Prevalence and burden of asthma among US working adults by industry and occupation-United States, 2020-2021

Assess the prevalence of current asthma, asthma attacks/episodes, and asthma-related emergency room (ER) visits by industry and occupation and estimate the proportion of current asthma cases associated with employment during 2020-2021.

The 2020-2021 National Health Interview Survey data for persons aged ≥18 years who were employed at any time during the 12 months prior to the interview were analyzed.

An estimated 12.7 million US working adults had current asthma. Of those, 40% had an asthma attack/episode and 8.6% had an asthma-related ER visit. Prevalence varied by sociodemographic characteristics, industry, and occupation. Highest asthma prevalence was among workers in the administrative, support, waste management, and remediation industry and the community and social services occupation. Nearly half of workers with current asthma in the arts, entertainment, and recreation industry and arts, design, entertainment, sports, and media occupations reported having an asthma attack/episode. Workers in the accommodations and food services industry and food preparation and serving related occupation had the highest asthma-related ER visits. The proportion of current asthma cases attributable to employment was estimated to be 9.2% by industry and 12.2% by occupation.

An estimated 1.2-1.5 million asthma cases among workers might be attributable to employment by industry and occupation. Disparities in asthma prevalence, asthma attacks/episodes and asthma-related ER visits among workers exist. These findings underscore the importance of early identification of asthma cases in relation to work and implementation of targeted interventions (including, training and education, personal protective equipment use, health surveillance, workplace policies), especially among workers employed in industries and occupations with elevated asthma prevalence.
