What do Norwegians know about sexually transmitted diseases?
This paper reports on knowledge about sexually transmitted diseases in Norwegian adults. The sample (572 males and 601 females) was representative of Norwegians aged 15 and above. Data were collected by means of personal interviews and self-completed questionnaires. Out of ten respondents, seven did not know that sexually diseases are not transmitted via toilet seats; six that syphilis is not the most prevalent of the sexually transmitted diseases in Norway; five that both males and females can be infected by chlamydia; four that contraceptive pills do not protect against chlamydia infection; three that condoms protect against all sexually transmitted diseases; and two that condoms protect against gonorrhoea and that females infected by sexually transmitted diseases run higher risk of infertility. Knowledge about sexually transmitted diseases was lowest in the youngest and oldest age groups, and increased monotonously with increased education.
