Association of sun-seeking behaviors with indoor tanning behavior in US white females during high school/college in Nurses' Health Study II.

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.

Tanning bed use in Germany between 2015 and 2022: Representative data of 28,000 individuals on indoor tanning, risk awareness and reasons for use.

BACKGROUND: Tanning beds were classified as first-group carcinogens in 2009. Nonetheless, research shows that people in industrialized Western countries use tanning beds. Based on the National Cancer Aid Monitoring (NCAM) including representative data on 28,000 individuals from Germany, we quantified the prevalence as a trend from 2015 to 2022, identified determinants of tanning bed use and analysed risk awareness and reasons for use. METHODS: We used NCAM data from 2015 to 2022 to analyse the trends in the prevalence of tanning bed use (n = 28,000). To determine the characteristics of tanning bed users, risk awareness and reasons, we combined data from the waves 2019 to 2022 (n = 16,000, 49.2% female, 16-65 years) in a pooled dataset to have sufficient power to detect even smaller associations. RESULTS: Tanning bed use decreased to 5.1% in 2022. The use of tanning beds in spas, fitness and beauty facilities increased, except during the COVID-19 pandemic, while the use in tanning salons decreased. Typical tanning bed users were female, middle-aged, occupied, higher educated, had an immigrant background and were former or current smokers. Risk awareness was the lowest among the current users. The most frequently mentioned reasons were relaxation, enhancement of attractiveness and pre-tanning. DISCUSSION: Our nationwide representative data showed that the prevalence of indoor tanning has decreased. Of concern are the lower risk awareness among current users and the shift in place of use towards facilities associated with health and wellness. To further reduce the use of tanning beds, targeted information, educational campaigns and extended legislation are considered helpful.

Properties and safety of topical dihydroxyacetone in sunless tanning products: A review.

Sunless tanning products have risen in popularity as the desire for a tanned appearance continues alongside growing concerns about the deleterious effects of ultraviolet radiation exposure from the sun. Dihydroxyacetone (DHA) is a simple carbohydrate found nearly universally in sunless tanning products that serves to impart color to the skin. The Food and Drug Administration (FDA), which regulates sunless tanning products as cosmetics, allows DHA for external use while maintaining that its ingestion, inhalation, or contact with mucosal surfaces should be avoided. Given its widespread use and a paucity of reviews on its safety, we aim to review the literature on the topical properties and safety profile of DHA. Available data indicate that DHA possesses only minimal to no observable photoprotective properties. In vitro studies suggest that, while DHA concentrations much higher than those in sunless tanning products are needed to induce significant cytotoxicity, even low millimolar, nonlethal concentrations can alter the function of keratinocytes, tracheobronchial cells, and other cell types on a cellular and molecular level. Instances of irritant and allergic contact dermatitis triggered by DHA exposures have also been reported. While no other side effects in humans have been observed, additional studies on the safety and toxicity of DHA in humans are warranted, with a focus on concentrations and frequencies of DHA exposure typically encountered by consumers.

Cohort profile: The Swedish Tattoo and Body Modifications Cohort (TABOO).

PURPOSE: The Swedish Tattoo and Body Modifications Cohort (TABOO) cohort was established to provide an infrastructure for epidemiological studies researching the role of tattoos and other body modifications as risk factors for adverse health outcomes. It is the first population-based cohort with detailed exposure assessment of decorative, cosmetic, and medical tattoos, piercing, scarification, henna tattoos, cosmetic laser treatments, hair dyeing, and sun habits. The level of detail in the exposure assessment of tattoos allows for investigation of crude dose-response relationships. PARTICIPANTS: The TABOO cohort includes 13 049 individuals that participated in a questionnaire survey conducted in 2021 (response rate 49%). Outcome data are retrieved from the National Patient Register, the National Prescribed Drug Register and the National Cause of Death Register. Participation in the registers is regulated by Swedish law, which eliminates the risk of loss to follow-up and associated selection bias. FINDINGS TO DATE: The tattoo prevalence in TABOO is 21%. The cohort is currently used to clarify the incidence of acute and long-lasting health complaints after tattooing based on self-reported data. Using register-based outcome data, we are investigating the role of tattoos as a risk factor for immune-mediated disease, including hypersensitisation, foreign body reactions and autoimmune conditions. FUTURE PLANS: The register linkage will be renewed every third year to update the outcome data, and we have ethical approval to reapproach the responders with additional questionnaires.

Public Health Messaging to Address Indoor Tanning: A Scoping Review.

Indoor tanning (IT) is an avoidable skin cancer risk. Although numerous communication interventions have been assessed for IT deterrence, less attention has been paid to the persuasive messages within these interventions. This scoping review summarizes the current peer-reviewed literature on persuasive messages for IT. Overall, 20 articles (21 studies) were included. Most were experimental or quasi-experimental and conducted in the US. Participants were mostly young women who had tanned indoors before. Few studies evaluated persuasive theme; in those that did, health and appearance themes were effective. Narrative and statistical evidence formats were also effective. The included studies also supported normative messages, loss-framed messages, and images. Improved reporting on message design and evaluation would be beneficial for future evidence synthesis. Our understanding of persuasive messages for IT has expanded in recent years, but more research is needed to optimize them.

Bad lighting: Effects of youth indoor tanning prohibitions.

Indoor tanning beds (ITBs) emit UV light at high intensity and have been classified as carcinogenic to humans by the World Health Organization since 2009. We are the first to study the role of state laws prohibiting youths from indoor tanning using a difference-in-differences research design. We find that youth ITB prohibitions reduced population search intensity for tanning-related information. Among white teen girls, ITB prohibitions reduced self-reported indoor tanning and increased sun protective behaviors. We also find that youth ITB prohibitions significantly reduced the size of the indoor tanning market by increasing tanning salon closures and reducing tanning salon sales.

Efficacy of an appearance-based and a health-based sun protection intervention on summer vacationers' behaviours, PRISME cluster randomized crossover trial, France.

OBJECTIVES: Sun-seeking vacationers are particularly vulnerable to melanoma. Appearance-based interventions (ABi) showing skin damage of ultraviolet exposure may be a promising prevention tool to improve skin protection. This study aimed to measure and compare the efficacy of an ABi and a health-based intervention (HBi) on French summer vacationers' behaviours and to identify differences between subpopulations. DESIGN: A cluster randomized crossover trial with three intervention groups (control, ABi, HBi) was conducted in eight campsites on the French Mediterranean coast in summer 2019. METHODS: 1355 vacationers of both sexes and aged 12-55 years were included and followed up after 4 days (T1) and 14 months (T2). Efficacy of interventions was evaluated using multilevel mixed-effect models comparing groups on three outcomes: self-reported sun protection behaviours, sunbathing and skin colour measures. Protection behaviours were analysed according to subpopulations. RESULTS: Compared to controls, the ABi group had a higher protection and sunbathed for fewer hours at T1 and T2. In the HBi group, the skin colour was lighter than controls at T1. When comparing ABi to HBi, ABi participants had lower exposure than HBi at T1 and T2. The protection of people with a 3-years university degree was higher in the HBi group than in others groups while that of people with a secondary school certificate was higher in the ABi group. CONCLUSIONS: Our study provides further evidence of individual sun protection interventions effect in a touristic setting and highlights the relevance of ABi messages to supplement HBi messages, particularly in certain subpopulations with low to intermediate education levels.

The sociological basis of the skin cancer epidemic.

Given the precipitous rise in its incidence in recent decades, skin cancer has been recognized as a growing epidemic. We explore the sociological underpinnings of this epidemic, including: (1) aging of the demographic; (2) human ecologic factors (residing in areas with high ambient ultraviolet levels and a depleted ozone layer); (3) large-scale European migration to more equatorial latitudes; (4) social structures that for centuries minimized miscegenation and maximized segregation; (5) gender-based differences in sunbathing, tanning, sunscreen use, and clothing choice; (6) occupational ultraviolet exposure; (7) the complex interplay of socioeconomic status, race, and urbanization on skin cancer incidence and mortality; (8) the effects of war on skin cancer incidence; (9) cultural shifts in clothing, travel, outdoor sports, recreation, and attitudes towards being tan; and (10) the indirect effects of religion. We show that without these sociological factors, the most common type of cancer would not be nearly as common.

Use of the multi-theory model (MTM) in explaining initiation and sustenance of indoor tanning cessation among college students.

Skin cancer, including melanoma, is the most common cancer worldwide and a significant public health concern. A significant risk factor for melanoma is through increased exposure to ultraviolet (UV) radiation through the use of indoor tanning beds. Although rates of indoor tanning bed use have decreased in recent years, young adults, particularly White, college-age women, comprise the majority of indoor tanning bed users in the United States. The purpose of this cross-sectional study was to explore and explain the initiation and sustenance of indoor tanning cessation among college students using the multi-theory model (MTM) of health behavior change. Data were collected from 254 college students who reported current indoor tanning use using a validated 46-item survey to assess demographics and the MTM constructs. Data were analyzed using multiple linear regression to determine the ability of the MTM constructs to predict the initiation and sustenance of indoor tanning cessation. For initiation of indoor tanning cessation, participatory dialogue: advantages (B = 0.038, p = 0.001), behavioral confidence (B = 0.129, p < 0.001) and changes in the physical environment (B = 0.088, p < 0.001) were significantly associated with indoor tanning cessation following covariate adjustment. For sustenance, only emotional transformation (B = 0.140, p < 0.001) demonstrated a significant relationship with indoor tanning cessation, following adjustment. Findings from this study demonstrate the utility of the MTM in explaining indoor tanning cessation and designing intervention strategies and clinical recommendations to encourage indoor tanning cessation among college students.

Reasons for using indoor tanning devices: A systematic review of qualitative evidence.

PURPOSE: Despite the established causal links to skin cancer, skin ageing and eye inflammation, people continue to use indoor tanning devices (hereafter 'sunbeds'). Understanding the reasons underlying the use of sunbeds is essential for developing effective interventions. The purpose of this study was to collate all existing evidence from qualitative papers published to date that had assessed motivations for using sunbeds. METHODS: Six databases were searched from inception to February 2020 for qualitative studies that explored adults' experiences of using sunbeds. Sixteen studies met the inclusion criteria, and a narrative evidence synthesis was used to collate findings from each primary study. RESULTS: Users of sunbeds were motivated primarily by aesthetic concerns but also by perceived psychological benefits (well-being, confidence and 'fitting in') and physical benefits (improvement in skin conditions such as acne, acquiring vitamin D and preventing sunburn). People also chose indoor tanning over alternatives such as fake tans because they considered the alternatives unacceptable and did not consider indoor tanning a serious health risk. To date, no studies have explored alternatives to meeting non-aesthetic needs related to the use of sunbeds. CONCLUSIONS: This comprehensive explanation for the practice of indoor tanning provides the basis for development of complex interventions to reduce the harm caused by using sunbeds. Effective interventions should include promotion of alternatives, such as different methods of relaxing, to satisfy underlying motivations, changing social norms and correcting misperceptions about health benefits.

Tailored visuals, implementation interventions, and sun safe behavior: A longitudinal message experiment.

OBJECTIVE: One way to communicate skin cancer risk is through ultraviolet (UV) photographs, which can depict the target person (tailored visual) or someone else (stock visual). There is a need for more longitudinal research examining the relative impact of tailored UV photographs compared with other message interventions that could increase sun safe behaviors. METHOD: Students 14-18 years of age (N = 654) at eleven high schools in Utah were recruited to participate in a longitudinal experiment (assessments: pretest, posttest, 1 month follow-up) comparing the relative persuasive impact of receiving either (a) stock and tailored UV photographs or (b) stock UV photographs and an implementation intervention on outdoor tanning behavior. Participants completed measures of fear, appearance norms and benefits, threat susceptibility/severity, self-efficacy, response efficacy, freedom threat, reactance, and outdoor tanning behavior. RESULTS: Compared with the implementation intervention, participants in the tailored UV condition reported increased fear and freedom threat and decreased appearance norms and benefits of tanning immediately following exposure to the intervention and decreased outdoor tanning 1 month after the intervention. Indirect effects also emerged with tailored UV exposure decreasing outdoor tanning via appearance benefits and increasing outdoor tanning when immediate fear triggered psychological reactance. CONCLUSIONS: The results contribute to research on lay reactions to tailored visuals, implementation interventions, and theorizing the indirect effects of affect and cognition across time.
