RESUMO

BACKGROUND: Indoor tanning (IT) in fitness facilities encourages a misleading positive relationship between tanning and health. While IT in Canadian fitness facilities has been studied, American literature regarding this topic is lacking. OBJECTIVES: The objective of this study is to evaluate availability, cost, reported risks, and adherence to legislation of IT in American fitness clubs. METHODS: This was a cross-sectional study utilizing a telephone questionnaire to survey gyms across all 50 states. The key term "fitness club" was searched in the Yellow Pages and 20 facilities from each state were randomly included into the study. Data were described descriptively and Pearson χ2 tests were used to compare IT prevalence and rates of noncompliance between population groups. Regression analysis examined potential relationship between cost and prevalence of IT. RESULTS: Of the 1000 fitness clubs surveyed, 44.4% (444/1000) offered IT. The overall noncompliance rates for age, rest time, and eye protection were 13.8% (54/390), 26.0% (20/77), and 27.8% (85/225), respectively. The most common risk reported was skin cancer (61.6%), but many facilities were unsure of risks (27.0%) and some described no risk associated with IT (3.2%). The average cost for monthly unlimited tanning was 33 ± 13.96 USD. A state-to-state comparison showed a statistically significant inverse relationship between mean cost and prevalence of IT (P = .013, [r]= -0.35). CONCLUSION: The prevalence and noncompliance rates of IT in fitness clubs contradict the healthy lifestyles they are working to promote. To limit harms, legislations should be standardized and more strictly enforced. Additionally, public education on IT risks and the use of higher costs may help minimize IT use.

RESUMO

Importance: UV radiation emissions from indoor tanning devices are carcinogenic. Regulatory actions may be associated with reduced exposure of UV radiation at a population level. Objective: To estimate the long-term health and economic consequences of banning indoor tanning devices or prohibiting their use by minors only in North America and Europe compared with ongoing current levels of use. Design, Setting, and Participants: This economic analysis modeled data for individuals 12 to 35 years old in North America and Europe, who commonly engage in indoor tanning. A Markov cohort model was used with outcomes projected during the cohort's remaining life-years. Models were populated by extracting data from high-quality systematic reviews and meta-analyses, epidemiologic reports, and cancer registrations. Main Outcomes and Measures: Main outcomes were numbers of melanomas and deaths from melanoma, numbers of keratinocyte carcinomas, life-years, and health care and productivity costs. Extensive sensitivity analyses were performed to assess the stability of results. Results: In an estimated population of 110 932 523 in the United States and Canada and 141 970 492 in Europe, for the next generation of youths and young adults during their remaining lifespans, regulatory actions that ban indoor tanning devices could be expected to gain 423 000 life-years, avert 240 000 melanomas (-8.2%), and avert 7.3 million keratinocyte carcinomas (-7.8%) in North America and gain 460 000 life-years, avert 204 000 melanomas (-4.9%), and avert 2.4 million keratinocyte carcinomas (-4.4%) in Europe compared with ongoing current levels of use. Economic cost savings of US $31.1 billion in North America and €21.1 billion (US $15.9 billion) in Europe could occur. Skin cancers averted and cost savings after prohibiting indoor tanning by minors may be associated with one-third of the corresponding benefits of a total ban. Conclusions and Relevance: Banning indoor tanning may be associated with reduced skin cancer burden and health care costs. Corresponding gains from prohibiting indoor tanning by minors only may be smaller.

RESUMO

OBJECTIVE: To assess whether an association exists between financial links to the indoor tanning industry and conclusions of indoor tanning literature. DESIGN: Systematic review. DATA SOURCES: PubMed, Embase, and Web of Science, up to 15 February 2019. STUDY SELECTION CRITERIA: Articles discussing indoor tanning and health were eligible for inclusion, with no article type restrictions (original research, systematic reviews, review articles, case reports, editorials, commentaries, and letters were all eligible). Basic science studies, articles describing only indoor tanning prevalence, non-English articles, and articles without full text available were excluded. RESULTS: 691 articles were included in analysis, including empiric articles (eg, original articles or systematic reviews) (357/691; 51.7%) and non-empiric articles letters (eg, commentaries, letters, or editorials) (334/691; 48.3%). Overall, 7.2% (50/691) of articles had financial links to the indoor tanning industry; 10.7% (74/691) articles favored indoor tanning, 3.9% (27/691) were neutral, and 85.4% (590/691) were critical of indoor tanning. Among the articles without industry funding, 4.4% (27/620) favored indoor tanning, 3.5% (22/620) were neutral, and 92.1% (571/620) were critical of indoor tanning. Among the articles with financial links to the indoor tanning industry, 78% (39/50) favored indoor tanning, 10% (5/50) were neutral, and 12% (6/50) were critical of indoor tanning. Support from the indoor tanning industry was significantly associated with favoring indoor tanning (risk ratio 14.3, 95% confidence interval 10.0 to 20.4). CONCLUSIONS: Although most articles in the indoor tanning literature are independent of industry funding, articles with financial links to the indoor tanning industry are more likely to favor indoor tanning. Public health practitioners and researchers need to be aware of and account for industry funding when interpreting the evidence related to indoor tanning. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42019123617.

RESUMO

Few studies have investigated pricing and promotional practices used by the indoor tanning industry, despite their potential to promote indoor UV tanning-a well-established risk factor for melanoma skin cancer. Posing as potential customers, we telephoned 94 indoor tanning businesses in six United States (U.S.) cities and requested pricing information. The price of a single tanning session ranged from $0 to $23, and was lower at facilities that offered indoor tanning as a secondary service (mean $4.82 and free in 35%) than at tanning salons (mean $16.45). Session prices in salons could be as low as $1.50 with daily use of an unlimited monthly plan. Free indoor tanning, monthly packages, and memberships encourage increased use. Policies that limit free indoor tanning or that restrict pricing and advertising for indoor tanning exist in several places in the U.S. and Europe. Future research should evaluate whether those policies are effective in reducing indoor tanning.

RESUMO

BACKGROUND: Melanoma is a life-threatening disease of the skin with an increasing incidence of approximately 87 000 new cases treated per year in the European Union and the European Free Trade Association states resulting in considerable costs for the society. Since the use of sunbeds is known to be a risk factor, which can be easily avoided, costs of malignant melanoma attributable to sunbed use are modelled in the present study. METHODS: Costs-of-illness of melanoma were calculated and compared for all member states of the European Union and the European Free Trade Association states using an established modelling approach. Calculations were based on a systematic literature research. For countries with no available information on cost-of-illness the gross domestic product, health expenditures and gross national income served as a basis for extrapolation of costs. International comparison was enabled by adjusting costs by the national purchasing power parity. RESULTS: After adjusting melanoma treatment costs for the purchasing power parity, direct costs per patient vary between € 1056 in Romania and € 10 215 in Luxembourg. Costs due to morbidity range from € 102 per patient in Sweden and € 5178 in the UK resulting in total costs of € 1751-€ 12 611 per patient. Average weighted total costs per patient amount for € 6861-€ 6967 annually. In total, in 2012 approximately 4450 new cases of melanoma have been induced by sunbed use in the 31 included countries, which corresponds to 5.1% of all incident melanoma cases. National attributable melanoma costs range from € 1570 in Malta to € 11.1 million in Germany and sum up to an amount of € 32.5-€ 33.4 million for all countries. CONCLUSION: This article provides a first estimation on costs of melanoma in Europe. It illustrates the contribution of exposure to artificial ultraviolet light in the economic burden of malignant melanoma.

RESUMO

BACKGROUND: Sunbed use increases the risk of skin cancer. The Danish sunbed legislation (2014) did not include an age limit. AIM: To model skin cancer incidences and saved costs from potential effects of structural interventions on prevalence of sunbed use. MATERIALS AND METHODS: Survey data from 2015 were collected for 3999 Danes, representative for the Danish population in regards to age, gender and region. Skin cancer incidences were modelled in the Prevent program, using population projections, historic cancer incidence, sunbed use exposure and relative risk of sunbed use on melanoma. RESULTS: If structural interventions like an age limit of 18 years for sunbed use or complete ban had been included in the Danish sunbed legislation in 2014, it would have reduced the annual number of skin cancer cases with 455 or 4177, respectively, while for the entire period, 2014-2045 the total reductions would be 3730 or 81 887 fewer cases, respectively. The cost savings from an age limit or ban, respectively, are 9 and 129 millions € during 2014-2045. CONCLUSION: Legislative restrictive measures which could reduce the sunbed use exists. Danish politicians have the opportunity, supported by the population, to reduce the skin cancer incidence and thereby to reduce the future costs of skin cancer.

RESUMO

Indoor tanning is a known risk factor for skin cancer and is especially dangerous for adolescents. Some states have passed indoor tanning bans for minors, but business compliance with the bans is not well understood. Thus far, studies have assessed ban compliance in one or two states at a time. This study aimed to assess compliance with indoor tanning bans for minors and knowledge of dangers and benefits of tanning among indoor tanning businesses. Female research assistants posing as minors telephoned a convenience sample of 412 businesses in 14 states with tanning bans for minors under age 17 or 18. We evaluated differences in compliance by census region and years since ban was implemented and differences in reported dangers and benefits by compliance. Most (80.1%) businesses told the "minor" caller she could not use the tanning facilities. Businesses in the south and in states with more recent bans were less compliant. Among those (n = 368) that completed the full interview, 52.2% identified burning and 20.1% mentioned skin cancer as potential dangers. However, 21.7% said dangers were no worse than the sun and 10.3% denied any dangers. Stated benefits included vitamin D (27.7%), social/cosmetic (27.2%), and treats skin diseases (26.4%), with only 4.9% reporting no benefits. While most businesses followed the indoor tanning ban when a minor called, one-fifth did not. Many stated inaccurate health claims. Additional enforcement or education might increase compliance with indoor tanning bans and action is needed to prevent businesses from stating false health information.

RESUMO

BACKGROUND: Many young women experiment with using indoor tanning beds with some becoming regular users. There is a dearth of research focused on factors related to the development of regular tanning. This study was designed to gain an in-depth understanding of the experiences of a regular indoor tanning bed user for the purpose of discovering working hypotheses related to the development of this behavior. The article thesis is that initial interactions with tanning salon employees transmit insider knowledge that serves to encourage the regular use of indoor tanning beyond experimentation. METHODS: We used Spradley's ethnographic interviewing technique to conduct six iterative interviews with a key informant who was an active indoor tanning bed user and former salon employee. The research was completed in the United States in 2015. RESULTS: The informant described her experiences as a salon employee including her interactions with salon patrons. The informant was trained as a salon employee to talk about tanning as a complex process that requires multiple salon visits to achieve desired results and to develop rapport with salon patrons to be viewed as an important source of guidance and advice. In the informant's experience, indoor tanning users who viewed tanning as a complex process and felt connected to salon employees were more receptive to purchasing larger amounts of bulk tanning sessions and committing to purchasing salon memberships. CONCLUSIONS: Findings provide insights into our understanding of the development of regular tanning behavior and we propose working hypotheses about this behavior to be examined in future research. There are also implications for policy makers to reduce excessive tanning behaviors including considering point-of-sale regulations that limit sales techniques of salon employees and pricing restrictions.

RESUMO

BACKGROUND: Ultraviolet (UV) radiation is a human carcinogen and is associated with the development of skin cancer. The promotion of indoor tanning (IT) at fitness centres is of particular concern as it reinforces the idea that a tan is associated with health and fitness. The purpose of this study was to investigate the prevalence of IT in fitness centres, with an emphasis on determining the financial costs, adherence to regulations, and safety precautions. METHODS: Ten cities, representing 9 different Canadian provinces, were chosen for the study. From each province, a minimum of 20 and a maximum of 30 fitness centres were randomly selected from the Yellow Pages website. Each fitness centre was contacted by the principal investigator and inquiries were made from a consumer's perspective. RESULTS: Of the 203 gyms surveyed, 43% (88/203) offered tanning facilities. Of these, 10.23% (9/88) were found to be noncompliant with the provincial IT regulations for age and/or time between tanning sessions. INTERPRETATION: Despite the known risks of IT, not all fitness centres are compliant with provincial legislations regarding IT, and some continue to promote tanning access to minors.

RESUMO

This study uses individual-level longitudinal data from Iceland, a country that experienced a severe economic crisis in 2008 and substantial recovery by 2012, to investigate the extent to which the effects of a recession on health behaviors are lingering or short-lived and to explore trajectories in health behaviors from pre-crisis boom, to crisis, to recovery. Health-compromising behaviors (smoking, heavy drinking, sugared soft drinks, sweets, fast food, and tanning) declined during the crisis, and all but sweets continued to decline during the recovery. Health-promoting behaviors (consumption of fruit, fish oil, and vitamins/minerals and getting recommended sleep) followed more idiosyncratic paths. Overall, most behaviors reverted back to their pre-crisis levels or trends during the recovery, and these short-term deviations in trajectories were probably too short-lived in this recession to have major impacts on health or mortality. A notable exception is for binge drinking, which declined by 10% during the 2 crisis years, continued to fall (at a slower rate of 8%) during the 3 recovery years, and did not revert back to the upward pre-crisis trend during our observation period. These lingering effects, which directionally run counter to the pre-crisis upward trend in consumption and do not reflect price increases during the recovery period, suggest that alcohol is a potential pathway by which recessions improve health and/or reduce mortality.

RESUMO

OBJECTIVES: To investigate the association of contextual factors such as cost, tanning accessibility, regulations, or marketing and indoor tanning or tanning dependence. METHODS: One hundred thirty-nine college-aged female indoor tanners completed a questionnaire between 2009 and 2011. RESULTS: Higher scores on tanning dependence and assessment in the spring/summer (versus the fall/winter) were associated with more frequent indoor tanning in the last 30 days (ps < .05). More frequent indoor tanning, greater session length, and more trouble paying for tanning were associated with higher scores on tanning dependence (ps < .05). CONCLUSIONS: Public health research and practice could benefit from attention to such contextual factors as tanning cost and regulations regarding session length.

RESUMO

IMPORTANCE: Indoor tanning is widespread among young adults in the United States despite evidence establishing it as a risk factor for skin cancer. The availability of tanning salons on or near college campuses has not been formally evaluated. OBJECTIVE: To evaluate the availability of indoor tanning facilities on US college and university campuses (colleges) and in off-campus housing surrounding but not owned by the college. DESIGN, SETTING, AND PARTICIPANTS: This observational study sampled the top 125 US colleges and universities listed in US News and World Report. Investigators searched websites of the colleges and nearby housing and contacted them by telephone inquiring about tanning services. MAIN OUTCOMES AND MEASURES: Frequency of indoor tanning facilities on college campus and in off-campus housing facilities, as well as payment options for tanning. RESULTS: Of the 125 colleges, 48.0% had indoor tanning facilities either on campus or in off-campus housing, and 14.4% of colleges allow campus cash cards to be used to pay for tanning. Indoor tanning was available on campus in 12.0% of colleges and in off-campus housing in 42.4% of colleges. Most off-campus housing facilities with indoor tanning (96%) provide it free to tenants. Midwestern colleges had the highest prevalence of indoor tanning on campus (26.9%), whereas Southern colleges had the highest prevalence of indoor tanning in off-campus housing facilities (67.7%). Presence of on-campus tanning facilities was significantly associated with enrollment (P = .01), region (P = .02), and presence of a school of public health (P = .01) but not private vs public status (P = .18) or presence of a tobacco policy (P = .16). Presence of tanning facilities in off-campus housing was significantly associated with region (P = .002) and private vs public status (P = .01) but not enrollment (P = .38), tobacco policy (P = .80), or presence of a school of public health (P = .69). CONCLUSIONS AND RELEVANCE: Reducing the availability of indoor tanning on and around college campuses is an important public health target.

RESUMO

BACKGROUND & OBJECTIVE: Indoor tanning by adults under 35 years of age increases the risk of developing melanoma 59% to 75%. Cost is a major barrier limiting young adults from purchasing indoor tanning services. Our recent study by Boyers et al determined that 18 of 96 major universities, all in the eastern and southern United States, had university-sponsored debit cards with indoor tanning affiliations. These debit cards, which conveniently link with student identification (ID) cards, help with student living expenses and are often loaded with money by parents. By creating agreements with indoor tanning salon vendors, universities are endorsing a World Health Organization class I carcinogen. To expand the results of our previous study, we broadened our search to further assess universities in the western United States as well as Australia, New Zealand, Ireland, Canada, and the United Kingdom. METHODS: Using www.collegeboard.edu, we identified the 4 largest residential colleges in Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming. Additionally, we investigated the top international universities, utilizing www.topuniversities.com. Internet searches, phone calls, and email correspondence were used to determine if an institution had a student ID-linked debit card. Universities with affiliations to bank debit cards and cards that could only be used on campus were excluded. RESULTS: In the western United States, indoor tanning merchants were affiliated with University of Arizona, Embry-Riddle Aeronautical University: Prescott Campus, and the University of Denver student debit cards. Of the original 18 schools with affiliations according to the Boyers et al study, 2 universities no longer have agreements and 5 created agreements with additional tanning salons. Of 45 universities examined in our international search, no debit cards were discovered for off-campus purchases. Therefore, the concerning issue of university associations with tanning salons appears to be solely a domestic problem. CONCLUSIONS: Our findings indicate that the formation of financial agreements between universities and tanning salons is an ever-present and growing problem in the United States. Since Boyers et al, we have engaged in outreach efforts with alumni, faculty, administration, and local university cancer centers to terminate university ties with tanning salon vendors. Further advocacy efforts are critical to combat this dangerous association, reduce the frequency of skin cancer, and protect the health of young adults.
