The Sibona Abantwana study is a sub-study to the Siyakubona Project , which is investigating the impact of implementing routine point-of-care ultrasound at primary health care clinics. Selected Siyakubona facilities – including those where the Sibona Abantwana study are being conducted – are also implementing routine third-trimester Doppler screening with the Umbiflow™ device. Umbiflow™ is used to see whether the placenta is functioning well.
Placental insufficiency – a condition where the placenta does not deliver enough nutrients and oxygen to the growing foetus – is seen in more than 10% of otherwise healthy pregnant women in Tshwane. This condition carries a high risk of stillbirth and of foetal growth restriction. Babies born after experiencing foetal growth restriction are smaller than they should be, and their brain development may be negatively impacted.
We do not know why placental insufficiency is so common in women who have no risk factors for pregnancy complications – this is one of the questions the Sibona Abantwana study is trying to answer, since we can only start developing treatments once we understand the underlying causes. We are also looking at the outcomes in infants up to one year, in terms of both growth and neurodevelopment.

The study aims to recruit 225 pregnant women – 75 pregnant women with preeclampsia (a severe form of placental disease with hypertension, which has been more widely studied), 75 pregnant women with placental insufficiency but an otherwise healthy pregnancy, and 75 pregnant women with a healthy pregnancy and normal placental function. By comparing these three groups, we hope to see if placental insufficiency has some underlying factors in common with preeclampsia. All these infants will be followed up until they are one year old. Additionally, we will recruit 75 more preterm infants from Kalafong Hospital who had a Doppler test of placental function done in pregnancy. This will allow us to see whether babies born preterm do better, worse or similarly to babies born at term in the first year of life.
Sibona Abantwana is a multidisciplinary study, bringing together expert collaborators from disciplines as diverse as obstetrics, paediatrics, nutrition, immunology, haematology, medical microbiology, and pathology.
