The aim of the questionnaire survey undertaken in autumn 2003 among 449 pupils aged 13-15 was to assess the frequency of occurrence of snacking, to describe food eaten as snacks and to define factors determining snacking habit. Snacking habit occurred among more than 90% of the respondents. Sweets were indicated by the greatest number of population as snacks. More girls than boys ate fruits, chocolate, candies and lollipops for snacking. Simultaneously more boys than girls consumed doughnuts and buns. The greater number of main meals was associated with more frequent consumption of snacks.
