title: [Frequency of chronic bronchitis in an intensely polluted urban zone. Preliminary results in children. Analysis of the implicated factors].
abstract: The starting point is that environment factors induce chronic bronchitis in adults and children and that the disease in adult is a consequence of respiratory tree susceptibility which might be better evidenced during childhood. The authors have studied a group of children aged 0--14 years in a highly air-poluted workers' quarter in the city of Baia-Mare. The frequence of chronic bronchitis was 10.3% with higher values in children below 5 years and over 10 years, the age group 5--9 years being a group with higher resistance to this disease. The figures are three times higher in boys than in girls, on possible endogenous factors. The girls could be, however, more subjected to "passive smoking" because of smokers presence in family and in bed room. The number of children in a family did not correlate with chronic bronchitis frequence. This frequence was significantly influenced by allergic and ear-nose-throat phenomena in the history, more evidently in 0--4 years and 10-14 years groups of age. These elements could be thus considered as risk factors. They also indicate the place to be acted upon in order to prevent chronic bronchitis in children.
