Sunbed use among 64,000 Danish students and the associations with demographic factors, health-related behaviours, and appearance-related factors

Body image perception, smoking, alcohol use, indoor tanning, and disordered eating in young and middle-aged adults: findings from a large population-based Swedish study

BACKGROUND

Body image concerns may give rise to a multitude of risk behaviors, such as unhealthy weight control practices, disordered eating behaviors (e.g., compensatory purging or preoccupation with food), smoking, excessive alcohol intake, or sunbed use. However, the distribution of these risk behaviors across adulthood has rarely been studied.

METHODS

The aim of this study was to explore health risk behaviors as correlates of body image perception in a randomly selected study population of 30,245 individuals aged 30-66 in Stockholm, Sweden, utilizing data from the Stockholm Public Health Cohort. Bivariate correlations were explored and a hierarchic binary logistic regression analysis was performed.

RESULTS

The prevalence of body image discrepancy was higher among smokers and respondents displaying disordered eating behaviors. In contrast, alcohol and sunbed use were inversely correlated to body image discrepancy. Body mass index was the substantially strongest explanatory factor behind the observed variance in body image discrepancy, followed by loss-of-control eating. Notably, no major gender differences in body image perception were detected. Some unexpected patterns of association between variables other than body image perception, such as those between smoking, alcohol use, and sunbed use, were seen.

CONCLUSIONS

Overall, the patterns differ substantially from what has previously been found in adolescent and young adult samples, indicating that the synergy and aggregation of risk behaviors observed among younger individuals may not apply to adults aged 30-66.

Association of Indoor Tanning Regulations With Health and Economic Outcomes in North America and Europe

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.

Indoor tanning prevalence after the International Agency for Research on Cancer statement on carcinogenicity of artificial tanning devices: systematic review and meta-analysis

BACKGROUND

Exposure to artificial tanning devices is carcinogenic to humans, and government regulations to restrict or ban indoor tanning appear to be increasing.

OBJECTIVES

We evaluated changes in the international prevalence of indoor tanning among adolescents and adults after artificial tanning devices were classified as carcinogenic by the International Agency for Research on Cancer (IARC) in 2009.

METHODS

Systematic searches in PubMed and Web of Science databases were undertaken. Overall, 43 studies reporting 'ever' or 'past-year' indoor tanning exposure after 2009 were identified. We used metaregression analysis to evaluate the prevalence of indoor tanning over time. Random effects meta-analysis was used to summarize the prevalence of indoor tanning in adolescents and adults according to sex, region and presence of age prohibitions.

RESULTS

Global prevalence of indoor tanning in adolescents for 2013-2018 was 6·5% [95% confidence interval (CI) 3·3-10·6], 70% lower than the 22·0% (95% CI 17·2-26·8) prevalence for 2007-2012. Among adults, the prevalence was 10·4% (95% CI 5·7-16·3) for 2013-2018, a decrease of 35% from 18·2% for 2007-2012. Since 2009, the overall past-year prevalence among adolescents was 6·7% (95% CI 4·4-9·6) and 12·5% (95% CI 9·5-15·6) among adults. The prevalence of tanning indoors in the past year was similar in North America (adults, 12·5%; adolescents, 7·6%) and Europe (adults, 11·1%; adolescents, 5·1%). In 2009, three countries had regulations restricting indoor tanning, compared with 26 countries today.

CONCLUSIONS

Prevalence of indoor tanning has declined substantially and significantly in adolescents and adults since the 2009 IARC statement, reflecting the rise in regulations that limit this source of unnecessary exposure to carcinogenic ultraviolet radiation. What is already known about this topic? Indoor tanning is associated with an increased risk of melanoma. A meta-analysis of worldwide indoor tanning prevalence for 1986-2012 found a past-year prevalence of 18% in adolescents and 14% in adults, with higher prevalences during the period 2007-2012. Policies to regulate indoor tanning began to be implemented across the globe in 2009. Only one study carried out in the U.S.A. has evaluated the efficacy of such policies in reducing indoor tanning prevalence. What does this study add? For the period 2013-2018, we found indoor tanning prevalences of 6·7% in adolescents and 11·9% in adults. This implies a reduction in indoor tanning use of 70% in adolescents and 35% in adults during the last 10 years. Our study encourages policy makers to strengthen indoor tanning regulations that reduce sunbed use among the general population in order to produce maximum public health benefit.

Ultraviolet radiation exposure among Belgrade high school students: analysis of knowledge, attitudes and behaviour

BACKGROUND

The incidence of melanoma has been increasing worldwide. Extended UV exposure during childhood or adolescence significantly increases the probability of skin cancer in adulthood.

OBJECTIVE

The objective of this study was to analyse knowledge, attitudes and behaviour regarding exposure to natural and artificial UV radiation among Belgrade high school students.

METHODS

The study was conducted using a questionnaire among 549 students of 3rd and 4th grade (17 and 18 years of age) in four Belgrade high schools. The questionnaire had 32 questions: questions about gender, date and month of birth and parents' education, nine questions regarding sunbed use, nine questions regarding behaviour in the sun during summer months, four questions regarding personal and family history and skin phototype and seven questions regarding attitude and general knowledge about effects of UV radiation. Assessment of frequency rate and relative numbers was used as methods of descriptive statistics.

RESULTS

As many as 39% of participants had used a sunbed at least once, 38% plan on using it in the future. One quarter spends more than 3 hours in the sun on the beach during summer without any protection, and only one-third of participants had not experienced sunburn during last summer. Only one-half of students know what melanoma is, while 37% stated that they do not know.

CONCLUSION

General awareness of risk factors regarding sun exposure as well as general knowledge about melanoma is not on a high level among Belgrade high school students. Therefore, besides legislative measures, it is extremely important to conduct adequate education programmes in high schools.

Who, why, where: an overview of determinants of sunbed use in Europe

Although exposure to indoor tanning has been established as a clear risk factor for skin cancer, sunbeds are still commonly used in Europe. Understanding the determinants of sunbed use in Europe is key to plan educational interventions, behavioural strategies and legislative measures, which should be tailored to subgroups with different risk profiles. Evidences show that the typical sunbed users in Europe are young-adult women, with intermediate skin type, a current employment and a medium/high socio-economic status. Typical users display sun-seeking behaviours and other risky behaviours such as smoking. Indoor tanning seems more common in northern than southern Europe. However, sunbed use remains common in fair-skinned individuals and among adolescents/pre-adolescents. Commonly reported reasons for sunbed use in Europe include aesthetic motives (i.e. looking attractive), the pursue of a prevacation tan, the influence of peers/parents engaging in the same habit, and the treatment of health conditions. The most commonly reported places to get an artificial tan in Europe are tanning studios and beauty salons. However, sunbeds are also available in sport venues, such as swimming pools and gyms, hotels and private houses. All these factors should be taken into account when planning educational, behavioural and legislative interventions to reduce the popularity of artificial tanning in Europe.

Skin cancer projections and cost savings 2014-2045 of improvements to the Danish sunbed legislation of 2014

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.

Sunbed use 2007-2015 and skin cancer projections of campaign results 2007-2040 in the Danish population: repeated cross-sectional surveys

OBJECTIVE

To evaluate the effect of the Danish Sun Safety Campaign 2007-2015 on the prevalence of sunbed use and to model future effects on the skin cancer incidences 2007-2040.

DESIGN

The study has a repeated, cross-sectional design.

SETTING

Exposure to ultraviolet radiation is the main risk factor for skin cancer. Denmark has the highest prevalence of sunbed use reported and one of the highest incidences of skin cancer worldwide.

PARTICIPANTS

During 2007-2015, survey data were collected for 37 766 Danes, representative of the Danish population with regards to age, gender and region.

INTERVENTIONS

In 2007, an ongoing long-term antisunbed campaign was launched in Denmark.

PRIMARY AND SECONDARY OUTCOME MEASURES

Sunbed use was evaluated by annual cross-sectional surveys. Skin cancer incidence was modelled in the Prevent programme, using population projections, historic cancer incidence, sunbed use exposure and relative risk of sunbed use on melanoma.

RESULTS

The prevalence of recent sunbed use in Denmark was reduced from 32% and 18% to 13% and 8% for women and men, respectively. The campaigns results during 2007-2015 are estimated to reduce the number of skin cancer cases from more than 5000 (746malignant melanoma, 1562 SCC, 2673 BCC) totally during 2007-2040. Keeping the 2015 level of sunbed use constant by continued campaign pressure or introduction of structural interventions would potentially prevent more than 750 skin cancer cases annually in 2040 and 16 000 skin cancer cases in total during 2007-2040.

CONCLUSION

We have shown the value of prevention and of long-term planning in prevention campaigning. Sunbed use was reduced significantly during 2007-2015 and further reductions are possible by structural interventions. Consequently, significantly fewer skin cancer cases are anticipated during 2007-2040. The Danish Parliament has population support to enforce structural interventions to avoid a large burden of this disease.
