Summary of Brazil-Curitiba Global Youth Tobacco Survey (GYTS)

The Brazil-Curitiba GYTS is a school-based survey conducted in 2002, targeting students aged 13-15 in grades 7th-8th elementary and 1st high school. It employed a two-stage cluster sampling design with a high overall response rate of 76.2%, involving 1,161 students from selected schools, classes, and students.

Prevalence rates reveal significant tobacco use: about 43.5% of students had ever smoked cigarettes, and 15.0% were current users of any tobacco product. This is broken down as 12.6% smoking cigarettes, 3.4% using other tobacco products, with higher rates among girls and lower among boys. Self-reported initiation beliefs are high, with 19.3% of never smokers likely to start smoking.

Key determinants of tobacco use include high exposure to secondhand smoke (SHS), with 40.4% of students living in homes where others smoked and 60.3% exposed outside the home. Cessation attempts are notable, as 62.8% of current smokers want to quit, and over half have tried to stop or received help. Media exposure shows high awareness of anti-smoking messages (92.1% seen in the past 30 days), but also strong pro-tobacco influence, such as 84.4% seeing billboard ads and frequent free cigarette offers.

Student attitudes are mixed: 76% believe SHS is harmful, 84-80% support smoking bans in public places, and many hold misconceptions about smoking's attractiveness or believe smoking helps with stress. Exposure to social factors (e.g., parental or friend smoking) is common, with 38% having at least one smoking parent.

The school component indicates that most students (57%) were taught about smoking dangers, but students rarely discussed age-specific reasons for smoking or received comprehensive tobacco effects education.

This survey highlights the need for comprehensive youth tobacco control programs addressing access, SHS, media, and education.
