Life's essential 8 health profiles and risk of incident neuropsychiatric diseases: a nationwide prospective cohort study.
Article in BMC psychiatry, 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
backgroundAlthough previous studies have established associations between Life's Essential 8 (LE8) and neuropsychiatric diseases, they predominantly operationalised the LE8 as a composite score, assuming equal weighting and potentially obscuring heterogeneity in health behaviour patterns. Therefore, this study applied latent profile analysis (LPA) to identify distinct LE8 profiles and examined their associations with the incidence of neuropsychiatric diseases.
methodsThe sample comprised 242,947 UK Biobank participants without prevalent neuropsychiatric diseases. LE8 comprises eight components: healthy diet, physical activity, nicotine exposure, sleep health, glucose, blood lipid, blood pressure, and body mass index. LPA was utilized to identify distinct health patterns. Cox proportional hazards models were used to examine the associations between LE8 profiles and disease incidence.
resultsLPA identified five distinct profiles: Low LE8 score; Elevated adiposity, blood pressure, and glucose group; Low physical activity with poor sleep group; Elevated blood pressure and dyslipidaemia group; and High LE8 score group. Over a median follow-up of 13.8 years, 11,419 cases of anxiety, 341 cases of bipolar disorder, and 40 cases of schizophrenia were identified. Using the Low LE8 score group as a reference, all four comparison profiles exhibited significant protective associations for both anxiety (Hazard Ratio [HR] range: 0.65-0.78, all p < 0.001) and bipolar disorder (HR range: 0.37-0.51, all p < 0.001), with risk reductions of up to 35% and 63%, respectively. No significant associations were observed for schizophrenia, likely due to the small number of incident cases (n= 40), and these findings should be considered exploratory.
conclusionsDistinct LE8 profiles showed heterogeneous associations with neuropsychiatric disease risk, with healthier profiles linked to lower anxiety and bipolar disorder risk, while schizophrenia findings remained inconclusive. These results support person-centred, pattern-based approaches over composite scoring for neuropsychiatric risk stratification and hypothesis generation. CLINICAL TRIAL NUMBER: Not applicable.
