Objectives and methods: As part of the overall evaluation of the Swiss AIDS prevention strategy mostly based on a population approach, annual representative telephone surveys of the general population aged 17-45 (n= 1200 to 2800) have been conducted since 1987 to monitor behavioral change. Validation studies and triangulation methods have been used to cross check the data. Results: A high degree of AIDS knowledge has been rapidly attained. No major changes have been observed in the level of sexual activity (lifetime number of partners, weekly number of sexual intercourse) or in exposure to potential risk of HIV transmission (new steady partner during the year, casual partners in the last 6 months), except among 17-20 age category which has seen a decrease in the proportion of those having had more than 2 partners in their lives. Condom use has increased: with a new steady partner, 40% in 1988 to 64% in 1994 among the 17-30 years old and 57% to 72% among the 31-45; with casual partners: 8% in 1987 to 56% in 1994 among the 17-30 years old and 22% in 1989 to 42% in 1994 among the 31-45. Condom use is more frequent among those having had numerous partners. A comparison with similar studies conducted among adolescents during the 1970s shows that the long-term trend towards greater sexual precocity ceased at the end of the 1980s. Conclusion: These results show that a general population approach to AIDS prevention can achieve large-scale improvements in condom use against HIV infection without inducing other major changes in sexual behavior.
