Associations between perceptions of relationship quality and markers of inflammation and insulin resistance among couples coping with cancer.
Article in Journal of cancer survivorship : research and practice, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03630354 (EXERCISING TOGETHER © for Couples Coping With Cancer), which is not on this map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
Among married couples living with breast and prostate cancer, positive perceptions of relationship quality by both survivors and their spouses were associated with lower inflammation or insulin resistance in their partner. Our data support evidence that health within couples is both interdependent and transactional and suggests that one member's perception of the relationship is associated with biologic changes in one's partner, leading to better physical health of the couple. These findings may provide a biologic underpinning to observations of an inverse relationship between relational satisfaction and overall mortality and underscore the need for a dyadic approach to health. PURPOSE: Couples' health and health behaviors are intertwined, where the health of one partner can influence the health of the other but the biologic underpinnings are not known. We examined the associations between relational health and markers of inflammation and insulin resistance in couples coping with breast or prostate cancer.
methodsParticipants (90 cancer survivor-spouse dyads) completed self-report measures of relational health including Dyadic Adjustment Scale-7 (relationship quality), Dyadic Coping Inventory (communication), and shared physical activity, as well as Community Health Activities Model Program for Seniors (individual physical activity). Inflammation (C-reactive protein (CRP)) and homeostasis model assessment of insulin resistance (HOMA-IR) were measured in serum samples. Structural equation modeling including demographic and clinical covariate controls was used to estimate separate actor and partner effects of relationship quality, communication, and physical activity on CRP and HOMA-IR.
resultsParticipants were aged 63.1 ± 10.4 years with an average relationship duration of 30.0 ± 1.1 years. Higher survivor perceived relationship quality was associated with lower spouse CRP (b = - 0.07; 95%CI: - 0.13, - 0.01), whereas higher spouse perceived relationship quality was associated with lower survivor HOMA-IR (b = - 0.07; 95%CI: - 0.13, - 0.03). There were no other significant actor or partner effects observed.
conclusionsAmong cancer survivor-spouse dyads, how one member of the couple perceives the quality of the relationship impacts disease biomarkers in the other, providing preliminary evidence for biological linkage between relational health and chronic disease risk. IMPLICATIONS FOR CANCER SURVIVORS: Relationship quality may positively influence biomarkers of inflammation and insulin resistance in couples coping with breast and prostate cancer. Dyadic approaches to optimize survivorship health may be warranted.
