The purpose of this study was to determine the onset of fetal movements' perception and to identify parameters that affect this timing.
This was a prospective cohort study including singleton pregnancies that attended routine prenatal care, in a tertiary care center, in northern Greece, between January 2020 and July 2021. We collected data on medical and obstetric history, and invited women to record the time that they perceived the fetal movements for the first time, that being the primary outcome of the study. Furthermore, we studied the associations between this timing and several obstetric and sociodemographic parameters.
In total, 2,009 women participated in the study. The mean gestational age at first perception of fetal movements was 19 weeks (±1.5). This ranged from as early as 14-14 weeks (0.1%) to 24-24 weeks (0.1%). The majority of women (73.3%) reported initial perception of fetal movements between 18 and 20 weeks. Following multivariate logistic regression analysis, we found that nulliparity (OR: 2.607; 95% CI: 1.876-3.622; p<0.001), anterior placental position (OR: 1.918; 95% CI: 1.575-2.336; p<0.001), increasing body mass index (OR: 1.063; 95% CI: 1.040-1.088; p=0.001) and advancing maternal age (OR: 1.062; 95% CI: 1.040-1.084; p<0.001) were associated with a delayed perception of fetal movements. Multiparous women reported the onset of fetal movements almost one week earlier on average (18.6±1.4 weeks) compared to nulliparous (19.4±1.4 weeks; MD: 0.843; 95% CI: 0.718-0.968; p<0.001).
The onset of maternal perception of fetal movements is around 19 weeks and this timing may be delayed by higher maternal age, higher body mass index, nulliparity and anterior placental position.
本研究旨在确定胎儿运动感知的起始时间，并确定影响这一时间的参数。
这是一项前瞻性队列研究，纳入了 2020 年 1 月至 2021 年 7 月在希腊北部一家三级保健中心接受常规产前护理的单胎妊娠女性。我们收集了医疗和产科史数据，并邀请女性记录首次感知胎儿运动的时间，这是本研究的主要结果。此外，我们研究了这一时间与几个产科和社会人口学参数之间的关联。
共有 2009 名女性参与了研究。首次感知胎儿运动的平均孕周为 19 周（±1.5）。这一范围从 14-14 周（0.1%）到 24-24 周（0.1%）不等。大多数女性（73.3%）报告在 18 至 20 周之间首次感知到胎儿运动。经过多变量逻辑回归分析，我们发现初产妇（OR：2.607；95%CI：1.876-3.622；p<0.001）、前置胎盘（OR：1.918；95%CI：1.575-2.336；p<0.001）、体重指数增加（OR：1.063；95%CI：1.040-1.088；p=0.001）和产妇年龄增加（OR：1.062；95%CI：1.040-1.084；p<0.001）与胎儿运动感知延迟相关。经产妇平均报告胎儿运动的起始时间早近一周（18.6±1.4 周），而初产妇（19.4±1.4 周；MD：0.843；95%CI：0.718-0.968；p<0.001）。
母亲感知胎儿运动的起始时间约为 19 周，而较高的母亲年龄、体重指数、初产妇和前置胎盘位置可能会导致这一时间延迟。
