Analysis of Pneumoconiosis Cases and Characteristics from 2004-2019 in Shandong Province

Abstract

Pneumoconiosis is the most common occupational disease in the world; it is deadly but preventable. We aimed to evaluate the epidemiological trends and characteristics of pneumoconiosis in the large industrial Shandong Province of China to facilitate prevention and control measures. Data from 2004-2019 were extracted from an occupational disease reporting system regarding morbidity, regional distribution, industry distribution, types of pneumoconiosis, dust exposure duration, and age at diagnosis. A total of 15,853 pneumoconiosis cases were identified and classified as stage I (13,879 cases), stage II (1,402 cases), and stage III (572 cases). Yantai was the region with the most cases, which mainly involved cases of silicosis and coal workers’ pneumoconiosis among individuals who were employed in mining and manufacturing industries. A high risk of pneumoconiosis was associated with rock drilling, road heading, and coal mixing. The average age at diagnosis was 52 years, and the average duration of dust exposure was 18 years. The incidence of pneumoconiosis in Shandong Province is still high, with clear concentrations in specific regions, industries, and types of work, which should be targeted for pneumoconiosis prevention and control measures. Industrial regulations and steps to control dust generation are needed to help reduce the incidence of pneumoconiosis.
