The stress of growing up in a poor and unstable household affects children as young as 9 years old on a genetic level, shortening a portion of their chromosomes that scientists say is a key indicator of aging and illness, according to a study released Monday. The researchers say their findings are the first that document this type of genetic change among minority children, and make a strong case for the importance of early-childhood intervention in vulnerable communities.
Researchers examined the DNA of a small group of 9-year-old African-American boys who had experienced chronic stress as a result of growing up in families with poor socioeconomic status. They found that the boys’ telomeres were shorter than those of boys the same age and ethnicity who came from advantaged families.
