Behavioral Components of Life's Essential 8 Are More Strongly Associated with Cognitive Function than Clinical Factors in Chinese Older Adults.
Article in International journal of behavioral medicine, 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
backgroundCardiovascular health is increasingly recognized as a key determinant of cognitive aging. The American Heart Association recently introduced Life's Essential 8 (LE8), integrating both behavioral and clinical components of cardiovascular health. However, the relative contributions of behavioral versus clinical factors to cognitive outcomes remain unclear, particularly in Chinese older adults.
methodsThis study included 2,527 participants aged ≥ 65 years from the Ma'anshan Healthy Aging Cohort. Weighted linear and logistic regression models were used to examine the associations of LE8 scores with cognitive function and mild cognitive impairment (MCI). Restricted cubic spline (RCS) models were applied to assess dose-response relationships. Subgroup and sensitivity analyses were conducted.
resultsHigher LE8 scores were significantly associated with better cognitive function and lower risk of MCI. Each 10-point increase in LE8 score was associated with a 0.532-point higher MMSE score (95% CI: 0.353-0.712, P < 0.001) and a 16.5% lower risk of MCI (OR = 0.835, 95% CI: 0.742-0.945, P = 0.004). Notably, behavioral components-including diet, sleep, and physical activity-demonstrated more robust and pronounced associations with cognitive outcomes than clinical factors such as blood glucose and lipids. Dose-response analyses indicated significant linear relationships. Subgroup analyses suggested possible heterogeneity by sex and depressive status; findings were robust across sensitivity analyses.
conclusionsBehavioral aspects of cardiovascular health appear to play a dominant role in cognitive function among older adults. These findings highlight the importance of modifiable health behaviors as potential targets for preventing cognitive decline and support behavior-focused strategies in healthy aging.
