Change in Lung Function over Time in Male Metropolitan Firefighters and General Population Controls: A 3-year Follow-up Study
[Objectives]: Previous studies in firefighters have been contradictory regarding their course of lung function over time. The aim of this ongoing study is to investigate how changes in lung function over time in male metropolitan firefighters compare with those in population controls, and to explore...

| description | [Objectives]: Previous studies in firefighters have been contradictory regarding their course of lung function over time. The aim of this ongoing study is to investigate how changes in lung function over time in male metropolitan firefighters compare with those in population controls, and to explore associations between firefighters' use of personal respiratory protection devices during occupational exposures and their risk of accelerated lung function decline. [Methods]: A prospective comparison of FEV1 (forced expiratory volume in 1 second) and FVC (forced vital capacity) was performed between 281 firefighters and 933 population controls. Logistic regression models were used to compare changes from baseline of FEV1 and FVC after 3 years and risk of accelerated decline between the cohorts. Within the firefighter cohort, risk of accelerated decline was compared between subgroups based on use of respiratory protection devices. [Results]: Controls showed similar mean annual declines for FEV1 and FVC across age categories, whereas firefighters aged |

Firefighters had a lower odds of accelerated FEV1 decline compared with controls (OR=0.60, 95%Cl 0.44; 0.83), but firefighters who never or rarely used respiratory protection during fire knockdown had a higher odds of accelerated FEV1 decline compared with those who used it often or frequently (OR=2.20, 95%Cl 1.02; 4.74). [Conclusions]: Younger generations of firefighters showed an increase in lung function relative to older colleagues, while population controls consistently showed decline of lung function across all ages. Firefighters who reported to be incompliant in using respiratory protection showed an increased risk of accelerated FEV1 decline.</description><identifier>ISSN: 1341-9145</identifier><identifier>ISSN: 1348-9585</identifier><identifier>EISSN: 1348-9585</identifier><identifier>DOI: 10.1539/joh.12-0189-OA</identifier><identifier>PMID: 23796594</identifier><language>eng</language><publisher>Australia: JAPAN SOCIETY FOR OCCUPATIONAL HEALTH</publisher><subject>Adult ; Aged ; Firefighters ; Follow-Up Studies ; Forced Expiratory Volume - physiology ; Humans ; Logistic Models ; Male ; Middle Aged ; Occupational Diseases ; Occupational Exposure - adverse effects ; Prospective Studies ; Protective Devices ; Respiratory Function Tests ; Smoking/adverse effects ; South Australia ; Urban Population ; Vital Capacity - physiology</subject><ispartof>Journal of Occupational Health, 2013-07, Vol.55 (4), p.267-275</ispartof><rights>2013 Japan Society for Occupational Health</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c6275-b693875e3898473075b52fe03030ba0d4711b5ca41a7d450673c118afa6a66b3</citedby><cites>FETCH-LOGICAL-c6275-b693875e3898473075b52fe03030ba0d4711b5ca41a7d450673c118afa6a66b3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1539%2Fjoh.12-0189-OA$$EPDF$$P50$$Gwiley$$H</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1539%2Fjoh.12-0189-OA$$EHTML$$P50$$Gwiley$$H</linktohtml><link.rule.ids>314,778,782,1414,27911,27912,45561,45562</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/23796594$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Schermer, Tjard R.</creatorcontrib><creatorcontrib>Malbon, Winifred</creatorcontrib><creatorcontrib>Adams, Robert</creatorcontrib><creatorcontrib>Morgan, Michael</creatorcontrib><creatorcontrib>Smith, Michael</creatorcontrib><creatorcontrib>Crockett, Alan J.</creatorcontrib><creatorcontrib>Radboud University Nijmegen Medical Centre</creatorcontrib><creatorcontrib>The University of Adelaide</creatorcontrib><creatorcontrib>The Queen Elizabeth Hospital Campus</creatorcontrib><creatorcontrib>School of Health Sciences</creatorcontrib><creatorcontrib>Discipline of Medicine</creatorcontrib><creatorcontrib>Department of Primary and Community Care</creatorcontrib><creatorcontrib>Discipline of General Practice</creatorcontrib><creatorcontrib>Health Observatory</creatorcontrib><creatorcontrib>School of Population Health</creatorcontrib><creatorcontrib>South Australian Metropolitan Fire Service</creatorcontrib><creatorcontrib>Adelaide Fire Station</creatorcontrib><creatorcontrib>University of South Australia</creatorcontrib><title>Change in Lung Function over Time in Male Metropolitan Firefighters and General Population Controls: A 3-year Follow-up Study</title><title>Journal of Occupational Health</title><addtitle>J Occup Health</addtitle><description>[Objectives]: Previous studies in firefighters have been contradictory regarding their course of lung function over time.
