Body height, weight, and Body Mass Index - magnitude and pace of secular changes in children and adolescents from Kraków (Poland) between 1983 and 2020.

In conclusion, the rapid increase of body height in the years 1983-2000 and later secular increase of the body mass and BMI in 2000-2010 were probably associated mainly with significant socio-economic progress of the country. On the other hand, deceleration of those trends in 2010-2020, especially in regards to body height, may be associated with reaching the maximum genetically attainable body height in the examined population.
