Purpose: Norwegian cooks exhibit relatively high mortality, particularly from respiratory diseases. Both occupational hazards and lifestyle factors have been suggested as possible explanations. Negative health effects from exposure to cooking fumes are well documented in non-Western populations, and it has been claimed that cooking fumes in Western style cooking might be substantially different. We hypothesise that exposure to cooking fumes contributes to respiratory diseases also in professional cooks in Western countries. The aim of this study was to elucidate if specific work environment factors related to cooking fume exposure are determinants for respiratory morbidity in Norwegian cooks. Methods: We surveyed specific work environment factors and respiratory complaints in 553 subjects that were currently working as skilled cooks. Inclusion was based on the register of people that had graduated as skilled cooks in central Norway between 1988 and 2008. Determinants for the occurrence of respiratory complaints were explored by logistic regression. Results: Overall, 17.2% of subjects reported respiratory complaints at work, while 8.1% had chronic bronchitis. Those who performed frying for over half of their workday exhibited an increased odds ratio for having chronic bronchitis of 2.5 (95% CI 1.2–5.3). Using gas for frying and using a fryer in the kitchen were also related to the occurrence of respiratory complaints. Conclusions: This study in Norwegian cooks demonstrates a relationship between the extent of frying and the occurrence of work-related respiratory complaints. Therefore, reducing exposure to cooking fumes could reduce respiratory complaints in cooks, and potentially help alleviate excess morbidity and mortality in this occupation. [ABSTRACT FROM AUTHOR]

Purpose: Development of neck pain (NP) in workers has a multifactorial etiology and depends on both individual and workplace factors. The aim of this study was to investigate risk factors for episodic NP in a large diverse sample of active workers.Methods: A prospective study based on the surveillance program implemented by the French Public Health Agency in the Loire Valley region. Between 2002 and 2005, 3710 workers were included. Between 2007 and 2010, 2332 workers responded to a follow-up questionnaire which assessed: (1) musculoskeletal symptoms (Nordic questionnaire) and (2) individual and work-related risk factors. Associations between episodic NP in 2007 (i.e., free subjects at baseline and who suffered at least 8 days during the preceding 12 months) and individual and work-related risk factors at baseline were studied using logistic regression modeling, stratified by sex.Results: Among the 1510 workers (914 men, 596 women) still active at follow-up, 10.4% (8.4-12.4) of men and 14.6% (11.8-17.4) of women declared episodic NP. Among men, work pace dependence of guests or permanent hierarchical controls were risk factors of NP [OR = 1.8 (1.1-2.8) and OR = 2.1 (1.3-3.3), respectively]. Among women, the combination of sustained/repeated arm abduction with high physical perceived exertion was the strongest risk factor for NP [OR = 3.5 (1.7-7.2)]; age and paced work were also predictors for NP in women.Conclusions: NP results from complex relationships between individual and work-related variables. High physical workload, awkward postures, and poor organizational environment together with age differently predicted episodic NP according to the sex. [ABSTRACT FROM AUTHOR]

Objective: Develop a model to predict the prevalence of lower limb pain using indicators of high workplace exposures based on the fifth European Working Conditions Survey, evaluate its impact and explore its significance for work-related health problems. Method: Cross-sectional interview data of 35,372 workers from 27 countries of the European Union in 2010 (EU27) were used to develop (20% sample) and validate (80% sample) a logistic regression model for lower limb pain. Independent variables included descriptions of working conditions, assessments of physical and psychosocial exposures at work, and demographic factors. The impact of the model was explored through the amount of lower limb pain cases attributable to work and estimating work absences correlated with lower limb pain. Results: The resulting logistic model included ten risks indicators and one preventive factor. The highest odds ratios (OR) corresponded to 'tiring or painful positions' OR 2.0, 99% confidence interval (99% CI) 1.9-2.2, and 'not satisfied with level of working conditions in the job' (OR 1.6, 99% CI 1.5-1.7). The prevalence of work-related lower limb pain was 16.5% for men and 15.8% for women for the 27 countries of the European Union. Estimates based on the developed model revealed more than 34 million cases of work-related lower limb pain, where four physical risks explained about 22 million cases. In addition, more than 3 million days of absence from work in 2010 could be attributed to lower limb pain. Conclusion: Lower limb pain is highly prevalent among the European workforce and work exposures are a major contributing factor. Effective workplace interventions should aim at improving working conditions at workplaces with multiple risks. [ABSTRACT FROM AUTHOR]

Purpose: Exacerbation is a critical event in asthma management. We investigated whether exacerbation of symptoms is associated with farming exposures among agricultural pesticide applicators with asthma. Methods: Participants were pesticide applicators with active asthma (wheezing and breathing problems in past 12 months) who completed enrollment questionnaires for the Agricultural Health Study (AHS). Exacerbation of asthma was defined as having visited a hospital emergency room or doctor for an episode of wheezing or whistling in the past 12 months. Exposures of interest were using 36 specific pesticides in the past 12 months and conducting various agricultural activities. Adjusted odds ratios (ORs) were estimated by logistic regression while controlling for potential confounders. Results: The 926 AHS adult pesticide applicators with active asthma included 202 (22 %) with exacerbation. Inverse associations with exacerbation were observed for two herbicides [glyphosate, odds ratio (OR) = 0.5, 95 % confidence interval (CI) 0.3, 0.8, and paraquat, OR = 0.3, 95 % CI 0.1, 0.9] and several agricultural activities (repairing engines, grinding metal, driving diesel tractors, and performing veterinary procedures). Only asthma cases with allergies (i.e., doctor-diagnosed hay fever or eczema, 46 %) had positive exacerbation-pesticide associations, with OR = 2.1 (95 % CI 1.1, 4.1) for the herbicide pendimethalin and OR = 10.2 (95 % CI 1.9, 55) for the insecticide aldicarb. Conclusions: The inverse associations with two pesticides and specific farm activities are consistent with the possibility that asthma cases prone to exacerbation may avoid exposures that trigger symptoms. Although limited by small sample size and a cross-sectional design, our study suggests that use of specific pesticides may contribute to exacerbation of asthma among individuals with allergies.

Objectives: Musculoskeletal pain conditions remain a major cause of care-seeking in general practice. Not all patients with musculoskeletal pain (MP) seek care at their general practitioner (GP), but for those who do, the GP's knowledge of what work-related factors might have influenced the patient's decision to seek care could be important in order to give more well-founded advice to our patients. The objective of this study was to elucidate the effects of workloads on care-seeking for back pain or upper extremity pain during an eighteen-month follow-up period. Methods: This is a prospective study with a baseline questionnaire and eighteen-month follow-up. Among the registered patients of 8 GPs, we identified 8,517 persons between 17 and 65 years of age, who all received the questionnaire. A total of 5,068 (59.5 %) persons answered. During the eighteen months of follow-up, we used the International Classification for Primary Care (ICPC) to identify all care-seekers with either back pain or upper extremity pain. Of these, all currently employed persons were included in our analysis, in all 4,325 persons. For analysis, we used Cox proportional hazards regression analysis. Analyses were stratified by gender. Results: High levels of heavy lifting, defined as the upper tertile on a categorical scale, were associated with care-seeking for back pain (HR 1.90 [95 % CI: 1.14-3.15]) and upper extremity pain (HR 2.09 [95 % CI: 1.30-3.38]) among males, but not in a statistically significant way among females. Repetitive work and psychosocial factors did not have any statistically significant impact on care-seeking for neither back pain nor upper extremity pain. Conclusion: Work-related factors such as heavy lifting do, to some extent, contribute to care-seeking with MP. We suggest that asking the patient about physical workloads should be routinely included in consultations dealing with MP. [ABSTRACT FROM AUTHOR]

Objective Reports on the aetiology and risk of occupational rhinitis in different occupations are scarce. Method: The purpose of this study was to find the occupations with an increased risk of occupational rhinitis. Age and gender differences in occupational rhinitis and occupational asthma were also compared, and the most common causes of occupational rhinitis were analysed. Design: This study covered the cases of occupational rhinitis and asthma reported to the Finnish Register of Occupational Diseases during the years 1986–1991. The cases on the Register were linked to the longitudinal census data file from the Finnish censuses. Results: During 1986–1991, 1244 new cases of occupational rhinitis (747 women and 497 men) and 1867 new cases of occupational asthma (916 women and 951 men) were reported to the Register. Animal dander, flours, wood dusts, textiles, phthalic acid anhydrides and storage mites were important causes of occupational rhinitis. The highest relative risk of occupational rhinitis was among furriers, the age-standardized rate ratio (SRR) was 30.0. Bakers and livestock breeders had also a markedly elevated relative risk (SRR=22.0). Men had the highest incidence of occupational rhinitis at the age of 25–29 years and among women the incidence gradually increased and reached the peak in the group 40–44 years of age. Conclusion: Furriers, bakers, and livestock breeders had the most elevated relative risk of occupational rhinitis. Occupational rhinitis cases appeared at a younger age than asthma, suggesting that rhinitis often precedes asthma. [ABSTRACT FROM AUTHOR]
