Brazil - Boa Vista GYTS Summary (Ages 13-15)

Core Content

The Global Youth Tobacco Survey (GYTS) conducted in Boa Vista, Brazil in 2004 provides a comprehensive overview of tobacco use and related factors among students aged 13-15. The survey, based on a two-stage cluster sampling method, collected data from 1,072 students across 7th and 8th grades of elementary school and 1st grade of high school, with a high overall response rate of 87.6%.

The survey assessed prevalence of tobacco use, knowledge and attitudes, access and availability, exposure to secondhand smoke (SHS), cessation behaviors, media and advertising influence, and school-based education. These components are essential for designing a comprehensive tobacco control program in the region.

Conclusion

The GYTS data from Boa Vista highlights significant tobacco use among youth, with 17.9% currently using any tobacco product. SHS exposure is widespread, and students are largely aware of the harms of smoking, as evidenced by high levels of support for smoking bans and anti-smoking messages. However, media influence and peer behavior remain important factors in shaping youth attitudes toward tobacco. The school curriculum also plays a role in educating students about the dangers of tobacco, but there is room for improvement in both the reach and impact of these educational efforts.
