Neurocognitive aging
Does crossing the digital divide protect late-life cognition?

In 10,098 BABRI participants, digital exclusion tracked with worse processing speed and higher MCI risk; overcoming it linked to slower decline and MCI reversion.

Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
Community cohorts link digital access gaps to cognitive disparities in older adults.
A community-based cohort analysis examines how digital divide measures relate to cognitive outcomes in older adults.
Evidence for the claim as stated.
ADL limits track higher late-life depression risk.
In CHARLS older adults, BADL/IADL limitations associated with roughly 2.7× adjusted odds of high-risk depressive symptoms—functional health alongside digital access.
Scope note — depression/ADL ≠ digital-access cognitive disparity endpoint
Limits the claim's scope: a different population, assay, or outcome.
Brain network connectivity helps maintain cognition across aging.
Extrinsic and intrinsic network connectivity findings show systems-level support for cognition across age—neural maintenance context for disparity studies.
Scope note — connectivity maintenance ≠ digital divide exposure measure
Limits the claim's scope: a different population, assay, or outcome.
Digital-access disparities, ADL–depression associations, and connectivity maintenance speak to related aging problems without proving one common intervention.

48.9% (4941/10098) faced the digital divide.
Among the 10098 participants, nearly half (n=4941, 48.9%) faced the digital divide, which was associated with a worse performance in processing speed (F 10096 =10.67; P <.001; effect size r =0.42)
Overcoming the digital divide associated with MCI HRs of 0.5 and 0.43.
overcoming the digital divide was also associated with a lower risk of developing MCI (hazard ratio [HR] 0.5, 95% CI 0.34-0.74; HR 0.43, 95% CI 0.29-0.62)
Key findings
48.9% faced the divide; strongest cross-sectional hit was processing speed (r=0.42). Overcoming the divide associated with lower MCI HRs (~0.43–0.5) and higher reversion HRs (~6–9).
Methodology
Quantified ICT use (digital divide), then used ANCOVA, mixed models, and Cox models relating divide status to multidomain cognition and MCI transitions.
Limitations
That giving internet access alone causally prevents dementia; residual confounding by SES/health remains possible.
