Chile - Santiago GYTS Survey Summary

This report summarizes the Global Youth Tobacco Survey (GYTS) conducted in Santiago, Chile, in 2003. The survey focused on tobacco use among 13- to 15-year-old students and its determinants.

Survey Design and Participants

• A two-stage cluster sample design was used to generate representative data for Santiago.
• 1,539 students from 7th and 8th basic education levels and 1st medio participated.
• Effective response rate: 88.9%.

Key Findings on Tobacco Use

• Prevalence:
  • 67.5% had ever smoked cigarettes.
  • 35.5% currently used any tobacco product.
  • 33.9% currently smoked cigarettes.
  • 4.9% currently used other tobacco products.
• Projection: 43.9% of never smokers were likely to start smoking in the next year.

Environmental and Social Determinants

• Access and Sales: A high percentage (83.1%) of cigarette buyers were not refused due to age. 53.0% purchased cigarettes from stores. 13.9% smoked at home.
• Family Influence: 67.2% had at least one smoking parent.
• Social Exposure: 26.5% had most or all friends who smoked.
• SHS Exposure: 60.6% lived in homes with smoking others; 69.8% were exposed to secondhand smoke outside their homes. 71.1% believed smoking should be banned in public places.

Knowledge and Attitudes

• Tobacco Risks: Over three-quarters (78.9%) encountered anti-smoking media in the past 30 days, but nearly 85.8% saw pro-cigarette ads outdoors and 69.8% in print media.
• Aspirations: 50.4% of current smokers wanted to quit, and many had tried stopping or received cessation help.
• Attitude Trends: Higher percentages of both boys and girls believed smoking affected social acceptability.
• Educational Influence: 43.2% were taught about smoking dangers in school during the previous year.

Overall Implications

The findings suggest high tobacco use prevalence in 13-15-year-olds, influenced by parental behavior, social circles, and accessibility. Significant exposure to secondhand smoke and tobacco marketing also emerged as concerns.

This data supports recommendations for comprehensive tobacco control interventions, particularly policies addressing youth accessibility, SHS exposure, and educational curricula about tobacco. These insights can aid policymakers and educators in preventing youth tobacco uptake.
