Chile - Santiago Global Youth Tobacco Survey (GYTS) Summary

Core Content

The Chile - Santiago Global Youth Tobacco Survey (GYTS) is a school-based survey conducted in 2008 that collected data on the prevalence of cigarette and other tobacco use among students in primary grades 7th and 8th, and secondary grades 1st and 2nd. The survey included 3,590 students aged 13-15 and used a two-stage cluster sampling design to ensure representative data. The overall response rate was 79.9%, with a high school response rate of 92.0% and a 100.0% class response rate.

The survey examined five key determinants of tobacco use: access/availability and price, exposure to secondhand smoke (SHS), cessation, media and advertising, and school curriculum. These factors are critical in shaping youth tobacco behavior and can be used to develop a comprehensive tobacco control program.
