To clarify the correlation between kitchen work-related burns and cuts and job stress, a
self-administered questionnaire survey was conducted involving 991 kitchen workers among
126 kitchen facilities. The demographics, condition of burns and cuts, job stress with the
Brief Job Stress Questionnaire (BJSQ), health condition, and work-related and
environmental factors were surveyed. Multiple logistic regression models and trend tests
were used according to quartiles (Q1, Q2, Q3, and Q4) of each sub-scale BJSQ. After
adjustment for potential confounding variables, burns/cuts were associated with a higher
score category (Q4) of job demands (OR: 2.56, 95% CI: 1.10–6.02/OR: 2.72, 95% CI:
1.30–5.69), psychological stress (OR: 4.49, 95% CI: 2.05–9.81/OR: 3.52, 95% CI:
1.84–6.72), and physical stress (OR: 2.41, 95% CI: 1.20–4.98/OR 2.16, 95% CI: 1.16–4.01).
The ORs of the burn/cut injures increased from Q1 to Q4 with job demands
(p for trend = 0.045/0.003), psychological stress
(p for trend<0.001/0.001), and physical stress
(p for trend = 0.006/0.005), respectively. These
findings suggest that kitchen work-related burns and cuts are more likely to be correlated
with job stress, and the higher the job stress score, the higher the frequency of burns
and cuts among kitchen workers.
