Abstract
In order to evaluate the determinants of high and low ponderal indices in triplets, we analyzed prospectively collected data from a cohort of 2181 triplet births. Low and high neonatal ponderal indices (birth weight/ [length] [3]) were defined as below or above 1 SD from the mean. The mean ponderal index was of 2.4+=0.4. At 30-31 weeks, there were significantly more infants with a low ponderal index; after 33 weeks, more infants were born with a high index. Birth weights of infants with a high index were significantly higher throughout the entire range of gestational ages, whereas their lengths were significantly smaller. Both birth weights and infant length had significant correlations with gestational ages for infants with a low (R[2]=0.97 and R[2]=0.94, respectively) as well as with high ponderal indices (R[2]=0.95 and R[2]=0.94, respectively). The regression analyses suggest, however, different patterns for infants with low or high ponderal indices.
