The fetal weight below the 10th percentile for gestational age is been accepted as IUGR generally. But there is no international consensus about the definition . Lubchenco and co-workers had been definated the IUGR status in 1963 and published the details from Denver. Lubchenco and other authors have developed or changed the definition by their own examinations in consecutive years. The statements of; Fetal weight below the 3th percentile. below 5th or below IStli percentile, fetal weight below two stan-dart deviations for normal gestational age, head circumference / abdominal circumference > 2 standart deviations, ponderal index (birth weight - gr / heigt — cm') below 10th percentile for geslational age , fetal abdominal circumference .£ two standart deviations for gestational age, are the different definitions ot IUGR. Small tor geslational age (SGA) is a different terminology for that situation which has been used by Lubchenco and Battaglia in 1967 for the first time.
Lubchenco's results from examination on white infants in 1963 has been used for over 30 years as standart datas in USA. Brenner and colleagues used white and black infants delivered in Cleveland and North Carolina in 1976 and Williams used live births in four ethnic groups in California to examine fetal growth curves and found that fetal growth may vary in different ethnic and religious groups from each other . Ott used postnatal assesment of infants born in St Louis in different national groups and found that each ot these growth curves were different from each other in different populations. For that reason they were not considered a certain growth curve necessarily representative of "the entire population. In LISA the fetal growth datas derived from Alexander ' s nationwide basis examination in 1996 and in Canada Ar-buckle ' s nationwide basis examination in 1993 are being used in these countries.
