After taking inclusion and exclusion criteria into account, growth pattern of the infants' height, weight and head circumference within first 5-year of life was compared to that of normal children of WHO in terms of age and sex in 3,15,50,85, 97 percentiles.

Results: The study results revealed that pattern growth of height, weight and head circumference within girl patients was developed parallel with the growth pattern of healthy girls of WHO. Within the boys, linear pattern growth after 36 months, weight growth after 9 months and head circumference growth at 24 months was similar to the growth pattern of healthy boys of WHO.
