comparison of growth charts of 1-36 month old tehrani children with the n.c.h.s.l curve

during a historic prospective study, measurements of weight, height and head circumferences were carried out in a group of 393 tehrani boys and girls between the first and 36th month of life and measurements were plotted over the n.c.h.s. curves. these children belonged to middle and high-class literate families who were able to understand and follow the medical advice given by their private pediatricians. results of this study (table i and figs. 1-6) indicate that the trend of growth of this sample of middle and high-class tehrani children does not differ from n.c.h.s. standards, provided that the parents understand and follow the instructions given with regards to diet, timing, and type of introduction of foods as well as hygienic and preventive measures to be taken.
