Abstract

Morbidity and mortality are greater among socially disadvantaged racial/ethnic groups and those of lower socioeconomic status (SES). Greater chronic stress exposure in disadvantaged groups may contribute to this by accelerating cellular aging, indexed by shorter age-adjusted telomere length. While studies consistently relate shorter leukocyte telomere length (LTL) to stress, the few studies, mostly from the UK, examining associations of LTL with SES have been mixed. The current study examined associations between educational attainment and LTL among 2599 high-functioning black and white adults age 70-79 from the Health, Aging and Body Composition Study. Multiple regression analyses tested associations of race/ethnicity, educational attainment and income with LTL, adjusting for potential confounders. Those with only a high school education had significantly shorter mean LTL (4806 basepairs) than those with post-high school education (4926 basepairs; B=125, SE=47.6, p=.009). A significant interaction of race and education (B=207.8, SE=98.7, p=.035) revealed more beneficial effects of post-high school education for blacks than for whites. Smokers had shorter LTL than non-smokers, but the association of education and LTL remained significant when smoking was covaried (B=119.7, SE=47.6, p=.012). While higher income was associated with longer LTL, the effect was not significant (p>.10). This study provides the first demonstration of an association between educational attainment and LTL in a US population where higher education appears to have a protective effect against telomere shortening, particularly in blacks.

  • Many subject-level variables, such as age, sex, genetic polymorphisms, resiliency, education, history of early life adversities, parental responsiveness, socioeconomic status, health behaviors, diet, and latent or active viral infections, may affect LTL independent of the disease process being studied.

    “Further, many subject-level variables, such as age, sex, genetic polymorphisms, “resiliency,” education, history of early life adversities, parental responsiveness, socioeconomic status, health behaviors, diet, and latent or active viral infections (e.g., cytomegalovirus or herpes virus) may affect LTL, independent of the disease process being studied (Adler et al., 2013; Asok et al., 2013;”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
