Nonorganic failure to thrive: a theoretical approach

Nonorganic failure to thrive (NOFTT) is a significant health problem of infancy. Although NOFTT is thought to be a result of multiple factors, exactly what these factors are is unclear. Explaining the development of NOFTT has been hindered by a lack of a theoretical approach. The purpose of this article is to provide a review of the literature and the discussion of a theoretical framework to guide future research in the area of NOFTT.
