Abstract

Calculation of weight gain velocity is used to guide nutrition and fluid management practices in neonatal intensive care units. Calculations over short time periods may be more responsive to management changes, but less precise. Weight gain velocity calculated over 5 to 7+ days have lower variability and less noise than shorter periods.

Keywords: growth; infant feeding; nutrition.
