Northern Sweden Diet Database (NSDD)

Northern Sweden Diet Database (NSDD) is a database with harmonised dietary data from Northern Sweden Health and Disease Study (NSHDS); from the two populationbased cohorts ”Västerbotten Intervention Programme” och ”the MONICA-study in northern Sweden”. Information is collected by a validated, semi-quantitative, food frequency questionnaire (FFQ). Data collection is done by identical instrument and in the same manner in the two projects. The FFQ has three main sections: portion size indication for staple foods, intake frequencies, and dietary supplements. Some information on dietary and meal regimens is available. In addition to information on intake frequencies of single food items or food groups, estimated energy and nutrient intake. The Section of Biobank and Registry Support (BRS) adminstrates the database. The Västerbotten Intervention Programme (VIP) och the MONICA-study are population based projects studying life habits in the population and to reduce the incidence of cardiometabolic diseases. Detailed information NSDD can be found at the website. https://www.umu.se/brs/provsamlingar-och-register/kostdatabasen The dataset growths by approximately 5000 observations per year and the proportion with repeated observations increases. By January 2016, the combined VIP-MONICA diet dataset includes 121,996 unique subjects (equal proportion men and women) with at least one visit and a diet recording. Of these 8.2% are excluded because of incomplete food intake data, extreme (highest and lowest 1%) food Intake levels (FIL), extreme energy intakes (lowest 1% and >5,000 kcal). Nearly 40% have a second 10-year follow up and 7% a third 10-year follow-up. Intakes are reported on a fixed 9-level scale: never, a few times/year, 1-3 times/month, 1 time/week, 2-3 times/week, 4-6 times/week, 1 time/day, 2-3 times/day, ≥4 times/day. Variables in the dataset: 64-84 food items, 65 nutrients including alcohol, 12 on supplements, 3 diet indexes, In addition, some hundred variables on medical status, socio-economy, tobacco use, physical activity, etc. can be linked from VIP and MONICA. Also, blood samples from the participants are stored at Biobanken norr.
