A study of respiratory function among the workers engaged in ginning processes.

Area of Science:

• Occupational Health
• Pulmonary Medicine
• Environmental Health

Background:

• Respiratory effects of cotton dust exposure, including altered pulmonary function and chest tightness, are known.
• Limited studies exist on the health effects of cotton dust exposure in the Indian ginning industry.

Purpose of the Study:

• To investigate occupational details, morbidity, and respiratory function in cotton dust-exposed ginning workers.
• To assess pulmonary function changes across a working shift.

Main Methods:

• A cross-sectional study was conducted in Indian ginning units.
• Data collected via questionnaires, clinical examinations, and pulmonary function tests (PEFR, FEV1).

Main Results:

• No significant cross-shift changes in PEFR or FEV1 were observed.
• Chronic effects on lung function were noted, with declining trends linked to job duration, age, and smoking.
• Other reported health issues included backache and joint pain.

Conclusions:

• Ginning workers showed chronic lung function decline, unlike textile workers who may exhibit cross-shift changes, possibly due to differing exposure types.
• Recommends periodic clinical and lung function testing, along with monitoring of workplace dust, bacteria, and endotoxins.
