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.
研究起点是环境因素会诱发成人和儿童的慢性支气管炎，且成人慢性支气管炎是呼吸道易感性的结果，这种易感性在儿童期可能表现得更为明显。作者对巴亚马雷市一个空气污染严重的工人聚居区的一组0至14岁儿童进行了研究。慢性支气管炎的发病率为10.3%，5岁以下和10岁以上儿童发病率更高，5至9岁年龄组对该病的抵抗力较强。考虑到可能的内源性因素，男孩的发病率是女孩的三倍。然而，由于家庭和卧室中有吸烟者，女孩可能更容易受到“被动吸烟”的影响。家庭中孩子的数量与慢性支气管炎的发病率无关。有过敏史和耳鼻喉疾病史会显著影响发病率，在0至4岁和10至14岁年龄组中更为明显。因此，这些因素可被视为危险因素。它们还指明了预防儿童慢性支气管炎应采取行动的方向。
