Multi-country, cross-national comparison of youth tobacco use: Findings from Global School-based Health Surveys

Abstract

Objective Describe the prevalence of current cigarette smoking and other tobacco use among 13–15 year olds across 44 countries and 110 sites participating in the Global School-based Health Survey (GSHS), and compare these results with previous findings from the Global Youth Tobacco Survey. Methods The GSHS is conducted in countries using standardized sampling and survey methodology procedures. Smoking and other tobacco use prevalence was compiled from fact sheets available on the GSHS web site from the available 110 sites where the survey has been conducted and resulting data processed. Tobacco use prevalence rates are weighted to adjust for the probabilities of nonresponse and varying probabilities of selection. Boy to girl ratios were calculated to examine gender differences in tobacco use prevalence. Results Current smoking rates ranged widely from a low of approximately 1 in 100 students in Tajikistan and India to a high of more than 1 in 4 students in certain sites in Chile and Colombia, and more than 1 in 5 in other sites in Chile, Ecuador, Argentina, and Colombia. Other tobacco use prevalence ranged from a low of 1.0% in Hangzhou, China to a high of 43.7% in Northwest Namibia. Conclusion This is the first multi-country, cross-national study of tobacco use involving GSHS data. Results provide an opportunity to examine youth tobacco use in several countries and compare results with the Global Youth Tobacco Survey (GYTS) which is a more extensive global surveillance of youth tobacco use.
