title: Knowledge and behaviour of tourists towards the sun, as studied in a region of northern Greece.
abstract: BACKGROUND
  Melanoma is considered one of the most malignant cancers. Its appearance is related to various factors such as ultraviolet radiation, recurrent sunburn, and phototype. During the summer holidays approximately 14 million tourists from northern European countries visit Greece; this does not include the local tourists.
  
  
  OBJECTIVE
  To discover the extent of European visitors' awareness of the risk of sunburn. To explore the level of knowledge gained by local and foreign tourists from preventive campaigns related to the harmful effects of sun exposure.
  
  
  METHODS
  The sample consisted of 802 travelers from northern European countries, and 726 Greeks who departed from the airport 'Megas Alexandros' during August and September 2002.
  
  
  METHODS
  A structured questionnaire was used to gain data about demographics, family history of skin cancer, and identification of phototype. Also requested was information about the hours of sun exposure, and the use of sunscreen (the pattern of application and its sun protective factor [SPF]). Comparisons of mean values between groups were made by Student's t-test, and the association between categorical variables was tested by Pearson's chi(2). Regression analysis was performed to examine the influence of different factors on the likelihood of being sunburned.
  
  
  RESULTS
  The majority of foreigners belonged to phototype II or III, while the Greek tourists belonged to phototype III. Foreigners had a higher tendency to burn and a lower tendency to tan. Of the total sample, women presented a higher prevalence of sunburn (p <0.05), and they used sunscreen more frequently (p <0.001) than men did (p <0.001), in both groups. The mean SPF used was 17.3 (SD = 8.98) for the foreigners and 16.0 (SD = 2.0) for the Greeks. The media was the main source of information for both groups. Multiple regression analysis showed that skin type was significantly associated with a high probability of sunburn (p <0.001). Moreover, freckles (p <0.05) were a predictive factor for future sunburn.
  
  
  CONCLUSIONS
  Our study showed that skin type is the most important predictor of future sunburn. The role of the primary care physician is to promote and encourage healthy habits, including attitude towards sun exposure. Increased susceptibility to sun-induced damage of persons with phototypes I and II mandates their identification as a target group in all media campaigns.
