- It has previously been shown that occupational exposure limits (OELs) for the same substance can vary significantly between different standard-setters. The work presented in this paper identifies the steps in the process towards establishing an OEL and how variations in those processes could account for these differences. This study selects for further scrutiny substances for which the level of OELs vary by a factor of 100, focussing on 45 documents concerning 14 substances from eight standard-setters. Several of the OELs studied were more than 20 years old and based on outdated knowledge. Furthermore, different standard-setters sometimes based their OELs on different sets of data, and data availability alone could not explain all differences in the selection of data sets used by standard-setters. While the interpretation of key studies did not differ significantly in standard-setters' documentations, the evaluations of the key studies' quality did. Also, differences concerning the critical effect coincided with differences in the level of OELs for half of the substances.

Work and excessive sleepiness among Brazilian evning high school students : Effects on Days Off
- 2010

Tidskriftsartikel (refereegranskat)abstract
- Previous studies have revealed that students who work and study build up sleep deficits during the workweek, which can trigger a sleep rebound during days off. The objective of this study was to investigate the impact of working/non-working on sleepiness during days off among high school students. The study population, aged 14-21 years, attended evening classes in São Paulo, Brazil. For the study, the students completed questionnaires on living conditions, health, and work; wore actigraphs; and completed the Karolinska Sleepiness Scale (KSS). To predict sleepiness, a logistic regression analysis was performed. Excessive sleepiness was observed on the first day off among working students. Results suggest that working is a significant predictor for sleepiness and that two shifts of daily systematic activities, study and work, might lead to excessive daytime sleepiness on the first day off. Further, this observed excessive sleepiness may reflect the sleep debt accumulated during the workweek

Tidskriftsartikel (refereegranskat)abstract
- A cohort of 1,220 farmers, 1,130 nonfarming rural men, and 1,087 urban referents from Sweden were monitored for 12 years. Farmers had lower mortality than urban referents for all causes of death (hazard ratio [HR] = 0.51; 95% confidence interval [CI], 0.37-0.71), cancer (HR = 0.44; 95% CI, 0.24-0.78) and cardiovascular diseases (HR = 0.60; 95% CI, 0.36-0.99). Nonfarming rural men had lower mortality than urban referents for all causes of deaths (HR = 0.81; 95% CI, 0.70-0.94). Farmers and nonfarming rural men had significantly lower morbidity risks of cancer and of psychiatric disorders than urban referents. Farmers had significantly lower risk of endocrine disorders, cardiovascular disorders, and respiratory disorders. In general, morbidity was lower among nonfarming rural men compared with urban referents and was even lower among farmers. Urban referents had, however, significantly less musculoskeletal disorder morbidity. An urban-rural factor and a farming occupational or lifestyle factor results in lower mortality and morbidity rates except concerning musculoskeletal disorders.
