Preface to ITC Brazil Wave 3 Technical Report

The International Tobacco Control Policy Evaluation Project (the ITC Project) is a multicountry prospective cohort study designed to measure the psychosocial and behavioural impact of key policies of FCTC in 29 countries. On November 03, 2005, Brazil ratified the World Health Organization Framework Convention on Tobacco Control (WHO FCTC). In 2008, the ITC Project at University of Waterloo began to partner with Cristina de Abreu Perez and colleagues from the Brazilian National Cancer Institute (INCA) to create the ITC Brazil Project, a longitudinal prospective longitudinal study of adult (18+) smokers and non-smokers The ITC Brazil Wave 1 Survey was conducted from April to June 2009 among 1,215 adult smokers and 610 adult non-smokers (Total=1,825). The second wave was conducted from October 2012 to February 2013 (i.e., three years after the first wave) among 1,222 adult smokers and 608 non-smokers (Total=1,830). The third wave was conducted from September 29, 2016 (i.e., more than three years after the second wave) and completed March 02, 2017 among 1,358 adult smokers (including 142 quitters) and 470 non-smokers (Total=1,828). This report documents the third wave of the International Tobacco Control Policy Evaluation (ITC) Brazil Survey.
