A mortality study of newspaper printing workers

Area of Science:

• Occupational Health
• Epidemiology
• Environmental Medicine

Background:

• A mortality study was initiated following worker concerns about high cancer rates at a Milan newspaper plant.
• The study period spanned two decades, from 1956 to 1975, encompassing a significant cohort of workers.

Purpose of the Study:

• To investigate the reported high incidence of cancer and overall mortality among newspaper plant workers.
• To identify specific job roles and potential contributing factors associated with observed mortality patterns.

Main Methods:

• A retrospective mortality study involving 700 workers with a total of 12,198 person-years.
• Analysis of overall mortality, cancer mortality, and deaths from circulatory diseases, stratified by age and job category.

Main Results:

• Overall mortality was not lower than expected, with a significant excess in the 25-54 age group.
• Elevated cancer mortality, specifically lung cancer, was observed among packers and forwarders.
• Increased mortality from circulatory diseases and ischemic heart disease was linked to age, employment duration, and job role (packers and forwarders).

Conclusions:

• Newspaper production workers, especially packers and forwarders, face elevated risks for cancer and cardiovascular diseases.
• Occupational exposures and lifestyle factors within the newspaper industry may explain the observed mortality patterns.
• Further investigation into specific workplace exposures and personal habits is warranted to mitigate health risks.
