Abstract
Purpose
Time in range (TIR) has surfaced as a key continuous glucose monitoring (CGM)—derived metric, which was linked to diabetes-related outcomes. We aimed to investigate the association of TIR with the risk of lower extremity atherosclerotic disease (LEAD) among patients with type 2 diabetes.
Methods
A total of 1351 adult patients with type 2 diabetes were prospectively recruited from a single center in Shanghai, China. TIR was obtained from CGM data at baseline. LEAD was measured with color Doppler ultrasonography. Cox proportion hazard regression analysis was used to assess the association between TIR and the risk of incident/progressive LEAD.
Results
During a median follow-up of 7.4 years, 450 participants developed incident/progressive LEAD. The multivariable-adjusted hazard ratios (HRs) for incident/progressive LEAD across different levels of TIR ( > 85%, 71~85%, 51~70%, and ≤50%) were 1.00, 1.15 (95% confidence interval [CI] 0.87–1.52), 1.37 (95% CI 1.04–1.80) and 1.46 (95% CI 1.10–1.94) (P for trend = 0.004), respectively. With each 10% decrease in TIR, the multivariable-adjusted risk of incident/progressive LEAD increased by 7% (95% CI 1.02–1.11). Similar results were found in the association between TIR and incident LEAD as the secondary outcome (P for trend < 0.001).
Conclusions
The current study found an inverse association of TIR with the risk of LEAD among patients with type 2 diabetes.
