RT Journal Article SR Electronic T1 The risk of hospitalisation for infectious pneumonia in mineral dust exposed industries JF Occupational and Environmental Medicine JO Occup Environ Med FD BMJ Publishing Group Ltd SP 116 OP 119 DO 10.1136/oem.2009.051334 VO 68 IS 2 A1 Dong-Hee Koh A1 Ki-Tae Moon A1 Jeong-Youn Kim A1 Seong-Weon Choe YR 2011 UL http://oem.bmj.com/content/68/2/116.abstract AB Objectives The purpose of the study was to elucidate the relationship between industries characterised by mineral dust exposure and infectious pneumonia.Methods The authors applied a retrospective record linkage design and used the nationwide specific health examination database and identified industries where mineral dust exposure occurs and a control group composed of workers who had been exposed to noise-only during a 2000–2004 period. The database was matched with National Health Insurance claim records to identify pneumonia admissions from 2000 to 2005. The indirectly standardised admission ratios (SARs) for pneumonia admissions were estimated by comparing mineral dust exposed industry workers with noise-only exposed workers.Results The authors found significantly elevated SARs in both men (1.54, 95% CI 1.13 to 2.05) and women (3.23, 95% CI 1.40 to 6.37) working in the cement, lime, plaster and plaster products industries, and only in men working in the cast-metals industry (foundry) (1.64, 95% CI 1.25 to 2.11).Conclusions These results support the association between mineral dust exposure, as well as metal fumes, and infectious pneumonia.
