The Kenya GYTS includes data on prevalence of cigarette and other tobacco use as well as information on five determinants of tobacco use: access/availability and price, environmental tobacco smoke exposure (ETS), cessation, media and advertising, and school curriculum. These determinants are components Kenya could include in a comprehensive tobacco control program. The Kenya GYTS was a school-based survey of students in standard 7, standard 8, form 1 and form 2 conducted in 2007.
A two-stage cluster sample design was used to produce representative data for Kenya. At the first stage, schools were selected with probability proportional to enrollment size. At the second stage, classes were randomly selected and all students in selected classes were eligible to participate. The school response rate was 100.0%, the student response rate was 89.4%, and the overall response rate was 89.4%. A total of 11,069 students participated in the Kenya GYTS.
