Importance of urban air pollution in chronic respiratory problems.
The prevalence of nonspecific respiratory diseases was confirmed by two physical examinations taken five years apart. Data were analysed in relation to the area of residence within the city. Particular emphasis was placed on higher or lower levels of atmospheric air pollution. Using multivariate methods of analysis it was shown that air pollution increased the risk of: persistent cough or phlegm, chronic bronchitis and reduced ventilatory capacity in the group of man exposed to occupational hazards. Additionally, it was noted that amongst men reporting persistent cough or phlegm, the prevalence of exacerbation of these symptoms was much greater in residents of more highly polluted parts of the city. In women, the prevalence of exacerbation of symptoms was associated with particular indoor environments.
