The Northern Sweden Diet Database, NSDD

The NSDD is a uniform database integrating self-reported questionnaire data on diet from two large research projects in Northern Sweden; DietVIP within the Västerbotten Intervention Project (VIP) and DietMON within the Northern Swedish MONICA project.

Information on the habitual eating habits in the region of Northern Sweden has been collected since 1985, by means of a semi-quantitative food frequency questionnaire.

Both DietVIP and DietMON are ongoing research projects, and the NSDD is thus regularly updated with new data from VIP and the recurrent MONICA screenings.

The development of the NSDD, including the integration of dietary data collected in DietVIP and DietMON and validation of food frequency questionnaires and diet variables have been supported by the Swedish Research Council (VR), the Swedish Council for Working Life and Social Research (FAS), and the Swedish Cancer Society.

STROBE criteria improve research on nutrition and health

STROBE (Strengthening the Reporting of Observational Epidemiology statement), is a collaborative initiative that aims at improving the reporting of epidemiological research.

STROBE has been adapted in different fields of epidemiological research and is supported by a growing number of journals. STROBE-nut,, is an adaptation for nutrition epidemiology. We strongly recommend that all users of the Northern Sweden Diet Database follow the STROBE-nut criteria:
