Abstract

Maternal prenatal psychosocial stress is associated with altered child emotional and behavioral development. One potential underlying mechanism is that prenatal psychosocial stress affects child outcomes via the mother’s, and in turn the child’s, intestinal microbiota. This study investigates the first step of this mechanism: the relation between psychosocial stress and fecal microbiota in pregnant mothers. Mothers (N = 70) provided a late pregnancy stool sample and filled in questionnaires on general and pregnancy-specific stress and anxiety. Bacterial DNA was extracted and analysed by Illumina HiSeq sequencing of PCR-amplified 16 S ribosomal RNA gene fragments. Associations between maternal general anxiety and microbial composition were found. No associations between the other measured psychosocial stress variables and the relative abundance of microbial groups were detected. This study shows associations between maternal pregnancy general anxiety and microbial composition, providing first evidence of a mechanism through which psychological symptoms in pregnancy may affect the offspring.

  • Maternal stress during pregnancy is associated with a distinct fecal microbiota profile.

    “In addition, maternal stress during pregnancy display a distinct fecal microbiota profile (Hantsoo et al., 2019;Hechler et al., 2019), that has generational consequences.”

    From The Microbiota-Gut-Brain Axis (2019) · cites this paper as Hechler et al., 2019

    The Discussion reports a distinct genus-level fecal microbiota composition associated with general anxiety in late pregnancy. It also says the study found no significant associations for general stress or pregnancy-specific stress and anxiety, so the broader claim about maternal stress is overstated. The paper describes consequences for offspring as a potential mechanism, not an outcome it tested. (LLM, conf=0.87)

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.
