CDC: Daily Caloric Intake Down, But Obesity Rates Still Rising
Obesity rates continue to climb despite the fact that U.S. adults are consuming fewer and fewer calories, according to a survey from the U.S. Centers for Disease Control and Prevention appearing in the American Journal of Clinical Nutrition. Average daily caloric intake dropped by 74 from 2003 to 2010, after rising 314 calories from 1971 to 2003. About 35 percent of U.S. adults are obese. "It's hard to reconcile what these data show, and what is happening with the prevalence of obesity," said co-author William Dietz, MD, former CDC director of Nutrition, Physical Activity and Obesity.

Agencies Outline Responsibilities for Restoring Public Transportation after a Disaster
The Federal Transit Administration (FTA) and the Federal Emergency Management Agency (FEMA) have signed a Memorandum of Agreement (MOA) that outlines the roles and responsibilities of both agencies in providing federal assistance to repair and restore public transportation systems in areas the president has declared a major disaster or emergency. “After disasters hit, our federal, state and local partners must be able to move quickly and make the necessary repairs to our nation’s transit systems, roads, rails and bridges,” said U.S. Transportation Secretary Ray LaHood. FEMA will continue to have primary federal responsibility for emergency preparedness, response and recovery in major disasters and emergencies. The new emergency relief authority provides FTA with primary responsibility for reimbursing emergency response and recovery costs after an emergency or disaster that affects public transportation systems and for helping to mitigate the impact of future disasters.

Exercise Can Improve Self-Control in Kids, Young Adults
Short bursts of exercise—such as a half hour of running—can help youth and young adults improve their self control, according to a new study in the journal British Journal of Sports Medicine. "Tests conducted immediately after short bouts of exercise showed a clear improvement among higher-order functions like self-control, a cognitive [brain] function that is really important for daily activities in terms of both social life and academic performance," said lead author Lot Verburgh, a doctoral candidate in the department of clinical neuropsychology at VU University in Amsterdam. The results could help in the treatment of disorders associated with impaired inhibition, such as attention-deficit/hyperactivity disorder (ADHD) and autism. Read more on exercise. If exercise can also be linked to long-term improvement in higher-order mental processes, exercise may soon be not only a treatment option for heart disease patients and individuals looking to control their weight, but also for ADHD and Alzheimer's patients," said Ali Weinstein, an assistant professor and deputy director of the Center for Study of Chronic Illness and Disability at George Mason University in Fairfax, Va.
