To investigate whether Chinese restaurant waiters in Hong Kong had an incre
ased risk of dying from colorectal cancer, we linked the records of decease
d union members to the mortality information for the general population bet
ween 1986 and 1995. A case-control analysis among the deceased was performe
d with 346 deceased waiters and 306 deceased male kitchen workers. Waiters
were found to have a significantly higher mortality odds ratio [(MOR) 2.29;
95% confidence interval (Cl) = 1.47-3.56] of colorectal cancer when compar
ed with the general population. The MOR (1.45; 95% Cl = 0.71-2.93) was incr
eased, but not significantly, when compared with the kitchen workers. The s
tudy suggested that waiters in Hong Kong Chinese restaurants are at a highe
r risk of dying from colorectal cancer. An unhealthy diet associated with t
heir job is a possible explanation, and interventions should be initiated.
