Indicators for Non-Communicable Diseases (NCD)

Tobacco use among adolescents (Indicator 9)

The indicator describes the following: The proportion of adolescents using tobacco.

This indicator is part of Target (5): 30 per cent reduction in tobacco use.

The indicator covers current daily or non-daily use of tobacco. Tobacco use mainly consists of smoking and the use of snus. We present data on the proportion of adolescents who smoke and the proportion who use snus or smoke. 

Results

From 1975 until 2016, smoking (daily or non-daily) fell from just under 50 per cent to under 20 per cent among men, and from around 40 per cent to 10 per cent among women, in the 16-19 age group. For both genders, there was a period from 1990 to 2000 during which the decline halted. 

The decline in smoking coincides with a rise in the use of snus among both genders. The increase in the regular use of snus has declined over the most recent periods and, among young men, use declined between 2010 and 2015. Despite the rise in the use of snus, there has been a net decline in the total proportion of individuals who responded that they smoked or used snus.

Description 

The Norwegian Survey of Smoking Habits is a telephone-based, nationwide survey of tobacco use (questions about smoking and snus) among individuals aged 16-79, and undertaken by Statistics Norway on behalf of the Norwegian Institute of Public Health. The survey has been conducted annually since 1973 and the response rate has been around 60 per cent in recent years, around 70 per cent in the 1990s and around 90 per cent in the 1970s. From and including 1985, questions about snus have also been asked. 

From 1973 until 1991 the survey was conducted as a supplementary part of the Labour Force Survey. During this period, around 2500 people participated annually. From 1992 until 2016, the survey formed part of Statistics Norway’s Omnibus Survey and Travel Survey. During this period, 2000 people were invited to participate each quarter, with the exception of the second and last quarter of 2015 and 2016 when 3000 people were invited. The survey was not conducted from the first and third quarter of 1992, the first to the third quarter of 1994, in the third quarter of 1998 and the second quarter of 2000.

Numerator

  • The proportion of adolescents in the 16-19 age range who responded that they smoke and/or use snus on a daily or non-daily basis, stated as a percentage.

Years are stated in five-year groups  (1973-1977… 2013-2016)

The data shown are representative of the age distribution in the Norwegian Survey of Smoking Habits. 

Interpretation and sources of error

Combining daily use and non-daily use entails different consequences for different groups. For young men, non-daily smoking and non-daily snus use have remained relatively stable over time. For women, non-daily smoking is declining over time, while non-daily use of snus is increasing. The result is that there is less of a decline in smoking among women and the use of snus is increasing more over time when we look at regular use compared with daily use.

Data quality

The quality of the data are deemed to be good, although the response rate has declined over time. In recent years, Statistics Norway has calculated weightings to adjust for deviations from the sample. The use of weightings in the generation of tables has very little effect on the results. However, the sample size will be too small to provide useful responses to questions requiring the sample to be broken down into smaller parts, for example one-year age groups or counties.
