When it comes to being healthy, what happens outside the doctor’s office can be just as important as what happens in an examination room—sometimes even more. The environment you call home plays a tremendous role in your health.
But which types of environments and communities will help you stay the healthiest? A series of videos from the National Institutes of Health’s Office of Behavioral and Social Sciences Research highlights ongoing federal research into how to create communities where healthy choices are the easy choices.
Dr. David R. Williams: The Social Factors of Health
Williams, MPH, PhD, is a social scientist at Harvard University who believes that where we live, learn, work and play have more to do with our health than doctor visits. His work focuses on the opportunities and barriers that affect healthy living.
Dr. Ana Diez-Roux: The Science of Environmental Factors of Health
Diez-Roux, MD, PhD, is an epidemiologist at the University of Michigan. Her work looks at the social determinants that influence our health.
Dr. David Schwebel: The Science of Child Safety
Schwebel, PhD, is a Professor of Psychology and Associate Dean for Research and the Sciences at the University of Alabama at Birmingham. His work applies basic psychological and behavioral principles to the real-life problem of preventing children’s injuries.
Concerned by reports that volunteers and New Jersey residents are frequently unaware of environmental dangers when cleaning up homes and communities, the New Jersey Department of Health released an advisory earlier this week with advice on staying safe while scrubbing and rehabbing. Mold and materials containing asbestos and lead-based paint are examples of potential hazards in storm-damaged buildings and the advisory urged those tackling the heavy jobs to wear protective equipment appropriate for the work they are doing such as waterproof boots, gloves, goggles, and face masks.
"Homeowners doing cleanup work and the volunteers assisting them are critical assets in New Jersey's recovery efforts, but making sure they protect themselves is equally important," said New Jersey Health Commissioner Mary O'Dowd.
NewPublicHeatlh recently spoke about Hurricane Sandy clean-up safety with Donna Leusner, director of communications for the New Jersey Department of Health; Tina Tan, MD, state epidemiologist and assistant commissioner for epidemiology, environmental and occupational health and Joe Eldridge, director of New Jersey’s Consumer, Environmental and Occupational Health Service.
NewPublicHealth: What kind of environmental concerns specifically are there for those cleaning up the community after the storm?
Dr. Tan: There are concerns about individuals coming into contact with contaminated materials, whether contaminated with chemicals or infectious agents—residuals from flood waters as well as the general debris that might be around. We encourage individuals to take the appropriate precautions to try to avoid any sort of injuries or potential illnesses that could result from contact with these contaminated materials.
NPH: Are people aware of the critical basic information for safe cleanup, such as getting a tetanus shot if they’re injured during the cleanup in such terrible conditions?
Among the impacts of the East Coast’s Hurricane Sandy have been tens of thousands of uprooted trees, contaminated water and tons of compromised food. A recent article in the Journal of Environmental Health Natural recommends that environmental health become an integral part of emergency preparedness and that community stakeholders take a role in merging the two.
David Dyjack, DrPH, associate executive director of the National Association of County and City Health Officials, and a co-author of the study, spoke with NewPublicHealth about building momentum to include environmental health in disaster emergency preparedness.
NewPublicHealth: What does the article address?
David Dyjack: The article is the first step in a series of research steps looking at how best to integrate environmental health and emergency preparedness so that communities are more resilient and take greater responsibility for their own health and safety in the event of an environmental disaster.
NPH: What is distinct about environmental health emergency preparedness?
In a new interview with Ramona Trovato, Deputy Assistant Administrator of the Environmental Protection Agency (EPA), NewPublicHealth continues its conversation series about the National Prevention Strategy. The strategy was released last year by Surgeon General Regina Benjamin, MD, MBA, to help create a healthier and more fit nation.
Earlier this year the Surgeon General’s office released the Strategy’s National Action Plan, designed to show how the 17 Federal Agencies charged with advancing the National Prevention Strategy are implementing its vital components. The EPA has several partner initiatives critical to the health of the nation, which include:
- Partnership for Sustainable Communities: The EPA is a partner, together with the Department of Transportation and the Department of Housing and Urban Development, in this partnership to help communities improve access to affordable housing and transportation while protecting the environment, all critical aspects of healthy living.
- Green Ribbon Schools: EPA is a partner with the Department of Education and other agencies for this recognition award that encourages state education agencies and schools to recognize the links between education, health, and the environment, and to make all three of these areas a priority.
- Safe routes to school: Agencies including HHS, EPA and the Department of Transportation support efforts to improve the ability of students to walk and bicycle to school safely.
- Task Force on Environmental Health Risks and Safety Risks to Children: This multi-agency task force, which includes the EPA, recommends strategies for protecting children's health and safety, including specific priorities around asthma, unintentional injuries, lead poisoning, cancer, and environmental health in schools.
- Aging Initiative: This EPA initiative aims to prioritize environmental health hazards that affect older persons, focus on “smart growth” principals to support active aging, and examine the environmental impact of an aging population, and encourage civic involvement among older persons in their communities to reduce hazards.
Ramona Trovato shared with us EPA’s long history of health promotion and its current efforts to help improve population health as a member agency of the National Prevention Council.
NewPublicHealh: How does the Environmental Protection Agency (EPA) align itself with the National Prevention Strategy?
Ramona Trovato: The EPA is really pleased to be part of the National Prevention Council and the National Prevention Strategy. We firmly believe in preventing ill health and in promoting wellness, and it’s something that matters to us in all the work that we do. We have very successfully partnered with Department of Health and Human Services in the past and with a number of other federal agencies including the Consumer Product Safety Commission, the Department of Transportation and the Department of Housing and Urban Development to benefit the public’s health.

Study Recommends Treatment for Mini Strokes
A transient ischemic attack or a “mini stroke,” can lead to serious disability, but is often thought of as too mild to treat, according to a study in the American Heart Association journal Stroke. Among the 499 patients studied, 15 percent had at least minor disability 90 days after their original mini stroke. Computed tomography (CT) scans showed some mini stroke patients had narrowed blood vessels in the brain, and others reported ongoing or worsening symptoms. Those patients were more than twice as likely to have disability at 90 days. The researchers say imaging should be done on all mini stroke patients to determine whether treatment is needed.

Wildfire Smoke Linked to Low Birth Weights
Pregnant women exposed to wildfire smoke during Southern California’s 2003 fire season had babies with lower birth weights when compared to babies not exposed to the smoke, according to researchers from the University of California, Berkeley School of Public Health. The researchers say the finding is important because climate change is expected to increase the number of wildfires in the United States. The study was published in Environmental Health Perspectives.

Violent Video Games Linked to Reckless Driving in Teens
A new study in the journal Psychology of Popular Media Culture finds that teens who play video games that emphasize risk and violence may be more likely to take risks when driving. Read more on violence.
IDSA Issues New Strep Throat Guidelines
Most sore throats are the result of a virus—not the bacteria that causes strep throat—so should not be treated with antibiotics, according to new guidelines from the Infectious Diseases Society of America (IDSA) appearing in Clinical Infectious Diseases. Strep throat, caused by streptococcus bacteria, should be treated with penicillin or amoxicillin, assuming the patient is not allergic. The IDSA also recommends against removing the tonsils of children who suffer repeated cases of strep throat. Read more on infectious disease.
USDA Grants to Provide Housing for Farm Workers in Rural Communities
The U.S. Department of Agriculture (USDA) has announced new grants to develop farm labor housing. “These grants will help communities submit quality applications to increase their chances of getting funding to build much-needed affordable housing for farm workers,” said Agriculture Secretary Tom Vilsack. “Increasing the supply of affordable housing in rural communities not only helps the residents, it helps the entire community.” You can go here to read more about submitting applications.

Climate Change Could Lead to Increase in Avian Flu
A new report in Biology Letters by researchers from the University of Michigan says that climate change—among all its other many effects—could also increase the rate of avian influenza in wild birds. They utilized a mathematical model to show how climate change could alter the interactions between birds and crabs in Delaware Bay, increasing the rate of infection and expanding from there to other areas. “We’re not suggesting that our findings necessarily indicate an increased risk to human health,” said Pejman Rohani, a professor of ecology and evolutionary biology, a professor of complex systems and a professor of epidemiology at the School of Public Health. “But every single pandemic influenza virus that has been studied has included gene segments from avian influenza viruses. So from that perspective, understanding avian influenza transmission in its natural reservoir is, in itself, very important.” Read more on environment.
Environmental issues are consistently a topic of hot debate. A new study reveals that how we talk about these issues could have a big impact on whether people feel compelled to act on them. According to new research led by two awardees of the Robert Wood Johnson Foundation Investigator Awards in Health Policy Research, Matthew C. Nisbet, PhD, MS, and Edward W. Maibach, PhD, MPH, talking about the environmental consequences of climate change may not convince the unconvinced—while talking about the public health consequences might have a better chance.
As the American University and George Mason University professors write in a newly published study in the journal Climatic Change Letters, “Results show that across audience segments, the public health focus was the most likely to elicit emotional reactions consistent with support for climate change mitigation and adaptation.” The study was co-authored with Teresa Myers and Anthony Leiserowitz.
We caught up with Matthew Nisbet to get his take on the latest findings, and how the public health field can do a better job of framing issues in a way that motivates action.
NPH: What is message framing?
Matthew Nisbet: When you frame something as a communicator or as a journalist or as an expert, what you do is you emphasize one dimension of a complex issue over another, calling attention to certain considerations and certain arguments more so than other arguments. In the process, what you do is you communicate why an issue may or may not be a problem, who or what is responsible for that problem and then what should be done. One of the common misunderstandings about framing is that there can be something such as unframed information. Every act of communication, whether intentional or not, involves some type of framing.
NPH: Why is framing so important in communicating about public health issues?
Salmonella Deaths Linked to Cantaloupes
Two deaths and approximately 150 cases of salmonella have been linked to cantaloupe in Indiana, Kentucky and Minnesota. Health officials are encouraging consumers to immediately discard any melons purchased from those three states, according to Reuters. Salmonella can cause severe diarrhea, fever and abdominal pain. It is especially dangerous for children, the elderly and people with weakened immune systems. Read more on food safety.
Teens Who Expect Early Deaths More Likely to Take Dangerous Risks
Teens who predict they have a 50 percent or less chance of living to the age of 35 were more likely than they peers to engage in risk-taking behavior, according to a new study published in the August 1 issue of PLOS ONE. The study compared data collected on 19,000 adolescents in 1994-95 to data collected on the same group approximately 14 years later. Researchers also found the teens were more likely to attempt suicide and abuse alcohol and drugs. “The new research extends previous work by the same group that found expectations of premature death can predict future socioeconomic status” and demonstrates the value in early screening to help predict—and stop—later harmful behaviors, according to a news release.

Antimicrobial Products Identified in Minnesota Waterways
Chemicals found in personal care products—antimicrobial soaps, disinfectants and sanitizers—have been identified in high concentrations in bodies of freshwater in Minnesota. The study was conducted by Arizona State University researchers in conjunction with federal partners. They looked specifically for triclosan and triclocarban, two chemicals that can stay in the environment for decades. The study “shows natural degradation processes to be too slow to counter the continuous environmental release of these endocrine disrupting chemicals,” said Rolf Halden, director of Environmental Security at the Biodesign Institute and professor in the Ira A. Fulton School of Sustainable Engineering and the Built Environment. Read more on the environment.
Supreme Court Decision Due Today on Affordable Care Act
The Supreme Court is expected to announce its decision today on the constitutionality of the Affordable Care Act. Follow NewPublicHealth for information on how the decision impacts public health.
Last year, America’s beaches saw the third-highest number of closing and advisory days in more than two decades, according to the 22nd annual beach water quality report by the Natural Resources Defense Council, which says that U.S. beaches continue to suffer from storm water runoff and sewage pollution.
The group recommends establishing better beach water quality standards and the report gives out ratings for 200 U.S. beaches based on water quality and best practices for testing and public notices. Read more on environmental health.
The Food and Drug Administration has approved the drug Belviq (lorcaserin hydrochloride), as an addition to a reduced-calorie diet and exercise, for chronic weight management.
The drug is approved for use in adults with a body mass index (BMI) of 30 or greater (obese), or adults with a BMI of 27 or greater (overweight) and who have at least one weight-related condition such as high blood pressure (hypertension), type 2 diabetes or high cholesterol (dyslipidemia). Belviq works by activating a serotonin receptor in the brain, which may help a person eat less and feel full after eating smaller amounts of food. Treatment with Belviq for up to one year resulted in average weight loss ranging from 3 percent to 3.7 percent.
The American Red Cross says its blood supply has reached emergency levels because 50,000 fewer donations than expected were received in June. The shortfall is about half of what the Red Cross had on hand at this time last year. Shortages can result in postponed surgeries, according to the Red Cross, which estimates that someone in the nation needs a blood transfusion every two seconds.
The shortage may have been the result of warmer weather starting earlier this year, which may have kept some regular donors from taking time to donate blood or platelets.
Donors must be 17 (16 with parental permission in some states), weigh at least 110 pounds, and be in general good health. Donors must have a driver’s license, blood donor card or two other forms of ID at check-in. To find a local donor site and make a donation, call the Red Cross at 800 733-2767 or sign up online.

A study that reviewed cancer incidence records and was published in the Journal of Clinical Oncology finds although the overall lung cancer rate in the United States has been declining, lung cancer deaths among baby boomer women living in some southern and Midwestern states have been rising. The authors link the increase to cigarette advertising targeted at girls and women women in the 1960s and 1970s. Read more on cancer.
A study in the journal Circulation finds that young, healthy adults exposed under experimental conditions to ozone for two hours developed heart changes that could put them at risk for heart attacks.
Study participants showed evidence of vascular inflammation, a potential reduced ability to dissolve artery-blocking blood clots, and changes in the body’s processes that control the heart’s rhythm. The changes were temporary and reversible in the young adults in the study, but show the potential dangers of prolonged exposure to ozone. Read more on environmental health.
A ballot initiative to increase California's cigarette tax by $1 per pack was defeated by about half a percent, the closest vote in California ballot initiative history. According to the Campaign for Tobacco Free Kids, if this initiative had passed, it would have prevented 228,700 California children from becoming smokers. Read more on tobacco.
