摘要：Maintenance of proper health and prevention of diseases of civilization are now significant public health problems. Nutrition is an important factor in the development of youth,as well as the current and future state of health. The aim of the study was to show the benefits of the application of cluster analysis to assess the dietary habits of high school students. The survey was carried out on 1,631 eighteen-year-old students in seven randomly selected secondary schools in Bialystok using a self-prepared anonymous questionnaire. An evaluation of the time of day meals were eaten and the number of meals consumed was made for the surveyed students. The cluster analysis allowed distinguishing characteristic structures of dietary habits in the observed population. Four clusters were identified,which were characterized by relative internal homogeneity and substantial variation in terms of the number of meals during the day and the time of their consumption. The most important characteristics of cluster 1 were cumulated food ration in 2 or 3 meals and long intervals between meals. Cluster 2 was characterized by eating the recommended number of 4 or 5 meals a day. In the 3rd cluster,students ate 3 meals a day with large intervals between them,and in the 4th they had four meals a day while maintaining proper intervals between them. In all clusters dietary mistakes occurred,but most of them were related to clusters 1 and 3. Cluster analysis allowed for the identification of major flaws in nutrition,which may include irregular eating and skipping meals, and indicated possible connections between eating patterns and disturbances of body weight in the examined population.
