ABSTRACT
Indoor tanning using ultraviolet (UV) radiation increases skin cancer risk. However, there is little objective information on when or where indoor tanning is used. We aimed to evaluate tanning salon geography and patterns of use using objective data rather than self-report. We used data from SafeGraph, a company that combines smartphone location data and proprietary geographic data. Our dataset included aggregate, anonymous data from January 1, 2018-December 31, 2020. We developed and validated an algorithm (positive predictive value 92.6%) to identify businesses offering UV indoor tanning. We evaluated tanning salon locations, number of tanning salons per state population, and foot traffic patterns by visits per month, per day of the week, and per hour of the day. Our algorithm identified 7412 businesses as tanning salons. Of those, 2795 (37.7%) had foot traffic data available. The highest concentrations of tanning salons were in Midwestern states. We found peaks in the spring (April) of 2018 and 2019, a slightly later peak (June) in 2020, and a short-term decrease in tanning salon visits during the early phases of the COVID-19 pandemic (March-May 2020). Visits were most frequent during weekdays (Monday-Friday). Peak times of day were 12pm-3pm. Our study has

limitations:

it includes only a small portion of the US population (approximately 10% of mobile devices) and we could not account for indoor tanning outside of tanning salons. Indoor tanning is a known carcinogen, but the majority of information on use is based on cross-sectional surveys. Our study represents new information for public health strategies to decrease exposure to this carcinogen.
