“…Whether the dust exposure concentration exceeds the standard, the duration of exposure must be determined to assess the effect of occupational dust exposure on the deterioration in lung function. Many studies showed that workers with high exposure to respirable dust had a high incidence of abnormal lung function [ 23 , 24 ]. In the present study, excessive dust exposure concentrations were closely related to abnormal lung function, especially FEV 1 /FVC.…”

Objective: This study aims to determine the occupational health status of workers exposed to dust and the risk factors of lung function decline, to provide a basis for formulating corresponding occupational disease-prevention strategies. Methods: Data on 2045 workers exposed to dust, including their age, gender, exposure time, chest X-ray test results, and pulmonary function test results, were obtained from a key occupational disease monitoring project in Chongqing, China, in 2021. Chi-square tests and multifactorial logistic regression, and other methods, were used for statistical analysis. Results: The prevalence of pneumoconiosis-like changes was 0.83% (17/2045), and the prevalence of abnormal forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and FEV1/FVC was 4.25% (87/2045), 12.81% (262/2045), and 1.47% (30/2045), respectively. With increasing worker’s age, the prevalence of abnormal pneumoconiosis-like changes (p = 0.0065), FEV1 (p = 0.0002), FVC (p < 0.0001), and FEV1/FVC (p = 0.0055) all increased. Factors such as age, exposure duration, enterprise size, and dust exposure concentration were associated with abnormal lung function. Conclusions: Workers exposed to occupational dust have a high rate of abnormal lung function. The government, enterprises, and individuals should pay attention to occupational dust exposure, and various effective measures should be actively taken to protect the life and health of workers.

Pneumoconiosis as an occupational disease is a serious threat to the health of workers. Patients with pneumoconiosis are mainly engaged in dust-related work such as gold, coal, or iron mining, electric welding, or road work, and present with miliary nodules, fuse mass-like opacities, and cavity lesions on chest imaging. Clinical manifestations of pneumoconiosis include progressive chest tightness, dyspnoea, chest pain, coughing, expectoration, fever, and hypodynamia. Pneumoconiosis patients are prone to respiratory tract infections (including bacterial pneumonia and tuberculosis) because of poor disease resistance and will eventually lose the ability to work and fully function in daily life completely. Patients can lose their life because of complications such as pulmonary heart disease and respiratory failure. Disease prevention is the main method to control pneumoconiosis. We retrospectively analysed 516 cases of pneumoconiosis patients receiving whole lung lavage (WLL) procedure from May 2009–January 2015. The symptoms, pulmonary function, chest computed tomography manifestations, and living status were reviewed carefully. The improvement rate of chest tightness, chest pain, and dyspnoea was 99%, 90%, and 98%, respectively, 7 days after WLL procedure. The symptoms had improved in 235 patients at 3–6 months postoperatively. The therapeutic effect remained stable in 56 cases after 4–5 years. Chest tightness, chest pain, and dyspnoea were improved significantly, and pulmonary diffusion function and small airway resistance also improved. There was no progress in 62 patients 4–5 years postoperatively, as indicated by the chest computed tomography examination. Overall, WLL treatment is an effective method for treating pneumoconiosis.

Introducción. La minería se ha relacionado con problemas de salud de predominio respiratorio, causados por la exposición al carbón y a los diversos componentes que permanecen suspendidos en el aire de las minas, los cuales son un riesgo para contraer enfermedades de predominio respiratorio que clásicamente se manifiestan por tos, expectoración, hemoptisis y dolor en el pecho, entre otros síntomas. Objetivo. Determinar la prevalencia de la sintomatología respiratoria en los trabajadores mineros del municipio de Socotá (Boyacá) en diciembre de 2017.Metodología. Se llevó a cabo un estudio de tipo observacional, descriptivo y de corte transversal. Se incluyeron 794 trabajadores para tamizar síntomas indicativos de algún trastorno respiratorio importante.Resultados. Hubo predominio del grupo de edad de 36 a 45 años, con 240 (30,23 %) individuos. El grupo más sintomático fue el grupo B, con 48 a 69 meses de trabajo. La prevalencia de personas con sintomatología respiratoria fue de 5 % (n=40). El síntoma más prevalente fue la fatiga (n=134; 16,88 %). Al hacer una regresión logística multivariada dividida por una estratificación en meses de trabajo y hacer la comparación de toda la población contra el grupo B (48 a 96 meses), los síntomas de pérdida de peso, sudoración y dolor en pecho muestran una relación estadísticamente significativa. Conclusiones. La prevalencia de los sintomáticos respiratorios fue baja (n=40; 5 %) en esta población. Sin embargo, la regresión dio el indicio de que a mayor tiempo de exposición laboral, aumenta la aparición de síntomas en los trabajadores.
