Influence of social environment in smoking among adolescents in Turkey

Abstract

Background: The aim of this study was to examine the social determinants of smoking among adolescents attending school and/or work. Methods: A survey was carried out on 6012 adolescents aged between 13 and 17 years in 15 cities, recruited from schools, vocational training centres and work places. A self-completed questionnaire was used for data collection. Single- and multi-level regression analyses were run to estimate models. Results: Ever smoking and current smoking rates were 41.1% and 10.5% among girls, and 57.5% and 25.2% among boys. These rates were 47.0% and 13.3% among those who only attended school, 62.2% and 31.7% among those who attended school and worked simultaneously, and 67.5% and 43.0% among those who worked and did not attend school. In multi-level analysis, the major predictors of current smoking were close friends smoking [odds ratio (OR) 3.48; 95% confidence interval (CI) 1.93-6.27], no knowledge of harmful effects of short-term smoking (OR 2.15; 95% CI 1.74-2.67), vulnerability to peer pressure (OR 1.90; 95% CI 1.48-2.46), negative self-perception (OR 1.69; 95% CI 1.31-2.18) and male sex (OR 1.68; 95% CI 1.30-2.16). Mothers higher education was a predictor for girls' smoking, while mother's lower education was a predictor for boys' smoking. At the school level, smoking prevalence was a predictor of current smoking (OR 1.07; 95% CI 1.05-1.08). Conclusions: Smoking patterns were similar to Western countries in several aspects, while male prevalence rates were higher and the impact of gender-related predictors was significant. Our findings suggest that youth smoking prevention policies should address personal, familial and educational environmental level requirements, taking into consideration the gender differences in addition to international guidelines.
