Nutritional Intake Influences Zinc Levels in Preterm Newborns: An Observational Study.

ABSTRACT: (1) Background: Zinc is a key element for protein synthesis in preterm newborns. Early aggressive nutrition, promoting protein synthesis, may increase zinc consumption; (2) Methods: We performed a prospective observational study, to assess the relationship between early macronutrients intake and serum zinc levels, in preterm newborns with Gestational Age (GA) of 24-35 weeks, consecutively observed in Neonatal Intensive Care Unit (NICU). (3) Results: We enrolled 130 newborns (GA 31.5 ± 2.8). A significant negative correlation between serum zinc level at 28 days of life and energy (r -0.587, p < 0.001) and protein intake (r -0.556, p < 0.001) in the first week of life was observed. Linear regression analysis showed that zinc levels depended on energy (β -0.650; p < 0.001) and protein (β -0.6
