英格兰和苏格兰的的全国性健康与生长调查(NSHG)的资料表明,儿童身高与家庭中吸烟的人数有关。既往关于父母在家庭中吸烟与儿童身高的分析中,没有吸烟支数的资料。对于儿童生长与家庭中吸烟人数有明显关系的可能解释是父母均吸烟的家庭,母亲在孕期的吸烟量远远超过只有一方吸烟者。为了进一步对此进行研究,作者对所调查儿童的父母现在吸烟和母亲孕期的吸烟情况进行了调研分析。 Information from the National Health and Growth Survey (NSHG) in England and Scotland shows that the height of children is related to the number of people smoking in the home. In the past, parents did not have information on the number of smokers in their analyzes of smoking and child height in their families. A possible explanation for the apparent relationship between child growth and the number of smokers in the household is that both parents smoke and their mothers smoke far more during pregnancy than only one smoker. To further investigate this, the authors conducted a survey of current smoking among mothers and fathers of mothers and their mothers during pregnancy.
