Research Topics


Obesity and overweight refer to a range of weights greater than is considered normal and healthy. Both conditions have been shown to increase the likelihood of certain diseases, including Type 2 diabetes, hypertension, and heart disease. Important issues related to obesity and overweight that are being studied include incentive strategies for long-term weight loss, implementation of obesity prevention initiatives, and the efficacy and cost-effectiveness of certain treatments such as bariatric surgery.
