The purpose of this study was to examine the association of ACEs, both as a cumulative score and individual forms of adversity, with epigenetic age acceleration assessed using the DNA methylation (DNAm) GrimAge and DNAm PhenoAge epigenetic clocks in middle and older\u2010aged adults. This cross\u2010sectional study analyzed baseline and first follow\u2010up data on 1445 participants aged 45\u201385\u2009years from the Canadian Longitudinal Study on Aging (CLSA) who provided blood samples for DNAm analysis. ACEs were assessed using a validated self\u2010reported questionnaire. Epigenetic age acceleration was estimated by regressing each epigenetic clock estimate on chronological age. Cumulative ACEs score was associated with higher DNAm GrimAge acceleration (\u03b2: 0.07; 95% CI: 0.02, 0.11) after adjusting for covariates. Childhood exposure to parental separation or divorce (\u03b2: 0.06; 95% CI: 0.00, 0.11) and emotional abuse (\u03b2: 0.06; 95% CI: 0.00, 0.12) were associated with higher DNAm GrimAge acceleration after adjusting for other adversities and covariates. There was no statistical association between ACEs and DNAm PhenoAge acceleration. Early life adversity may become biologically embedded and lead to premature biological aging, in relation to DNAm GrimAge, which estimates risk of mortality. Strategies that increase awareness of ACEs and promote healthy child development are needed to prevent ACEs.<\/jats:p>","DOI":"10.1111\/acel.13779","type":"journal-article","created":{"date-parts":[[2023,1,18]],"date-time":"2023-01-18T07:01:16Z","timestamp":1674025276000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":49,"title":["The association between adverse childhood experiences and epigenetic age acceleration in the Canadian longitudinal study on aging (<scp>CLSA<\/scp>)"],"prefix":"10.1111","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3190-8866","authenticated-orcid":false,"given":"Divya","family":"Joshi","sequence":"first","affiliation":[{"name":"Department of Health Research Methods, Evidence, and Impact McMaster University  Hamilton Ontario Canada"},{"name":"Labarge Centre for Mobility in Aging McMaster University  Hamilton Ontario Canada"},{"name":"McMaster Institute for Research on Aging McMaster University  Hamilton Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Gonzalez","sequence":"additional","affiliation":[{"name":"Labarge Centre for Mobility in Aging McMaster University  Hamilton Ontario Canada"},{"name":"McMaster Institute for Research on Aging McMaster University  Hamilton Ontario Canada"},{"name":"Department of Psychiatry and Behavioral Neurosciences McMaster University  Hamilton Ontario Canada"},{"name":"Offord Centre for Child Studies  Hamilton Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Lin","sequence":"additional","affiliation":[{"name":"Centre for Molecular Medicine and Therapeutics BC Children's Hospital Research Institute  Vancouver British Columbia Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Parminder","family":"Raina","sequence":"additional","affiliation":[{"name":"Department of Health Research Methods, Evidence, and Impact McMaster University  Hamilton Ontario Canada"},{"name":"Labarge Centre for Mobility in Aging McMaster University  Hamilton Ontario Canada"},{"name":"McMaster Institute for Research on Aging McMaster University  Hamilton Ontario Canada"},{"name":"Department of Psychiatry and Behavioral Neurosciences McMaster University  Hamilton Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,1,17]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/pubmed\/fdu065"},{"issue":"3","key":"e_1_2_10_3_1","first-page":"163","article-title":"Beta 2\u2010microglobulin: Its significance and clinical usefulness","volume":"20","author":"Bethea M.","year":"1990","journal-title":"Annals of Clinical and Laboratory Science"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/jcpp.12495"},{"key":"e_1_2_10_5_1","unstructured":"David L.
