Educational Mobility, Pace of Aging, and Lifespan Among Participants in the Framingham Heart Study
GH Graaf et al, JAMA Network Open, March 1, 2024

From the abstract: " Is upward educational mobility associated with a slower pace of biological aging and increased longevity? In this cohort study of 3101 participants representing 2 generations of the Framingham Heart Study, upward educational mobility was associated with a slower pace of aging (as measured with whole-blood DNA-methylation data) and lower risk of death. Slower pace of aging accounted for approximately half of the association between educational mobility and mortality. These results suggest that interventions to promote educational attainment may slow the pace of biological aging and promote longevity. "

Validation of biomarkers of aging.
Mahdi Moqri et al. Nat Med 2024 2

From the abstract: "The search for biomarkers that quantify biological aging (particularly ‘omic’-based biomarkers) has intensified in recent years. Such biomarkers could predict aging-related outcomes and could serve as surrogate endpoints for the evaluation of interventions promoting healthy aging and longevity. However, no consensus exists on how biomarkers of aging should be validated before their translation to the clinic. Here, we review current efforts to evaluate the predictive validity of omic biomarkers of aging in population studies, discuss challenges in comparability and generalizability. "

Mendelian randomization evidence for the causal effects of socio-economic inequality on human longevity among Europeans.
Chao-Jie Ye et al. Nat Hum Behav 2023 6

Here we performed two-sample Mendelian randomization analyses applying genetic instruments of education, income and occupation (n?=?248,847 to 1,131,881) to estimate their causal effects and consequences on parental lifespan and self-longevity (n?=?28,967 to 1,012,240) from the largest available genome-wide association studies in populations of European ancestry. Each 4.20 years of additional educational attainment were causally associated with a 3.23-year-longer parental lifespan independently of income and occupation and were causally associated with 30–59% higher odds of self-longevity.
