Life's Essential 8 and Suicide Risk: A Population-Level Study of Cardiovascular Health as a Mental Health Indicator.
Article in Psychiatry investigation, 2026. 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
objectiveCardiovascular health (CVH), assessed through Life's Essential 8 (LE8), has been widely studied in relation to physical health outcomes. However, its association with mental health, including psychological distress, suicidal behavior, and mental health service utilization, remains underexplored. This study examined whether better CVH is associated with reduced risk of mental health problems and greater engagement with mental health services.
methodsWe conducted a cross-sectional analysis using data from 4,106 Korean adults aged ≥19 years from the 2021 Korea National Health and Nutrition Examination Survey. CVH was measured using LE8 and categorized into low (0-49), moderate (50-79), and high (80-100) groups. Mental health outcomes included perceived stress, depressive mood, suicidal ideation, suicide planning, suicide attempts, and mental health service utilization.
resultsHigher LE8 scores were significantly associated with lower stress (p=0.041) and reduced odds of suicidal ideation (p=0.001). Compared to the low CVH group, adjusted odds ratios (ORs) for stress perception were 0.748 (95% confidence interval [CI]: 0.587-0.953) in the moderate group and 0.685 (95% CI: 0.491-0.956) in the high group. For suicidal ideation, the ORs were 0.517 (95% CI: 0.329-0.813) and 0.199 (95% CI: 0.078-0.507), respectively. LE8 health behaviors, not health factors, were significantly associated with stress perception and suicidal ideation.
conclusionBetter CVH is associated with lower psychological distress and suicidal behavior, with health behaviors in LE8 showing stronger associations with mental health outcomes than health factors. Further longitudinal studies are needed to confirm causality and underlying mechanisms.
