The Diabetes Threat
Posted on by Dr. Francis Collins
The number of Americans diagnosed with type 2 diabetes rose from 1.5 million in 1958 to 18.8 million in 2010. That’s an increase of epidemic proportions. Even more disturbing, another 7 million Americans have type 2 diabetes, but don’t know it and, consequently, can’t take steps to control the disease. Altogether, over 8% of the U.S. population now has this potentially deadly metabolic condition.
- Type 2 diabetes wreaks havoc on the body by raising the levels of glucose in the blood, increasing the risk of blindness, heart disease, kidney failure, nerve damage, and even Alzheimer’s disease.
- Pre-diabetes is a condition in which blood glucose levels are higher than normal, but not high enough to be called diabetes. 79 million U.S. adults age 20 and older have pre-diabetes.
- NIH studies have shown that losing just 6–7% of body weight and increasing physical activity can prevent or delay pre-diabetes from progressing to diabetes. 85% of people with diabetes are overweight.
A View of the U.S. Obesity Epidemic
Posted on by Dr. Francis Collins
These snapshots reveal a very disturbing trend: the rise in obesity in the US from 1985 to 2010. Today one third of adults in the US are obese, another third are overweight.
Because obesity has risen to epidemic levels—causing devastating and costly health problems, reducing life expectancy, and provoking stigma and discrimination—the NIH has established the NIH Obesity Research Task Force to accelerate progress in obesity research. For example, why are some individuals more susceptible to obesity? Can knowledge of biology and behavior be leveraged to develop better intervention strategies? What strategies work? For whom? Can these approaches be scaled up?
