High-Altitude Renal-Metabolic Stress and Albuminuria in Hospitalized Patients With Diabetes in Tibet.

Among 724 patients with albumin-to-creatinine ratio data, albuminuria and macroalbuminuria were present in 306 (42.3%) and 102 (14.1%).

Severe stress (score ≥ 3) showed a stronger association with macroalbuminuria.

Results were broadly consistent after estimated glomerular filtration rate adjustment, alternative score definitions and extended available-confounder adjustment.

High hemoglobin with high RDW identified a subgroup with greater albuminuria burden.
