Overvåking av norsk kosthold - metoder og resultater
Kunnskap om endringer i matvarenes sammensetning og befolkningens kosthold er grunnleggende for utforming
og oppfølging av en helsefremmende mat- og ernæringspolitikk. Dagens system for overvåking av
kostholdet bygger først og fremst på en matvaredatabase og opplysninger om forbruket av matvarer fra tre
typer datasett; matforsyningsstatistikk, forbruksundersøkelser og kostholdsundersøkelser. Det avgis årlig en
vurdering av utviklingen i norsk kosthold i forhold til mat- og ernæringspolitiske målsettinger. Det norske
systemet for overvåking av kostholdet er blitt betydelig styrket i løpet av 1990-årene ved innføringen av
regelmessige kostholdsundersøkelser blant landsrepresentative utvalg av befolkningen i ulike aldersgrupper
og økte ressurser til analyse av næringsinnholdet i matvarer. Det er imidlertid beskjedent sammenlignet med
datainnsamlingen i land som USA og Storbritannia. Det norske overvåkingssystemet er forsatt i en
utviklingsfase, og det må justeres og kompletteres etter hvert. Dessuten vil det arbeides med å kvalitetssikre
Surveillance of the diet in Norway – methods and results.
Nor J Epidemiol
Knowledge about changes in composition and intake of foods, as well as changes in the prevalence of dietrelated
health problems is fundamental for an effective food and nutrition policy. The National Council on
Nutrition and Physical Activity is responsible for evaluating changes in the diet. Annually the Council publishes
reports about trends in the Norwegian diet, and suggests measures to improve the diet. The Council, in
cooperation with the National Food Authority and the Institute for Nutrition Research, University of Oslo,
has established a national food and dietary surveillance system. This system is mainly based on a food
database and food consumption data. The food consumption data include three principally different data
sets: food supplies, household consumption surveys, and dietary surveys. Food supplies have been published
annually since 1952. Household consumption surveys among random nation-wide samples of private
households have been performed annually by Statistics Norway since 1975. Dietary surveys were included
on a regular basis in the surveillance system in 1993 when the first Norwegian nation-wide dietary surveys
among students 13 and 18 years old and the general population aged 16-79 years were conducted. The
second dietary survey among the general population was made in 1997, and the first survey among infants
was performed in 1998-99. The second survey among children 5-13 years is planned for 2000-2001. The
Norwegian surveillance system has been considerably improved during the 1990s. However, the collection
of dietary data is still modest compared to what is done in the USA and Great Britain. The system is
developing, and will be adjusted and supplemented. Quality assurance of methods will be given priority.2000; 10 (1): 31-42.
