This toolkit was provided to researchers who attended the Tobacco Research Network on Disparities’ (TReND) pre-conference workshop, Research to Reduce Tobacco-Related Inequalities: Worldwide Implications For and Exemplars of Tobacco Control.  They explored how factors of social stratification (e.g. gender, socioeconomic class, race, ethnicity, and caste) play influential roles in tobacco-related outcomes that lead to inequalities in illness and mortality; and communication access, literacy, and use; and from effective health and policy interventions.
