Several follow-up evaluations have found that by school age, most children with a history of faltering growth have normal weight although many continue to be shorter than age-matched peers.[39]Waterlow JC, Buzina R, Keller W, et al.

When cognitive and academic performance have been considered, by school age, children with faltering growth recruited from primary care or community sites had average IQ scores that were approximately 4 points lower than those of children with a history of adequate growth.[14]Wright CM.

These findings suggest early faltering growth may result in a small, though potentially important, impact on cognitive performance, but not the severe deficits implied by earlier studies that focused on hospitalized children.
One follow-up of children with faltering growth in the first 2 years of life found that at 8 years of age, children with a history of faltering growth were shorter, thinner, and had lower math scores than children with no history of faltering growth.[46]Black MM, Dubowitz H, Krishnakumar A, et al.

However, there were no group differences in IQ, reading, or behavior problems. Home intervention partially buffered the negative effects of faltering growth on height, BMI, math performance, and school behavior at 8 years of age.[46]Black MM, Dubowitz H, Krishnakumar A, et al.

One of the only studies to follow children into adolescence found that the long-term educational effects of faltering growth were associated with the confounders, suggesting that faltering growth in the context of poverty carries risk, but in a resource-rich context, faltering growth is not a major cause for concern.[47]Holme AR, Blair PS, Emond AM. Psychosocial and educational outcomes of weight faltering in infancy in ALSPAC. BMJ Open. 2013;3:e002863.
