CDC Outlines Increase in Prediabetes Cases in Adolescents between 12 and 17 years Old
A new analysis by the Centers for Disease Control and Prevention (CDC) reveals that prediabetes, a condition that precedes type 2 diabetes, is more widespread among American adolescents than previously estimated. The findings underscore the importance of earlier interventions to address the rising prevalence of prediabetes and its associated long-term health risks.
Screening Guidelines for Adolescents
The recommended screening guidelines for prediabetes in adolescents in the U.S. focus on risk-based screening starting at age 10 or after the onset of puberty. This is particularly important for those who are overweight or obese and have one or more additional risk factors for diabetes, such as a family history of type 2 diabetes, signs of insulin resistance, or certain ethnic backgrounds with higher diabetes risk.
The primary screening tests include fasting plasma glucose (FPG), glycated hemoglobin (HbA1c), and an oral glucose tolerance test (OGTT) when indicated.
The Importance of Early Detection
Early identification of prediabetes enables lifestyle interventions to prevent progression to type 2 diabetes. Prediabetes typically occurs without symptoms, especially in younger populations, which means many adolescents and their families may be unaware of the metabolic changes occurring.
Long-term health risks associated with prediabetes include progression to type 2 diabetes, heart disease, and kidney complications. Health experts are urging increased screenings and better public awareness for prediabetes, especially for at-risk groups.
The CDC's Analysis
The CDC's latest analysis is based on data collected from the National Health and Nutrition Examination Survey (NHANES), a nationally representative sample that combines interviews, physical exams, and laboratory testing. The analysis used updated FPG calibration methods to ensure accuracy across multiple NHANES data collection cycles.
The findings reveal that nearly 1 in 5 American adolescents between the ages of 12 and 17 have prediabetes. To confirm diabetes status, the researchers relied on both interview responses and lab results. Adolescents were classified as diabetic if they either answered "yes" to having been diagnosed by a healthcare provider or had lab-confirmed results with FPG ≥126 mg/dL or A1c ≥6.5%.
Addressing the Epidemic
The silent epidemic of prediabetes among American adolescents requires urgent attention. Lifestyle factors like sedentary behavior, poor diet, and obesity continue to rise among youth populations, posing a significant concern for public health.
The CDC and other public health organizations have long recommended increased screening for children with risk factors such as obesity, family history of diabetes, or signs of insulin resistance. However, the new analysis reveals that the issue of prediabetes among American adolescents is more widespread than previously estimated.
In conclusion, the current best practice is risk-based screening starting around age 10 or puberty, using blood glucose markers and considering body weight and additional risk factors to guide who should be screened. The findings underscore the urgent need for earlier interventions due to the rising lifestyle factors among youth populations.
