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)
The purpose of this study was to explore individual- and school-level policy characteristics on student smoking behavior using an ecological perspective. Participants were 24,213 (51% female) Grade 10-11 students from 81 schools in five Canadian provinces. Data were collected using student self-report surveys, written policies collected from schools,(More)
BACKGROUND The use of network meta-analysis has increased dramatically in recent years. WinBUGS, a freely available Bayesian software package, has been the most widely used software package to conduct network meta-analyses. However, the learning curve for WinBUGS can be daunting, especially for new users. Furthermore, critical appraisal of network(More)
The purpose of this study was to determine whether there is a growing inequity in tobacco use, susceptibility to future smoking, and quit attempts among Off-Reserve Aboriginal (ORA) youth in Canada relative to Non-Aboriginal youth. Current smoking, susceptibility to future smoking and quit attempts were examined among a nationally representative sample of(More)
BACKGROUND Few researchers have the data required to adequately understand how the school environment impacts youth health behaviour development over time. METHODS/DESIGN COMPASS is a prospective cohort study designed to annually collect hierarchical longitudinal data from a sample of 90 secondary schools and the 50,000+ grade 9 to 12 students attending(More)
BBACKGROUND The 14 neighborhoods surrounding University of Chicago Hospitals (UCH) have both Chicago's highest "ambulatory-care-sensitive condition" hospitalization rates and lack of community-based care. To address these problems, in 2004, the Southside Medical Homes (SMH) Network began linking emergency department (ED) patients with 18 community(More)

BACKGROUND Smoking prevalence varies over time and place due to various social, environmental and policy influences. However, its spatio-temporal patterns at small-area level are poorly understood. This paper attempts to describe spatio-temporal patterns of adult (age > 18) and youth (age 12-18) smoking prevalence at the municipality level in Ontario,(More)
