SAMMENDRAG
I USA er det anslått at 30% av alle dødsfall som skyldes kreftsykdom kan tilskrives kosthold i voksen alder
(inkludert kostholdets betydning for overvekt).
4 Fra Statens helseundersøkelser sine hjertekarundersøkelser
i Finnmark, Sogn og Fjordane og Oppland i 1977-83, foreligger data om kosthold for vel
50 000 menn og kvinner i alderen 16-56 år. Kopling mot Kreftregisteret og Statistisk sentralbyrå gir oss
mulighet til å se nærmere på sammenhengen mellom kosthold og risiko for kreft i en kohortstudie med
komplett oppfølging med hensyn på forekomst av kreft, død og emigrasjon. I henhold til kontrakten om
bruk av den koplete datafila, studerer vi i dette prosjektet sammenhengen mellom kosthold og risiko for
kreft i magesekk, bukspyttkjertel, livmorhals, prostata, lunger og hud (malignt melanom). Den statistiske
styrken i epidemilogiske studier som denne, samt hvilken betydning målefeil i kostholdsvariablene har for
risikoestimatene og den statistiske styrken, blir også vurdert. Denne artikkelen gir en nærmere presentasjon
av prosjektet og de metodene som benyttes.

NGLISH SUMMARY
The relationship beteen dietary habits and the incidence of cancer is studied in 50,000 Norwegian men and
women aged 16-56 years attending a Norwegian health screening in 1977-83. Linkage to the Cancer
Registry of Norway and the Central Bureau of Statistics of Norway ensure a complete follow-up until 31
December 1992. The cancer sites included in this project are the stomach, pancreas, cervix, prostate, lung
and malignant melanoma. Diet was recorded on a semi-quantitative food-frequency questionnaire at the
time of screening, and intake of energy and fats are estimated. The attenuation of effect estimates due to
measurement errors in the dietary variables will be investigated, as well as the power of the study. The project
is not finished yet, and this paper gives a description of the project and the methods of statistical
analysis. The first results were published in the International Journal of Cancer earlier this year.
