Solar UV Measured under Built-Shade in Public Parks: Findings from a Randomized Trial in Denver and Melbourne.

Reducing exposure to ultraviolet radiation (UV) is crucial for preventing UV-induced diseases of the skin and eyes. Shade may offer significant protection from UV. More empirical research to quantify the UV protection offered from built shade is needed to guide disease prevention practices and confidence in investment in shade.

Effect of an interactive educational activity using handheld ultraviolet radiation dosimeters on sun protection knowledge among Australian primary school students.

Ultraviolet radiation (UV) is the main cause of skin cancer, and children are a priority group for reducing UV exposure. We evaluated whether an interactive educational activity using handheld dosimeters improved UV-related knowledge among primary (elementary) school students. We conducted an uncontrolled before-after study among 427 students in grades 3-6 (ages 8-12 years) at five schools in the Greater Sydney region, Australia.

Impact of personal genomic risk information on melanoma prevention behaviors and psychological outcomes: a randomized controlled trial.

Purpose: We evaluated the impact of personal melanoma genomic risk information on sun-related behaviors and psychological outcomes.

Methods: In this parallel group, open, randomized controlled trial, 1,025 Australians of European ancestry without melanoma and aged 18-69 years were recruited via the Medicare database (3% consent). Participants were randomized to the intervention (n = 513; saliva sample for genetic testing, personalized melanoma risk booklet based on a 40-variant polygenic risk score, telephone-based genetic counseling, educational booklet) or control (n = 512; educational booklet).

Prevalence and Correlates of Observed Sun Protection Behaviors Across Different Public Outdoor Settings in Melbourne, Australia.

Skin cancer prevention efforts in Australia have increasingly incorporated a focus on protection during incidental sun exposure. This complements the long-present messages promoting protection in high-risk settings and avoidance of acute intense bouts of sun exposure. Data from two waves of a cross-sectional direct observational survey was used to assess the prevalence and correlates of = 12,083 adolescents' and adults' sun protection behavior (arm and leg cover, hat, sunglasses, and shade cover).

School-based interventions to improve sun-safe knowledge, attitudes and behaviors in childhood and adolescence: A systematic review.

Ultraviolet radiation exposure is the leading cause of skin cancer, and childhood and adolescence is a particularly susceptible life period for exposure. This systematic review assessed whether interventions in elementary and secondary school settings reduced sun exposure, sunburns, and development of melanocytic nevi, and improved sun-safe knowledge, attitudes and sun protection behaviors in childhood and adolescence. A systematic search up to June 2020 of MEDLINE, Embase, CINAHL, Cochrane and ProQuest databases was undertaken, for studies conducted among students in an elementary or secondary school setting that compared an intervention group with a pre-intervention or separate control group.

Prevalence of skin examination behaviours among Australians over time.

Background: We aimed to examine the prevalence and correlates of opportunistic skin check behaviours among Australians and whether changes over time might explain increasing underlying rates of melanoma in situ.

Methods: The National Sun Protection Survey involved periodic telephone-based cross-sectional surveys during summer since 2003. Skin checks by a doctor in the past 12 months was asked in four summers over 2006-2017, and responses from 23,374 Australians aged 12-69 years were analysed.

Examining Health-Related Effects of Refurbishment to Parks in a Lower Socioeconomic Area: The ShadePlus Natural Experiment.

Degraded parks in disadvantaged areas are underutilized for recreation, which may impact long-term health. Using a natural experiment, we examined the effects of local government refurbishments to parks (n = 3 intervention; n = 3 comparison) in low socioeconomic areas (LSEA) of Melbourne on park use, health behavior, social engagement and psychological well-being. Amenities promoting physical activity and sun protection included walking paths, playground equipment and built shade.

Sun-protective clothing and shade use in public outdoor leisure settings from 1992 to 2019: Results from cross-sectional observational surveys in Melbourne, Australia.

Skin cancer presents a significant public health burden in Australia. The present study aimed to supplement population-based estimates of sun protection behaviour by examining setting-specific trends in directly observed sun protection in public outdoor leisure settings. Repeated cross-sectional observational surveys of adolescents and adults were conducted on summer weekends between 11 am and 3 pm from 1992 to 2002, 2006 to 2012, and 2018 to 2019 (N = 44,979) at pools/beaches and parks/gardens within 25 km of the centre of Melbourne, Victoria.

Concerns about vitamin D and sun exposure behaviour among Australians.

Issues Addressed: Australians' concerns about vitamin D and influence on sun protection were last quantified a decade ago in Queensland amidst media attention on emerging evidence of non-skeletal benefits of vitamin D. Meanwhile these circumstances persist and impact is worth assessing.

Methods: Measures of concern about vitamin D were included in three recent population-based cross-sectional surveys of Australians' sun-related behaviours during summer months (2010-2011, 2013-2014 and 2016-2017).

Implementation of the SunSmart program and population sun protection behaviour in Melbourne, Australia: Results from cross-sectional summer surveys from 1987 to 2017.

Background: Australia has one of the highest skin cancer rates in the world. 'SunSmart' is a multi-component, internationally recognised community-wide skin cancer prevention program implemented in Melbourne, Australia, since summer 1988-1989. Following recent reductions in melanoma rates among younger Australian cohorts, the extent of behaviour change and the potential contribution of prevention programs to this decline in melanoma rates are of interest.

Not part of my routine: a qualitative study of use and understanding of UV forecast information and the SunSmart app.

Background: The Ultraviolet (UV) Index provides a reliable means of monitoring the strength of UV radiation at the Earth's surface, which can be used to indicate the potential for skin damage. This qualitative study aims to examine public understanding of the UV Index among Australians who routinely use UV forecast information as well as those who do not.

Methods: Recent use of the SunSmart app (a popular mobile and tablet app that provides UV forecast information) served as a proxy for use of UV forecast information.

Teacher perceptions of sun protection practices in the secondary school setting: Barriers, enablers and recommendations for future.

Objective: This qualitative study aimed to explore sun protection barriers and enablers in secondary schools in Victoria.

Methods: Five focus groups were conducted with nominated Health or Physical Education (PE) Coordinators (or other staff representatives) from schools in metropolitan and regional Victoria. Discussions were audio-recorded, transcribed and coded thematically.

Risk attitudes and sun protection behaviour: Can behaviour be altered by using a melanoma genomic risk intervention?

Background: Exposure to ultraviolet radiation from sunlight is directly associated with melanoma skin cancer, however reducing sun-exposure can be difficult to achieve at a population level.

Methods: Using a genomic risk information behaviour change trial for melanoma prevention, we classified participants as risk-seeking, risk-neutral or risk-averse for domain-specific risk taking (DOSPERT). One-way ANOVA determined the association between socio-demographic characteristics and risk-taking score, and multivariable linear regression ascertained impact of an individual's underlying risk propensity on an objective measure of sun-exposure, standard erythemal dose (SED), at 3-months follow-up.

The melanoma genomics managing your risk study: A protocol for a randomized controlled trial evaluating the impact of personal genomic risk information on skin cancer prevention behaviors.

Background: Reducing ultraviolet radiation (UV) exposure and improving early detection may reduce melanoma incidence, mortality and health system costs. This study aims to evaluate the efficacy and cost-effectiveness of providing information on personal genomic risk of melanoma in reducing UV exposure at 12 months, according to low and high traditional risk.

Methods: In this randomized controlled trial, participants (target sample = 892) will be recruited from the general population, and randomized (1:1 ratio, intervention versus control).

Validation of Questionnaire and Diary Measures of Time Outdoors Against an Objective Measure of Personal Ultraviolet Radiation Exposure.

Self-reported sun exposure is commonly measured using questionnaires or diaries, but there are limited data on their validity, particularly for population subgroups. This research aimed to compare self-reported sun exposure, measured as (1) habitual time outdoors over the past month on weekends and weekdays and (2) a 4-day diary measure, against objective measurement of personal ultraviolet radiation using polysulfone film dosimeters. From November 2015 to January 2016, 94 people (22-69 years and living in New South Wales, Australia) completed a questionnaire, 4-day diary and 4-day dosimeter measures of overall, weekday and weekend sun exposure.

Shade Sails and Passive Recreation in Public Parks of Melbourne and Denver: A Randomized Intervention.

Objectives: To test whether shade sails will increase the use of passive recreation areas (PRAs).

Methods: We conducted a stratified randomized pretest-posttest controlled design study in Melbourne, Australia, and Denver, Colorado, in 2010 to 2014. We randomized a sample of 144 public parks with 2 PRAs in full sun in a 1:3 ratio to treatment or control.

Skin cancer history, sun-related attitudes, behaviour and sunburn among renal transplant recipients versus general population.

Background/objectives: Renal transplant recipients (RTR) have both an excessive skin cancer incidence and a high mortality rate. In Australia RTR receive extensive public education on skin cancer and many undergo further education pre/post-transplant. This study examines whether RTR have sufficiently rigorous sun protection behaviour compared with the general population.

Rationale, design, and baseline data of a cross-national randomized trial on the effect of built shade in public parks for sun protection.

Environments can be structured to reduce solar ultraviolet radiation (UV) exposure to prevent skin cancer. A prospective randomized trial is being conducted to test whether introducing shade sails in passive recreation areas (PRAs) in public parks will increase use and decrease UV exposure in the shaded compared to unshaded PRAs. Shade effects will be compared between Melbourne, Australia and Denver, USA.

A Pilot Randomized Controlled Trial of the Feasibility, Acceptability, and Impact of Giving Information on Personalized Genomic Risk of Melanoma to the Public.

Background: Communication of personalized melanoma genomic risk information may improve melanoma prevention behaviors.

Methods: We evaluated the feasibility and acceptability of communicating personalized genomic risk of melanoma to the public and its preliminary impact on behaviors and psychosocial outcomes. One hundred eighteen people aged 22 to 69 years provided a saliva sample and were randomized to the control (nonpersonalized educational materials) or intervention (personalized booklet presenting melanoma genomic risk as absolute and relative risks and a risk category based on variants in 21 genes, telephone-based genetic counseling, and nonpersonalized educational materials).

Comparing Handheld Meters and Electronic Dosimeters for Measuring Ultraviolet Levels under Shade and in the Sun.

This study aimed to compare the validity, reliability and practicality of alternative portable methods for measuring erythemal UVR levels in passive recreation areas in public parks. UVR levels were measured for point in time comparisons between Solarmeter 6.5 handheld meters and time-stamped electronic dosimeters in a large central park in Melbourne, Australia.

Perceptions of the solarium ban in Australia: 'Fake it, don't bake it'.

Issue Addressed: The causal link between ultraviolet radiation from solarium use and skin cancer is well established. In 2012 and 2013, state governments across Australia announced plans to ban commercial solarium use from 31 December 2014. The present study examined the responses of solarium and non-solarium users to the ban on commercial solariums in Australia.

Continued Impact of SunSmart Advertising on Youth and Adults' Behaviors.

Introduction: Televised advertising campaigns play a central role in public education for skin cancer prevention in Australia. Continued impact on behavior is crucial to optimize these investments. This study examines whether exposure to increased intensity of summer campaigns in the past decade has continued to influence sun protection behaviors and to examine behavioral impact across age groups.

Maximising students' use of purpose-built shade in secondary schools: quantitative and qualitative results of a built-environment intervention.

A trial installing shade sails at secondary schools found increased students' use of newly shaded areas, but relatively low use overall. We examined site features and weather related to use of these shaded areas. Tables with seats and temperatures ≥27°C increased student use of shaded areas, presence of grass decreased use.
