Ventilatory Functions, Oxygen Saturation, and Quality of Life Response to Long Time Cement Dust Exposure

Completed
Conditions
Occupational Diseases
Registration Number
NCT05047497
Lead Sponsor
Cairo University
Brief Summary

Thousands of people are working daily in a dusty environment. Many studied reported respiratory symptoms and ventilatory disorders among Factory workers who exposed to cement dust. But the evidence for respiratory effect and daily activities over a long time of cement dust exposure has not been conclusive

Detailed Description

A total of 49 subjects working in a cement production factory were assessed and divided into three groups according to the total period of work exposure. Groupe A (18 subjects) with work period \< 10 years, group B (13 subjects) with work period 10-15 years, group C (18 subjects) with work period \> 15 years. The ventilatory functions, oxygen saturation, and quality of life were assessed in the three groups. RESULTS: The study results revealed a statistically significant difference between the three groups in the mean values of FVC (%), FEV1/FVC (%), SPO2.
