Impact of the Intervention on Children’s Height, Weight, and Head Circumference During the First 24 Months of Age
INTERACTION
The mean growth of the children was within the normal reference range over the study period (Table We found that the intervention group and time had an interaction effect on the child’s height-for-age SD-score (intervention group × time effect, Interaction between the intervention group and time after birth on the children’s growth markers over the study period. Figure shows the adjusted mean (standard error) for (A) height-for-age SD-score, (B) weight-for-height%, (C) weight-for-age SD-score, and (D) head circumference-for-age SD-score derived from analysis of covariance for repeated measurements. Analyses were adjusted for maternal smoking status before pregnancy and for the child’s birth weight. Significant interaction between intervention group and time in the height-for-age SD-score; in the subsequent pairwise interaction effect comparisons, the difference was evident between the probiotics+fish oil group and placebo+placebo group (group × time effect,
