Abstract

Adverse experiences in early life have the ability to "get under the skin" and affect future health. This study examined the relative influence of adversities during childhood and adulthood in accounting for individual differences in pro-inflammatory gene expression in late life. Using a pilot-sample from the Health and Retirement Study (N = 114) aged from 51 to 95, OLS regression models were run to determine the association between a composite score from three proinflammatory gene expression levels (PTGS2, ILIB, and IL8) and 1) childhood trauma, 2) childhood SES, 3) childhood health, 4) adult traumas, and 5) low SES in adulthood. Our results showed that only childhood trauma was found to be associated with increased inflammatory transcription in late life. Furthermore, examination of interaction effects showed that childhood trauma exacerbated the influence of low SES in adulthood on elevated levels of inflammatory gene expression-signifying that having low SES in adulthood was most damaging for persons who had experienced traumatic events during their childhood. Overall our study suggests that traumas experienced during childhood may alter the stress response, leading to more sensitive reactivity throughout the lifespan. As a result, individuals who experienced greater adversity in early life may be at higher risk of late life health outcomes, particularly if adulthood adversity related to SES persists.

  • In the Health and Retirement Study, childhood adversity had a significant effect on proinflammatory gene expression.

    “When broken down by life period, childhood adversity had a significant effect on proinflammatory gene expression (Levine et al., 2015), as well as telomere length (Puterman et al., 2016), both potential mechanisms of disease development.”

    From More than a feeling: A unified view of stress measurement for population science (2018) · cites this paper as Levine et al., 2015

    The Results section reports a significant association between childhood trauma and proinflammatory gene expression in a Health and Retirement Study pilot sample. It found no significant association for childhood socioeconomic status or health, so the broader term “childhood adversity” overstates the finding; the observational analysis also establishes an association, not a causal effect.

  • Acute or chronic stress can lead to an increased production of pro-inflammatory cytokines.

    “A risk factor like acute or chronic stress could, for example, lead to an increased production of pro-inflammatory cytokines (115, 138–140)”

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.
