New type 2 diabetes more than doubles later stroke risk in this cohort.

Background

Whether type 2 diabetes (T2DM) accelerates age-related disease uniformly across organ systems or selectively in specific domains remains unresolved, as prior evidence comes largely from single-outcome studies.

Methods

Using SHARE (27 European countries, 2004-2020), we matched incident T2DM cases 1:1 to diabetes-free controls on age, sex, and survey wave, yielding six outcome-specific cohorts (n = 1,589-5,781).

n = 1,589

Results

Adults with new diabetes had over twice the stroke rate of matched diabetes-free peers.

HR 1.01 (95% CI 0.69 to 1.49)

CI crosses the null - not significant

More results

Age at diagnosis modified the associations for heart disease, stroke, cataract, and cancer (P-interaction < 0.05) but not for hypertension (P = 0.071) or arthritis (P = 0.154).

Conclusion · 1 of 2

T2DM accelerates age-related disease selectively; excess risk magnitude and its dependence on age at diagnosis differ substantially by outcome.

Conclusion · 2 of 2

These findings support risk stratification by organ system and diagnosis age rather than uniform comorbidity prevention strategies.
