Prospective associations between psychosocial stress and the risk of type 2 diabetes in middle-aged adults: findings from the KoGES_CAVAS.
Article in Epidemiology and health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesPsychosocial stress is a potential risk factor for type 2 diabetes (T2D); however, the influence of the timing of stress exposure remains uncertain. We examined the prospective associations of baseline, cumulative average, and recent psychosocial stress with the risk of incident T2D in middle-aged adults.
methodsWe analyzed data from 7,880 participants aged 40-64 years without T2D at baseline. Psychosocial stress was assessed repeatedly using the Psychosocial Well-Being Index-Short Form. Incidence rate ratios (IRRs) and 95% confidence intervals (CIs) were estimated using modified Poisson regression models with robust error estimators.
resultsA total of 437 T2D cases occurred over 47,621 person-years. While baseline stress showed a non-significant association, both cumulative and recent stress demonstrated positive associations with T2D risk. Recent stress exhibited the strongest association in both male (stress vs. healthy group: IRR, 2.23; 95% CI, 1.41 to 3.52; highest [T3] vs. lowest tertile [T1]: IRR, 1.50; 95% CI, 1.07 to 2.10) and female (stress vs. healthy group: IRR, 1.72; 95% CI, 1.11 to 2.66; T3 vs. T1: IRR, 1.73; 95% CI, 1.26 to 2.37). These associations were more pronounced among participants with abdominal obesity, showing a significant positive linear trend (Bonferroni-corrected threshold, p=0.003).
conclusionsRecent psychosocial stress was associated with an increased incidence of T2D, underscoring the importance of integrating psychosocial factors into diabetes prevention strategies, particularly for individuals with abdominal obesity.
