Impact of atopic dermatitis on occupational contact dermatitis among young people: A retrospective cohort study.

BACKGROUND: Occupational contact dermatitis (OCD) is a common occupational disease. Atopic dermatitis (AD) is a known risk factor for OCD. OBJECTIVES: To determine the prevalence of previously diagnosed AD among young workers with recognized OCD and assess its impact on OCD prognosis. METHODS: A retrospective cohort study. A questionnaire was sent to 6251 workers with recognized OCD who were under 35 years at notification (response rate: 47%). Of the respondents, 2392 answered a question about previous doctor-diagnosed AD and were included in the study. Eczema severity, occupational consequences and quality of life were examined using statistical analyses comparing workers with and without previously diagnosed AD. RESULTS: The prevalence of previously diagnosed AD was 41.8% (95% CI: 39.8-43.8). Women had a higher AD prevalence, and workers with AD reported OCD at a younger age. Workers with AD reported more frequent and severe eczema symptoms and had a higher risk of OCD negatively affecting job and occupation choices. Health-related quality of life was more adversely affected in workers with AD. CONCLUSIONS: AD significantly impacts severity and has long-term consequences for young people with OCD. Targeted prevention strategies need to be developed.

Assessing the efficacy of a German-inspired intervention on occupational contact dermatitis in Denmark: A randomised controlled trial with 3-month follow-up.

BACKGROUND: Occupational contact dermatitis (OCD) is a prevalent, often chronic disease that poses a risk for job loss and decreased quality of life. In Germany, a multi-step prevention programme emphasising early detection and highly specialised multidisciplinary treatment has been implemented with great success. OBJECTIVES: To examine the effectiveness of a Danish-adapted version of the German prevention effort on OCD severity, quality of life and occupational consequences at 3-month follow-up. METHODS: Randomised, controlled trial. Participants were recruited after the first referral from General Practitioner to Dermatologist with suspected OCD. The intervention group (IG) received a Danish-adapted, multidisciplinary intervention, while the control group (CG) navigated the Danish healthcare system without interference from the study. OCD severity, occupational consequences and quality of life were assessed at 3-month follow-up using self-reported questionnaires. RESULTS: A statistically significant decrease in the severity of eczema was found at 3-month follow-up in the IG compared to the CG. The IG were statistically significantly more likely to have seen a dermatologist at 3-month follow-up. Higher treatment level in the IG was indicated by the results but was not statistically significant. No significant difference was found in quality of life or occupational consequences. CONCLUSIONS: These initial findings suggest that early and specialised treatment of OCD improves OCD prognosis.

Mental illness rates among employees with fixed-term versus permanent employment contracts: a Danish cohort study.

PURPOSE: It has been hypothesized that employment in a fixed-term instead of permanent contract position is associated with an increased risk of development of mental health problems. The present study aimed at estimating rate ratios between fixed-term and permanent employees in the Danish labor force, for use of psychotropic drugs and psychiatric hospital treatment due to mood, anxiety or stress-related disorders, respectively. METHODS: Employment data were drawn from the Danish Labor Force Survey of 2001-2013, which is a part of the European Labor Force Survey. Full-time employed survey participants without mental illness at the baseline interview (N = 106,501) were followed in national health registers for up to 5 years. Poisson regressions were used to estimate rate ratios for redeemed prescriptions of psychotropic drugs and psychiatric hospital treatments due to mood, anxiety or stress-related disease. The analyses were controlled for age, gender, industrial sector, nighttime work, level of education, calendar year, disposable family income and social transfer payments within 1 year prior to the baseline interview. RESULTS: The rate ratio for hospital diagnosed mood, anxiety or stress-related disorders among employees with fixed-term vs. permanent employment contracts was estimated at 1.39 (99.5% CI 1.04-1.86), while the corresponding rate ratio for redeemed prescriptions of psychotropic drugs was estimated at 1.12 (99.5% CI 1.01-1.24). CONCLUSION: The present study supports the hypothesis that employment in a fixed-term rather than permanent contract position is associated with an increased risk of developing mental health problems.

Do baseline industry and job group skill level predict welfare dependency at 1, 3 and 5 years after mental health related sickness absence? A Danish cohort study.

BACKGROUND: The cost of mental ill health in the EU-28 nations has been estimated at approximately 4.1% of the total gross domestic products (GDP). Improved rates of return to sustainable employment among people who are sick-listed due to mental ill health would decrease spending on welfare benefits. The present cohort study provides statistical information that may be helpful in the design and prioritizing of efforts aimed at reducing the burden of sickness absence due to mental ill health among employees in the general working population of Denmark. Our primary aim was to estimate odds of being i) deceased or recipient of health related welfare benefits and ii) recipient non-health related welfare benefits, compared to being alive and self-reliant at 1, 3 and 5 years after first visit to a jobs and benefits office due to mental health related sickness absence, as a function of industrial sector and job group skill level at baseline. A secondary aim was to analyze these odds as a function of baseline age, gender, type of mental ill health, family type and employment status. METHODS: The study population consisted of 20-54 year-old persons on long-term sickness absence due to mental health problems in 21 Danish municipalities in 2010-2012 (N = 19,660). Odds ratios were estimated by use of multinomial logistic regression. The outcomes were ascertained through national registers. RESULTS: We did not find any statistically significant association between baseline industrial sector or job group skill level and welfare dependency at follow-up. In the secondary analyses, the estimated odds of health and non-health related welfare dependencies at follow-up tended to increase with unemployment, age, being single and being on sick leave due to self-reported anxiety or depression versus stress/burnout at baseline. CONCLUSIONS: The present study does not support that industry and job group skill level predict welfare dependency after health related sickness absence, after adjustment for relevant covariates, in the general population of Denmark. It suggests, however, that the vulnerability lies in population groups characterized by unemployment, older age, being single and being on sick leave due to self-reported anxiety or depression versus stress/burnout.

Fixed-term contract positions, unemployment and mental ill health: a Danish cohort study.

BACKGROUND: Both perceived job insecurity and unemployment has been associated with an increased risk of developing mental ill health. It has, moreover, been proposed that an insecure employment may be as detrimental as unemployment itself. OBJECTIVE: To estimate incidence rate ratios (RRs) of (i) redeemed prescriptions for psychotropic drugs and (ii) psychiatric hospital treatment due to mood, anxiety, or stress-related disease, among fixed-term contract workers (as an operationalization of insecure job) vs. unemployed, in the general population of Denmark. METHODS: Data on baseline employment status were drawn from the Danish Labor Force Surveys in the years 2001-2013. Participants (10,265 fixed-term contract workers and 7926 unemployed) were followed for up to 5 years in national registers (2439 cases of psychotropic drug use, 71,516 person years; 311 cases of psychiatric hospital treatment, 86,790 person years). Adjusted RRs were obtained by Poisson regression. We aspired to minimize health selection effects by (i) exclusion of survey participants who received sickness benefits, social security cash benefits, psychiatric hospital treatment or a prescription for psychotropic drugs, within 1-year prior to baseline (n = 11,693), (ii) adjustment for age, gender, level of education, calendar year, disposable family income and maternity/paternity benefits within 1-year prior to baseline. RESULTS: The adjusted RR for fixed-term contract workers vs. unemployed was 0.98 (99.5% CI: 0.87-1.11) for psychotropic drugs and 0.93 (99.5% CI: 0.67-1.30) for psychiatric hospital treatment. CONCLUSION: The present study did not find significant differences in the risk of developing mental ill health between fixed-term contract workers and unemployed, and thus suggests that fixed-term contracts may be as detrimental as unemployment.

Occupational contact dermatitis among young people in Denmark - A survey of causes and long-term consequences.

BACKGROUND: Studies on the causes and consequences of occupational contact dermatitis (OCD) among young workers are non-existent. OBJECTIVES: Determine causes and consequences of OCD among workers younger than 35 years of age. METHODS: A questionnaire was sent to 6251 workers younger than 35 years at notification with recognized OCD (response rate 47%). RESULTS: The most prevalent occupations were health care workers, kitchen workers, nursery teachers, and hairdressers and beauticians. Seventy-six percent still had eczema, and 77% of these had eczema half to all the time over the last 3 months, with 61% evaluating their eczema as moderate to very severe. Fifty-three percent had changed their occupation since notification, and 42.5% had lost their job because of OCD. Allergic OCD increased the odds ratio (OR) for facial or foot eczema, job loss, change in work tasks, difficulties finding work, decrease in income, and sick leave. Age at notification of 25 years of age or younger increased the risk of job loss and feeling restricted in choice of job. Workers in the food industry had a higher OR for job loss, whereas hairdressers and beauticians had a higher risk of job loss and a decrease in income. CONCLUSIONS: The severe, long-term consequences of OCD notification signify the need for further preventive strategies among young workers.

Associations between physical and psychosocial work environment factors and sickness absence incidence depend on the lengths of the sickness absence episodes: a prospective study of 27 678 Danish employees.

OBJECTIVES: This study examined if the association between work environment factors and sickness absence (SA) depended on the inclusion or exclusion of short-term SA episodes. METHODS: We linked the 'Work Environment and Health in Denmark' survey with the 'Danish Register of Work Absences' (n=27 678). Using covariate adjusted Cox regression, we examined the associations between work environment factors and SA by changing the cut-off points for the length of the SA episodes, for example, episodes ≥1 day, ≥6 days and ≥21 days. We examined three physical work environment factors: 'Back bend or twisted', 'Lifting or carrying', 'Wet hands' and three psychosocial work environment factors: 'Poor influence', 'Role conflicts' and 'Bullying'. RESULTS: 'Back bend or twisted' and 'Lifting or carrying' had small significant HRs for SA episodes ≥1 day and large and highly significant HRs for SA episodes ≥6 days and ≥21 days. 'Wet hands' had small significant HRs for SA episodes ≥1 day for both sexes and large and highly significant HR for ≥6 days for women. HRs of all three psychosocial factors were highly significant for SA episodes ≥1 day and ≥6 days for both sexes, and 'Poor influence' and 'Role conflicts' were significant for SA episodes ≥21 days for women. CONCLUSIONS: The physical work factors had higher associations with SA when SA episodes of 1-5 days were excluded and focus was on SA episodes ≥6 days. The psychosocial work factors were strongly associated with SA both with and without SA episodes of 1-5 days included in the analyses.

Incidence rates of occupational contact dermatitis in Denmark between 2007 and 2018: A population-based study.

BACKGROUND: Recent population-based studies on the incidence rates (IRs) of occupational contact dermatitis (OCD) are sparse. OBJECTIVES: To determine the IRs of OCD and development thereof between 2007 and 2018 in known risk occupations. METHODS: Data on all recognized cases of OCD were used to calculate IRs as the number of recognized OCD cases per 10 000 workers per year. Asymptotic chi-square test was used to compare the IRs between 2007-2012 and 2013-2018. RESULTS: The median age at notification of OCD was below 30 years for several of the examined occupations. Hairdressers and beauticians, bakers, dentists and dental assistants, and manufacturing of windmills had the highest overall IRs of OCD. We found a statistically significant increase in the IRs of OCD for child/nursery care workers. CONCLUSIONS: The median age at notification of OCD was low for several of the occupations, signifying the need for further preventive strategies among young people. Based on the IRs of OCD, future preventive efforts should be directed at hairdressers and beauticians, bakers, dentists and dental assistants, and manufacturing of windmills. Furthermore, the statistically significant increase in IRs of OCD among child/nursery care workers highlights the need for further preventive strategies in this field.

Degree of employment, sick leave, and costs following notification of occupational contact dermatitis-A register-based study.

BACKGROUND: Occupational contact dermatitis (OCD) is the most commonly recognized occupational disease in Denmark. OBJECTIVES: To examine the impact of recognized OCD on degree of employment, sick leave, unemployment, and job change. METHODS: Data on all recognized individuals with OCD notified in Denmark between 2010 and 2015 (n = 8940) were linked to information on social transfer payments in the years before and after notification. The number of weeks on unemployment benefits or sick leave and the degree of employment during the 2 years prior to notification was compared with the 2 years following notification. RESULTS: The degree of employment decreased on average 8.9 work-hours/month, corresponding to an average annual loss of income per worker of approximately €1570. The average number of weeks that workers were receiving unemployment benefits and paid long-term sick leave rose by 2.5 and 3.4 weeks, respectively, corresponding to an average additional annual cost per worker of approximately €420 and €770, respectively. Longer case-processing time was significantly associated with lower degree of employment and higher levels of unemployment and sick leave. CONCLUSIONS: OCD has a significant negative impact on employment and economics, thus highlighting the need for a national, strategic action plan for effective prevention of OCD.

Perceived stress and sickness absence: a prospective study of 17,795 employees in Denmark.

OBJECTIVES: The aims were to examine (1) the prospective association between perceived stress and sickness absence, and if this association (2) differed by sex, and (3) was stronger when only long-term sickness absence (≥ 31 days) instead of all-length sickness absence (≥ 1 day) was included. Moreover, different cut-points for the length of the sickness absence periods were applied. METHODS: We followed respondents (10,634 women and 7161 men) from the 'Work Environment and Health in Denmark' 2014-survey for up to 18 months in the 'Register of Work Absences' from Statistics Denmark. Perceived stress was measured by a single question: "In the last 2 weeks, how often have you felt stressed?" We used Cox-regression with repeated events, adjusted for age, sector, education, and previous sickness absence. RESULTS: The hazard ratio (HR) for all-length sickness absence (≥ 1 day) for "Often/Always" stress compared to "Seldom/Never" stress was statistically significant among both men (HR = 1.25 [1.13-1.38]) and women (HR = 1.43 [1.34-1.51]). The HR was statistically significant for women (HR = 2.26 [1.89-2.70]), but not for men (HR = 1.22 [0.86-1.73]), when the analyses were restricted to long-term sickness absence (≥ 31 days). The sex-difference was statistically significant. Additional analyses with cut-points at ≥ 2, ≥ 4, ≥ 6, ≥ 8, ≥ 11, ≥ 15, ≥ 20, and ≥ 25 sickness absence days showed that among women, the HR increased gradually with increasing lengths of the sickness absence periods. CONCLUSIONS: The prospective association of perceived stress with risk of sickness absence was stronger among women than men. Among women, perceived stress was more strongly associated with long-term sickness absence than with all-length sickness absence.

Long-term sickness absence from combined factors related to physical work demands: prospective cohort study.

Background: The working environment plays an important role in public health. This study investigates the risk for long-term sickness absence (LTSA) from the combination of factors related to physical work demands. Methods: Employees (n = 22 740) of the general population (the Danish Work Environment & Health study 2012) were followed for two years in the Danish Register for Evaluation of Marginalisation. Using Cox regression analyses we determined the risk of LTSA from four factors; (i) physical work demands, (ii) physical exertion during work, (iii) fatigue after work and (iv) work-limiting pain. Results: During follow-up 10.2% experienced LTSA. Each of the four factors increased the risk of LTSA with hazard ratios (HR) ranging from 1.30 to 1.57. Scoring high on one (30.3% of the respondents), two (24.4%), three (19.9%) and all four factors (9.2%) gradually increased the risk of LTSA (HR's of 1.39 [95% CI 1.16-1.66], 1.66 [95% CI 1.39-1.99], 1.90 [95% CI 1.57-2.29] and 3.02 [95% CI 2.47-3.68], respectively). Risk estimates remained robust in stratified analyses of age, sex and socioeconomic position. Population attributable fractions were high across all subgroups; 39% (general population), 36% (younger workers), 45% (older workers), 36% (men), 41% (women), 30% (higher socioeconomic position) and 45% (lower socioeconomic position). Conclusion: The risk of LTSA gradually increased with number of factors related to high physical work demands, underlining the importance of targeting combined factors in risk assessment and preventive interventions.

Associations between the workplace-effort in psychosocial risk management and the employee-rating of the psychosocial work environment - a multilevel study of 7565 employees in 1013 workplaces.

AIMS: This study examined the association between the workplace-effort in psychosocial risk management and later employee-rating of the psychosocial work environment. METHOD: The study is based on data from two questionnaire surveys - one including 1013 workplaces and one including 7565 employees from these workplaces. The association was analyzed using multi-level linear regression. The association for five different trade-groups and for five different psychosocial work environment domains was examined. RESULTS: Limited but statistically significant better employee-ratings of the psychosocial work environment in the respective domains were observed among Danish workplaces that prioritized "development possibilities for employees," "recognition of employees," "employees influence on own work tasks," good "communication at the workplace," and "help to prevent work overload." CONCLUSION: Danish workplaces with a high effort in psychosocial risk management in the preceding year had a small but significantly more positive rating of the psychosocial work environment by the employees. However, future studies are needed to establish the causality of the associations.

Contact allergy to preservatives in patients with occupational contact dermatitis and exposure analysis of preservatives in registered chemical products for occupational use.

PURPOSE: The aim of the study is to investigate risk factors for sensitization to preservatives and to examine to which extent different preservatives are registered in chemical products for occupational use in Denmark. METHODS: A retrospective epidemiological observational analysis of data from a university hospital was conducted. All patients had occupational contact dermatitis and were consecutively patch tested with 11 preservatives from the European baseline series and extended patch test series during a 5-year period: 2009-2013. Information regarding the same preservatives in chemical products for occupational use ('substances and materials') registered in the Danish Product Register Database (PROBAS) was obtained. RESULTS: The frequency of preservative contact allergy was 14.2% (n = 141) in 995 patients with occupational contact dermatitis. Patients with preservative contact allergy had significantly more frequently facial dermatitis (19.9 versus 13.1%) and age > 40 years (71.6 versus 45.8%) than patients without preservative contact allergy, whereas atopic dermatitis was less frequently observed (12.1 versus 19.8%). Preservative contact allergy was more frequent in painters with occupational contact dermatitis as compared to non-painters with occupational contact dermatitis (p < 0.001). This was mainly caused by contact allergy to methylisothiazolinone and contact allergy to formaldehyde. Analysis of the registered substances and materials in PROBAS revealed that preservatives occurred in several product categories, e.g., 'paints and varnishes', 'cleaning agents', 'cooling agents', and 'polishing agents'. Formaldehyde and isothiazolinones were extensively registered in PROBAS. CONCLUSIONS: The extensive use of formaldehyde and isothiazolinones in chemical products for occupational use may be problematic for the worker. Appropriate legislation, substitution, and employee education should be prioritized.

Difficulties in using Material Safety Data Sheets to analyse occupational exposures to contact allergens.

BACKGROUND: Information on the occurrence of contact allergens and irritants is crucial for the diagnosis of occupational contact dermatitis. Material Safety Data Sheets (MSDS) are important sources of information concerning exposures in the workplace. OBJECTIVE: From a medical viewpoint, to evaluate the information available from MSDSs, and to ascertain whether MSDS are easy to obtain, whether they serve their purpose, and whether they provide sufficient information regarding allergens to enable correct diagnosis. METHODS: MSDS and ingredients labelling were collected from consecutive patients and reviewed. If it was suspected that the MSDS were incomplete, the manufacturer, supplier, salesperson or workplace was contacted to gather more information. RESULTS: Twenty-five per cent (79/316) of patients provided material for the exposure assessment. One or more shortcomings were found in 18.6% (137/738) of the MSDS. The most frequent shortcoming was 'Missing R43/H317 while known contact allergen was present', which was observed in 63.1% (84/137). Other shortcomings were 'Names of preservatives not included in section 3 despite containing preservatives', in 48.9% (67/137), and 'Nothing about allergy in sections 2, 3, 11, 15 or 16 in the MSDS despite the content of allergens', in 20.4% (28/137). The information retrieved led to additional testing of 21 patients. CONCLUSION: Systematic exposure assessment is time-consuming. The main shortcomings are errors/omissions in the MSDS.

Exploring Environment-Intervention Fit: A Study of a Work Environment Intervention Program for the Care Sector.

Targeting occupational health and safety interventions to different groups of employees and sectors is important. The aim of this study was to explore the environment-intervention fit of a Danish psychosocial work environment intervention program for the residential and home care sector. Focus group interviews with employees and interviews with mangers were conducted at 12 selected workplaces and a questionnaire survey was conducted with managers at all 115 workplaces. The interventions enhanced the probability of employees experiencing more "good" work days, where they could make a difference to the lives of clients. The interventions may therefore be characterized as culturally compelling and having a good fit with the immediate work environment of employees. The interventions furthermore seemed to fit well with the wider organizational environment and with recent changes in the societal and economic context of workplaces. However, some workplaces had difficulties with involving all employees and adapting the interventions to the organization of work. The findings suggest that flexibility and a variety of strategies to involve all employees are important aspects, if interventions are to fit well with the care sector. The focus on employees' conceptualization of a "good" work day may be useful for intervention research in other sectors.

Occupational irritant contact dermatitis diagnosed by analysis of contact irritants and allergens in the work environment.

BACKGROUND: Irritant contact dermatitis (ICD) is a common diagnosis in patients with occupational contact dermatitis (OCD). Studies are lacking on the usefulness of material safety data sheets (MSDSs) in making the diagnosis of ICD. OBJECTIVE: To characterize irritant exposures leading to the diagnosis of occupational ICD (OICD), and to evaluate the occurrence of concomitant exposures to contact allergens. METHODS: We included 316 patients with suspected occupational hand dermatitis, referred to the Department of Dermato-Allergology, Copenhagen University Hospital Gentofte, Denmark during January 2010-August 2011, in a programme consisting of a clinical examination, exposure assessment, and extensive patch/prick testing. RESULTS: OCD was diagnosed in 228 patients. Of these patients, 118 were diagnosed with OICD. The main irritant exposures identified were wet work (n = 64), gloves (n = 45), mechanical traumas (n = 19), and oils (n = 15). Exposure to specific irritant chemicals was found in 9 patients, and was identified from MSDSs/ingredients labelling in 8 of these patients. Review of MSDSs and ingredients labelling showed that 41 patients were exposed to 41 moderate to potent contact allergens, and 18 patients were exposed to 25 weak workplace contact allergens. CONCLUSION: In the present study, the systematic exposure assessment did not reveal any new irritants. MSDSs have a limited role in the investigation of ICD.

Isothiazolinones in commercial products at Danish workplaces.

BACKGROUND: In recent years, a steep increase in the frequency of occupational contact allergy to isothiazolinones has been reported from several European countries. OBJECTIVE: To examine the extent and occurrence of isothiazolinones in different types of product at Danish workplaces. METHODS: Seven different isothiazolinones were identified in the Dictionary of Contact Allergens: Chemical Structures, Sources, and References from Kanerva's Occupational Dermatitis. By use of the chemical names and Chemical Abstracts Service numbers for these chemicals, information on products registered in the Danish Product Register Database (PROBAS) was obtained. RESULTS: All seven isothiazolinones were registered in PROBAS. The top three isothiazolinones registered were: benzisothiazolinone (BIT), registered in 985 products, methylisothiazolinone (MI), registered in 884 products, and methylchloroisothiazolinone (MCI)/MI, registered in 611 products. The concentration ranges were 0.01 ppm to 45% for BIT, 0.01 ppm to 10% for MI, and 0.01 ppm to 14.1% for MCI/MI. The most common product type was 'paint and varnish'; five of the seven isothiazolinones were registered in this type of product. CONCLUSION: Isothiazolinones are present in multiple products registered for use at workplaces, and may occur in high concentrations.

The association between health and sickness absence among Danish and non-Western immigrant cleaners in Denmark.

PURPOSE: The aim of the study is to investigate the association between health and sickness absence among Danish and non-Western immigrant cleaners in Denmark. METHODS: This study is based on a cross-sectional analysis of baseline data from 2007 to 2008. The study population includes 276 cleaners, 144 Danish and 132 non-Western immigrant cleaners. Cumulative sickness absences during a 6-month period from administrative records were subdivided into no sickness absence (0 days), low occurrence of sickness absence (1-10 days) and high occurrence of sickness absence (over 10 days). Measures of health consisted of self-report and objective assessments. The relationship between sickness absence and health was analyzed through multinomial logistic regression, stratified by immigrant status. RESULTS: For both Danish and non-Western immigrant cleaners, poor self-reported health was significantly related to high occurrence of sickness absence. Among Danish cleaners, high blood pressure was related to high occurrence of sickness absence. Among non-Western immigrant cleaners, total body pain and having one or more diagnosed chronic disease were related to high occurrence of sickness absence. No association between health and low occurrence of sickness absence was found. CONCLUSIONS: The findings confirm the importance of health for high occurrence of sickness absence, in both ethnic groups. Moreover, low occurrence of sickness absence was not related to the health conditions investigated.

Occupational allergic contact dermatitis diagnosed by a systematic stepwise exposure assessment of allergens in the work environment.

BACKGROUND: Information on the presence of contact allergens and irritants is crucial for the diagnosis of occupational contact dermatitis. Ingredient lists and Material Safety DataSheets (MSDSs) may be incomplete. OBJECTIVES: To evaluate the workability of a systematic exposure assessment in consecutive patients with suspected occupational contact dermatitis, and to study how it could potentially aid correct diagnostic classification. METHODS: A tool for systematic stepwise assessment of exposures in the work environment was developed, consisting of six steps spanning medical history and workplace visits. The programme included 228 consecutive patients diagnosed with occupational contact dermatitis; all patients underwent a clinical examination, the stepwise exposure assessment, and extensive patch and prick testing. RESULTS: Of the participants, 48.2% were classified as having occupational allergic contact dermatitis. The diagnosis was made at the stepwise exposure assessment for 50.0% of patients at Step 1 (medical history) and for 34.5% at Step 2 (ingredient labelling/MSDS). We found 132 different occupational allergens of relevance to the patients' eczema, of these, 78.0% were allergens not included in the European baseline series. CONCLUSIONS: Systematic stepwise exposure assessment provides information that results in the identification of occupational allergies caused by allergens not included in the European baseline series in a substantial number of patients.

Psychosocial work environment among immigrant and Danish cleaners.

INTRODUCTION: Non-Western cleaners have been shown to have poorer health than their Danish colleagues. One reason could be a poorer psychosocial work environment. However, it is unknown if differences in self-reported psychosocial work environment exist between non-Western and Danish workers within the same social class. The aim of this study was to investigate such differences among cleaners with the hypothesis that the non-Western compared with Danish cleaners would report a generally poorer psychosocial work environment. METHODS: Two hundred and eighty-five cleaners (148 Danes and 137 non-Western immigrants) from 9 workplaces in Denmark participated in this cross-sectional study. The cleaners' immigrant status was tested for association with psychosocial work environment scales from the short version of the Copenhagen Psychosocial Questionnaire (COPSOQ) using ordinal logistic regression. RESULTS: Models adjusted for age, sex, BMI, smoking, workplace, and perceived physical work exertion showed that non-Western cleaners compared with Danish cleaners reported significantly higher scores with regard to Predictability (OR = 3.97), Recognition (OR = 1.92), Quality of Leadership (OR = 1.81), Trust Regarding Management (OR = 1.72), and Justice (OR = 2.14). CONCLUSIONS: This study showed that non-Western immigrant cleaners reported a statistically significantly better psychosocial work environment than Danish cleaners on a number of scales. Therefore, the hypothesis of non-Western immigrants reporting worse psychosocial work environment than their Danish colleagues was not supported.
