A New Zealand-led international study provides evidence that women can more than halve their risk of stillbirth by going to sleep on either side during the last three months of pregnancy, reports The New Zealand Herald.

This mega study (known as individual participant data meta-analysis) has also confirmed the risk of stillbirth associated with sleeping on the back applies to all pregnant women in the last trimester of pregnancy.

The main finding in the mega study, which included information from 851 bereaved mothers and 2,257 women with ongoing pregnancies, was that going to sleep lying on the back (supine) from 28 weeks of pregnancy increased the risk of stillbirth 2.6 times.
