BackgroundExposure to cooking fumes may have different deleterious effects on the respiratory system. The aim of this study was to look at possible effects from inhalation of cooking fumes on pulmonary function.MethodsTwo groups of 12 healthy volunteers (A and B) stayed in a model kitchen for two and four hours respectively, and were monitored with spirometry four times during twenty four hours, on one occasion without any exposure, and on another with exposure to controlled levels of cooking fumes.ResultsThe change in spirometric values during the day with exposure to cooking fumes, were not statistically significantly different from the changes during the day without exposure, with the exception of forced expiratory time (FET). The change in FET from entering the kitchen until six hours later, was significantly prolonged between the exposed and the unexposed day with a 15.7% increase on the exposed day, compared to a 3.2% decrease during the unexposed day (p-value = 0.03). The same tendency could be seen for FET measurements done immediately after the exposure and on the next morning, but this was not statistically significant.ConclusionIn our experimental setting, there seems to be minor short term spirometric effects, mainly affecting FET, from short term exposure to cooking fumes.
PurposeNorwegian 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. MethodsWe 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. ResultsOverall, 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 % C.I.: 1.2 -5.3). Using gas for frying and using a fryer in the kitchen were also related to the occurrence of respiratory complaints.3 ConclusionsThis 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.
Objectives: Cooks have increased morbidity and mortality. A high turnover has also been reported. We aimed to elucidate work environment and work sustainability in Norwegian cooks. Material and Methods: A questionnaire inquiring about working conditions and work participation was sent to 2082 cooks who had qualified from 1988 onwards. Of these, 894 responded. Time at work was analyzed with Kaplan-Meier plots and possible determinants for quitting work as a cook was analyzed with Cox regression. Results: The median time at work was 16.6 years. There were differences in sustainability between types of kitchens for both sexes (p = 0.00). The median time in the profession was 9.2 years for the cooks in restaurants, while the cooks in institutions and canteens showed a substantially higher sustainability with 75.4% still at work after 10 years, and 57% still at work after 20 years in the profession. Of those still at work as a cook, 91.4% reported a good or very good contentment, and the 67.4% who expected to stay in the profession the next 5 years frequently answered that excitement of cooking, the social working environment, and the creative features of cooking were reasons to continue. Musculoskeletal complaints were the most common health-related reason for leaving work as a cook, while working hours was the most common non-health-related reason. Conclusions: There are significant differences in work sustainability between the cooks in the different types of kitchens. The identified determinants for length of time in the occupation can be used for preventive purposes.
