The preferences and frequency of consumption of milk and its products were evaluated among school children together with determining the significance of factors affecting the choice of the products. The studies were carried out among 1498 school children (820 girls and 678 boys aged 15 to 19 years) from selected regions of northern, central and eastern Poland. The preferences were determined for 13 groups of dairy products by test method with a 5-point hedonic scale. For the same groups of products, the studies on consumption frequency were conducted using a 5-point scale. The significance of factors affecting the choice of the analysed products was determined for their 13 groups by the test based on a 3-point hedonic scale. The dairy products that were preferred the most and consumed most frequently by school children included fruit fermented milk beverages and ripening cheeses. Milk was less preferred though it took the first place in ranking the consumption frequency. The preferences of individual dairy products and the frequency of consumption were significantly correlated for the groups of boys and girls. The factors considered in the choice of dairy products included, above all, the quality factors of the product, in this sensory properties, and to a lesser degree the nutritional value. The sex was of minor importance to the significance of choice factors.
