Mexico-Villa Hermosa Global Youth Tobacco Survey Summary (GYTS)

The Global Youth Tobacco Survey (GYTS) conducted in Mexico-Villa Hermosa in 2008 among students aged 13-15 provides data on tobacco use prevalence and key determinants. A representative sample of 1,267 students from 1st, 2nd, and 3rd grades of Secondary and 1st grade of High School was surveyed using a two-stage cluster sampling method, with high response rates: school (100.0%), class (93.9%), student (82.9%), and overall (77.8%).

Key Findings Summary:

• Prevalence of Tobacco Use:

  • Ever smoked cigarettes: 40.5% (Boys: 44.4%, Girls: 36.8%)
  • Current users of any tobacco product: 20.3% (Boys: 22.9%, Girls: 17.9%)
  • Current cigarette smokers: 14.4% (Boys: 15.6%, Girls: 13.3%)
  • Current users of other tobacco products: 8.6% (Boys: 10.5%, Girls: 6.8%)

  • 23.4% of never smokers are likely to initiate smoking next year.
  • Exposure to secondhand smoke (SHS) is moderate: 27.3% live in homes where others smoke, and 45.6% are exposed outside home. Overall, 89.4% support banning smoking in public places, with 78.0% believing SHS is harmful.

  • Brand awareness: 12.8% have objects with cigarette logos.
  • School-based interventions: 73.5% learned about smoking dangers in class, 65.8% were taught effects of tobacco use.

This survey highlights high rates of tobacco use among youth and underscores the need for comprehensive school-based and community tobacco control programs to reduce initiation, exposure, and use.
