Smoking and alcohol consumption at age 15


Regular smoking or excessive drinking in adolescence has immediate and long-term health consequences. Children who establish smoking habits in early adolescence increase their risk of cardiovascular diseases, respiratory illnesses and cancer. They are also more likely to experiment with alcohol and other drugs. Alcohol misuse is itself associated with a range of social, physical and mental health problems, including depressive and anxiety disorders, obesity and accidental injury (Currie et al., 2008).

Results from the Health Behaviour in School-aged Children (HBSC) surveys, a series of collaborative cross-national studies conducted in most OECD countries, allow for monitoring of smoking and drinking behaviours among adolescents. Generally, today girls smoke more than boys, but more boys get drunk. Between 13 and 15 years of age, the prevalence of smoking and drunkenness doubles in many OECD countries.

Children in Austria, Finland, Hungary, the Czech Republic and Italy smoke more often, with weekly rates of 20% or more for both boys and girls (Figure 2.1.1). In contrast, 10% or less of 15-year-olds in the United States, Canada and Sweden smoke weekly. Most countries report higher rates of smoking for girls, although only Spain and Austria have differences in excess of 5%. Greece, Finland, Hungary, -Iceland, Poland and the Slovak Republic are the only countries where smoking is more prevalent among boys.

Drunkenness at least twice in their lifetime is reported by 40% or more of 15-year-olds in Denmark, the United Kingdom and Finland (Figure 2.1.2). Across all surveyed countries, 29% of girls and 33% of boys have been drunk on two or more occasions, with much lower rates in the United States, and Mediterranean countries such as Greece, Italy and Portugal. Boys are more likely to report repeated drunkenness. Switzerland, Belgium, Hungary and the Slovak Republic have the biggest differences, with rates of alcohol abuse being 5‐10% higher than those of girls. In Poland, differences are even greater, with repeated drunkenness among boys being over 10% higher than girls. Norway, Spain, Canada and the United Kingdom are the only countries where more girls report repeated drunkenness, and in each case rates are less than 5% higher. . . . . .
