Children with failure to thrive are at an increased risk for long-term growth, cognitive, and behavioral complications. Studies have shown that children with failure to thrive during infancy were shorter and lower weight at school-age than their peers. Failure to thrive may also result in children not achieving their growth potential, as estimated by mid-parental height. Longitudinal studies have also demonstrated lower IQs (3–5 points) and poorer arithmetic performance in children with a history failure to thrive, compared to peers receiving adequate nutrition as infants and toddlers. Early intervention and restoration of adequate nutrition has been shown to reduce the likelihood of long-term sequelae, however, studies have shown that failure to thrive may cause persistent behavioral problems, despite appropriate treatment.
