Abstract

Importance: This study was designed to determine whether a preventive intervention focused on enhancing supportive parenting could ameliorate the association between exposure to poverty and brain development in low socioeconomic status African American individuals from the rural South. Objective: To determine whether participation in an efficacious prevention program designed to enhance supportive parenting for rural African American children will ameliorate the association between living in poverty and reduced hippocampal and amygdalar volumes in adulthood. Design, Setting, and Participants: In the rural southeastern United States, African American parents and their 11-year-old children were assigned randomly to the Strong African American Families randomized prevention trial or to a control condition. Parents provided data used to calculate income-to-needs ratios when children were aged 11 to 13 years and 16 to 18 years. When the participants were aged 25 years, hippocampal and amygdalar volumes were measured using magnetic resonance imaging. Exposures: Household poverty was measured by income-to-needs ratios. Main Outcomes and Measures: Young adults' whole hippocampal, dentate gyrus, and CA3 hippocampal subfields as well as amygdalar volumes were assessed using magnetic resonance imaging. Results: Of the 667 participants in the Strong African American Families randomized prevention trial, 119 right-handed African American individuals aged 25 years living in rural areas were recruited. Years lived in poverty across ages 11 to 18 years forecasted diminished left dentate gyrus (simple slope, -14.20; standard error, 5.22; P = .008) and CA3 (simple slope, -6.42; standard error, 2.42; P = .009) hippocampal subfields and left amygdalar (simple slope, -34.62; standard error, 12.74; P = .008) volumes among young adults in the control condition (mean [SD] time, 2.04 [1.88] years) but not among those who participated in the Strong African American Families program (mean [SD] time, 2.61 [1.77] years). Conclusions and Relevance: In this study, we described how participation in a randomized clinical trial designed to enhance supportive parenting ameliorated the association of years lived in poverty with left dentate gyrus and CA3 hippocampal subfields and left amygdalar volumes. These findings are consistent with a possible role for supportive parenting and suggest a strategy for narrowing social disparities.

  • Caregiving-focused interventions improved ELA-associated chronic inflammation, telomere shortening, and gray matter volumetric changes in longitudinal research.

    “Some parameters improved by caregiving-focused interventions in longitudinal research include ELA-associated chronic inflammation [98], telomere shortening (accelerated genetic aging) [99], and gray matter volumetric changes [100].”

    From Biological embedding of childhood adversity: from physiological mechanisms to clinical implications (2017) · cites this paper as [100]

    Citation [100] is attached to gray matter volumetric changes, not the inflammation or telomere claims, which have separate citations. The Abstract reports that a parenting-focused intervention ameliorated the association between years lived in poverty and adult hippocampal and amygdalar volumes. The Discussion’s Limitations section says pretrial volumes were not measured, so the study could not determine whether volumes changed differently over time between groups. (LLM, conf=0.88)

  • Caregiving-focused interventions may mitigate the physiological effects of ELA.

    “Considerable evidence suggests that caregiving-focused interventions, for instance, may mitigate the physiological effects of ELA.”
  • Evidence-based prevention can interrupt the adverse consequences of social determinants on addiction.

    “and how evidence-based prevention can interrupt those adverse consequences [79,80].”

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.
