(1) To apply the ultrasound technique to measuring the subcutaneous fat thickness in neonates. (2) To test the hypothesis that there is a relationship between the neonatal weight loss and their changes of subcutaneous fat thickness during the same period. (3) To relate the results to the maternal and neonatal data. The thickness of subcutaneous fat layer were measured in 172 infants within 24 hours of birth, on the second and the fourth day from the birth, using then pulsed ultrasound apparatus. Six sites were chosen over the right side of the body; (1) biceps (2) triceps (3) subscapular (4) suprailiac (5) upper breast (6) front thigh. The birthweight, gestational age, some anthropometric data at birth, and maternal characters were also recorded. The ultrasonic pulses were clear enough to read when measuring the subcutaneous fat thickness in the neonates. The mean of the fat thickness on the third day was significantly smaller than that of the day of birth, i.e. the first day and the fifth day, indicating the relationship with the weight loss during the four days after birth . It was obvious that fat thickenss is related with birthweight and not with gestational age. The effects of other elements on the fat thickness are now under analysis.
