Father Time’s Racial Bias

Tom Jacobs highlights new (but not the first) research showing that African-Americans “age” faster than those of other races:

“On average, the biological age for blacks was 53.16 years,” compared to 49.84 years for whites, the researchers report. After controlling for socioeconomic status and health behaviors (they note that obesity rates are higher for blacks than whites, and excess weight can “contribute to progressive breakdowns in biological tissues and systems”), this gap shrank somewhat, but was still pronounced: 52.72 years for blacks, compared to 49.89 years for whites.

Previous researchers have pointed to the corrosive influence of racism as a possible explanation for the poorer health of blacks in America. A small study released in January found blacks who had experienced racism and come to accept (even unconsciously) the concept of racial inferiority had shorter leukocyte telomeres—a different biomarker of aging.

Levine and Crimmins did not attempt to measure negative health effects of racism, but their results are consistent with the theory.
