About obesity and diabetes research

 

Over the past several decades, obesity has grown into a major global epidemic. In the United States, rates of obesity have doubled since 1970 to over 30%, with more than two-thirds of the adult population now overweight. Over 15% of children in the U.S. are obese. Obesity is linked with higher risks for several serious health conditions including type 2 diabetes, coronary artery disease, hypertension, high cholesterol, and stroke. Presently, more than 24 million people in the U.S. have diabetes, a number that has doubled in the past decade and it is now estimated that one-third of the children born today will develop diabetes in their lifetime. Diabetes is the leading cause of complications such as retinopathy, nephrology, and peripheral nerve disease as well as amputations.

Is this option for me?

 

This option is for students who wish to study the causative factors of obesity and diabetes, as well as the effects of the conditions on the human body.
