Summary of Namibia Global Youth Tobacco Survey (GYTS)

Introduction

The Namibia Global Youth Tobacco Survey (GYTS) was conducted among students aged 13-15 in grades 7-9 in 2004. It assessed the prevalence of tobacco use, access to tobacco products, exposure to secondhand smoke, and attitudes toward tobacco control, using a school-based survey methodology.

Methodology

The survey employed a two-stage cluster sampling design. At the first stage, schools were selected with probability proportional to enrollment size. In the second stage, classes were randomly chosen, and all students in selected classes participated. Response rates were high: 94% for schools, 98.1% for classes, and 85.1% for students, with an overall response rate of 78.5%. A total of 3,646 students took part.

Key Findings

• Tobacco Use: 38.3% of students had ever smoked cigarettes; 25.8% currently used any tobacco product; 18.8% smoked cigarettes; 15% used other tobacco products.
• Secondhand Smoke Exposure: 40.3% lived with others smoking in their home; 58.5% were exposed to smoke outside the home; 28.1% had parents who smoked.
• Attitudes and Knowledge: A majority (40.3%) thought smoking should be banned in public places; 73.4% of current smokers wanted to quit; 69.5% reported seeing anti-smoking media messages.
• Media Influence: High exposure to pro-cigarette advertisements (e.g., on billboards and in media); some students saw anti-smoking ads or had tobacco company interactions.
• School Factors: 31.2% were taught about smoking dangers in school; students discussed smoking reasons in class.

This survey highlights significant youth tobacco use and associated determinants in Namibia, providing data for targeted tobacco control programs.
