Heavyweight Teens May Face Diabetes Down the Road, New Swedish Study Shows
It turns out that the teenage puff‑up can leave a lasting scar on the body. A Swedish team followed more than 36,000 men from nursery school through middle age and found that boys who nabbed a few extra pounds during puberty are far more likely to develop type 2 diabetes later in life.
How the Study Was Run
- • 36,176 men were measured for body mass index (BMI) at age 8 and again when 20.
- • Researchers tracked medical records starting at age 30—averaging almost 30 years of follow‑up.
- • During that time, 1,777 of the men were diagnosed with diabetes.
The Big Take‑Away
- • Kids who were overweight at 8 but “back to normal” by 20 bailed out the risk—no higher chance of diabetes than those who stayed lean the whole time.
- • The plot thickens for those who jumped from a healthy weight straight into the overweight zone during puberty. Those guys were 4× more likely to get diabetes before 55 and 2× more likely after 55, compared to never‑overweight childhood teammates.
Scientists Speak It Out
Dr. Elif Arioglu Oral, a Michigan diabetes researcher, summed it up: “The change in weight status during puberty adds a fresh, independent risk—more than just being heavy as a kid.” Oral advises parents to “encourage kids who hit puberty with an uptick in BMI to work on trimming up during those years.”
Dr. Jenny Kindblom from Gothenburg notes, “We’re still scratching our heads about why this happens, but puberty‑related weight gain probably pushes fat into the belly, a notorious diabetes risk factor.”
What the Numbers Say
- • 6.2 % were overweight at 8; 7.4 % at 20.
- • About 58 % of those overweight as kids were lean by adulthood.
- • Roughly 64 % of men overweight at 20 had been lean at 8.
The Bottom Line for Parents
Dr. Mark DeBoer (Virginia) urges a family‑based approach: “Kids need tasty veggies, fewer saturated fats, and a dose of regular exercise—ideally, the whole squad pulls together.”
This fresh evidence nudges everyone to keep an eye on kids’ weight curves during their dramatic teenage years. Staying on the lean track could be the key to a sweeter future—literally, without the sugar spike of diabetes.
