摘要：Objectives. To examine patterns of smokeless tobacco (SLT) use, by type, in wave 1 (2013–2014) of the Population Assessment of Tobacco and Health Study in the United States. Methods. We analyzed data from 32 320 adults (aged ≥ 18 years) to assess the use of pouched snus and other SLT products (loose snus, moist snuff, dip, spit, and chewing tobacco). Results. Overall, SLT use was most common among men, younger adults, non-Hispanic Whites, and nonurban respondents. Pouched snus users were more likely to report nondaily and polytobacco use than users of other SLT products. Respondents who used SLT some days were more likely to be current established cigarette smokers than those who used SLT every day (57.9% vs 20.2%). Furthermore, current established smokers who used SLT some days were more likely to smoke every day and had a higher median number of cigarettes smoked per day than smokers who used SLT every day. Conclusions. Polytobacco use, especially cigarette smoking, is common among SLT users. Pouched snus users are more likely to report nondaily snus use and polytobacco use than users of other SLT products. Although cigarette smoking continues to decline in the United States, the prevalence of smokeless tobacco (SLT) use has remained relatively unchanged over the past decade. 1,2 The 2012–2013 National Adult Tobacco Survey estimated that 2.6% of adults aged 18 years or older were current (everyday or some-day) users of SLT, 3 and SLT use was more common among young adults, men, non-Hispanic Whites, and nonmetropolitan area residents. 1,3 New SLT products have recently been introduced into the United States and have grown in market share. In particular, snus, a Swedish-style moist snuff tobacco, almost doubled its share in the SLT market in the United States between 2009 and 2010 alone. 4 Despite the rapidly changing SLT market, national data on newer SLT product use and detailed information on user behavior are limited. 5 The Population Assessment of Tobacco and Health (PATH) Study was established in 2011 to generate longitudinal epidemiological data on tobacco use behavior and health among the US population. 6 The PATH Study includes a detailed assessment of tobacco products with pictures to prompt recall, and was designed to assess snus use separately from use of other SLT products. Because virtually all snus sold in the United States is in pouched form, 4 the PATH wave 1 instrument (fielded between 2013 and 2014) collected information on pouched snus. In PATH wave 1 data, 0.8% of US adults reported pouched snus use and 3.1% reported other SLT use currently some days or every day. 7 To further understand population-level use across SLT product types, we analyzed PATH wave 1 adult data to explore the use of different SLT product types, including SLT user characteristics, other concurrent product use by SLT users, and self-reported reasons for SLT use. We focused on adults because of the relatively low prevalence of SLT use in youths (1.6% reported past-30-day use, including pouched snus) in the PATH Study. 7
