CDC: Only 20 Percent of U.S. Adults Meet Aerobic, Muscle-strengthening Requirements
Only about one in five U.S. adults meet the aerobic and muscle strengthening components of the federal government's Physical Activity Guidelines for Americans, according to a new report in the U.S. Centers for Disease Control and Prevention’s (CDC) Morbidity and Mortality Weekly Report. The guidelines call for a minimum of 2.5 hours of moderate-intensity aerobic activity each week, or 1.25 hours of vigorous-intensity aerobic activity, as well as at least two days of muscle-strengthening activities. About half of adults meet the aerobic minimums and 30 percent meet the muscle-strengthening requirements, which Carmen D. Harris, MPH, epidemiologist in CDC's physical activity and health branch, called “encouraging.” "This is a great foundation to build upon, but there is still much work to do,” she said. “Improving access to safe and convenient places where people can be physically active can help make the active choice the easy choice."

Hospital Programs Find Success in Cutting Antibiotic Prescriptions, Drug-resistant Bacteria
Hospital programs designed to decrease the number of prescriptions for antibiotics also successfully cut the number of drug-resistant bacteria, according to a new study in the Cochrane Library. Such bacteria, as well as the possibility of secondary infections, can leave patients especially at risk. "Antibiotic resistance is recognized worldwide as a public health problem that's just getting worse. Really around the world people are worried that we'll end up with bacteria that are resistant to the antibiotics we've got," said Peter Davey, MD, of the University of Dundee in Scotland. Researchers found that while persuasion/education programs were effective, actually restricting prescriptions saw more improved outcomes early on, which persuasion/education’s effectiveness catching up later. "We got good evidence that restrictive interventions work faster in terms of changing prescribing and microbial outcomes," he said. Read more on preventing antibiotic resistance.
Suicide Rate Up Significantly for Middle-aged Americans
Attempts to explain the dramatic increase in suicides by middle-aged Americans over the past decade have left many public health experts “dumfounded,” according to Lanny Berman, executive director of the American Association of Suicidology. "The best we can come up with is maybe this is the group most likely to be affected by the recession and unemployment and [home] foreclosure," he said. "It affected suicide rates both nationally and internationally." A new report from the U.S. Centers for Disease Control and Prevention reveals that suicides for people aged 35-64 rose by 28 percent from 1999 to 2010. For comparison’s sake, more Americans died by suicide in 2010 (38,364) than in car crashes (33,687). According to an agency news release: "Suicide is a tragedy that is far too common. The stories we hear of those who are impacted by suicide are very difficult. This report highlights the need to expand our knowledge of risk factors so we can build on prevention programs that prevent suicide,” said CDC Director Tom Frieden, MD. Read more on mental health.
