INTRODUCTION Few studies have examined the transitions of smokers in the general population through multiple periods of daily, occasional smoking, or abstinence over time. Transitions from daily to occasional smoking are particularly of interest as these may be steps toward cessation. METHODS The Ontario Tobacco Survey panel study followed 4,355 baseline(More)
Truly global standards and definitions will likely never exist for tobacco control surveillance. One difference across definitions of smoking status is whether or not a lifetime consumption of 100 cigarettes is a necessary criterion for ever and current smoking. Frequently asked questions about this measure demonstrate a need for information on its(More)
The availability of low-cost cigarettes undermines tobacco control’s most effective measure to reduce smoking prevalence: keeping cigarette prices high by raising tobacco taxes.1 The discount cigarette market share has grown considerably since 2003,2 with discount cigarettes selling for $10-$15 less per carton than premium brands. Contraband cigarettes –(More)
INTRODUCTION Discrete classification of smokers by intention to quit is desirable in many public health and clinical settings. METHODS Two methodological studies examine measurement properties of measures of discrete-time intention to quit smoking used in population-based tobacco surveillance surveys: an ecological comparison of rates of positive(More)
We examined young adult smoking cessation behaviors, coding cessation behavior as no attempt, quit attempt (< 30 days), or abstinence (≥ 30 days) during follow-up from July 2005 through December 2008, observed in 592 young adult smokers from the Ontario Tobacco Survey. One in 4 young adults made an attempt; 14% obtained 30-day abstinence. Cessation(More)
OBJECTIVES Smoke-free policies not only reduce harm to non-smokers, they may also reduce harm to smokers by decreasing the number of cigarettes smoked and increasing the likelihood of a successful quit attempt. However, little is known about the impact of exposure to smoking on patios on smoking behaviour. DESIGN AND PARTICIPANTS Smokers from the Ontario(More)
Population-based samples of smokers are necessary for tobacco behavior monitoring and surveillance and for evaluating tobacco control programs and policies. We evaluated the sensitivity and specificity of a simple, one-question screener as a tool to maximize efficiency of obtaining a population representative sample of current smokers. This analysis was(More)
OBJECTIVES The number of quit attempts it takes a smoker to quit successfully is a commonly reported figure among smoking cessation programmes, but previous estimates have been based on lifetime recall in cross-sectional samples of successful quitters only. The purpose of this study is to improve the estimate of number of quit attempts prior to quitting(More)
INTRODUCTION Access to Nicotine Replacement Therapy (NRT) is a key public health intervention to reduce smoking. We assessed prevalence and correlates of use of NRT in Ontario, where NRT is available without prescription. METHODS Participants were a representative sample of 2262 adult smokers in the Ontario Tobacco Survey cohort. Prospectively measured(More)
INTRODUCTION The mediating role of cessation medications in the association between health professional advice and quitting behaviors is unclear. METHODS Data were from the Ontario Tobacco Survey longitudinal study, collected between July 2005 and June 2011 in Ontario, Canada. The analytic sample included 3437 baseline smokers who were seen by health(More)
