Introduction. We aimed to determine whether the clinical characteristics of women in uncomplicated pregnancies presenting with decreased foetal movements (DFMs) would help target subgroups of women at the highest risk. Furthermore, we also aimed whether DFMs in complicated pregnancies identified the additional needs for intensified management. Methods. Singleton third trimester pregnancies (n = 2374) presenting with DFMs from June 2004 through October 2005 were prospectively registered in 14 delivery units in Norway. Among pregnancies that were uncomplicated until registration for DFMs, cases with good outcomes (birth weight between 10th and 90th percentile, term delivery and live-born child) were compared with cases with adverse outcomes. Results. In uncomplicated pregnancies, maternal overweight, advanced age and smoking identified subgroups of cases at increased risk of foetal growth restriction and stillbirth. DFMs of longer duration, in particular the perceived absence of movements, identified cases at increased risk of stillbirth, irrespective of other maternal characteristics. When women with complicated pregnancies reported DFMs, additional indications for follow-up were found in 1/3 of cases. Conclusions. Maternal overweight, advanced age, smoking and the duration of DFMs are the characteristics that help in identifying pregnancies that should be targeted for intensified management. Time matters and knowledge-based information are needed to improve foetal health.
