Abstract
The Slovenian national food consumption survey in adolescents, adults and elderly was a part of the third Slovenian national dietary survey, named SI.Menu 2017/18, with the fieldwork taken place in 2017‐2018. The methodology of the survey followed the EFSA EU Menu guidance and specifications in the contract. Individuals were randomly selected from the Slovenian Central Register of Population following a two‐stage stratified sampling procedure. Dietary survey sample was at population level representative of gender and age classes (10‐74 years old). The participation rate to the survey was 62 %. For 1319 individuals a fully completed data were collected of which 484 were adolescents, 387 adults and 450 elderly. Data collection period was divided into four quarters (3‐monthly samples) and equal distribution of all week and weekend days in order to incorporate seasonal effects and day‐to‐day variation in food consumption was employed. Information on food consumption was collected with two non‐consecutive 24‐hour dietary recalls (using the OPEN dietary software) by interviews. This was complemented with a food propensity questionnaire. In addition to food consumption data, information concerning eating habits, consumers habits, food allergy, using food supplements, on life‐style, physical activity, socio‐demographic and socio‐economic status, and health was collected. The food consumption data was also coded according to the FoodEx2 classification and will be included in the EFSA Comprehensive European Food Consumption Database. Body mass and height were measured. In addition, body composition was also measured in adults and elderly by using impedance analyser. Data from the survey will be very valuable for national risk assessments, nutritional studies, assessment of changes in dietary patterns, and the development and evaluation of nutrition or health policies.
