Chronic psychosocial stress has been shown to dysregulate hypothalamic\u2013pituitary\u2013adrenal axis and sympathetic nervous system activity, promoting low-grade systemic inflammation and altering immune signaling within the tumor microenvironment. However, few studies have examined how stress-related psychosocial factors, such as loneliness, contribute to inflammatory processes in African American breast cancer survivors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>To examine the association between loneliness and other social, socioeconomic, and clinical factors with C-Reactive Protein (CRP) levels, an established marker of systemic inflammation, in African American breast cancer survivors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Design<\/jats:title>\n                    <jats:p>Exploratory pilot, cross-sectional study.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Setting<\/jats:title>\n                    <jats:p>NCI-designated Cancer Center.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Participants<\/jats:title>\n                    <jats:p>\n                      African American women (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200961) diagnosed with Stage I\u2013IIIa breast cancer who completed the UCLA Loneliness Scale and provided blood samples that were used to measure CRP as part of a laboratory-based study of stress reactivity.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Main outcomes and Measures<\/jats:title>\n                    <jats:p>The primary outcome was CRP level (mg\/L), and the primary predictor was the total score on the 3-item UCLA Loneliness Scale.

These findings underscore the need for greater conceptual clarity in distinguishing the components of social disconnection in relation to the inflammatory processes. Interventions addressing financial hardship, obesity, and multimorbidity management in survivorship care may help mitigate chronic inflammation and improve long-term health outcomes in a population that continues to experience breast cancer disparities.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s40615-026-03057-0","type":"journal-article","created":{"date-parts":[[2026,6,15]],"date-time":"2026-06-15T14:31:21Z","timestamp":1781533881000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Exploring Loneliness, Social Factors, and Clinical Correlates of C-reactive Protein in African American Breast Cancer Survivors"],"prefix":"10.1007","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-4652-6650","authenticated-orcid":false,"given":"Kelsie","family":"Campbell","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fatimata","family":"Sanogo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Trista A.","family":"Beard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melanie S.","family":"Jefferson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bodour","family":"Salhia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chanita Hughes","family":"Halbert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,6,15]]},"reference":[{"issue":"8","key":"3057_CR1","doi-asserted-by":"publisher","first-page":"2282","DOI":"10.3390\/cancers15082282","volume":"15","author":"MSU Ahmed","year":"2023","unstructured":"Ahmed MSU, Lord BD, Addai A, Singhal B, Gardner SK, Salam K, Yates AB, C.
