Passive Tobacco Exposure and Sudden Infant Death Syndrome
Keyword(s):
To the Editor.— Drs Schoendorf and Kiely1 report increased risk of SIDS, both in mothers smoking during and after pregnancy ("combined exposure") and in mothers smoking only afterward ("passive exposure"). Most previous studies2-18 that reported that maternal smoking is associated with SIDS considered only smoking during pregnancy, but some2,4,11,15 considered smoking after pregnancy. However, I am unaware of any previous study which attempted separation of smoking during and after pregnancy. Although such an attempt is commendable, certain problems with the analysis and data of Drs Schoendorf and Kiely merit comment.
