Summary
7 papers analyzed
These studies suggest that pre-diabetes is a condition characterized by an increased risk of developing type 2 diabetes and cardiovascular disease, and it can be managed and potentially prevented through lifestyle modifications, weight loss, physical activity, and sometimes pharmacotherapy.

Understanding the Pre-Diabetic Range: Definitions, Prevalence, and Management
Definition of Pre-Diabetes: Key Diagnostic Criteria
Pre-diabetes is a metabolic condition where blood glucose levels are elevated above normal but not high enough to be classified as diabetes. It is identified through several diagnostic criteria, including impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and elevated glycosylated hemoglobin (HbA1c). According to the American Diabetes Association (ADA), IFG is defined as fasting glucose levels between 100-125 mg/dL (5.6-6.9 mmol/L), IGT as 2-hour plasma glucose levels between 140-199 mg/dL (7.8-11.0 mmol/L) during an oral glucose tolerance test (OGTT), and HbA1c levels between 5.7-6.4% .
Prevalence of Pre-Diabetes: Global and Regional Insights
Pre-diabetes is highly prevalent worldwide, affecting various populations differently. In the Middle East and North Africa (MENA) region, the weighted prevalence of pre-diabetes in women of childbearing age is approximately 7.6%. In the UK, it is estimated that 1 in 3 adults fall into the pre-diabetic category, primarily diagnosed through HbA1c levels. Among U.S. adolescents, the prevalence of pre-diabetes is about 16.1%, with higher rates observed in boys and overweight individuals.
Ethnic Variations in Pre-Diabetes Prevalence
The prevalence of pre-diabetes varies across ethnicities. Studies indicate that Caucasians have a higher prevalence of isolated IFG, while Asians show higher rates of isolated IGT and combined IFG & IGT. These differences highlight the need for tailored diagnostic and management strategies across different ethnic groups.
Risk Factors and Associated Conditions
Pre-diabetes is often associated with other metabolic conditions such as obesity, metabolic syndrome, and hyperinsulinemia. Insulin resistance and systemic inflammation due to obesity are common underlying factors. Adolescents with hyperinsulinemia have a significantly higher prevalence of pre-diabetes, indicating a strong link between insulin resistance and the condition.
Management and Prevention Strategies
Effective management of pre-diabetes involves lifestyle modifications such as healthy dietary practices, regular physical activity, and weight loss. Pharmacotherapy, particularly with metformin, can also be beneficial, although lifestyle changes have shown more sustainable effects . Preventive measures are crucial as 5-10% of pre-diabetic individuals progress to diabetes each year.
Conclusion
Pre-diabetes is a critical health condition that serves as a precursor to type 2 diabetes and is associated with various cardiometabolic risks. Understanding its diagnostic criteria, prevalence, and effective management strategies is essential for preventing the progression to diabetes and associated complications. Tailored interventions based on individual risk factors and ethnic variations can significantly improve outcomes for those at risk.
