Sex Education in Italy: An Overview of 15 Years of Projects in Primary and Secondary Schools.

School-based sex education is essential to improve the knowledge and behavior of young people. Unlike most European countries, sex education in Italy is not compulsory in the school curriculum. Therefore, to assess potential gaps, the main aim of this study was to explore Italian regional initiatives about sex education. A review of gray literature from 2006 to 2021 was conducted in December 2021 on national databases and institutional websites of each Italian region, during which official documents on regional sex education programs were selected. Moreover, a rapid systematic review was carried out in scientific databases to find more information. For both reviews, the sex education topics recommended by UNESCO were used for extracting and analyzing data. A total of 12 Italian regions out of 20 had at least one sex education program, for a total of 39 projects. Overall, all the topics identified by UNESCO have been covered, with considerable differences between northern, central, and southern Italy. Contraception, love, marriage, partnerships, and family were the main topics discussed (hosted in 92% of the regions). Only 25% of the regions discussed pregnancy and birth. Disability was the least debated topic (17%). The rapid systematic review showed that relevant improvements were achieved after sex education interventions. In conclusion, this study underlined important limitations to the implementation of school-based sex education in Italy. Hence, it is necessary to increase sex education interventions to reach adequate standards and flatten the differences not only between Italian regions but also between Italy and other European countries.
