Young Blacks Living in Public Housing More Likely to be Smokers
A recent survey in three urban cities by a University of Missouri researcher found that young African-Americans who live in public housing communities are 2.3 times more likely to use tobacco than other African-American youth. The researchers say crime, poorer social relationships and high levels of stress may contribute to the increased smoking rate. The study was published in the journal, Addictive Behaviors.

Study: Medicaid Expansion Improves Health
A new study in the New England Journal of Medicine by researchers at the Harvard School of Public Health found that expanding Medicaid to low-income adults leads to widespread gains in coverage, access to care, improved health and mortality reduction.
In the past decade, several states expanded Medicaid from its traditional coverage of low-income children, parents, pregnant women and disabled persons to include poor adults without any children living at home. The researchers analyzed data from three states—Arizona, Maine and New York—that had expanded their Medicaid programs to childless adults (aged 20-64) between 2000 and 2005 and compared outcomes with four neighboring states without major Medicaid expansions—New Hampshire (for Maine); Pennsylvania (for New York); and Nevada and New Mexico (for Arizona).
The researchers looked at data from five years before and after each state’s expansion. They found that, compared to the states that did not expand Medicaid, the Medicaid expansions in the three states were associated with a mortality reduction of 6.1%, which corresponds to 2,840 deaths prevented per year for every 500,000 adults gaining Medicaid coverage. Mortality reductions were greatest among older adults, non-whites and residents of poorer counties. Expansions also were associated with increased Medicaid coverage, decreased uninsurance, decreased rates of deferring care due to costs and increased rates of “excellent” or “very good” self-reported health.

Use of Imaging as a Diagnostic Tool has Slowed
A new study published in Health Affairs finds that demand for new radiologists began declining in 2007 because of a decreased demand for imaging studies. The study authors found that use of magnetic resonance imaging (MRI) and computed tomography (CT) for patients in the United States slowed between 1 and 3 percent per year between 2006 and 2009, ending a decade of growth that had exceeded 6 percent annually. The authors say reasons for the decrease include the need for prior authorization for the tests, reduced reimbursement, increased cost sharing for patients and fears associated with radiation.

The current radiation crisis in Japan – while having no immediate impact on public health in the U.S. – has spurred domestic health officials to bolster their knowledge of what to do in a radiation emergency.
Today – from noon to 2 pm ET – the American Medical Association will host a free webinar on radiation emergencies.
Webinar speakers include Mary Selecky, secretary of health for the state of Washington — which has detected low levels of radiation from the Japan crisis, but no health threat so far — and Doran Christensen, associate director of the Department of Energy’s Radiation Emergency Assistance Center in Oak Ridge, Tenn.
Topics to be addressed include:
- Immediate and long-term public health responsibilities in a radiation emergency.
- Individual and group preparation for a radiation emergency.
- Different types of ionizing radiation and their medical implications.
- Diagnosis and treatment for radiation exposure.
Webinar participants will be able to ask questions of the speakers during the last half hour. The webinar will then be archived and available on the AMA website before the end of April.
A number of organizations and news outlets have ongoing resources to help understand what is unfolding in Japan.
- The Environmental Protection Agency is showing monitoring data for both air and water.
- The Centers for Disease Control and Prevention posts regular updates on the radiation emergency on its “What’s New” page.
- The New York Times has a dynamically updated topic page pulling together coverage of the situation in Japan.
- A series of hashtags on Twitter provide updates from news organizations and others on the ground in Japan (#fukushima, #radiation, #Japan)
