Toosi B, Kalia S. Seasonal and Geographic Patterns in Tanning Using Real-Time Data From Google Trends. JAMA Dermatol. 2016;152(2):215–217. doi:10.1001/jamadermatol.2015.3008
The incidence of skin cancer is increasing, partly due to the usage of tanning beds.1-3 Few studies have considered the temporal pattern of tanning, with most of the previous studies using cross-sectional data from surveys that are prone to bias of memory recall by individual participants. Herein, we demonstrate a novel methodology and use Internet search data to elucidate seasonality and peak interest times in tanning practices.
The data in this study were collected from Google Trends.4 For a given search term, Google Trends computes how many searches have been done relative to the total number of searches done on Google.
