Abstract
To investigate occupational risks of lung adenocarcinoma in Uruguay and to confirm a previously reported increased risk among butchers. We conducted a case-control study among men in four major hospitals in Montevideo, based on interviews to 338 cases of lung adenocarcinoma and 1014 hospital-based controls. We calculated odds ratios (ORs) of lung adenocarcinoma for employment in 22 jobs, after adjustment for tobacco smoking and other potential confounders. The OR was increased for employment as farmer, tractor driver, painter and medical worker, but no trend was suggested for duration of employment. Long-term employment as mason, glass worker or textile worker resulted in an increased OR. The OR for employment as butcher was 1.2 (95% confidence interval 0.7-2.1). The OR increased with increasing duration of self-reported exposure to formaldehyde. Occupational exposures seem to play a limited role in causing lung adenocarcinoma among men in Uruguay. Employment as butcher was not confirmed as an important risk factor.
