Background. Because driving takes place outside of company premises, access for professional drivers to workplace health promotion (WHP) is hindered. In the following cross-sectional study, we surveyed WHP experiences and needs from the viewpoint of entrepreneurs in order to gain insight into necessary preventative measures. Material and methods. Managers of transport companies were asked for their opinion, knowledge, experiences and plans regarding WHP. Additionally, we obtained information about their willingness to participate in a pilot project. The 10% random sample was taken from the list of a statutory accident insurance association. The results were correlated with the likely predictor variables company size, engagement in long- or short-distance traffic and WHP experience. Results. Of the responding entrepreneurs (n=598, =11% response rate), 22% had prior experience with preventative health measures for their workers; the rate depends on the company size. One third of the respondents signalled a general willingness to participate in a prevention project and detailed their preferences. Conclusions. The current practice of WHP in transport companies is deficient. However, at least a small percentage of transport entrepreneurs are receptive to information campaigns and need-based WHP offers. © Springer-Verlag 2011.

Objective: The aim of this study is to investigate the association between five-year changes in occupational sitting and body mass index (BMI) in working adults. Methods: We analyzed data from The Danish Work Environment Cohort Study (2005 and 2010, n= 3.482). Data on occupational sitting, weight, height and several potential confounders were self-reported. The association between change in occupational sitting (hours) (categorized as large decrease <. - 7.5, moderate decrease - 7.5 to <. - 2.5, no change - 2.5 to 2.5, moderate increase >. 2.5 to 7.5 and large increase >. 7.5) and change in BMI was explored by multiple linear regression analyses. Results: 43.0% men and 36.1% women had high occupational sitting time (≥ 25. h per week) at baseline. 31.8% men and 27.2% women decreased while 30.0% men and 33.0% women increased occupational sitting. The proportion of obese (BMI. ≥ 30) increased almost 3% for both genders. BMI changed 0.13 (CI: 0.06; 0.20, p= 0.0003), per category of change in occupational sitting in women, but no association was found in men. Conclusion: In women, there is a positive association between five-year changes in occupational sitting and BMI. © 2015 Elsevier Inc.

Recycling and waste management is performed in about 5,300 enterprises by about 150,000 employees in Germany. The Federal Institute for Occupational Safety and Health (BAuA) has performed a comprehensive investigation program in different recycling enterprises during the last decade. In detail, workers' exposures have been measured when recycling electronic waste, end-of life vehicles, plastics waste, textile, and paper and paperboard. During all these processes workers are exposed to airborne particles. Additionally, when recycling electronic waste and end-of life vehicles a significant exposure to heavy metals and organic solvents was found, respectively. Furthermore, for plastics, textiles, and paper and paperboard recycling exposure to biological agents may reach considerable concentrations. The results of the workplace measurements were used to establish recommendations for good practice to protect workers in recycling enterprises.

Musculoskeletal disorders are the leading cause of sick leave. Because of the importance of back pain and knee osteoarthritis (ICD-10 diagnoses M54 and M17), these conditions are considered in detail. The aim of this study was to clarify whether job-specific differences in the incidence of sick leave events due to these disorders vary depending on age. The study was based on a secondary analysis of data on sick leave from almost all statutory health insurances in 2008. The database contains aggregated data on sick leave of approximately 26.2 million insured employees. The occurrence of sick leave events resulting from the M54 and M17 diagnoses was defined as the outcome variable. The assignment of employees to occupational groups (BLOSSFELD classification) was considered as the exposure variable. We calculated the morbidity ratios (SMR) of sick leave occurrence stratified by sex and age. The risk of sick leave was increased for both genders and for both diagnoses, particularly in the occupational groups of the production and service industries with low and medium skill level, even after stratification according to age. Sick leave due to these disorders is a significant issue in these occupations regardless of age, and must be considered with regard to social and preventive aspects. © Springer-Verlag Berlin Heidelberg 2013.

Cardiovascular diseases (CVD) are responsible for a major part of morbidity and mortality. Based on two selected diagnoses (ICD-10) "essential hypertension" (I10) and "acute myocardial infarction" (AMI, I21) the occupational- and age-dependent increases in sick leave are described. The secondary data analysis is based on gender-stratified, pooled data (26.2 million legally insured) on sick leave of the German social security workforce in 2008. The number of sick leave cases stratified by sex and age were calculated. Indirectly standardized morbidity ratios (SMR) for the occurrence of sick leave cases stratified by age and occupational groups (according to Blossfeld) with 99.99% confidence intervals are estimated. Age had an influence on the professional group-dependent sick leave. In the youngest age group, a similar risk existed for hypertension and AMI in all occupational groups. In the middle and older age groups, low-skilled service workers and manual occupations had increased risks for both men and women as compared to the occupational group of qualified sales and administrative occupations. Because the workforce is expected to continue to age in the future, primary and secondary prevention of CVD in all age groups is strongly recommended. © Springer-Verlag Berlin Heidelberg 2013.

Concentrations of microorganisms can be measured in different ways. One method is the fluorescence-based microscopically total cell counting after DNA-staining by DAPI. To verify adequacy of this method for microbial exposure assessment at workplaces, replicate determinations of bioaerosol samples were performed. Initially it was identified which area of a polycarbonate filter (335 mm2) has to be investigated in order to obtain representative cell counting results. Depending on average number of cells per mm2 it was found, that either 0.8 mm2 (distributed to 80 sub-sections) or 0.3 mm2 (distributed to 30 sub-sections) of a polycarbonate filter has to be analysed in cases of 100 to 200 cells mm-2 or > 200 to 20,000 cells mm-2, respectively. Subsequently, all bioaerosols were investigated by this counting convention. Depending on origin of investigated bioaerosols and the laboratory worker, the variation coefficient ranged between 4 and 13% if one sample has been analysed five times by one laboratory worker. The variation coefficient increased to 26 to 31% when one sample was analysed by different workers (n = 4). In general, the results obtained in the present study show that the total cell count approach offers adequate accuracy and reproducibility for quantitative analyses of biological agents in bioaerosol samples from workplaces.


In this study the effects of temporal variations in individual work steps for the DAPI total cell count approach were investigated. It was shown that 24-hour storage (4°C) of the original bio-aerosol samples (loaded polycarbonate filters) did not result in quantification differences. Therefore, a period of 24 hours (e.g. time of transport) before further processing in the laboratory is tolerable. The reaction time of formaldehyde for cell fixation should be at least 24 hours. Subsequent to the fixation procedure, the samples can be stored at 4°C for up to two years without any considerable changes in the detection efficiency. Staining time with DAPI should be at least 30 minutes. The DAPI-stained bioaerosol samples, however, must then be analysed microscopically within several hours because storage at room temperature, even in the dark, will lead to substantial detection losses. The results of this study provide sufficient evidence to describe a uniform standardized procedure for the quantification of a work-related microbial exposure level using the DAPI total cell count approach.

As a partner in several publicly-funded research projects, the Federal Institute for Occupational Safety and Health (BAuA) performed workplace exposure measurements during the production and handling of nano-materials. Funding was provided by the Federal Ministry of Education and Research (BMBF) and the European Union. Herein, different measuring devices for inhalation exposure were tested and measurement strategies established. In addition, the dust behaviour of fibrous nano-materials was investigated on a test stand focussing on the morphology of the resulting fibre dust. It was shown that for some materials, individual fibres can be released which meet the WHO criteria for carcinogenic fibres. This approach is based on the conclusions from the research projects and a presentation given at the Nordbadisches Forum "Gesundheit und Sicherheit bei der Arbeit" ("Health and safety at work") in Mannheim.

The second questionnaire campaign conducted by the German Federal Institute for Occupational Safety and Health (BAuA) on the handling and production of nanomaterials in Germany accommodates the increasing importance of the nanotechnology branch. The aim was to update the first questionnaire campaign on focus point in nanotechnology and to deepen several issues from that campaign in order to be able to derive a need of action when recommending possible safety measures. The survey gives an overview of the different industry branches that produce, process and release nanomaterials. Statements are given on the amount and kind of produced and processed nanomaterials in Germany and to the safety measures applied while handling these substances Industry mainly produces and uses the traditional materials listed on the OECD list of manufactured nanomaterials. Multi walled carbon nanotubes (MWCNT) are the most important materials for research institutions. The exposure measurements showed short-time peak concentrations in particle number concentration above the background. Future exposition measurements shall focus their causes and sources. First findings on experience and application of occupational hygiene management systems for the handling of nanomaterials in work sites were gathered and evaluated.

"Dynamic", "complexity", and "diversity" are terms that best describe the challenges in the workplace resulting from the changing nature of work. These changes should conform to the criteria of human-related work design. However, the number of pensions for reduced earning capacity and the number of unfit for work days caused by psychic disorders are rising. Affective disorders, including depression, are the largest group. Depression represents a long-term consequence of work demands. Empirical results confirm a significant relationship between depression and the objective existing as well as the subjective perceived workload conditions. Burn-out as a further long-term consequence depends inter alia on the design of the physical work demands, the environmental conditions, the psychosocial conditions, and the transparency of the decision and information processes in a company. Additionally, empirical results show that the short-term consequences of work demands, i.e., fatigue, satiation, and monotony correlate with the burn-out components of exhaustion and alienation from work. Furthermore, using restructuring as an example, it is demonstrated that the changes in work that accompany modifications in the working world also have other health-related consequences. © Springer-Verlag Berlin Heidelberg 2013.
