Background Tanning beds were classified as first‐group carcinogens in 2009. Nonetheless, research shows that people in industrialized Western countries use tanning beds. Based on the National Cancer Aid Monitoring (NCAM) including representative data on 28,000 individuals from Germany, we quantified the prevalence as a trend from 2015 to 2022, identified determinants of tanning bed use and analysed risk awareness and reasons for use. Methods We used NCAM data from 2015 to 2022 to analyse the trends in the prevalence of tanning bed use (n = 28,000). To determine the characteristics of tanning bed users, risk awareness and reasons, we combined data from the waves 2019 to 2022 (n = 16,000, 49.2% female, 16–65 years) in a pooled dataset to have sufficient power to detect even smaller associations. Results Tanning bed use decreased to 5.1% in 2022. The use of tanning beds in spas, fitness and beauty facilities increased, except during the COVID‐19 pandemic, while the use in tanning salons decreased. Typical tanning bed users were female, middle‐aged, occupied, higher educated, had an immigrant background and were former or current smokers. Risk awareness was the lowest among the current users. The most frequently mentioned reasons were relaxation, enhancement of attractiveness and pre‐tanning. Discussion Our nationwide representative data showed that the prevalence of indoor tanning has decreased. Of concern are the lower risk awareness among current users and the shift in place of use towards facilities associated with health and wellness. To further reduce the use of tanning beds, targeted information, educational campaigns and extended legislation are considered helpful.
