Objective:

To estimate the percentages of US adults with diabetes who reported knowing their recent HbA1c, BP, and LDL-cholesterol levels and goals, and to identify characteristics such as demographics and health behaviors associated with this knowledge.

Key Findings:
  • Only 50.5% of US adults with diabetes achieved the recommended HbA1c target, highlighting a critical gap in diabetes management.
  • 70.4% had controlled blood pressure, and 60.3% had LDL-cholesterol levels below 100 mg/dL, indicating varying levels of awareness and control.
  • A significant portion of adults with diabetes were unaware of their HbA1c, BP, and LDL-cholesterol levels, which may impact their health outcomes.
Interpretation:

The findings indicate a significant gap in awareness among adults with diabetes regarding their critical health metrics, which may hinder effective self-management and increase the risk of complications, emphasizing the need for improved patient education.

Limitations:
  • The study relies on self-reported knowledge, which may not reflect actual levels and could introduce bias.
  • Data does not assess the accuracy of reported levels and goals.
Conclusion:

Improving awareness of HbA1c, BP, and LDL-cholesterol levels among adults with diabetes is crucial for enhancing self-management and reducing health risks.
