The STOP DIABETES study: when prevention works

Area of Science:

• Endocrinology
• Metabolic Disorders
• Preventive Medicine

Background:

• Diabetes prevention remains a significant public health challenge despite available treatments.
• Prediabetes increases cardiovascular disease risk, underscoring the need for early detection and intervention.
• The time lag between initial glycemic defects and diabetes complications necessitates prompt management.

Purpose of the Study:

• To evaluate the effectiveness of risk stratification and tailored interventions in preventing type 2 diabetes (T2D).
• To investigate the role of 1-hour plasma glucose concentration in early prediabetes detection.

Main Methods:

• The STOP DIABETES study enrolled individuals at risk for T2D, assessing them via a 2-hour, 75-g oral glucose tolerance test (OGTT).
• Participants were stratified into low, intermediate, and high-risk groups based on physiological responses.
• Interventions included lifestyle modifications and pharmacological treatments tailored to risk level.

Main Results:

• Individuals at intermediate and high risk showed the most significant reduction in T2D conversion rates.
• A subset of individuals who developed T2D had normal baseline glucose tolerance but a 1-hour plasma glucose concentration exceeding 155 mg/dL.
• Early detection of glycemic alterations allows for less intensive treatment and reduces long-term costs associated with diabetes and its complications.

Conclusions:

• Risk stratification using OGTT, particularly considering the 1-hour plasma glucose concentration, enables early detection of individuals at risk for T2D.
• Early identification and treatment of prediabetes can delay or prevent T2D onset and associated complications.
• Incorporating 1-hour plasma glucose measurement into OGTT can improve early prediabetes diagnosis and management strategies.
