Discovered genes that make women angry with their babies

American scientists have identified a gene that causes some uncontrolled mothers to beat or scold their children.

Scientists at New York University have found a dramatic increase in the proportion of parents with children during the Great Depression in the US between 2007 and 2009, especially in women with a genetic mutation. mood control .

Dr. Dohoon Lee and colleagues conducted research with 5,000 children born in 20 major US cities during the period from 1998 and 2000. The mothers of these children were asked questions. right after birth as well as when their baby is 1 year, 3 years old, 5 years old and 9 years old.

Data on hot parents with children are collected when their children are 3 years old, 5 years old and 9 years old. Scientists then took DNA samples with saliva from more than 2,600 mothers and children at the end of the study.

Scientists divided the level of parental control over children into different levels such as scolding and intimidation, as well as battering or butt slapping. The team also analyzed the economic situation in cities where mothers whose children live based on monthly unemployment and consumption figures.

The results show that the maternal ministry rises with children increasing in cities where the rate of occupation and consumption decreases. Scientists believe that the anxiety of losing jobs due to economic recession makes parents easily angry with their children.

The team also found that mothers with damaged DRD2 genes were more likely to get angry with their children, especially in the economic conditions of their depressed areas and reduced consumer index. Only about half of the mothers surveyed had DRD2 gene, controlled action and chemical control of mood in the brain.
