| Abstract: | The data obtained by the authors indicate that the relationship between chronic nonspecific pulmonary diseases (CNPD) was only found in men and was established to be particularly dependent on the age, onset and duration of tobacco smoking. In men, the relationship manifested itself in the fact that with age and increase of the period of tobacco smoking the risk for pulmonary diseases rose. In women, such relationship appeared immaterial, but they also demonstrated a tendency towards the growth of the CNPD incidence with the rise of the period of tobacco smoking. |
