Workers' Occupational Dust Exposure and Pulmonary Function Assessment: Cross-Sectional Study in China

Area of Science:

• Occupational Health
• Pulmonary Medicine
• Environmental Health

Background:

• Workers exposed to occupational dust face significant health risks.
• Understanding the impact of dust exposure on lung function is crucial for prevention.

Purpose of the Study:

• To determine the occupational health status of dust-exposed workers.
• To identify risk factors associated with lung function decline in these workers.
• To inform occupational disease prevention strategies.

Main Methods:

• Analysis of data from 2045 dust-exposed workers in Chongqing, China.
• Utilized chest X-ray and pulmonary function test results.
• Employed statistical methods including Chi-square tests and logistic regression.

Main Results:

• Prevalence of pneumoconiosis-like changes was 0.83%.
• Abnormal lung function (FEV1, FVC, FEV1/FVC) ranged from 1.47% to 12.81%.
• Age, exposure duration, enterprise size, and dust concentration correlated with adverse lung function outcomes.

Conclusions:

• Occupational dust exposure leads to a high incidence of abnormal lung function.
• Age and prolonged exposure are significant risk factors for lung function decline.
• Proactive measures are essential for protecting worker health from occupational dust.
