In total, 109 participants completed the survey (20 video contest participants and 89 non–video contest participants), with a survey response rate of 93.2% (109/117). Approximately half of the survey respondents were male. Self-identified race included White (51/109, 46.8%), Hispanic (36/109, 33.0%), Asian or Pacific islander (18/109, 16.5%), Black or African American (16/109, 14.7%), Native American (2/109, 1.8%), and other (8/109, 7.3%). Furthermore, 39.4% (43/109) of respondents reported having 1 sunburn in the past 2 years, and 26.6% (29/109) reported having at least two or more sunburns in the past 2 years. Almost half (52/109) had a history of intentional tanning, 22.9% (25/109) had family members that tan, 45.9% (50/109) had friends who tan, and 26.6% (29/109) had a family history of skin cancer. In the comparison of video contest and non–video contest participants, White students were more likely to participate in the video contest (P<.001), whereas Hispanic and Black students were less likely to participate in the video contest (P<.001 and P=.04, respectively; Table 1).

Although knowledge of skin cancer facts did not differ between video contest and non–video contest participants (P=.14 and P=.11, respectively), video contest participants were more likely to correctly identify 2 tanning myths: “A base tan protects you against getting a sunburn” (P=.02) and “There is no need for sun protection on cloudy or cold days” (P=.04; Table 2). Overall, video contest participants had a higher total knowledge quiz score compared to non–video contest participants (P<.001; Table 3). Furthermore, quiz scores were not significantly different when students who had prior sun safety classroom education, a history of tanning, or gender or family history of skin cancer were compared to those who did not, but higher quiz scores were associated with high sunscreen intentions (P=.01; Tables 3 and 4).

Analysis of all survey respondents revealed that tanning intentions were significantly higher for those with a history of tanning (P<.001), those who have friends that tan (P<.001), and those with family members who tan (P=.001). Future intentions to use sunscreen were higher in video contest participants (P=.01) and White students (P=.002; Table 4). In addition, White students had higher average knowledge quiz scores compared to students who did not self-identify as only White (P<.001; Table 3).

A subsequent analysis of non–video contest participants comparing White students and students of color found no statistical differences in tanning intentions, having family members who tan, having friends who tan, a family history of skin cancer, or a personal history of sunburn. However, students of color had lower tanning myth knowledge scores (P=.01) and reported lower intention to use sunscreen in the future (P=.02; Table 5).

In summary, our study confirms a high percentage of intentional tanning and poor sun-protective behaviors in our adolescent population. In a comparison of those who did and did not participate in a tanning myths–focused video contest, video contest participants had higher sun safety knowledge and higher intentions to use sunscreen, but did not show significant differences in tanning intentions compared to non–video contest participants. In addition, although the video contest was open to all Utah high school students, we had no Black or Hispanic students participate. A subsequent analysis found that students of color had lower sun safety knowledge scores and lower sunscreen use intentions despite having similar sun exposure and tanning histories compared to White students.

We and others have previously shown that sun-protective behaviors decrease as children age [8-10]. Our current study confirms the critical need for continued sun-protective interventions in Utah’s adolescent population: two-thirds had at least one sunburn within the past 2 years and nearly half reported intentional outdoor tanning within the past 2 years. Adolescents who report having family members who purposefully tan have displayed similar behavior [11,12]. Congruently, those who have parental encouragement to practice sun-protective behaviors are significantly more likely to practice them [9,13]. Our study confirms this pattern and another that identifies peer tanning as an important psychosocial factor influencing adolescent tanning behavior [6,14,15]. Interventions focused on parental and peer influence may be beneficial for this population.

Traditional classroom lectures have been shown to be ineffective in promoting photoprotective behavior changes [16-18]. In our cohort, there was no difference in sun safety knowledge or sunscreen and tanning intentions between those that had sun safety education in school versus those that did not. However, our video contest participants were more likely to identify tanning myths resulting in unintentional sun exposure, indicating, “A base tan protects you against getting a sunburn” and “There is no need for sun protection on cloudy or cold days”. Video contest participants also reported increased sunscreen use intentions, although they did not have decreased tanning intentions compared to non–video contest participants. Because preintervention knowledge scores were not assessed, we could not determine whether video contest participants had higher baseline knowledge of tanning myths compared to non–video contest participants. Nevertheless, our findings suggest that although skin cancer prevention may be of importance for video contest participants, as implicated by increased sunscreen use intention, the desire to have tanned skin persists. This is in concordance with recent studies that used individualized appearance-based approaches, such as ultraviolet photography and age-enhancing software to promote photoprotective behaviors [10,19-22]. Thus, future studies evaluating experiential learning methods, such as the video contest described herein, in conjunction with an appearance-based model, may show promise with this population.

Of note, adolescent members of underrepresented racial minority groups did not participate in our video contest. Although skin cancer is indeed far less common in people of color, its incidence is rising, and those diagnosed face a poorer prognosis than do White individuals [23]. Poor prognosis is thought to be caused by delay in treatment, which can result from skin cancer misconceptions and socioeconomic factors influencing access of care in people of color, as well as lack of skin cancer education directed towards this population and their providers [24-27]. These factors may also contribute to the lack of participation in our video contest. In particular, students were asked to use their own recording devices, which may discourage those from resource-limited households. Indeed, adolescents who are people of color in our study had both lower tanning myth knowledge scores and decreased sunscreen use intention. However, our findings did not show differences in tanning history, sunburn history, or family history of skin cancer between White students and students of color. These findings underlie the need for targeted skin cancer prevention education that is community- or family-centered for adolescents who are people of color [28-30].

Our study has several limitations including the small sample size surveyed, which reduces the power of our conclusions and renders them ungeneralizable to the adolescent population as a whole. Furthermore, we cannot comment on the efficacy of the video contest in improving knowledge because preintervention tanning knowledge was not assessed in the video contest participants. The video contest may inherently possess a selection bias for those who have a greater understanding of sun safety or access to video recording devices. Thus, the contest may be unappealing to those who are less informed about sun safety or who are less familiar with video production. Follow-up studies are needed to assess retention of sun-protective knowledge and behaviors long term.

In conclusion, adolescents are at high risk for poor sun-protective behaviors. Participating in a public service announcement video contest may promote sunscreen use, but does not reduce tanning intentions. Our findings highlight the need for targeted photoprotective interventions, specifically for those who report high-risk tanning intentions and also those who are people of color.
