An analysis of the mystery of twin health

1. Premature delivery is good for twins. Twins are usually born earlier, which researchers think is a good thing, because twins are at greater risk of problems during pregnancy. Jody Dodd, a professor at Robinson Institute and Women's and Children's Hospital of the University of Adelaide in Australia, said: Premature delivery can reduce the time twins spend with their mothers and reduce the risk of various diseases.

2. The possibility of a mother suffering from gestational diabetes will increase by 2-3 times. According to the official report of the American Pregnancy Association, two placentas will increase the insulin resistance of pregnant women, and the increase of placental size and placental hormone content will also promote gestational diabetes.

3. The mother of twins lives long. Researchers at the University of Utah surveyed the birth records of more than 59,000 women and found that twin mothers live longer than single mothers.

4. Identical twins are more likely to suffer from Down syndrome. The risk of Down's syndrome in fraternal twins will not increase, and the risk of Down's syndrome in fraternal twins is the same as that in singletons, both of which are 1/800. For identical twins, although the probability of Down syndrome in fertilized eggs is 1/800, the probability of Down syndrome in one of them is 100% because it is split from an embryo.
