Background Shipbreaking workers are typically exposed to a wide range of hazardous
chemicals. However, long-term follow-up studies of their mortality patterns are
lacking. This study examined mortality among shipbreaking workers over a 24-year
follow-up period.

Methods A total of 4,962 shipbreaking workers were recruited from the database of
the Kaohsiung Shipbreaking Workers Union. The data were then linked to the Taiwan
National Death Registry from 1985 to 2008. The mortality ratios—standardized for
age and calendar years—(SMRs) for various causes of deaths were calculated with
reference to the general population of Taiwan.

Results Among men workers, a statistically significant increased SMR was observed
for all causes (SMR ¼ 1.28), all cancers (SMR ¼ 1.26; particularly noteworthy for
lesions of oral and nasopharyngeal: SMR 2.03, liver: SMR 4.63, and lung: SMR 1.36),
cirrhosis of the liver (SMR ¼ 1.32), and accidents (SMR ¼ 1.91). A statistically significant
increase in mortality was observed for respiratory system cancer
(SMR ¼ 1.87) and lung cancer (SMR ¼ 1.91) among workers with a longer duration
of employment (7 years). The result also showed that among shipbreaking workers
who were still alive, two people had mesothelioma and 10 people have asbestosis.

Conclusions Those employed in shipbreaking industries experienced an increase in
mortality from all causes. The increased SMR for lung cancer was probably related to
asbestos, metals, and welding fume exposure. Am. J. Ind. Med. 56:701–708, 2013.
