The rise of melanoma in young women, particularly manifesting in trunk skin,1 suggests deliberate UV radiation (UVR) exposure as a plausible cause. Sunless tanning products (STPs), including lotions, spray-on tans, and bronzers, impart a tanned appearance. The role of STPs as substitutes to indoor tanning (IT) remains largely uncharacterized among indoor tanners. The objective of this study was to determine the knowledge and use of STPs among women who tan indoors. To our knowledge, no previous study has described STP use among IT behavioral subtypes.2 Therefore, we also explored whether differences exist between IT subtypes. These findings may inform prevention strategies to reduce IT.
This study was conducted at 2 Midwestern universities. Following institutional review board approval, female students enrolled in fall semester psychology courses were invited to take an online survey assessing IT and STP knowledge and use. Participants were required to have engaged in IT in the past 2 years. Participants were categorized according to how strongly they agreed with statements on IT frequency using descriptions illustrating IT behaviors.2 Resultant subtypes included event tanners, who tanned only occasionally; seasonal tanners, who tanned 1 to 7 times per week seasonally; and regular tanners, who tanned 1 to 7 times per week all year.
Participant characteristics are listed in Table 1. Although over 90% of participants associated IT with skin cancers and photoaging, 85% had engaged in IT in the past year. Generally, increased IT visits correlated with fewer sun-protective behaviors (P = .05).
Eighty-seven percent of participants used STPs, including bronzers (79%), lotions (45%), and spray-on tans (14%). Primary motives for use included appearance enhancement and the belief that STPs were safer than IT, whereas an unnatural orange or streaked look deterred use. Knowledge about IT risks and STP properties differed significantly between users and nonusers (P = .01). Users agreed more strongly that lotions and spray-on tans (P = .03) and bronzers (P < .001) were safer than IT. Moreover, lotion (P = .01) and spray-on tan (P = .03) users reported greater application of daily facial sunscreens than nonusers. Interestingly, lotion users were more likely to report a sunburn tendency (P = .01)
The distribution of IT behavioral subtypes is similar to patterns previously reported.2 Event tanners composed 72% of the sample, and regular tanners were the least represented subtype (6%). Although STP use did not significantly vary between subtypes, regular tanners were more likely to report intent to use spray-on tans (P = .003). Knowledge about IT risks and properties of STPs differed significantly between subtypes (F2,387 = 8.09, P < .001), and regular tanners exhibited less knowledge than event tanners (P < .001) and seasonal tanners (P = .01) (Table 2).
Overall, 87% of study participants used STPs in the past year. This finding is consistent with trends of STP use in the United States.3 Generally, STP users were more knowledgeable than nonusers about the adverse effects of tanning. However, users were more likely to report a sunburn tendency. Users may be unaware of the limited UVR protection STPs afford or may be motivated to use STPs by having a higher photosensitivity skin type. Further exploration of these possibilities is warranted, and both suggest that the addition of UVR protection to STPs may be beneficial.
Use of STPs did not differ significantly between IT subtypes. However, regular tanners demonstrated less knowledge of STP properties and IT effects. An individual's IT subtype is not static; rather, reported IT frequency may be based on recent tanning patterns reflective of one's current psychosocial experiences. We suggest refinement of frequency questions to more accurately depict IT behaviors over the course of a typical year.
Although few participants believed that IT was safe, over 25% reported engaging in IT during the previous month. This incongruity of perceived risk and behavior merits continued investigation of the public's knowledge about IT. Likewise, restricting minors' access to IT is imperative, given that the median age of IT debut was 16 years.
Self-report and limited geographic representation are study limitations. However, since IT prevalence is greatest in the Midwest and among educated women, the college sample is likely representative of typical indoor tanners.4
The desire to appear tan among women is prominent. This study demonstrates that all IT subtypes exhibit high rates of STP use. While continued investigation of the acceptability of alternatives to IT is essential, our findings suggest that encouraging exclusive use of STPs may be a practical prevention strategy. Event tanners, who have the greatest knowledge of IT risks and the most appropriate use of STPs, may be the most amenable to change through education about these appearance-enhancing alternatives. Conversely, since regular tanners' impetus to indoor tan is so salient,2 promoting sole use of STPs may prove ineffective.
