- Particulate air pollution increases risk of cancer and cardiopulmonary disease, partly through oxidative stress. Traffic-related noise increases risk of cardiovascular disease and may cause oxidative stress. In this controlled random sequence study, 18 healthy subjects were exposed for 3h to diesel exhaust (DE) at 276μg/m(3) from a passenger car or filtered air, with co-exposure to traffic noise at 48 or 75dB(A). Gene expression markers of inflammation, (interleukin-8 and tumor necrosis factor), oxidative stress (heme oxygenase (decycling-1)) and DNA repair (8-oxoguanine DNA glycosylase (OGG1)) were unaltered in peripheral blood mononuclear cells (PBMCs). No significant differences in DNA damage levels, measured by the comet assay, were observed after DE exposure, whereas exposure to high noise levels was associated with significantly increased levels of hOGG1-sensitive sites in PBMCs. Urinary levels of 8-oxo-7,8-dihydro-2'-deoxyguanosine were unaltered. In auxiliary ex vivo experiments whole blood was incubated with particles from the exposure chamber for 3h without effects on DNA damage in PBMCs or intracellular reactive oxygen species production and expression of CD11b and CD62L adhesion molecules in leukocyte subtypes.

- This study evaluates respiratory symptoms, lung function, and exposure to airborne particles among waste-picking children. We enrolled 103 waste-picking children at a dump in Managua, Nicaragua and 103 children who do not pick waste. Exposure to airborne particles was assessed by area sampling. Health data were obtained from a questionnaire, clinical examination, and spirometry. Exposure effects were evaluated with multivariate regression analysis. Exposure to particles exceeded national and international standards. Wheezing among children was related to exposure status, with waste-picking children who are both "never highly exposed" and "ever highly exposed" having greater prevalence of wheezing compared to the children who do not pick waste. FEV1 among "ever highly exposed" waste-picking children with wheeze was 13% lower than non-waste-picking children with wheeze. Exposure to small particles was unacceptably high and associated with wheeze and decreased lung function.

- Occupational balance promotes health, knowledge about occupational balance among older workers is important. This qualitative study aimed to describe occupational balance among older workers in Sweden. Six focus groups and two individual interviews were conducted with 26 workers, aged 65 years and older. The findings showed that drawing on abilities and resources, a harmonious mix of occupations, as well as congruence with values and personal meaning contributed to the participants’ occupational balance. From a work perspective, organizational factors such as support from managers and having the freedom to influence work tasks, as well as work time, also contributed to occupational balance. The participants changed their occupational pattern to achieve a more harmonious mix of occupations. This change was based on values and experience derived through the meaning of occupations, and on abilities and resources. Enabling older people to achieve occupational balance and promoting health may contribute to possibilities for an extended working life and active ageing.

- Background: Reforms are changing pension systems in many European countries, in order to both restrict early retirement and force people to extend their working life. From occupational therapy and occupational science perspectives, studies focusing on aspects of working life that motivate the older worker is urgent. Aim: The aim was to describe incentives behind an extended working life among people over age 65. Method: Focus group methodology was used, with participants ages 66–71, from varying work fields: construction and technical companies and the municipal elderly care sector. Findings: Work was considered important and valuable to the degree of how challenging work was, the possibilities for inclusion in a team of colleagues and the chances for better personal finances. Amongst all, the participants expressed a feeling of a strengthened identity by being challenged and having the opportunity to manage working tasks. Conclusion: The finding showed the actual reasons behind an extended working life among older workers. However, a risk of rising social inequity may appear with increased working life if older people are forced to extend their working life due to a difficult financial situation as a pensioner. A variety of retirement options and initiatives in order to support older workers are justified.

- Social participation is important for health, and it is well known that high strain jobs impact negatively on mental and physical health. However, knowledge about the impact of psychosocial working conditions on social participation from a long-term perspective is lacking. The purpose of this study was to investigate the associations between different job types and social participation from a long-term perspective. A comprehensive public health questionnaire “The Scania Public Health Survey”, was used, and psychosocial working conditions were measured with a Swedish translation of the Job Content Questionnaire. Based on data from 1098 working respondents aged 55 at baseline and a 10-year follow-up when the respondents were not working, the analyses revealed that social participation varied by job type. Jobs with high decision latitude, as in active and relaxed jobs, seem to predict high social participation, even after cessation of employment. Besides that, the result suggests that high social participation during working life is a predictor of high social participation from a long-term perspective which promotes healthy aging. Incentives for working longer are strongly related to good working conditions. A supportive work environment with possibilities for employees to participate in decision making, i.e., high control, is vital for a sustainable working life. This may contribute to an extended working life and may also support social participation prior to retirement as well as after retirement and thus to healthy aging.

- The aim of this case study was to explore the abilities and limitations of trade unions in their response to undeclared work, which has received scant attention in research on working conditions and industrial relations. The authors use power resource theory to examine the outcome of a Swedish government initiative aimed to boost the ability of the social partners to tackle undeclared work. The findings confirm previous literature suggesting cross-sectoral differences in the extent and nature of undeclared work and an association between low levels of power resources and high risk of undeclared work. The authors recommend that future initiatives take account of cross-sectoral differences in the nature and extent of undeclared work and available power resources. Future research should consider how different actors can contribute to the ability of the social partners in different sectors to engage in the battle against undeclared work.

Ingår i: International Journal of Gerontology & Geriatric Research. - 2688-8548. ; 1:1
-
Tidskriftsartikel (refereegranskat)abstract
- Raising older workers’ participation level is a key objective in many countries. It is important therefore, to deepen the knowledge regarding older workers’ work situations.The objective of the present study was to describe how managers perceived older workers, and an extended working life, in Sweden.Seven focus groups, with a total of 26 managers, were conducted; with participants coming from municipal care, or from private companies. Data was analyzed using content analysis.Five categories emerged in the analysis: Work capacity, Education, Technical devices and ergonomics, Organizational and technological changes, and Sustainable and extended working life.Managers’ attitudes range from positive to negative, confirming previous research, and strengthening the evidence. However, managers in the present study emphasized differences between blue and white collar workers’ ability to extend working life. Furthermore, these managers thought that there were greater differences between different individuals than between different age groups.

- OBJECTIVE--The aim was to investigate associations between exposure to mineral fibres and dust, and cancer in subsites within the large bowel. DESIGN--Pooled retrospective cohort studies. SUBJECTS AND SETTINGS--Blue collar workers, employed for at least one year in different trades; asbestos cement or cement workers (n = 2507), other industrial workers (n = 3965), and fishermen (n = 8092). MAIN OUTCOME MEASURES--Standardised incidence ratios (SIRs, national reference rates) were calculated for cause specific cancer morbidity between 1958 and 1989. The observation period began 15 years after first employment. RESULTS--The asbestos cement and cement workers had a slightly increased risk of colorectal cancer (SIR 1.5; 95% confidence interval (95% CI) 1.1-2.0). This was due to an increase only in the right part of the colon (SIR 2.5; 95% CI 1.6-3.8). The ratio of right (7th revision of the International Classification of Diseases ICD-7) 1530-1531)/left (ICD-7 1532-1533) colon cancer among the asbestos cement and cement workers of 4.8 differed significantly from the ratio both among the other blue collar workers (0.4) and among the fishermen (1.5). As the sensitivity and accuracy was insufficient, mortality data did not show the excess of cancers in the right part of the colon. CONCLUSIONS--An increased incidence of cancer in the right part of the colon was evident in the asbestos cement and cement workers. The distribution of cancers within the colon was noticeably different from that in other blue collar workers, indicating that our findings cannot be explained by socioeconomic confounding factors. A detailed and appropriate disease classification, based on incidence data, is necessary in order not to obscure or underestimate effects of exposure in epidemiological studies on colorectal cancer.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE--To investigate whether a lack of glutathione-S-transferase mu (GSTM1) activity was related to an increased risk for adverse outcome after asbestos exposure. METHODS--A study was made of 78 male former asbestos cement workers, with retrospective cohort data on exposure, radiographical findings, and lung function. Venous blood samples were obtained for the analysis of GSTM1 polymorphism by the polymerase chain reaction technique. Chest x ray films were classified according to the International Labour Organisation (ILO) 1980 classification. Vital capacity (VC) and forced expiratory volume during 1 s (FEV1) were determined. Individual estimates of asbestos exposure were calculated, and expressed as duration of exposure, average exposure intensity, and cumulative dose. Data on smoking were obtained from interviews. RESULTS--The lung function in the study group was reduced, compared with reference equations. 23% of the workers had small opacities > or = 1/0, 29% circumscribed pleural thickenings, 14% diffuse thickenings, and 12% obliterated costophrenic angles. 54% of the workers were GSTM1 deficient. They were comparable with the other workers in age, follow up time (median 30 years), and duration of exposure (median 18 years), but had a slightly higher cumulated dose (median 18 v 10 fibre-years) than the others. Neither in radiographical changes nor lung function variables were there any differences between the different GSTM1 groups. The findings were similar when smoking habits and estimated asbestos exposure were taken into account. CONCLUSIONS--We could not show that lack of GSTM1 activity was related to an increased risk for radiographical or lung function changes in a group of asbestos cement workers, followed up for a long period after the end of exposure.
