Youth Studies 2000-2009
Health studies among 15-16-year-olds in 2000-2004
The youth studies began with 15-16-year-olds from Oslo- and Hedmark in 2000-2001. Adolescents from four other counties - Oppland, Nordland, Troms og Finnmark - participated in 2002, 2003 og 2004.
The adolescents were asked to complete a questionnaire about different topics such as health, disease, diet, sport, local environment and how they felt. The main questionnaire was identical for each county, plus some additional questions that varied between counties.
Blood samples and other biological material were not included in the studies. Height and weight data are self-reported.
The adolescents decided whether or not to participate. They had been given an information brochure in advance and completed a consent form before completing the questionnaire. Their parents were informed. In most venues, a public health nurse was responsible for carrying out the study.
The youth study in Oslo 2000-2001 was also called UNGHUBRO because it was carried out with a health study among adults; HUBRO. 7343 adolescents in 10th grade (15-16 years-old) participated which was 88 per cent of the potential group.
Hedmark and Oppland
The studies took place in spring 2001 in Hedmark and autumn 2002 in Oppland. The response was 88 per cent in Hedmark and 90 per cent in Oppland.
Nordland, Troms and Finnmark
The Nordland study took place in spring 2004. In Nordland, the youth study was a collaboration between the Norwegian Institute of Public Health and the University of Tromsø.
The response was 88 per cent which gave a good picture of adolescent health and lifestyle in 2004 in Nordland.
In Troms and Finnmark, the youth studies took place in spring 2003 in a collaboration between the Norwegian Institute of Public Health and the Centre for Sami Health Research at the University of Tromsø. The study took place in Tromsø in 2002.
The response was 81 per cent in Troms and 71 per cent in Finnmark, which is somewhat lower than the other counties. However, the participation is still considered to be relatively high and gives a good picture of adolescent health and lifestyle in Troms og Finnmark in 2002-2003.
Studies of 18-19 year-olds in Oslo and Hedmark in 2004
All the 15-16 year-olds who took part in the Oslo and Hedmark studies in 2000-2001 were contacted in spring 2004 and asked to complete another questionnaire called "Ungdom 2004" (Youths 2004). In addition there was a group of "new" 18-18 year-olds. In total, 4,700 adolescents took part, of which 4,000 participated twice. The purpose was to study the link between physical activity on adolescent mental health.
Like the 15-16 year-olds, the 18-19 year-olds were asked questions about health habits, physical and mental disorders and diseases.
The results are important to improve the health service for adolescents in the future.
All participants completed a questionnaire and consent form. The participants were asked to provide an oral mucosa sample.
Number of participants
Almost all the students registered in the school list in Oslo in 2004 took part. 90 per cent of those invited at school took part. In the postal study, the response was lower at 43 per cent. 77 per cent of the Oslo adolescents who took part in 2001, participated in 2004. In Hedmark 55 per cent took part. In total, 4,000 took part in both 2001 and 2004.
Ungdom 2004 was a collaboration between the Norwegian Institute of Public Health and the University of Oslo.
