Background Several studies exploring the associations of reduced fetal movements (RFM) with adverse perinatal outcomes have been published in recent years. Objectives To synthesise the evidence on pregnancy, birth and neonatal outcomes in women who presented with RFM to ascertain associations between RFM and pregnancy outcomes. Search Strategy PubMed, EMBASE, CINAHL complete, Maternity and Infant Care, PsycINFO, and Science Citation Index databases were searched from inception dates to 8th July 2021 Selection Criteria Non-randomised studies involving pregnant women ≥24 weeks’ gestation, who presented with a primary complaint of RFM compared to women who did not present with RFM were included. Data Collection and Analysis Two authors independently extracted data and assessed risk of bias using the Quality in Prognosis studies (QUIPs) tool. Data were meta-analysed using a random-effects model and presented as Odds Ratios (OR) or Standard Mean Differences (SMD) with 95% Confidence Intervals (CI). Main Results Thirty-nine studies were included. Women with RFM were more likely to have a stillbirth (OR 3.44, 95% CI 2.02-5.88) and small for gestational age (OR 1.36, 95% CI 1.15-1.61) when compared with women who did not have RFM. Associations were also found for induction of labour, instrumental birth and caesarean section but not for preterm birth (OR 0.92, 95% CI 0.71-1.19) or neonatal death (OR 0.99; 95% CI 0.51-1.91). Conclusion RFM are associated with increased odds of stillbirth and small for gestational age, induction of labour, instrumental birth and caesarean section but not neonatal death.
