Tobacco use transitions in the United States: The National Longitudinal Study of Adolescent Health.

ABSTRACT:

Objectives

The purpose of this study is to evaluate and describe transitions in cigarette and smokeless tobacco (ST) use, including dual use, prospectively from adolescence into young adulthood.

Methods

The current study utilizes four waves of the National Longitudinal Study of Adolescent Health (Add Health) to examine patterns of cigarette and ST use (within 30 days of survey) over time among a cohort in the United States beginning in 7th-12th grade (1995) into young adulthood (2008-2009). Transition probabilities were estimated using Markov modeling.

Results

Among the cohort (N=20,774), 48.7% reported using cigarettes, 12.8% reported using ST, and 7.2% reported dual use (cigarettes and ST in the same wave) in at least one wave. In general, the risk for transitioning
