Abstract Maternal anthropometric changes are rapid during pregnancy and reflect increments in maternal and fetal tissues. These dynamic changes in body composition and shape during pregnancy are associated with maternal and fetal outcomes and are often monitored with simple tools such as a flexible tape for quantifying selected circumferences.

Abstract Among infants born very preterm (≤32 weeks’ gestation), we compared weight-for-age ≤10th percentile (10%ile) at 36 weeks to malnutrition guidelines using z-score changes and evaluated predictors of malnutrition. Infants (extremely low birthweight (ELBW) n = 699; very low birthweight (VLBW) n = 878) were classified using (1) ≤10%ile and (2) malnutrition categories with z-score changes. Multiple logistic regression identified predictors of malnutrition.
