Abstract
Solar particle events (SPEs) are short-lived bursts of high-energy particles from the solar atmosphere and are widely recognized as posing significant economic risks to modern society. Most SPEs are relatively weak and have minor impacts on the Earth's environment, but historic records contain much stronger SPEs which have the potential to alter atmospheric chemistry, impacting climate and biological life. The impacts of such strong SPEs would be far more severe when the Earth's protective geomagnetic field is weak, such as during past geomagnetic excursions or reversals. Here, we model the impacts of an extreme SPE under different geomagnetic field strengths, focusing on changes in atmospheric chemistry and surface radiation using the atmosphere-ocean-chemistry-climate model SOCOL3-MPIOM and the radiation transfer model LibRadtran. Under current geomagnetic conditions, an extreme SPE would increase NOx concentrations in the polar stratosphere and mesosphere, causing reductions in extratropical stratospheric ozone lasting for about a year. In contrast, with no geomagnetic field, there would be a substantial increase in NOx throughout the entire atmosphere, resulting in severe stratospheric ozone depletion for several years. The resulting ground-level ultraviolet (UV) radiation would remain elevated for up to 6 y, leading to increases in UV index up to 20 to 25% and solar-induced DNA damage rates by 40 to 50%. The potential evolutionary impacts of past extreme SPEs remain an important question, while the risks they pose to human health in modern conditions continue to be underestimated.

Abstract
Ultraviolet radiation (UVR) exposure is the primary modifiable risk factor for melanoma. Wearable UVR sensors provide a means of quantifying UVR exposure objectively and with a lower burden than self-report measures used in most research. The purpose of this study was to evaluate the relationship between detected UVR exposure and reported sunburn occurrence. In this study, a UVR monitoring device was worn by 97 parent-child dyads during waking hours for 14 days to measure instantaneous and accumulated UVR exposure. The results showed that the participants' total UVR exposure was associated with reported sunburn after adjusting for Fitzpatrick skin type and geographic location. It was observed that one standard erythemal dose (SED) increase in the participants' daily total UVR exposure was associated with reported sunburn (an odds ratio (OR) of 1.26 with a 95% CI of 1.13 and 1.41, and p < 0.001 for parents and an OR of 1.28 with a 95% CI of 1.12 and 1.47, and p < 0.001 for children). A one-SED increase in the participants' UVR exposure from 10 am to 4 pm was also associated with reported sunburn (an OR of 1.31 with a 95% CI of 1.15 and 1.49, and p < 0.001 for parents and an OR of 1.33 with a 95% CI of 1.12 and 1.59, and p = 0.001 for children). We found that elevated UVR exposure recordings measured by the UVR sensor were associated with reported sunburn occurrence. Future directions for wearable UVR sensors may include their use as an intervention tool to support in-the-moment sunburn prevention.

Abstract
Athletes who compete in outdoor sports can receive potentially harmful levels of solar ultraviolet radiation (UVR). Rowing is a popular outdoor sport that takes place during the peak UVR season. Using electronic dosimeters attached to the shoulder strap of the rower's uniform, this study aimed to quantify the real-time solar UVR exposure experienced by high school rowers during competition. We measured personal UVR exposure (PE) during the time spent on the water in order to compete in a single rowing-race (race-time), when rowing administrators are responsible for athletes' wellbeing. Data collection took place in Aotearoa (New Zealand) at Lake Ruataniwha (44.28°S, 170.07°E), during two consecutive rowing seasons (December-February 2018-19 and 2019-20). Analysis of dosimeter data generated from 56 race-times over five regattas revealed a median personal UVR exposure (PE) of 1.15 standard erythemal dose (SED), where 1 SED is defined as an effective radiant exposure of 100 Jm-2. Mean race-time was 46 min. Over two-thirds of race-times (69.6%) exceeded the Australian Radiation Protection and Nuclear Safety Agency recommendation of 1 SED being considered safe for most people in a day. An exposure of 1.5-3.0 SED produces perceptible erythema for people with light coloured skin and the lower parameter of 1.5 SED was exceeded in 14 (25.0%) of the race-times. By regatta, the median SED/h ranged from 0.96-2.40 and the median percentage of total concurrent ambient UVR ranged from 17 to 31%. Our results indicate that rowing is a high UVR sport and that races outside of peak UVR times also warrant the use of sun protection even when the UVI < 3. Given that acute and cumulative UVR exposure are recognised risk factors in the development of ocular diseases and skin cancers later in life, risk management guidelines for competitive school rowing will be incomplete until a long-term approach to well-being is considered and comprehensive sun protection measures adopted.

Abstract
BACKGROUND Scalp and neck (SN) melanoma confers a worse prognosis than melanoma of other sites but little is known about its determinants. We aimed to identify associations between SN melanoma and known risk genes, phenotypic traits, and sun exposure patterns. METHODS Participants were cases from the Western Australian Melanoma Health Study (n = 1,200) and the Genes, Environment, and Melanoma Study (n = 3,280). Associations between risk factors and SN melanoma, compared with truncal and arm/leg melanoma, were investigated using binomial logistic regression. Facial melanoma was also compared with the trunk and extremities, to evaluate whether associations were subregion specific, or reflective of the whole head/neck region. RESULTS Compared with other sites, increased odds of SN and facial melanoma were observed in older individuals [SN: OR = 1.28, 95% confidence interval (CI) = 0.92-1.80, P trend = 0.016; Face: OR = 4.57, 95% CI = 3.34-6.35, P trend < 0.001] and those carrying IRF4-rs12203592*T (SN: OR = 1.35, 95% CI = 1.12-1.63, P trend = 0.002; Face: OR = 1.29, 95% CI = 1.10-1.50, P trend = 0.001). Decreased odds were observed for females (SN: OR = 0.49, 95% CI = 0.37-0.64, P < 0.001; Face: OR = 0.66, 95% CI = 0.53-0.82, P < 0.001) and the presence of nevi (SN: OR = 0.66, 95% CI = 0.49-0.89, P = 0.006; Face: OR = 0.65, 95% CI = 0.52-0.83, P < 0.001). CONCLUSIONS Differences observed between SN melanoma and other sites were also observed for facial melanoma. Factors previously associated with the broader head and neck region, notably older age, may be driven by the facial subregion. A novel finding was the association of IRF4-rs12203592 with both SN and facial melanoma. IMPACT Understanding the epidemiology of site-specific melanoma will enable tailored strategies for risk factor reduction and site-specific screening campaigns.

Abstract
In this article, we summarize the research that eventually led to the classification of the full ultraviolet (UV) radiation spectrum as carcinogenic to humans. We recall the pioneering works that led to the formulation of novel hypotheses on the reasons underlying the increasing burden of melanoma in light-skinned populations. It took long before having compelling evidence on the association between UV and melanoma, in particular, the importance of UV exposure during childhood for both the occurrence of melanoma and death. The role of UVA was established only after 2005. If molecular lesions caused by UV radiation are better known, the precise mechanism by which UV exposure drives melanoma occurrence and progression still needs to be elucidated. More research on the UV-melanoma relationships has led to more evidence-based sun-protection recommendations, especially for children, and to effective control of the artificial UV tanning fashion. Since around 1985-1995, the mortality because of melanoma has started to decrease in younger age groups in most light-skinned populations. If sun protection among children remain on top of public health agendas, there is a fairly great chance that melanoma mortality will stabilize and steadily decrease in all light-skinned populations. The introduction of effective therapies against metastatic disease will improve this reversal in mortality trends.

Abstract
BACKGROUND The incidence of malignant melanoma is increasing faster than any other cancer, and it is now the second most common cancer in young adults. Most skin cancer prevention campaigns are based on the hypothesis that improved skin cancer knowledge leads to a change in sun-related behaviour. AIM The aim of this study was to analyse the relationship of good skin cancer knowledge in a high knowledge group-medical students-with sun-related behaviours and tanning attitudes in Ireland. METHODS A cross-sectional survey was conducted on university students studying medicine in a single institution. RESULTS The final analyses included 312 complete questionnaires. Two hundred three (65.27%) were female, and 108 (34.73%) were male. The majority (65.06%) were aged 21-25 years. The mean skin cancer knowledge score was 89.77%. There was a positive attitude to tanning with 201 (64.63%) participants feeling more attractive with a suntan and 174 (55.94%) feeling better about themselves with a suntan. More than half of participants, 196 (54.17%), got a suntan last year, 171 (54.81%) participants sunbathed, 188 (60.26%) got sunburned and 30 (9.61%) reported using sunbeds previously. Those with a positive attitude to tanning were more likely to sunbath, suntan and get sunburned. High skin cancer knowledge scores were positively associated with high-risk sun behaviours (Spearman's rank correlation coefficient = 0.156, P = 0.006). CONCLUSION Urgent action is needed to promote skin cancer prevention. This study adds to the evidence that melanoma prevention strategies should preferentially target tanning attitudes rather than skin cancer knowledge.

Abstract
BACKGROUND Melanoma develops as the result of complex interactions between sun exposure and genetic factors. However, data on these interactions from prospective studies are scant. OBJECTIVES To quantify the association between ambient and personal ultraviolet exposure and incident melanoma in a large population-based prospective study of men and women residing in a setting of high ambient ultraviolet radiation, and to examine potential gene-environment interactions. METHODS Data were obtained from the QSkin Sun and Health Study, a prospective cohort study of men and women aged 40-69 years, randomly sampled from the Queensland population in 2011. Participants were genotyped and assessed for ultraviolet exposure. RESULTS Among participants with genetic data (n = 15 373), 420 (2·7%) developed cutaneous melanoma (173 invasive, 247 in situ) during a median follow-up time of 4·4 years. Country of birth, age at migration, having > 50 sunburns in childhood or adolescence, and a history of keratinocyte cancer or actinic lesions were significantly associated with melanoma risk. CONCLUSIONS An interaction with polygenic risk was suggested: among people at low polygenic risk, markers of cumulative sun exposure (as measured by actinic damage) were associated with melanoma. In contrast, among people at high polygenic risk, markers of high-level early-life ambient exposure (as measured by place of birth) were associated with melanoma (hazard ratio for born in Australia vs. overseas 3·16, 95% confidence interval 1·39-7·22). These findings suggest interactions between genotype and environment that are consistent with divergent pathways for melanoma development. What's already known about this topic? The relationship between sun exposure and melanoma is complex, and exposure effects are highly modified by host factors and behaviours. The role of genotype on the relationship between ultraviolet radiation exposure and melanoma risk is poorly understood. What does this study add? We found that country of birth, age at migration, sunburns in childhood or adolescence, and history of keratinocyte cancer or actinic lesions were significantly associated with melanoma risk, while other measures of continuous or more intermittent patterns of sun exposure were not. We found evidence for gene-environment interactions that are consistent with divergent pathways for melanoma development. Linked Comment: Cust. Br J Dermatol 2020; 183:205-206.

Abstract
Malignant melanoma is the most aggressive and treatment resistant type of skin cancer. It is characterized by continuously rising incidence and high mortality rate due to its high metastatic potential. Various types of cell adhesion molecules have been implicated in tumor progression in melanoma. One of these, the carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1), is a multi-functional receptor protein potentially expressed in epithelia, endothelia, and leukocytes. CEACAM1 often appears in four isoforms differing in the length of their extracellular and intracellular domains. Both the CEACAM1 expression in general, and the ratio of the expressed CEACAM1 splice variants appear very dynamic. They depend on both the cell activation stage and the cell growth phase. Interestingly, normal melanocytes are negative for CEACAM1, while melanomas often show high expression. As a cell–cell communication molecule, CEACAM1 mediates the direct interaction between tumor and immune cells. In the tumor cell this interaction leads to functional inhibitions, and indirectly to decreased cancer cell immunogenicity by down-regulation of ligands of the NKG2D receptor. On natural killer (NK) cells it inhibits NKG2D-mediated cytolysis and signaling. This review focuses on novel mechanistic insights into CEACAM1 isoforms for NK cell-mediated immune escape mechanisms in melanoma, and their clinical relevance in patients suffering from malignant melanoma.

Abstract
BACKGROUND While ultraviolet (UV) radiation exposure is a recognized risk factor for skin cancer, associations are complex and few studies have allowed a direct comparison of exposure profiles associated with cutaneous melanoma, basal-cell carcinoma (BCC), and squamous-cell carcinoma (SCC) within a single population. METHODS We examined associations between UV exposures and skin cancer risk in a nested case-control study within E3N, a prospective cohort of 98,995 French women born in 1925-1950. In 2008, a lifetime UV exposure questionnaire was sent to all reported skin cancer cases and three controls per case, which were matched on age, county of birth, and education. Analyses were performed using conditional logistic regression and included 366 melanoma cases, 1,027 BCC cases, 165 SCC cases, and 3,647 controls. RESULTS A history of severe sunburns <25 years was associated with increased risks of all skin cancers (melanoma: OR 2.7; BCC: OR 1.7; SCC: OR 2.0 for ≥6 sunburns vs. none), while sunburns ≥25 years were associated with BCC and SCC only. While high-sun protection factor sunscreen use before age 25 was associated with lower BCC risk (Ptrend = 0.02), use since age 25 and reapplication of sunscreen were associated with higher risks of all three types of skin cancer. There were positive linear associations between total UV score and risks of BCC (Ptrend = 0.01) and SCC (Ptrend = 0.09), but not melanoma. While recreational UV score was strongly associated with BCC, total and residential UV scores were more strongly associated with SCC. CONCLUSIONS Melanoma, BCC, and SCC are associated with different sun exposure profiles in women.

Abstract
Background: Data show that intermittent painful sunburns are an important causative factor for cutaneous malignant melanoma. Objective: This study was undertaken to determine whether the differences in the anatomic distribution of melanomas in men, compared to women, could be accounted for by the distribution of sunburns and whether the high incidence of melanomas on the lower extremities of women is associated with the distribution of sunburns. Methods: One hundred and fifty nonmelanoma patients, men and women aged 20 to 60 years, recalled having painful sunburns within the previous 6 months. The locations of the sunburns were indicated on body surface diagrams. The locations of 1168 melanomas as recorded in the NYU-Melanoma Cooperative Group data base were plotted on anatomic diagrams. The anatomic distribution of melanomas and of sunburns for men and women were compared. Results: There was no statistically significant difference in the distribution of sunburns on any anatomic location in men as compared to women. However, there was a disproportionately high number of melanomas on the backs of men and on the legs of women. In both men and women, there was a significant difference between the anatomic distribution of painful sunburns and melanomas. Conclusion: Since the anatomic distribution of painful sunburns is similar in men and women, whereas the anatomic distribution of melanomas differ, it would appear that factors in addition to sunburns in adults account for the differences in the anatomic distribution of melanomas in men and women.

Abstract
Few studies have assessed the relationship between sunburn and risk of different skin cancers (melanoma, squamous cell carcinoma (SCC), and basal cell carcinoma (BCC)) in prospective studies simultaneously, and little is known about the association of severe sunburns at different body sites with skin cancer risk. We used data on 87,166 women in the Nurses' Health Study (1982-2010) and 32,959 men in the Health Professionals Follow-up Study (1992-2010) to investigate skin cancer risk associated with history of severe sunburns at different body sites (face/arms, trunk, and lower limbs). After adjustment for other risk factors, overall baseline history of severe sunburn was more apparently associated with risk of melanoma than with risk of SCC and BCC in men (multivariable-adjusted hazard ratios were 2.41 (95% confidence interval (CI): 1.32, 4.41) for melanoma, 1.48 (95% CI: 1.08, 2.03) for SCC, and 1.18 (95% CI: 1.06, 1.32) for BCC) but not in women. Sunburn on the trunk appeared to be more closely associated with melanoma risk, but not risk of SCC and BCC, when compared with sunburns at other body sites (face/arms and lower limbs). These differences were more apparent in men than in women. Pending further investigation, our findings add novel insights to the existing literature on sunburn history and skin cancer risk.

Abstract
BACKGROUND Invasive melanoma is becoming more common in U.S. Hispanics, yet little is known about the sun protection behaviors in this population, particularly children and adolescents who incur high ultraviolet (UV) exposures. METHODS We used latent class analysis to examine patterns of sun protective behaviors in a cross-sectional survey of Hispanic elementary students participating in a sun safety intervention in Los Angeles from 2013- to 2014 (N=972). Five behavior indicators in two environments (school and home) representing multiple methods of sun protection were selected for the model. RESULTS Results suggested a four-class model best fit the data. Classes were labeled in order of increasing risk as multiple protective behaviors (28%), clothing and shade (32%), pants only (15%), and low/inconsistent protective behaviors (25%). Children who reported high parental engagement with sun protection were significantly more likely to be classified in high overall protective categories (odds ratio (OR)=4.77). Girls were more likely than boys to be classified in the highest protecting class (OR=3.46), but were also more likely to be in the "pants only" class (OR=2.65). Sensitivity to sunburn was associated with less likelihood of being in the "clothing and shade" class (OR=0.53). CONCLUSION The differences among these classes and their predictors reveal the heterogeneity and complexity of Hispanic children's sun protective behaviors. These findings have implications for the design and delivery of future sun protection interventions targeting Hispanic children, as strategies tailored to specific subgroups may be more effective in achieving meaningful behavioral changes.

Abstract
Melanoma spreads through metastasis, and therefore, it has been proved to be very fatal. Statistical evidence has revealed that the majority of deaths resulting from skin cancer are as a result of melanoma. Further investigations have shown that the survival rates in patients depend on the stage of the cancer; early detection and intervention of melanoma implicate higher chances of cure. Clinical diagnosis and prognosis of melanoma are challenging, since the processes are prone to misdiagnosis and inaccuracies due to doctors’ subjectivity. Malignant melanomas are asymmetrical, have irregular borders, notched edges, and color variations, so analyzing the shape, color, and texture of the skin lesion is important for the early detection and prevention of melanoma. This paper proposes the two major components of a noninvasive real-time automated skin lesion analysis system for the early detection and prevention of melanoma. The first component is a real-time alert to help users prevent skinburn caused by sunlight; a novel equation to compute the time for skin to burn is thereby introduced. The second component is an automated image analysis module, which contains image acquisition, hair detection and exclusion, lesion segmentation, feature extraction, and classification. The proposed system uses PH2 Dermoscopy image database from Pedro Hispano Hospital for the development and testing purposes. The image database contains a total of 200 dermoscopy images of lesions, including benign, atypical, and melanoma cases. The experimental results show that the proposed system is efficient, achieving classification of the benign, atypical, and melanoma images with accuracy of 96.3%, 95.7%, and 97.5%, respectively.

Abstract
OBJECTIVE To assess the knowledge, attitudes and behaviour towards sun protection measures in a sample of Australian adults. METHODS A multicentre, cross-sectional study was undertaken during 2014 using a population-based survey of 416 individuals over the age of 18. The knowledge, behaviour and attitudes towards sun protection measures in this group of adults were assessed. The impact of educational level and employment status on responses was also evaluated. RESULTS Sunscreen is the most common sun-protective measure. Daily sunscreen use is below 20%. Forgetfulness was the largest barrier to sunscreen use. A total of 85% of respondents did not apply a sufficient amount of sunscreen. Only 32% of individuals reapplied sunscreen every 2 hours and 20% never reapplied it. In the preceding year, one or more sun burns were suffered by 46% of the participants in the survey. In all, 36% of individuals rarely or never check their sunscreens expiry date and less than 50% of individuals replaced their sunscreen each year. Furthermore, 65% were unaware that sunscreens stored above 25°C were less effective than when stored correctly as per manufactures labelling. CONCLUSIONS This study highlights a number of significant deficiencies that future sun-protection programmes could target in order to improve the general public's knowledge and attitudes towards sun protection. There is also a need for this to be translated into the public's sun-protection behaviour.

Abstract
BACKGROUND Public awareness campaigns could address risk factors for melanoma to reinforce their sun protection message. The objective of this study is to prioritise risk factors associated with malignant melanoma (MM) to improve public awareness. METHOD DESIGN A cross-sectional study with retrospective data analysis from 2004 to 2010. SETTING Western Australian Melanoma Advisory Service (WAMAS), a tertiary referral multidisciplinary organisation providing MM management advice. WAMAS data files were analysed with histologically confirmed cutaneous MM. Forty- seven patients had two or more melanomas, but the patient file was counted only once. Six MM data files with missing or incomplete information were excluded. MAIN OUTCOME MEASURES The number of naevi, blood relatives with MM, and previous sunburns were the primary variables collected. RESULTS The results showed that 70.9 per cent (268/378) had previous sunburn; 40.2 per cent (152/378) had multiple naevi; and 22.5 per cent (85/378) had a positive family history. In the 110 MM data files not associated with sunburn, multiple naevi and a positive family history represented 34.5 per cent (38/110) and 20.0 per cent (22/110), respectively. CONCLUSION The results confirm the findings of previous studies that multiple naevi and a positive family history are important risk factors associated with MM. We suggest that MM can be detected earlier and its mortality decreased by focusing on these high-risk groups who are not targeted by current public awareness campaigns.

Might outdoor heat stress be considered a proxy for the unperceivable effect of the ultraviolet-induced risk of erythema in Florence? JOURNAL OF PHOTOCHEMISTRY AND PHOTOBIOLOGY B-BIOLOGY 2014; 130:338-48.

Abstract
Erythema is the most familiar short-term symptom of human skin associated with overexposure to unperceivable ultraviolet radiation (UV). However, people are able to perceive the warm infrared component of the solar radiation by means of thermal (dis)comfort. This study investigated the potentiality of perceived outdoor heat stress as a valuable proxy for the unperceivable effect of UV-induced risk of erythema in a Mediterranean city. Meteorological data and UVB (280-320nm) measurements were obtained for the 2004-2012 period by a weather station located in the municipality of Florence. Continuous measurements of erythemally effective UV (UVEry) were performed by means of a broadband temperature-corrected radiometer with the spectral response close to the erythemal action spectrum. Hourly UVEry doses were expressed as Standard Erythemal Doses (SEDs). The newly developed Universal Thermal Climate Index (UTCI), that represents the state-of-the-art of outdoor thermal (dis)comfort evaluation, was also assessed. Descriptive analyses of the hourly distribution per month of the frequencies of days with heat stress and UVEry exceeding 2.0, 3.0, 4.5 and 6.0 SEDs were carried out based on the general skin-type characteristics. The association between UVEry and UTCI was analyzed by a two-way contingency table approach. The probability of UVEry exceeding specific SED thresholds when heat stress occurs was often significantly higher than the same probability when no heat stress is perceived. Furthermore, increased magnitudes of the ratios, ranging from the very sensitive to the minimally sensitive skin types, were also found. However, during several months, too many days occur without any signs of heat discomfort, even when people may be exposed to relevant doses of harmful UVEry for the skin of various phototypes. These findings underlie the need for public health authorities to provide differentiated advice per month in relation to potential UV skin damage in the city of Florence.

Abstract
BACKGROUND Sun exposure increases risk of skin cancer, especially melanoma, incidence of which continues to rise. Reported skin cancer knowledge and trends in sun care behaviours are documented in a UK region where there has been 20 years of sun-related health promotion campaigns. METHODS In 2000, 2004 and 2008, a 'care in the sun' module was included in the Northern Ireland (NI) Omnibus survey. Randomly selected subjects were asked to complete a sun-related questionnaire and proportions of respondents analysed by demographic and socio-economic factors, with differences tested using z-tests and the chi-squared test. RESULTS Around 3623 persons responded. Skin cancer knowledge was high (97%). Sun avoidance decreased with time and was lowest among younger age groups and males. Sunscreen use was high (70%), unchanged over 8 years, and more likely among younger age groups, females, those in paid employment, and those with tertiary level education. Use of sunscreen with minimum Sun Protection Factor (SPF) 15 (a campaign message) increased from 45% to 70% (P < 0.01). Skin self-examination was infrequent (8%), less common among those aged ≥65 years, males and those with only primary or secondary level education. CONCLUSIONS Messages on sunscreen use have penetrated the population well, but lower use among the unemployed suggests cost as an issue. Lack of sun avoidance in young people, especially men, poses a risk for further skin cancer increases. Low levels of reported skin self-examination in older people, men and those with lower educational attainment identify areas for further action.

Abstract
The skin is increasingly recognized as a component of the innate immune response, in addition to its role as a physical barrier. Although the deleterious effects of solar ultraviolet radiation (UVR), including immunosuppression and cutaneous tumorigenesis, are widely acknowledged, most studies to date have concentrated on adult skin. Despite the more sensitive nature of infant and toddler skin, little is known about its responses to UVR exposure, whether acute or long-term. Accumulating evidence suggests not only that the skin's barrier protection remains immature throughout at least the first 2 years of life but also that accumulation of UVR-induced changes in the skin may begin as early as the first summer of life. Such evidence not only affirms the importance of sun protection during the infant and toddler years but underscores the need for more research to establish evidence-based standards of care in this area. In this article we review recent studies in which differences between the skin properties of infants and young children and those of adults were compared, and we discuss the implications of these differences for sun-protection practices.

Abstract
The majority of tanning bed users in the U.S. are women. Previous health communication research frequently focused on the risk of skin cancer, but few studies assessed the mediated communication environment that may surround women's beliefs and behaviors relevant to tanning. A content analysis of articles in eight magazines targeting girls, young women, older women, and women who are interested in fitness during the ten-year period of 1997-2006 was conducted. The amount of coverage of tanning bed use consequences was less than 50% of the coverage of tanning benefits. About 40% of the tanning benefits coverage touted looking healthy. The coverage of prevention methods focused on sunscreen use (55%), while the more important methods (e.g., protective clothing use) were rarely featured. Longitudinally, the coverage of the risk and prevention relevant issues increased between 1997 and 2006. The data indicate that the coverage of tanning benefits also increased during the same period.

Abstract
OBJECTIVES Australia has the highest incidence of skin cancer in the world, despite prevention campaigns being implemented since the early 1980s. This study assesses the cost-effectiveness of a skin cancer prevention program (named SunSmart) since it was introduced, together with its potential cost-effectiveness as an upgraded and ongoing national program. METHODS The reduction in melanoma incidence attributable to SunSmart was modelled as the primary end-point. Historical expenditures on SunSmart were obtained from representative Australian states in three latitude zones. Melanoma incidence rates from these states were used to model key health outcomes. Non-melanoma skin cancer was modelled separately based on national survey results. RESULTS We estimate that SunSmart has averted 28,000 disability-adjusted life-years (DALYs), equivalent to 22,000 life-years saved, in the state of Victoria since its introduction in 1988, as well as saving money from cost offset in skin cancer management (dominant). An upgraded national program for the next 20 years is estimated to avert 120,000 DALYs, with associated reductions in the use of health care resources. It remains a dominant intervention in which every dollar invested in SunSmart will return an estimated AU$2.30. CONCLUSIONS This study demonstrates that a sustained modest investment in skin cancer control is likely to be an excellent value for money.

Abstract
Background Melanoma risk is related to sun exposure; we have investigated risk variation by tumour site and latitude. Methods We performed a pooled analysis of 15 case–control studies (5700 melanoma cases and 7216 controls), correlating patterns of sun exposure, sunburn and solar keratoses (three studies) with melanoma risk. Pooled odds ratios (pORs) and 95% Bayesian confidence intervals (CIs) were estimated using Bayesian unconditional polytomous logistic random-coefficients models. Results Recreational sun exposure was a risk factor for melanoma on the trunk (pOR = 1.7; 95% CI: 1.4–2.2) and limbs (pOR = 1.4; 95% CI: 1.1–1.7), but not head and neck (pOR = 1.1; 95% CI: 0.8–1.4), across latitudes. Occupational sun exposure was associated with risk of melanoma on the head and neck at low latitudes (pOR = 1.7; 95% CI: 1.0–3.0). Total sun exposure was associated with increased risk of melanoma on the limbs at low latitudes (pOR = 1.5; 95% CI: 1.0–2.2), but not at other body sites or other latitudes. The pORs for sunburn in childhood were 1.5 (95% CI: 1.3–1.7), 1.5 (95% CI: 1.3–1.7) and 1.4 (95% CI: 1.1–1.7) for melanoma on the trunk, limbs, and head and neck, respectively, showing little variation across latitudes. The presence of head and neck solar keratoses was associated with increased risk of melanoma on the head and neck (pOR = 4.0; 95% CI: 1.7–9.1) and limbs (pOR = 4.0; 95% CI: 1.9–8.4). Conclusion Melanoma risk at different body sites is associated with different amounts and patterns of sun exposure. Recreational sun exposure and sunburn are strong predictors of melanoma at all latitudes, whereas measures of occupational and total sun exposure appear to predict melanoma predominately at low latitudes.

Abstract
This article reviews the research on, and examines the epidemiology and prevention of melanoma. Despite the great quantity of research into environmental and genetic causes, and the ease of diagnosis, incidence and mortality have risen in all developed countries during the last half century. Patient and physician education, and public health programs aimed at prevention, have had varied success. The authors conclude that, until we have better data on how to prevent skin cancer of all types, the best solutions are education of high-risk populations about skin self-evaluation in combination with physician examination to practice; and sun protection.

Abstract
OBJECTIVE To report on the prevalence, clustering, and correlates of behavioral risk factors for cancer in the Queensland, Australia, population. DESIGN, SETTING, AND PARTICIPANTS The Queensland Cancer Risk Study was a population-based survey of 9419 Queensland residents aged 20-75 years. Information was collected through anonymous computer-assisted telephone interviews between February and November 2004. MAIN OUTCOME MEASURES Prevalence of tobacco smoking, alcohol consumption, obesity, physical inactivity, sun exposure, and inadequate fruit and vegetable intake, weighted by age, gender, and geographic region. RESULTS The majority of respondents reported between two and four cancer risk behaviors (79.4%). Men, those younger than 59 years and those with lower educational attainment had more than twofold increased odds of reporting multiple cancer risk factors. Marital status and geographic region were moderately associated with cancer risk. Smoking, high levels of alcohol consumption, and sun exposure were associated with up to twofold increased odds of engaging in multiple additional risk factors. CONCLUSIONS This study identified key subgroups of the Queensland population with increased odds of engaging in multiple risk behaviors for cancer, particularly younger men and people with lower educational attainment. Individual behavioral risk factors can also exert a significant impact on the overall risk profile, and this may be a useful consideration for public health campaigns that target key health behaviors.

Abstract
BACKGROUND Sunburn is a major preventable risk factor for skin cancer. OBJECTIVE We investigated risk factors for sunburn in the United States based on the 2003 Behavioral Risk Factor Surveillance System. DESIGN AND METHODS A random sample of 207,776 respondents provided data for the population-based survey. The main outcome measure was any report of sunburn within the previous 12 months. RESULTS Overall, 39% of respondents had at least one sunburn. The strongest factors associated with sunburn were age and socioeconomic factors. Sunburn prevalence was greatest in respondents 18 to 24 years old (61%). This group was more likely to have a sunburn than respondents 45 to 54 years of age (odds ratio [OR] = 2.76). Higher income and higher levels of education were positively associated with sunburn (OR 1.67 and 1.63, respectively). Individuals reporting recent binge drinking had a higher prevalence of sunburn (OR = 1.33). LIMITATIONS The Behavioral Risk Factor Surveillance System does not include data on skin type or sun protection behavior; therefore the impact of these factors was not assessed. CONCLUSION Sunburn occurs at a very high rate in the United States.

Abstract
Skin cancer has become the most common neoplasm in the United States. With early diagnosis and appropriate management, most skin cancers have an overall 5-year survival rate of 95%. Cutaneous malignant melanoma (CMM), however, has a significantly higher morbidity and mortality, resulting in 65% of all skin cancer deaths. Although the long-term survival rate for patients with metastatic melanoma is only 5%, early detection of CMM carries an excellent prognosis, with surgical excision often being curative. Primary care physicians can play a critical role in reducing morbidity and mortality from CMM by recognizing patients at risk, encouraging the adoption of risk-reducing behaviors, and becoming adept at identifying suspicious lesions.

Abstract
BACKGROUND Malignant melanoma is the third most common skin cancer in the United States. It is commonly thought that sun exposure is causative in these tumors. Recently, however, the significance of the role of sun exposure in melanoma has come into question. Some have suggested that other factors, such as genetics, play a larger role, and that sun protection may even be harmful. OBJECTIVE AND METHODS To investigate the role of sun exposure in melanoma etiology. An extensive review of basic science and clinical literature on this subject was conducted. RESULTS Although exceptions exist, sun exposure likely plays a large role in most melanomas. The pattern of this exposure, however, is not fully known, and controversy exists, especially in the use of sunscreens. Sun exposure may interact with genetic factors to cause melanomas, and sun protective measures appear to be prudent. CONCLUSIONS The cause of melanoma is probably variable and multifactorial. Sun exposure may play a primary or supporting role in most melanoma tumors.

Abstract
BACKGROUND As skin cancer education programmes directed to children and adolescents continue to expand, an epidemiological basis for these programmes is necessary to target efforts and plan for further evaluation. AIMS To summarise the epidemiological evidence on sun exposure during childhood and adolescence and melanoma risk. METHODS A literature review was conducted using Medline (1966 to December 2004) to identify articles relating to sun exposure and melanoma. The review was restricted to studies that included sun exposure information on subjects 18 years of age or younger. RESULTS Migrant studies generally indicate an increased melanoma risk in individuals who spent childhood in sunny geographical locations, and decreasing melanoma risk with older age at arrival. Individuals who resided in geographical locations close to the equator or close to the coast during childhood and/or adolescence have an increased melanoma risk compared to those who lived at higher latitudes or never lived near the coast. The intermittent exposure hypothesis remains controversial; some studies indicate that children and adolescents who received intermittent sun exposure during vacation, recreation, or occupation are at increased melanoma risk as adults, but more recent studies suggest intermittent exposure to have a protective effect. The majority of sunburn studies suggest a positive association between early age sunburn and subsequent risk of melanoma. CONCLUSION Future research efforts should focus on: (1) clarifying the relation between sun exposure and melanoma; (2) conducting prospective studies; (3) assessing sun exposure during different time periods of life using a reliable and quantitative method; (4) obtaining information on protective measures; and (5) examining the interrelations between ability to tan, propensity to burn, skin type, history of sunburns, timing and pattern of sun exposure, number of nevi, and other host factors in the child and adolescent populations.

Abstract
The incidence of skin cancer has risen rapidly in the UK over the last 20 years, prompting public health organizations to try and raise awareness of the dangers of sun exposure and the need to practice sun-safe behaviour. This study aimed to assess baseline levels of sun-safe knowledge and behaviour in a British population-representative sample, prior to the launch of Cancer Research UK's 'SunSmart' campaign. A face-to-face survey was conducted through the Office for National Statistics as part of their Omnibus survey. In total, 1848 men and women aged 18 and over were interviewed. Knowledge of what to do to reduce skin cancer risk was modest. Two-thirds mentioned avoiding the sun by seeking shade, 50% mentioned covering up and only 43% said to use high factor sunscreen. Practice of sun-safe behaviours was also poor, with only one-third saying they sought shade, covered up or used high factor sunscreen to protect themselves from the sun. Men and those from lower socioeconomic groups were least informed and least likely to report using sun-protective behaviours. Increases in both knowledge and use of appropriate sun-protective behaviours are needed if skin cancer incidence rates are to decrease.

Abstract
Purpose Incidence and mortality of cutaneous melanoma is rising rapidly in the United States; therefore, identifying risk factors for melanoma and integrating them into a clinical and population risk estimation tool may help guide prevention efforts and identify participants for preventive interventions. Methods We examined risk factors for melanoma in three large prospective studies of women and men. We observed 152,949 women and 25,206 men free of cancer at baseline for up to 14 years. Results A total of 535 incident cases of invasive melanoma (444 women and 91 men) were included in the analysis. We combined the three studies to examine risk factors and to build a risk model to calculate melanoma risk score. Older age, male sex, family history of melanoma, higher number of nevi, history of severe sunburn, and light hair color were each associated with significantly elevated risk of melanoma and were included in the final risk prediction. Participants at the highest decile of risk had a more than three-fold increase in risk of melanoma compared with those in the lowest decile (observed relative risk, 3.61; expected relative risk, 4.20). The measure of discriminatory accuracy as summarized by an age-and sex-adjusted concordance statistic of 0.62 (95% CI, 0.58 to 0.65) indicated that the model had reasonable ability to differentiate those who will develop melanoma and those who will remain free from the disease. Conclusion We identified several risk factors for melanoma and developed statistical models with adequate performance and discriminatory accuracy.

Abstract
A systematic revision of the literature was conducted in order to undertake a comprehensive meta-analysis of all published observational studies on melanoma. An extensive analysis of the inconsistencies and variability in the estimates was performed to provide some clues about its Epidemiology. Following a systematic literature search, relative risks (RRs) for sun exposure were extracted from 57 studies published before September 2002. Intermittent sun exposure and sunburn history were shown to play considerable roles as risk factors for melanoma, whereas a high occupational sun exposure seemed to be inversely associated to melanoma. The country of study and adjustment of the estimates adjuste for phenotype and photo-type were significantly associated with the variability of the intermittent sun exposure estimates (P = 0.024, 0.003 and 0.030, respectively). For chronic sun exposure, inclusion of controls with dermatological diseases and latitude resulted in significantly different data (P = 0.05 and 0.031, respectively). Latitude was also shown to be important (P = 0.031) for a history of sunburn; studies conducted at higher latitudes presented higher risks for a history of sunburns. Role of country, inclusion of controls with dermatological diseases and other study features seemed to suggest that "well conducted" studies supported the intermittent sun exposure hypothesis: a positive association for intermittent sun exposure and an inverse association with a high continuous pattern of sun exposure.

Abstract
Although benign and atypical moles are considered key melanoma risk factors, previous studies of their influence were small and/or institution-based. We conducted a population-based case-control study in the state of New Hampshire. Individuals of ages 20-69 with an incident diagnosis of first primary cutaneous melanoma were ascertained through the New Hampshire State Cancer Registry. Controls were identified through New Hampshire driver's license lists and frequency-matched by age and gender to cases. We interviewed 423 eligible cases and 678 eligible controls. Host characteristics, including mole counts, were evaluated using logistic regression analyses. Our results showed that pigmentary factors, including eye color (OR = 1.57 for blue eyes compared to brown), hair color (OR = 1.85 for blonde/red hair color compared to brown/black), freckles before age 15 (OR = 2.39 for freckles present compared to absent) and sun sensitivity (OR = 2.25 for peeling sunburn followed by no tan or a light tan and 2.42 for sunburn followed by tan compared to tanning immediately), were related to melanoma risk; these associations held after adjustment for sun-related factors and for moles. In analyses confined to skin examination participants, the covariate-adjusted effects of benign and atypical moles were moderately strong. Compared to 0-4 benign moles, risk increased steadily for 5-14 moles (OR = 1.71), 15-24 moles (OR = 3.55) and >or= 25 moles (OR = 4.33). Risk also increased with the number of atypical moles; compared to none, the ORs for having 1, 2-3, or >or= 4 atypical moles were 2.08, 1.84 and 3.80, respectively. Although risk was highest for those with multiple benign and atypical moles, the interaction was not of statistical significance. Our findings, arising from the first population- and incidence-based study to evaluate atypical moles in relation to melanoma risk, confirm the importance of host susceptibility, represented by pigmentary factors and the tendency to develop benign or atypical moles, in the etiology of this disease.

Abstract
The relationship between skin cancer and ultraviolet radiation is well established. Behaviors such as seeking shade, avoiding sun exposure during peak hours of radiation, wearing protective clothing, or some combination of these behaviors can provide protection. Sunscreen use alone is not considered an adequate protection against ultraviolet radiation. This report presents the results of systematic reviews of effectiveness, applicability, other harms or benefits, economic evaluations, and barriers to use of selected interventions to prevent skin cancer by reducing exposure to ultraviolet radiation. The Task Force on Community Preventive Services found that education and policy approaches to increasing sun-protective behaviors were effective when implemented in primary schools and in recreational or tourism settings, but found insufficient evidence to determine effectiveness when implemented in other settings, such as child care centers, secondary schools and colleges, and occupational settings. They also found insufficient evidence to determine the effectiveness of interventions oriented to healthcare settings and providers, media campaigns alone, interventions oriented to parents or caregivers of children, and community-wide multicomponent interventions. The report also provides suggestions for areas for future research.

Abstract
OBJECTIVE To describe pediatricians' attitudes toward skin cancer (SC), sun protection (SP) counseling, and the quantity and content of such counseling and to identify barriers to counseling. METHODS An American Academy of Pediatrics Periodic Survey was mailed to 1616 randomly selected US members between October 2001 and February 2002. The response rate was 54.6%. RESULTS More than 90% of pediatricians agreed that SC is a significant public health problem and that preventing episodic high exposures to the sun during childhood will reduce the risk of adult melanoma. However, only 22.3% of respondents reported counseling most patients in all age groups. Female pediatricians were more likely to counsel most patients; pediatricians located in the South and West and those who practice in hospital/clinic settings were least likely to counsel compared with those in other regions. Approximately half (53%) of pediatricians reported selectively counseling on the basis of patient characteristics The most important SP recommendation named was using a sunscreen with a sun protection factor > or =15. Only 38% of pediatricians rated SP as very important to their patients' health compared with other topics such as use of car seats (86%), nutrition (79%), immunization issues (76%), and smoking/avoidance of environmental tobacco smoke (74%). The most frequently named barrier to SP counseling was lack of time (58% reporting). CONCLUSIONS Although the majority of pediatricians believe that SC prevention is a worthy issue, only a minority reported providing routine SP counseling to most patients in every age group, and most ranked SP lower in importance than other issues. Interventions might include programs and materials to educate patients and pediatricians alike. To have an effect on increasing rates of SC and SC mortality, a broader public health approach is needed as a complement to pediatricians' counseling efforts.

Abstract
BACKGROUND Exposure to high levels of sunlight, such as a sunburn, is a strong determinant of melanoma risk. METHODS To describe statewide and U.S. estimates of sunburn prevalence in the United States and determine demographic and behavioral predictors of sunburn, we analyzed data from the 1999 Behavioral Risk Factor Surveillance System, a population-based telephone survey conducted in all 50 states, the District of Columbia, and Puerto Rico. RESULTS Of 156,354 adults aged > or =18 years, 31.7% (95% confidence interval, 31.3%-32.1%) reported a sunburn in the past year; of adults aged 18 to 29 years, 57.5% reported such a sunburn. Reporting was highest among white, non-Hispanic males (44.1%), followed by white non-Hispanic females (35.3%), and lowest among black non-Hispanic males and females (5.1% and 5.3%, respectively). Statewide period prevalence of sunburn among whites was highest (>45%) in Wisconsin, Utah, Wyoming, Washington, DC, and Indiana, and lowest (<30%) in Puerto Rico, Arizona, Tennessee, Oklahoma, and New York. CONCLUSIONS Nationwide and statewide skin cancer prevention efforts should target young adults. Periodic monitoring of sunburn is important in evaluating the effectiveness of those efforts.

Abstract
BACKGROUND A preventive effect of sunscreens on melanoma development is still subject of intense discussion. The practical consequences for changes in public health campaigns are neglected in this debate. METHODS An extensive literature search for studies on the association between sunscreen use and melanoma occurrence was performed. The principles of evidence-based medicine (EBM) are applied to the issue to derive at recommendations for an evidence-based prevention of melanoma. RESULTS We identified 17 case-control studies providing risk estimates for the relationship under study. These risk estimates are too heterogeneous to allow a reasonable conclusion by summarizing the evidence. The application of the EBM approach yields therefore an inconclusive result: the melanoma protective potential of sunscreens cannot be proven using the existing evidence. The information necessary to fully assess the effect of sunscreen use on melanoma development is not currently available. CONCLUSION Based on the current evidence the focus of recommendations for melanoma prevention in public awareness campaigns has to be changed. It should be much more emphasized to minimize exposure to ultraviolet (UV) radiation during peak hours, wear protective clothing, hats and UV-opaque sunglasses, seek shade and protect infants and children against too much UV radiation exposure at all than to use sunscreens.

Abstract
Most European children experience exposure to the sun during the summer holidays. The aim of this study was to examine the behaviour of European children when in the sun during their holidays. In 1995-1997, a total of 631 young children were recruited during a multicentric study in Belgium, Germany, France and Italy. For each holiday period from birth, parents gave detailed information on sun exposure and child behaviour. Predictors and trends over time of sun protection were investigated. Forty percent of children were exposed to sunlight in the first and 86% in the sixth year of life. At the same time, the number of children who experienced sunburns rose from 1 to 23%. In the whole period of 6 years, only 8% of children always wore trousers and shirt when in the sun, while 25% children always used a sunscreen. The proportion of sun-exposed children who used sunscreen was stable with age (approximately 50%), while those who always wore trousers and shirts dropped from 46% (1st year) to 19% (6th year). Multinomial logistic regression showed that sunscreen use, but not the wearing of clothes was associated with sun-sensitivity. In summary, sun exposure increases steadily, while sun protection decreases in the first 6 years of life in our cohort of children. In this cohort, use of a sunscreen was much more frequent than the wearing of clothes and a reduction in sun exposure.
