Describing Youth Quitting Behaviour
Is there evidence that youth smokers in New Zealand want to quit smoking?
Short Answer – YES!
• 75% of youth smokers would not smoke again if they had their lives over
• Almost half (50%) of youth smokers are thinking about quitting
• 35% of youth made at least one quit attempt in the last 12 months
Youth who have “Ever Quit”
• Current smokers (n=178) were asked
“Have you ever quit for more than a week?”
• Yes responses (n=113) defined as ever quit and compared against no responses (n=65)

Likelihood – Ever quit
Summary
• There are clear factors that influence the likelihood of youth being ever smokers
• There is minimal variation across indicators and their effect on the likelihood of having ever quit
• Indicates that the risk factors observed for youth being smokers are not barriers for making a quit attempt
Where To…
• Further analysis to come
• Look more in depth at attitudes to quitting and self-efficacy on having ever made a quit attempt
Youth smokers want to quit!
