Abstract To elucidate the subjective thermal strain of workers in kitchen working environments, a cross-sectional study involving 991 workers in 126 kitchen facilities in Japan was performed, using a self-reporting questionnaire survey and subjective judgment scales (SJS). The ambient temperature, mean radiant temperature (MRT), and wet-bulb globe temperature (WBGT) index were measured in 10 kitchen facilities among the 126 kitchens. The association of SJS with the types of kitchen was estimated by multiple logistic regression models. Of the 991 kitchen workers, 809 (81%) responded to the questionnaire survey. Compared with electric kitchens, the proportion of workers who perceived the room temperature as hot to very hot was significantly higher, and the ambient temperature, MRT and WBGT were significantly higher in gas kitchens. Compared with electric kitchens, workers in gas kitchens had a more than fivefold (males) and tenfold (females) higher SJS adjusted for confounding factors (male odds ratio (OR), 5.13 and female OR 10.9). Although SJS was affected by some confounding factors, the results suggest that workers in gas kitchens might be exposed to a higher heat strain than those in electric kitchens.
