Pregnancy hyperemesis associated with increased risk of autism in children, according to a new study

According to a study by the American Journal of Perinatology, pregnant women with hyperemia during pregnancy may have a 53% higher risk of having a child with an acoustic spectrum disorder.

The study, funded by the American institute Kaiser Permanente, is important, according to the principal author, Darius Getaun, because through this association we can better diagnose children at risk of autism and conduct early interventions.

Hyperthermia during pregnancy is a severe form of morning sickness that occurs in about 5% of pregnancies. Usually, women suffering from it cannot contain any food or liquid, which can cause severe dehydration, as well as insufficient or insufficient nutrition during the same pregnancy.

Researchers have found this link by analyzing the health records of nearly 500,000 pregnant women and their babies born between 1991 and 2014. They focused in particular on women suffering from hyperemia during pregnancy and compared their children’s pathologies with those that did not cause such severe nausea in mothers.

Researchers noted that children of mothers with hyperemia during pregnancy were at greater risk of autism when the same hyperemia was diagnosed in the first or second trimester of pregnancy, but not when it was diagnosed in the third trimester.

Researchers also noted that the association is stronger in female daughters than in male sons and stronger in whites and Hispanics than in blacks. The same researchers, as indicated in the press release (see first link below), exclude links between drugs used to control hyperemia during pregnancy and the same risk of autism.

This is an observational study that cannot identify the immediate cause, and therefore other studies should be conducted to examine the causes of this association. There may be other explanations, even if the researchers themselves suspect that women who suffer from hyperemia during pregnancy are more likely to suffer from poor nutrition, which in turn may harm the neurological development of children.
