Quitting activity and tobacco brand switching: findings from the ITC-4 Country Survey

OBJECTIVE:Among Australian smokers, to examine associations between cigarette brand switching, quitting activity and possible causal directions by lagging the relationships in different directions. METHODS: Current smokers from nine waves (2002 to early 2012) of the ITC-4 Country Survey Australian dataset were surveyed. Measures were brand switching, both brand family and product type (roll-your-own versus factory-made cigarettes) reported in adjacent waves, interest in quitting, recent quit attempts, and one month sustained abstinence. RESULTS: Switching at one interval was unrelated to concurrent quit interest.

Recent quit attempts more strongly predicted switching at concurrent (OR 1.34, 95 CI=1.18-1.52, p
