RESUMEN

BACKGROUND: Ultraviolet (UV) radiation is the most important risk factor for skin cancer development. Sunlight is the main source of UV radiation in the general population. In addition, tanning beds are a source of artificial UV radiation. Since the incidence of skin cancer is increasing worldwide, it is necessary to monitor UV-related risk behaviors such as intentional indoor and outdoor tanning, as well as sun protection behavior in the general population and specific subgroups and settings. This is the aim of the National Cancer Aid Monitoring online (NCAM-online), a continuation and further development of the NCAM. METHODS: The NCAM-online is a longitudinal trend study consisting of four annual survey waves. Each year, 4,000 individuals aged 16-65 years living in Germany will be surveyed using online questionnaires. Each year, intentional indoor and outdoor tanning will be assessed. In addition, varying specific topics regarding skin cancer prevention, such as the utilization of skin cancer screening, will be addressed in the questionnaires. DISCUSSION: The findings of the NCAM-online will provide an important basis for the German Cancer Aid and Working Group on Dermatologic Prevention (Arbeitsgemeinschaft Dermatologische Prävention, ADP) to develop targeted prevention campaigns and projects aimed at preventing skin cancer. The explorative nature of the NCAM-online allows for the identification of new potential starting points for prevention and education. In addition, the longitudinal design allows for a description of the trend in the prevalence of intentional tanning. For tanning bed use, representative trend data from 2012 are available for Germany, to which NCAM-online will add annual data until 2027.

RESUMEN

BACKGROUND: Rates of melanoma have increased dramatically in the United States over the past 25 years, and it has become among the most prevalent cancers for young adult women. Intentional skin tanning leads to a pattern of intense and intermittent UV radiation exposure that is associated with increased risk of melanoma. Frequent tanning is most common among young women and is linked to a variety of sociocultural pressures that negatively impact body image and drive appearance control behaviors. Unfortunately, there are no established interventions designed for frequent tanners. This intervention addresses this gap with unique content informed by body image and acceptance-based interventions. The intervention is delivered using Facebook secret groups, an approach designed to support behavior change and ensure scalability. OBJECTIVE: This study aims to describe the rationale and methodology of a randomized controlled trial of a melanoma prevention program targeting young women engaged in frequent indoor or outdoor UV tanning. METHODS: Participants are women aged 18-25 years who report high-risk tanning (ie, at least 10 indoor tanning sessions in the past 12 months or 10 outdoor sessions in the previous summer). After recruitment and screening, participants completed a baseline survey and were randomly assigned to receive the intervention or an attention-matched control condition. Both conditions were 8-week-long Facebook groups (approximately 25 members each) with daily posting of content. Follow-up surveys are administered at 3, 8, and 18 months after baseline. The primary trial outcome is the combined number of indoor and outdoor tanning sessions reported at the 8-month follow-up. Hypothesized intervention mediators are assessed at the 3-month follow-up. RESULTS: This project was funded by a National Cancer Institute award (R01 CA218068), and the trial procedures were approved by the University of Kentucky Institutional Review Board in February 2020. Trial recruitment and enrollment occurred in 6 waves of data collection, which started in February 2022 and closed in May 2023. The study is closed to enrollment but remains open for follow-ups, and this protocol report was prepared before data analyses. As of February 2024, all participants have completed the 8-month follow-up assessment, and data collection is scheduled to close by the end of 2024 after the collection of the 18-month follow-up. CONCLUSIONS: This trial will contribute unique knowledge to the field of skin cancer prevention, as no fully powered trials have examined the efficacy of an intervention designed for frequent indoor or outdoor tanning. The trial may also contribute evidence of the value in translating principles of body image and acceptance-based interventions into the field of skin cancer prevention and beyond. If successful, the use of the Facebook platform is intended to aid in dissemination as it provides a way to embed the intervention into individuals' everyday routines.

RESUMEN

BACKGROUND: Frequent exposure to ultraviolet light has more detrimental and longer-term effects on the skin in early life than in adulthood. Teenagers with strong sun-seeking behaviors may be more likely to use an indoor tanning bed than those who seek less sun. We aimed to examine associations between sun-seeking behaviors and indoor tanning behavior during high school/college in US females. METHODS: In this cross-sectional study, we used data from The Nurses' Health Study II, a large prospective cohort of US female nurses. We included a total of 81,746 white females who provided responses on the average annual frequency of indoor tanning during high school/college. Our study exposures were number of times/week spent outdoors in a swimsuit and percentage of time wearing sunscreen at the pool/beach as a teenager, weekly hours spent outdoors in direct sunlight during the daytime during high school/college, and number of severe sunburns that blistered between ages 15-20 years. The main outcome was annual frequency of indoor tanning bed usage during high school/college. RESULTS: In multivariable-adjusted logistic regression, we demonstrated positive associations between sun-seeking behaviors and indoor tanning use. Specifically, teenagers who spent 7 times/week outdoors in a swimsuit (adjusted odds ratio [aOR], 95% confidence interval [CI] for daily vs. <1/week: 2.68, 1.76-4.09) were more likely to use indoor tanning beds ≥ 12 times/year. Teenagers with ≥ 10 sunburns (aOR, 95% CI for ≥ 10 vs. never: 2.18, 1.53-3.10) were more likely to use indoor tanning beds ≥ 12 times/year. Also, teenagers/undergraduates who spent ≥ 5 h/week outdoors in direct sunlight (aOR, 95% CI for ≥ 5 h/week vs. <1 h/week: 2.18, 1.39-3.44) were more likely to use indoor tanning ≥ 12 times/year. However, there was not a significant association between average usage of sunscreen at the pool/beach and average usage of indoor tanning beds. Multivariable-adjusted linear regression models also showed similar results. CONCLUSIONS: Teenagers who spent more time outdoors in a swimsuit/direct sunlight or got more sunburns tended to use indoor tanning more frequently. These findings provide evidence that teenagers with stronger sun-seeking behaviors may have more exposure to artificial ultraviolet radiation as well.

RESUMEN

Artificial ultraviolet radiation from tanning beds has been classified as carcinogenic by the International Agency for Research on Cancer in 2009. Several countries have subsequently introduced comprehensive legislation regulating commercial indoor tanning. Specific aspects of these regulations address tanning bed advertising and information requirements for tanning bed customers, which have been previously neglected in international comparisons of indoor tanning regulations. We performed a systematic search regarding legislation on these aspects in 131 legislative units across three continents (North America, Australia/New Zealand, Europe). The legal restrictions found varied widely in type and content. In 49 legislative units we identified total (n = 8) or partial legal bans (n = 41) on advertising for indoor tanning, while 64 legislative units enacted 5regulations that necessitate the dissemination of different types of specific health information to tanning bed customers. Nearly 40% of the legislative units of the study region lacked any legislation on these issues altogether. The heterogenous results emphasize the need for an international dialogue between health authorities and governments to harmonize the regulatory framework for tanning bed advertising and information requirements to a level better protecting the public from skin cancer. Our comprehensive international comparison can serve as a starting point for such a harmonization process that may ultimately protect the public worldwide from misleading tanning bed advertising.

RESUMEN

Tanning beds have been classified as carcinogenic to humans. As a result, many countries have enacted laws regulating the use of commercial tanning beds, including bans for minors. However, there is no international overview of the current legal status of access restrictions for minors that provides details on their specific design regarding age limits and possible exceptions to the statutory regulation. Therefore, we performed a comprehensive web search of current tanning bed legislation for minors on the three continents North America, Australia, and Europe. Our findings regarding the existence and concrete design of access restrictions are presented graphically, using maps. We found a wide variety of different legislations. In Australia, a total ban on tanning beds exists, while in New Zealand, tanning bed use is banned for minors. In Europe, about half of the countries have implemented a strict ban for minors. In North America, we found differences in the age limit for access restrictions between the states, provinces, and territories for those regions that implemented a ban for minors. In the United States, some states have rather "soft bans" that allow use by minors with different types of parental consent. The patchwork in legislation calls for harmonization. Therefore, our comparison is an important starting point for institutions such as the World Health Organization or the European Commission to advance their goals toward a harmonization of tanning bed legislation in general and for minors in particular.

RESUMEN

The objective of this study was to collect prevalence estimates of indoor tanning usage and associated injuries in Canada. The rapid response component of the 2019 Canadian Community Health Survey collected data on the use of tanning equipment in the previous 12 months, including reasons for use, frequency/duration of use, precautions taken and adverse reactions or injuries. The 2019 research findings were as follows, an estimated 3.0% (95% CI: 2.5-3.4%) of Canadians reported that they had used indoor tanning equipment in the past year. Among users, 71.1% (95% CI: 63.9-78.3%) were female and females aged 18-34 were significantly more prevalent users compared to females aged 45 or older. The prevalence of indoor tanning was higher among people without a university degree; however, there were no differences in prevalence by household income or region. Most users indicated they used indoor tanning equipment within a tanning salon (75.3%: 95% CI: 69.1-81.6%) and the most common reason for usage was to develop a "protective" base tan (72.1%: 95% CI: 65.2-78.9%). Over one third (39.2%: 95% CI: 31.1-47.2%) of all users reported 10 or more sessions in the past year. The prevalence of indoor UV tanning usage is declining in Canada. Similar to results in 2014, the majority of users continue to be female, with a large number in the 18 to 34 age group.

RESUMEN

BACKGROUND: Tanning bed use is common among US adolescents, but is associated with increased melanoma risk. The decision to ban tanning bed use by adolescents should be made in consideration of the potential health benefits and costs. METHODS: The US population aged 14 to 17 years was modeled by microsimulation, which compared ban versus no ban strategies. Lifetime quality-adjusted life years (QALYs) and costs were estimated from a health care sector perspective and two societal perspectives: with and without the costs of policy enforcement and the economic losses of the indoor-tanning bed industry. RESULTS: Full adherence to the ban prevented 15,102 melanoma cases and 3299 recurrences among 17.1 million minors, saving $61in formal and informal health care costs per minor and providing an increase of 0.0002 QALYs. Despite the intervention costs of the ban and the economic losses to the indoor-tanning industry, banning was still the dominant strategy, with a savings of $12 per minor and $205.4 million among 17.1 million minors. Findings were robust against varying inspection costs and ban compliance, but were sensitive to lower excess risk of melanoma with early exposure to tanning beds. CONCLUSIONS: A ban on tanning beds for minors potentially lowers costs and increases cost effectiveness. Even after accounting for the costs of implementing a ban, it may be considered cost effective. Even after accounting for the costs of implementing a ban and economic losses in the indoor-tanning industry, a tanning bed ban for US minors may be considered cost effective. A ban has the potential to reduce the number of melanoma cases while decreasing health care costs. LAY SUMMARY: Previous meta-analyses have linked tanning bed use with an increased risk of melanoma, particularly with initial use at a young age. Yet, it remains unclear whether a ban of adolescents would be cost effective. Overall, a ban has the potential to reduce the number of melanoma cases while promoting a decrease in health care costs. Even after accounting for the costs of implementing a ban and the economic losses incurred by the indoor-tanning industry, a ban would be cost effective.

RESUMEN

Introduction: Appalachian communities experience elevated rates of cancer incidence and mortality relative to other regions in the U.S. Specifically, melanoma mortality rates are higher in Appalachia compared to the national average, despite comparable incidence rates. Purpose: To examine differences in self-reported history of skin cancer and prevalence of two UV exposure behaviors between Appalachian and non-Appalachian adults in a nationally representative sample. Methods: Data are from four cross-sectional cycles of the Health Information National Trends Survey (2011-2014) (N=14,451). We examined sunscreen use and tanning bed use, and self-reported history of melanoma and non-melanoma skin cancer. Descriptive and weighted multivariable analyses were conducted to examine sunscreen and tanning bed use, controlling for sociodemographic characteristics. Results: Approximately 8% of the study sample resided in Appalachia (n=1,015). Self-reported melanoma (0.6%) and non-melanoma (3.2%) skin cancer histories were low among Appalachians and did not differ statistically from non-Appalachians (p>0.05). Only 21.2% of Appalachians reported using sunscreen often or always when going outside for more than one hour on a warm, sunny day compared to 27.4% of non-Appalachians (pp=0.04), but there were no regional differences in tanning bed use (OR=1.48, p=0.23) when controlling for sociodemographics and general health status. Implications: Appalachians had comparable histories of self-reported melanoma and non-melanoma skin cancer but were less likely to report sunscreen use than non-Appalachians. Enhanced communication efforts to promote sunscreen use and other UV protection behaviors in Appalachia may be valuable.

RESUMEN

Indoor tanning is an important risk factor for the development of melanoma and non-melanoma skin cancer. With our nationally representative monitoring, we aimed at describing tanning bed use, user characteristics, reasons for use, and risk awareness over time. In the framework of the National Cancer Aid Monitoring (NCAM), we collected representative data on 12,000 individuals aged 14 to 45 years in annual waves of n = 3,000 participants in Germany between 2015 and 2018. We used descriptive statistics and chi²-tests to uncover group differences. To compare data from the different waves, we calculated confidence intervals. The use of tanning beds decreased from 2015 (11.0%, 95%-CI: 9.9%-12.1%) to 2018 (8.8%, 95%-CI: 7.8%-9.8%). However, this decrease did not affect all subgroups. For instance, there was an (non-significant) increase in minors and the prevalence remained stable for individuals with immigrant background and males. Attractiveness was an important reason for tanning bed use in each wave. Over time, there was an increase in medical-related reasons for use. Furthermore, monitoring showed a decrease in risk awareness regarding tanning bed use and ultraviolet (UV) radiation. While it is a positive development that the overall use of tanning beds in Germany has decreased over time, the increasing use by minors despite the legal ban is alarming. Due to the declining risk awareness it is necessary to implement prevention and education campaigns specifically targeted at this group.

RESUMEN

OBJECTIVES: To describe the effect of the first year of a ban on UV tanning device (beds, lamps) use among those under 18 years of age in Ontario, Canada. METHODS: Online questionnaires were completed by adolescents in grades 7 to 12, aged less than 18 years: one when the ban was enacted (May 2014) and a second a year later (May 2015). Questionnaires asked grade, age, sex, and about use of UV tanning devices in the previous year. Recent users were asked about length, frequency, and location of use; service refusals and reasons; awareness of signs/warning labels; and use of eye protection. Weighted estimates and confidence intervals were generated. RESULTS: There were 1561 participants in 2014 and 2305 in 2015. No reduction was observed in UV tanning device use (6.9% vs. 7.9%) in the 12 months preceding the survey. In 2015, most respondents used UV tanning devices in beauty establishments, which was a shift away from gyms and fitness centres as seen in 2014. Non-significant increases occurred in the proportions noticing warning signs/labels (57% vs. 71%), required to wear eye protection (92% vs. 99%), and refused service (17% vs. 21%). Most adolescents who were refused service did not use tanning devices that year (72%). CONCLUSION: Use did not change in the year following enactment of a ban on UV tanning devices among youth in Ontario. The ban did lead to improvements in service refusal, awareness of warning signage, and use of eye protection. As service refusal deterred future use, enhanced enforcement is important.

RESUMEN

BACKGROUND: The major risk factor for skin cancers is exposure to solar and artificial ultraviolet radiation, in particular during childhood and adolescence. In France, a law was restricted for tanning-bed access to adults (≥18 years) since 1997. OBJECTIVE: To evaluate teenagers' artificial tanning behaviour in 2016 and to compare results with those obtained in a similar survey performed in 2011. METHODS: The SOLADO 2011 and 2016 surveys were conducted in a general school in Antony and a technical school in Fontenay-aux-Roses (Paris suburb). RESULTS: In 2016, 630 teenagers (mean age: 14.2 ± 1.9 y: Males/Females: 301/329) completed the questionnaire, 1.3% of teenagers reported using tanning beds, 1.1% tanning pills and 8.9% tanning creams. Between 2011 and 2016, the use of tanning beds decreased from 1.4% to 0.7% in Antony (P = .26) and from 9.5% to 4.8% in Fontenay-aux-Roses (P = .01), and the use of tanning creams from 39.8% to 17.6% in Fontenay-aux-Rose (P = .0007). The incidence of sunburn decreased from 60.5% to 54.0% in Antony (P = .02) and from 55.4% to 42.4% in Fontenay-aux-Roses (P = .05). CONCLUSION: As compared to 2011, teenagers used artificial tanning methods less frequently in 2016. In particular, they used tanning beds less frequently, suggesting that the new stricter legislation has been effective.

RESUMEN

BACKGROUND: The commercial tanning industry has opposed efforts to educate the public on the risks of tanning as well as attempts to restrict minors' access to tanning services. Despite a paucity of supporting literature, statements from the tanning industry claiming that dermatologists routinely use in-office phototherapy for cosmetic treatments and refer patients to tanning salons have successfully derailed and defeated legislation in many states. OBJECTIVE: This study aims to evaluate dermatologist referrals for ultraviolet radiation for cosmetic and medical purposes via tanning beds or phototherapy, as well as their opinions on tanning, legislation, and ultraviolet radiation counseling practices. DESIGN: The study was conducted using a 10-question anonymous survey. SETTING: The participants were surveyed during meetings of three regional dermatologic societies. PARTICIPANTS: One hundred and fifty-two dermatologists attending society meetings participated in the study. MEASURES: The authors measured physician referrals, opinions, and recommendations regarding ultraviolet exposure. RESULTS: Zero physicians (0/152) recommended tanning salons for cosmetic reasons. These 152 dermatologists referred 458 (417 adult, 41 pediatric) out of an estimated 809,369 patients (0.057%) to tanning salons for medical treatment. Of these physicians, 76 out of 152 and 15 out of 152 reported referring at least one adult or one pediatric patient, respectively, within the last year. All respondents supported ultraviolet tanning legislation and discouraged cosmetic tanning. CONCLUSION: These findings directly contradict the assertion that dermatologists use ultraviolet radiation for cosmetic purposes or routinely refer patients to tanning salons. This study underscores the complex nature of ultraviolet radiation, as dermatologists infrequently utilize ultraviolet radiation for medical purposes and unanimously support restrictive legislation. In addition, these dermatologists counsel against cosmetic tanning and list tanning bed use among their highest concerns with regard to the health of pediatric patients.

RESUMEN

BACKGROUND: There is increasing interest in using social media sites such as Facebook to deliver health interventions so as to expose people to content while they are engaging in their usual social media habit. This formative intervention development study is novel in describing a preliminary test of using the secret group feature of Facebook to deliver a behavioral intervention targeting users of indoor tanning beds to reduce their risk of skin cancer. Intervention content was designed to challenge body image-related constructs associated with indoor tanning through the use of dissonance-inducing content. OBJECTIVE: To evaluate engagement with and acceptability of using a secret Facebook group to deliver a healthy body image intervention to young women engaged in indoor tanning. METHODS: Seventeen young women completed a baseline survey and joined a secret Facebook group with intervention content delivered via daily posts for 4 weeks. Engagement data was extracted and acceptability was measured via a follow-up survey. RESULTS: The study had a high retention rate (94%, [16/17]). On average, posts were viewed by 91% of participants, liked by 35%, and commented on by 26%. The average comment rate was highest (65%) for posts that elicited comments by directly posing questions or discussion topics to the group. Average intervention acceptability ratings were highly positive and participants reported feeling connected to the group and its topic. Average rates of past 1-month indoor tanning reported following the intervention were lower than the baseline rate (P=.08, Cohen d=0.47). CONCLUSIONS: This study is novel in demonstrating participant engagement with and acceptability of using Facebook secret groups to deliver a dissonance-inducing intervention approach that utilizes group-based discussions related to body image. The study is also unique within the field of skin cancer prevention by demonstrating the potential value of delivering an indoor tanning intervention within an interactive social media format. The findings suggest that Facebook metrics of intervention post engagement (ie, likes and comments) may vary based on post types and that designing specifically labeled discussion posts may be helpful for soliciting engagement as well as challenging beliefs.

RESUMEN

BACKGORUND AND OBJECTIVES: Melanoma is steadily increasing over the past decade. Recent studies confirmed a link between tanning bed use and melanoma. We sought to determine the prevalence and frequency of tanning bed among young patients with melanoma. METHODS: We retrospectively analyzed tanning bed use among young melanoma patients compared to controls selected from the hospital medical records. A telephone survey investigated family history of melanoma or skin cancer, hair color, eye color, skin type, tanning bed use, and patient awareness of dangers of tanning bed use. RESULTS: A total of 601 melanoma cases were identified; 265 (44%) completed the telephone survey as did 195 (31%) controls. Of these 460 subjects, 260 were female. Females were 3.0 times more likely to have used a tanning bed. Melanoma patients had natural light color hair, blue-green eyes, and 2.0 times more likely to use a tanning bed than controls. Among the tanning bed users, 90% were aware of danger of tanning bed. CONCLUSIONS: Our study found that tanning beds were more likely to be used by young women, the majority of whom are aware of the associated risks. Eliminating the use of tanning beds should be considered to decrease the incidence of melanoma.

RESUMEN

OBJECTIVE: To explore tanning behaviors and whether a discrepancy between current and ideal skin tones exists. PARTICIPANTS: The sample included 78 Caucasian women from a mid-sized midwestern university. METHODS: Data were collected in spring 2012 via a paper questionnaire. RESULTS: Sixty-two percent of the sample regularly engaged in salon tanning at least once per week, with an average frequency of 2.5 visits per week. Thirteen percent endorsed regularly tanning 4 or more times per week, and 26% reported visiting a tanning bed more than once in a 24-hour period. Ninety-four percent wished their current skin tone was darker, and ideal tone was significantly darker than current tone. CONCLUSIONS: The data suggest that the young Caucasian women in this sample tend to be dissatisfied with their current skin tone to an extent that leads the majority of them to engage in risky, potentially cancer-causing behavior by either salon tanning or considering tanning in the future as time and finances become available.

RESUMEN

Malignant melanoma (MM) and non-melanoma skin cancer (NMSC) are increasingly common and both can be fatal. In 2009 the World Health Organization (WHO) classified the whole ultraviolet spectrum and tanning beds as carcinogenic to humans, placing them in the same category as asbestos and tobacco. Despite this, the trend for indoor tanning continues. A growing body of evidence has now associated indoor tanning with an increased risk of MM and NMSC. As a result, there has been an upsurge in regulations in the tanning industry ranging from age restrictions to complete bans on commercial tanning. This article examines the evidence and strengthens the case for a complete ban of a recognised modifiable risk factor for cutaneous malignancy.

RESUMEN

During the course of a day human skin is exposed to solar UV radiation that fluctuates in fluence rate within the UVA (290-315 nm) and UVB (315-400 nm) spectrum. Variables affecting the fluence rate reaching skin cells include differences in UVA and UVB penetrating ability, presence or absence of sunscreens, atmospheric conditions, and season and geographical location where the exposure occurs. Our study determined the effect of UVA fluence rate in solar-simulated (SSR) and tanning-bed radiation (TBR) on four indicators of oxidative stress---protein oxidation, glutathione, heme oxygenase-1, and reactive oxygen species--in human dermal fibroblasts after receiving equivalent UVA and UVB doses. Our results show that the higher UVA fluence rate in TBR increases the level of all four indicators of oxidative stress. In sequential exposures when cells are exposed first to SSR, the lower UVA fluence rate in SSR induces a protective response that protects against oxidative stress following a second exposure to a higher UVA fluence rate. Our studies underscore the important role of UVA fluence rate in determining how human skin cells respond to a given dose of radiation containing both UVA and UVB radiation.
