BackgroundThe incidence of malignant melanoma is increasing faster than any other cancer, and it is now the second most common cancer in young adults. Most skin cancer prevention campaigns are based on the hypothesis that improved skin cancer knowledge leads to a change in sun-related behaviour.AimThe aim of this study was to analyse the relationship of good skin cancer knowledge in a high knowledge group-medical students-with sun-related behaviours and tanning attitudes in Ireland.MethodsA cross-sectional survey was conducted on university students studying medicine in a single institution.ResultsThe final analyses included 312 complete questionnaires. Two hundred three (65.27%) were female, and 108 (34.73%) were male. The majority (65.06%) were aged 21-25 years. The mean skin cancer knowledge score was 89.77%. There was a positive attitude to tanning with 201 (64.63%) participants feeling more attractive with a suntan and 174 (55.94%) feeling better about themselves with a suntan. More than half of participants, 196 (54.17%), got a suntan last year, 171 (54.81%) participants sunbathed, 188 (60.26%) got sunburned and 30 (9.61%) reported using sunbeds previously. Those with a positive attitude to tanning were more likely to sunbath, suntan and get sunburned. High skin cancer knowledge scores were positively associated with high-risk sun behaviours (Spearman's rank correlation coefficient = 0.156, P = 0.006).ConclusionUrgent action is needed to promote skin cancer prevention. This study adds to the evidence that melanoma prevention strategies should preferentially target tanning attitudes rather than skin cancer knowledge.
