Cluster Randomized Trial: Sun Protection Intervention 'Clever in Sun and Shade for Preschools'-Effectiveness and Dissemination. CHILDREN-BASEL 2021; 8:children8080651. [PMID: 34438542 PMCID: PMC8391804 DOI: 10.3390/children8080651] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 07/23/2021] [Accepted: 07/24/2021] [Indexed: 11/22/2022]
Abstract
Skin cancer is one of the most common types of cancer and UV radiation is one of the main risk factors. Therefore, sun protection, especially in childhood, is strongly recommended. We examined the effectiveness of the ‘Clever in Sun and Shade for Preschools’ program (CLEVER) in promoting sun protection behavior among preschool staff (trial registration: DRKS00023468) and describe its dissemination. Within a cluster randomized trial with 24 preschools (n = 273 staff members) stating a high need for sun protection measures, an educational workshop for preschool staff and a project kit with materials applicable in preschool groups was provided. Staff members of preschools taking part in CLEVER report significantly stronger sun protection behavior to avoid the sun (effect size [ES] 0.70, 95% confidence interval [CI] 0.04 0.71, p < 0.05) and less perceived impediments to avoid the sun (ES −0.56, CI −0.82 −0.17, p < 0.01) after 12 months as well as higher self-efficacy to avoid the sun (ES 1.09, CI 0.39 1.07, p < 0.001) and to use sunscreen (ES 0.71, CI 0.03 0.88, p < 0.05) after 1 month. Compared to the control group, there was no significant effect on sunscreen use and further psychosocial outcomes. The effectiveness of CLEVER may be underrated due to a high drop-out rate. Within three years, an enhanced free-of-charge program kit, including a media-based workshop and materials, had reached over 4000 preschools, i.e., 7.1% of all daycare centers in Germany. The results show that CLEVER can strengthen sun protection, offer high-quality information at low cost, and is easily disseminable.

Abstract
Objective: Cancer risk reduction messages are a part of cancer control efforts around the world. The complex reality is that risk factors differ for different types of cancer, making clear communication of desired behavioural changes more difficult. This study aims to describe awareness of risk factors for breast, bowel, cervical, prostate and lung cancer and cutaneous melanoma among New Zealanders in 2014/15 and identify changes in awareness since 2001. Methods: Two national telephone surveys, the first (CAANZ01) conducted in 2001, included 438 adults (231 females and 207 males, 64% response rate). The second, conducted in 2014/15 (CAANZ15), included 1064 adults (588 females and 476 males, 64% response rate). Results: In 2014/5, most participants could identify evidence-based risk factors for lung cancer and melanoma. In contrast, many participants were unable to name any risk factors (evidence-based or otherwise) for bowel (34.8%), breast (48.8%), cervical (53.9%) and prostate cancer (60.9%). Between 2001 and 2014/5 there were increases in the proportion of individuals identifying sunbeds as increasing melanoma risk, and alcohol consumption and family history as increasing risk for bowel and breast cancer. Conclusions: Effective communication of risk information for specific cancers remains a challenge for cancer control. Although some positive changes in awareness over the 14 year period were observed, there remains substantial room for progressing awareness of evidence-based risk factors.

Abstract
The study's purpose was to select/refine measures assessing psychosocial constructs associated with skin cancer risk/protective behaviors. Cognitive interviewing was conducted with twenty participants locally, and a survey was conducted with 965 adults aged 18-25 years at moderate to high risk of developing skin cancer, recruited nationally online. Psychosocial measures assessed variables from the Integrative Model of Behavior Prediction. As a result of expert review and cognitive interviewing, items were removed, added, and/or made simpler, more personal, consistent, and less ambiguous. A factor analysis resulted in 14 scales and adequate model fit. Internal reliability and test-retest reliability was acceptable to good. Correlations among the psychosocial and behavioral variables were generally significant and in expected directions, demonstrating convergent validity. We have refined measures that assess important psychosocial constructs associated with skin cancer-related behaviors, that research participants can understand and complete successfully, and that are reliable and demonstrate evidence for validity.

Abstract
OBJECTIVES To explore whether knowledge about the harms of ultraviolet radiation (UVR) influences UK university students' sun-related behaviours and examine in depth their attitudes towards: sun protection, natural and artificial tanning behaviours. DESIGN Qualitative methodology with 15 semistructured, individual interviews. Thematic analysis using the Framework Method with analyst triangulation and member validation. SETTING One university in the West Midlands, UK. PARTICIPANTS 15 Caucasian male (n=4) and female (n=11) students, aged 18-22 years, from a UK university. Participants were recruited using convenience sampling from the university's main campus followed by purposive sampling for: gender, course and sun-related behaviours. RESULTS Five main themes emerged: (1) knowledge of UVR; (2) sun-protection practices; (3) attitudes towards tanning; (4) external influences and (5) internal influences. All students knew the associated skin cancer risks from the sun and sunbed use, but this did not appear an important influence in their sun-related behaviours. Body image strongly motivated sun-protection practices and the desire to tan naturally or artificially, across both genders. However, participants' final decision-making appeared to be influenced by their beliefs that practising known harmful sun-related behaviours would not affect them or the perceived susceptibility to sunburn. Beliefs about sunbathing and sunscreen use prompted improper use of sun protection and inadvertently caused more harmful practices. Participants' peers, family and the media had dual roles influencing the development of attitudes towards sun protection and tanning, which contributed to how participants behaved in the sun and their engagement in tanning methods. CONCLUSIONS Knowledge about the risk of skin cancer associated with UVR did not strongly influence sun-related behaviours, whereas body image appeared as a key motivator. Attitudes towards sun protection and tanning stemmed from the media, peers and family, and particularly from childhood habits. Public health strategies may benefit from appearance-related skin cancer prevention campaigns, encouraging safer parental sun-related habits and correcting sun-related misconceptions.

Abstract
Despite residing in a country that has the highest rates of skin cancer in the world, little is known about the knowledge, attitudes and sun protection practices of first generation Australian-born individuals with olive and darker skin types. Six focus groups with first generation Australian-born individuals of Asian, Mediterranean, Middle Eastern and Indian background were conducted. Participants had good knowledge of the dangers of skin cancer. Most correctly perceived darker skin types as protective and believed they were at low risk of skin cancer. Most participants could recall high profile mass media sun protection campaigns. Several participants suggested that greater representation of ethnic minorities and/or individuals with darker skin types would increase the personal relevance of campaigns. Beliefs that sun protection is not necessary on the basis of skin type highlights the need for further studies to explore fundamental differences in attitudes and practices between those with olive and darker skin and the general Australian population.

Abstract
Ultraviolet radiation (UVR) poses a major risk for outdoor workers, putting them at greater risk for skin cancer. In the general population, the incidence of both melanoma and nonmelanoma skin cancers is increasing. It is estimated that 90% of skin cancers in Canada are directly attributable to UVR exposure, making this cancer largely preventable with the appropriate precautions. A scoping review was conducted on the barriers and facilitators to UVR safety in outdoor workers to elucidate why these precautions are not in use currently. We discuss these results according to the Hierarchy of Controls as a means to outline effective and feasible prevention strategies for outdoor workers. In doing so, this review may be used to inform the design of future workplace interventions for UVR safety in outdoor workers to decrease the risk of skin cancer in this vulnerable population.

Abstract
BACKGROUND Almost all skin cancers are the result of overexposure to UV radiation and could be prevented by adhering to a number of simple behavioural guidelines to minimise exposure to the sun. The present study examined trends in sun-protection behaviour among adults living in Western Australia, a region with high levels of UV radiation. METHODS During five summers from 2008 to 2012, 2076 Western Australian adults participated in annual, cross-sectional telephone surveys that assessed how often they engaged in a range of sun-protection behaviour (seeking shade, staying inside and wearing a hat, protective clothing, sunscreen or sunglasses). RESULTS Apart from an increase in sunscreen use and a consistently high use of sunglasses, most sun-protection behaviour remained stable at moderate levels during the 5-year period. Seeking shade, staying inside and wearing a hat were all practised at levels ranging between 'sometimes' and 'usually' on sunny days in summer during peak UV hours, with little to no variability across the survey years. Wearing protective clothing was the least frequent behaviour across all survey years and was significantly lower in the most recent survey year relative to baseline. CONCLUSIONS Further efforts are required to encourage greater enactment of sun-protection behaviour, especially on the use of protective clothing and seeking shade during periods of high UV radiation.

Abstract
PURPOSE Skin cancer is the most common cancer in the US, and its incidence is increasing. The major risk factor for skin cancer is exposure to ultraviolet radiation (UV). Young adults tend to expose themselves to large amounts of UV and engage in minimal skin protection, which increases their skin cancer risk. Interventions are needed to address risk behaviors among young adults that may lead to skin cancer. The nternet offers a cost-effective way to widely disseminate efficacious interventions. The current paper describes the development of an online skin cancer risk reduction intervention (UV4.me) for young adults. PROCEDURES The iterative development process for UV4.me followed best-practice guidelines and included the following activities: individual interviews, focus groups, content development by the expert team, acceptability testing, cognitive interviewing for questionnaires, quality control testing, usability testing, and a pilot randomized controlled trial. Participant acceptability and usability feedback was assessed. PRINCIPAL RESULTS The development process produced an evidence-informed intervention that is individually-tailored, interactive, and multimedia in nature based on the Integrative Model of Behavior Prediction, a model for internet interventions, and other best-practice recommendations, expert input, as well as user acceptability and usability feedback gathered before, during, and after development. MAJOR CONCLUSIONS Development of an acceptable intervention intended to have a significant public health impact requires a relatively large investment in time, money, expertise, and ongoing user input. Lessons learned and recommendations are discussed. The comprehensive process used may help prepare others interested in creating similar behavioral health interventions.

Abstract
Non-melanoma skin cancer is a common and costly cancer in agricultural populations. Prevention and early detection are an effective way to decrease the burden of disease and associated costs. To examine sun exposure and skin protection practices in agricultural workers and farmers a thematic review of the literature between 1983 and 2014 was undertaken. Comparison between studies was complicated by differences in study design, definitions of skin protection, and analytic methods used. Farmers are the most exposed to harmful ultraviolet (UV) radiation of all outdoor workers and the level of reported skin protection by farmers is suboptimal. Years of public health campaigns have failed to adequately address farmers' specific needs. Increased rates of skin cancer and subsequent higher costs are expected. Estimates of sun exposure and skin protection practice indicate that protective clothing is the most promising avenue to improve on farmers' skin protection. Early detection needs to be part of public health campaigns. This review explores the quantitative data about Australian farmers and their skin protective behaviours. We investigate what the documented measurable effect of the public health campaign Slip!Slop!Slap! has had on agricultural workers and farmers and make recommendations for future focus.

Abstract
OBJECTIVE Chemopreventive approach with natural products, particularly plants and plant-derived ones, is receiving increasing attention for their effective role against cancer without any palpable side effects. In this study, efficacy of ethanolic extract of Ruta graveolens (RG) on skin melanoma cells (A375) in vitro and on 7,12-dimethylbenz(a)anthracene (DMBA)-induced skin cancer in vivo has been tested in Swiss albino mice. METHODS Studies on cell viability, apoptosis and autophagy induction were conducted in vitro. To check apoptosis, assays like alteration in mitochondrial membrane potential, annexin V-fluorescein isothiocyanate/propidium iodide assay and immunoblot were performed. Fluorescence microscopic and immunoblot assays were performed to confirm autophagy induction. The effects of RG were determined by evaluating body weight, tumor incidence, tumor volume and tumor burden in mice. Enzymatic and non-enzymatic antioxidant status was assessed. The role of some relevant signaling proteins was also analyzed. RESULTS RG caused death of A375 cells through induction of caspase 3-mediated apoptosis and Beclin-1-associated autophagy. Moreover, RG administration (75 mg/kg body weight) which showed no acute or chronic toxicity, showed significant reduction in the skin tumor burden of DMBA-painted mice. RG also demonstrated potent anti-lipid peroxidative and antioxidant functions during the course of skin cancer induction by DMBA. CONCLUSION Chemopreventive potential of RG was demonstrated from overall results of this study, indicating its possible use in therapeutic formulation of an effective drug to treat skin cancer.

Abstract
BACKGROUND Skin cancer and other adverse health effects result from excess solar ultraviolet radiation exposure. Sun protective practices are important interventions for skin cancer prevention, particularly when implemented early in life. Several international studies have assessed children's sun-related knowledge, attitudes and behaviours in school settings but never before in Southern Africa, where multiethnic populations exist. PURPOSE The purpose of this study is to describe the sun-related knowledge, attitudes and behaviours as self-reported by South African primary schoolchildren and consider the roles of sex and skin type. METHODS A randomly selected sample of 707 schoolchildren from 24 government, urban schools in all nine provinces of South Africa were surveyed regarding their sun-related knowledge, attitudes and behaviours. RESULTS Approximately 56% of students reported experience of sunburn last summer and 59% stated that they had got a suntan. Many students (64.5%) believed that one could protect oneself from getting skin cancer by avoiding getting sunburnt. Other means reported to do so by the students were to use sunscreen (65.4%), stay out of the summer sun (48.0%), cover up with clothing (45.5%) and eat the right foods (38.0%). Only about a quarter of the students (22.4%) wrongly agreed that it is safe to get sunburnt once or twice a year. Few students (8.7%) agreed that they like to have a suntan because they feel healthier and agreed that they think a suntan makes them feel more attractive to others (17.3%). Few also agreed that most of their friends (16.1%) and family (14.2%) think that a suntan is a good thing. Children reporting to have white/light brown skin (69.4%) were more likely to agree that they used sunscreen to protect themselves from getting sunburnt compared with children having brown/dark brown/black skin (54.8%) (P = 0.0005). CONCLUSION South African schoolchildren at urban government schools do have some knowledge about sun protection, and they do have some positive sun behaviours; however, the reported occurrence of sunburn, a risk factor for skin cancer, was relatively high. There were few differences in responses by sex and some differences by skin type. These findings are important for the development of appropriate sun protection programmes aimed at schoolchildren in South Africa and other countries with similar multi-ethnic populations.

Abstract
Skin cancer is the most commonly diagnosed cancer in many Western countries. This systematic review provides a comprehensive overview of the relationship between skin cancer knowledge and sun-protective, exposure and tanning behaviours in the general population. A total of 34 studies, published in peer-reviewed journals over three decades, were reviewed and synthesised. Sun-protective behaviour was positively associated with skin cancer knowledge in most cases. Findings were inconsistent regarding other sun-related behaviours. Heterogeneity in measurement compromised the capacity to definitively link knowledge and sun-related behaviours. There is a need for development and utilisation of a standardised skin cancer knowledge scale, and guidelines are suggested.

While many lifestyle-related cancer risk factors including tobacco use, poor diet, and sun exposure are well recognized by the general public, the role of physical activity in decreasing cancer risk is less recognized. Studies have demonstrated gender-, race/ethnicity-, and age-based disparities in cancer risk factor knowledge; however, beliefs and geographic factors that may be related to knowledge are under-examined. In this study, we analyzed data from the 2008 Health Information National Trends Survey to determine correlates of knowledge of the relationship between physical activity and reduced cancer risk in the adult US population. We generated geographic information system maps to examine the geographic distribution of this knowledge. Results revealed that there is confusion among US adults about the relationship between physical activity and cancer risk: Respondents who believed that cancer is not preventable had significantly lower odds of knowing that physical activity reduces cancer risk (p < .001) whereas respondents who believed that cancer is caused by one's behavior had almost two times the odds of knowing that physical activity reduces cancer risk (p < .001). Those who were aware of current physical activity guidelines were also significantly more likely to know that physical activity reduces cancer risk (p < .01). Observed geographic variability in knowledge was consistent with geographic trends in obesity and physical inactivity. Correlates of cancer risk factor knowledge point to opportunities for targeted interventions.

Abstract
Protection motivation theory components were used to predict sun protection behaviors (SPBs) using four outcome measures: typical reported behaviors, previous reported behaviors, current sunscreen use as determined by interview, and current observed behaviors (clothing worn) to control for common method bias. Sampled from two SE Queensland public beaches during summer, 199 participants aged 18-29 years completed a questionnaire measuring perceived severity, perceived vulnerability, response efficacy, response costs, and protection motivation (PM). Personal perceived risk (similar to threat appraisal) and response likelihood (similar to coping appraisal) were derived from their respective PM components. Protection motivation predicted all four SPB criterion variables. Personal perceived risk and response likelihood predicted protection motivation. Protection motivation completely mediated the effect of response likelihood on all four criterion variables. Alternative models are considered. Strengths and limitations of the study are outlined and suggestions made for future research.

Abstract
PURPOSE To estimate the prevalence of sunlight exposure and sun protection behaviors and to identify the main determinants of sun protection in a representative sample of the Moroccan population. METHODS Cross-sectional survey was carried out during May 2008 among Moroccan adults aged 18 and over, using stratified cluster sampling in origin and sex. RESULTS A total of 2896 subjects were included. More than half (52.1%) of the participants were regularly exposed to the sun during midday hours (11-16 h) for more than 2h per day. Among those exposed to the sun during midday hours, 16.4% didn't use any means of protection. The subjects who were more protected were women (odds ratio=0.47, 95% confidence interval=[0.35-0.64]), rural residents (odds ratio=2.33, 95% confidence interval=[1.97-2.77]) and worker subjects and students (p<0.0001). CONCLUSION This survey has highlighted a high prevalence of sun exposure in the Moroccan population with few protection practices. It is therefore important to promote sun protection in order to maintain the incidence rate of skin cancer at its lower level.

Abstract
OBJECTIVES Acacia catechu heartwood contains significant amounts of polyphenolic compounds that exhibit powerful antioxidant activity. The purpose of this study was to evaluate the cytotoxicity of A. catechu heartwood extracts in a human epithelial carcinoma cell line (A431) and antitumour activity against DMBA/TPA induced squamous cell carcinoma in Balb/c mice. METHODS Various extracts, including aqueous, ethyl acetate, chloroform and n-hexane, were tested for cytotoxic properties on a human epithelial carcinoma cell line (A431) by using MTT, sulforhodamine B and lactate dehydrogenase leakage assays. The standardized A. catechu heartwood aqueous extract (AQCE) was further evaluated for antitumour activity against 7,12-dimethylbenz[a]anthracene (DMBA)/12-O-tetradecanoylphorbol-13-acetate (TPA) induced skin carcinoma in Balb/c mice. KEY FINDINGS The results showed that administration of AQCE showed a dose-dependent growth inhibition response, with an IC50 value of 78.56 µg/ml. Tumour incidence was significantly decreased (P < 0.001) to 30% with AQCE compared with 100% in the DMBA/TPA group. The AQCE was also found to significantly upregulate different antioxidant enzymes in skin and liver tissue. CONCLUSIONS The results suggest that AQCE may exert its chemopreventive activity by acting as an antioxidant.

Abstract
OBJECTIVES To compare online video and pamphlet education at improving patient comprehension and adherence to sunscreen use, and to assess patient satisfaction with the two educational approaches. METHODS In a randomized controlled trial, 94 participants received either online, video-based education or pamphlet-based education that described the importance and proper use of sunscreen. Sun protective knowledge and sunscreen application behaviors were assessed at baseline and 12 weeks after group-specific intervention. RESULTS Participants in both groups had similar levels of baseline sunscreen knowledge. Post-study analysis revealed significantly greater improvement in the knowledge scores from video group members compared to the pamphlet group (p=0.003). More importantly, video group participants reported greater sunscreen adherence (p<0.001). Finally, the video group rated their education vehicle more useful and appealing than the pamphlet group (p<0.001), and video group participants referred to the video more frequently (p=0.018). CONCLUSION Video-based learning is a more effective educational tool for teaching sun protective knowledge and encouraging sunscreen use than written materials. PRACTICE IMPLICATIONS More effective patient educational methods to encourage sun protection activities, such as regular sunscreen use, have the potential to increase awareness and foster positive, preventative health behaviors against skin cancers.

Abstract
Associations between the sun exposure and sun protective behaviours of adolescents and their friends were examined along with the role played by authoritative parenting and other family and peer socialisation factors. Four hundred and two adolescents (198 males, 204 females) participated in the research. It was found that these adolescents and their friends shared similar sun exposure and sun protective behaviours and had similar parenting backgrounds. Parental authoritativeness was positively associated with the use of sun protection, even after the effects of other familial and peer variables were controlled, but not with the time spent sunbathing which was associated with friends' behaviours. The theoretical and practical implications of these findings are discussed.
