Abstract

Objectives: Cooking oil fumes (COFs) contain many carcinogens. We investigated the association between COFs and incidence risk of any cancer and lung cancer in chefs.

Methods: We identified Chinese food chefs and non-Chinese food chefs from Taiwan's national database of certified chefs in 1984-2007. Of them, 379,275 had not been diagnosed as having any cancer before chef certification. We followed them in Taiwan's Cancer Registry Database (1979-2010) and Taiwan's National Death Statistics Database (1985-2011) for any newly diagnosed cancer or lung cancer.

Results: 378,126 and 379,215 chefs were included for risk analysis of cancer and lung cancer, respectively. 6099 chefs developed cancer and 339 developed lung cancer over the follow-up periods of 4,183,550 and 4,220,163 person-years, respectively. Compared to non-Chinese food chefs, the adjusted IRR of cancer for Chinese food chefs was 1.69 (95% CI 1.51-1.89). For lung cancer, the risk was significantly higher among Chinese food chefs who had been certified for more than 5 years (adjusted IRR 2.12, 95% CI 1.32-3.40). This increased risk was pronounced in female chefs (adjusted IRR 4.73, 95% CI 1.74-12.86).

Conclusions: Chinese food chefs had an increased risk of cancer and lung cancer, particularly in females.

Keywords: Cooking oil fumes; Gender; Lung cancer; Occupational chefs.
