Geographical variation in lung function: results from the multicentric cross-se...
Burney, Peter G.; Potts, James; Knox-Brown, Ben; Erhabor, Gregory; Hacene Cherkaski, Hamid; Mortimer, Kevin; Anand, Mahesh Padukudru; Mannino, David M.Spirometry is used to determine what is "unusual" lung function compared with what is "usual" for healthy non-smokers. This study aimed to investigate regional variation in the forced vital capacity (FVC) and in the forced expiratory volume in one second to FVC ratio (FEV1/FVC) using cross-sectional data from all 41 sites of the multinational Burden of Obstructive Lung Disease study. Participants (5,368 men; 9,...
Prevalence of chronic cough, its risk factors and population attributable risk ...
Abozid, Hazim; Patel, Jaymini; Burney, Peter; Hartl, Sylvia; Breyer-Kohansal, Robab; Mortimer, Kevin; Nafees, Asaad A.; Al Ghobain, MohammedBackground: Chronic cough is a common respiratory symptom with an impact on daily activities and quality of life. Global prevalence data are scarce and derive mainly from European and Asian countries and studies with outcomes other than chronic cough. In this study, we aimed to estimate the prevalence of chronic cough across a large number of study sites as well as to identify its main risk factors using a stan...

Ratanachina, Jate; Amaral, Andre F.S.; De Matteis, Sara; Lawin, Herve; Mortimer, Kevin; Obaseki, Daniel O.; Harrabi, Imed; Denguezli, MeriamBackground: Chronic obstructive pulmonary disease has been associated with exposure in the workplace. We aimed to assess the association of respiratory symptoms and lung function with occupation in the Burden of Obstructive Lung Disease study. Methods: We analysed cross-sectional data from 28 823 adults (≥40 years) in 34 countries. We considered 11 occupations and grouped them by likelihood of exposure to organ...
Small airways obstruction and its risk factors in the Burden of Obstructive Lun...
Knox-Brown, Ben; Patel, Jaymini; Potts, James; Ahmed, Rana; Aquart-Stewart, Althea; Cherkaski, Hamid Hacene; Denguezli, Meriam; Elbiaze, MohammedBackground: Small airway obstruction is a common feature of obstructive lung diseases. Research is scarce on small airway obstruction, its global prevalence, and risk factors. We aimed to estimate the prevalence of small airway obstruction, examine the associated risk factors, and compare the findings for two different spirometry parameters. Methods: The Burden of Obstructive Lung Disease study is a multination...

Chronic airflow obstruction and ambient particulate air pollution
Amaral, Andre F.; Burney, Peter G.; Patel, Jaymini; Minelli, Cosetta; Mejza, Filip; Mannino, David M.; Seemungal, Terence A.; Mahesh, Padukudru AnandSmoking is the most well-established cause of chronic airflow obstruction (CAO) but particulate air pollution and poverty have also been implicated. We regressed the sex-specific prevalence of CAO from 41 Burden of Obstructive Lung Disease study sites against smoking prevalence from the same study, the gross national income per capita, and the local annual mean level of ambient particulate matter (PM2.5) using ...

COPD: should diagnosis match physiology?
Studnicka, Michael; Horner, Andreas; Sator, Lea; Buist, A. Sonia; Lamprecht, Bernd; Zhong, NanShan; Liu, Shengming; Lu, Jiachun; Ran, Pixin; Wang, DaliWe are very grateful to Dr. Vanfleteren and colleagues for commenting on our data regarding overdiagnosed COPD2 and for putting this evidence into the framework of the current understanding of the disease. Based on the data presented on overdiagnosis, and on prior Burden of Obstructive Lung Disease (BOLD) observations on underdiagnosis,3 we truly believe that our worldwide community of pulmonary specialists cou...
