背景：我们的目的是澄清小于胎龄儿（SGA）是否与胎动（FM）减少有关，即使在没有缺氧的情况下。方法：（1）将13例SGA胎儿的FMs参数与64例正常孕妇的FMs参数作正常参考值曲线比较，并与正常孕妇的FMs参数进行比较。(2)结果：SGA组共获得38个数据记录，其中SGA组有10个数据记录，SGA组无1个数据记录，SGA组无1个数据记录。(1)运动阳性10秒时相的比率，有14个（36.8%）记录值低于正常值的10%。至于平均变动次数，有13次（34.2%）的变动幅度低于10%。平均无运动次数、平均无运动持续时间和最长无运动持续时间分别有12次（31.6%）、13次（34.2%）和15次（39.4%）超过正常值的90%。(2)SGA是一个因素，减少了积极的时期比率和平均运动数量，增加了平均数量和持续时间，以及最长的非运动periods.Conclusions：SGA是与减少运动，即使在没有缺氧。
Background:Our purpose was to clarify whether small-for-gestational (SGA) infants is associated with a decrease in fetal movements (FMs) even in the absence of hypoxia. We used a fetal movement acceleration measurement (FMAM) recorder, which enabled counting gross FMs for hours at a time.Methods: (1) Parameters of FMs for 13 women who delivered SGA infants were plotted over normal reference value curves made from 64 normal pregnant women in another study. (2) Linear regression analysis was conducted for the women with SGA infants and the normal pregnant women.Results:Thirty-eight data recordings were available in the SGA group. (1) For the ratio of movement positive 10-s epoch, 14 recordings (36.8%) were below 10% of the normal values. For an average number of movements, 13 (34.2%) were below 10%. Regarding average number, average duration, and longest duration of non-movement period, 12 (31.6%), 13 (34.2%), and 15 records (39.4%) were above 90% of the normal values, respectively. (2) SGA was a factor that decreased the positive epoch ratio and the average movements number, and increased the average number and duration, and the longest duration of non-movement period.Conclusions:SGA is associated with decreased movements even in the absence of hypoxia.
