New CDC data shows nearly 1 in 3 teens had prediabetes in 2023. Dr. Celine Gounder joins "CBS Mornings" to explain what's driving the rise and what it means for long-term health.

Washington

New data from the Centers for Disease Control and Prevention (CDC) indicates that nearly 33% of American teenagers aged 12 to 17 had prediabetes in 2023, a significant rise from previous years. This increase is linked to factors such as sedentary lifestyles, poor diet, insufficient sleep, and high stress, as well as recent cuts to public health programs supporting nutrition and physical activity.

Medical experts stress that prediabetes in teens often presents no symptoms but signals a higher risk for developing type 2 diabetes, heart disease, and stroke later in life. They recommend family-wide changes in diet and activity, emphasizing the importance of parental role modeling and small, sustainable steps to improve health outcomes.

Sharp rise in prediabetes among teens raises long-term health concerns

In today's Health Watch, we are looking at new concerns about rising pre-diabetes rates among American teenagers. The CDC estimates nearly 33% of kids, wow that's a lot, ages 12 to 17 had pre-diabetes in 2023. That's nearly double the estimate in 2019. Pre-diabetes puts teens at future risk for type 2 diabetes, heart disease and stroke. Joining us now is CBS News medical contributor, Dr. Selene Gounder. She is also editor-at-large for Public Health at KFF Health News. Dr. Gounder, thank you so much for being here to talk about this. Good morning. So what's going on? What's driving the spike? It's a great question. So we know that people in this country, including teens, have relatively sedentary lifestyles. We're eating too much salt, sugar and fat and ultra-processed food. Teens are also not getting enough sleep and they're under a lot of stress. And all of these things lead to increased weight gain and the risk for diabetes. On top of that, we've recently seen CDC cuts to programs that support things like school nutrition, farmers markets, walking trails in communities. And so some of the things that we're trying to address these issues have actually been scaled back. So what are the warning signs? The warning signs, there are actually no symptoms of pre-diabetes. Pre-diabetes, pre, means you don't have diabetes. Your blood sugar levels are not normal, they're a little bit above normal. But you're not seeing the health effects of this yet. And so this is really a warning sign and an opportunity to take action. So can it be reversed if you are diagnosed with pre-diabetes? That's a great question. Yes, so if you take actions in terms of exercise, changing your diet, getting better sleep, reducing stress, you can certainly reduce your risk of progression to diabetes. So sometimes how you parent, how you feed your kids is passed down. We're just products of what we are around and exposed to as kids. So what can parents do now, even though that they might have been in a different type of environment growing up, to kind of change that generational issue? Well, I think this is super important because role modeling is a big part of what parents should be doing. So it's not enough to tell your kid, go out for a run or eat better. You need to do it yourself. And you need to be cooking meals, preparing meals for the whole family that are good for you as well as your kids. What do you mean good for you? What types? Are you talking about fresh produce? Yeah, and I think it's important to recognize we talk about diet and exercise almost every day here, right? For decades we've been talking about these. There are very good reasons people don't do these things, right? It's comfort food, it's time, it's finances. But trying to take even little steps to improve diet, improve exercise for the whole family, reducing your ultra processed foods might be one step. Cutting out added sugars. Cutting out added sugars. Chips out of the house. Exactly. Shop along the edges of the grocery store. That's a good point. That's where all the fruits and vegetables are. That's right. Dr. Celine Gounder, always great to have you. Thank you very much.
