VERY LOW BIRTH WEIGHT (VLBW) POSTNATAL GROWTH CHARTS
This website allows the user to enter the Birth Weight, Birth Length and Birth Head Circumference of a 501-1500 gram infant and to construct individualized, expected growth curves based upon the NICHD Neonatal Research Network Growth Observational Study (Ehrenkranz, et al. Pediatrics, 1999; 104:280-289). Note that while these expected growth curves are based upon data collected from a large heterogenous population and reflect nutritional practices common in 1994-95, the "expected" curve may not represent optimal growth.
