abstract = {Objective Heat exposure and heat stress/strain is a concern for many workers. There is increasing interest in
potential chronic health effects of occupational heat exposure, including cancer risk. We examined potential
associations of occupational heat exposure and colorectal cancer (CRC) risk in a large Spanish multi-case–control
study.
Methods We analyzed data on 1198 histologically confirmed CRC cases and 2690 frequency-matched controls.
The Spanish job-exposure matrix, MatEmEsp, was used to assign heat exposure estimates to the lifetime occupations
of participants. Three exposure indices were assessed: ever versus never exposed, cumulative exposure and
duration (years). We estimated odds ratios (OR) and 95% confidence intervals (CI) using unconditional logistic
regression adjusting for potential confounders.
Results Overall, there was no association of ever, compared with never, occupational heat exposure and CRC
(OR 1.09, 95% CI 0.92–1.29). There were also no associations observed according to categories of cumulative
exposure or duration, and there was no evidence for a trend. There was no clear association of ever occupational
heat exposure and CRC in analysis conducted among either men or women when analyzed separately. Positive
associations were observed among women in the highest categories of cumulative exposure (OR 1.81, 95% CI
1.09–3.03) and duration (OR 2.89, 95% CI 1.50–5.59) as well as some evidence for a trend (P<0.05).
Conclusion Overall, this study provides no clear evidence for an association between occupational heat exposure
and CRC.},
