Catch-up growth: implications for the preterm and term infant

Catch-up Growth

3 rowth Failure in the Preterm Infant : an We Catch Up ? nna

ostnatal growth failure is extremely common in the very low birth weight and extremely low birth eight infant. Recent data from the National Institute of Child and Human Development (NICHD) eonatal Research Network indicates that 16% of extremely low birth weight infants are small for estational age at birth, but by 36 weeks corrected age, 89% have growth failure. Follow-up at 18 to 2 months co...

Catch-up growth.

Catch-up growth, defined as growth velocity above the statistical limits of normality for age or maturity during a defined period of time, is distinguished from compensatory growth since it makes up for a potential loss rather than an actual loss and is seen in the whole body as opposed to specific organs. The cellular explanation for catch-up based on the work of Winick is described and a rece...

Growth plate senescence and catch-up growth.

Longitudinal bone growth is rapid in prenatal and early postnatal life, but then slows with age and eventually ceases. This growth deceleration is caused primarily by a decrease in chondrocyte proliferation, and is associated with other structural, functional, and molecular changes collectively termed growth plate senescence. Current evidence suggests that growth plate senescence occurs because...

Nutritionally-Induced Catch-Up Growth

Malnutrition is considered a leading cause of growth attenuation in children. When food is replenished, spontaneous catch-up (CU) growth usually occurs, bringing the child back to its original growth trajectory. However, in some cases, the CU growth is not complete, leading to a permanent growth deficit. This review summarizes our current knowledge regarding the mechanism regulating nutrition a...
