title: [On the epidemiology of recurrent and chronic bronchopulmonary diseases-an examination of about 18000 children. 4. Investigation in the cities of Halle and Halle-Neustadt (author's transl)].
abstract: In Halle, an old city, and Halle-Neustadt, a town built in the past 10 years, our investigation was performed on 4418 children. We ascertained chronic or recurrent nonspecific bronchopulmonary diseases in 3,1% of them. 2,4% suffered from recurrent bronchitis, 0,4% from chronic bronchitis and 0,3% from bronchial asthma. Significant differences in the morbidity between the sexes were found only in asthma: boys were fallen ill twice often than girls. The frequency of morbidity lowered with increasing age significantly. Between Halle and Halle-Neustadt significant differences existed: in the old parts of Halle (especially in the centre, the eastern and southern districts) there were much more sick children than in the newly-built town.
