The interaction of psychosocial, behavioral, and physiologic factors can be tremendously complex. Because there is no uniformly accepted definition for FTT, the incidence cannot be precisely determined. However, in high-risk populations (low-birth weight infants, children living in poverty), estimates run as high as 5% to 10%. While the disorder is primarily managed in the outpatient setting, more challenging or severely affected patients or those whose safety is in question may require hospitalization. Thus it is critical for pediatric hospitalists to have a clear approach to this diagnostic challenge.
