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

NCT05047497 | Completed

• 1 other identifier: Cairo
• Study Type: observational
• Target: 49
• Locations: 1 country
• Sites: 1

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

Conditions

Occupational Diseases

Outcome Measures

Primary Outcomes (3)

• The ventilatory functions

  ventilatory function tests were used to assess FVC (%), FEV1/FVC (%),PEF (%), FEV1 (%)

  8 months

• oxygen saturation

  measuring oxygen saturation using SPo2

  8 months

• quality of life were assessed

  the mean values of the physical functioning item and energy/fatigue item in the quality of life questionnaire

  8 months

Study Arms (3)

less than 10 years working

workers who work in cement factories in a period of time less than 10 years

Diagnostic Test: questionaire and ventilatory function test

from 10-15 years working

workers who work in cement factories in a period of time from 10-15 years

Diagnostic Test: questionaire and ventilatory function test

more than 15 years working

workers who work in cement factories in a period of time more than 15 years

Diagnostic Test: questionaire and ventilatory function test

Interventions

questionaire and ventilatory function test DIAGNOSTIC_TEST

we assessed the arterial blood gases and the ventilatory functions and quality of life of whole three groups

from 10-15 years working; less than 10 years working; more than 15 years working

Eligibility Criteria

• Age: 25 Years - 50 Years
• Sex: male
• Age Groups: Adult (18-64)
• Sampling Method: Probability Sample

Study Population

Out of sixty persons who were assigned to this study, a total of 49 subjects (group 1 n = 18, group 2 n = 13 and group 3 n = 18) completed the study (Fig. 1). In all groups, A, B and, C; height and weight scale were obtained for calculating BMI. The distribution of smokers between different age groups was measured (table ) The pulmonary function tests were performed to evaluate the capacity and volume of the lungs among the participants. Spirometry measurements, including FVC, FEV1, ratio of FEV1 to FVC (FEV1/FVC), forced expiratory flow 25-75% (FEF 25-75%), and peak expiratory flow (PEF
