The Association Between Sustained HbA1c Control and Long-Term Complications Among Individuals with Type 2 Diabetes: A...

Area of Science:

• Endocrinology
• Public Health
• Clinical Research

Background:

• Type 2 diabetes (T2D) presents a growing global health challenge with substantial human and economic costs.
• High costs are partly due to frequent diabetes-related complications.
• Understanding the link between glycemic control and these complications is crucial.

Purpose of the Study:

• To investigate the association between glycemic control and the occurrence of diabetes-related complications in individuals with T2D.
• To analyze data from a large patient cohort to identify specific complication risks.

Main Methods:

• Utilized the Optum Clinformatics® Data Mart (CDM) from 2007-2020.
• Classified adult T2D patients into sustained glycemic control (hemoglobin A1c [HbA1c] < 7%) or poor control (HbA1c ≥ 7%) groups.
• Assessed diabetes-related complications using the Diabetes Complications Severity Index and performed multivariable analyses.

Main Results:

• Sustained glycemic control (HbA1c < 7%) was linked to significantly lower odds of cardiovascular disease (OR=0.76), metabolic disease (OR=0.37), neuropathy (OR=0.62), nephropathy (OR=0.81), and peripheral vascular disease (OR=0.52).
• No significant association was found between sustained glycemic control and cerebrovascular disease.
• These associations were observed over a 5-year post-period.

Conclusions:

• Sustained glycemic control is associated with a significant reduction in the likelihood of developing major diabetes-related complications.
• Effective management of blood glucose levels is vital for mitigating long-term health risks in T2D patients.
• These findings underscore the importance of achieving and maintaining target HbA1c levels.
