Study: Calcium Might be a Cause of Preterm Births

For the most part, experts do not really know the exact cause of preterm births in a healthy woman, an event that can kill the baby or cause lifelong health problems. It also drives up hospital costs. Preterm birth is delivery before 37 weeks of gestation. Often infection is the cause, but not always. Researchers at the Nationwide Children’s Hospital in Columbus, Ohio, studying more than 100 pregnant women, have discovered another possible culprit: calcium buildup in the womb. It’s the kind of buildup that clogs arteries and causes kidney stones in older people. That’s because calciprotein particles in the blood and can sometimes be deposited in soft tissue instead of bones.


Researchers found higher levels of calcium in the amniotic sac from mothers who gave preterm birth than those who gave full-term births. Blood tests for the mother doesn’t uncover signs of this problem.


In a study published yesterday in Science Translational Medicine, researchers suggest that providers attempt therapeutic or dietary methods to maintain the balance between the formation of endogenous hydroxyapatite and fetuin reserve in pregnant in pregnant women.
