Statistical development for the analysis of longitudinal survey data from the International Tobacco Control project
There is an urgent need for developing and applying methods for analyzing longitudinal survey data. The proposed research aims to address that need with data from the International Tobacco Control (ITC) Project, which is conducting parallel longitudinal surveys across 20 countries to evaluate the impact of tobacco control policies (e.g., warning labels, smoke-free laws). These methods will also examine the natural smoking and cessation history of individuals and whether that history varies across countries. ITC is supported by the Ontario Institute for Cancer Research (OICR); Dr. Geoffrey Fong (supervisor) was the first researcher to become an OICR Senior Investigator. Substantial implications of this project arise for disease prevention and public expenditure in Ontario, which is conducting its own longitudinal survey of smoking. As such, methods developed for ITC will be useful for research organizations in Ontario, including Cancer Care Ontario, the OICR, and the Centre for Addiction and Mental Health.
