Abstract

Based on the service contract OC/EFSA/DATA/2015/03 CT1, the FinDiet 2017 Survey in adults (18‐64 years old) and elderly (65‐74 years old) was carried out in compliance with the EU Menu methodology. Altogether 10305 subjects were originally invited to participate in the FinHealth Study and the dietary data was collected in a sub‐sample of about 30% (n= 3099) between January‐October 2017. Background questionnaires and a food propensity questionnaire were answered by the participants of the dietary survey. The weight and height were measured or self‐reported. The dietary data was collected from two non‐consecutive days by applying the open‐ended 24‐hour dietary recall method both as computer assisted face‐to‐face personal and telephone interview methods using the in‐house developed software Finessi, which applies the National Food Composition Database Fineli®. The Finessi software was updated to cover the collection of mandatory FoodEx2 facet descriptor information.Of the eligible sample, 57% provided an acceptable first 24‐hour recall interview. Eventually, both interviews were acceptably completed by 1655 participants (53% response rate). Several quality assurance protocols were put in place. The methodology was piloted in August‐September 2016 and the protocols were finalized based on the results of the pilot study. A two‐week training of the dietary interviewers took place prior to the main data collection. The quality assurance of the survey was based on detailed study protocols, regular meetings of the survey management and planning groups, careful training of the personnel, several quality checks during the data collection and careful cross‐checking of the data collected. The extents of under‐reporting among full participants were 21% (personal interview) and 18% (telephone interview), respectively.
