Smoking and tobacco use

Participants were asked whether they (had) smoked any tobacco (section: lifestyle & environment). The raw data from 1A was used to calculate various derivate scores, including pack years. Additionally updated derivate scores are available which include more time points.
Note that variables assessing the smoking behavior of adult female participants during pregnancy are listed here.
Secondhand smoking was also assessed, both overall and during pregnancy.
Nicotine dependence was assessed using the FTND.
