Article Synopsis
- Spirometry is a test used to evaluate lung function by comparing it to normal levels in healthy non-smokers, focusing on metrics like forced vital capacity (FVC) and the FEV/FVC ratio.
- The study analyzed data from over 14,000 participants aged 40 and older across 41 sites, revealing regional differences in FVC tied to factors like age and height, categorized into four regions: Europe/richer countries, Near East, Africa, and Far East.
- Findings showed significant regional variations in FVC values between men and women, particularly in Europe compared to the Far East, but minimal differences in the FEV/FVC ratio across regions.
Background: Dyspnoea is a common symptom of respiratory disease. However, data on its prevalence in general populations and its association with lung function are limited and are mainly from high-income countries. The aims of this study were to estimate the prevalence of dyspnoea across several world regions, and to investigate the association of dyspnoea with lung function.

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 standardised protocol and definition.

The intervention, implemented following a baseline survey (n = 498), included health and safety training of workers and managers, promotion of cotton dust control measures, and the provision of facemasks. Follow-up surveys were conducted at 1, 6, and 12 months post-intervention.

Methods: We used longitudinal data from 3957 participants of the multinational Burden of Obstructive Lung Disease study.
