Secondhand Smoke Exposure Among Nonsmoking Adolescents in West Africa.

Objectives: We estimated the prevalence and determinants of secondhand smoke (SHS) exposure among nonsmoking adolescents in 9 West African countries.

Methods: We conducted a pooled analysis with nationally representative 2006 to 2009 Global Youth Tobacco Survey data. We used descriptive statistics to determine the prevalence of SHS exposure and inferential statistics using a multivariable logistic regression model to determine factors associated with SHS exposure.

Exploring Support for 100% College Tobacco-Free Policies and Tobacco-Free Campuses Among College Tobacco Users.

Background: Tobacco-free campus policy is identified as an effective means to address tobacco use on college campuses; however, the prevalence of tobacco-free policies (TFPs) in the United States remains low. This study explores college tobacco users' support for a university's TFP and tobacco-free campuses (TFCs) in general.

Methods: A standardized and structured questionnaire was administered to 790 college tobacco users recruited in a university located in a tobacco-growing region of the United States, during April-May 2011, to collect information on support for TFPs and TFCs and sociodemographic-political characteristics.
