Retrospective cohort study develops a nomogram to predict faltering growth in full-term infants, suggesting early intervention could help.

This research aims to establish a prediction nomogram for faltering catch-up growth in full-term small-for-gestational-age infants before two years old.
Conducted a retrospective cohort study of 1,185 SGA infants from 1996 to 2019 and validated with 294 infants from 2020 to 2023.
Defined faltering catch-up growth as failure to increase length-for-age Z score by ≥0.67 by 24 months.
Used multivariable logistic regression to identify predictors including sex and Z scores for birth weight, length, and target height.
23.6% of SGA infants in the development cohort experienced faltering catch-up growth.
In logistic regression, male sex and lower Z scores for birth weight, length, and target height were significantly associated with faltering growth (all p < 0.05).
The nomogram achieved an AUC of 0.784 in the validation cohort, with a sensitivity of 93% and specificity of 56%.
