Weight gain in relation to IGF-I and body composition in preterm infants. A, Change in IGF-I in relation to change in weight SDS up to 36 weeks PMA (r = 0.62 [95% CI, 0.46-0.74; P < 0.001]). B, Change in weight SDS from 30 weeks PMA onwards in relation to fat free mass and fat mass at term equivalent age. Partial correlation with fat free mass (r = 0.72 [95% CI, 0.56-0.82; P < 0.001]); partial correlation with fat mass (r = 0.77 [95% CI, 0.65-0.86; P < 0.001]) Correlations were controlled for gestational age at birth and postmenstrual age at time of body composition measurement. C, Change in weight SDS from 30 weeks PMA onwards in relation to fat free mass percentage at term equivalent age. Linear regression model: R2: 0.45 P < 0.001, B for change in weight SDS −54.0 (95% CI, −72.0 to −35.9, P < 0.001) (gestational age at birth and postmenstrual age at the time of body composition measurement were entered in the regression model as covariates). Abbreviations: PMA, postmenstrual age.
