Abstract

OBJECTIVE: DNA methylation has been proposed as an epigenetic mechanism by which early-life experiences become "embedded" in the genome and alter transcriptional processes to compromise health. The authors sought to investigate whether early-life victimization stress is associated with genome-wide DNA methylation. METHOD: The authors tested the hypothesis that victimization is associated with DNA methylation in the Environmental Risk (E-Risk) Longitudinal Study, a nationally representative 1994-1995 birth cohort of 2,232 twins born in England and Wales and assessed at ages 5, 7, 10, 12, and 18 years. Multiple forms of victimization were ascertained in childhood and adolescence (including physical, sexual, and emotional abuse; neglect; exposure to intimate-partner violence; bullying; cyber-victimization; and crime). RESULTS: Epigenome-wide analyses of polyvictimization across childhood and adolescence revealed few significant associations with DNA methylation in peripheral blood at age 18, but these analyses were confounded by tobacco smoking and/or did not survive co-twin control tests. Secondary analyses of specific forms of victimization revealed sparse associations with DNA methylation that did not replicate across different operationalizations of the same putative victimization experience. Hypothesis-driven analyses of six candidate genes in the stress response (NR3C1, FKBP5, BDNF, AVP, CRHR1, SLC6A4) did not reveal predicted associations with DNA methylation in probes annotated to these genes. CONCLUSIONS: Findings from this epidemiological analysis of the epigenetic effects of early-life stress do not support the hypothesis of robust changes in DNA methylation in victimized young people. We need to come to terms with the possibility that epigenetic epidemiology is not yet well matched to experimental, nonhuman models in uncovering the biological embedding of stress.

  • Evidence of associations between epigenetic/epigenomic alterations and differential health outcomes induced by childhood trauma is limited.

    “Even though numerous studies have been done, evidence of associations between epigenetic/epigenomic alterations and differential health outcomes induced by childhood trauma are limited (226).”

    From Epigenetic Modifications in Stress Response Genes Associated With Childhood Trauma (2019) · cites this paper as [226]

    The Discussion (page unavailable) reports limited, small, and poorly replicated associations between childhood victimization and DNA methylation in blood. It describes epigenetic mediation of poor health as a hypothesis, but does not establish whether epigenetic alterations are associated with differential health outcomes following trauma. The claim therefore extends beyond the association this paper tested. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Well-powered studies have also reported negative results for associations between childhood maltreatment and DNA methylation differences.

    “However, well-powered studies have also reported negative results. 62”

    From Epigenetics and depression (2019) · cites this paper as [62]

  • A study examining the impact of childhood adversity on the epigenome in a general population found tobacco consumption was an important confounder when examining the signature of childhood adversity.

    “A similar study examining the impact of CA on the epigenome in a general population found that tobacco consumption was an important confounding when examining the signature of CA (Marzi et al., 2018).”
  • The modal clinical presentation of people with personality disorders is a complaint of depression and significant proportions of people with depression have a comorbid personality disorder.

    “Indeed, the modal clinical presentation of people with personality disorders is a complaint of depression 271,272 and significant proportions of people with depression have a comorbid personality disorder. 273”

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.
