Absences attributed to respiratory diseases in welders

Area of Science:

• Occupational Health
• Environmental Medicine
• Respiratory Medicine

Background:

• Occupational exposure to welding fumes is a concern in industrial settings.
• Understanding the health impacts of welding on respiratory systems is crucial for worker safety.

Purpose of the Study:

• To investigate the sickness rates among male welders compared to a matched control group.
• To analyze the impact of welding on respiratory disease severity, duration, and frequency.

Main Methods:

• A cohort study comparing 36 male welders with 36 matched male controls from a petrochemical plant (1970-1979).
• Analysis of certified sickness rates, including severity, duration, and frequency of all diseases and specifically respiratory diseases.
• Comparison of sickness rates between smokers and non-smokers within the welders and control groups.

Main Results:

• Welders showed slightly higher severity, duration, and frequency of respiratory disease absences compared to controls.
• The proportion of days lost due to respiratory diseases was 2.3 times higher in welders.
• Absences due to lower respiratory tract diseases were significantly higher in welders (over four to one ratio for severity and inception rate).
• Smokers exposed to welding fumes were more affected than non-smokers.

Conclusions:

• Welding activities are associated with an increased risk of respiratory diseases, particularly lower respiratory tract conditions.
• Smoking exacerbates the negative respiratory health effects of welding fume exposure.
• Implementing stricter occupational health measures for welders, especially smokers, is recommended.
