Mexico - San Luis Potosi (Age 13-15): GYTS Highlights

Summary

The Global Youth Tobacco Survey (GYTS) in Mexico-San Luis Potosi, conducted among 13-15-year-olds (n=~1391) in 2008, provides a representative sample using a two-stage cluster design with high school/student response rates (~89%).

Key Findings

1. Tobacco Use Prevalence:

   • Current use of any tobacco product: 23.7% (M:24.4%, F:22.9%)
   • Cigarette smoking (past 30 days): 20.2% (M:21.2%, F:19.3%)
   • Use of other tobacco products: 9.3% (M:11.0%, F:7.8%)
   • Ever used cigarettes: 52.7% (M:56.5%, F:49.2%)

2. Key Risk Factors & Determinants Assessed:

   • Exposure to Secondhand Smoke (SHS): High exposure reported, including presence at home (36.7%), other homes (around half), and homes of parents who smoke (43.2%). Over one-third of students live in homes with others smoking.
   • Availability/Access & Price: Most students buy cigarettes easily from stores (51.6%), and almost half don't face age-based refusal (51.2%).
   • Media Exposure: Students consistently saw pro-tobacco messages (billboards: 75.8%, print ads: 63.9%) and anti-smoking messages (85.1%). Significant proportion had cigarette logo objects (18.4%).
   • Attitudes: Strong majority believe SHS is harmful (88.2%) and support banning smoking in public places (82.6%+, 95.5% among current smokers). Perceived benefits of smoking (more friends, looks) via media were reported by adolescents, though less linked to girls in surveys. Nearly 90% of youth desire to quit smoking (58.8% current smokers).
   • School/Policy: Smoking restricts effectiveness varies, but most schools (~70%) covered content on tobacco harms/cessation effects, only about half discussed smoking reasons related to youth peer group.
   • Cessation Use: High desire to quit and reported past cessation attempts (63.1%) often associated with seeking help.
   • Company Contact: A small number (9.8%) were offered free cigarettes in the previous year.

Conclusion

Substantial tobacco use exists among this age group, influenced by SHS exposure, easy access to tobacco, pro-tobacco media, and normative social beliefs, contrasting with youth's own negative attitudes towards SHS. High prevalence of desire to quit among youth and current smokers highlights need for interventions.
