RESUMO
OBJECTIVE: This survey aimed to investigate exposure to welding fume in Australian workplaces and the use of protective and control measures among workers. METHODS: Data were collected via a cross-sectional online survey of workers and employers involved in welding in Australia. Survey questions focused on the determinants of exposure to welding fume, welding experience and qualifications, and use of control measures. RESULTS: There were 634 respondents to the survey across Australia of whom 577 (91%) were assessed as being exposed to welding fume, most at high levels. Welders undertook a wide range of types of welding, and higher-risk welding such as in confined and restricted spaces was common. Most workplaces did not have any form of mechanical ventilation, and use of air-supplied respiratory protection was poor even when ventilation was not used. CONCLUSION: Welders in Australia are exposed to several carcinogens, particularly welding fume, hexavalent chromium (CrVI) and nickel, and the use of control measures is sub-optimal. IMPLICATIONS FOR PUBLIC HEALTH: Higher-order controls are the best way to reduce exposure to carcinogens in the workplace. The lack of use of these controls by Australian welders is concerning and needs to be a focus of attention by regulators and companies.

ISSUES: The surrounding social and commercial context, including alcohol advertising, heavily influences alcohol consumption. Alcohol use is a major risk factor for both fatal and non-fatal drowning, particularly for young people. APPROACH: We conducted a scoping review to explore the peer-reviewed literature on the use of alcohol by young people (aged 15-34 years) in the context of aquatic environments. Five electronic academic databases were searched for English-language studies conducted in high-income countries and published in the last 15 years (since 2008). The MetaQAT framework was used to assess methodological quality of included studies. KEY FINDINGS: The review included a total of 24 studies, including those addressing the prevalence of and/or risk factors for alcohol use in aquatic environments among young people (n = 13); the epidemiology of alcohol-related unintentional drowning in young people (n = 9); and interventions to reduce alcohol-related harm around water (n = 3). Findings suggest that young people commonly consume alcohol around water, particularly young men. We found multiple influences on this behaviour, including the perception of risk, location of aquatic activity and presence of others, particularly peers. IMPLICATIONS: Understanding the literature addressing alcohol use around water among young people will assist in identifying and setting priorities for drowning prevention, including the need to mitigate the effects of alcohol advertising which promotes drinking in and around water. CONCLUSION: There is a clear imperative to address the use of alcohol by young people in aquatic environments. These findings have key implications for public health policy, advocacy and practice.

INTRODUCTION: Mounting evidence suggests that electronic cigarettes (e-cigarettes) are extensively promoted and marketed using social media, including through user-generated content and social media influencers. This study explores how e-cigarettes are being promoted on Instagram, using a case-study approach, and the extent to which Meta's Restricted Goods and Services Policy (Meta's policy) is being applied and enforced. METHODS: We identified the accounts followed by an Australian Instagram influencer who primarily posts e-cigarette-related content. The main foci of these 855 accounts were coded and 369 vaping-focused accounts were identified. These vaping-focused accounts were then further coded by two trained coders. RESULTS: All (n=369; 100.0%) of the vape content posted by these accounts was positive in sentiment. One-third of the vape accounts (n=127; 34.4%) had a shared focus, indicating that vape content may permeate into other online communities through shared interests. A total of 64 accounts (17.3%) potentially violated Meta's policy by attempting to purchase, sell, raffle or gift e-cigarette products. CONCLUSIONS: The findings of this study suggest that pro-vaping information is available and accessible on Instagram. Much of the content identified in this study promoted the purchase or gifting of e-cigarette products and potentially violates Meta's policy. Greater regulation and/or stronger enforcement of e-cigarette content on social media platforms such as Instagram is necessary to prevent the ongoing promotion of these harmful products.
RESUMO
E-cigarettes are promoted extensively on TikTok and other social media platforms. Platform policies to restrict e-cigarette promotion seem insufficient and are poorly enforced. This paper aims to understand how e-cigarettes are being promoted on TikTok and provide insights into the effectiveness of current TikTok policies. Seven popular hashtag-based keywords were used to identify TikTok accounts and associated videos related to e-cigarettes. Posts were independently coded by two trained coders. Collectively, the 264 videos received 2,470,373 views, 166,462 likes and 3426 comments. The overwhelming majority of videos (97.7%) portrayed e-cigarettes positively, and these posts received 98.7% of the total views and 98.2% of the total likes. A total of 69 posts (26.1%) clearly violated TikTok's own content policy. The findings of the current study suggest that a variety of predominantly pro-vaping content is available on TikTok. Current policies and moderation processes appear to be insufficient in restricting the spread of pro-e-cigarette content on TikTok, putting predominantly young users at potential risk of e-cigarette use.

Per- and poly-fluoroalkyl substances (PFAS) are a group of manmade compounds produced since the 1950 s and used in a range of industrial processes and consumer products. In Australia, PFAS serum concentrations have been measured in the general population since 2002. However, few studies have retrospectively measured PFAS concentrations in serum samples representative of a general population prior to 2000, none of which have been conducted in Australia. To understand the general population's exposure to PFAS prior to 2002, longitudinal PFAS serum concentration measurements are required. In the current study, we accessed 'The Busselton Health Study Data Bank' to analyse archived serum samples for PFAS. Repeat serum samples collected in 1975, 1981 and 1995 were obtained from 17 participants. Of the 35 PFAS analysed, 13 PFAS were detected in the serum samples collected in 1975. Both the detection frequency and ∑PFAS serum concentrations increased between 1975 and 1995. Median ∑PFAS serum concentration increased over 7-fold; from 3.3 ng/mL in 1975-26 ng/mL in 1995. The increase in serum concentrations reflects the global production history of these PFAS during this period in time.

Background: Exposure to welding fume is associated with adverse effects on worker health. The use of various control measures can reduce levels of exposure and the resulting health effects. However, little is known about the factors that may influence workers' use of control measures in the workplace and their perceived intervention needs. This study aimed to investigate workers' and other stakeholders' views on ways to improve the use of welding fume control measures in Australian workplaces. Methods: We conducted a series of online focus group discussions and individual interviews with participants who have some occupational involvement in welding, whether as workers, employers or industry representatives, union representatives, or regulators. A semi-structured question guide was used, and all discussions and interviews were recorded and transcribed for analysis. Results: Five focus group discussions and five individual interviews were conducted with a total of 21 participants. Three major themes emerged. The first addressed the current awareness of welding fume harms and concern about exposure; the second focussed on the current use of control measures, and barriers and facilitators to their use; and the last centred around intervention needs and the contents of a potential effective intervention. Conclusion: Improving the use of control measures to prevent exposure to welding fume requires knowledge around the barriers and facilitators of control, use, and the intervention needs of stakeholders. This study has provided such knowledge, which will facilitate the design and implementation of an intervention to reduce welding fume exposure and ultimately protect the health of workers.
RESUMO
BACKGROUND: Many cancers are caused by exposure to lifestyle, environmental, and occupational factors. Earlier studies have estimated the number of cancers occurring in a single year which are attributable to past exposures to these factors. However, there is now increasing appreciation that estimates of the future burden of cancer may be more useful for policy and prevention. We aimed to calculate the future number of cancers expected to arise as a result of exposure to 23 modifiable risk factors. METHODS: We used the future excess fraction (FEF) method to estimate the lifetime burden of cancer (2016-2098) among Australian adults who were exposed to modifiable lifestyle, environmental, and occupational risk factors in 2016. Calculations were conducted for 26 cancer sites and 78 cancer-risk factor pairings. RESULTS: The cohort of 18.8 million adult Australians in 2016 will develop an estimated 7.6 million cancers during their lifetime, of which 1.8 million (24%) will be attributable to exposure to modifiable risk factors. Cancer sites with the highest number of future attributable cancers were colon and rectum (n = 717,700), lung (n = 380,400), and liver (n = 103,200). The highest number of future cancers will be attributable to exposure to tobacco smoke (n = 583,500), followed by overweight/obesity (n = 333,100) and alcohol consumption (n = 249,700). CONCLUSION: A significant proportion of future cancers will result from recent levels of exposure to modifiable risk factors. Our results provide direct, pertinent information to help determine where preventive measures could best be targeted.

Disparities in exposure to workplace hazards exist between Maori and non-Maori workers in New Zealand, with Maori workers generally incurring poorer conditions. This study aimed to determine if these ethnic disparities are similar after migration to Australia. A national cross-sectional telephone survey asked participants what tasks they undertook in their job to assess exposure to carcinogens as well as whether they experienced ethnic discrimination, bullying, job precariousness, or job strain. A total of 389 New Zealand Caucasians and 152 Maori/Pasifika workers were recruited. After adjustment, 79% of Maori/Pasifika compared with 67% of New Zealand Caucasian workers were assessed as being exposed to at least one carcinogen at work. Maori/Pasifika workers were also more likely to report ethnic discrimination and fair or poor current health than New Zealand Caucasians. Some ethnic disparities in exposure to workplace hazards in New Zealand are apparent after migration to Australia.

Asbestos exposure is associated with many adverse health conditions including malignant mesothelioma and lung cancer as well as production of autoantibodies. Autoantibodies may serve as biomarkers for asbestos exposure in patients with cancer, and autoimmune dysfunction has been linked to increased rates of various cancers. The aim of this study was to examine the hypothesis that autoantibodies are more frequent in asbestos-exposed individuals with either lung cancer or mesothelioma than those without these conditions. Asbestos-exposed individuals from Western Australia who had lung cancer (n = 24), malignant mesothelioma (n = 24), or no malignancy (n = 51) were tested for antinuclear autoantibodies (ANA) using indirect immunofluorescence and specific extractable nuclear autoantibodies (ENA) employing a multiplexed addressable laser bead immunoassay. Contrary to the hypothesis, data demonstrated that individuals without malignancy were more likely to be positive for ANA compared to those with cancer. However, autoantibodies to histone and Ro-60 were found to be associated with lung cancer. These results support a possible predictive value for specific autoantibodies in the early detection of lung cancer and/or in our understanding of the role of autoimmune processes in cancer. However, further studies are needed to identify specific target antigens for the antibodies.

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.
RESUMO
BACKGROUND: Healthcare workers are occupationally exposed to various hazardous chemicals and agents that can potentially result in long-term adverse health effects. These exposures have not been comprehensively examined at a population level. The aim of this study was to examine occupational exposures to a wide range of asthmagens, carcinogens, and ototoxic agents among healthcare workers in Australia. METHODS: Data were collected as part of the Australian Work Exposures Studies, which were computer-assisted telephone surveys conducted in 2011, 2014, and 2016 to assess the prevalence of occupational exposures to carcinogens, asthmagens, and ototoxic agents, respectively, among Australian workers. Using data on healthcare workers, the prevalence of exposures to these agents was calculated and associations of demographic variables and occupation groups with exposure status were examined. RESULTS: The prevalence of exposure to at least one asthmagen, carcinogen, and ototoxic agent was 92.3%, 50.7%, and 44.6%, respectively. The most common exposures were to (a) cleaning and sterilizing agents in the asthmagen group; (b) shift work in the carcinogen group; and (c) toluene and p-xylene among ototoxic agents. Exposure varied by occupation, with exposure to carcinogens and ototoxic agents highest among personal carers and exposure to carcinogens most likely among nursing professionals and health and welfare support workers. CONCLUSION: The results demonstrate that a substantial proportion of Australian healthcare workers are occupationally exposed to asthmagens, carcinogens, and ototoxic agents. These exposures are more common among certain occupational groups. The information provided by this study will be useful in prioritizing and implementing control strategies.

OBJECTIVES: Various lifestyle and occupational factors have been associated with an increased risk of breast cancer, but there is limited research investigating the relationship between these factors and participation in breast cancer screening. This study explores the associations between lifestyle and occupational factors and participation in breast mammography screening among women living in Western Australia. METHODS: This study involved 1705 women aged 40 and older who participated as controls in the Breast Cancer Environment and Employment Study conducted in Western Australia. Self-reported questionnaire data were collected on participation in mammography screening, demographic factors, and lifestyle and occupational variables (smoking, physical activity, alcohol consumption, body mass index, use of contraceptive pill and hormone replacement therapy, breastfeeding, occupation, and participation in shift work). Multivariate modified Poisson regression was used to identify variables associated with ever participation in breast mammography screening. RESULTS: Just over 88% of women reported having ever had a mammogram. Likelihood of having ever had a mammogram was higher among women who had ever used hormone replacement therapy (adjusted prevalence ratio (aPR) = 1.05, 95% CI 1.02-1.07). Women who worked in clerical occupations (aPR = 1.06, 95% CI 1.01-1.11) or home duties (aPR = 1.05, 95% CI 1.00-1.11) were also more likely to report having ever had a mammogram compared with those in professional or technical occupations. CONCLUSIONS: Participation in mammography screening was found to differ by lifestyle and occupational factors. These results have important implications for public health strategies on improving screening participation.

This study explores the associations between lifestyle and occupational factors and participation in colorectal cancer (CRC) screening among men and women aged 50 and over and living in Australia. We used weighted data from the Australian National Health Survey 2014-15 to produce population estimates. Lifestyle variables investigated were smoking, physical activity, alcohol consumption, fruit and vegetable consumption, and body mass index, while the occupational variables were labour force status, occupation, and participation in shift work. Using weighted data, 1,990,287 men (55%) and 1,898,232 women (49%) reported ever-screening for CRC. Female current smokers were less likely to report ever-screening for CRC (adjusted RRâ¯=â¯0.78, 95% CI 0.64-0.96), as were men who were less physically active (aRRâ¯=â¯0.87, 95% CI 0.78-0.97), reported no alcohol consumption (aRRâ¯=â¯0.73, 95% CI 0.59-0.91), and reported eating more vegetables (aRRâ¯=â¯0.84, 95% CI 0.72-0.99). When lifestyle behaviours were combined into a healthy lifestyle index score, a significant trend was observed for both men and women, whereby those who reported engaging in more healthy behaviours were more likely to have ever-screened for CRC (pâ¯=â¯.027 men; pâ¯<â¯.001 women). No associations were observed between CRC screening and occupational variables. This is the first comprehensive assessment of the lifestyle and occupational factors associated with participation in CRC screening among men and women in Australia. Participation in CRC screening was greater among those engaging in more healthy behaviours, suggesting that an individual's pattern of lifestyle behaviours may be important in determining screening participation. These results have important implications for public health strategies on improving CRC screening participation.

Migrant workers may be more likely to be exposed to workplace psychosocial stressors (WPS) which have an affect on physical and mental health. Given the relative lack of research on this topic, the study objectives were to estimate and compare the prevalence of WPS in migrant and Australian workers and investigate associated mental health problems. Three cross-sectional surveys, two with migrant workers and one with Australian workers, were pooled to provide estimates of prevalence. Regressions were conducted to investigate associations between workers and WPS. All WPS, except unfair pay, were associated with higher probability of mental health problems. The association between WPS and mental health did differ between some migrant groups. Compared with Australian-born workers, all other migrant groups tended to have a lower risk of mental health outcomes. Interactions between WPS and migrants showed variable levels in the risk of having a mental health problem, some attenuated and some increased. The study showed that country of birth does play a part in how treatment in the workplace is perceived and responded to. Any interventions to improve workplace conditions for migrant workers need to be aware of the different experiences related to migrant ethnicity.

BACKGROUND: There is limited information on whether the prevalence of exposure to workplace carcinogens varies among shift workers and non-shift workers. METHODS: This analysis used data from the Australian Work Exposures Study-Cancer, a telephone survey which examined exposure to carcinogens in the workplace. Workers were classified as shift workers if they indicated that their usual roster ever included work between the hours of midnight and 5 am. Modified Poisson regression was used to estimate the adjusted prevalence ratios (aPRs) and 95% confidence internals (CIs). RESULTS: Among the 5425 workers, 6.88% reported being exposed to shift work. Overall, shift workers were more likely to be exposed to any carcinogen (aPR = 1.16; 95% 1.06-1.26) and to specific carcinogens such as asbestos (aPR = 1.93; 95% 1.33-2.83) than non-shift workers. CONCLUSIONS: Our study shows that there are differences in exposure to carcinogenic agents among shift and non-shift workers, and so there is a need for prevention programs in order to reduce these discrepancies.

Exposure to diesel engine exhaust (DEE) contributes appreciably to the burden of occupational cancer. This study aims to estimate the potential impact of a range of interventions on the future burden of cancer from occupational exposure to DEE in Australia. The future excess fraction method, a novel method based on the lifetime risk approach, was used to model changes in the future burden of cancer among the Australian working age population exposed to DEE at work in 2012 under various intervention strategies. The interventions modeled were based on the widely accepted hierarchy of control model. At baseline, 600 (0.4%) future bladder and 4,450 (0.6%) future lung cancer cases over the lifetime of the cohort were estimated to be attributable to occupational exposure to DEE in those exposed in 2012. Up to 2,000 of these cases were estimated to be avoidable through the use of various interventions. Exhaust hoses (engineering controls) were estimated to be particularly effective. This study provides an indication of which intervention strategies may be most useful in reducing the future burden of cancer associated with occupational DEE exposure. These results show the potential effect of changing current exposure, rather than focusing on past exposures, and thus provide relevant information for policy planning.

BACKGROUND: Limited information is available on exposure to high molecular weight (HMW) asthmagens derived from plants and on the main occupations and tasks that result in such exposure among workers. METHODS: Data were collected as part of the Australian Work Exposures Study-Asthma. We estimated adjusted prevalence ratios (aPR) using modified Poisson regression models to determine which factors were associated with exposure. RESULTS: A 12.8% of 4878 workers were exposed to HMW asthmagens derived from plants. The highest prevalence of exposure was found among farmers/animal workers, education workers, and food processing workers. The main circumstances of exposure were through handling flour, freesias, or through raising livestock. Exposure was more common among female workers (aPR = 1.26, 1.10-1.43) than males, while it was lower among workers born overseas (aPR = 0.70, 0.57-0.86) than those born in Australia. CONCLUSION: Prevention of exposure to HMW asthmagens derived from plants requires a broad strategy targeting different tasks and occupations.

OBJECTIVE: To explore work-related psychosocial stressors among people of Chinese, Vietnamese and Arabic-speaking backgrounds currently working in Australia. METHODS: In 2015, a telephone survey of 585 Vietnamese, Chinese and Arabic-speaking workers asked about workplace bullying, ethnic discrimination, job complexity, degree of control, security and fairness of payment along with demographic and employment information. Estimates of job-related psychosocial stressors were derived and regression analyses used to identify significant associations. RESULTS: At least one workplace stressor was reported by 83% of the workers in the study. Education was significantly associated with experiencing any psychosocial stressor and also with the total number of stressors. Workers aged 45 years and older were more likely to be bullied or experience racial discrimination compared with younger workers of any ethnicity. There was a greater likelihood of reporting low control over a job when the interview was conducted in a language other than English and the workers were either Chinese or Arabic. Workers on a fixed-term contract, independent of ethnicity were more likely to report a job with low security. Overall psychosocial job quality decreased with education and was associated with occupation type which interacted with ethnicity and gender. CONCLUSIONS: The results suggest that job-related psychosocial stressors are widespread but not uniform across ethnic groups. Further research into what drives differences in work experience for migrant groups would provide information to guide both employers and migrants in ways to reduce workplace psychosocial stressors.

INTRODUCTION: Farmers experience a range of carcinogenic exposures, including some pesticides, fuels, engine exhausts, metals, some organic solvents, silica, wood dusts and solar radiation. However many studies investigating the risk of cancer in farmers focus on pesticide exposure alone. The aim of this study was to determine which carcinogens Australian farmers are exposed to, the prevalence and circumstances of those exposures, and the use of protective equipment. METHODS: The study used data from the Australian Work Exposures Study (AWES) a cross-sectional study conducted in 2012 that investigated the prevalence of carcinogen exposure among Australian workers. This was supplemented with data from AWES-Western Australia (WA), conducted in 2013, which followed the same methodology but in Western Australian workers only. A total of 5498 Australian workers were interviewed about the tasks they carry out in their workplace. The 166 participants who worked in farming (126 men and 40 women, with an age range of 18-65 years) are the focus of this article. RESULTS: On average, farmers had been exposed to five different carcinogens. Highest numbers of exposures occurred among men and those working on mixed crop and livestock farms. Solar radiation, diesel engine exhaust and certain solvents were the most prevalent exposures, each with over 85% of farmers exposed. The main tasks leading to exposure were working outdoors, using and repairing farming equipment and burning waste. Sun protection and closed cabs on machinery were the most frequently used forms of protection. CONCLUSIONS: Farmers are a high risk group in relation to carcinogen exposure. The variation in tasks that they undertake results in exposure to a wide variety of different carcinogens that require similarly varied control measures.

Introduction: About half of all workers in high-income countries work in small companies. However, regulatory bodies and researchers predominantly work with large companies because they are more convenient to study and easier to reach. We aimed to estimate the prevalence of exposure to asthmagens and the use of respiratory protective equipment (RPE) by company size. Methods: This analysis used data from the Australian Work Exposures Study-Asthma, a telephone survey which investigated exposure to 27 asthmagen groups. Results: Among 4844 respondents, 18.8, 19.9, 31.9, and 29.4% of workers reported working in micro (<5 employees), small (5-19 employees), medium (20-200 employees), and large (>200 employees) companies, respectively. Compared to workers in large companies, workers in micro, small, or medium companies had higher prevalence of exposure to most asthmagens and lesser use of RPE. Conclusion: Our results suggest that policy actions and regulatory measures should target micro/small companies in order to have the greatest effect.
