ARRA-Funded Obesity Studies
The increasing prevalence of overweight and obesity, especially among racial and ethnic minorities, is a serious public health concern. Today more than two-thirds of U.S. adults are overweight, and more than one-third are obese. The percentage of children and adolescents who have a high body-mass index (a measure of body weight in relation to height) has almost tripled during the past three decades and now stands at 16 percent. Excessive weight is associated with numerous adverse health outcomes, including heart disease and its risk factors (e.g., high cholesterol, high blood pressure, diabetes), sleep disorders, and lung diseases.
Achieving and Maintaining Weight Loss
Although many Americans indicate that they are trying to lose weight, most have trouble doing so, and many adults who are successful at shedding excess pounds eventually regain them. ARRA-funded grants that are exploring potential new approaches for achieving and maintaining weight control and thereby improving health include studies to:
Because reversing weight gain is problematic and often unsuccessful, prevention of overweight is critical. ARRA-supported research on prevention in various age groups includes studies to:
Understanding how fat cells and circulating fatty acids function may lead to more choices for weight loss and cardiovascular disease risk reduction. ARRA funds are supporting projects to:
