A total of 470 pregnant women recorded fetal movement with the fetal movement acceleration measurement recorder weekly after 28\u2009weeks. The ratio of 10\u2010s epochs with fetal movement to all epochs was calculated as the fetal movement parameter. When the parameter was below the 10th percentile of the previously made reference curve, it was defined as decreased movement. Women who showed a decreased movement at least once were classified into a study group, and the other women were classified into a control group.
