Background: Dangers of babies' exposure to secondhand smoke (SHS) are well-documented. Less is known about how to effectively communicate these dangers, although a cumulative number of messages may influence behavior change. This study assessed postpartum smokers' reported frequency (dosage) of SHS messages and associations of messages with smoking and child exposure.

Methods: This study is part of an ongoing intervention, Philadelphia FRESH (Family Rules for Establishing Smoke-free Homes), for underserved postpartum smokers. Frequencies of SHS messages from formal (e.g., physician), personal (family), and media sources were reported by mother and a significant other. Separate multivariate analyses explored influence of message type on outcomes (cigarettes smoked/day, intention to quit, and child exposure.) Controlling variables with bivariate associations were included in multivariate models.

Results: The 356 mothers reported an average of smoking 12 cigarettes and exposing babies to 7 cigarettes per day; 28% reported intention to quit. Receiving a higher dose of SHS messages from personal sources (B=.121, p=.02) and media (B=.117, p=.05) reported by moms related to fewer cigarettes smoked per day in their respective models. Receiving a higher dose of media messages reported by moms related to intention to quit (OR=1.47, p=.04). No type of SHS messages received by moms related to baby SHS exposure; however, a higher total dose of SHS messages obtained by significant others reduced risk of baby exposure (B=.09, p=.04). Complete cotinine data will be available for presentation.

Conclusion: We will discuss implications of results and potential influence of social influences in reducing baby SHS exposure.

Learning Objectives:
To examine the potential influence of secondhand smoke information offered by health professionals, media, and friends/family on maternal smoking and child exposure.
