2000-2010: Biennial. 2011-present: Annual. The Centers for Disease Control and Prevention, Office on Smoking and Health (OSH) and the Food and Drug Administration, Center for Tobacco Products (CTP) began collaborating together on the NYTS starting on the 2011 cycle year. This collaboration has made it possible to field NYTS on an annual basis since 2011, as well as, helping to fulfill tasks assigned to both federal agencies while preventing data replication. The NYTS questionnaire has a core set of questions, ranging from 45 to 50, which will be asked annually and agreed upon by both agencies. On odd numbered years, the NYTS questionnaire will more closely align to tasks assigned to OSH and on even numbered years the NYTS questionnaire will more closely align to tasks assigned to CTP.
Mode of Collection:
Survey conducted in middle and high schools.
Use of cigarettes, cigars, smokeless tobacco, and other tobacco products within the past 30 days.
U.S. students in grades 6 through 12.
NYTS uses a three-stage cluster sampling design to generate a cross-sectional, nationally-representative sample of students in grades 6-12 from all 50 states and the District of Columbia. Data are adjusted for nonresponse and weighted to produce national prevalence estimates, while accounting for the complex survey design.
Response Rates and Sample Size:
In 2009, of 222 randomly sampled schools, 205 participated; of 24,266 students randomly selected at participating schools, 22,679 participated, yielding an overall response rate of 84.8 percent.
Since these data were collected from youths attending middle and high school, they may not be representative of all youths in the U.S. Youths who have dropped out of school are more likely to smoke than youths who are in school.
