Awareness of cancer among adolescents: A study of nine focus groups in Aotearoa New Zealand.

ISSUE ADDRESSED: One third of cancers are potentially preventable by modifying key risk factors that arise during adolescence. To help inform prevention efforts, we investigated adolescents' understanding of cancer risk factors, symptoms and signs and barriers to help-seeking. METHODS: Nine focus groups were conducted with purposefully sampled, binary-gendered friendship groups of 12 to 17-year-olds. Interviews were analysed using a qualitative descriptive method based on the topic schedule, transcripts and field notes. RESULTS: Behavioural, genetic and environmental factors were commonly explored as risk factors. Most cancer symptoms identified focused on physical indicators, such as lumps and skin appearance. Facilitators and barriers to good health choices involved both external and internal factors: education, affordability, attitudes and the social environment. Most participants indicated they would talk to trusted friends and family members about health issues, but only when the condition became 'serious'. The most common source of health information was the internet. CONCLUSIONS: Adolescents have a good understanding of behavioural risk factors, but poor knowledge of some key cancer symptoms. A support system was recognised to be a substantive factor in dealing with health issues, as were youth-focused health services. Understanding of the preventability of many cancers was not widespread with participants. SO WHAT?: The results emphasise a requirement for appropriate, affordable and accessible youth-focused health services. There is a need for age- and culturally appropriate interventions that improve knowledge of cancer symptoms. Immunisation against the viruses implicated in cervical cancer is one example of a clinical cancer prevention intervention in adolescence.

National Sporting Organisation policies: A health promotion opportunity?

ISSUE ADDRESSED: The objective was to identify whether National Sporting Organisations (NSOs) have policy documentation on healthy behaviours (smokefree, sun-protection, healthy food/beverages and alcohol) and, for organisations with such documentation, whether this was in-line with current scientific evidence of past best practice in cancer prevention. METHODS: This cross-sectional policy analysis study was performed September to December 2018 in Aotearoa/New Zealand. A content analysis was undertaken using NSO policy documents matched against a framework of key indicators for best practice within health behaviours of interest. Data analysis of the policy process was undertaken through key informant telephone interviews with NSO staff using semi-structured qualitative interviews. RESULTS: Of 96 NSOs, nearly half (49%) mentioned smokefree at least once in one of their policy documents, and 47% had an alcohol policy, although in both instances the policies lacked comprehensiveness. Two NSOs had a reasonably comprehensive sun protection policy. Seventeen had at least one specific nutrition policy/guideline. The contents of the latter were primarily related to short-term athletic performance rather than non-communicable disease prevention, specifically promoting hydration during sports participation, and food and nutrition to support sporting performance. Two NSOs had policies relating to the promotion of healthy food/nutrition more widely. For some NSOs, the lack of health-related policies was not a conscious choice but just not considered previously. Other NSOs reported they lacked resources or had other priorities. CONCLUSIONS: Although this study clearly demonstrates that many NSOs lack adequate health-related policies, this is not necessarily a conscious choice, but the result of a lack of resources, other priorities, or just that they had not considered developing policies in these areas. A number expressed support for these types of policies although it was apparent that some, particularly smaller NSOs, would require assistance in policy template development. It seems probable that the development of health-related policies will only occur if partner agencies become involved.

Generating political priority for skin cancer primary prevention: A case study from Aotearoa New Zealand.

ISSUES ADDRESSED: Skin cancer is highly prevalent but preventable, yet little research has been done on the challenges in generating political priority for skin cancer prevention. This qualitative study aimed to identify the political challenges to, facilitators of, and strategies to strengthen skin cancer prevention. The focus was on the case of Aotearoa New Zealand (NZ): a country with high skin cancer rates, but limited investment in primary prevention. METHODS: Data sources included 18 national key informant interviews and documentary analysis. Data were analysed inductively for emerging themes and framed using a conceptual framework of political priority. RESULTS: Challenges to advocates for skin cancer primary prevention include limited resources and competing priorities. Political-level challenges include a lack of quick results compared with other initiatives vying for political attention, lack of negative externalities and, in NZ, misalignment with health system priorities. Challenges in the evidence base include the perceived conflict of sun protection with Vitamin D and physical activity, the lack of data on the financial burden of skin cancer and relatively low temperatures in NZ. Facilitators include strong policy community cohesion and issue framing, and weak opposition. Promising strategies to strengthen skin cancer prevention in NZ could include network building, using framing that resonates with policy makers and addressing key knowledge gaps in NZ, such as the financial burden of skin cancer. CONCLUSION: Advocacy for skin cancer prevention faces challenges due to advocates' limited resources, political challenges such as lack of quick results and gaps in evidence. Nonetheless, the initiative encounters little opposition and can be framed in ways that resonate with policy makers. SO WHAT?: Skin cancer is highly preventable, but advocates for prevention initiatives have struggled to gain political traction. This study identifies several strategies that could help raise the political profile for skin cancer prevention.

Studying third-parties and environments: New Zealand sun-safety research.

Wearable cameras have been used to study health behaviours, but their utility in assessing third-party behaviours and the built environment is uncertain. This paper reports on the feasibility of using wearable cameras for this purpose in a study of sun-protective behaviours and shade availability during school lunch-breaks. The Kids'Cam study provided 168 children (aged 11-13 years), recruited from 16 randomly selected schools in the Wellington region of New Zealand, with wearable cameras. The devices automatically captured images every 7 s from the child's perspective. Images captured during school lunch-breaks by a random sample of 15 children who took part during terms 4 and 1 (October 2014-April 2015) were selected and assessed for usability. The feasibility of studying third-party sun-protective behaviours and school shade availability was assessed for a subset of 320 images. Of the 3492 eligible lunch-break images, 96.4% were useable; the remainders were excluded due to obstruction, blurriness or unsuitable camera position. Overall, 1278 children and 108 shade structures were observed in the sample images. The use of shade, hats, sleeves, collars and sunglasses could be determined for 97.0%, 77.2%, 74.4%, 47.6% and 54.9% of children, respectively. All shade structures could be classified according to type, and canopy composition could be assessed for 95.4% of structures. Wearable cameras are a feasible tool for assessing sun-safety, particularly shade availability, hat wearing and shade use. This methodology could be used to objectively study other third-party health-related behaviours, and other features of the built environment.

SunSmart news? Traditional media coverage of sun protection issues during springtime in New Zealand.

ISSUES ADDRESSED: Cutaneous melanomas and keratinocyte carcinomas (nonmelanoma skin cancer) are highly prevalent in New Zealand (NZ), making skin cancer a priority area for cancer control. Spring is an important time for encouraging sun-safety, due to ultraviolet radiation (UVR) levels becoming hazardous. The news media have a potential to play an important role in reminding people and emphasising the importance of sun-safety. This study aimed to describe how the traditional NZ media portrayed sun-safety and skin cancer in spring news stories. METHODS: A media monitoring company collated stories related to cancer during spring 2016. These were reviewed for inclusion and content was coded according to the cancer type described. Stories focused on skin cancer and sun protection issues were coded according to the position on the cancer control continuum. RESULTS: Skin cancer and sun-safety represented 3.6% (n = 110) of all cancer stories published. Stories mainly related to primary prevention (72%), early detection (37%) and survivorship (27%). The main risk factors identified included sun exposure (49%) and tanning (25%). CONCLUSIONS: Traditional media coverage of skin cancer remains relatively low during springtime. It is heartening to see that most stories included prevention information. SO WHAT?: Given the impact of skin cancer in NZ, and the importance of springtime as a period for behaviour change to reduce risk, there is considerable scope for increased media coverage and advocacy. Further research could usefully analyse media trends throughout the year and within specific media platforms, both traditional and new, in order to further disseminate information to the NZ public.

Cancer Information Seeking Among Adult New Zealanders: a National Cross-Sectional Study.

Organisations seeking to establish themselves as leading cancer information sources for the public need to understand patterns and motivators for information seeking. This study describes cancer information seeking among New Zealanders through a national cross-sectional survey conducted in 2014/15 with a population-based sample of adults (18 years and over). Participants were asked if they had sought information about cancer during the past 12 months, the type of information they sought, what prompted them to look for information and ways of getting information they found helpful. Telephone interviews were completed by 1064 participants (588 females, 476 males, 64% response rate). Of these, 33.8% of females and 23.3% of males (total, 29.2%) had searched for information about cancer over the past year. A search was most frequently prompted by a cancer diagnosis of a family member or friend (43.3%), a desire to educate themselves (17.5%), experience of potential symptoms or a positive screening test (9.4%), family history of cancer (8.9%) or the respondent's own cancer diagnosis (7.7%). Across the cancer control spectrum, the information sought was most commonly about treatment and survival (20.2%), symptoms/early detection (17.2%) or risk factors (14.2%), although many were general or non-specific queries (50.0%). The internet was most commonly identified as a helpful source of information (71.7%), followed by health professionals (35.8%), and reading material (e.g. books, pamphlets) (14.7%).This study provides a snapshot of cancer information seeking in New Zealand, providing valuable knowledge to help shape resource delivery to better meet the diverse needs of information seekers and address potential unmet needs, where information seeking is less prevalent.

Cancer Awareness in Aotearoa New Zealand (CAANZ), 2001 and 2015: Study Protocols.

Population cancer awareness is of interest worldwide, as efforts are made to reduce cancer incidence via changes in risk and protective behaviours. To date, few studies have described changes in awareness over time, despite significant investment in raising awareness about various cancer types and risk behaviours. This paper describes the Cancer Awareness in Aotearoa New Zealand (CAANZ) survey, a cross-sectional telephone survey of adult New Zealanders conducted in 2014/2015 (CAANZ15, n = 1064) and its comparison with a similar 2001 study (CAANZ01, n = 438). Both aimed to describe current cancer awareness among a national sample of New Zealand (NZ) adults, with additional aims for CAANZ15 being to explore emerging issues in information provision and supportive care. Follow-up studies are challenged by changes in communication technologies and, in turn, potential issues in sampling. However, given the value of information about changing awareness, pragmatic steps were taken in CAANZ15 to maximise the response rate and comparability of the surveys. A response rate of 64 % was achieved for both samples. When compared to the adult NZ population, the CAANZ15 sample tended to be older, of higher socioeconomic status and under-representative of people with Pacific, Asian or, to a lesser extent, Maori (the indigenous population of NZ) ethnicity. To compensate for possible disproportionate age-by-ethnicity (Maori/non-Maori) groups in the sample, poststratification weighting was adopted. While caution will need to be exercised in drawing conclusions from comparisons made between these two cohorts, the dearth of such studies means that insights gained should be useful for guiding reflection on future cancer control directions and the generation of new hypotheses.

Factors associated with photoprotection by body clothing coverage, particularly in non-summer months, among a New Zealand community sample.

Clothing coverage is important for reducing skin cancer risk, but may also influence vitamin D sufficiency, so associated plausible predictors require investigation. Volunteers (18 to 85 years), with approximately equal numbers by sex and four ethnicity groups, were recruited in cities from two latitude bands: Auckland (36.9°S) and Dunedin (45.9°S). Baseline questionnaire, anthropometric and spectrophotometer skin colour data were collected and weather data obtained. Percent body coverage was calculated from eight week diary records. Potential independent predictors (unadjusted p < 0.25) were included in adjusted models. Participants (n = 506: Auckland n = 334, Dunedin n = 172; mean age 48.4 years) were 62.7% female and had a median body clothing coverage of 81.6% (IQR 9.3%). Dunedin was cooler, less windy and had lower UVI levels than Auckland. From the fully adjusted model, increased coverage occurred in non-summer months (despite adjusting for weather), among Dunedin residents and Asians (compared to Europeans), during the middle of the day, with a dose response effect observed for greater age. Reduced coverage was associated with Pacific ethnicity and greater time spent outdoors. Additionally, higher temperatures were associated with reduced coverage, whereas increased cloud cover and wind speed were associated with increased coverage. Although the only potentially modifiable factors associated with clothing coverage were the time period and time spent outdoors, knowledge of these and other associated factors is useful for the framing and targeting of health promotion messages to potentially influence clothing coverage, facilitate erythema avoidance and maintain vitamin D sufficiency.

Knowledge and practice of sun protection in schools in South Africa where no national sun protection programme exists.

Interventions in primary schools that increase sun-protective behaviours and decrease ultraviolet radiation exposure, sunburn incidence and skin cancer risk can be effective. SunSmart School Accreditation Programmes (SSAP) are recommended. Prior to SSAP implementation in South Africa, we explored the feasibility of obtaining national baseline information and investigated possible associations between strategies regarding sun protection in schools and students' responses to a questionnaire. Principals from randomly selected urban government schools in all nine South African provinces completed a questionnaire and 679 students were surveyed. The mean sun-related knowledge and behaviour scores of students were 4 (range: 1-7) and 3 (range-0-8) out of 9, respectively. The mean school sun protection effort score was 4 out of 14. There were no statistically significant correlations between students' knowledge or behaviour scores and their school score. The World Health Organization recommends an SSAP to address policy, practice and curriculum changes to support sun protection of students. This cross-sectional study demonstrates the feasibility of, and need for, a larger baseline study with longitudinal, multi-variable follow-up which includes other influential factors, such as parent support. Such research could quantify the impact of the SSAP and identify which key factors influence the sun-related knowledge and behaviours of students.

Self-reported skin colour and erythemal sensitivity vs. objectively measured constitutive skin colour in an African population with predominantly dark skin.

BACKGROUND: Skin colour is an important factor in skin-related diseases. Accurate determination of skin colour is important for disease prevention and supporting healthy sun behaviour, yet such data are lacking for dark skin types. METHODS: Self-perceived, natural skin colour and sun-skin reaction were compared with objectively measured skin colour among an African population with predominantly dark skin. Unexposed skin of 556 adults (70.1% Black) was measured with a reflectance spectrophotometer to calculate an individual typology angle (°ITA). Participants reported self-perceived skin colour and erythemal sensitivity. RESULTS: There was a strong, positive monotonic correlation between self-reported and measured skin colour (Spearman ρ = 0.6438, P < 0.001), but only a weak correlation between self-reported erythemal sensitivity and measured skin colour (Spearman ρ = 0.2713, P < 0.001). Self-report biases in underestimation and overestimation of skin colour were evident. Many participants with 'dark brown' and 'black' skin had difficulty in classifying erythemal sensitivity. CONCLUSIONS: In Africa, self-reported skin colour could potentially be used in lieu of spectrophotometer measurements, but options for questions on sunburn and tanning require suitable adjustment. Our study provides evidence of range in °ITA values among residents in Africa and reinforces previous results that self-report may be reliable for determining skin colour, but not erythemal sensitivity, for dark skin individuals.

Small doses from artificial UV sources elucidate the photo-production of vitamin D.

To clarify the relation between UV exposure and vitamin D status, 201 volunteers wore personal electronic UV dosimeters during daylight hours, to record their UV exposure over a 10 week period when ambient UV levels were significantly less than the summer maxima. Blood samples to determine serum 25-hydroxyvitamin D3 [25(OH)D3] levels were taken at the end of week 4 and week 8. Participants were then given a single full-body exposure of approximately 2 SED from one of four artificial UV sources with different spectral outputs and a further blood sample taken at study completion, nominally week 10. The artificial UV exposure reversed the mean seasonal decline in 25(OH)D3. Increases in 25(OH)D3 from week 8 to week 10 were related to total UV exposure, including the ambient sun exposures. These exposures were weighted by the erythemal action spectrum and separately for three different action spectra for pre-vitamin D production. For the erythema weighting function, 25(OH)D3 increased 1.78 ± 0.25 nmol per litre per SED, a value consistent with other studies. Any differences due to age, BMI, gender, and skin reflectance were not statistically significant. Ethnicity differences were the only significant factor, with Asians producing the least vitamin D, and Maori the most. There was no statistically significant improvement in consistency between sources for any of the three pre-vitamin weightings compared with that for erythema. Further work is needed to verify which vitamin D action spectrum is most appropriate. Nevertheless, these small doses of UV from artificial sources were helpful in quantifying the relationship between UV exposure and vitamin D status among the New Zealand population.

Children's sun exposure and sun protection: prevalence in Australia and related parental factors.

BACKGROUND: Reducing childhood exposure to ultraviolet radiation is important to minimize lifetime skin cancer risk. OBJECTIVES: We sought to describe the prevalence of children's sun-related behaviors and associated parental and other factors. METHODS: In weekly cross-sectional telephone interviews during summer, 1140 parents/guardians of children aged 0 to 11 years were recruited. Parents provided proxy reports for one of their children. Key questions related to weekend sun protection and sunburn, parent's sun-related attitudes, and demographic characteristics. Potential predictors of children's sun protection and sunburn were analyzed adjusting for covariates including weather conditions on the previous weekend. RESULTS: On summer weekends, 73% of children spent longer than 15 minutes outdoors in peak ultraviolet radiation periods. Of these, 64% were protected by a hat and 58% by sun-protection factor 15 or higher sunscreen, 32% stayed under shade, and 18% wore three-quarter or long-sleeved tops. Overall, 8% of children had sunburn. Parental attitudes were typically supportive of children's sun protection. Parental use of hats (odds ratio [OR] 3.1; 95% confidence interval [CI] 1.6-6.2), shade (OR 9.6; 95% CI 4.4-20.8), sunscreen (OR 12.6; 95% CI 5.2-30.4), longer leg cover (OR 10.3; 95% CI 4.4-24.0), and two or more protective behaviors (OR 5.7; 95% CI 2.8-11.9) increased the odds of their children practicing these behaviors, as did some parental attitudes. LIMITATIONS: We relied on cross-sectional parent reports. CONCLUSION: Although children's sun protection was favorable, there was room for improvement. Health promotion to improve sun-protection practices in adults may benefit children's sun-safe behaviors.

The effectiveness of a community playground intervention.

This study assessed whether an upgrade of playgrounds in a community was associated with changes in the physical activity of local children. The study used a natural experiment design with a local authority project to upgrade two community playgrounds as the intervention and a matched control community. Children's physical activity was measured by an Actigraph GT1M accelerometer worn for 8 days, enabling up to 6 days of data to be analyzed. A self-administered parent/guardian questionnaire was used to collect additional data, including perceptions of the neighborhood, school-travel modes, days involved in extracurricular activities, ethnicity, caregiver age, caregiver sex, household vehicle access, and household income. At baseline, 184 children (5-10 years old) participated. Of these, 156 completed the 1-year follow-up assessment (20% lost to follow-up). There was statistically significant evidence that change in mean total daily physical activity was associated with on an interaction between participant's body mass index (BMI) z-score and her or his community of residence (p = 0.006), with the intervention being associated with higher levels of activity for children with lower BMIs but lower levels for children with higher BMIs. Physical activity is not the only focus of local authority playground provision as playgrounds also have benefits for social development and fundamental movement skills. However, making sure that physical activity is always included in the design rationale and that playgrounds are designed to encourage and sustain physical activity could be a useful population health intervention. The effects of such interventions on different subgroups are of importance, especially if the effects differ over levels of BMI.

Primary school sun protection policies and practices 4 years after baseline--a follow-up study.

Before the 2005 launch of the New Zealand SunSmart Schools Accreditation Programme (SSAP), 242 randomly sampled primary schools completed a mail survey about sun protection policies, practices, curriculum and environment. A 2009 follow-up included 189 (78%) and their mean Total Accreditation Score (TAS = total SSAP requirements met, range 0-12), increased by 0.8 (95% CI 0.5-1.2, P < 0.001) from 7.8 (95% CI 7.4-8.1) to 8.6 (95% CI 8.3-8.9) with evidence changes differed between regions (P = 0.024). The 2009 mean TAS varied by region (range 7.9-9.4, unadjusted P = 0.004, adjusted P = 0.013) with no clear pattern, but likely resource allocation association. TAS of schools acknowledging input from Health Promoting Schools demonstrated a tendency towards being statistically significantly higher by 0.5 (95% CI -0.1 to 1.1, P = 0.082), but statistically significantly higher by 1.1 (95% CI 0.5-1.7, P < 0.001) for schools acknowledging Cancer Society input. Lowest attainment was for the clothing (43%), shade (52%) and curriculum (55%) criteria. Key perceived barriers were cost, particularly of shade and limited support by parents and others. Schools which had not applied for accreditation identified lack of programme awareness and 'other priorities' as barriers; further information, better resourcing and training assistance as key needs. Observed positive change justifies increased support to consolidate gains and achieve sustainable universality.

"Prescribing sunshine": a national, cross-sectional survey of 1,089 New Zealand general practitioners regarding their sun exposure and vitamin D perceptions, and advice provided to patients.

BACKGROUND: The health effects of ultraviolet radiation vary according to wavelength, timing and pattern of exposure, personal characteristics and practices. Negative effects include skin cancers, eye diseases and immune suppression; positive effects primarily relate to endogenous vitamin D production which protects against bone disease. Drafting comprehensive guidelines regarding appropriate sun protective behaviours and vitamin D sufficiency is challenging. Advice given by general practitioners is potentially influential because they are widely respected. METHODS: A survey instrument was developed, pre-tested and provided to practising GP's, either by on-line link or mailed, reply paid hard-copy. Odds ratios, differences in means, or ratios of geometric means from regression models are reported for potential predictor variables with 95% confidence intervals. RESULTS: Data (demographic, training, practicing, information accessing, confidence in vitamin D knowledge) suitable for analysis were obtained from 1,089 GPs (32% participation). Many (43%) were 'not at all confident' about their vitamin D knowledge. Recent information led 29% to recommend less sun protection during winter months and 10% less all year. Confidence was positively associated with non-'Western' medical training, information sources read and practising in a metropolitan centre with a medical school. Reading the Melanoma Clinical Practice Guidelines was associated with lower estimates of the amount of summer sun exposure required to obtain adequate vitamin D. Increasing years in practice was negatively associated with provision of recommended advice about summer and winter sun protection. Greater concern about vitamin D than skin cancer was expressed by females and those in practice longer. CONCLUSIONS: Concern about the potentially negative impact of skin cancer prevention on vitamin D status may undermine appropriate sun protective recommendations. Reading some educational resources was associated with confidence about vitamin D knowledge and a perception that significantly less summer sun exposure was required for those with high sun sensitivity to achieve adequate vitamin D, suggesting a potentially positive impact of such resources. Education could be targeted towards groups least likely to promote existing recommendations. Authoritative guidelines about vitamin D and sun protection would be a valued resource among GPs. Study findings are potentially valuable to help guide public policy and target interventions.

Inadequate sun protection practices lead to sunburn among New Zealanders.

A Photoaging Intervention Delivered to Adolescents in Secondary Schools: A Feasibility Study.

Excessive exposure to ultraviolet radiation during adolescence can have a lasting effect on long-term skin cancer risk. Skin cancer prevention interventions for adolescents have been less commonly investigated than those for children and adults. The study objectives were to develop and evaluate the feasibility of a secondary school-based appearance focused intervention, including the development and testing of protocols and instruments, as a resource module that could be efficiently integrated into the secondary school science curriculum. This longitudinal study was conducted with a convenience sample of 38 13-14 year-old students attending one New Zealand (NZ) urban secondary school. The recruitment rate was excellent with only one student not participating because of parental concern. In terms of the implementation practicality, the intervention, as it stands, was extremely resource intensive, involving four research staff to deliver. This will not work if delivered in a classroom setting by a single teacher. However, the intervention was well received by students, so it shows promise if a less resource intensive version could be produced. The acceptability of the intervention with the students was good with the majority (61%) having no suggestions for improvements. Suggested improvements were minor and could be easily addressed.

Political activity for physical activity: health advocacy for active transport.

Effective health advocacy is a priority for efforts to increase population participation in physical activity. Local councils are an important audience for this advocacy. The aim of the current study was to describe features of advocacy for active transport via submissions to city council annual plans in New Zealand, and the impact of an information sheet to encourage the health sector to be involved in this process. Written submissions to city council's annual consultation process were requested for 16 city councils over the period of three years (2007/08, 2008/09, and 2009/10). Submissions were reviewed and categories of responses were created. An advocacy information sheet encouraging health sector participation and summarising some of the evidence-base related to physical activity, active transport and health was released just prior to the 2009/10 submission time. Over the period of the study, city councils received 47,392 submissions, 17% of which were related to active transport. Most submissions came from city residents, with a small proportion (2%) from the health sector. The largest category of submissions was in support of pedestrian and cycling infrastructure, design and maintenance of facilities and additional features to support use of these transport modes. Health arguments featured prominently in justifications for active transport initiatives, including concerns about injury risk, obesity, physical inactivity, personal safety and facilities for people with disabilities. There was evidence that the information sheet was utilised by some health sector submitters (12.5%), providing tentative support for initiatives of this nature. In conclusion, the study provides novel information about the current nature of health advocacy for active transport and informs future advocacy efforts about areas for emphasis, such as health benefits of active transport, and potential alliances with other sectors such as environmental sustainability, transport and urban planning and local communities.

Effectiveness of Sun Protection Interventions Delivered to Adolescents in a Secondary School Setting: A Systematic Review.

AIM: The aim of this systematic review is to summarise the evidence of the effectiveness of interventions targeted to adolescents (13 to 18 years inclusive) and delivered in a secondary school setting with the purpose of improving sun protection behaviour, reducing ultraviolet radiation (UVR) exposure, and/or improving physiological outcomes related to UVR exposure (such as erythema or naevi development). METHODS: Peer-reviewed journal articles were identified from seven database searches (Cochrane, Embase, CINAHL, Scopus, Medline, PsycInfo, and Web of Science) to January 2020, forward citation searches of relevant articles, and monitoring of WHO INTERSUN UVR list server for recent publications. Relevant articles were collected and critically analysed using the Effective Public Health Practice framework. Two reviewers independently reviewed, and when deemed eligible, extracted data and performed quality appraisals for each study. RESULTS: Thirteen studies met the criteria for inclusion in the review. There were no studies that met a "strong" quality rating, five received a "moderate" quality rating, and eight studies a "weak" quality rating. Three of those with a moderate rating found evidence for effectiveness. The most promising interventions overall (including the pilot/uncontrolled studies) were those that moved beyond a pure health education approach and used innovative approaches such as the provision of shade, or use of technology (e.g., appearance-based apps or real-time ultraviolet index (UVI) monitors). CONCLUSIONS: There is a lack of high-quality published studies investigating the interventions delivered in a secondary school setting to protect students from UVR. The evidence could be strengthened if researchers used consistent, standardised outcome measures for sun protection exposure and behaviour. Other factors limiting the strength of evidence were short follow-up times (largely less than 6 months) and/or nonrobust study design.

Erythemal ultraviolet radiation exposure of high school rowers in Aotearoa/New Zealand.

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