In a cross-sectional study on 433 schoolchildren (aged 6⁻9 years) from 9 schools in Austria, we observed associations between housing factors like passive smoking and lung function as well as improved lung function in children who had been breast-fed. The latter findings urged the question of whether the protective effects of breast-feeding act on environmental stressors or if they act independently. Therefore, the effect of passive smoking on lung function was stratified by breast-feeding. The detrimental effects of passive smoking were significant but restricted to the group of 53 children without breast-feeding. Breast-feeding counteracts the effect of environmental stressors on the growing respiratory organs.
在奥地利 9 所学校的 433 名 6-9 岁学童的横断面研究中，我们观察到住房因素（如被动吸烟）与肺功能之间存在关联，以及母乳喂养的儿童肺功能得到改善。这些发现促使人们提出这样一个问题：母乳喂养的保护作用是针对环境应激源，还是独立发挥作用。因此，我们按是否母乳喂养对被动吸烟对肺功能的影响进行了分层。被动吸烟的有害影响是显著的，但仅限于 53 名未母乳喂养的儿童。母乳喂养可以抵抗环境应激源对生长中呼吸器官的影响。
