Employment trajectories from ages 18–50 and epigenetic age acceleration by race and ethnicity
In a US survey sample, Black and Hispanic adults more often entered the workforce late; employment trajectory was largely unrelated to epigenetic age acceleration, yet racial differences in several clocks persisted within similar work histories. [1]
Automatic summary · not editorially reviewed
The key findings
Black and Hispanic adults had more than twice the odds of a late workforce entry trajectory than White adults, with differences concentrated in delayed entry. [1]
Across five epigenetic clocks (N = 1861), employment trajectory was largely unrelated to epigenetic age acceleration and did not moderate racial and ethnic differences in it. [1]
Black adults showed faster DunedinPACE and GrimAge acceleration than White adults within trajectories, but differed in the opposite direction on the Hannum clock. [1]

Work histories ages 18–50 in a US survey sample
The study used the 2016 Health and Retirement Study with the linked Life History Mail Survey and Venous Blood Study. Employment histories were built from ages 18 to 50, and sequence and cluster analysis identified four trajectories. Multinomial logistic regression showed Black and Hispanic adults had more than twice the odds of a "Late Workforce Entry" trajectory than White adults, with differences concentrated in delayed entry rather than mid-career disruption or non-employment.

Clocks largely unrelated to trajectory in weighted models
In survey-weighted ordinary least squares models across five epigenetic clocks (N = 1861), employment trajectory was largely unrelated to epigenetic age acceleration and did not moderate racial and ethnic differences in it. The authors describe this as partial alignment with the weathering hypothesis, which they used as a guiding framework.

Racial differences within similar work histories
Racial differences persisted within trajectories: Black adults showed faster DunedinPACE and GrimAge acceleration than White adults, with DunedinPACE differences within stable full-time work and both differences within long-term non-employment, while differing in the opposite direction on the age-predictive Hannum clock. The authors suggest the biological consequences of employment may depend not only on long-term work patterns but also on unequal conditions and experiences within them.

How to interpret this
Abstract only; the full text was not reviewed. This is an observational analysis of survey data, so associations are not causal, and the abstract does not report follow-up duration or clock-specific effect sizes.
Based on the study abstract; the full paper, tables and supplementary data were not reviewed.
