INTRODUCTION: Tobacco quitlines are evidence-based cessation resources but have been underutilized. The purpose of this study is to provide population-level data about quitline awareness and utilization in the United States and to assess correlates of awareness and utilization. METHODS: Data were from the 2009-2010 National Adult Tobacco Survey. Descriptive statistics were produced for national- and state-level quitline awareness and for national quitline utilization. Bivariate and multivariable logistic regressions were used to identify correlates of quitline awareness and utilization. RESULTS: Quitline awareness among the total sample was 33.9% (current smokers 53.9%, former smokers 34.0%, never-smokers 27.0%). Awareness varied by state (range: 35.8%-84.6% for current smokers). Among current smokers who tried to quit in the past year, correlates of lower awareness included being Black, non-Hispanic, and making <$50,000 annually; correlates of higher awareness included having seen a health professional, higher state tobacco program expenditures, and being female. Among smokers who made at least one quit attempt in the previous year and were aware of the quitline, quitline utilization was 7.8%. Higher state tobacco program expenditure, health professional advice, and being Black, non-Hispanic were correlated with higher utilization; older age was correlated with lower utilization. Awareness was significantly associated with use at the state level (r = .98, p < .01). CONCLUSION: Although the majority of smokers in the United States are aware of quitlines, only a small percentage of those trying to quit utilize them. State tobacco program expenditures and receipt of advice from a health professional were associated with both higher quitline awareness and higher utilization.

Tobacco use continues to be the leading cause of preventable disease and death in the United States; cigarette smoking accounts for approximately 443,000 premature deaths annually. In 2009, the prevalence of smoking among U.S. adults was 20.6% (46 million smokers), with no significant change since 2005 (20.9%). In 2010, approximately 69% of smokers in the United States reported that they wanted to quit smoking. Approximately 44% reported that they tried to quit in the past year for ≥1 day; however, only 4%-7% were successful each year. Tobacco dependence has many features of a chronic disease: most patients do not achieve abstinence after their first attempt to quit, they have periods of relapse, and they often require repeated cessation interventions. At least 70% of smokers visit a physician each year, and other smokers visit other health-care professionals, providing key opportunities for intervention. The 2008 update to the U.S. Public Health Service (PHS) Clinical Practice Guideline: Treating Tobacco Use and Dependence recommends that clinicians and health-care delivery systems consistently identify and document tobacco use status and treat every tobacco user seen in a health-care setting using the 5 A's model: 1) ask about tobacco use, 2) advise tobacco users to quit, 3) assess willingness to make a quit attempt, 4) assist in quit attempt, and 5) arrange for follow-up. The PHS guideline also recommends the following as effective methods for increasing successful cessation attempts: individual, group, and telephone counseling; any of the seven first-line medications for tobacco dependence that are approved by the Food and Drug Administration (FDA); and provision of coverage for these treatments by health-care systems, insurers, and purchasers. However, clinicians and health-care systems often do not screen for and treat tobacco use consistently and effectively.
