As part of a study of risk factors for cervical cancer, the possible change was assessed in the use of condoms after AIDS campaigns. In 1986, samples of 800 women aged 20-39 years were drawn at random from Nuuk/Godthåb (Greenland) and Nykøbing Falster (Denmark). A total of 586 and 661 women were interviewed in Greenland and Denmark, respectively. In 1988, new random samples of 150 women were drawn from the same areas. Totally, 129 Greenlandic and 126 Danish women were included in the study. From 1986 to 1988 the prevalence of ever having used condoms increased significantly among Greenlandic women aged 20-29, whereas no statistically significant changes were observed in Denmark. This pattern was independent of the lifetime number of sexual partners. Neither in Greenland nor in Denmark did the mean lifetime number of sexual partners change from 1986 to 1988.
