The message to pregnant women should be that FM counts
in normal pregnancies remain constant throughout gestation
when measured during active periods. The currently best-founded definition of DFM—the ‘2-hours alarm’—performed
poorly for screening purposes, indicating the need
for further refinements. The focus must remain on what
truly constitutes DFM in the individual pregnancy, and
what patterns of FM are associated with fetal growth restriction
and other adverse outcomes.
