Parenthood and smoking
Parents’ smoking is harmful to infants’ health. While it is well established that the fraction of mothers smoking during pregnancy is non-negligible, it is an open question of how many parents actually quit smoking to account for the adverse health effects accruing to their offspring. It is also unknown for how long smoking is reduced after first childbirth. This paper investigates these questions in a longitudinal analysis. The analyzed time period covers smoking patterns several years before childbirth and up to twenty years afterwards. Women’s smoking probability already drops several years before first childbirth and it remains reduced until the first child turns 18 years old. In the second and third trimester of pregnancy, the drop is largest by around 75 percent.
