We classified individuals with extreme values as having epigenetic age acceleration (EAA) or epigenetic age deceleration. A subset of participants with longitudinal methylation profiling was categorized as accelerated versus nonaccelerated. Using principal components analysis, we created phenoclusters using 122 phenotypic variables and compared individuals with EAA versus epigenetic age deceleration, and at one year of follow-up, using logistic regression models adjusted for sex (false discovery rate [\n              <jats:italic>Q<\/jats:italic>\n              ] &lt;0.10); in secondary exploratory analyses, we tested individual clinical variables.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results:<\/jats:title>\n            <jats:p>\n              The EAA (n=188) and epigenetic age deceleration (n=195) groups were identified as having EAA estimates \u22655 years or \u2264\u22125 years, respectively. In primary analyses, individuals with EAA had higher values for phenoclusters summarizing lung function and lipids, and lower values for a phenocluster representing physical function. In secondary analyses of individual variables, neutrophils, body mass index, and waist circumference were significantly higher in individuals with EAA (\n              <jats:italic>Q<\/jats:italic>\n              &lt;0.10).
