Place matters in perceived tobacco exposure among Korean American young adults: mixed methods approach.

A sequential mixed methods study was conducted to identify factors influencing perceived norms about smoking and to examine the association of acculturative contexts and normative beliefs among Korean American young adults (KAYA) who face increased risk of smoking. Content analysis of data from 67 participants in 10 focus groups in 2010 led to the development of an online survey in 2012 (N = 475). KAYA overestimated smoking prevalence, reporting Korean-owned businesses (KOB) as primary places of exposure. Our findings revealed that visits to KOB predicted perceived norms about smoking. Modifying perceptions about social norms and involuntary tobacco exposure may be critical in reducing smoking among KAYA. The study's limitations are noted.
