BackgroundExposure to solar ultraviolet radiation (UVR) and the use of UV-emitting tanning devices are associated with cutaneous malignant melanoma occurrence.ObjectiveThe aim of this study was to quantify the proportion and number of melanoma cases attributable to solar UVR exposure and sunbed use in France in 2015.MethodsPopulation attributable fractions (PAFs) and numbers of melanoma cases attributable to solar UVR exposure were estimated by age and sex using the incidence rates of a 1903 birth cohort as the primary reference. Further analyses were performed using the following: (i) contemporary melanoma incidence rates in low-incidence regions within France and (ii) national melanoma incidence rates for the year 1980, as additional references. Assuming a 15-year lag period, PAF and melanoma cases attributable to sunbed use were calculated using prevalence estimates from a cross-sectional population survey and published relative risk estimates.ResultsIn 2015, an estimated 10 340 melanoma cases diagnosed in French adults were attributable to solar UVR exposure, corresponding to 83% of all melanomas and 3% of all cancer cases in that year. PAFs for melanoma were highest in the youngest age group (30-49 years) and higher in men than in women (89% vs. 79%). A total of 382 melanoma cases occurring in French adults in 2015 were attributed to the use of sunbeds, equivalent to 1.5% and 4.6% of all melanoma cases in men and women, respectively.ConclusionsA considerable proportion of melanoma cases in France in 2015 were attributable to solar UVR exposure, suggesting that targeted prevention strategies need to be implemented.© 2018 European Academy of Dermatology and Venereology.
