Decline in lung function among cement production workers: a meta-analysis
Reviews on Environmental Health
|October 11, 2017
Summary
Exposure to cement dust significantly impairs lung function, reducing key indicators like forced vital capacity (FVC) and forced expiratory volume in the first second (FEV1). This meta-analysis confirms cement dust
Area of Science:
- Occupational Health
- Environmental Medicine
- Pulmonary Medicine
Background:
- Conflicting results exist regarding the health effects of cement dust exposure.
- Previous studies on cement dust and lung function have yielded varied outcomes.
- A comprehensive analysis is needed to reliably estimate the impact of cement dust exposure.
Purpose of the Study:
- To conduct a meta-analysis on the pathogenic outcomes of cement dust exposure.
- To provide a reliable estimate of the effects of cement dust on lung function indicators.
- To synthesize existing research on occupational exposure to cement dust.
Main Methods:
- Systematic literature search of PubMed and other databases.
- Inclusion of studies identified through expert interviews and research center inquiries.
- Estimation of point and pooled effect sizes with 95% confidence intervals.
Main Results:
- Analysis included 5371 exposed and 2650 unexposed individuals.
- Significant reductions observed in forced vital capacity (FVC) by -0.48 L.
- Decreases noted in forced expiratory volume in the first second (FEV1) by -0.7 L, FEV1/FVC% by -0.43 L, PEFR by -0.73 L/min, and FEF25-75 by -0.36 L/s.
Conclusions:
- Cement dust exposure has a significant detrimental impact on pulmonary function.
- Key lung function indicators including FVC, FEV1, FEV1/FVC, PEFR, and FEF25-75 are reduced.
- The findings underscore the occupational health risks associated with cement dust.

Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:

01:20Chronic Obstructive Pulmonary Disease-I: Introduction
3.9K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
