Why the study?

This study was conducted to characterize the pneumoconiosis disease burden through DALYs, incidence, prevalence, and mortality rates from 1991 to 2023 across the United States.

Population

Individuals of all sexes and ages across all US states

Design

Database-based epidemiological trend analysis

Key result

From 1991 to 2023 in the United States, pneumoconiosis mortality fell by 51.08%, DALYs dropped by 47.12%, and incidence decreased by 23.62%, while prevalence increased by 69.34%.

Overview

Supports sustained workplace dust controls; leaves open drivers of slower incidence declines.

Key Points

  • This research aims to characterize the disease burden of pneumoconiosis in the U.S. from 1991 to 2023 using DALYs, incidence, prevalence, and mortality rates.
  • Utilized Global Burden of Disease database for data from all U.S. states
  • Analyzed incidence, prevalence, DALYs, and death rates from 1991 to 2023
  • Computed percentage changes in metrics across the studied years.
  • Total pneumoconiosis mortality decreased by 51.08%.
  • DALYs dropped by 47.12% and annual incidence decreased by 23.62%.
  • Prevalence of pneumoconiosis nearly doubled, increasing by 69.34% across the study period.

O
Outcome
Disease burden through disability-adjusted life years (DALYs), incidence, prevalence and mortality rates

While pneumoconiosis mortality and incidence have declined in the US from 1991 to 2023, prevalence has nearly doubled, indicating improved survival and accumulation of chronic cases.
