The aim of the study was to evaluate the nutritional status of 16-18-year-old youth, from the Kuiavia-Pomerania region, on the basis of somatic parameters. The research included 155 girls and 137 boys, attending second and third classes of secondary schools with vocational or general education profile. The nutritional status evaluation was made on the basis of measurements of: body mass and height, skinfolds thickness, arm, waist and hips circumference and the calculated indices: BMI and AMC. The results obtained were interpreted individually with reference to somatic development indices worked out for Warsaw adolescents by Palczewska and Niedźwiecka [2001]. The mean values of somatic parameters obtained in the study for the youth of the Kuiavia-Pomerania indicate proper body sizes, i.e. body height and mass according to age and mass-to-height ratio. Moreover excessive adiposity and too low muscle mass of the studied youth were stated. Such disproportions in body composition were also revealed for youth with undernutrition and overweight. The results obtained suggest the occurrence of irregularities in eating habits and/or improper way of life of the youth, including low physical activity.
