Abstract

Background

Active fetal movements (AFMs) are a sign of the well-being of the baby during pregnancy and suggests the integrity of the cardiovascular, musculoskeletal, and nervous systems of the fetus. The abnormal perception of AFMs is associated with an increased risk of adverse perinatal outcomes such as stillbirth (SB) and brain damage. Several definitions of “ decreased fetal movements” have been proposed, but none of them has been universally accepted. The aim of the study is to investigate the perinatal outcomes in relation to AFMs frequency and perception in term pregnancy with an ad hoc questionnaire administered to the women before delivery.

Study design

This was a prospective case-control study on pregnant women at term referring to the Obstetric Unit of the University Hospital of Modena, Italy, between January 2020 and March 2020. A validated questionnaire was administered to women who agreed to participate in the study. Therefore, women were subdivided into the case and control groups: cases included women who experienced adverse perinatal outcomes (APO) such as perinatal mortality (SB and early neonatal mortality), operative delivery (cesarean section or vacuum) due to fetal distress, Apgar 5’ < 7, neonatal resuscitation at birth and NICU Admission, while controls were women who experienced delivery and birth without APO in the same period.

Results

Seventy-seven cases and 178 controls that compiled the questionnaire were included in the analysis. Characteristics significantly associated with APO were low education (OR 1.57, CI 95% 1.11–2.22), nulliparity (OR 1.76, CI 95% 1.20–2.58), obesity (OR 1.55, CI 95% 1.10–2.17), neonatal male gender (OR 1.92 CI95% 1.33–2.78) and centile at birth (< 10° and >90°) (OR 2.77, 95%CI 2.17, 3.55). There was no association between any answer about strengths, frequency and vigor of perceived fetal movements and APO. Even any maternal perception of fetal hiccups or uterine contractions wasn’t associated with APO. On the other hand, women who referred to frequent change positions during sleep (OR 1.55 CI95% 1.05–2.30) and women who snore (OR 1.43 CI95% 1.01–2.05) showed a statistically significant increase of APO.

Conclusions

Our data confirm the significant association between modifiable risk factors (such as obesity and low education) and APO. Thus, healthcare providers should be aware of the importance of intervention in reducing obesity, therefore snoring and related sleep apnea syndrome. Finally, changing position during sleep while not the perception of modified/reduced fetal movements significantly could induce the worst obstetric outcomes.
