The goal of this project is to evaluate the effectiveness (Phase II) of a text-based program
to be called Quit4Baby to support smoking cessation efforts of pregnant women who smoke.
In Phase II, Dr. Abroms will conduct a randomized clinical trial among 500 pregnant smokers
who have been recruited from users of text4baby - the first large scale mobile health
application in the United States. Developed and operated by Voxiva and Healthy Mothers,
Healthy Babies (HMHB)—collaborators in this program -text4baby is a free national service
that has enrolled more than 800,000 pregnant women and mothers of infants 0-1 nationwide and
delivered more than 150 million health messages to them including messages encouraging them
not to smoke during pregnancy and referring them to quit lines.
Hypothesis 1: Pregnant smokers who receive quit4Baby + text4Baby will demonstrate higher
levels of knowledge about the dangers of second hand smoke and the benefits of smoking
cessation for mothers and their infants than text4baby only users.
Hypothesis 2: Pregnant smokers who receive quit4baby + text4baby will report significantly
higher rates of calling a quit line, discussions with their health provider and/or use of
cessation counseling than those who receive Text4baby alone.
Hypothesis 3: Pregnant smokers who receive quit4baby + text4baby will have significantly
more favorable quitting outcomes compared with text4baby alone.

are recruited from text4baby users, we are confident that they will have cell phones
and text messaging capacity.
