摘要

Purpose

To assess the association between hypoglycemia exposure and the risk of developing microvascular diseases (MVDs) in type 2 diabetes patients via continuous glucose monitoring (CGM), aiming to identify optimal hypoglycemia thresholds for improved glucose management.

Methods

A total of 174 type 2 diabetes patients underwent 2 weeks of CGM. Binary multivariate logistic regression assessed the association between hypoglycemia exposure and MVDs prevalence at thresholds of 3.0-3.9 mmol/L.

Results

After 14 days of monitoring, 79.9% of patients experienced hypoglycemia. The MVDs group had a significantly greater percentage of participants with hypoglycemia (glucose < 3.4 mmol/L: 57.6 vs. 39.8%, P = 0.023) and nocturnal hypoglycemia (glucose < 3.9 mmol/L: 62.1 vs. 46.3%, P = 0.043), with no significant difference in daytime hypoglycemia. After adjustment for confounders, only nocturnal hypoglycemia was independently associated with the risk of developing MVDs, and the prevalence of MVDs was positively associated with hypoglycemia severity. When the hypoglycemia threshold was reduced from 3.4-3.0 mmol/L, the odds ratio increased from 1.342 (1.026, 1.798) to 1.855 (1.141, 3.457). Further subgroup analysis revealed that nocturnal hypoglycemia below 3.4 mmol/L was a risk factor for the development of retinopathy and neuropathy (P < 0.05) but not for nephropathy.

Conclusion

Nighttime glucose levels below 3.4 mmol/L are strongly associated with a greater risk of developing retinopathy and neuropathy in type 2 diabetes patients. Thus, blood glucose management should be time-specific, with daytime levels maintained above 3.9 mmol/L and nighttime levels maintained above 3.4 mmol/L.
