22 2019 Skin Cancer Prevention Progress Report BEHAVIORAL SURVEILLANCE INDICATORS Increasing the use of sun protection and decreasing the prevalence of sunburn and indoor tanning are critical to preventing future cases of skin cancer.These behavioral surveillance indicators can provide timely information about our progress in reducing exposure to harmful UV radiation. The latest data on use of sun protection (shade, clothing, wide-brimmed hats, and sunscreen), indoor tanning, and sunburn among U.S. adults are available from the Cancer Control Supplement of the 2015 National Health Interview Survey (NHIS).The most recent data on sunscreen use, indoor tanning, and sunburn among U.S. high school students are available from the 2013, 2015, and 2017 national Youth Risk Behavior Survey (YRBS). Sun Protection According to the 2013 YRBS (the latest year for which these data are available), 10.1% of high school students use sunscreen with an SPF of 15 or higher when outside for more than 1 hour on a sunny day. 19 Sunscreen use was higher among girls (13.2%) than boys (6.9%).The prevalence of sunscreen use among high school students did not change significantly from 2005 to 2013. Although use of sun protection appears to be increasing slightly among adults (Figure 3), there is still room for improvement. Sun protection strategies differ by sex, and more than one-quarter of women and one-third of men do not consistently use any form of sun protection (Figure 4).
