Latinos age slower than other ethnicities
UCLA scientists noticed that, after accounting for differences in cell composition, the blood of Latinos aged more slowly than other groups.
A UCLA study is the first to show that Latinos age at a slower rate than other ethnic groups.
“Latinos live longer than Caucasians, despite experiencing higher rates of diabetes and other diseases. Scientists refer to this as the ‘Hispanic paradox,’” said lead author Steve Horvath, a professor of human genetics at the David Geffen School of Medicine at UCLA. “Our study helps explain this by demonstrating that Latinos age more slowly at the molecular level.”
When the scientists examined the DNA from blood — which reveals the health of a person’s immune system — the scientists noticed that the blood of Latinos aged more slowly than other groups.
“We suspect that Latinos’ slower aging rate helps neutralize their higher health risks, particularly those related to obesity and inflammation,” said Horvath. “Our findings strongly suggest that genetic or environmental factors linked to ethnicity may influence how quickly a person ages and how long they live.”
