Objective: To quantify the consequences of a total ban on indoor tanning for short-term regulatory enforcement, for consumers, and the longer-term health economic effects.
Methods: Instances of illegal solarium prosecutions and tanning bed confiscations in the state of Victoria (population 7 million) were obtained from government surveillance records. Consumer interest for indoor tanning and spray/fake tanning were assessed using Google Trends' Search Volume Index (range 0 to maximum 100). Long-term health economic effects were estimated using a Markov cohort model.
Results: The Victorian Government completed 13 prosecutions and confiscated 39 illegal tanning units. Consumer interest for indoor tanning reduced to less than one quarter of pre-regulation seasonal peaks (Search Volume Index 12/48) while spray tanning interest remained high (70-88). For young Australians over their remaining lives, banning commercial indoor tanning is expected to avert 31,009 melanomas (-3.7%), avert 468,249 keratinocyte cancers (-3.6%) and save over AU$64 (US$47) million in healthcare costs and produce over AU$516 (US$375) million in productivity gains.
Conclusions: Three years after the nationwide ban, regulation enforcement activities have decreased, and consumers have adopted substitute tanning methods.
