Mexico - Leon GYTS Summary

Overview

The Mexico - Leon Global Youth Tobacco Survey (GYTS), conducted in 2005, is a school-based survey targeting students aged 13-15 in grades 1, 2, and 3. It used a two-stage cluster sampling design with a response rate of 88.6%, involving 1,530 students from selected schools and classes. The survey assesses tobacco use prevalence and determinants, including access/availability, price, exposure to secondhand smoke (SHS), cessation, media, and school curriculum.

• Current use of any tobacco product: 26.1% (boys 31.4%, girls 20.7%).
• Current cigarette smoking: 24.2% (boys 30.4%, girls 18.3%).
• Current use of other tobacco products: 7.1% (boys 7.4%, girls 6.8%).
• Among never smokers, 26.5% are likely to initiate smoking in the next year.

Knowledge, Attitudes, and Determinants
