Abstract

In attempts to understand the social determinants of health, strong associations have been found between measures of loneliness, physiological stress processes, and physical and mental health outcomes. Feelings of loneliness are hypothesized to have implications for physiological stress processes, including activity of the hypothalamic-pituitary-adrenal (HPA) axis. In a community sample of young adults, multilevel modeling was used to examine whether trait and state feelings of loneliness were related to changes in levels of the stress-sensitive hormone cortisol, and whether the associations between loneliness and cortisol were mediated or moderated by the presence of concurrent depression or high levels of chronic life stress. Results indicated that trait loneliness was associated with a flattening of the diurnal cortisol rhythm. In addition, both daily and momentary state variations in loneliness were related to cortisol. Prior day feelings of loneliness were associated with an increased cortisol awakening response the next morning and momentary experiences of loneliness during the day were associated with momentary increases in cortisol among youth who also had high chronic interpersonal stress. Results were significant after covarying current depression, both chronic and momentary reports of stress, and medical and lifestyle covariates. This study expanded on prior work by investigating and revealing three different time courses of association between loneliness and HPA axis activity in young adults: trait, daily and momentary.

  • Loneliness affects youth's diurnal cortisol, potentially causing chronic increases in cortisol in young adulthood, leading to higher risks of depression, anxiety, inflammation, and other adverse health outcomes.

    “Loneliness affects youth’s diurnal cortisol, a key stress hormone [83, 84], potentially causing chronic increases in cortisol in young adulthood, leading to higher risks of depression, anxiety, inflammation, and other adverse health outcomes [85–87].”
  • Perceived support and loneliness have been linked to differences in basal cortisol, which affects immune, metabolic, and cardiovascular outcomes relevant to ADRD risk in older adults.

    “For example, perceived social support and loneliness have been associated with variation in basal cortisol, which influences immune system, metabolic, and cardiovascular outcomes implicated in ADRD risk in older adults.39,40”
  • High self-reported loneliness in humans is associated with elevated daily cortisol output and a flatter diurnal cortisol rhythm, suggesting poor HPA regulation.

    “high self-reported loneliness in humans has been associated with elevated daily cortisol output62–66 and a flattening of diurnal cortisol rhythm65, suggesting poor regulation of the HPA axis67.”

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.
