Background Australia and New Zealand have the highest skin cancer incidence rates worldwide, and sun exposure is the main risk factor for developing skin cancer. Sun exposure during childhood and adolescence is a critical factor in developing skin cancer later in life. Objective This study aims to test the effectiveness of wearable UV sensors to increase sun protection habits (SPH) and prevent sunburn in adolescents. Methods During the weeklong school leavers outdoor festival (November 2019) at the Gold Coast, Australia, registered attendees aged 15-19 years were recruited into the field study. Participants were provided with a wearable UV sensor and free sunscreen. The primary outcome was sun exposure practices using the SPH index. Secondary outcomes were self-reported sunburns, sunscreen use, and satisfaction with the wearable UV sensor. Results A total of 663 participants were enrolled in the study, and complete data were available for 188 participants (188/663, 28.4% response rate). Participants provided with a wearable UV sensor significantly improved their use of sunglasses (P=.004) and sunscreen use both on the face (P<.001) and on other parts of the body (P=.005). However, the use of long-sleeve shirts (P<.001) and the use of a hat (P<.001) decreased. During the study period, 31.4% (59/188) of the participants reported receiving one or more sunburns. Satisfaction with the wearable UV sensor was high, with 73.4% (138/188) of participants reporting the UV sensor was helpful to remind them to use sun protection. Conclusions Devices that target health behaviors when outdoors, such as wearable UV sensors, may improve use of sunscreen and sunglasses in adolescents.

Objective To review the role of sunlight in skin aging and skin cancer formation, and to provide guidelines on the use of sunscreens to minimize the adverse effects of sun damage. Data Sources A MEDLINE search of applicable articles on ultraviolet (UV) radiation, melanoma, sunscreens, and skin cancer, evaluating both human and animal studies. Published and unpublished original research as well as clinical experience were also used. Data Synthesis The interaction of UV radiation and skin type plays a central role in melanoma formation. Mortality from melanoma is highest in geographic locations near the equator, where UV intensity is greatest. The incidence of melanomas in light-complected individuals (skin types I-III) is several times higher than those with darker skin types (types IV-VI), even in similar geographic regions. The UVB portion of the spectrum appears to be primarily responsible for skin cancer formation and photoaging, while short wave UVA rays play a significant contributing role. Regular sunscreen use has been shown to reduce the formation of precancerous actinic keratoses (AK) lesions by 36%. A dose-response relationship has also been found between the amount of sunscreen used and AK formation. Conclusions Sunscreens have now been shown to reduce the carcinogenic effects of sunlight in humans. Patients should be advised of the long-term consequences of sun exposure and the benefits of regular sunscreen use.

BACKGROUND Adolescents are susceptible to excessive ultraviolet exposure due to intentional tanning, outdoor lifestyles and poor sunscreen adherence. As skin cancer incidence continues to rise in the United States, effective and focused interventions are needed to encourage photoprotective behaviors. OBJECTIVE This study seeks to determine poor photoprotective behavior risk factors in adolescents residing in Utah and whether video contest participants have increased sun protective knowledge and intentions. METHODS In this cross-sectional study, we surveyed Utah high school students (n=20) who participated in a tanning myths-themed public service announcement video contest. A control cohort of students who did not participate in the video contest were also surveyed (n=89). Demographics, sun exposure history, intentions to tan, and intentions to use sunscreen were documented. Knowledge of tanning myths was assessed with a seven-question sun safety quiz. RESULTS Survey response rate was 93%. 66.1% reported at least one sunburn and 47.7% reported intentional tanning within the past two years. Higher tanning intentions were associated with personal (p<0.001), family (p=0.001), and peer (p<0.001) history of tanning. Video contest participants had higher sun safety quiz scores (p<0.001) and higher sunscreen use intentions (p=0.011), but did not have decreased tanning intentions (p=0.47) compared to non-video contest participants. Hispanic and African-American students were less likely to participate in the video contest (p<0.001 and p=0.04, respectively). Comparing white and non-white students, there were no differences in sun exposure history, but non-white students had lower sun safety knowledge (p=0.01) and lower sunscreen use intention (p=0.02). CONCLUSIONS Sun safety educational disparities exist, and targeted efforts are needed to encourage photoprotective behaviors in high risk populations. Our findings suggest that video contest participation may encourage sunscreen use and sun protection awareness.

Vitamin D Levels

Introduction: Vitamin D deficiency is very prevalent in world population and growing evidence shows that also athletes are affected. Vitamin D deficiency causes beside bone disorders, musculoskeletal pain, muscle weakness and is associated with many other health disorders. For athletes in particular it may impair training and performance, prolong recovery and increase risk of injury. We therefore analyzed vitamin D levels in Swiss athletes focusing on prevalence according to age, gender, seasonal variations, indoor or outdoor sports, sunscreen use and vitamin D supplementation. Methods: This study was performed in a convenient sample of 655 Swiss Olympic athletes over one year. Blood samples were obtained and a questionnaire was filled in at Swiss Olympic Medical Centers or Bases during an annual routine exam. Data were then sent to the central laboratory of the Aarau hospital where they were processed and sent to us in an anonymized version. Vitamin D levels were categorized into deficiency (≤ 50 nmol/l), insufficiency (between 50 and 75 nmol/l) and adequate levels (> 75 nmol/l) of 25-hydroxyvitamin D. By means of the questionnaire, we assessed age, gender, type of sport, symptoms possibly related to vitamin D deficiency during the last year, frequency of sunscreen use and vitamin D-containing medications of the athletes. Results: 13.5% of the participants (total number = 651) presented a vitamin D deficiency, 37.8% a vitamin D insufficiency so that more than half of the athletes (51.2%) had inadequate vitamin D levels. Inadequate vitamin D levels were more prevalent in younger athletes, during seasons with lower sun exposure, in indoor sports during the sun deprived seasons, in athletes without vitamines supplementation and in athletes of lower Swiss Olympic classes compared to their counterparts. Conclusions: The results of the study show that the prevalence of inadequate vitamin D levels in Swiss athletes is substantial for younger athletes (< 18 years of age) and for indoor athletes during sun deprived periods of the year. However, a general vitamin supplementation containing vitamin D reduced the prevalence of vitamin D inadequacy which is especially relevant during sun deprived seasons.

1549 Background: With the dramatic increase in ultraviolet-induced skin damage, including melanomas and skin carcinomas, advocating the benefits of reasonable and moderate exposure to sunlight is a public health priority in most Western countries. Objective: The aim of this study was to investigate the nature and quality of the information posted on the Internet about the effects of the sun on health and about sun protection. Methods: We used eight terms with eight search engines to identify relevant websites providing sun protection advice on the French-speaking web. This information was compared to the recommendations issued by nine official organizations. Influence of website quality and commercial links on the quality of the advice provided was evaluated. For the purposes of this comparison, we attributed marks to the following four criteria: 1) risks and benefits of sun exposure; 2) sun avoidance; 3) clothing recommendations; and 4) sunscreen use. Results: The search identified 1,551 links. After exclusion of sites duplicated either within or between search engines, and of websites used as references, we found 129 web pages dedicated to sun protection advice. Data on the effects of the sun and sun protection were deficient in most websites in comparison to official organization websites. It was even better than the web pages or websites respecting quality criteria. Commercial links tended to score poor marks for 1, 2, and 3 but better marks for 4 (sunscreen use). Conclusions: We showed the limits of web-based resources on the French-speaking web regarding sun protection advice. Poor quality of most of the websites and commercial conflict of interest with sunscreen manufacturers may explain these limits. No significant financial relationships to disclose.
