NEW YORK (Reuters Health) - Pregnant women can reduce their risk of miscarriage if they fall on their sides, not on their backs, a recent British study showed.
The study was conducted by researchers at the University of Huddersfield and published in the journal EclinicalMedicine.
The team continued to have 851 mothers who had undergone abortions and 225 women who had continued to conceive until they gave birth.
The researchers found that pregnant women who slept on their backs from the 28 weeks of gestation increased their risk of miscarriage and loss of pregnancy by 2.6 times as much as those who slept on their sides.
The National Health Services (NHS) has incorporated the findings of the study into recommendations to halve child deaths in the UK.
The head of the research team, Dr. Tomasina Stacey, said that lying on the back presses the main veins that send blood back to the mother's heart, which reduces blood flow to the uterus.
And on the best position for the sleep of pregnant women, she said that sleep on the left side is appropriate for the fetus to reduce the pressure on the vein in this situation, which reduces swelling of the legs and promotes the efficiency of circulation.
The American Pregnancy Society called on expectant mothers to avoid sleeping on their backs, because this position can reduce the efficiency of blood circulation in the heart of the mother and child.
