Growth pattern of intrauterine growth retarded (IUGR) babies in first nine months of life.

Forty-one full term intrauterine growth retarded (IUGR) babies of different maternal etiologies viz. maternal undernutrition (12), small maternal size (12), toxaemia of pregnancy (9) and idiopathic (8) were studied for growth pattern during first 9 months of life. Eighteen fullterm and 11 preterm who were appropriate for gestational age served as controls. These mothers were comparable for age, parity, socioeconomic status, weight and height (except in small size mothers), haemoglobin and plasma albumin (except in undernourished group). The various anthropometric parameters studied were weight, crown-heel length, head circumference, their velocities and ponderal index. The IUGR babies of undernourished mothers had lowest means for weight, crown-heel length and skull circumference. The babies of small sized mothers suffered most in crown-heel length followed by weight. The head growth was not affected in these babies. The IUGR babies of mothers with toxaemia of pregnancy demonstrated a catch up growth for all three parameters. The IUGR babies of idiopathic group showed a spurt in weight gain around 3 to 6 months and a similar spurt for crown heel length and head circumference was observed between 6 to 9 months of age. These babies were close to IUGR babies of mothers with toxaemia of pregnancy at 9 months. The preterm AGA babies also demonstrated a catch up growth for the weight, crown heel length and circumference.
