What fasting plasma glucose level indicates prediabetes as a positive risk factor?

1. Fasting plasma glucose greater than or equal to 90

2. Fasting plasma glucose greater than or equal to 100 but less than 126

3. Fasting plasma glucose greater than or equal to 130

4. Fasting plasma glucose greater than or equal to 140

The correct answer is: Fasting plasma glucose greater than or equal to 100 but less than 126

A fasting plasma glucose level greater than or equal to 100 but less than 126 mg/dL is indicative of prediabetes. This range is significant because it reflects an intermediate state of glucose tolerance that can increase the risk of developing type 2 diabetes. The diagnostic criteria for diabetes and prediabetes have been established by organizations such as the American Diabetes Association, which defines prediabetes as a fasting plasma glucose level in this specific range. A fasting plasma glucose level of less than 100 mg/dL is considered normal, while a level at or above 126 mg/dL would typically diagnose diabetes. Recognizing prediabetes is critical because it presents an opportunity for intervention through lifestyle modifications, such as diet and exercise, to prevent the progression to diabetes. Therefore, understanding these criteria is vital for personal trainers who need to assess clients’ health and recommend appropriate actions based on their glucose levels.
