Risk Factors and Etiological Issues of Chronic Simple (Nonobstructive) Bronchitis

Abstract

Clinical and epidemiological examination of the population confirmed the risk factors of chronic non-obstructive bronchitis such as active and passive smoking, air pollution, occupational dust, infections: frequent respiratory infections such as bronchitis, pneumonia, genetic predisposition, age, gender can contribute to the development of chronic bronchitis. The role of persistent and chronic viral infection in the formation of chronic non-obstructive bronchitis has been confirmed. The interaction of risk factors (how various risk factors interact with each other to increase the risk of developing chronic bronchitis) has not been fully studied.
