We have used data from three analyses of occupational mortality for England and Wales to investigate a suspected hazard of pneumonia in welders.
Mortality from the disease was consistently raised in welders aged 15-64, with standardised mortality ratios of 184 (95% CI 150-224) in 1959-63 and 157 (121-200) in 1970-72.
Analysisofdata for 1979-80 and 1982-90 showed that the increased risk is attributable mainly to an excess of pneumococcal and unspecified lobar pneumonia (proportional mortality ratio 255,95% CI 192-332).
No excess occurred in men above retirement age (65).
A possible explanation of these findings is that welding fume reversibly increases the susceptibility of the lung to pneumonic infection.
