Abstract

Behavioral scientists have increasingly included inflammatory biology as mechanisms in their investigation of psychosocial dynamics on the pathobiology of disease. However, a lack of standardization of inclusion and exclusion criteria and assessment of relevant control variables impacts the interpretation of these studies. The present paper reviews and discusses human biobehavioral factors that can affect the measurement of circulating markers of inflammation. Keywords relevant to inflammatory biology and biobehavioral factors were searched through PubMed. Age, sex, and hormonal status, socioeconomic status, ethnicity and race, body mass index, exercise, diet, caffeine, smoking, alcohol, sleep disruption, antidepressants, aspirin, and medications for cardiovascular disease are all reviewed. A tiered set of recommendations as to whether each variable should be assessed, controlled for, or used as an exclusion criteria is provided. These recommendations provide a framework for observational and intervention studies investigating linkages between psychosocial and behavioral factors and inflammation.

  • Health behaviors were assessed using validated self-report items.

    “Health behaviors were assessed using validated self-report items (O’Connor et al., 2009) including cigarette smoking status (never/former/current), alcohol use (drinks per week), and physical activity (minutes per week of moderate-to-vigorous intensity activity).”

    The Smoking recommendations say smoking is typically assessed by self-report, the Alcohol recommendations call for current consumption histories, and the Exercise section says self-reported exercise frequency and duration are commonly used. The paper does not establish that the citing study’s items were validated or specify its never/former/current, drinks-per-week, and moderate-to-vigorous-minutes-per-week measures. Page numbers were not available in our copy. (LLM, conf=0.86)

  • Behavioral and biological pathways can mediate the effects of psychological factors on inflammatory markers, such as regulation strategies.

    “As explained by O’Connor et al. (2009), behavioral and biological pathways can also mediate the effects of psychological factors on the inflammatory markers, such as regulation strategies.”

    From Strong Enough to Suffer: Emotional Suppression, Stress Exposure, and Physiological Health Among Men Across the Life Course (2026) · cites this paper as O’Connor et al., 2009

    The Introduction says behavioral factors may mediate a relationship between psychological factors and inflammation, giving sleep disturbance as a possible mediator of the depression–inflammation relationship. It does not identify regulation strategies as an example or establish the claimed biological pathways; the Summary also cautions that the direction of many reported effects cannot be determined conclusively. Page numbers are unavailable in our copy. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • The study examined alternative explanations by statistically controlling for plausible demographic and biobehavioral confounders.

    “We examined alternative explanations by statistically controlling for plausible demographic and biobehavioral confounders (29).”
  • The analyses controlled for sociodemographic factors, health behaviors, depressive symptoms, and birth control pill use based on prior work.

    “Based on prior work,12,45,46 we controlled for extraneous factors associated with inflammation.”

  • We controlled for extraneous factors that have been associated with inflammation.

    “Based on prior work (Horn et al., 2018; Lee and Way, 2019; O'Connor et al., 2009), we controlled for extraneous factors that have been associated with inflammation.”

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.
