Abstract
BACKGROUND Skin cancer survivors are more vulnerable to subsequent skin cancers and other malignancies, but previous studies have not examined in detail their sun protection behavior prevalence by sociodemographic factors. We aimed to understand the sociodemographic disparities in the prevalence of three important types of sun protection behaviors: using sunscreen, seeking shade, and wearing protective clothing, among skin cancer survivors and those without skin cancer history. METHODS We used the 2015 U.S. National Health Interview Survey to analyze 29,523 participants, of which 772 were skin cancer survivors and 28,751 were those without skin cancer history. We assessed overall and specific sun protection behavior prevalence based on using sunscreen, seeking shade, and wearing protective clothing. Weighted Poisson regression was used to estimate prevalence ratios. RESULTS Melanoma and nonmelanoma skin cancer survivors had similar overall sun protection behavior (p > .05). Among all skin cancer survivors, 36.0% infrequently used sunscreen, 50.2% infrequently wore protective clothing, 47.8% infrequently sought shade, and 30.0% lacked frequent overall sun protection, which significantly differed from those without skin cancer history (p < .0001). The prevalence of frequent overall sun protection behavior was lower for those who were younger at survey, males, less educated, single or never married, or lived in poverty, regardless of their skin cancer history (p < .01). CONCLUSIONS By identifying subpopulations with higher prevalence of infrequent sun protection among those with or without skin cancer history, our findings may encourage efforts to reduce sociodemographic disparities in sun protection behaviors and promote primary and tertiary skin cancer prevention.

Abstract
The major cause for skin cancer is the excessive and unprotected exposure to ultraviolet radiation (UVR), which can be prevented by engaging in sun protection behaviours. As longitudinal studies on both adolescents' and adults' performances of sun protection behaviours are limited, the current study aimed to investigate changes in sun protection in these population segments in Western Australia, a region with high annual UVR. During six summer seasons (2015/16 to 2020/21), cross-sectional surveys were conducted among 1806 adolescents (14 to 17 years old) and 1808 adults (18-45 years old), investigating the frequency of five sun protection behaviours (wearing clothing, applying sunscreen, wearing a hat, wearing sunglasses, and seeking shade) and sun avoidance (staying indoors). Over the six-year period, staying indoors increased in both groups. Among adolescents, a decrease in wearing clothing and sunglasses and an increase in seeking shade was demonstrated, and hat and sunscreen use remained relatively stable. Among adults, an increase in sunscreen use was shown, whereas all other sun-related behaviours remained consistent over the six-year period. The results from this study can provide directions for health communications focusing on improving sun protection behaviours among both adolescent and adult populations.

The Effects of Using the Sun Safe App on Sun Health Knowledge and Behaviors of Young Teenagers: Results of Pilot Intervention Studies. JMIR DERMATOLOGY 2022; 5:e35137. [PMID: 37632872 PMCID: PMC10334904 DOI: 10.2196/35137] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 01/31/2022] [Accepted: 02/02/2022] [Indexed: 01/05/2023] Open
Abstract
BACKGROUND A balanced approach toward sun exposure and protection is needed by young people. Excessive sun exposure increases their risk for skin cancers such as melanoma, whereas some exposure is necessary for vitamin D and healthy bones. We have developed a new iOS smartphone app-Sun Safe-through a co-design process, which aims to support healthy and balanced decision-making by young teenagers (aged 12-13 years). OBJECTIVE The aim of this study was to test the capacity of Sun Safe to improve sun health knowledge and behaviors of young teenagers in 3 pilot intervention studies completed in 2020. METHODS Young teenagers (aged 12-13 years; N=57) were recruited through the web or through a local school via an open-access website and given access to Sun Safe (29/57, 51%) or a placebo (SunDial) app (28/57, 49%). Participants completed sun health questionnaires and knowledge quizzes before and after the 6-week intervention (either on the web or in class) and rated the quality of the app they used via a survey. RESULTS Of the 57 participants, 51 (89%) participants (26, 51% for placebo arm and 25, 49% for the Sun Safe arm) completed these studies, with most (>50%) reporting that they used a smartphone to access their designated app either "once a fortnight" or "once/twice in total." Improved sun health knowledge-particularly about the UV Index-was observed in participants who were given access to Sun Safe compared with those who used the placebo (-6.2 [percentage correct] difference in predicted means, 95% CI -12.4 to -0.03; P=.049; 2-way ANOVA). Unexpectedly, there were significantly more sunburn events in the Sun Safe group (relative risk 1.7, 95% CI 1.1-1.8; P=.02; Fisher exact test), although no differences in time spent outdoors or sun-protective behaviors were reported. COVID-19 pandemic-related community-wide shutdowns during April 2020 (when schools were closed) reduced the time spent outdoors by >100 minutes per day (-105 minutes per day difference in predicted means, 95% CI -150 to -59 minutes per day; P=.002; paired 2-tailed Student t test). Sun Safe was well-rated by participants, particularly for information (mean 4.2, SD 0.6 out of 5). CONCLUSIONS Access to the Sun Safe app increased sun health knowledge among young teenagers in these pilot intervention studies. Further investigations with larger sample sizes are required to confirm these observations and further test the effects of Sun Safe on sun-protective behaviors.

Abstract
There is growing evidence suggesting that text-message-based interventions are effective to promote sun protection behaviors. However, it is still unclear how engagement and adherence with the intervention messages can be optimized through intervention design. This study evaluated the effect of different combinations of personalized and two-way interactive messages on participant engagement with a theory-based skin cancer prevention intervention. In the SunText study conducted in February-July 2019 in Queensland, Australia participants 18-40 years were randomized to four different text message schedules using a Latin square design. This study analyzed if the order and intensity in which the schedules were received were associated with participants' level of engagement, and if this differed by demographic factors. Out of the 389 participants enrolled in the study, 375 completed the intervention period and remained for analysis. The overall intervention engagement rate was 71% and decreased from the beginning to the end of the study (82.2%-61.4%). The group starting with personalized, but not interactive messaging showed the lowest engagement rate. The intervention involving interactive messages three times a week for 4 weeks achieved the highest engagement rate. The intervention with increasing frequency (personalized and interactive three times a week for 2 weeks; then daily for 2 weeks) had lower engagement than intervention with constant or decreasing frequency. Engagement with two-way interactive messages was high across all intervention groups. Results suggest enhanced engagement with constant or decreasing message frequency compared to increasing frequency.

Developing an Online Tool to Promote Safe Sun Behaviors With Young Teenagers as Co-researchers. Front Digit Health 2021; 3:626606. [PMID: 34713099 PMCID: PMC8521794 DOI: 10.3389/fdgth.2021.626606] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Accepted: 02/08/2021] [Indexed: 11/13/2022] Open
Abstract
Despite education about the risks of excessive sun exposure, teenagers in Australia are sun-seeking, with sunburn common in summer. Conversely, some regular (time-limited) exposure to sunlight (that avoids sunburn) is necessary for vitamin D and healthy bones and other molecules important for immune and metabolic health. New interventions are thus required to better support teenagers to make healthy and balanced decisions about their sun behaviors. This paper describes the development of a prototype online tool—a smartphone app—that aimed to foster safe sun practices in teenagers. We recruited young adolescents (aged 12–13 years, n = 24) as “co-researchers” to provide ongoing input into the nature and design of the online tool. This age group was selected, as it is a critical time when young people transition from primary education, where “SunSmart” behaviors are entrenched in Australian schools, to high school, where risky behaviors emerge. Through a series of interviews and workshops, we codesigned an Apple iOS smartphone app with the co-researchers, leading health promotion professionals, researchers, and app designers. The developed app, Sun Safe, contains educational content relevant to teenagers about safe sun behaviors, complemented by other features requested by co-researchers and stakeholders to help engage young people, including gamified quizzes to test their sun health knowledge, real-time weather data on the UV Index and temperature, a sunscreen application timer, and reminders to check the UV Index. The developed prototype app was rated well by co-researchers, suggesting it is suitable for further feasibility and efficacy testing as an intervention tool to improve knowledge and promote safe sun behaviors by young adolescents.

Abstract
OBJECTIVE This study aimed to explore current attitudes towards sun protection, and sun-seeking behaviour among young Australian adolescents. It was done as part of a larger project aiming to develop a digital resource to support young people in making informed sun-health decisions. RESULTS Ten (4 male, 6 female) adolescents (12-13 years of age) living in Perth (Western Australia) were recruited through a social media-based strategy. Each participant engaged in a semi-structured telephone interview which explored their sun-health decision-making, with interview transcripts assessed qualitatively using NVivo. Three major themes (and eight sub-themes) were identified: (1) 'personal sun health considerations'; (2) 'attitudes towards sun protection'; and (3) 'recommendations'. The importance of sun protection was appreciated by participants. However, females were more diligent in the use of sun protection while males were indifferent. Behaviours were influenced by parental input, the school environment and engagement in sport. Adolescents had limited knowledge of the UV Index and its implications for sun protection, and the health importance of sun-derived vitamin D. Overall, the importance of sun protection was acknowledged but did not consistently translate into sun protective behaviours.

A Randomized Trial of Precision Prevention Materials to Improve Primary and Secondary Melanoma Prevention Activities among Individuals with Limited Melanoma Risk Phenotypes. Cancers (Basel) 2021; 13:cancers13133143.

Abstract
Simple Summary Inherited genetic variation at the MC1R gene is associated with increased risk of melanoma among non-Hispanic whites (NHWs), especially among those with skin and pigmentation characteristics that are associated with average to lower melanoma risk, for whom MC1R genetic testing may reveal unrecognized melanoma risk. We conducted a randomized trial to examine whether providing MC1R genetic risk information together with precision prevention materials would increase primary and secondary melanoma preventive behaviors compared to providing generic prevention materials only. We found that among participants with MC1R variants associated with higher risk of melanoma, the intervention increased shade-seeking or using an umbrella, increased wearing sleeved shirts, and decreased sunburns among their young children. We conclude that MC1R genetic testing and precision prevention materials may increase the practice of some sun-protective behaviors. Abstract Inherited variation at MC1R is associated with elevated melanoma risk among non-Hispanic whites (NHWs). MC1R genetic testing may unmask previously unrecognized disease risk, especially among individuals with few melanoma phenotypic risk factors. We recruited NHW individuals with limited phenotypic risk factors from two primary care clinics in west-central Florida. Participants (n = 1134) were randomized within MC1R genotype risk group (average/higher) to receive mailed precision prevention (i.e., intervention) or generic prevention materials. Participants reported hours of weekday and weekend sun exposure, frequency of intentional outdoor tanning and sun protection behaviors, number of sunburns, indoor tanning episodes, and skin examinations at baseline, and after 6 and 12 months. Among MC1R higher-risk participants, the intervention increased the likelihood of often or always wearing a shirt with sleeves (OR = 1.49, p = 0.03) and seeking shade or using an umbrella (OR = 1.42, p = 0.046), and it decreased the number of sunburns among their young children (β = −0.13, p = 0.03). Intervention effects were not noted among MC1R average-risk participants. Moderation analyses identified intervention effects within subgroups in average-risk and higher-risk participants. Precision prevention information conveying MC1R testing results can increase the practice of some sun protection behaviors among at-risk individuals with limited melanoma risk phenotypes and may provide a cross-generational tool to counteract increasing incidence of melanoma.

Abstract
OBJECTIVE To inform skin cancer prevention policies and campaigns, we investigated changes over time in sun protection behaviours, sunburn, sun exposure and shade availability in public spaces among people living in New South Wales (NSW), Australia, between 2003 and 2016. METHODS We analysed cross-sectional data from the NSW Population Health Survey collected in 2003, 2007, 2014 and 2016, which included approximately 15,000 respondents of all ages in each year. Logistic regression models were used to analyse overall changes over time and for different age, sex and sociodemographic groups. RESULTS The use of sunscreen and protective clothing and the availability of shade increased between 2003 and 2016, but sunburn and sun exposure during peak times of ultraviolet radiation also increased. In subgroup analyses, there was no improvement in sun protection behaviours among adolescents and increases in sunburn and sun exposure were observed only among adults, particularly women and in areas with less social disadvantage. CONCLUSIONS Sun protection behaviours have improved over time among some population subgroups, but over-exposure to ultraviolet radiation remains prevalent. Implications for public health: Skin cancer prevention initiatives that specifically target adolescents and sun exposure during peak times are needed to help reduce population skin cancer risk.

Abstract
BACKGROUND Individuals from melanoma-prone families have similar or reduced sun-protective behaviors compared to the general population. Studies on trends in sun-related behaviors have been temporally and geographically limited. METHODS Individuals from an international consortium of melanoma-prone families (GenoMEL) were retrospectively asked about sunscreen use, sun exposure (time spent outside), sunburns, and sunbed use at several timepoints over their lifetime. Generalized linear mixed models were used to examine the association between these outcomes and birth cohort defined by decade spans, after adjusting for covariates. RESULTS A total of 2407 participants from 547 families across 17 centers were analyzed. Sunscreen use increased across subsequent birth cohorts, and although the likelihood of sunburns increased until the 1950s birth cohort, it decreased thereafter. Average sun exposure did not change across the birth cohorts, and the likelihood of sunbed use increased in more recent birth cohorts. We generally did not find any differences in sun-related behavior when comparing melanoma cases to non-cases. Melanoma cases had increased sunscreen use, decreased sun exposure, and decreased odds of sunburn and sunbed use after melanoma diagnosis compared to before diagnosis. CONCLUSIONS Although sunscreen use has increased and the likelihood of sunburns has decreased in more recent birth cohorts, individuals in melanoma-prone families have not reduced their overall sun exposure and had an increased likelihood of sunbed use in more recent birth cohorts. These observations demonstrate partial improvements in melanoma prevention and suggest that additional intervention strategies may be needed to achieve optimal sun-protective behavior in melanoma-prone families.

Abstract
College and university students are a group known for excessive sun exposure and indoor tanning. Health education campaigns for avoidance of ultraviolet (UV) radiation have been relatively unsuccessful in this population. This systematic review examines interventions aimed at post-secondary school young adults on college and university campuses for skin cancer awareness, photoprotection, and change in UV-exposure-related behavior. Fifty-nine studies were identified for inclusion according to predetermined criteria. Study heterogeneity was high; methods of intervention were individual or group-based, and were mostly visually delivered and/or passive learning. Most interventions occurred at a single time point. Intervention success was assessed by evaluating subject behavior, intention, attitudes, knowledge, and emotion. Multicomponent interventions, generally consisting of UV photography and a passively delivered educational component, may be more effective than a single component alone. Overall, study quality was poor. Sample size of the majority of studies was <150 subjects. Most studies used self-report of behavior and had a short follow-up time. Generalizability of findings may be impacted as women, particularly white/Caucasian women, were overrepresented in the studies identified by this systematic review. For this specific target population, themes arising from the review include the importance of self-relevance and message framing. Self-affirmation was identified as a potential challenge in designing interventions for this target group, which can lead to defensiveness and a negative reaction to the health message. The findings of this systematic review may inform future research in this field, as well as guide planning of effective interventions in this target population.

Sun-protective clothing and shade use in public outdoor leisure settings from 1992 to 2019: Results from cross-sectional observational surveys in Melbourne, Australia. Prev Med 2020; 139:106230. [PMID: 32768510 DOI: 10.1016/j.ypmed.2020.106230] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2020] [Revised: 06/11/2020] [Accepted: 08/02/2020] [Indexed: 10/23/2022]
Abstract
Skin cancer presents a significant public health burden in Australia. The present study aimed to supplement population-based estimates of sun protection behaviour by examining setting-specific trends in directly observed sun protection in public outdoor leisure settings. Repeated cross-sectional observational surveys of adolescents and adults were conducted on summer weekends between 11 am and 3 pm from 1992 to 2002, 2006 to 2012, and 2018 to 2019 (N = 44,979) at pools/beaches and parks/gardens within 25 km of the centre of Melbourne, Victoria. The primary outcome was a binary index representing individuals having above or below the median level of body surface covered by hat, shirt, and leg garments in each setting type. The prevalence of above-median body coverage increased between 1992 and 2002 in both settings. At pools/beaches, a slight decline in above-median body coverage between 2006 and 2019 in males and females (adjusted odds ratio, AOR = 0.96 [0.94, 0.97]; 0.94 [0.93, 0.95]) appeared to be driven by a decline in leg coverage, while arm coverage, hat, sunglasses, and shade use remained stable. At parks/gardens, a decline in above-median body coverage between 2006 and 2019 (AOR = 0.90 [0.89, 0.91]; 0.94 [0.93, 0.95]) was accompanied by small declines across other protective behaviours that varied between males and females. Patterns in protective behaviours observed in outdoor leisure settings may reflect the changing composition of individuals choosing to remain outdoors during peak UV times and highlight the importance of continued promotion and monitoring of the use of multiple measures to protect against UV damage in Australia.

Attitudes about and practices for skin cancer prevention among patients with dermatological issues in Hanoi, Vietnam: a cross-sectional study. Environ Health Prev Med 2020; 25:35. [PMID: 32738889 PMCID: PMC7395371 DOI: 10.1186/s12199-020-00875-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2020] [Accepted: 07/22/2020] [Indexed: 12/09/2022] Open
Abstract
Background Raising awareness and educating people regarding practices for skin cancer or melanoma prevention are critical in the context of the adversely increasing effects of global climate change. This study aimed to explore the knowledge, attitudes, and practices regarding skin cancer prevention and to determine the associated factors to knowledge, attitudes, and practices among dermatological patients in Vietnam. Methods This cross-sectional study included 590 dermatological patients between 18 and 82 years of age, who received an examination or treatment from the National Hospital of Dermatology in Hanoi, Vietnam, from September to December 2018. The respondents’ attitudes on skin cancer and cancer prevention were assessed via face-to-face interviews with a structured questionnaire conducted by trained interviewers. Results Of the 590 respondents, the majority of people had correct responses to the question regarding skin cancer knowledge. Among the total participants, 39.8% thought that they were at risk of skin cancer, and 13.8% believed their occupation increased their skin cancer risk. The majority of respondents used hats (94.9%) and sunscreen skin coats (89.5%) and went into the shade (86.3%) when exposed to the sun. Women were less likely to be aware of their skin cancer risk but were more likely to practice prevention behaviors. Conclusion Our results show that dermatological patients have acceptable knowledge towards skin cancer prevention, but still need to change their behavior to prevent the risk of skin cancer. This study highlights the importance of education to raise awareness regarding skin cancer in order to promote practice prevention strategies for skin cancer in Vietnam.

Abstract
INTRODUCTION The use of sunscreen is an important preventive measure against skin cancer and treatment for other skin conditions. There is evidence pointing to lack awareness and misconceptions regarding use of Sunscreen. This is especially evident in populations with skin of color (POC). METHODS This is a cross-sectional study of 2000 individuals. A structured questionnaire was designed to collect data on general knowledge and use of sunscreen as well as reasons for stopping use of sunscreen. RESULTS The results of this study indicate a clear deficiency in the use and knowledge about sunscreen among Jordanians. Females are using sunscreen more than males. However, the use of sunscreen is inadequate in many aspects including timing of application, frequency of use, and amount used among other things. There is an obvious lack of knowledge about sunscreen as shown by lack of awareness about benefits of use in various times of the year, use in children, use for all skin types, and several misconceptions among other knowledge gaps. Main reasons for stopping sunscreen include side effects, cost, and being not suitable for skin. Awareness about sunscreen can be improved by proper counseling by healthcare professionals and utilization of various media platforms. CONCLUSIONS The use of sunscreen is inadequate in this population of color (POC). Lack of proper counseling, failure to read use instructions can contibute to inadequate use of sunscreen. Risks and benefits of sunscreen should be explained by medical professionals. The media should be more utilized to disseminate such knowledge.

Abstract
BACKGROUND The relationship between social media usage and the public's expressions of sunburn remains unexplored. This study is a content analysis of Twitter that was performed to identify the public's expressions, perceptions, and attitudes towards sunburn. METHODS Qualitative content analysis was conducted on tweets by Australian Twitter users during January 2007 and January 2016. Out of 2,000 tweets available, in-depth content analysis of 200 random tweets was performed. RESULTS Tweets in this study were categorised into 10 distinct themes, three of which were cognitive (fact based) and seven affective (emotional), while one was miscellaneous. Results reveal that tweets about sunburn overwhelmingly contained affective as opposed to cognitive components. In addition, the sentiments contained in the affective tweets were frequently positively (68.9%) rather than negatively valanced (31.1%). While humour was the most common theme (n = 68 tweets), many tweets also expressed a link between Australian national identity and sunburn (n = 25 tweets). CONCLUSION Many of the tweets analysed contained positive affective sentiments such as joy, rather than worry or concern, suggesting an avenue for further health promotion research.

Abstract
BACKGROUND Skin cancer places a substantial burden on the health system in Australia. The modernisation of skin cancer prevention interventions by using social media may enhance their contemporary reach and relevance, especially among the youth. This study aimed to analyse Twitter posts in Australia to establish a baseline of skin cancer and sun-related communication trends. METHODS Tweets posted over the summer of 2018/2019 relating to relevant keywords and hashtags such as "slipslopslap" and "sunscreen" were analysed using quantitative and qualitative methods. The number of tweets, related communication patterns, and possible factors for sudden changes in tweet volume were studied. RESULTS Results showed that Australians are using Twitter to communicate about their sun-related and skin cancer experiences and to share advice and information on this matter. Overall, Australians use Twitter more frequently to talk about sunscreen (number of tweets between December 2018 and February 2019 = 5,842) and/or skin cancer (n = 3,936), but not so often to communicate about other sun-protective behaviours (n = 1,972) or skin cancer prevention campaigns (n = 108). The number of tweets is greatly affected by the increase in temperature. Celebrities, non-health-related organisations with a high number of followers, and individuals sharing their own skin cancer experiences achieve a substantial number of likes and retweets and thus influence on Twitter regarding skin cancer-related communication. CONCLUSIONS The results allow deeper understanding of important determinants for effective social media use for health promotion and public health messaging in the future. Linking tweets with temperature, sharing by celebrities or non-health-related organisations and individuals with a high following can all contribute to greater spread of skin cancer and sun-related messages.

Abstract
The aim of this pilot study was to assess whether the installation of ultraviolet radiation (UVR) meters in secondary schools has the potential to improve adolescents’ sun protection-related knowledge, attitudes, and behaviours and reduce their exposure to UVR during school hours. Data were collected from students at two schools via online pre- and post-intervention surveys, measurement of sunscreen usage, polysulfone UVR exposure badges, and photographs of the schoolyards to assess hat and shade use. Several operational issues limited the quantity and quality of data that could be collected, and findings were mixed. While there were no significant changes in either self-reported or observed sun protection behaviours, there were significant improvements in UVR knowledge among students at the intervention school, and reactions to the meter were highly favourable. Students reported consulting the meter regularly and using it to make decisions about their sun protection behaviours. Overall, the study results offer some support for the use of UVR meters in areas frequented by adolescents and provide insights into the process issues that are likely to need to be addressed when attempting to trial sun protection interventions in schools.

Abstract
Myopia is an increasingly common condition that is associated with significant costs to individuals and society. Moreover, myopia is associated with increased risk of glaucoma, retinal detachment and myopic maculopathy, which in turn can lead to blindness. It is now well established that spending more time outdoors during childhood lowers the risk of developing myopia and may delay progression of myopia. There has been great interest in further exploring this relationship and exploiting it as a public health intervention aimed at preventing myopia in children. However, spending more time outdoors can have detrimental effects, such as increased risk of melanoma, cataract and pterygium. Understanding how spending more time outdoors prevents myopia could advance development of more targeted interventions for myopia. We reviewed the evidence for and against eight facets of spending time outdoors that may protect against myopia: brighter light, reduced peripheral defocus, higher vitamin D levels, differing chromatic spectrum of light, higher physical activity, entrained circadian rhythms, less near work and greater high spatial frequency (SF) energies. There is solid evidence that exposure to brighter light can reduce risk of myopia. Peripheral defocus is able to regulate eye growth but whether spending time outdoors substantially changes peripheral defocus patterns and how this could affect myopia risk is unclear. Spectrum of light, circadian rhythms and SF characteristics are plausible factors, but there is a lack of solid evidence from human studies. Vitamin D, physical activity and near work appear unlikely to mediate the relationship between time spent outdoors and myopia.

Abstract
ISSUE ADDRESSED This study explores the experiences of adults aged 18 years and older who received an unintended sunburn while wearing sunscreen and examines why the application of sunscreen as a sun protection measure did not work as intended. METHODS Qualitative content analysis was conducted on 11 interviews with people living in Australia who had received an unintended sunburn. Data were collected from July 2017 to January 2018. Twelve participants took part in individual semi-structured interviews either face-to-face or over the telephone, and 11 participants met the eligibility criteria and were included for analysis. RESULTS The themes that emerged included experience of disbelief after sunburn; sunburn after water-based activity; inaccurate sunscreen application; sunscreen acceptability and trust; discomfort in application, opportunistic sun exposure; aesthetically motivated behaviour; normative beliefs; and lack of awareness of recent sun safety campaigns. CONCLUSION Participants perceived themselves as well protected from sun exposure and were surprised they received a sunburn. We found that participants did not reapply sunscreen often enough, especially before and during water activities and overestimated the amount of time they could be safely exposed to the sun. SO WHAT?: The findings of this study suggest a greater need for sun protection education on how to effectively use and apply sunscreen to avoid sunburn and skin cancer. SUMMARY This study explores the experiences of adults aged 18 years and older who received an unintended sunburn while wearing sunscreen and examines why the application of sunscreen as a sun protection measure did not work as intended. Qualitative content analysis was conducted on 11 interviews with people living in Australia who had received an unintended sunburn.

Abstract
Importance There are limited data among young adults on sunscreen use during childhood and adulthood and on the association of sunscreen use with melanoma risk. Objective To assess correlates of early-life sunscreen use and the association between sunscreen use and risk of cutaneous melanoma before age 40 years. Design, Setting, and Participants This population-based, case-control family study analyzed Australian Melanoma Family Study data for persons with questionnaire data on sunscreen use collected by interview from 2001 to 2005 across 3 states in Australia, representing two-thirds of the country's population. Case participants (aged 18-39 years) had confirmed first primary melanoma. Siblings of case participants were included, and case participants without a sibling control were excluded. Unrelated controls (aged 18-44 years) were recruited from the electoral roll or were a spouse, partner, or friend nominated by case participants. Data analyses were conducted from October 2017 to February 2018. Exposures Self- and parent-reported sunscreen use, sun exposure, and other candidate risk factors during childhood and adulthood. Main Outcomes and Measures Logistic regression analyses adjusted for potential confounders were used to estimate odds ratios (ORs) for melanoma and for correlates of sunscreen use. Results Participation was 629 of 830 contactable cases (76%) (629 of 1197 overall [53%]), 240 of 570 contactable controls (42%) from the electoral roll (240 of 1068 overall [23%]), and 295 of 371 nominated spouse or friend controls (80%); analysis incuded 603 cases and 1088 controls. The median (interquartile range) age was 32 (28-36) years for 603 cases, 35 (30-38) years for 478 unrelated controls, and 34 (29-38) years for 610 sibling controls. There were more women than men (range, 57%-62%) in all groups, approximately 40% (range, 39%-43%) of participants had a university education, and most participants (range, 58%-73%) had British/northern European ethnicity. Risk of melanoma was less with higher use of sunscreen in childhood (OR for highest vs lowest tertiles, 0.60; 95% CI, 0.42-0.87; P = .02 for trend) and across the lifetime (OR, 0.65; 95% CI, 0.45-0.93; P = .07 for trend). Subgroup analyses suggested that the protective association of sunscreen with melanoma was stronger for people reporting blistering sunburn, receiving a diagnosis of melanoma at a younger age, or having some or many nevi. Total lifetime sun exposure was unrelated to melanoma risk (OR for highest vs lowest tertile, 0.97; 95% CI, 0.66-1.43; P = .94 for trend). By contrast, total sun exposure inversely weighted by sunscreen use (as a measure of sun exposure unprotected by sunscreen) was significantly associated with melanoma risk (OR, 1.80; 95% CI, 1.22-2.65; P = .007 for trend) and appeared stronger for people having lighter pigmentation or some or many nevi or using sunscreen to stay longer in the sun. Regular users of sunscreen were more likely to be female, younger, and of British or northern European ancestry and to have higher educational levels, lighter skin pigmentation, and a stronger history of blistering sunburn. Conclusions and Relevance Our findings provided evidence that regular sunscreen use is significantly associated with reduced risk of cutaneous melanoma among young adults and identified several characteristics associated with less sunscreen use.

Paul SP. Ensuring the Safety of Sunscreens, and Their Efficacy in Preventing Skin Cancers: Challenges and Controversies for Clinicians, Formulators, and Regulators. Front Med (Lausanne) 2019; 6:195. [PMID: 31552252 PMCID: PMC6736991 DOI: 10.3389/fmed.2019.00195] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2018] [Accepted: 08/20/2019] [Indexed: 12/17/2022] Open
Abstract
When people think about sun-protection or prevention of skin cancer, sunscreens readily come to mind. Sunscreen effectiveness is tested in vivo by the ability to prevent erythema of skin, yet testing methods vary between markets, and many sunscreens fail to achieve their claims. This article discusses the mechanism of action of sunscreens, Sun Protection Factor (SPF), safety concerns and the challenges for regulators. Many sunscreens that prevent erythema do not provide adequate protection as they contain anti-inflammatory agents; others have ingredients whose risks have not been fully evaluated. This article reviews the imperfect science behind sunscreens and points out the gaps in knowledge regarding safety, efficacy, public knowledge, and perception. Regulations vary between countries and only adds to the confusion. To truly prevent skin cancer, clinicians, formulators and regulators need to come together to research more and improve public education.

Skiljevic D, Sreckovic L. Ultraviolet radiation exposure among Belgrade high school students: analysis of knowledge, attitudes and behaviour. J Eur Acad Dermatol Venereol 2019; 33 Suppl 2:63-75. [PMID: 30811695 DOI: 10.1111/jdv.15312] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2018] [Accepted: 09/20/2018] [Indexed: 12/23/2022]
Abstract
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.

Abstract
OBJECTIVE This study aimed at collecting representative national data on the use of sunglasses on sunny summer days during leisure time or work as well as identifying population and professional groups with a pronounced lack of preventive measures to avoid sun-induced eye damage. MATERIAL AND METHODS Within the representative National Cancer Aid Monitoring, data on the use of sunglasses during leisure time was assessed among 3000 individuals aged 14-45 years in 2015, as well as on the use during outdoor work among 485 workers aged 14-45 years in 2016. Associations between the use of sunglasses and sociodemographic characteristics were assessed with the χ2-test. Additionally, descriptive and bivariate methods were used to assess connections between the use of sunglasses at work and each professional group. RESULTS While more than half of the general population normally or often wear sunglasses on a sunny summer day, only one third of outdoor workers do so. While approximately every seventh individual surveyed never wears sunglasses during leisure time, among outdoor workers it is one out of three. The use during leisure time increases with age. DISCUSSION Use of sunglasses during work could be supported by targeted information on UV-induced eye damage by ophthalmologists and company physicians with additional support from accident insurances and employers. Concerning preventive measures occupational groups such as landscapers, farmers and bricklayers who are strongly exposed to sunlight but rarely wear sunglasses are important groups.

Abstract
This study aimed to determine the prevalence of vitamin D insufficiency among Thai dermatologists compared with the general working-age population in Bangkok. A cross-sectional study was conducted in healthy Thai physicians who had at least 1 years' experience in dermatology practise and a subsample of the general Thai population from the Fourth National Health Survey. Serum 25-hydroxyvitamin D (25[OH]D), a combination of 25(OH)D2 and 25(OH)D3, levels in both groups were measured using liquid chromatography coupled with mass spectrometry. The majority of dermatologists were of Fitzpatrick skin type III (n = 61, 61.3%) or IV (n = 32, 33.3%). The mean serum 25(OH)D and 25(OH)D3 levels were 18.9 and 18.2 ng/mL, respectively, whereas the corresponding levels in the general population were 26.5 and 25.8 ng/mL. None of the dermatologist had serum 25(OH)D sufficiency (>30 ng/mL), 38 (38.78%) had vitamin D insufficiency (20-30 ng/mL) and 60 (61.22%) had vitamin D deficiency (<20 ng/mL). The frequency of vitamin D deficiency in dermatologists was significantly higher than in the general population (61.2% vs 19.2%, P < 0.001). Ninety percent of dermatologists used sunscreen daily and spent time mostly indoors. Dermatologists used physical sun-protection more than half of the time when outdoors, for example, a book or paper as a sunshade (70.3%), an umbrella (48.4%), a long-sleeved shirt (20.4%) or a hat (9.7%). In conclusion, dermatologists showed a remarkably high prevalence of vitamin D deficiency which may be due to inadequate exposure to sunlight, regular use of sunscreen and practicing various sun-protection activities.
