Abstract/OtherAbstract:
BACKGROUND: A great number of journeys to sunny destinations are sold to the Danish population every year. We suspect that this travel considerably increases personal annual ultraviolet radiation (UVR) exposure-dose. This is important because such exposure is the main cause of skin cancer, and studies have shown a correlation between intermittent solar UVR exposure and malignant melanoma. OBJECTIVES: To prospectively monitor the behaviour of a group of sun-seekers during a winter sun-holiday and to study behaviours impact on personal UVR exposure-doses. METHODS: In this observation study 25 Danish sun seekers were closely monitored by on-site investigators for 6 days during a winter sun holiday in the Canary Islands, thus avoiding the possible recall bias of retrospective studies with questionnaires. They recorded their location, clothing and sunscreen use in diaries and their personal UVR-doses were measured by personal UVR-dosimeters worn on the wrist. It resulted in 3450 half hour registrations during 150 participation days. RESULTS: On average, each volunteer received a total UVR-dose of 57 standard erythema doses (SED) in 6 days, which is 43% of the annual UVR-dose of a Danish indoor worker. Their exposed body area, sunscreen use and percent of body with sunscreen application were positively correlated to their personal UVR-doses, aswell as there was a strong relationship between location and UVR-doses received. CONCLUSION: The behaviour of the volunteers had a major impact on their personal UVR-doses. Our results emphasize the importance of changing the behaviour among sun seekers with pro-tanning attitudes to reduce their personal annual UVR-exposure-doses and possibly their risk of skin cancer.
