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.
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.

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.
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.

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.
View Article and Find Full Text PDFAim: 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.
Aim: To assess sun protection policies and practices in New Zealand primary schools.
Methods: Principals at 1,243 schools (62% of eligible primary schools) completed a survey about school: 1) provision of personal and environmental sun protection, 2) sun protection practices.
Results: Virtually all schools (94%) had a sun protection policy/procedure about which their community was informed (96%).
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.

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.

Method: In January 2016, we conducted a national audit of businesses potentially providing sunbed services (solariums, beauty-salons, hairdressers, gyms and fitness centres) to assess the availability and cost of indoor tanning services (sunbeds and spray tanning). In addition, Trade Me©, New Zealand's largest auction site for second-hand goods, was monitored for one year to determine whether ex-commercial sunbeds were being sold in the domestic market.
There is uncertainty about the amount of sun exposure required to increase low blood 25-hydroxyvitamin D (25(OH)D) levels, a possible disease risk factor. The study aimed to quantify the association between sun exposure and serum 25(OH)D concentrations in a multiethnic community sample (n=502) living in Auckland (37°S) and Dunedin (46°S), New Zealand, aged 18-85 years. They wore electronic ultraviolet dosimeters between March and November (autumn, winter and spring) for 8 weeks to record their sun exposure.

Objective: To observe the sun-protective practices of students and staff and related aspects of the physical environment at secondary school athletics days.
Methods: This observational study of 1,225 students and 215 adult supervisors examined the use of sun-protective items (hats, clothing coverage, sunglasses), sunscreen provision and shade.
Results: Sun-protective behaviour was poor with only 3% of students and 25% of adult supervisors wearing a sun-protective hat.
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.

Knowledge and understanding of the UVI has been evaluated among adult populations but not among school students.
Objectives: To draw on previously unpublished data from two school-based studies, one in New Zealand (NZ) and the other in South Africa (SA), to investigate and compare students' knowledge of the UVI and, where possible, report their understanding of UVI.
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.
There has been an increased interest in the role of vitamin D in depression; however, there have been few studies conducted in younger population groups. Our aim was to investigate the association between vitamin D status and depressive symptoms in a non-clinical young adult sample living in Dunedin, New Zealand. A cross-sectional sample of 615 young adults completed a questionnaire including demographics and the Centre for Epidemiological Studies Depression Scale (CES-D).

Background: Skin pigmentation is a key factor for ultraviolet radiation exposure-related cancers and can make a significant contribution to the patterns of other diseases. For surveys, and to appropriately target cancer control activities, valid and reliable measures of skin color are required.
Methods: Validity and reliability of the Munsell Soil Color Charts were investigated for skin color assessment.
Socioecological theory suggests that there are a range of influences that affect the physical activity levels of children, including parents' perceptions of the neighborhood. A questionnaire instrument to quantify parental neighborhood perceptions was developed for the Location of Children's Activity in Their Environment study as a potential predictor of children's physical activity. A literature review revealed a lack of appropriate instruments, many containing highly localized items.
