Living in a Food Desert: How Lack of Access to Healthy Foods Can Affect Public Health

Need to run to the grocery store? For some of us, this is relatively easy because we probably live fairly close to one. For others, a trip to a grocery store represents a significant transportation challenge. In the United States, “food deserts”, neighborhoods and communities that have limited access to affordable and nutritious foods, tend to be located in urban and rural low-income neighborhoods. People who live in these areas are less likely to have access to supermarkets or grocery stores that provide healthy choices for food. With limited or no access to food retailers or supermarkets that stock fresh produce, low-fat dairy, whole grains, and other healthy foods, these populations may be more likely to suffer from high rates of diabetes, cardiovascular disease, and obesity.

The Public Health Effect of Food Deserts: Workshop Summary discusses the public health effects—including the prevalence of obesity and the incidence of chronic diseases—of food deserts. This book offers insight on the extent of food deserts, their impact on individual behaviors and health outcomes in various populations, and effective ways to increase the availability of fruits and vegetables and to improve the food environment.

One serious health consequence of living in food deserts is, ironically, obesity. Without ready access to nutritious foods, people living in food deserts often have diets that are high in calories but low in nutritional value. To address this particular public health concern, the Institute of Medicine has published a number of reports that examine how we can roll back the obesity epidemic in the United States.

Bridging the Evidence Gap in Obesity Prevention: A Framework to Inform Decision Making examines obesity as a societal problem that affects whole populations, like those living in food deserts. This book features a practical, action-oriented framework to support the use of evidence in decision-making about obesity prevention policies and programs and sets a course for the development of new and relevant research.

The books mentioned above and others from the Institute of Medicine provide information and guidance for decision-makers to respond to the challenges of food deserts and their impact on our society.

DNA Testing: From the Doctor’s Office to the Drugstore

The Human Genome Project, completed in 2003, identified the genes that make up human DNA. Major advances in genomic technologies in the early 21st century have helped to increase dramatically the number of genes identified as playing a role in a variety of common disorders. Genetic or genomic testing can be used to guide medical decision-making and treatment, ranging from personalized drug therapy to assessing an individual’s risk of developing common chronic diseases.

New reports from the Institute of Medicine discuss various possibilities for the future and potential issues that could arise from our ever-expanding knowledge of our genetic makeup. The Value of Genetic and Genomic Technologies: Workshop Summary explores the concept of value in regards to genomics and genetics and how that concept affects the ways decisions are made about using tests and technologies. This book brings together diverse perspectives on the value of genetic testing and discusses its use in clinical practice.

Advances in our understanding of genomics, combined with significant reductions in the cost of genetic tests, have spawned new business models in which companies market genetic tests and personalized genetic profiles directly to consumers. For example, it is now possible to purchase a home DNA paternity test at many pharmacies in the United States. Special DNA test kits allow anyone to trace their ancestry. Direct-to-Consumer Genetic Testing: Summary of a Workshop discusses the scientific and ethical foundations for commercial genetic testing, personal and social issues, research and medical issues, and the impact on health care and public health.

These books and others from the Institute of Medicine explore the possibilities and directions for the future for both researchers and private industry.

The Ripple Effect of the Oil Spill: Prevention, Human Health, and More

Tuesday the presidential panel investigating the Gulf of Mexico oil spill released its final report, analyzing problems that led to the incident and making recommendations for new regulations to prevent a similar disaster. The National Research Council, National Academy of Engineering, and the Institute of Medicine have produced a number of reports that discuss causes of the oil spill and its effects on human health.

Interim Report on Causes of the Deepwater Horizon Oil Rig Blowout and Ways to Prevent Such Events examines the probable causes of the Deepwater Horizon explosion, fire, and oil spill and identifies measures for preventing similar harm in the future. The book addresses the performance of technologies and practices involved in the probable causes of the Macondo well blowout and explosion on the Deepwater Horizon. It also explores industry best practices and standards, and identifies and recommends available technologies and measures that can ensure a higher level of safety in deepwater exploratory drilling and well completion.

New Planets, New Possibilities in Space Research

On Monday a team of NASA astronomers announced the discovery of the first rocky planet orbiting a star outside our solar system. The discovery of the planet, named Kepler-10b, was the result of data collected by the Kepler spacecraft, launched by NASA in March 2009.

Remember when grade school astronomy consisted mainly of knowing the names of the nine planets in order from the sun? We have come a long way from the astronomy taught to us even 10 years ago. In recent decades, significant progress in the fields of astronomy and astrophysics has brought about a revolution in understanding of the origins and nature of our universe. Hundreds of planets of startling diversity have been discovered orbiting distant suns. Black holes, once viewed as exotic theoretical possibilities, are now known to be present at the center of most galaxies, including our own. Precision measurements of the primordial radiation left by the big bang have enabled astronomers to determine the age, size, and shape of the universe. Recent discoveries, powerful new ways to observe the universe, and bold new ideas to understand it have created unprecedented scientific opportunities.

So how can we make the most of these opportunities to better understand our universe? New Worlds, New Horizons in Astronomy and Astrophysics, a new book from the National Research Council, outlines a plan for ground- and space- based astronomy and astrophysics for the coming decade. This book, based on comprehensive input from the astronomy and astrophysics community, presents exciting yet realistic recommendations.

A companion volume, Panel Reports–New Worlds, New Horizons in Astronomy and Astrophysics features a collection of reports on various sub-areas of astronomy and astrophysics. Each of these reports played an important role in setting overall priorities.

These titles and others can guide future research and decision making.

Understanding Baby Boomers and the Medicare Crunch

The year 2011 marks a milestone for the Baby Boom generation, as they begin turning 65. Boomers will be qualifying for Medicare at a rate of one every eight seconds; a record 2.8 million will qualify in 2011. In all, the government expects 76 million Boomers will age on to Medicare. The rapid escalation of beneficiaries along with health care cost increases that are outpacing inflation present a huge challenge to the Medicare system.

A recent report from the National Research Council, Improving Health Care Cost Projections for the Medicare Population: Summary of a Workshop, focuses on areas of research needed to improve health care cost projections for the Medicare population and on the strengths and weaknesses of competing frameworks for projecting health care expenditures for the elderly.

Another recently released report, Accounting for Health and Health Care: Approaches to Measuring the Sources and Costs of Their Improvement, provides guidance about what data are needed to measure the output produced by the medical care sector. Without this kind of information it is impossible to credibly assess whether the nation spends too much or too little on medical care relative to, say, public health measures, and, perhaps more important, whether we purchase something close to the right mix of medical care goods and services for a given level of resources expended.

These books and others can provide information and direction for health care cost research and decision making.

Resources to Inform our Energy Future

As some of us prepare for holiday travel, it is fairly noticeable that gasoline prices have risen in recent weeks. U.S. prices currently range from $2.68/gallon in Denver to $3.29/gallon in San Francisco. According to data from the U.S. Energy Information Administration, the United States leads the world in petroleum consumption. As consumers look for ways to reduce their fuel costs by combining errands and other means, it’s a good time to look again at our energy prospects.

America’s Energy Future: Technology and Transformation assesses the status of energy-supply and end-use technologies in the United States, both at present and over the next two to three decades. It is intended to inform the development of comprehensive/sustainable energy policies by our nation’s decision makers and to provide the technical underpinnings for more detailed explorations of key energy-policy options. This book analyzes the potential of a wide range of technologies for generation, distribution, and conservation of energy.

Real Prospects for Energy Efficiency in the United States, part of the America’s Energy Future series, examines the potential for reducing energy demand through improving efficiency by using existing technologies, technologies developed but not yet widely utilized, and prospective technologies. According to this study, energy efficiency technologies that exist today or that are likely to be developed in the near future could save considerable money as well as energy. Fully adopting these technologies could lower projected U.S. energy use 17 percent to 20 percent by 2020, and 25 percent to 31 percent by 2030. This book evaluates technologies based on their estimated times to initial commercial deployment, and provides an analysis of costs, barriers, and research needs.

These titles, as well as others in the America’s Energy Future series, form a picture of our present situation and our choices for the future. The National Research Council has recently published a number of books on energy, all of which can inform and guide debate and decision-making.

Science for Climate Change Decision-Making

Earlier this month the World Meteorological Organization announced that the year 2010 is almost certain to rank among the top three warmest years since the beginning of instrumental climate records in 1850. WMO’s data show that 2001-2010 is the warmest ten-year period on record. In November WMO reported that concentrations of the main greenhouse gases have reached their highest levels recorded since pre-industrial times.

This year, the National Research council produced a number of studies that directly address climate change and its effects. Advancing the Science of Climate Change reviews the current scientific evidence regarding climate change and examines the status of the nation’s scientific research efforts. It also describes the critical role that climate change science, broadly defined, can play in developing knowledge and tools to assist decision makers as they act to respond to climate change. The report explores seven cross-cutting research themes that should be included in the nation’s climate change research enterprise, and recommends a number of actions to advance the science of climate change—a science that includes and increasingly integrates across the physical, biological, social, health, and engineering sciences.

Advice on prudent short-term actions and long-term strategies to deal with the effects of climate change can be found in the companion reports Limiting the Magnitude of Future Climate Change, Adapting to the Impacts of Climate Change, and Informing an Effective Response to Climate Change.These titles and others from the Board on Atmospheric Sciences and Climate provide information and direction for research and decision making.

The performance of U.S. students in science has been in the news this week, as we ranked 23rd in an international standardized assessment given to 15 year-olds in schools. We asked Martin Storksdieck, the director of the National Research Council Board on Science Education, for his perspective.

On December 7th the results of the largest international assessment of student performance in reading, math and science were released. The Programme for International Student Assessment, known as PISA, is conducted under the coordination of the Organization for Economic Cooperation and Development (OECD), and is supported by national organizations in 65 countries. The ranking of countries in PISA, based on the scholastic performance of a statistical sample of their 15-year olds on this test, can be a matter of much national pride or disappointment, may lead to questions about its validity and fairness, or might get ignored entirely. However countries may respond to this huge international effort, or whether one agrees entirely on the appropriateness of the assessment being used, PISA does elicit questions about why students in some countries do so much better than students in other countries, and ultimately what the factors are that make for effective education.

While research on reasons for country differences exist, there is little agreement on how much one country can learn from another. However, research on what contributes to effective science teaching and learning that is ultimately reflected in sophisticated and appropriate tests of student performance has been compiled and critically assessed in a variety of recent reports from the National Research Council. In Taking Science to School, America’s Lab Report and Learning Science in Informal Environments, various expert committees developed frameworks and criteria for effective science learning, based on existing evidence. These reports contain much of the information that can guide best practice in science education, and, if applied widely in and out of classrooms, may help improve student performance on tests like PISA.

These books and other titles from the National Research Council can inform discussion and provide guidance to promote science education.

The Global HIV/AIDS Crisis: Resources to Inform Decision Making

In 2008, more than 33 million people across the globe had HIV/AIDS, 67 percent of whom were in Africa. In addition, more than 90 percent of the 2.7 million new infections reported that year occurred in Africa, and only half of Africans who should have received antiretroviral therapy (ART) according to World Health Organization guidelines then in place were treated. By 2020, the number of infected people in Africa is estimated to grow to over 30 million, with just 7 million of the approximately 12 million who should be treated under current guidelines likely able to receive ART, according to a new report released by the Institute of Medicine.

Preparing for the Future of HIV/AIDS in Africa: A Shared Responsibility says that the number of people infected with HIV/AIDS in sub-Saharan Africa is projected to far outstrip available resources for treatment by the end of the decade, forcing African nations to make difficult choices about how to allocate inadequate supplies of lifesaving ART. The report calls for a renewed emphasis on reducing the rate of new infections, promoting more efficient models of care, and encouraging shared responsibility between African nations and the U.S. for treatment and prevention efforts, which could greatly improve prospects for the future.

The global AIDS pandemic calls for action beyond Africa, too. There are many countries in Eastern Europe, the Commonwealth of Independent States, and Asia where the sharing of contaminated injecting equipment is the primary mode of HIV transmission. In some cases, HIV is spreading rapidly from injecting drug users to their partners through sexual transmission, and from injecting drug users and their partners to newborns. Preventing HIV Infection among Injecting Drug Users in High Risk Countries: An Assessment of the Evidence finds that several key approaches can reduce HIV related risk behavior among injecting drug users. The report urges high-risk transitional and developing countries to take immediate steps to make these techniques widely available.

These reports and others from the Institute of Medicine can inform and guide discussion of the HIV/AIDS crisis both internationally and here in the United States, where according to the Centers for Disease Control there were 56,000 newly infected Americans and 15,000 AIDS-related deaths in 2008.

	Preparing for the Future of HIV/AIDS in Africa: A Shared Responsibility HIV/AIDS is a catastrophe globally but nowhere more so than in sub-Saharan Africa, which in 2008 accounted for 67 percent of cases worldwide and 91 percent of new infections. The IOM recommends that the United States and African nations move toward a strategy…
