It has been suggested that the apparent relationship between children's cigarette smoking and their respiratory symptoms could be explained by the effect of parents' smoking upon both child's smoking and symptoms. This was investigated in a study of 6000 Derbyshire schoolchildren. Children who smoked regularly were more likely than nonsmokers to report cough first thing in the morning, cough at other times during the day or at night, and breathlessness. Children whose parents smoked were also more likely to report these symptoms than were the children of nonsmokers. Both the child's and parents' smoking were independently related to the child's respiratory symptoms. Morning cough was less prevalent than cough at other times during the day or at night, but the relationship between the child's smoking and morning cough was much closer than its relationship to cough at other times. The relationship between parents' smoking and the child's symptoms was similar for each symptom.
有人提出,儿童吸烟与其呼吸道症状之间的明显关系可以用父母吸烟对孩子吸烟及症状的影响来解释。在一项对6000名德比郡学童的研究中对此进行了调查。经常吸烟的儿童比不吸烟的儿童更有可能报告早晨起床时咳嗽、白天其他时间或晚上咳嗽以及呼吸急促。父母吸烟的儿童比父母不吸烟的儿童也更有可能报告这些症状。孩子吸烟和父母吸烟都与孩子的呼吸道症状独立相关。早晨咳嗽比白天其他时间或晚上咳嗽的发生率低,但孩子吸烟与早晨咳嗽之间的关系比与其他时间咳嗽的关系更为密切。父母吸烟与孩子每种症状之间的关系相似。
