Blame your parents for all your problems? Science supports that.
New report written by researchers at Lomo Linda University suggests that being a parent at a distance and without support harms the genetic health of their children, potentially leading to illness and premature death at age adult.
"The way a person is raised seems to tell a story related to their genetics," says Dr. Raymond Knutsen, lead author of the study, professor of public health at Lomo Linda University.
Telomeres are the protective tips at the ends of the DNA strands that protect our chromosomes from damage and decay. When our DNA is not properly protected, our cells age faster and we become more vulnerable to disease.
Of the 200 subjects followed for this study, which will appear in the July edition of Biological Psychology, researchers found that those who reported growing up with a "cold" mother had telomeres that averaged 25% less than those with a "hot" person. the mothers.
"As stress at the beginning of life increases, telomeres get shorter and the risk of contracting a series of diseases increases, as well as premature death," says Knutsen.
The researchers also examined how the level of education and body mass index (BMI) could play a role in a child's DNA response to a cold parenthood .
"The link with parenting style was most important in less educated people," the paper says, "and in those who have retained excess weight / obesity or gained weight during follow-up."
This suggests that "both higher education and normal BMI may offer some resistance to parental violence and cell aging."
