Introduction. Changes occurring over the years in environmental conditions and in organism’s adaptability contribute to changes in the human morphological and functional phenotype. Purpose of the study. Assessment of progress in body weight, body height, chest circumference, as well as Quetelet II (BMI), Rohrer, and Marty indexes in children and adolescents from Rzeszów, aged 4-18, and changes in the period of the recent 35 years. Material and methods. The total of 1,563 children from Rzeszów were examined in 2013/2014. Measurements were carried out to identify body weight, body height, chest circumference; based on that Quetelet II, Rohrer, and Marty indexes were calculated. Results. The findings, presented in tables and figures, have been interpreted. Conclusions. Somatic growth in the examined population is consistent with generally recognized regularities. The secular trend continues in the period of 35 years. It is impossible to make an explicit claim regarding stabilization of growth during the last 10 years.
