“…GOLD criteria II+ was the most prevalent (92)(93)(94)(95). The FEV 1 and FEV 1 /FVC were the outcome in two studies (91,97), like FEV 1 /FVC<0.7 and <LLN (96,98). All eight studies found an association between airway obstruction/COPD and occupational exposure.…”

“…Five of these (91)(92)(93)(94)(95) were cross-sectional and three (96)(97)(98) were longitudinal with a follow-up time between 5-13 years. Six studies came from Europe (91,92,94,(96)(97)(98) and one study each from the US (93) and South Africa (95). Three of the studies (91,92,96) focused on inorganic exposure (cement production and metal melting), one (97) analyzed the association between organic exposure (dairy farming) and COPD, while four studies (93)(94)(95)98) were population-based.…”

“…JEM alone defined exposure in four studies (91,95,96,98); JEM with personal sampling technique was employed in one study (91), and JEM with questionnaire data in two studies (95,98). The exposure was solely characterized by self-report in three studies (93,94,97) and one study defined exposure by area sampling (92). The spirometric criteria included were non-uniform.…”

Occupational chronic obstructive pulmonary disease: a systematic literature review by Omland Ø, Würtz ET, Aasen TB, Blanc P, Brisman J, Miller MR, Pedersen OF, Schlünssen V, Sigsgaard T, Ulrik CS, Viskum S This review on occupational chronic obstructive pulmonary disease (COPD) addresses some of the potential limitations of earlier assessments by restricting the studies included to high quality epidemiological analysis involving only spirometrically confirmed air-flow obstruction as the outcome. The authors combined this with minimal requirements for exposure characterization allowing for analysis of population-based studies. Affiliation 19Review Scand J Work Environ Health. 2014;40(1):19-35. doi:10.5271/sjweh.3400 Occupational chronic obstructive pulmonary disease: a systematic literature review Objective Occupational-attributable chronic obstructive pulmonary disease (COPD) presents a substantial health challenge. Focusing on spirometric criteria for airflow obstruction, this review of occupational COPD includes both population-wide and industry-specific exposures.Methods We used PubMed and Embase to identify relevant original epidemiological peer-reviewed articles, supplemented with citations identified from references in key review articles. This yielded 4528 citations. Articles were excluded for lack of lung function measurement, insufficient occupational exposure classification, lack of either external or internal referents, non-accounting of age or smoking effect, or major analytic inadequacies preventing interpretation of findings. A structured data extraction sheet was used for the remaining 147 articles. Final inclusion was based on a positive qualitative Scottish Intercollegiate Guidelines Network (SIGN) score (≥2+) for study quality, yielding 25 population-wide and 34 industry/occupation-specific studies, 15 on inorganic and 19 on organic dust exposure, respectively. ResultsThere was a consistent and predominantly significant association between occupational exposures and COPD in 22 of 25 population-based studies, 12 of 15 studies with an inorganic/mineral dust exposure, and 17 of 19 studies on organic exposure, even though the studies varied in design, populations, and the use of measures of exposure and outcome. A nearly uniform pattern of a dose-response relationship between various exposures and COPD was found, adding to the evidence that occupational exposures from vapors, gas, dust, and fumes are risk factors for COPD. ConclusionThere is strong and consistent evidence to support a causal association between multiple categories of occupational exposure and COPD, both within and across industry groups.Key terms: airflow obstruction; COPD; dust; fume; gas; lung function measurement; occupational exposure; vapor. Chronic obstructive pulmonary disease (COPD) represents serious morbidity and has emerged as a leading cause of death worldwide (1). Although tobacco smoking is the leading factor in the etiology of COPD, the disease may be caused by inhalation of different gases and aerosols among bot...

“…Thus, all of these populations are exposed to wheat dust. Moreover, work-related respiratory effects have been proved, even after the 2000s, in terminal elevator operators [4], livestock and dairy farmers [2,5,9,10,11,12], and grain farmers [13], by epidemiological studies conducted on these populations. However, no data are available on populations of harvesters and straw ball makers, mainly because they are only seasonally exposed to wheat.…”

Introduction. Occupational exposure to grain dust causes respiratory symptoms and pathologies. To decrease these effects, major changes have occurred in the grain processing industry in the last twenty years. However, there are no data on the effects of these changes on workers' respiratory health. Objectives. The aim of this study was to evaluate the respiratory health of grain workers and farmers involved in different steps of the processing industry of wheat, the most frequently used cereal in Europe, fifteen years after major improvements in collective protective equipment due to mechanisation. Materials and Method. Information on estimated personal exposure to wheat dust was collected from 87 workers exposed to wheat dust and from 62 controls. Lung function (FEV 1 , FVC, and PEF), exhaled nitrogen monoxide (F E NO) and respiratory symptoms were assessed after the period of highest exposure to wheat during the year. Linear regression models were used to explore the associations between exposure indices and respiratory effects. Results. Acute symptoms -cough, sneezing, runny nose, scratchy throat -were significantly more frequent in exposed workers than in controls. Increased mean exposure level, increased cumulative exposure and chronic exposure to more than 6 mg.m -3 of inhaled wheat dust were significantly associated with decreased spirometric parameters, including FEV 1 and PEF (40 ml and 123 ml.s
