Association between sunburn and demographic factors and health behaviour among Danish students.

Abstract

Sunburn is associated with an increased risk for skin cancer. Denmark has one of the highest incidences of melanoma in the world, although it is a relatively northern country. The objective of this study was to determine whether sunburn is associated with demographic factors and health behaviour among young Danes. Cross-sectional data of >55,000 15- to 25-year-old students participating in the Danish National Youth Study were collected in 2014. Multilevel logistic regression analysis was used to determine associations. Overall, 45% of the students had experienced at least one sunburn in Denmark, and 60% had experienced one sunburn abroad in the past year. Females had higher odds for sunburns than males. Education and geographical region were associated with sunburn but with opposite trends related for sunburn experienced in Denmark and abroad. Students who had poor dietary habits (only abroad), indulged in binge-drinking, smoked (only in Denmark), and more physical activity (only abroad) had higher odds for having a sunburns. We conclude that sunburn is prevalent among young Danes, especially those travelling abroad. Although we found some associations with demographic factors and health behaviour, there were no evident tendencies, thus indicating that broad population-based campaigning should be the preferred intervention.
