Background: Although job-related diseases result in more deaths per year than job-related injuries, most research concerning ethnic minority workers has concerned accidents and injuries rather than disease-causing exposures such as carcinogens. Methods: We conducted a telephone-based cross-sectional survey to estimate the prevalence of occupational exposure to carcinogens among a sample of ethnic minority workers in Australia, and compared their exposure prevalence to that of a sample of the general Australian-born working population ('Australian workers'). Results: One-third of the ethnic minority workers were exposed to at least one carcinogen at work. The likelihood of exposure to carcinogens was not significantly different from that of Australian workers, although the likelihood of exposure to individual carcinogens varied by ethnicity. Conclusion: Knowing the prevalence of exposure to carcinogens in the workplace in different ethnic groups will allow better targeted and informed occupational health and safety measures to be implemented where necessary.

INTRODUCTION: The aims of this study were to produce a population-based estimate of the prevalence of work-related exposure to lead and its compounds, to identify the main circumstances of exposures, and to collect information on the use of workplace control measures designed to decrease those exposures. METHODS: Data came from the Australian Workplace Exposures Study, a nationwide telephone survey which investigated the current prevalence and circumstances of work-related exposure to 38 known or suspected carcinogens, including lead, among Australian workers aged 18-65 years. Using the web-based tool, OccIDEAS, semi-quantitative information was collected about exposures in the current job held by the respondent. Questions were addressed primarily at tasks undertaken rather than about self-reported exposures. RESULTS: A total of 307 (6.1%) of the 4993 included respondents were identified as probably being exposed to lead in the course of their work. Of these, almost all (96%) were male; about half worked in trades and technician-related occupations, and about half worked in the construction industry. The main tasks associated with probable exposures were, in decreasing order: soldering; sanding and burning off paint while painting old houses, ships, or bridges; plumbing work; cleaning up or sifting through the remains of a fire; radiator-repair work; machining metals or alloys containing lead; mining; welding leaded steel; and working at or using indoor firing ranges. Where information on control measures was available, inconsistent use was reported. Applied to the Australian working population, approximately 6.3% [95% confidence interval (CI) = 5.6-7.0] of all workers (i.e. 631000, 95% CI 566000-704000 workers) were estimated to have probable occupational exposure to lead. CONCLUSIONS: Lead remains an important exposure in many different occupational circumstances in Australia and probably other developed countries. This information can be used to support decisions

INTRODUCTION: The aims of this study were to produce a population-based estimate of the prevalence of work-related exposure to polycyclic aromatic hydrocarbons (PAHs), to identify the main circumstances of exposure and to describe the use of workplace control measures designed to decrease those exposures. METHODS: The analysis used data from the Australian Workplace Exposures Study, a nationwide telephone survey which investigated the current prevalence and exposure circumstances of work-related exposure to 38 known or suspected carcinogens, including PAHs, among Australian workers aged 18-65 years. Using the web-based tool OccIDEAS, semi-quantitative information was collected about exposures in the current job held by the respondent. Questions were addressed primarily at tasks undertaken rather than about self-reported exposures. RESULTS: Of the 4,993 included respondents, 297 (5.9%) were identified as probably being exposed to PAHs in their current job [extrapolated to 6.7% of the Australian working population-677 000 (95% confidence interval 605 000-757 000) workers]. Most (81%) were male; about one-third were farmers and about one-quarter worked in technical and trades occupations. In the agriculture industry about half the workers were probably exposed to PAHs. The main exposure circumstances were exposure to smoke through burning, fighting fires or through maintaining mowers or other equipment; cleaning up ash after a fire; health workers exposed to diathermy smoke; cooking; and welding surfaces with a coating. Where information on control measures was available, their use was inconsistent. CONCLUSION: Workers are exposed to PAHs in many different occupational circumstances. Information on the exposure circumstances can be used to support decisions on appropriate priorities for intervention and control of occupational exposure to PAHs, and estimates of burden of cancer arising from occupational exposure to PAHs.

Objective: To estimate the numbers and proportions of cancers occurring in Australia in 2010 attributable to modifiable causal factors. Methods: We estimated the population attributable fraction (PAF) of cancers associated with exposure to 13 causal factors using standard formulae incorporating exposure prevalence and relative risk data. We also calculated the potential impact of changing exposure to some factors. Results: A total of 32% of all cancers diagnosed in Australia in 2010 (excluding keratinocyte cancers) were attributable to the 13 factors assessed (men 33%; women 31%). Leading factors were tobacco smoke (PAF all cancers: 13.4%), solar radiation (6.2%), inadequate diet (6.1%) and overweight/obesity (3.4%). Factors conferring highest PAFs differed by sex: highest PAFs for men were tobacco smoke (15.8%), solar radiation (7.1%) and alcohol (3.0%); while highest PAFs for women were tobacco smoke (10.1%), solar radiation (5.0%) and overweight/obesity (4.5%). Sites with the highest counts of potentially preventable cancers were lung (8,569), colorectal (7,404), melanoma of the skin (7,220) and breast (3,233). Conclusions: At least one in three cancers in Australia is attributable to exposure to known modifiable factors. Implications: Up to 37,000 cancers could be prevented in Australia each year if the population avoided exposure to 13 common factors known or strongly suspected to cause cancer.

Objective: To develop a comprehensive list of asthmagens which may occur in occupational settings in Australia. Methods: Potential asthmagens considered for this list were identified through work health and safety classification databases in Australia and through lists developed by professional associations in other countries. Inclusion criteria were: there is evidence that the agent is asthmagenic; it is used in occupational settings; and it is available in Australia. Results: The final list contained 277 asthmagens in 27 groups that may be found in occupational circumstances in Australia. Three other agents that have been documented as asthmagens in Australia were included: almond dust, fluoride (in aluminium pot room fumes); and sawdust from the Australian Blackwood. Conclusions: This is the first comprehensive and inclusive list of Australian occupationally relevant asthmagens to have been compiled. Implications: This list is specific for Australian workplace exposure to asthmagens. It will help focus policy and preventative practices and reduce the burden of occupational asthma. It will also be useful in future studies to identify those who are exposed to the asthmagens and provide information to assist regulators to identify industries, occupations, specific activities and existing exposure standards that can be targeted to improve worker health and welfare.

Background/Objectives: Limited research indicates that using English language only surveys in prevalence studies conducted in the general population or in specific ethnic populations may result in unrepresentative samples and biased results. In this study, we investigated whether participants from ethnic minorities who chose to answer a study interview in a language other than English (LOTE) differed from those who completed the interview in English. Methods: This study was conducted within an Australian population-based telephone survey that assessed the prevalence of occupational exposure to carcinogens among 749 ethnic minority workers. We used modified Poisson regression to determine the factors associated with completing the interview in a LOTE. Results: Participants who elected to complete the interview in a LOTE differed from those who completed it in English on several factors, including sex, country of birth, education, occupation, and occupational exposure to carcinogens (40% compared with 29%, P < 0.01). Conclusions: The participants who chose to complete the study interview in their native language had several demographic differences from those participants who completed it in English, and were more likely to be exposed to carcinogens at work. Prevalence studies that offer only English language study instruments are unlikely to produce representative samples of minority groups, and may therefore produce biased results.

This study investigated the potential mediating roles of body comparisons with peers and models in the relationship between the internalization of thinness norms and body image concern. A total of 224 Western Australian girls aged 14-15 completed questionnaires assessing their endorsement of thinness norms, body image concerns, and frequency of body comparisons with peers and with models. Both targets of body comparisons were found to significantly mediate the relationship between the endorsement of thinness norms and body image concern, with body comparison with peers a stronger mediator than comparison with models. These findings show that body comparison with peers, in particular, plays a significant role in the experience of body image concerns among adolescent girls, and should be given a higher profile in programs designed to prevent or reduce body image concern. © 2013 Elsevier Ltd.

Objective. To develop a job-exposure matrix (JEM) that estimates exposure to eight variables representing different aspects of shiftwork among female workers. Methods. Occupational history and shiftwork exposure data were obtained from a population-based breast cancer case–control study. Exposure to light at night, phase shift, sleep disturbances, poor diet, lack of physical activity, lack of vitamin D, and graveyard and early morning shifts, was calculated by occupational code. Three threshold values based on the frequency of exposure were considered (10%, 30% and 50%) for use as cut-offs in determining exposure for each occupational code. JEM-based exposure classification was compared with that from the OccIDEAS application (job-specific questionnaires and assessment by rules) by assessing the effect on the OR for phase shift and breast cancer. Using data from the Australian Workplace Exposure Study, the specificity and sensitivity of the threshold values were calculated for each exposure variable. Results. 127 of 413 occupational codes involved exposure to one or more shiftwork variables. Occupations with the highest probability of exposure shiftwork included nurses and midwives. Using the 30% threshold, the OR for the association between phase shift exposure and breast cancer was decreased and no longer statistically significant (OR=1.14, 95% CI 0.92 to 1.42). The 30% cut-off point demonstrated best specificity and sensitivity, although results varied between exposure variables. Conclusions This JEM provides a set of indicators reflecting biologically plausible mechanisms for the potential impact of shiftwork on health and may provide an alternative method of exposure assessment in the absence of detailed job history and exposure data.

Peers may influence the body image concerns and disordered eating behaviours of adolescent girls through the creation of appearance cultures within friendship cliques. The present study investigates the role of friendship cliques and school gender composition in impacting upon adolescent girls' body image concern and disordered eating behaviours, using hierarchical linear modelling (HLM), a statistical procedure employed in the analysis of nested data. A sample of 156 girls was drawn from four private schools located in the capital city of Western Australia (one single-sex school and three mixed-sex schools). Eighty students from the single-sex school and 76 female students from the mixed-sex schools, comprising 35 friendship cliques, completed questionnaires assessing body image, disordered eating, and a range of variables that have previously been associated with body image concern and disordered eating, including appearance-based social comparison, frequency of appearance-based conversation, appearance-based criticism, friends' concern with thinness, media influence and media pressure. Hierarchical linear modelling analyses found that friendship cliques in all-girls schools exhibited similar levels of body image concern and dieting behaviours, with various peer and other media influence variables accounting for these similarities. Friendship cliques in mixed-sex schools were not found to be similar with regard to body image concern or disordered eating. These findings support the notion that friendship groups can be an important source of influence on the body image concerns of adolescent girls in single-sex schools, and show that both individual and friendship clique level measures of attitudes and behaviours make independent contributions to the prediction of these body image concerns. © 2013 Springer Science+Business Media New York.

High school is a key venue for the development and expression of body image concerns in adolescent girls. Researchers have begun to investigate the role of school-based 'appearance cultures' in magnifying the body image concerns of students. To date, however, no research has examined girls' experience as participants within these cultures, and thus the opportunity to learn how girls account for the development and maintenance of these cultures has been missed. In interviews with nine girls attending an all-girls' school, the existence of a strong 'appearance culture' in the school was identified as a major influence on the body image concerns of students. Girls talked about the ways in which appearance-focused conversations, dieting, and weight monitoring occurred as part of the everyday interaction with friends and peers at school. They also identified many ways in which their school attempted to address body image concerns, although these attempts were often portrayed as ineffective, if not counter-productive. These findings suggest that attempts to address the body image concerns of students will need to be sensitive to the lived reality of appearance cultures within schools. © The Author(s) 2010.

Body image is a particularly troubling issue during adolescence, with many reporting significant weight and shape concerns during this time. The surrounding sociocultural environment can be seen to be integral to the experience of these concerns, and to shape the form they subsequently take. A major context in which this culture may manifest and be reproduced is the school environment, with the high school being seen as a key venue for the development and expression of body image concerns in adolescent girls. More specifically, the school environment may contribute through body perfection codes and dominant discourses embedded in the curricular structure and general school ethos, or in a more informal way through the formation of peer appearance cultures, which have been found to contribute to eating disorders and related issues in adolescent girls. This thesis aimed to further examine the role of the school environment in contributing to body image concerns and disordered eating in adolescent girls, using a mixed-methods design. The first stage of this project, an ethnographic analysis, focused on the transmission of, and value placed upon, body image and weight concerns in a particular all-girls‟ school. Interviews (both group and individual) and open-ended surveys, as well as observations and textual analysis, were employed in this phase of the project, with data collected from teachers, parents, and students. Results indicated that an appearance-based culture was evident in this school environment, with students, parents and staff members all noting the importance of the school, and peers in particular, in fostering weight consciousness and influencing eating habits. Following this, the contribution of the school and friendship groups to body image and weight concerns was quantitatively examined. Questionnaires were administered to 314 students (224 females and 90 males) from 2 coeducational schools and an all-girls‟ school, in a replication and extension of a p
