Occupational Burden of Chronic Obstructive Pulmonary Disease in the Commonwealth of Independent States: Systematic Review and Meta-Analysis

Abstract

Background: Population-based studies from the Russian Federation and neighboring countries on the occupational burden of chronic obstructive pulmonary disease (COPD) are seldom or not included in the systematic reviews. The aim of this review was to summarize published population-based studies from the Commonwealth of Independent States (CIS) in order to ascertain the occupational burden of COPD.Methods: We systematically searched www.elibrary.ru and PubMed for population-based studies on the epidemiology of COPD in nine countries using PRISMA. Quality of studies was assessed using the original tool. The odds of COPD in the included studies from vapors, gases, dusts, and fumes (VGDF) was pooled using meta-analysis (fixed effects model), whereas the population attributable fraction percent (PAF%) was pooled with meta-proportion using the random effects model in Stata 14.2.Results: Five studies, three from Russia, one from Kazakhstan, and one more from Azerbaijan and Kazakhstan (total N = 18,908) with moderate to high quality and published from 2014 to 2019 (none from Armenia, Belarus, Kyrgyzstan, Moldova, Tajikistan, and Uzbekistan), were included. Spirometry-defined COPD was the outcome in four of them. The pooled odds ratio (OR) of COPD from VGDF was 1.69 [95% confidence interval (CI) 1.34;2.13], greater in Kazakhstan [OR 1.96 (95% CI 1.35;2.85, N = 2 studies)] compared to Russia [OR 1.52 (95% CI 1.13;2.05, N = 2 studies)]. The pooled PAF% was 6% (95% CI 2; 14%) from three studies.Conclusions: Population-based studies in the CIS get little attention with very few studies published. Although the effect was greater in Kazakhstan compared to Russia, the overall effect did not differ from studies published in the rest of the world. Research capacity to study occupational risks of COPD should be strengthened to produce more evidence of higher quality.

Occupational disease claims and non-occupational morbidity in a prospective cohort observation of nickel electrolysis workers

“…Respiratory diseases as the leads in the occupational burden in our nickel electrolysis workers 18 are consistent with the overall assumption that aerosol inhalation is the dominating occupational exposure in this industry 19 . Exposure to vapors, gases, dusts and fumes has been demonstrated to explain a significant fraction of respiratory disease in a population since long time ago 20 ; however, it is only recently that studies from the Russian Federation emerged in the English literature 21 . Population attributable fraction % (PAF%) found is this meta-analysis and equaled 6%, was indeed an underestimate of the burden of occupational respiratory disease because of the likely exposure classification bias, when exposure may be underestimated or reported inaccurately.…”

Evaluation of Work-Related Symptoms by Job Exposure Matrix in Chronic Pulmonary Diseases - A Cross-sectional Study

“…Multiple studies have shown the significance of occupational exposures in asthma and COPD. [9][10][11] JEM showed that nearly half of our participants were exposed to occupational hazards with different prevalence of HMW, LMW and mixed exposure. HMW such as latex, aerosol and plants, LMW such as wood, metals, detergents, isocyanate and mixed exposure such as metal working, fluids, textiles, and agriculture have been shown to induce both asthma and COPD.…”

“…По данным последнего, наиболее крупного систематического обзора ущерба от указанных профессиональных воздействий в возникновении респираторной патологии, популяционный атрибутивный риск развития хоБЛ от них может достигать 14%, хронического бронхита -13% [12]. В странах бывшего Советского Союза, по данным мировой литературы, этот вопрос изучен недостаточно, лишь немногочисленные исследования уделяли вопросу роли профессиональных факторов в развитии этого заболевания должное внимание, а диагноз был подтверждён соответствующим образом [13].…”
