"However, limited information exists on trends in smokeless tobacco use among U.S. youths," writes Israel T. Agaku, D.M.D., M.P.H., of the Harvard School of Public Health, Boston, and colleagues.
As reported in a Research Letter in the May 15 issue of JAMA
, the authors analyzed recent trends in prevalence of smokeless tobacco use among youths using the 2000-2011 National Youth Tobacco Survey, a biennial national cross-sectional survey of U.S. middle school and high school students. Samples during 2000 through 2011 ranged from 35,828 students in 324 schools in 2000 to 18,866 students in 178 schools in 2011. Current smokeless tobacco use was defined as use of snuff, chewing, or dipping tobacco for 1 or more days within the past 30 days.
The researchers found that no significant change in overall smokeless tobacco prevalence occurred between 2000 (5.3 percent) and 2011 (5.2 percent). Downward trends were observed in the age groups of 9 to 11 and 12 to 14 years. Prevalence increased in the age group of 15 to 17 years.
"The prevalence of smokeless tobacco use among U.S. youths did not change between 2000 and 2011 and remained generally low. However, subgroup differences were observed. The use of modified traditional smokeless tobacco products, such as moist snuff, coupled with lower taxes on smokeless tobacco products (vs. cigarettes) may have contributed to the stable prevalence of smokeless tobacco (vs. the declining trend for cigarettes)," they write. "these findings emphasize the need for evidence-based interventions to reduce smokeless tobacco use among youths."
