Key result
Five reproducible diabetes subtypes link to distinct complication burdens in a high-altitude population.
Why the study?
Evidence for established data-driven diabetes subtypes in high-altitude populations is limited.
Cross-Sectional (n=514)
Data-driven diabetes subtypes are reproducible in high-altitude populations and correlate with specific complications like albuminuria and peripheral arterial disease.
Subtypes may inform complication risk in high-altitude diabetes; extends established classifications but requires prospective validation.
Introduction and Objective: Evidence for established data-driven diabetes subtypes in high-altitude populations is limited. We examined subtype reproducibility and associations with complications in a high-altitude population. Methods: We conducted a cross-sectional analysis of 514 adults with diabetes in the Xizang Autonomous Region, China. Participants were classified into 5 subtypes (SAID, SIDD, SIRD, MOD, and MARD) using a sex-specific nearest-centroid approach. Complication associations were evaluated by logistic regression adjusted for age, sex, diabetes duration, and smoking. Results: All 5 subtypes were reproduced with distinct phenotypes. Subtype-specific associations with albuminuria and peripheral arterial disease were observed. Conclusion: Established diabetes subtypes are reproducible in a high-altitude population and exhibit distinct phenotypes with differential complication burdens.
