The families of children who fail to thrive: preliminary investigations of parental deprivation among organic and non-organic cases

A majority of cases of failure to thrive (FTT) do not have a known organic etiology. Social and psychological determinants are sought for these "non-organic failure to thrive" (N-O FTT) cases. Social and psychological differences between non-organic and organic cases are also explored here. With the introduction of the term, "maternal deprivation," medical practitioners have implicated mothers' deficiencies as instrumental in the etiology of N-O FTT. However, these mothers are themselves usually deprived. Lack of cooperation in childcare by both parents is noted when classic clinical cases are reviewed. We suggest that the concept, "parental deprivation," provides a more accurate model. Preliminary research findings support our hypothesis that mothers of FTT infants do not have good social support networks. Teen motherhood and socioeconomic status also appear to be important, but not necessary as determinants. An unexpected finding is that there are few differences in the social deficiencies of families of N-O FTT infants as compared to those failing for organic reasons. Two unanticipated findings appear noteworthy. First, infants failing for organic reasons are significantly smaller and thinner at birth, independent of pregnancy complications or prematurity. Second, infants failing for non-organic reasons are more likely to present during the period of infant-caretaker role development and less likely in the later toddler stage. Additional research into the feasibility of strengthening family supports as a basis of intervention is recommended.
