Youth tobacco access and possession policy interventions: effects on observed and perceived tobacco use.

This study evaluated the effects of tobacco Purchase, Use and Possession (PUP) laws on student perceptions of adolescent tobacco use within towns and schools. Twenty-four towns were randomly assigned into two conditions, the experimental condition (E PUP) involved efforts to increase both PUP law enforcement and reduce minors' access to commercial sources of tobacco, whereas the control condition (C) focused only on efforts to reduce minors' access to commercial sources of tobacco. A hierarchical linear modeling analytical approach was selected due to the multilevel data and nested design.

Effects of youth tobacco access and possession policy interventions on heavy adolescent smokers.

This study evaluated the effects of tobacco PUP (Purchase, Use and Possession) laws on tobacco use patterns among students in twenty-four towns, which were randomly assigned into an experimental and a control group. The experimental group involved both PUP law enforcement and reducing minors' access to commercial sources of tobacco, and the condition for the control group involved only efforts to reduce minors' access to commercial sources of tobacco. The present study found that adolescents in the control group had a significantly greater increase in the percentage of youth who smoked 20 or more cigarettes per day when compared to the experimental group.

Youth smoking status: perceptions versus measurements.

Objective: To determine whether youths who have smoked cigarettes in the past 30 days perceive themselves as smokers.

Methods: Sensitivity and specificity for 3 classifications were analyzed and compared to youths' perceptions of smoking status.

Results: The common criterion of having smoked cigarettes in the past 30 days reflected youths' perceptions of their smoking status with modest accuracy although adding a second criterion of having also smoked 100 or more cigarettes in a lifetime more accurately reflects youths' perceptions of their smoking status.
