Stevens HR, Graham PL, Beggs PJ, Ossola A. Associations between violent crime inside and outside, air temperature, urban heat island magnitude and urban green space. INTERNATIONAL JOURNAL OF BIOMETEOROLOGY 2024; 68:661-673. [PMID: 38189988 DOI: 10.1007/s00484-023-02613-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/09/2021] [Revised: 12/18/2023] [Accepted: 12/19/2023] [Indexed: 01/09/2024]
Abstract
There are more incidents of violence in summer and on hot days, a trend likely to be exacerbated by climate change. Urban areas experience additional temperature modulation due to the urban form, however, to date, no studies have considered the effect of the urban heat island (UHI) or green space with respect to the temperature-violence relationship. This study modelled the relationship between the number of daily violent crime incidents that occurred inside or outside between July 2013 and June 2018, and the average surface UHI or percentage greencover (including grasses, shrubs and trees) within each local government area in Greater Sydney, Australia. Panelised negative binomial time series regression models indicated that the violent crime rate was associated with higher surface UHI for crimes committed outside (p = 0.006) but not inside (p = 0.072). Greater percentage of all vegetation was associated with significantly lower rates of violent crime committed outside (p = 0.011) but was not associated with violent crimes committed inside (p = 0.430). More socio-economic disadvantage was associated with higher rates of violent crime committed inside (p = 0.002) but not outside (p = 0.145). Greater temperature was non-linearly associated with higher rates of violent crime committed both inside and outside (p < 0.001). The findings of this study are important because both violence and heat exposure are critical health issues and will be stressed by urbanisation and climate change. The expansion of green space and/or reduction in UHI may mitigate these effects.

Abstract
BACKGROUND The number of skin cancer cases and related deaths continues to increase worldwide, including in Portugal. The lack of efficient health care leaves the southern Portuguese population at risk of presenting skin lesions at later stages. An initiative for skin cancer screening and medical care follow-up was created by the nonprofit organization Liga Portuguesa Contra o Cancro - Núcleo Regional do Sul (LPCC-NRS). METHODS Information was gathered from 4,398 participants in several Southern Portugal regions, from January 2021 to July 2022. Descriptive and lesion risk statistical analyses were applied. RESULTS Participants' characteristics were described, and risk assessment was performed differentially between premalignant (n = 577) and malignant lesions (n = 176). The main risk factor for both was male gender. From the described suspicious malignant lesions, 31.8% were confirmed (n = 56), among which there were 43 basal cell carcinomas (BCC), 9 cutaneous melanomas (CM), and 4 squamous cell carcinomas (SCC). CONCLUSIONS Data analysis pointed to a need for improved participant recruitment, especially of male participants, and health literacy assessment in future screenings.

Abstract
Skin cancer risk increases with age and prolonged exposure to ultraviolet radiation (UVR), particularly in rural geographical locations and for individuals with light skin complexions. However, the impact of UVR-induced skin cancer risk and sun-protective behaviors in rural older populations working outdoors has yet to be explored. A scoping review was conducted to fill this gap, with 12 articles meeting the inclusion criteria of aged 50 years and older among rural outdoor workers. Skin cancer risk factors, prevention strategies, and barriers to sun-protective behaviors were summarized for each study. The scoping review addressed some key differences in age-related effects of UVR among rural older outdoor workers compared to studies among adults in general. Findings have policy and research implications that highlight the need to design feasible preventive strategies to reduce rural disparities in cancer care and enhance access to preventive services for this high-risk population.

Abstract
AIMS We aimed to estimate the incidence and mortality of uveal melanoma (UM) in Australia from 1982 to 2014. METHODS Deidentified unit data for all cases of ocular melanoma were extracted from the Australian Cancer Database from 1 January 1982 to 31 December 2014. UM cases were extracted and trends in incidence and disease-specific mortality were calculated. Incidence rates were age-standardised against the 2001 Australian Standard Population. Mortality was assessed using Cox regression. RESULTS From 1982 to 2014, there were 5087 cases of ocular melanoma in Australia, of which 4617 were classified as UM. The average age-standardised incidence rate of UM was 7.6 (95% CI 7.3 to 7.9) per million. There was an increase (p=0.0502) in the incidence of UM from 1982 to 1993 with an annual percent change (APC) of +2.5%, followed by a significant decrease in the incidence of UM from 1993 to 2014 (APC -1.2%). The average 5-year survival from 1982 to 2011 did not significantly change from an average of 81%, with an average APC (AAPC) of +0.1%. A multivariate Cox regression revealed that residence in Western Australia (p=0.001) or Tasmania (p=0.05), age ≥60 years (p<0.001) and histological classification as mixed (p<0.001) or epithelioid cells (p<0.001) were significantly associated with reduced survival. CONCLUSION In conclusion, we found that the incidence of UM peaked in the 1990s. Although treatment for primary UM has improved in the last 30 years, overall survival did not change significantly in the last 30 years.

Sex and Gender Differences in Occupational Hazard Exposures: a Scoping Review of the Recent Literature. Curr Environ Health Rep 2021; 8:267-280. [PMID: 34839446 PMCID: PMC8627292 DOI: 10.1007/s40572-021-00330-8] [Citation(s) in RCA: 33] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 10/28/2021] [Indexed: 01/08/2023]
Abstract
PURPOSE OF REVIEW Comparative research on sex and/or gender differences in occupational hazard exposures is necessary for effective work injury and illness prevention strategies. This scoping review summarizes the peer-reviewed literature from 2009 to 2019 on exposure differences to occupational hazards between men and women, across occupations, and within the same occupation. RECENT FINDINGS Fifty-eight studies retrieved from eight databases met our inclusion criteria. Of these, 30 studies were found on physical hazards, 38 studies on psychological/psychosocial hazards, 5 studies on biological hazards, and 17 studies on chemical hazards. The majority of studies reported that men were exposed to noise, vibration, medical radiation, physically demanding work, solar radiation, falls, biomechanical risks, chemical hazards, and blood contamination; while women were exposed to wet work, bullying and discrimination, work stress, and biological agents. Within the same occupations, men were more likely to be exposed to physical hazards, with the exception of women in health care occupations and exposure to prolonged standing. Women compared to men in the same occupations were more likely to experience harassment, while men compared to women in the same occupations reported higher work stress. Men reported more exposure to hazardous chemicals in the same occupations as women. The review suggests that men and women have different exposures to occupational hazards and that these differences are not solely due to a gendered distribution of the labor force by occupation. Findings may inform prevention efforts seeking to reduce gender inequalities in occupational health. Future research is needed to explain the reasons for sex/gender inequality differences in exposures within the same occupation.

Abstract
Myopia (near-sightedness) is an important public health issue. Spending more time outdoors can prevent myopia but the long-term association between this exposure and myopia has not been well characterised. We investigated the relationship between time spent outdoors in childhood, adolescence and young adulthood and risk of myopia in young adulthood. The Kidskin Young Adult Myopia Study (KYAMS) was a follow-up of the Kidskin Study, a sun exposure-intervention study of 1776 children aged 6–12 years. Myopia status was assessed in 303 (17.6%) KYAMS participants (aged 25–30 years) and several subjective and objective measures of time spent outdoors were collected in childhood (8–12 years) and adulthood. Index measures of total, childhood and recent time spent outdoors were developed using confirmatory factor analysis. Logistic regression was used to assess the association between a 0.1-unit change in the time outdoor indices and risk of myopia after adjusting for sex, education, outdoor occupation, parental myopia, parental education, ancestry and Kidskin Study intervention group. Spending more time outdoors during childhood was associated with reduced risk of myopia in young adulthood (multivariable odds ratio [OR] 0.82, 95% confidence interval [CI] 0.69, 0.98). Spending more time outdoors in later adolescence and young adulthood was associated with reduced risk of late-onset myopia (≥ 15 years of age, multivariable OR 0.79, 95% CI 0.64, 0.98). Spending more time outdoors in both childhood and adolescence was associated with less myopia in young adulthood.

Abstract
OBJECTIVE To assess the prevalence and determinants of sun protection behaviours among outdoors workers at work and leisure in Alberta, Canada. METHODS We collected outdoor workers' demographics, skin cancer risk factors, job information, and sun habits at work and leisure using self-completed questionnaires. For both settings, we compared use of specific behaviours and modelled determinants of sun protection behaviour scores. RESULTS At work, wearing a sleeved shirt (81% often/always) and hat (73%) were most prevalent, while seeking shade (12%) and applying sunscreen (36%) were least prevalent. Workers had higher sun protection scores at work than leisure. Hours spent outdoors was a strong determinant for both models. Additional leisure model predictors were eye colour, sex, skin type, and job group. CONCLUSIONS Differences in behaviours across settings were observed and should be considered when developing solar UVR exposure reduction initiatives.

Abstract
OBJECTIVES Workers can be exposed to a range of different carcinogenic agents in the workplace. However, previous studies have often focused on prevalence of exposure to a single carcinogen, resulting in substantial knowledge gaps regarding the extent of multiple exposures in the workplace. This study aims to investigate the current prevalence of occupational exposure to multiple carcinogens among exposed workers in Australia. METHODS The data for this study come from the Australian Work Exposures Study, a nationwide cross-sectional telephone survey of Australian workers aged between 18 and 65. Information was collected about the respondents' current employment and numerous demographic factors using a web-based application (Occupational Integrated Database Exposure Assessment System) to conduct the interview, with predefined algorithms used to automatically assign exposures to carcinogens based on the respondents' job tasks. RESULTS The majority (81%) of exposed respondents were assessed as being probably exposed to more than one carcinogen, and 26% reported exposure to five or more carcinogens. We found that after adjusting for occupation, exposure to multiple carcinogens was more likely among male respondents, while older workers (aged between 55 and 65) were less likely to be exposed to multiple carcinogens. CONCLUSIONS This study provides information on the prevalence of exposure to multiple carcinogens in the general population that has not previously been reported. This information could be useful for the intervention and control of occupational exposures to the prioritised carcinogens identified in this study.

Abstract
BACKGROUND The Slip! Slop! Slap! Sunsmart safety campaign was an Australian initiative implemented in the 1980s. To assess this campaign's effect on pterygium, we examined the rate of pterygium surgery across Australia and described the prevalence and associations of pterygium in Perth, Australia's sunniest capital city. METHODS The rate of pterygium surgery was examined using Australian Medicare data. A cross-sectional analysis of the Generation 1 (Gen1) cohort of the Raine Study was performed to investigate the prevalence of pterygium in Perth. We investigated the association between pterygium and conjunctival ultraviolet autofluorescence (CUVAF) area, an objective biomarker of sun exposure, and demographics and health variables derived from a detailed questionnaire. RESULTS Between 1994 and 2017, the rate of Medicare funded pterygium surgery in Western Australia fell 11%, well below the national average decline of 47%. Of the 1049 Gen1 Raine Study participants, 994 (571 females; mean age 56.7 years, range = 40.9-81.7) were included in the analysis. The lifetime prevalence of pterygium was 8.4% (n = 83). A higher prevalence of pterygium was associated with outdoor occupation (p-trend = 0.007), male sex (p-trend 0.01) and increasing CUVAF area (p-value <0.001). CONCLUSIONS The effect of Australia's Slip! Slop! Slap! Sunsmart safety campaign on pterygium been mixed. Since 1994, the rate of private pterygium surgery has declined significantly in all Australian states except Western Australia. Perth, Western Australia, has the highest pterygium prevalence of any mainland-Australian cohort. Higher CUVAF area, male sex, and outdoor occupation were associated with an increased risk of pterygium.

Abstract
Background Skin cancer is the most prevalent but also most preventable cancer in Australia. Outdoor workers are at increased risk of developing skin cancer, and improvements in sun protection are needed. Sunscreen, when applied at the recommended concentration (2 mg/cm2), has been shown to block the harmful molecular effects of ultraviolet radiation in vivo. However, sunscreen is often not applied, reapplied sufficiently, or stored adequately to yield protection and reduce sunburns. Objective The primary aim of this study was to test an Internet of Things approach by deploying a smart sunscreen station to an outdoor regional mining site. Methods We deployed a smart sunscreen station and examined the key technological considerations including connectivity, security, and data management systems. Results The smart sunscreen station was deployed for 12 days at a mining workplace (Dalby, Australia). The smart sunscreen station’s electrical components remained operational during field testing, and data were received by the message queuing telemetry transport server automatically at the end of each day of field testing (12/12 days, 100% connectivity). Conclusions This study highlights that an Internet of Things technology approach can successfully measure sunscreen usage and temperature storage conditions.

Abstract
Importance Keratinocyte carcinoma (KC), also known as nonmelanoma skin cancer, is the most common malignancy after solid organ transplant. Epidemiologic data on posttransplant KC in North America are limited by a lack of KC capture in cancer and transplant registries. Objective To estimate the incidence and identify risk factors for posttransplant KC. Design, Setting, and Participants This population-based inception cohort study in Ontario, Canada, used linked administrative databases and a health insurance claims-based algorithm. Participants were adult recipients of a first kidney, liver, heart, or lung transplant from January 1, 1994, to December 31, 2012. The cohort (n = 10 198) was followed up to December 31, 2013. Data were analyzed from May 31, 2016, to April 21, 2017. Exposures Solid organ transplant with functioning graft. Main Outcomes and Measures Age- and sex-adjusted standardized incidence ratio for KC in the transplant cohort was compared with that in the general population. Cumulative incidence of posttransplant KC was estimated using cumulative incidence functions, accounting for the competing risks of death or kidney graft loss. The association between KC and patient-, transplant-, and health services-related factors was evaluated with a multivariable cause-specific hazards model. Results A total of 10 198 transplant recipients were included in the study. The median (interquartile range [IQR]) age at transplant was 51 (41-59) years, with most recipients being male (6608 [64.8%]) and white (5964 [58.5%]). Posttransplant KC was diagnosed in 1690 patients (16.6%) after a median (IQR) of 3.96 (1.94-7.09) years, with an incidence rate of 2.63 per 100 patient-years (95% CI, 2.51-2.76). The rate of KC was significantly higher after transplant compared with the general population (standardized incidence ratio, 6.61; 95% CI, 6.31-6.93). The highest 10-year cumulative incidence was in the subsets of patients with a history of pretransplant skin cancer (66.5%), older than 50 years at transplant (27.5% for 51-65 years; 40.5% for >65 years), and of the white race (24.1%). The strongest independent risk factors for KC included older age at transplant (adjusted hazard ratio [aHR], 9.27; 95% CI, 7.08-12.14 for >65 years vs 18-35 years), white vs black race (aHR, 8.50; 95% CI, 4.03-17.91), pretransplant invasive skin cancer (aHR, 4.30; 95% CI, 3.72-4.98), and posttransplant precancerous skin lesions (aHR, 4.32; 95% CI, 3.77-4.95). Conclusions and Relevance The incidence of KC appeared to be substantially increased after transplant, particularly in patients who were older at transplant, were white, and had a history of cancerous or precancerous skin tumors; intensified skin cancer screening, education, and early use of chemopreventive interventions may be warranted for these high-risk patient subsets.

Ziehfreund S, Schuster B, Zink A. Primary prevention of keratinocyte carcinoma among outdoor workers, the general population and medical professionals: a systematic review updated for 2019. J Eur Acad Dermatol Venereol 2019; 33:1477-1495. [PMID: 30801774 DOI: 10.1111/jdv.15525] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2018] [Accepted: 01/29/2019] [Indexed: 02/07/2023]
Abstract
Worldwide 2-3 million cases of keratinocyte carcinoma (KC) are diagnosed annually. Sun-related knowledge is essential for adequate protection against solar ultraviolet radiation (UVR), the main risk factor for KC. The goal was (i) to provide an updated overview of primary prevention against KC including skin cancer-related knowledge, attitudes and sun protection behaviour (SPB) of outdoor workers, the general population and medical professionals as well as (ii) to evaluate the effectiveness and acceptability of sun protection programmes. We conducted a systematic review of articles indexed for MEDLINE on PubMed using selected MeSH terms and keywords related to the studied topic as well as an extensive hand search of publications between 1 January 2012 and 31 December 2018. We identified 51 relevant cross-sectional studies and 22 interventional studies. Sun-related knowledge and attitude showed substantial differences with some alarming results, including people who had not even heard about skin cancer before. Reported SPB varied enormously between the included studies, with none of the studies providing an overall sufficient SPB in their examined sun protection measures. However, sun protection programmes using new technologies seem to have great potential to increase sun-related knowledge and SPB. In countries worldwide, particularly in those where KC is not yet a public health issue, UVR protection should be promoted by healthcare institutions and authorities, politicians, cancer foundations and dermatologists to increase awareness as well as SPB and to decrease the worldwide burden of KC.

Abstract
PURPOSE To describe the prevalence of visually significant cataract in Indigenous and non-Indigenous Australians. METHODS A total of 3098 non-Indigenous Australians aged 50 years and over and 1738 Indigenous Australians aged 40 years and over, residing in 30 randomly selected Australian sites, were examined as part of the population-based National Eye Health Survey (NEHS). For those with visual acuity worse than 6/12, photos of the anterior and posterior segment were taken with a nonmydriatic fundus camera and assessed for cataract. Visually significant cataract was assigned in eyes with best-corrected visual acuity worse than 6/12 and cataract that was determined to be the primary cause of vision loss in that eye. RESULTS In total, 99.2% (4797/4836) participants had complete data for visual acuity and cataract assessment. The overall weighted prevalence of visually significant cataract was 2.7% (95% CI: 2.0, 3.5) in non-Indigenous Australians and 4.3% (95% CI: 3.1, 5.9) among Indigenous Australians. After adjusting for age and gender, the odds of visually significant cataract were almost three times higher among Indigenous participants compared to non-Indigenous participants (adjusted odds ratio (OR) 2.95, 95% CI: 2.03, 4.29). Only 54.8% of non-Indigenous Australians and 38.9% of Indigenous Australians with visually significant cataract self-reported a known history of cataract. CONCLUSIONS Our results suggest that continued efforts are required to build sustainable cataract surgery services within Indigenous communities. Furthermore, given the significant ageing of the Australian population, maintaining high cataract surgery rates amongst the non-Indigenous population is critical to reduce cataract-related vision loss.

Low 25-Hydroxyvitamin D Concentration Is Not Associated With Refractive Error in Middle-Aged and Older Western Australian Adults. Transl Vis Sci Technol 2019; 8:13. [PMID: 30697464 PMCID: PMC6348994 DOI: 10.1167/tvst.8.1.13] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2018] [Accepted: 11/15/2018] [Indexed: 12/29/2022] Open
Abstract
Purpose To investigate the association between serum 25-hydroxyvitamin D (25[OH]D) concentration and refractive error in a community-based cohort of adults aged 46 to 69 years. Methods Residents of the City of Busselton in Western Australia born between 1946 and 1964 were invited to participate. Participants underwent cycloplegic autorefraction and completed questionnaires on education, occupational sun exposure, and physical activity. Blood samples were collected and serum frozen at −80°C. Serum 25[OH]D concentration was measured by immunoassay. Data on 25[OH]D were deseasonalized and multivariate models built to analyze the association between 25[OH]D concentration and spherical equivalent and myopia, defined as spherical equivalent <−0.50 D. Results After exclusions, data were available for 4112 participants. Serum 25[OH]D concentration was not associated with spherical equivalent or myopia after adjustment for confounding factors (β = −0.01, 95% confidence interval [CI]: −0.03 to −0.008, P = 0.25, and odds ratio = 1.02, 95% CI: 0.99 to 1.05, P = 0.12, respectively). When participants were classified into 25[OH]D groups of lower (<50 nmol/L), medium (≥50 to <75 nmol/L), and upper (≥75 nmol/L), the upper group had slightly greater myopic refractive error than the medium group (P = 0.02) but not the lower group, after adjustment for confounders. Conclusions There was no substantial association between 25[OH]D levels and spherical equivalent or odds of myopia in this study. The association previously noted between low serum 25[OH]D level and myopia in younger Western Australians is not evident in later adulthood. Translational Relevance This study provides further evidence suggesting that vitamin D levels are unrelated to myopia risk in adults and thus not a suitable target for myopia intervention.

Abstract
The exposure of outdoor car guards to solar ultraviolet radiation (UVR), the majority with deeply pigmented skin, to solar UVR was measured for five consecutive days during early spring (September 2017) in South Africa using electronic UVR dosimeters attached to the upper arm of each participant. The exposure of the nape of the neck, forehead, nose, cheek and hand was extrapolated from the measurements. The onsite ambient solar UVR on a flat, horizontal, unshaded surface was measured concurrently. The sun-related knowledge, behavior and attitudes of the car guards were evaluated using questionnaires. Total personal daily solar UVR exposure as a percentage of the ambient solar UVR exposure was 24%. The exposure of car guards on several body sites was in excess of the occupational threshold limit value. Sleeved shirts and hats were the most commonly used sun protection measures (worn by 70% and 80%, respectively). Considering the high levels of solar UVR reported on most days throughout the year in South Africa, more studies quantifying the personal exposure of outdoor workers in both the informal and formal sectors are necessary.

Abstract
BACKGROUND UV exposure is strongly associated with the incidence of non melanoma skin cancers (NMSCs), both basal and squamous cell carcinomas. The aim of our study was to analyze risk perception, UV exposure, preventive habits, and occupation in 126 subjects affected by NMSC and 187 controls. METHODS Consecutive cases with incident NMSC were recruited in Dermatologic Unit at University of Trieste; controls were recruited in Unit of Occupational Medicine. All had a medical examination to define Fitzpatrick skin type and skin lesions, and filled a standardized questionnaire on sun exposure habits, sun protection, occupational exposures, and sunburns in adulthood and childhood. RESULTS In multivariate regression analysis, NMSC resulted significantly associated with age (OR: 1.03; 95% CI 1.01-1.05), with a positive feeling for tan (OR: 1.10; 95% CI 1.01-1.20), and sunbath numbers per year (OR: 1.02; 95% CI: 1.001-1.03). A protective effect was demonstrated for Fitzpatrick phototypes III-IV compared to I and II (OR: 0.31; 95% CI: 0.18-0.55), sunscreen use (OR: 0.35; 95% CI: 0.22-0.58), and risk perception (OR: 0.98; 95% CI: 0.97-0.99). In univariate analysis, we demonstrated an increased risk for fishermen, sailors, and lifeguards (OR: 4.3; 95% CI: 1.1-16.4); foundry and metallurgy workers (OR: 5.58; 95% CI: 1.14-27.3); and mechanics, fixers, and welders (OR: 8.2; 95% CI: 1.76-37.9). CONCLUSIONS Our study demonstrated that protective behavior must be implemented in people living in Trieste. Workers must avoid direct UV exposure and must use protective equipment. More efforts are needed to increase knowledge on this risk and to raise awareness among at-risk people.

Abstract
AIM To investigate whether pterygium is an indicator of an increased risk of cutaneous melanoma (CM). METHODS A matched-cohort study, using linked health administrative data sets to identify all hospital-treated pterygium in Western Australia (WA) between 1979 and 2014. We identified pterygium cases from hospital diagnosis and/or procedure International Classification of Diseases 9th revision (ICD-9) and 10th revision (ICD-10) codes and matched cases by age, sex and residential postcode to WA Electoral Roll controls with no known history of pterygium. Both cohorts were linked to the WA Cancer Registry and the WA Deaths Registry. RESULTS 23 625 people had pterygium treatment (64% male) in WA hospitals. The median age for pterygium diagnosis and/or treatment was 49 years (range 14-96). There were significantly more CM cases in the pterygium cohort compared with the control cohort (1083 vs 874; p<0.001). In a logistic regression analysis, there was a 24% increase in the odds of developing a CM in the pterygium cohort, compared with controls, after controlling for other predictors (OR 1.24, 95% CI 1.1 to 1.4). The incident rate ratio (IRR) of a malignant CM diagnosis was 20% greater in people who had treatment for a pterygium compared with controls (IRR 1.2, 95% CI 1.0 to 1.4). CONCLUSION The presence of a pterygium indicates a significantly increased risk of developing a CM. Eye care providers who see patients with developing pterygia should advise these patients of this increased risk and recommend regular skin surveillance.

Abstract
BACKGROUND Road transport workers (RTWs) are at high risk of exposure to several occupational carcinogens. However, there are gaps in knowledge regarding the extent and the circumstances of exposure. As a sub-study of the Australian Work Exposures Study, this study investigated the prevalence of occupational exposure in Australian RTWs. METHODS A random sample of Australian working population was invited to a telephone interview regarding their current jobs. An automated expert-assessment procedure was applied to self-reported job-related tasks using a web-based application. 162 RTWs were included in this study. RESULTS RTWs were exposed to diesel exhaust (97%), solar ultraviolet radiation (78%), environmental tobacco smoke (55%), benzene (29%), silica (15%), and asbestos (10%) at work. Besides driving on roads, vehicle maintenance-related tasks were the major source of carcinogen exposures among RTWs. DISCUSSION Most RTWs are exposed to at least one carcinogen at work. We have identified tasks where the use of control measures could potentially reduce exposures.

Abstract
BACKGROUND CAREX Canada has identified solar ultraviolet radiation (UV) as the second most prominent carcinogenic exposure in Canada, and over 75 % of Canadian outdoor workers fall within the highest exposure category. Heat stress also presents an important public health issue, particularly for outdoor workers. The most serious form of heat stress is heat stroke, which can cause irreversible damage to the heart, lungs, kidneys, and liver. Although the need for sun and heat protection has been identified, there is no Canada-wide heat and sun safety program for outdoor workers. Further, no prevention programs have addressed both skin cancer prevention and heat stress in an integrated approach. The aim of this partnered study is to evaluate whether a multi-implementation, multi-evaluation approach can help develop sustainable workplace-specific programs, policies, and procedures to increase the use of UV safety and heat protection. METHODS/DESIGN This 2-year study is a theory-driven, multi-site, non-randomized study design with a cross-case analysis of 13 workplaces across four provinces in Canada. The first phase of the study includes the development of workplace-specific programs with the support of the intensive engagement of knowledge brokers. There will be a three-points-in-time evaluation with process and impact components involving the occupational health and safety (OHS) director, management, and workers with the goal of measuring changes in workplace policies, procedures, and practices. It will use mixed methods involving semi-structured key informant interviews, focus groups, surveys, site observations, and UV dosimetry assessment. Using the findings from phase I, in phase 2, a web-based, interactive, intervention planning tool for workplaces will be developed, as will the intensive engagement of intermediaries such as industry decision-makers to link to policymakers about the importance of heat and sun safety for outdoor workers. DISCUSSION Solar UV and heat are both health and safety hazards. Using an occupational health and safety risk assessment and control framework, Sun Safety at Work Canada will support workplaces to assess their exposure risks, implement control strategies that build on their existing programs, and embed the controls into their existing occupational health and safety system.
