Abstract
BACKGROUND: Comparative effectiveness studies of state tobacco quitlines and Web-based tobacco cessation interventions are limited. In 2009, the US Centers for Disease Control and Prevention undertook a study of the comparative effectiveness of state quitlines and Web-based tobacco cessation interventions. METHODS: Standardized questionnaires were administered to smokers who enrolled exclusively in either quitlines or Web-based tobacco cessation services in 4 states in 2011-2012. The primary outcome was the 30-day point prevalence abstinence (PPA) rate at 7 months both between and within interventions. RESULTS: A total of 4086 participants were included in the analysis. Quitline users were significantly older, more heterogeneous in terms of race and ethnicity, less educated, less likely to be employed, and more often single than Web-based users. The 7-month 30-day PPA rate was 32% for quitline users and 27% for Web-based users. Multivariate models comparing 30-day PPA rates between interventions indicated that significantly increased odds of quitting were associated with being partnered, not living with another smoker, low baseline cigarette use, and more interactions with the intervention. After adjustments for demographic and tobacco use characteristics, quitline users had 1.26 the odds of being abstinent in comparison with Web-based users (95% confidence interval, 1.00-1.58; P = .053). CONCLUSIONS: This is one of the largest comparative effectiveness studies of state tobacco cessation interventions to date. These findings will help public health agencies develop and tailor evidence-based tobacco cessation programs. Further research should focus on users of Web-based cessation interventions sponsored by state health departments and their cost-effectiveness.
