Glass bangle workers exposed to toxicants show high rates of chronic bronchitis and lung function impairment. Occupational exposures significantly increase the risk of airway obstruction and ventilatory dysfunction.

Area of Science:

  • Occupational Medicine
  • Pulmonary Medicine
  • Environmental Health

Background:

  • Glass bangle manufacturing involves exposure to various pulmonary toxicants.
  • Chronic bronchitis and ventilatory dysfunction are significant health concerns in this industry.

Purpose of the Study:

  • To evaluate pulmonary function in glass bangle workers with chronic bronchitis.
  • To compare lung function and disease prevalence with asymptomatic workers and unexposed controls.
  • To identify risk factors associated with ventilatory dysfunction in this population.

Main Methods:

  • Pulmonary function tests were conducted on 73 chronic bronchitic glass bangle workers.
  • Data was compared with 220 asymptomatic workers and 88 controls.
  • Relative risk and prevalence of ventilatory dysfunction were calculated.

Main Results:

  • Prevalence of ventilatory dysfunction was 45.2% in chronic bronchitic cases, 19% in asymptomatic workers, and 2.3% in controls.
  • Relative risk of airway obstruction was significantly higher in both asymptomatic (8.3x) and chronic bronchitic (19.6x) workers compared to controls.
  • Age over 30 was associated with bronchial obstruction in chronic bronchitic cases; smoking status was not significant.

Conclusions:

  • Occupational and environmental factors in glass bangle work contribute to high rates of chronic bronchitis and lung dysfunction.
  • Prolonged exposure (over 10 years) increases the risk of airway obstruction.
  • Interventions are needed to mitigate occupational hazards and protect worker respiratory health.
