[Prevention focused on sexual behavior].

In Italy, studies on the sexual behaviour of young persons are rare, especially those conducted among samples that are representative of the same-age general population. This report presents the preliminary results of a knowledge, attitudes and practices survey on sexual behaviour among a representative sample of individuals 18-26 years of age. The study was begun in 1994, and as of 30 June 1997, 8533 (32%) of the 26,536 questionnaires sent so far have been completed: 3947 (46%) by males and 4586 (54%) by females. 70% of the males and 64% of the females reported that they are sexually active; the median age at first sexual experience is 18 years for both genders. The proportion of respondents who use condoms with occasional sexual partners is low, and only half of the respondents demonstrated an adequate level of knowledge regarding the transmission of HIV.
