Fruits and vegetables are crucial for children and adolescents, as they contain many vitamins and minerals needed for their development and daily functioning. The data for the master’s thesis were obtained within the School Fruit and Vegetable Scheme (SŠSZ) 2015/2016, which has been implemented by the National Institute of Public Health (NIJZ) in accordance with the EU Regulation in the Republic of Slovenia. The sample of our research were pupils from the 6th and 8th grades of the ten elementary schools in Slovenia (departments A), which were between 11 and 15 years old in the school year 2015/2016 (N = 182). Data about the socio-economic status and dietary habits of the subjects were obtained through a questionnaire containing questions about their socioeconomic status and questions about the frequency of consumption of individual foods (the Food Frequency Questionnaire (FFQ)). Their socio-economic status (SES) was assessed in accordance with the International Health Education and School-aged Children (HBSC) study protocol and identified with a scale called FAS (Family Affluence Scale). The fieldwork of the study was carried out twice in the spring and autumn of the school year 2015/16. Data about the consumed amounts of foods were obtained with a 24h-recall method and assessed with a computer program Open Platform for Clinical Nutrition (OPKP). According to our results, socio-economic status did not affect the consumption of fruit and vegetables. The gender and age of adolescents also did not affect the average weekly amount of consumed fruit and vegetables.
