Description
For female persons ages 18 to 49 who gave live birth in the past five years, who quit smoking for 7 or more days two or more times during their last pregnancy and started smoking again during pregnancy, QTLENGTH2PSTP reports the time units of the length of time that the person quit smoking during her most recent quit attempt during pregnancy.
Users should combine QTLENGTH2PSTP with QTLENGTH2PSNO, which reports the numeric values for the time units in QTLENGTH2PSTP, in order to identify the length of time that the person quit smoking during her most recent quit attempt during pregnancy.
