A 2026 cross-sectional study in Moshi, Tanzania found that only 26 of 246 injury patients who drank alcohol, or 10.6%, had ever told a healthcare provider about their alcohol use.1 The calibration result was contrary to the prediction: measured alcohol stigma did not track disclosure, while alcohol-related consequences did.

A 2026 cross-sectional study involving 428 employed adults found that poor sleepers reported a median 292.8 mg/day of caffeine, compared with 176.1 mg/day among good sleepers, and total caffeine intake still predicted higher Pittsburgh Sleep Quality Index scores after adjustment (β = 0.147, p = 0.003). The source breakdown is the useful part: black coffee, …
A 2026 participatory-design and case-study paper turned smartphone mental-health data into 6 clinician-facing visualizations for an 8-week anxiety/depression digital clinic, using feedback from 15 clinicians and 3 clinical supervisors. The useful claim is workflow-level: charts made passive sensing and symptom ratings discussable inside care, but the paper did not test whether the visualizations improved clinical …
A 2026 Singapore birth-cohort preprint found a conditional childhood-anxiety signal: the cord-blood DNA methylation component predicted less age-13 anxiety only in boys in the low DMN-limbic trajectory group from ages 4.5 to 10.5 years. The paper is useful for mapping developmental risk biology, but it is not a screening test and it does not show …

Research Highlights Same weight loss, harsher judgment: Tissot et …

A 2025 longitudinal analysis of 1,528 older Chinese Americans by Chen et al. in the Journal of Prevention of Alzheimer’s Disease says something more specific than “stress causes Alzheimer’s”: it isn’t the count of stressors that tracks memory decline — it’s a latent trait the authors call stress internalization, a bundle of high perceived stress, …
