Abstract

Animal studies have shown that maternal protein deficiency during pregnancy affects fetal birth weight. This study has examined whether or not the fetal birth weight of full-term newborns has any relationship with the acute protein nutrition status of the mother. Protein nutrition status was assessed by measuring the plasma transthyretin (prealbumin) concentrations. Plasma transthyretin concentrations (mean +/- SE) from the cord blood of 20 newborns (10.9 +/- 0.5 mg/dl) were significantly lower (p < 0.000000001) compared with respective maternal concentrations (17.8 +/- 0.8). There was a significant correlation of transthyretin concentrations between mother and newborns (r = 0.61, p < 0.005), and of newborn birth weight with plasma transthyretin concentrations of newborns (r = 0.57, p < 0.01) and mothers (r = 0.51, p < 0.03). This study documents a relationship of fetal birth weight with maternal and newborn plasma transthyretin concentrations.
