Use of serial measurements of peak flow in the diagnosis of occupational asthma.

Occup Med

Department of Respiratory Medicine, East Birmingham Hospital, United Kingdom.

Published: July 1993

Occupational asthma is best verified by physiological measures, including (1) measurement of lung function on a single occasion with bronchodilator response, (2) measurement of lung function before and after a workshift, and (3) repeated measurement of PEF over long periods of time, including readings at and away from work. The author describes a qualitative method for distinguishing patterns of PEF change at and away from work which has been effective in the diagnosis of work-related asthma.

Objective: Asthma poses a significant health burden in South Asia, with increasing incidence and mortality despite a global decline in age-standardized prevalence rates. This study aims to analyze asthma trends from 1990 to 2021, focusing on prevalence, incidence, mortality, and disability-adjusted life years (DALYs) across South Asia. The study also assesses the impact of risk factors like high body mass index (BMI), smoking, and occupational exposures on asthma outcomes.
