Abstract

Socially disadvantaged individuals are at greater risk for simultaneously being exposed to adverse social and environmental conditions. Although the mechanisms underlying joint effects remain unclear, one hypothesis is that toxic social and environmental exposures have synergistic effects on inflammatory processes that underlie the development of chronic diseases, including cardiovascular disease, diabetes, depression, and certain types of cancer. In the present review, we examine how exposure to two risk factors that commonly occur with social disadvantage-early life stress and air pollution-affect health. Specifically, we identify neuroimmunologic pathways that could link early life stress, inflammation, air pollution, and poor health, and use this information to propose an integrated, multi-level model that describes how these factors may interact and cause health disparity across individuals based on social disadvantage. This model highlights the importance of interdisciplinary research considering multiple exposures across domains and the potential for synergistic, cross-domain effects on health, and may help identify factors that could potentially be targeted to reduce disease risk and improve lifespan health.

  • Systemic chronic inflammation during pregnancy and childhood can elevate the risk of non-communicable diseases across the life span.

    “SCI during pregnancy and childhood can have serious developmental consequences that include elevating the risk of non-communicable diseases over the life span7,8,26,27.”
  • Childhood conditions have a major influence on later metabolic and immune responses, which then drive SCI in adulthood.

    “childhood circumstances significantly impact metabolic and immune responses later in life, which in turn promote SCI in adulthood8,26,27,168,169”
  • Early-life psychological stress-from abuse, neglect, maltreatment, bullying or low socioeconomic conditions-can intensify neural threat responses, increase inflammatory activity, change immune competence, and produce SCI across the lifespan.

    “exposure to psychological stress early in life—for example, in the form of abuse, neglect, maltreatment, bullying or living in a low socioeconomic environment—can heighten neural responses to threat that can upregulate inflammatory activity170, alter immuno-competence and lead to SCI throughout the lifecycle27,169”
  • Early life and childhood exposure to antibiotics, vaccination, diet, smoke, and psychosocial stress seems to lead to a long-term adverse influence throughout life.

    “Early life and childhood exposure to antibiotics, vaccination, diet, smoke, and psychosocial stress seems to lead to a long-term adverse influence throughout life.”

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.
