Conclusions
This study found that although, on average, lower EFW percentiles on the
INTERGROWTH-21st and WHO population fetal growth
references are associated with increased risks of adverse child
neurodevelopment at kindergarten age, they are not accurate
individual-level predictors of adverse child development, across a broad
range of possible percentile cut-points. Our findings support recent
calls to shift away from the reliance on fetal size percentiles for
identifying growth restriction, and adopt a more comprehensive,
multi-faceted approach to risk assessment.
