The long-term benefits of early childhood supplementation and the extent to which catch-up growth occurs following linear growth retardation remain controversial.
Stunted children (height-for-age<-2 SD of NCHS references, n=122) recruited from a survey of poor neighborhoods in Kingston, Jamaica, participated in a 2-yr randomized, controlled trial of supplementation beginning at ages 9-24 mo.
A group of 32 non-stunted children from the same neighborhoods was also followed.
Four years after the intervention ended, when children were 7 to 8 y old, there were no effects of supplementation on any anthropometric measure.
From the end of the trial until follow-up, the children who had been supplemented gained 1.2 cm less (P<0.05) than the non-supplemented children, approximately the same amount as they had gained during the trial compared with the non-supplemented children.
After adjustment for regression to the mean, the height-for-age of stunted children (supplemented and non-supplemented combined) increased from enrollment to follow-up by 0.31 Z-score (95% Cl 0.17,0.46).
The height-for-age of the non-stunted children also increased (0.96 Z-score ; 95% Cl 0.70,1.22).
Our results suggest that some catch-up growth is possible even when children remain in poor environments.
Long-term benefits of supplementation to growth may not be achieved when intervention begins after age 12 mo in children who have already become undernourished.
