Patterns and determinants of tobacco use among adolescents aged 13-15 years in 75 low and middle-income countries Público

Abstract

Tobacco smoking is the leading cause of death worldwide. Approximately 80% of the world's one billion smokers reside in low and middle income countries. Tobacco use is mostly initiated during adolescence. There is a dearth of surveillance data on tobacco use among adolescents in developing countries. Using data from the global youth tobacco survey (GYTS), which was obtained between 2007 and 2014, the author examined the patterns and determinants of tobacco use among adolescents in low and middle income countries (LMIC). This study included a total of 163,852 adolescents, aged 13-15years, from low and middle income countries in the 6 World Health Organization (WHO) regions, including the African region, the Americas region, the South-East Asia region, the European region, the Eastern Mediterranean region and the Western Pacific region. Multivariate logistic regression was used to analyze the use of the following tobacco products: current cigarette smoking, current smokeless tobacco, any tobacco use, and poly-tobacco use. The prevalence of adolescent cigarette smoking was 9.1%, smokeless tobacco - 5.3%, any tobacco use - 16.2%, and poly-tobacco use - 3.8%. The odds of cigarette smoking in LMIC was significantly lower in the African region (adjusted odds ratio [aOR] = 0.71; 95% confidence interval [CI]: 0.54-0.93) and region of Americas (aOR = 0.48; 95% CI: 0.36-0.63) compared to that of the European region, after adjusting for gender, cigarette brand, country income categorization, survey year, and tobacco excise tax. Examination of findings indicated an increase in the prevalence of cigarette smoking in the African, Eastern Mediterranean, South-East Asia and Western Pacific regions. This highlights the need to improve and strengthen national and regional tobacco regulatory policies.
