Growth is an increase in the physical dimensions and its result is a quantitative
change in the body. Development is a progressive increase in the skills and functional capacity of
a child and its result is a qualitative change in a childיs function.
Methods: This investigation was a descriptive, decompositive, and observative study, which
was performed on a random group of 5,378, 6- to 12-year-old children in 45 schools in the urban
population of Mashhad, Khorasan Province, Iran.
Results: The height and weight averages of the studied children were more than the averages
of Nelsonיs Textbook of Pediatrics. However, as age increased, the height and weight averages of
the studied children became less than the averages of Nelson.
Conclusion: To accelerate childrenיs physical growth, we should closely follow up on factors
which could fortify children and affect their growth.
