Two hundred and fourteen children aged 7-11 years had tests of lung function performed. Mothers were asked about their past and current smoking habits and whether their children had ever had pneumonia or severe bronchitis. The findings suggest a relationship between early childhood bronchitis or pneumonia and impairment of lung function in later childhood and also suggest that maternal smoking habit may contribute directly to impairment of lung function in children.
对214名7至11岁的儿童进行了肺功能测试。研究人员询问了这些儿童母亲过去和当前的吸烟习惯，以及她们的孩子是否患过肺炎或严重支气管炎。研究结果表明，儿童早期支气管炎或肺炎与儿童后期肺功能受损之间存在关联，同时也表明母亲的吸烟习惯可能直接导致儿童肺功能受损。
