To investigate lung cancer risk, the authors conducted a historical cohort mortality study of 4,459 mild steel welders who had been employed at three midwestern plants which manufactured heavy equipment.
Follow-up began in the mid-1950s and extended through 1988.
All welders had at least 2 years welding experience (average duration, 8.5 years).
This cohort had no occupational exposure to asbestos or stainless steel fumes (containing nickel and chromium), two potential confounders in previous welders studies.
A comparison population of 4,286 nonwelders, all with at least 2 years employment at the same plants, was also studied.
Nonwelders had never been welders and were allowed to have no more than 90 days employment as a painter, foundryman, or machinist.
