9:  Failure to Thrive

Chapter 9 Overview

This chapter will discuss the indicators that an infant or child may experience if he/she is suffering from failure to thrive.

Current Definitions

Failure to thrive is a non-diagnostic term for an infant or child who fails to gain in weight and/or length and/or head size and/or development.

Non-organic failure to thrive is a specified medical diagnostic term for an infant or child who has a documented lag of two standard deviations in weight, as well as one standard deviation in one of the following parameters:  height, head size and/or development.  The lag must be related to environmental disruption and must improve when the disruption is eliminated.  By definition, there must be an absence of organic disorders to explain these deviations.

Criteria for non-organic failure to thrive include:

Failure to thrive may be classified as organic, non-organic, or mixed organic and non-organic.  A diagnosis of mixed failure to thrive would apply in cases where the child had a disease with secondary organic psychological reaction. 

Other terms used synonymously for non-organic failure to thrive include:

Non-organic failure to thrive is an interactional disorder in which parental expectations, parental skills, and the resulting home environment are intertwined with the child’s developmental capabilities.  In some instances it is related to child abuse or neglect.  It can be characterized by physical and developmental retardation associated with a disturbed parent-child relationship.  These children are slow to develop and learn, are physically small, and have flattened emotional responses, even to pain.

Family Dynamics Frequently Associated with Failure to Thrive:

Indicators in the Child:

Sleep Disorder in Non-Organic Failure to Thrive

Studies of failure to thrive children show they suffer from sleep deficiencies.  They are often up at night, searching for food and water or roaming around the house.  Some studies suggest poor sleep may be one of the factors causing growth retardation.  The children may forage for food with constant vigilance required for self-preservation.  Researchers believe the tactics used by the child to avoid abuse positively reinforces poor sleep.  The children may feel they have to be constantly aware of their surroundings to be safe.  In sleep, they cannot be safe.  When the children are removed from the existing home environment, their poor sleep habits disappear.

Pysical Findings

Children with non-organic failure to thrive have failure to gain or maintain weight in first 12 months (50% in first six months).  They show an inadequate weight gain starting at birth.  After the first year, their primary deficit is in the long bone growth.  Also present is vasomotor instability, manifested by blue and cold hand and feet, small ulcers, and early gangrene.
