Morning sickness usually attack a young pregnant woman. One study found no relationship between morning sickness and child that is born. Researchers at Sick Kids Hospital, said that morning sickness can make children more intelligent.
A new study appearing in The Journal of Pediatrics shows that feelings of nausea enhance neural long-term development of child. This study is the first time that assess the direct effects of morning sickness with neurological development of children.
Past studies have shown that there are benefits from morning sickness, but the long-term effects for children have never been studied before.
“Our findings show the relationship between NVP and increased nerve growth in the offspring,” said Dr. Irena Nulman, lead author of the study as reported by DigitalJournal.
“NVP is a physiological phenomenon broad and confusing that have not been adequately studied,” added Nulman, director of the Motherisk Program Association Program, SickKids Associate Scientist.
Study participants were recruited using a database Motherisk NVP hotline. The researchers used 121 women who are connected in the hotline since 1998 until 2003. These participants were divided into three groups of mother and child pairs. That is women who suffer morning sickness and treated with diclectin (drugs used to treat nausea and vomiting during pregnancy), a group of people who experience morning sickness and did not take diclectin, and those who do not experience morning sickness.
Then, the children who are aged 3-7 years given the age standardized tests to measure their intelligence and behavior. While outside factors examined included the mother’s IQ, the number of cigarettes smoked per day, alcohol consumption, and socioeconomic status.
As a result, this study shows that all the children in the three groups had normal average for neurodevelopmental outcome. The surprise was the children whose mothers had morning sickness indicate a higher value on the performance IQ, verbal fluency, phonological processing, and numerical memory. Use of diclectin not make a difference in children’s intelligence. The severity of morning sickness does make a difference along with the mother’s IQ.
“The results of this study emphasize the need for further scientific investigation to the physiological basis of NVP,” said Dr. Gideon Koren, Motherisk Program Director, Senior Researcher at SickKids and professor of Paediatrics, Pharmacology, Pharmacy and Medical Genetics at the University of Toronto
