致编辑：我们感谢对我们的文章“胎动频率和相关围产期因素的影响：多中心研究”的回应。首先，我们同意，重要的是要鼓励孕妇报告他们对胎动（FM）质量的看法的变化，例如强度和模式，以防止不良的胎儿结局，正如对我们文章的评论所述。据报道，胎动减少（DFM）与不良的胎儿结局相关2，母亲报告DFM的过度延迟与围产期死亡相关3。我们以前表明，只有11%的死产母亲在24小时内访问门诊部感知DFM 4。因此，我们的目的是在目前的研究中，以评估调频频率的正常范围，使孕妇可以立即报告他们的感知DFM。此外，我们无法建立不良围产期结局发生的临界值，因为我们在本研究中没有考虑结局不良的胎儿病例的FM频率。接下来，我们还担心孕妇可能会将DFM误认为是晚期妊娠。
To the Editor: We appreciate the response to our article," Fetal movement frequency and the effect of associated perinatal factors: Multicenter study" 1. First, we agree that it is important to encourage pregnant women to report changes in their perception of the fetal movement (FM) quality, such as the strength and pattern, in order to prevent adverse fetal outcomes, as the comment on our article stated. It has been reported that decreased fetal movement (DFM) is associated with adverse fetal outcomes2, and an excessive delay in maternal reporting of DFM is related to perinatal death3. We previously showed that only 11% of mothers with stillbirths visited the outpatient department within 24 h of perceiving DFM 4. We therefore aimed to evaluate the normal range of FM frequency in the current study so that pregnant women could immediately report their perception of DFM. In addition, we could not establish a cut off level for the onset of adverse perinatal outcomes due to the fact that we did not factor in the FM frequency of fetal cases with a poor outcome in this study. Next, we are also concerned that pregnant women might mistake DFM in late
