Beachgoers in Denmark increasingly used sunscreen, higher Sun Protection Factor (SPF) products, and applied more lotion between the 1990s and 2016. This trend indicates improved sun safety practices over two decades.
Area of Science:
- Dermatology
- Public Health
- Environmental Health
Background:
- Sun exposure poses risks, including skin cancer.
- Sunscreen use is a key protective measure.
- Trends in sunscreen application practices are important for public health initiatives.
Purpose of the Study:
- To analyze trends in sunscreen usage frequency, Sun Protection Factor (SPF), and application quantity among Danish beachgoers.
- To assess changes in sun protection behaviors from the 1990s to 2016.
Main Methods:
- Observational study design.
- Surveys of 1,306 beachgoers regarding sunscreen use and SPF.
- Measurement of sunscreen quantity applied by 143 beachgoers via bottle weighing.
Main Results:
- Female sunscreen use rose from 45% (1997) to 78% (2016); male use increased from 39% to 49%.
- Median SPF increased significantly, averaging one unit yearly, from SPF 5 to SPF 20.
- Applied sunscreen quantity increased from 0.48 mg/cm² (1992) to 0.57 mg/cm² (2016).
Conclusions:
- Danish beachgoers demonstrated a significant positive trend in adopting sun protection measures.
- Increased frequency of use, higher SPF, and greater application amounts suggest enhanced awareness and practice of sun safety.
