OBJECTIVE: To estimate the effectiveness of a tailored multicomponent community-based smoking cessation intervention among Chinese immigrants living in New York City, implemented within the context of state and city-wide tobacco control policy initiatives for the general population.
METHODS: A pre-post-test quasi-experimental design with representative samples from Chinese populations living in two communities in New York City: Flushing, Queens, the intervention community and Sunset Park, Brooklyn, the comparison community. From November 2002 to August 2003 baseline interviews were conducted with 2537 adults aged 18-74. In early 2006, 1384 participants from the original cohort completed the follow-up interview. During the intervention period (October 2003 to September 2005), both communities were exposed to tobacco control public policy changes. However, only Flushing received additional linguistically and culturally-specific community-level tobacco control interventions.
RESULTS: From 2002 to 2006 overall smoking prevalence among Chinese immigrants declined from 17.7% to 13.6%, a relative 23% decrease. After controlling for socio-demographic characteristics, there was an absolute 3.3% decrease in smoking prevalence attributed to policy changes with an additional absolute decline in prevalence of 2.8% in the intervention community relative to the control community.
CONCLUSION: City-wide tobacco control policies are effective among high-risk urban communities, such as Chinese immigrants. In addition, community-based tailored tobacco control interventions may increase the reduction in smoking prevalence rates beyond that achieved from public policies.
