Introduction. In 2007 and 2012, the Global School-Based Student Health Survey (GSHS) and the Global Youth Tobacco Survey (GYTS) were implemented to estimate the prevalence of risk behaviors and protection factors among 13 to 15 year-old adolescents. Objective. To assess changes in dietary, body weight, tobacco and physical activity indicators in the past five years. Population and Methos. Cross-sectional study. A randomized, two-stage sampling with 600 schools selected at a national level was used. Students from randomly selected courses were invited to answer a self-administered questionnaire (either the GSHS or the GYTS). Results. In 2012, the GSHS was completed by 20 697 students from 544 schools, while the GYTS was completed by 2062 students from 73 schools. Between 2007 and 2012, overweight and obesity prevalence significantly increased (overweight: 24.5% in 2007, 28.6% in 2012; obesity 4.4% in 2007, 5.9% in 2012), while the consumption of sugar-sweetened beverages and fast food remained high. A slight improvement was observed in the level of physical activity (12.7% in 2007, 16.7% in 2012), although it remains below what is recommended. The prevalence of tobacco use was reduced (24.5% in 2007, 19.6% in 2012), but access to tobacco products and exposure to secondhand smoke remains high in public places, including schools. Conclusions. The spread of the overweight and obesity epidemic calls for a need to consolidate actions tending towards a healthy diet and physical activity. Despite a decrease in the prevalence of tobacco use, it is necessary to continue strengthening tobacco control actions. © 2014, Sociedad Argentina de Pediatria. All rights reserved. Source
