Morning Sickness Can Increase Autism Risk in Children: Study

Awareness of an association may create the opportunity for earlier diagnosis and intervention in children at risk of autism

Children whose mothers had hyperemesis gravidarum, a severe form of morning sickness, during pregnancy were 53 per cent more likely to be diagnosed with an autism spectrum disorder, a study said.

Hyperemesis gravidarum occurs in less than five per cent of pregnancies. Affected women experience intense nausea and are unable to keep down food and fluids.

This could lead to dangerous dehydration and inadequate nutrition during pregnancy.

“This study is important because it suggests that children born to women with hyperemesis may be at an increased risk of autism,” said the study’s lead author Darios Getahun, Kaiser Permanente Southern California Department of Research and Evaluation.

“Awareness of this association may create the opportunity for earlier diagnosis and intervention in children at risk of autism,” Getahun said,

For the study published in the American Journal of Perinatology, researchers reviewed the electronic health records of nearly 500,000 pregnant women and their Children born between 1991-2014 in Southern California.

They compared children whose mothers had a diagnosis of hyperemesis gravidarum during pregnancy to those whose mothers did not.

The researchers found that exposure to hyperemesis gravidarum was associated with increased risk of autism when the disease was diagnosed during the first and second trimesters of pregnancy, but not when it was diagnosed only in the third trimester.

Exposure to the disease was associated with the risk of autism regardless of the severity of the mother’s hyperemesis gravidarum, the study said.

The results are consistent with the hypothesis that women experiencing hyperemesis gravidarum have a poor nutritional intake, which might, in turn lead to potential long-term neurodevelopment impairment in their children. (IANS)

Researchers at the University of Bristol have found evidence of an association between generalised Anxiety disorder at age 18 and harmful drinking three years later.

The study, published in the journal Drug and Alcohol Dependence strengthens the evidence for a relationship between anxiety and later alcohol use as the researchers accounted for other factors such as adolescent smoking and cannabis use, and parental anxiety and alcohol use.

“Helping adolescents to develop positive strategies for coping with anxiety, instead of drinking alcohol, may reduce the risk of future harmful drinking. However, we cannot determine if the relationship is causal, because we used an observational study design,” said Maddy Dyer.

Using questionnaire and clinical interview data from more than 2,000 participants, researchers found generalised anxiety disorder at age 18 was linked to frequent drinking, frequent bingeing, hazardous drinking, and harmful drinking at age 18.

Generalised anxiety disorder continued to be associated with harmful drinking at age 21.

Drinking to cope was also strongly associated with more harmful drinking, but it did not appear to influence associations between anxiety and alcohol use.

Harmful drinking was measured using a special test developed by the World Health Association.

On average, adolescents with anxiety drank at more harmful levels regardless of whether they tended to drink alcohol for coping reasons or not.

“Our own research has shown that links between mental health problems, such as anxiety disorders, and alcohol are common and complex,” said Mark Leyshon, Senior Policy and Research Manager at Alcohol Change UK.

For example, anxiety can be both a result of stopping drinking and a risk factor in beginning to drink too much, as this new study suggests.

“We need more research to help us better understand the connections between alcohol and mental health, as well as high-quality, accessible, integrated support for substance misuse and mental health issues,” Leyshon added. (IANS)
