AIDS in The Netherlands: the effects of several years of campaigning.

One of the primary aims of acquired immunodeficiency syndrome (AIDS) prevention campaigns in the Netherlands has been to inform the public of the facts about AIDS, thereby stimulating informed, but voluntary action to prevent transmission of the human immunodeficiency virus (HIV). By conducting successive population surveys from April 1987 until October 1989, the effects of this approach were assessed. Twice a year, approximately 1000 respondents, a random sample from the general population, were interviewed about AIDS and safe sex. Additionally, condom sales figures and STD incidences were evaluated. It appears that knowledge about the prevention of HIV transmission with condoms has reached 98% of the sample. During the study, there was an increase in the number of people who expressed an intention to use condoms or who already used them. Behaviour, however, appeared to fall short of intention. The observations were confirmed by condom sales figures and STD incidences. We conclude that the AIDS policy in the Netherlands has had beneficial effects, reflected by several indices.
