Redefine photoprotection: Sun protection beyond sunburn.

Excessive exposure to ultraviolet (UV) light leads to acute and chronic UV damage and is the main risk factor for the development of skin cancer. In most countries with western lifestyle, the topical application of sunscreens on UV-exposed skin areas is by far the most frequently used preventive measure against sunburn. Further than preventing sunburns, increasing numbers of consumers are appreciating sunscreens with a medium- to high-level sun protective factor (SPF) as basis for sustainable-skin ageing or skin cancer prevention programs. However, recent investigations indicate that clinically significant DNA damages as well as a lasting impairment of cutaneous immunosurveillance already occur far below the standard of one minimal erythema dose (MED) sunburn level, which contributes to the current discussion of the clinical value of high-protective SPF values. Ex vivo investigations on human skin showed that the application of SPF30 reduces DNA damage for a day long sun exposure (24 MED) drastically by about 53% but is significantly surpassed by SPF100 reducing DNA damage by approx. 73%. Further analysis on different SPF protection levels in UV-exposed cell culture assays focusing on IL-18, cell vitality and cis/trans-urocanic acid support these findings. Whereas SPF30 and SPF50+ sunscreens already offer a solid UVB cover for most indications, our results indicate that SPF100 provides significant additional protection against mutagenic (non-apoptotic-) DNA damage and functional impairment of the cutaneous immunosurveillance and therefore qualifies as an optimized sunscreen for specifically vulnerable patient groups such as immunosuppressed patients, or skin cancer patients.

Rural-urban differences in meeting of physical activity recommendations by sun exposure and protection behaviors in the United States.

OBJECTIVE: To examine associations between sun protection behaviors and physical activity (PA) by rural and urban residence in the United States. METHODS: We analyzed data from the National Health and Nutrition Examination Survey (2013-2018), restricting to participants ages 20-59 with sun behavior data. Sunburns, sun exposure, and sun protection measures were dichotomized (yes/no): ≥1 sunburn in the past year, 2+ hour outside during workdays or non-workdays, and never/rarely/sometimes using sunscreen, wearing long sleeves, and staying in the shade. Meeting PA recommendations (yes/no) was defined as ≥150 min of vigorous/moderate or ≥ 75 min vigorous PA per week. Associations between sun behaviors and PA were analyzed using logistic regression models, which accounted for survey-weights and potential confounders, and stratified by rural-urban status. RESULTS: Rural and urban individuals meeting PA recommendations had greater odds of spending 2+ hour outside during workdays (OR: 2.26 [1.88, 2.74] and 3.95 [2.72, 5.73]) and non-workdays (OR: 2.06 [1.78, 2.38] and 3.33 [2.47, 4.46]). Among urban residents, odds of staying in the shade were lower among those who met PA recommendations (OR: 0.78 [0.66, 0.92]). We did not observe differences in sunburns or other sun behaviors by PA status, regardless of rurality. CONCLUSIONS: Meeting PA recommendations was associated with greater sun exposure in both rural and urban populations. Additional exercise location (indoors/outside) data is needed to inform PA and skin cancer prevention interventions to reduce unintended increases in sun exposure and reductions in PA, respectively, especially among rural populations.

Skin cancer prevention in extreme sports: Intervention in a 24-h race.

INTRODUCTION: Excessive sun exposure and sunburns are the main preventable causes of skin cancer. The growing popularity of outdoor sports in developed countries has motivated the objective of this work to study the risk of photoexposure and the skin cancer prevention needs of athletes in an extreme race and evaluate an intervention targeted at this population. METHODS: An observational study was conducted during the XXIII edition of the 101 km de Ronda race, which consisted of trail running and mountain biking categories. Environmental and personal dosimetry, monitoring of meteorological conditions, evaluation of the athletes' photoprotection and skin examination habits, a dermatological checkup, and a satisfaction questionnaire were performed. RESULTS: The ultra-endurance race was carried out under adverse conditions (maximum ultraviolet index (UVI) = 9.2, temperatures above 30°C, and relative humidity >35%). The mean effective erythema dose received by race athletes (n = 11) was 2959.2 ± 404.2 J/m2 , equivalent to 29.6 standard erythema doses (SED). The CHACES questionnaire (n = 1145) showed a sunburn rate of 58% and poor protective habits: 62.9% of athletes do not usually use sunscreen and 67.2% do not self-examine their skin. Actinic keratoses (4.7%) and suspicious skin cancer lesions (4.2%) were found in dermatologic screening exams (n = 170). On the satisfaction questionnaire (n = 111), this intervention was rated as excellent (95.5%). CONCLUSION: This research highlights the extreme risk of photoexposure that athletes are subjected to during ultra-endurance competitions. In the same way, it shows the need to carry out interventions aimed at the acquisition of healthy photoprotection habits and skin surveillance in this target group.

Skin cancer survivorship and sun protection behaviors in the United States.

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.

Are Welsh primary schools Sunproofed? Results of a national survey, part 1: scoping the landscape of sun safety policies in Wales.

BACKGROUND: Schools with formal sun safety polices generally show better sun safety practices than schools without. OBJECTIVES: To understand the extent to which Welsh primary schools have sun safety policies; to identify the key characteristics of policies; to assess whether policy adoption varies by school characteristics; and to consider what support schools need to develop sun safety policies. METHODS: An online multiple-choice survey on sun safety was distributed to all 1241 primary schools in Wales. RESULTS: In total, 471 (38.0%) schools responded. Of these, 183 (39.0%) reported having a formal sun safety policy. Welsh medium schools (P = 0.036) and schools in North Wales (P = 0.008) were more likely to report having a policy. Schools with a higher percentage of pupils receiving free school meals (P = 0.046) and with lower attendance rates (P = 0.008) were less likely to report having a sun safety policy. The primary reasons for schools not having a policy included being 'not aware of the need' (34.6%); 'need assistance with policy or procedure development' (30.3%); and 'not got around to it just yet' (26.8%). CONCLUSIONS: With less than half of schools reporting a sun safety policy and variation in the presence/absence of a policy by school characteristics, our survey revealed inconsistency in formal sun safety provision in Welsh schools. The findings also suggest that schools are unaware of the importance of sun safety and need support to develop and implement policies. This snapshot of the current situation in primary schools in Wales provides a basis upon which the comprehensiveness, effectiveness and implementation of sun safety policies can be further evaluated.

Skin Cancer Awareness and Knowledge About Sun Protection Practices in Solid Organ Transplant Recipients: Patient Survey Study.

BACKGROUND: Adequate sun protection practices in chronically immunosuppressed patients can minimize the burden of the most common type of skin cancer in this population. In addition, early recognition of skin cancer by patients can lead to decreased morbidity, and possibly mortality from the disease. Nevertheless, there are significant gaps in the knowledge of sun protection measures and early recognition of skin cancer. OBJECTIVE: The aim of this study is to determine the risk factors of solid organ transplant recipients (SOTRs) for developing skin cancer and their sun exposure education and behavior post-transplantation. MATERIALS AND METHODS: This study evaluates the responses of 107 SOTRs on their outlooks and beliefs of sunscreen usage, skin cancer, and sun exposure knowledge. RESULTS: Our study identified several significant risk factors for the development of actinic keratosis or keratinocyte carcinoma in SOTRs including history of sunburn before age 18, blue eyes, history of tanning bed use, performing monthly skin exams, ability to identify precancerous skin lesions, and history of previous skin examinations. CONCLUSION: A patient-centered approach needs to be used to properly educate patients on effective ways to reduce excessive sun exposure. Regular skin examinations, and patients continued education are necessary components in reducing the burden of skin cancer in SOTRs.

Photoprotection: Current developments and controversies.

This review aimed at summarizing some of the key points that were discussed during the photoprotection session at the International Forum of Dermatology in 2022. This international conference was designed to address prominent topics of clinical dermatology in a holistic way, allowing to articulate multiple viewpoints. Therefore, this review does not claim to be exhaustive, but is instead intended to give an overview of recent developments and ongoing controversies in the field of photoprotection. Cumulative ultraviolet radiation (UVR) exposure is the major aetiological factor in the development of photoageing, photoimunosuppression and photocarcinogenesis. UVA (320-400 nm) penetrates into the dermis and damages DNA and other intracellular and acellular targets primarily by generating reactive oxygen species (ROS). It is the major contributor to photoageing, characterized by fine and coarse wrinkles, dyspigmentation and loss of elasticity. UVB (290-320 nm) is responsible for sunburns through direct damage to DNA by the formation of 6-4 cyclobutane pyrimidine dimers (CPDs) and pyrimidine 6-4 pyrimidone photoproducts. Both UVA and UVB exposure increase the risk of basal cell carcinoma, squamous cell carcinoma and melanoma. In recent years, visible light (VL; 400-700 nm) has also been implicated in the exacerbation of conditions aggravated by sun exposure such as hyperpigmentation and melasma. Photoprotection is a critical health strategy to reduce the deleterious effects of UVR and VL. Comprehensive photoprotection strategies include staying in the shade when outdoors, wearing photoprotective clothing including a wide-brimmed hat, and sunglasses, and the use of sunscreen. Due to the absorption of UV filters, the safety of sunscreens has been questioned. Newer sunscreens are becoming available with filters with absorption even beyond the UV spectrum, offering enhanced protection compared with older products. Prevention of photocarcinogenesis, sun-induced or sunlight-exacerbated hyperpigmentary conditions and drug-induced photosensitivity is an important reason for adopting comprehensive photoprotection strategies.

Factors Influencing Patient Selection of Sunscreen.

Sunscreen is an essential component of sun protection. The most important characteristics for patient selection of sunscreens have not been evaluated. A cross-sectional survey study was performed at an academic dermatology office. The sunscreen characteristic chosen most frequently was SPF (75.2%). Fewer patients selected broad-spectrum (20.7%) and water-resistance (22.7%). There remains a gap in patient knowledge regarding AAD recommendations for sunscreen characteristics and educational initiatives may be required.

DermTok: Who's Talking Sun? A Cross-Sectional Analysis of Sun Protection Content on TikTok.

Despite the widespread interest in dermatology on TikTok, studies have shown most related videos are not produced by board-certified dermatologists (BCDs) or other health professionals. To see if this trend extended to sun protection, we examined TikTok videos associated with sun safety to determine the proportion produced by BCDs. From August 25, 2023, to August 27, 2023, investigators input the following hashtags into the TikTok search bar: #sunscreen, #sunprotection, #spf, #skincancer, and #skinprotection. The top 100 videos in each category were analyzed and categorized based on the content creator. Additionally, we assessed whether videos explicitly addressed skin of color (SOC). Of the analyzed videos, only 16.6% originated from BCDs. Beauty bloggers/bloggers were the most prevalent creators in this category (38.7%), followed by patients/consumers (33.7%). Only 2.8% of the videos pertained to SOC patients. This highlights a gap in the type of educational content generated by dermatologists on TikTok, with sun safety being a potential subject to target within social media. Additionally, the small representation of videos addressing SOC patients underscores the need for more diverse and inclusive educational skincare content on TikTok.J Drugs Dermatol. 2024;23(7):571-574. doi:10.36849/JDD.8179.

Sunscreen Practices and Preferences of Skin of Color Patients.

Sunscreen is an essential way to protect against photodamage from ultraviolet (UV) radiation. Despite the recognized benefits of sunscreen in preventing skin damage from UV light, its use varies across different patient groups. This cross-sectional, questionnaire-based study aims to uncover the sunscreen usage patterns, preferences, and barriers among non-Hispanic White (NHW) and skin of color (SOC) individuals. Our findings demonstrate that NHW individuals are more likely to wear sunscreen daily (31% NHW vs 25% SOC) and reapply sunscreen at least once a day (76% NHW vs 45% SOC) compared with SOC individuals. SOC individuals demonstrate a willingness to use sunscreen, but they face barriers such as cost (2% NHW vs 16% SOC), lack of knowledge in finding suitable products (22% NHW vs 41% SOC), and concerns about white cast (7% NHW vs 25% SOC). SOC individuals are less likely to know the difference between mineral and chemical sunscreen (49% NHW vs 29% SOC), less likely to learn about sunscreen from dermatologists (36% NHW vs 22% SOC), and more likely to prefer sunscreen from brands owned by people of color (13% NHW vs 47% SOC).  In addition to analyzing the broader categories of NHW and SOC, subgroup analysis was conducted on specific subgroups, including Black, Asian, and Hispanic groups. Herein, we highlight differences in motivations, sunscreen preferences, sources of information, and knowledge levels about sun protection between NHW and SOC individuals. By uncovering the unique needs and challenges faced by SOC individuals, we aim to improve culturally competent patient education and promote effective sun protection practices across diverse populations. J Drugs Dermatol. 2024;23(6):456-462.     doi:10.36849/JDD.8268.

Comparison of Characteristics Influencing Patient Selection of Sunscreen Between Urban and Rural Regions in the United States.

Sunscreen greatly reduces the risk of skin cancer and is recommended as a critical component of sun protection. There is limited literature on patient preferences for sunscreen characteristics. A cross-sectional survey was administered to patients in an urban city and rural area in the United States. Sun Protection Factor (SPF) was consistently the most important factor for patients when selecting sunscreen. However, numerous preferences for sunscreen characteristics vary between the 2 regions, including dermatologist recommendation, texture, ingredients, cost, broad-spectrum, and brand. Gaps in patient knowledge of sunscreen recommendations may be present and further educational programs may be necessary. J Drugs Dermatol. 2024;23(8):e171-e172. doi:10.36849/JDD.8449.

Legislative review and recommendations for improving sun protection in schools.

BACKGROUND: Sun exposure in schools can account for a large portion of childhood sun exposure before the age of 20 years, yet legislation in the United States is lacking to properly protect children. Schools serve as a foundational resource to introduce and implement sun-safe practices in the youth population. METHODS: Federal and state legislation relating to the access of sunscreen, sun-protective apparel, and shade was reviewed via the website LegiScan.com. RESULTS: At the time of publication, only 25 states have legislation in place that addresses and allows sunscreen to be used in school, given its classification as an over-the-counter medication. No state has implemented legislation allowing sunglasses to be worn in school, and only two states have laws explicitly allowing hats and other sun-protective apparel at schools. In addition, the provision of shade is addressed in four states. CONCLUSIONS: With a significant portion of sun exposure occurring at schools, state and federal legislation must address sun protection for students, opening the door for expanded access and additional research related to skin cancer prevention.

A photoaging smartphone application to promote sun safety behaviors among youth in late childhood and adolescence.

BACKGROUND: Ultraviolet (UV)-exposure behaviors can directly impact an individual's skin cancer risk, with many habits formed during childhood and adolescence. We explored the utility of a photoaging smartphone application to motivate youth to improve sun safety practices. METHODS: Participants completed a preintervention survey to gather baseline sun safety perceptions and behaviors. Participants then used a photoaging mobile application to view the projected effects of chronic UV exposure on participants' self-face image over time, followed by a postintervention survey to assess motivation to engage in future sun safety practices. RESULTS: The study sample included 87 participants (median [interquartile (IQR)] age, 14 [11-16] years). Most participants were White (50.6%) and reported skin type that burns a little and tans easily (42.5%). Preintervention sun exposure behaviors among participants revealed that 33 (37.9%) mostly or always used sunscreen on a sunny day, 48 (55.2%) experienced at least one sunburn over the past year, 26 (30.6%) engaged in outdoor sunbathing at least once during the past year, and zero (0%) used indoor tanning beds. Non-skin of color (18 [41.9%], p = .02) and older (24 [41.4%], p = .007) participants more often agreed they felt better with a tan. Most participants agreed the intervention increased their motivation to practice sun-protective behaviors (wear sunscreen, 74 [85.1%]; wear hats, 64 [74.4%]; avoid indoor tanning, 73 [83.9%]; avoid outdoor tanning, 68 [79%]). CONCLUSION: The findings of this cross-sectional study suggest that a photoaging smartphone application may serve as a useful tool to promote sun safety behaviors from a young age.

Behaviorally segmented audiences for managing sunscreen chemical pollution risk in protected coastal natural resource areas.

This audience segmentation of visitors at coastal parks in Hawaii and North Carolina addresses an emergent natural resource management concern and risk to aquatic ecosystems: sunscreen chemical pollution. Four audiences were identified that correspond to different behavioral profiles: sunscreen protection tourists, multimodal sun protection tourists, in-state frequent park visitors, and frequent beachgoers who skip sunscreen. The second-largest audience, sunscreen protection tourists, represents 29% of visitors at Cape Lookout National Seashore and 25% at Kaloko-Honokohau National Historical Park. This group ranks of most concern for chemical pollution because they use sunscreen, but not typically mineral formulations or other methods such as protective clothing, and they have lower levels of sunscreen chemical issue awareness. The identification of similar audience segments across regions with differing cultural characteristics and sunscreen regulation status suggests the robustness of the model and its indicator variables, with implications for both environmental protection and public health. Further, coastal visitors' interest in enacting pro-environmental sun protection behaviors during their next park or beach visit indicates the potential for natural resource managers to holistically address risks in both domains through targeted interventions with audiences of most concern.

Sun-related knowledge and practices in Irish construction and agricultural workers.

BACKGROUND: Agricultural and construction workers spend much of their work time outdoors and have higher risks of developing skin cancer when compared to indoor workers. However, there is limited research on ultraviolet radiation (UVR) exposure knowledge, sun safety practices and constraints within these occupational groups in Ireland. AIMS: This study aimed to examine self-reported time spent outdoors in a sample of Irish agricultural and construction workers; to describe and compare UVR exposure knowledge, safety practices and perceived constraints in both occupational groups, and to assess the association of demographic, personal and occupational factors with sun-related knowledge, practices and perceived constraints. METHODS: Agricultural workers (n = 154) and construction workers (n = 467) completed a questionnaire, which measured solar UVR exposure knowledge, safety practices, and perceived constraints to sun personal protective equipment and sunscreen use in addition to demographic, personal, and workplace characteristics. Mann-Whitney and Kruskal-Wallis tests were used to examine differences in knowledge, practices and perceived constraints by these characteristics. RESULTS: Both groups spend a significant proportion of their working week outdoors (25 hours per week on average). Although participation in sun safety training was high for both groups, UVR exposure knowledge and sunscreen use were low, and annual rates of reported sunburn were high. Knowledge, practices and perceived constraints also differed significantly according to demographic, personal, occupational and workplace characteristics. CONCLUSIONS: In addition to training by employers and advisory groups, interventions are required to address perceived barriers that impede the uptake and usage of control measures that can lower risk.

Evaluating How a School-Based Skin Cancer Prevention Program Can Change Behavior Among North Carolina Highschoolers.

The incidence of skin cancer has risen steadily over recent decades. Childhood and adolescent sun exposure remains a critical risk factor in skin cancer development, making education of high schoolers imperative for promoting sun-safe behaviors. Medical students in North Carolina recognized this need and designed a skin cancer education program focused on portraying skin cancer in individuals with all Fitzpatrick skin phototypes. Eighty-seven students completed the pre-survey, and 84 completed the post-session survey. In the post-survey, 88% of students listed actionable behavioral changes they plan to make following the presentation. Following an educational session, students were able to demonstrate their new knowledge and provide meaningful behavioral changes. This program navigated challenges posed by COVID-19 and addressed the need for more inclusive skin cancer educational material.

The Impact of Acculturation on Skin Cancer Risk and Protective Behaviors in Hispanic Populations.

The US Hispanic population faces rising skin cancer risks and poorer clinical outcomes, despite lower incidence rates. Acculturation, adopting elements of the dominant culture, may influence skin cancer attitudes and behaviors among Hispanics. We systematically reviewed PubMed articles from 2000 to 2023. Peer-reviewed English articles that assessed the relationship between acculturation and skin cancer in the Hispanic population were included. Andreeva et al. observed that lower acculturation levels correlated with increased use of shade and protective clothing (P < 0.05). More acculturated Latinos were more likely to use sunscreen, but this association weakened after adjusting for covariates (P > 0.48). Heckman et al. highlighted significant differences in skin cancer concern among Hispanic youth, with less acculturated individuals expressing greater worry (P < 0.05). Coups et al. found that higher acculturation was linked to less sun protective clothing usage and more frequent sunburns. Their subsequent online survey indicated that English-acculturated Hispanics engaged less in protective behaviors. Viola et al. reported that English-acculturated Hispanics perceived greater suntan benefits and had lower perceptions of skin cancer risk, severity, and concerns about photo-aging, along with higher melanoma risk factors, compared to Spanish-acculturated Hispanics. Acculturation influences skin cancer attitudes and behaviors in Hispanics. Tailored interventions based on acculturation levels are essential to reduce skin cancer risk. For example, educating English-acculturated Hispanics about skin cancer risks and prioritizing knowledge dissemination for Spanish-acculturated individuals may be effective approaches. These findings emphasize the need for targeted skin cancer prevention efforts to address disparities among US Hispanics.

The Knowledge, Attitudes, and Practices of Parents Regarding Sun Protection for Their Children.

OBJECTIVE: To evaluate the knowledge, attitudes, and practices of parents toward protecting their children against skin cancer and the sun. METHODS: This cross-sectional study was performed in Turkey from March through October 2022. The authors used a questionnaire investigating the parents' and children's characteristics, attitudes, and practices toward sun protection and the Skin Cancer and Sun Knowledge (SCSK) scale to collect data. RESULTS: Of 465 parents, 60.2% were women, 83.2% were light-skinned, 20.2% perceived their children as risk-free, 43.8% perceived their children as low risk in terms of skin cancer, 14.6% examined their children from head to foot, 62.3% applied sunscreen to their children, 9.7% made them wear long-sleeved clothing, 60.0% made them wear headgear, 61.1% made them remain in the shade or under a sunshade, and 32.3% made them wear sunglasses. The mean parental SCSK scale score was 14.3 ± 4.1. Scale scores were higher among those who perceived their children as being at high risk for skin cancer (P = .000), whose children had not experienced red or painful sunburn in the previous year (P = .000), and who informed their children about sun protection (P = .000). CONCLUSIONS: Although knowledge of skin cancer and solar protection was high, parental perception of the risk of skin cancer was very low, and attitudes toward skin examination were also very relaxed.

Sun protection in outdoor workers - Development and validation of standardized questionnaires for behavior and knowledge.

BACKGROUND AND OBJECTIVES: Outdoor workers are at increased risk of developing non-melanoma skin cancer. We aimed to address the lack of validated German-language measurement instruments for outdoor workers' sun safety behavior and knowledge by compiling and validating two questionnaires. PARTICIPANTS AND METHODS: By expert consensus, items for the assessment of protective behavior (OccuSun) were compiled based on existing instruments. For knowledge, a translation of the Skin Cancer and Sun Knowledge (SCSK) scale was selected. After a pre-test, a validation study including 68 outdoor workers (62% female) was conducted in 2020. RESULTS: The retest reliability was r = 0.93 (95% confidence interval: 0.86-0.96) for the protection score and rs = 0.78 (0.67-0.86) for the knowledge score. Protective behaviors were correlated with respective diary data (0.38 ≤ rs ≤ 0.74, p < 0.001) and skin pigmentation changes (-0.23 ≥ rs ≥ -0.42, 0.007 ≤ p ≤ 0.165) but not with self-reported sunburn frequency (0.21 ≥ rs ≥ -0.04). CONCLUSIONS: Among German outdoor workers, two questionnaires for the assessment of sun protection behavior (OccuSun) and knowledge (SCSK) demonstrated good reliability. The OccuSun had generally good validity. Both instruments are fit for subsequent validation to determine their sensitivity to change.

Which factors influence the participation in statutory skin cancer screenings in Germany?

BACKGROUND AND OBJECTIVES: Due to increasing skin cancer incidence, Germany implemented a statutory nationwide routine skin cancer screening (rSCS) in 2008. The present study aims (1) to analyze which patient factors are associated with the participation in rSCS in Germany and (2) to investigate reasons for nonparticipation. PATIENTS AND METHODS: Participants and nonparticipants of rSCS (≥ 35 years) were recruited in routine care in nine dermatological outpatient clinics. Reasons for (non-)participation, knowledge about skin cancer as well as clinical and socioeconomic data were obtained. Stratified by groups, descriptive analyses and binary logistic regression analyses for associations with participation were performed. RESULTS: Of the 294 rSCS participants and 162 non-participants, 46.5% were male with a mean age of 54.5 ± 12.7 years. In total, 87.1% had sunburns in childhood and 47.1% used sunbeds before. Higher age, female gender, previous sunbed use, and concern for and knowledge of skin cancer were significantly associated with previous rSCS participation. Of the non-participants, 46% were unaware of the option for free rSCS and 40% justified their nonparticipation on the basis of feeling healthy. CONCLUSIONS: The reasons for nonparticipation in rSCS, such as sociodemographic characteristics and risk behavior, should be known in order to optimize rSCS programs.
