiveness of contraceptive methods and sexually transmitted diseases (STDs). Subjects and methods The study was carried out through three surveys in 1998, 2003 and 2008. A self-completion questionnaire, divided into three major sections, was admin- istered. The groups were analyzed with the Chi-square test and the multiple logistic regression analysis; the signifi- cance level was set at p<0.05. Results Contraceptive methods were not used by 12.0, 12.5, and 16.2 % of the sample in 1998, in 2003 and 2008 respectively. The condom was the most common method used by responders, followed by the pill; both methods of birth control are also considered the most effective. In 2008, students demonstrated to have a good knowledge about STDs transmission through sexual intercourse and contra- ceptive use was higher among responders with multiple partners (p00.028), lower in smokers (p00.003) and female gender (p00.001).Conclusion The results highlight the necessity to activate programs on sex education, on the use of contraceptives and STD prevention. Peer education should also be considered.
