Overview:
The Global Youth Tobacco Survey (GYTS) conducted in Goiania, Brazil, in 2002 examined tobacco use prevalence and its determinants among students aged 13-15. It highlights key factors such as access, exposure to secondhand smoke (SHS), attitudes, and media influence, with findings relevant for tobacco control programs.

Survey Methodology:

• Employed a two-stage cluster sampling design with probability proportional to enrollment size.
• High response rates: School response rate 88.0%, class rate 100.0%, student rate 82.1%, overall response rate 72.3%.
• Target population: 7th and 8th grade elementary and 1st grade high school students (N=770 participants).

Highlights:

• Nearly half (40%) of students ever smoked cigarettes, with high current use (15.2%) of any tobacco product.
• SHS exposure is widespread, affecting over one-third of students both at home and in other settings.
• Strong support for smoking bans in public spaces (86.2% agree).
• Media plays a significant role, with balanced exposure to anti-smoking and pro-tobacco messages.
• Prevention efforts, such as education and cessation help, are valued, but youth still face barriers like affordable access and normalization.
