According to a startling study published in JAMA Pediatrics, about 28% of adolescents in the United States now qualify as having prediabetes, prompting serious concerns regarding the effectiveness of current screening protocols and preventative strategies. The research, which examined data from ten cycles of the National Health and Nutrition Examination Survey for youths aged 12 to 19 from 1999 to 2018, revealed a significant increase in prediabetes rates, soaring from 11.6% to 28.2% overall. While older teens (ages 16-19), males, and those with obesity showed higher prevalence, the surge in prediabetes cases was consistent across all genders, races, and weight categories.
“These statistics are alarming, and it’s evident that without intervention, we will face a substantial rise in diabetes among our youth,” states study co-author Nathan Reed. It’s important to note that the data was collected prior to the onset of the pandemic. Given that children, similar to adults, have been shown to gain weight on average during this time, along with an increase in sedentary lifestyles and poor dietary habits, it is likely that the current numbers of prediabetes cases among adolescents are even higher.
Prediabetes indicates an increased risk of developing type 2 diabetes, but the good news is that it can be reversed with lifestyle modifications such as improved diet, increased physical activity, and weight loss. The study utilized A1C levels and fasting glucose measurements to diagnose prediabetes, excluding the glucose tolerance test often associated with a sugary beverage some may remember from their pregnancy screenings. The A1C test, or HbA1c, reflects average blood sugar levels from the previous two to three months. Normal levels are up to 5.7%, while prediabetes is defined as 5.7% to 6.4%, and diabetes is indicated by levels of 6.5% or higher. Additionally, a fasting blood glucose level of 100-125 is used to diagnose prediabetes.
From 1999 to 2018, the rate of prediabetes in males climbed from 15.8% to 36.4%, while in females it increased from 7.1% to 19.6%. Among adolescents with normal or underweight status, the rates rose from 9.41% to 24.3%. In overweight teens, the rates jumped from 15.3% to 27.5%, and for obese adolescents, the figures surged from 18.2% to 40.4%. The increase in younger adolescents, ages 12-15, was from 13.1% to 30.8%; in older teens, ages 16-19, it rose from 10.0% to 25.6%.
The American Diabetes Association states that lifestyle changes are typically more effective than medications like Metformin in delaying the progression to diabetes. Alarmingly, nearly 100 million adults in the U.S. — about one in three — also show signs of prediabetes, indicating a widespread problem that extends beyond teens. While it’s easy to blame poor dietary choices and inactivity, many of these issues are systemic, stemming from factors like unhealthy school lunches, reduced physical education programs, food deserts in urban areas, and inadequate wages. Additionally, a healthcare system that does not prioritize preventive care for children exacerbates the issue. Significant changes are necessary at both individual and societal levels to combat this crisis.
