Many Young Teens Destined to Have Diabetes

Study: 40% of 8th Graders Have Prediabetes

WebMD Health News

June 4, 2004 -- Type 2 diabetes is the destiny of many young teens, a U.S. study predicts.

The NIH-funded survey sampled 1,700 eighth-grade kids in Houston, North Carolina, and Southern California. More than half were Hispanic, and a fourth were African American -- U.S. groups at particular risk for type 2 diabetes.

The young teens underwent a battery of tests. Only 0.4% of the kids already had type 2 diabetes. But:

  • More than 40% of the kids had prediabetes -- that is, blood sugar levels that are above normal yet not high enough to be type 2 diabetes.
  • About 14% had metabolic syndrome, a combination of abdominal fat, abnormal fat and cholesterol levels in the blood, high blood pressure, and high blood sugar. Metabolic syndrome is a serious condition that, unless corrected, vastly increases a person's risk of diabetes, heart disease, and stroke.
  • Half the teens were seriously overweight or at risk of being overweight.
  • Nearly half the kids had too-low levels of good HDL cholesterol.
  • Nearly one in five boys and one in 10 girls had high blood pressure.

"These data demonstrate high levels of obesity, pre-diabetes, and the metabolic syndrome among middle school children," the researchers note.

Is diabetes these teens' destiny? Not necessarily. The current findings represent the first phase of the study, which is testing ways to prevent type 2 diabetes.

Your level is currently

If the level is below 70 or you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.

People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.

Congratulations on taking steps to manage your health.

However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.

Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.

Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.

One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
