Common risk factors in the development of chronic bronchitis include cigarette smoking, air pollution, genetic factors, increasing age, male gender, allergy, and repeated airway infections.

Risk Factors

The most potent risk factor for development of chronic bronchitis is smoking. Other risk factors include: environmental exposures, genetic susceptibility, air pollution and respiratory infections.

Cigarette smoking

Occupational exposure

  • Dusts, gases, fumes, or organic antigens can contribute to increased airways responsiveness.[3][2][4]

Genetic factors

  • Alpha-1 antitrypsin (AAT) deficiency is the leading genetic risk factor for developing chronic bronchitis.[3][2][5] Some novel risk factors such as, small nucleotide polymorphisms and gene clusters, are assumed to be involved in developing chronic airway diseases.[6]

Developmentally abnormal lungs

  • Frequent childhood infection may cause scarring of lungs, decrease elasticity, thereby increasing risk for COPD.
