An analysis of data from 5903 children from a study of primary schools in England and Scotland in 1982 showed that the number of cigarettes smoked by the parents at home was significantly associated with the attained height of their children. This relation was statistically significant after allowing for parents' height, child's birthweight, mother's smoking during pregnancy, overcrowding and number of older siblings. Number of cigarettes smoked at home was more strongly related to height than number of cigarettes smoked by the mother during pregnancy. The results suggest that passive smoking may have an effect on the height of a child independent of genetic factors, the social environment and mother's smoking in pregnancy. Whether this is a direct effect of parents' smoking on the child's growth remains unclear.
对1982年英格兰和苏格兰小学一项研究中5903名儿童的数据进行分析后发现，父母在家中吸烟的数量与孩子的最终身高显著相关。在考虑了父母身高、孩子出生体重、母亲孕期吸烟情况、居住拥挤程度以及哥哥姐姐数量后，这种关系在统计学上具有显著性。在家中吸烟的数量比母亲孕期吸烟的数量与身高的关系更为密切。结果表明，被动吸烟可能会对孩子的身高产生影响，且这种影响独立于遗传因素、社会环境和母亲孕期吸烟。父母吸烟对孩子生长是否有直接影响尚不清楚。
