Chronic bronchitis and associated factors in workers at a South African welding company

摘要

Abstract

Chronic bronchitis affects individuals in both developed and developing countries resulting in a poor quality of life. Emphysema and chronic bronchitis constitute chronic obstructive pulmonary disease (COPD) which is among the diseases that result in a high mortality rate. This study was conducted to find out about the prevalence of chronic bronchitis and the associated factors in workers of a South African welding company. A retrospective cross-sectional design was used whereby a self-administered questionnaire was used to gather the information from the participants who gave an informed consent. Thirty-eight participants (43.2%) reported suffering from chronic bronchitis. More welders (62.2%) had chronic bronchitis than office workers (30%) and fitters (28.6%). Chronic bronchitis was significantly associated with asthma as well as respiratory symptoms such as shortness of breath, chest pain, chest, and irritation to the nasal cavity (p<0.05). Chronic bronchitis was highly prevalent among workers in this welding company. Occupational health and safety measures that include avoiding exposure to pollutants and proper use of respiratory protective devices are essential to prevent chronic bronchitis.
