Assessment of knowledge of melanoma risk factors, prevention, and detection principles in Texas teenagers

Knowledge and attitudes of UK university students in relation to ultraviolet radiation (UVR) exposure and their sun-related behaviours: a qualitative study

OBJECTIVES

To explore whether knowledge about the harms of ultraviolet radiation (UVR) influences UK university students' sun-related behaviours and examine in depth their attitudes towards: sun protection, natural and artificial tanning behaviours.

DESIGN

Qualitative methodology with 15 semistructured, individual interviews. Thematic analysis using the Framework Method with analyst triangulation and member validation.

SETTING

One university in the West Midlands, UK.

PARTICIPANTS

15 Caucasian male (n=4) and female (n=11) students, aged 18-22 years, from a UK university. Participants were recruited using convenience sampling from the university's main campus followed by purposive sampling for: gender, course and sun-related behaviours.

RESULTS

Five main themes emerged: (1) knowledge of UVR; (2) sun-protection practices; (3) attitudes towards tanning; (4) external influences and (5) internal influences. All students knew the associated skin cancer risks from the sun and sunbed use, but this did not appear an important influence in their sun-related behaviours. Body image strongly motivated sun-protection practices and the desire to tan naturally or artificially, across both genders. However, participants' final decision-making appeared to be influenced by their beliefs that practising known harmful sun-related behaviours would not affect them or the perceived susceptibility to sunburn. Beliefs about sunbathing and sunscreen use prompted improper use of sun protection and inadvertently caused more harmful practices. Participants' peers, family and the media had dual roles influencing the development of attitudes towards sun protection and tanning, which contributed to how participants behaved in the sun and their engagement in tanning methods.

CONCLUSIONS

Knowledge about the risk of skin cancer associated with UVR did not strongly influence sun-related behaviours, whereas body image appeared as a key motivator. Attitudes towards sun protection and tanning stemmed from the media, peers and family, and particularly from childhood habits. Public health strategies may benefit from appearance-related skin cancer prevention campaigns, encouraging safer parental sun-related habits and correcting sun-related misconceptions.

Brazilian consensus on photoprotection

Brazil is a country of continental dimensions with a large heterogeneity of climates and massive mixing of the population. Almost the entire national territory is located between the Equator and the Tropic of Capricorn, and the Earth axial tilt to the south certainly makes Brazil one of the countries of the world with greater extent of land in proximity to the sun. The Brazilian coastline, where most of its population lives, is more than 8,500 km long. Due to geographic characteristics and cultural trends, Brazilians are among the peoples with the highest annual exposure to the sun. Epidemiological data show a continuing increase in the incidence of non-melanoma and melanoma skin cancers. Photoprotection can be understood as a set of measures aimed at reducing sun exposure and at preventing the development of acute and chronic actinic damage. Due to the peculiarities of Brazilian territory and culture, it would not be advisable to replicate the concepts of photoprotection from other developed countries, places with completely different climates and populations. Thus the Brazilian Society of Dermatology has developed the Brazilian Consensus on Photoprotection, the first official document on photoprotection developed in Brazil for Brazilians, with recommendations on matters involving photoprotection.

International prevalence of indoor tanning: a systematic review and meta-analysis

IMPORTANCE

Indoor tanning is a known carcinogen, but the scope of exposure to this hazard is not known.

OBJECTIVE

To summarize the international prevalence of exposure to indoor tanning.

DATA SOURCES

Studies were identified through systematic searches of PubMed (1966 to present), Scopus (1823 to present), and Web of Science (1898 to present) databases, last performed on March 16, 2013. We also hand searched reference lists to identify records missed by database searches and publicly available data not yet published in the scientific literature.

STUDY SELECTION

Records reporting a prevalence of indoor tanning were eligible for inclusion. We excluded case-control studies, reports with insufficient study information, and reports of groups recruited using factors related to indoor tanning. Two independent investigators performed searches and study selection. Our search yielded 1976 unique records. After exclusions, 161 records were assessed for eligibility in full text, and 88 were included.

DATA EXTRACTION AND SYNTHESIS

Two independent investigators extracted data on characteristics of study participants, inclusion/exclusion criteria, data collection format, outcomes, and statistical methods. Random-effects meta-analyses were used to summarize the prevalence of indoor tanning in different age categories. We calculated the population proportional attributable risk of indoor tanning in the United States, Europe, and Australia for nonmelanoma skin cancer (NMSC) and melanoma.

MAIN OUTCOMES AND MEASURES

Ever and past-year exposure to indoor tanning.

RESULTS

The summary prevalence of ever exposure was 35.7% (95% CI, 27.5%-44.0%) for adults, 55.0% (33.0%-77.1%) for university students, and 19.3% (14.7%-24.0%) for adolescents. The summary prevalence of past-year exposure was 14.0% (95% CI, 11.5%-16.5%) for adults, 43.1% (21.7%-64.5%) for university students, and 18.3% (12.6%-24.0%) for adolescents. These results included data from 406 696 participants. The population proportional attributable risk were 3.0% to 21.8% for NMSC and 2.6% to 9.4% for melanoma, corresponding to more than 450 000 NMSC cases and more than 10 000 melanoma cases each year attributable to indoor tanning in the United States, Europe, and Australia.

CONCLUSIONS AND RELEVANCE

Exposure to indoor tanning is common in Western countries, especially among young persons. Given the large number of skin cancer cases attributable to indoor tanning, these findings highlight a major public health issue.

A simple intervention to reinforce awareness of tanning bed use and skin cancer in non-medical skin care professionals in Southern California

BACKGROUND

(i) To assess the baseline knowledge of non-medical skin care professionals (estheticians, cosmetologists, massage therapists) on tanning bed use and its association with melanoma; and (ii) to provide preliminary evidence of the potential impact of a fast and simple educational intervention on tanning beds and melanoma on the awareness of non-medical skin care professionals towards skin cancer prevention.

METHODS

A pre-intervention survey was administered to non-medical skin care professional at salons or spas in Southern California to assess baseline knowledge on tanning and skin cancer. This was followed immediately by a 10-minute oral presentation on tanning bed use and its association with melanoma. One month later, a post-intervention survey was distributed to individuals who attended the initial oral presentation.

RESULTS

Significant changes pre- and post-intervention were found in non-medical skin care professionals' answer responses to the following: (i) increased speaking to clients about cancer risk with tanning bed use 42-66% (OR 2.44; 95% CI 1.39, 4.30)]; (ii) decreased personal tanning bed use (23-15% [OR 0.61; 95% CI 0.37, 1.00]); and (iii) decreased belief that tanning beds are an excellent cosmetic tool (29-20% [OR 0.60; 95% CI 0.38, 0.96]).

CONCLUSION

This study provides preliminary evidence that non-medical skin care professionals could be an important source of primary prevention information for reducing the burden of melanoma.

Assessment of knowledge of skin cancer prevention and its relation with sun exposure and photo protection amongst gym academy members on the south of Santa Catarina, Brazil

BACKGROUND

Skin cancer is the most frequent neoplasia in several parts of the world and also in Brazil. There is evidence of an increase in morbidity and mortality from skin cancer. Although the incidence of skin cancer is increasing, it is estimated that 45% of all preventable cancers worldwide are skin neoplasias. Several studies have emphasized the need for campaigns to encourage sun protection.

OBJECTIVE

To assess the knowledge about skin cancer prevention and its association with sun exposure and photo protection in gym members.

METHODS

We conducted a cross-sectional, descriptive and quantitative study during January to July 2009, including gym members of both sexes in the city of Criciuma. A self-administered questionnaire was used. The statistical analysis was conducted in a descriptive way in regards to the absolute and relative frequencies of the variables under study.

RESULTS

Of the 317 questionnaires studied, 62% were from women and 38% from men. Skin types II and III predominated, and the average age was 27.6 years. 94.3% of the participants reported that they had heard about the risks of sun exposure, mostly in terms of skin cancer risk (80.8%). Most participants, especially women, reported some form of sun protective measure.

CONCLUSION

The population studied, similar to that in other regions of Brazil and the world, is aware of the risks of excessive sun exposure and skin cancer prevention, but has not yet incorporated appropriate sun protection measures into their daily habits.

Improving understanding about tanning behaviors in college students: a pilot study

OBJECTIVE

Melanoma is the second most common cancer diagnosed among 15- to 29-year-olds. This pilot study assessed behaviors, barriers, and beliefs relevant to sun exposure and protective behaviors.

PARTICIPANTS

The sample comprised 153 undergraduate students at a large state university in western New York.

METHODS

Participants completed an online survey about sun safety habits, barriers to using sunblock, and beliefs about tanning and sun exposure.

RESULTS

Response rate was 90.8% (n = 139). Most students (87.8%) reportedly spent ≥ 3 hours per day outside in the summer, but only 17.3% reported always using sunblock during this time. Sixty percent reported recent indoor tanning and 41% reported more than 10 lifetime sunburns. The greatest barrier to using sunblock was forgetting (84.2%).

CONCLUSIONS

Demographics coupled with inconsistent and low levels of sunblock use, high annual prevalence of indoor tanning, and multiple lifetime sunburns indicate that this sample is at high risk for skin cancer.

Skin cancer-related prevention and screening behaviors: a review of the literature

Primary prevention and early detection continue to be of paramount importance in addressing the public health threat of skin cancer. The aim of this systematic review was to provide a comprehensive overview of the prevalence and correlates of skin cancer-related health behaviors in the general population. To achieve this aim, 91 studies published in international peer-reviewed journals over the past three decades were reviewed and synthesized. Reported estimates of sunscreen use varied considerably across studies, ranging from 7 to 90%. According to self-report, between 23 and 61% of individuals engage in skin self-examination at least once per year, and the documented prevalence of annual clinical skin examination ranges from 8 to 21%. Adherence to sun protection and screening recommendations is associated with a range of factors, including: female gender, sun-sensitive phenotype, greater perceived risk of skin cancer, greater perceived benefits of sun protection or screening, and doctor recommendation for screening. The literature suggests that a large proportion of the general population engage in suboptimal levels of sun protection, although there is substantial variability in findings. The strongest recommendation to emerge from this review is a call for the development and widespread use of standardized measurement scales in future research, in addition to more studies with a population-based, multivariate design. It is also recommended that specific targeted interventions are developed to increase the prevalence of preventative and early intervention behaviors for the control of skin cancer.

Nurse practitioners' knowledge and practice regarding malignant melanoma assessment and counseling

PURPOSE

To evaluate the knowledge base and clinical practices of nurse practitioners (NPs) within the states of Illinois and California regarding malignant melanoma.

DATA SOURCES

Data sources included responses to a 57-item self-administered questionnaire and 15-item demographic survey. A convenience sample of 93 certified NPs from Illinois and California, aged 27-68 years, participated in the study. Participants responded to questions relating to knowledge of malignant melanoma preventive measures, risk factors, barriers to performing malignant melanoma assessments, and lesion recognition.

CONCLUSIONS

Overall, the NPs in this study demonstrated adequate knowledge about malignant melanoma but conducted general skin and malignant melanoma assessments less than half of the time and provided patient teaching about preventive measures and risk factors only occasionally. While California NPs demonstrated significantly greater knowledge about malignant melanoma than the Illinois NPs, they performed less skin and malignant melanoma assessments and provided less teaching. The most frequently cited barrier to performing malignant melanoma examinations for both states was time constraints.

IMPLICATIONS FOR PRACTICE

NPs can play a pivotal role in reducing the morbidity and mortality of malignant melanoma through competent skin assessments and patient education and encouraging patients to pursue healthy lifestyles. Improving NPs' assessment skills and knowledge about malignant melanoma, however, is critical to achieving this goal.

Screening and early detection of skin cancer

Skin cancer is the most common type of cancer in the United States. US incidence of malignant melanoma is increasing faster than any other type of cancer. To minimize increasing morbidity and mortality rates, it is imperative that appropriate screening and early detection of skin cancer become more widespread. All physicians who see patients clinically have the potential for detecting skin cancers. The scope of skin cancer as a health-care problem is discussed. Evidence for the effectiveness and necessity of skin cancer screening and early detection is presented. Costs of screening and detection are discussed in relation to impact on treatment costs and overall costs of skin cancer burden. Current methods and recommendations for skin cancer screening and detection are reviewed, especially with regard to individuals and populations that may require more specialized or intensive screening and follow-up. Newer approaches involving instrument-assisted screening and detection of skin cancer are under intense development, and these exciting emerging technologies are reviewed.

Photoprotection in adolescence

Physical changes and the establishment of personal values are characteristics of adolescence. Despite being well informed regarding sun protection and the skin cancer risks related to sun exposure, teenagers usually make little use of sunscreens and remain out in the sun for long periods. Besides the social appeal and the impression that a nice tan provides a healthy appearance, the tendency to deny long-term risks seems to influence sun exposure behaviors in this life period. Due to the strong relation between skin cancer and sun exposure in childhood and adolescence, it is important to encourage the adoption of photoprotection measures early in life. Adolescents have difficulty accepting guidance through official educational messages, and very few of them follow family recommendations. Celebrities, fashion, and the entertainment industry exert a greater influence on their choices. Thus, it is fundamental to incorporate photoprotection counseling into the medical routine, in an adolescent-driven way. This article reviews peculiarities of sun protection in adolescence and discusses the type of advice to be given to patients in this age group.

Indoor tanning by adolescents: prevalence, practices and policies

Despite known acute and chronic health effects from the use of indoor tanning, including the potential for all forms of skin cancer, the practice is popular in the United States (US) and Europe. A review of the scientific literature that examines adolescents and indoor tanning use was undertaken, summarising what is known about prevalence and practices among adolescents, characteristics associated with adolescent use, and policies that regulate adolescent access to indoor tanning facilities. The prevalence of indoor tanning is consistently found to be higher among girls than boys and to increase with age in both Europe and the US. An examination of other demographic characteristics, skin cancer risk factors, knowledge, attitudes and social factors points to higher prevalence of the behaviour among adolescents with positive attitudes towards tans and whose friends or parents also tan indoors. Adolescent access to indoor tanning is rarely regulated in the US or Europe, and where regulations exist, business compliance is low. In addition, businesses actively market their product to adolescents as they organise to limit further regulations prohibiting adolescent access. Pricing, licensure, advertising restrictions and media campaigns, in combination with adolescent-targeted interventions, are possible strategies that could be tested for their effectiveness to reduce adolescent indoor tanning use. Harm reduction policies, such as eye protection, that reduce risk for adolescents who choose to tan indoors, are also important.

What influences university students' intentions to practice safe sun exposure behaviors?

PURPOSE

To apply Protection Motivation Theory to examine adolescents' intentions to perform safe sun exposure behaviors.

METHODS

A total of 239 students (aged 18 to 22 years) from two British universities were recruited to the study. The majority of participants were white (68%), 29% were classified as Asian, and the remaining 3% were Afro-Caribbean. Participants completed a questionnaire comprising items examining the components of Protection Motivation Theory. Intention to perform safe sun exposure behaviors was examined by asking participants to indicate their agreement with five statements about future sun exposure behaviors.

RESULTS

Hierarchical multiple regression analysis revealed that the threat appraisal components of Protection Motivation Theory were stronger predictors of intention to perform safe sun exposure behaviors (accounting for 15% of the variance) than the coping appraisal components (accounting for 3% of the variance). However, previous performance of similar behaviors emerged as the strongest overall predictor of intention to perform safe sun exposure behaviors (beta = -.514, p < .01), followed by perceived vulnerability to developing skin cancer (beta = .232, p < .01) and practicing skin and naevi self examination behaviors (beta = -.172, p < .01).

CONCLUSIONS

The results suggest that a strategic sun protection education campaign is necessary with the aim of encouraging adaptive sun behaviors by emphasizing the risk of skin cancer associated with sunburn.

Levels and correlates of knowledge about cancer risk factors among 13,293 public school students in Morelos, Mexico

BACKGROUND

Data on young people's knowledge about cancer prevention are not currently available for many populations, including Mexican young people, although cancer is the second most common cause of death among the Mexican population.

METHODS

A questionnaire was applied to 13,293 public school students aged 11-24 years in Morelos, Mexico. A knowledge-based scale was constructed from survey answers about risk factors for cancer. Data were analyzed using multivariate logistic multinomial models.

RESULTS

Knowledge levels were low: 78% of male and 74% of female students had only wrong answers to questions about risk factors for cancer. A significant dose-response gradient was observed between age and knowledge of cancer risk factors (P < 0.001), with a higher prevalence in young women at all ages (female students OR 4.6, 95% CI 3.81-5.66). Students 18 years old and older knew more than 13-year-olds (OR = 2.39; 95% CI 1.89-3.01). Sexually active students (OR 2.10; 95% CI 1.70-2.58), especially those who consistently used condoms (OR 2.84; 95% CI 1.00-8.07), knew more about cancer prevention. Tobacco smoking was the most frequently recognized cancer risk factor, and smokers also recognized this as an important cause of cancer (OR 1.37; 95% CI 1.44-2.52).

CONCLUSIONS

Our results reveal a poor level of knowledge about cancer prevention among adolescents. These data are the first step in the development of an intervention based on empirical findings that will be susceptible to evaluation.

Avaliação dos hábitos de exposição ao sol e de fotoproteção dos universitários da Região Metropolitana de Porto Alegre, RS

FUNDAMENTOS: Sabe-se que a mudança de hábito da população mundial com relação à exposição ao sol provocou aumento da incidência de câncer da pele nas últimas décadas. Tais informações são especialmente relevantes na Região Sul, na qual há maior prevalência da população branca, mais propensa aos danos solares, em comparação ao restante do Brasil. OBJETIVOS: Avaliar os hábitos de exposição ao sol e de fotoproteção dos universitários da Região Metropolitana de Porto Alegre no período de julho a setembro de 2001. MÉTODOS: Foram respondidos 1.030 questionários por universitários residentes na Região Metropolitana de Porto Alegre. RESULTADOS: Nos finais de semana, 38,4% dos estudantes permanecem ao sol entre duas e seis horas diárias. Durante o verão, 43,7% deles se expõem ao sol entre as 10 e as 15h; 85% dos estudantes afirmam usar filtro solar, mas 65% não o usam ao praticar esportes ao ar livre. CONCLUSÕES: Os autores observaram que a maioria dos universitários se expõe excessivamente ao sol, em horários impróprios e sem efetiva proteção solar.

Tanning Devices - Fast Track to Skin Cancer?

The use of UVB and/or UVA emitting devices for cosmetic tanning is widespread in Western populations including young people and is especially prevalent in females. Several epidemiological studies, although not all, have shown a significant relationship between the use of tanning devices and malignant melanoma after, in some cases, adjustment for confounding factors such as solar ultraviolet radiation (UVR) exposure. A relationship between solar exposure, especially intermittent exposure, and malignant melanoma is well established so it is not surprising that a similar connection has been reported for the use of tanning devices. Several epidemiological studies show that childhood exposure to sunlight is a risk factor for malignant melanoma and this may also be the case for the use of tanning devices, especially if sunburns are obtained. Some studies have evaluated the relationship between the use of tanning devices and non-melanoma skin cancer and at least one has suggested an association. The use of tanning devices by a substantial minority of young people is a worrying trend in terms of a likely increased incidence of malignant melanoma, and possibly non-melanoma cancers in the future. Although two recent reviews by epidemiologists conclude that a clear link between tanning devices and malignant melanoma is yet to be proven, there is a strong case for effective legislation to prohibit the use of tanning devices by people under 18 yr of age.

Tanning facility use: are we exceeding Food and Drug Administration limits?

BACKGROUND

The US Food and Drug Administration (FDA) recommends exposure limits for tanning bed use. Tanning patrons may not be following these recommendations and may be overexposed to damaging ultraviolet radiation (UV).

OBJECTIVE

This study was conducted to assess tanning patrons' adherence to FDA-recommended exposure limits and to measure the amount of UVA and UVB radiation emitted by tanning beds.

METHODS

A community-based survey was administered during routine state inspections of North Carolina tanning facilities (n = 50). At each facility, patron records were randomly selected (n = 483) for a survey of exposure records, and UVA and UVB outputs were measured for each tanning bed.

RESULTS

The recommended limits were exceeded by 95% of patrons, and 33% of patrons began tanning at the maximum doses recommended for maintenance tanning. Average tanning bed output was 192.1 W/m(2) UVA and 0.35 W/m(2) erythemally weighted UVB.

CONCLUSIONS

Interventions for tanning bed operators and patrons are needed to increase compliance with federally recommended exposure limits.

Melanoma etiology: where are we?

Melanoma incidence rates are rising rapidly, particularly in older men. Older men are also more likely to have thick melanomas, which confer high mortality and morbidity. The reasons for the rate of increase are not known; increasing sun and UV exposure, however, is the major hypothesized explanation. In the past several years, two major susceptibility genes for melanoma, CDKN2A and CDK4, have been identified, but the two genes together account for a minority of familial melanoma. Other high-risk susceptibility genes are being sought actively. Genetic epidemiologic studies suggest that penetrance of each of the two identified genes is altered by other factors, either genetic or environmental. Epidemiologic studies have also identified other major host factors important in the development of melanoma. In European, North American, and Australian populations, the presence of clinically identified dysplastic nevi confers greatly increased risk of melanoma. A new measure of sun exposure, based on individual residential history, confers substantially increased risk of melanoma. Recent surveys of sun behavior in the US reveal extensive sunburning and use of tanning beds in adolescents and adults. Sun protective behaviors are not as prevalent as in Australia, where population rates of melanoma are stabilizing.

Use of indoor tanning sunlamps by US youth, ages 11-18 years, and by their parent or guardian caregivers: prevalence and correlates

BACKGROUND

Tanning parlors have become common in the United States. Artificial ultraviolet radiation exposure from this source may be harmful and may increase the risk of melanoma, particularly when done for recreational purposes during childhood and early adult years. Population-based data on the prevalence and correlates of this activity is important in the evaluation of potential public health interventions for skin cancer prevention.

STUDY DESIGN

In 1998, we conducted a population-based telephone survey of youth and their primary caregiver. The sample (N = 1192) was weighted to represent the population of US youth living in households with a primary caregiver. Interviewers used a standardized questionnaire to document the characteristics of the participant and their practices, attitudes, and experiences regarding ultraviolet exposures. METHOD OF ANALYSIS: Weighted prevalence and adjusted prevalence odds ratios (aPOR) and 95% confidence interval (95% CI) were estimated. Independent factors were evaluated with multivariate logistic regression.

RESULTS

Ten percent of youth and 8% of their primary caregivers used indoor tanning sunlamps in the previous year. Thirty percent of the youth whose caregivers used indoor tanning sunlamps did so themselves as well. Independent predictors associated with indoor tanning sunlamp use were as follows: age 17 to 18 years (aPOR = 11.1; 95% CI: 5.0, 25.0); female (aPOR = 8.3; 95% CI: 3.6, 19.2); having a parent who used indoor tanning sunlamps in the previous year (aPOR = 8.7; 95% CI: 4.0, 18.9); nonuser of Sun Protection Factor 15 sunscreen at the beach or pool (aPOR = 1.9; 95% CI: 1.0, 3.4); and low sun sensitivity (aPOR = 2.3; 95% CI: 1.0, 5.3).

CONCLUSION

A substantial minority of American youth engages in indoor tanning. However, it is particularly prevalent among older youth, girls, and youth whose parents themselves use indoor tanning sunlamps. The knowledge of these trends may help focus public health initiatives.
