Public Health Campaign of the Month: Air Pollution and Heart Health

>>NewPublicHealth continues a new series to highlight some of the best public health education and outreach campaigns every month. Submit your ideas for Public Health Campaign of the Month to

In honor of American Heart Month, held each February, the U.S. Environmental Protection Agency (EPA) has created a new Public Service Announcement (PSA) to educate the public and health care providers about the risks of air pollution to the heart.

"Over more than four decades of EPA history, we've made tremendous progress cleaning up the air we breathe by using science to understand the harmful effects of air pollution," said EPA Administrator Gina McCarthy. “While EPA continues to fight for clean air, Americans can take further action to protect their heart health by following the advice in our new PSA.”

One of EPA’s commitments in the U.S. Surgeon General’s National Prevention Strategy is to educate health care professionals on the health effects of air pollution, including heart risks. This PSA supports the Million Hearts Initiative, launched by the U.S. Department of Health and Human Services in September 2011, to prevent one million heart attacks and strokes by 2017. 

Research has shown that air pollution can trigger heart attacks, stroke and worsen heart conditions, especially in people with heart disease—that’s one in three Americans. According to the EPA, very small particles are the pollutants of greatest concern for triggering health effects from exposure to air pollutants. These particles are found in transportation exhaust, haze, smoke, dust and sometimes even in air that looks clean. Particle pollution can also be found in the air at any time of the year. 

The new PSA advises people with heart disease to check the daily, color-coded Air Quality Index forecast. At code orange or higher, particle pollution can be harmful to people with heart disease. On bad air quality days, it is recommended to reschedule outdoor exercise or to exercise indoors instead, and avoid exercising near busy roads.

Air Quality Index forecasts for more than 400 cities are available on the forecast map through a free AirNow app for iPhone and Android phones, and through the free EnviroFlash e-mail service. To sign up, visit here and click on the “Apps” or “EnviroFlash” icons.

A Closer Look at California’s Drought


For now, California’s drought is reported to be the state’s worst in forty years, but climate scientists fear the weeks ahead could see it get even worse.

A map (right inset) produced by scientists at NASA’s Goddard Space Flight Center shows how dry California is compared to other states. Climatologists generate groundwater and soil moisture drought indicators each week, based on satellite data and other observations. This map, from January 13, shows the extent of the drought in California, with lighter colors indicating better soil saturation and darker colors indicating very dry land, compared to historical averages.

California’s drought has public health implications for both the state and the rest of the country for several reasons, including the potential for continued fires fueled by dry grass and trees, which pose risks such as fire injuries, smoke inhalation injuries and even death.

There could also be a produce shortage linked to the water crisis. The Associated Press has reported that city water managers in the state say the drought conditions may mean they have, on average, only about 5 percent of the needed water for consumers and farms in California. According to the U.S. Department of Agriculture,  California supplies half of the fruits and vegetables consumed in the United States. Reduced crop sizes can also drive up produce prices because of a lower–than-usual supply and the need for imports, which can be more expensive because of shipping and other fees.

HHS: 2.2M Enrolled for Coverage Under Affordable Care Act Through December
Despite a glitch-filled October 1 launch that saw only about 27,000 people enroll in the first month, by December 28 an estimated 2.2 million Americans had enrolled for health coverage available through the Affordable Care Act, according to the latest data from the U.S. Department of Health and Human Services. The state and federal online marketplaces enrolled nearly 1.8 million in December alone. Of the 2.2 million enrollees:

  • 54 percent are female and 46 percent are male
  • 30 percent are age 34 and under
  • 24 percent are between the ages of 18 and 34
  • 60 percent selected a Silver plan, while 20 percent selected a Bronze plan
  • 79 percent selected a plan with Financial Assistance

Task Force Recommends All Pregnant Women Be Screened for Gestational Diabetes
The U.S. Preventive Services Task Force is now recommending that all pregnant women be screened for gestational diabetes after 24 weeks of pregnancy. Gestational diabetes can increase the risk of pregnancy complications (such as preeclampsia) and labor complications, due to the baby growing larger than normal. Newborns are also at higher risk of low blood sugar levels after being exposed to the mother’s high blood sugar. Early diagnosis and treatment—lifestyle changes, blood sugar monitoring and insulin—can reduce the risks for both mother and child.  "The number of women who have gestational diabetes is rising, and gestational diabetes has effects not only on the mother, but also on the baby," said task force chairwoman Virginia Moyer, MD, vice president for maintenance of certification and quality at the American Board of Pediatrics. "We want to prevent adverse outcomes for both of them." Read more on maternal and infant health.

West Virginia Closer to Restoring Safer Tap Water After Chemical Leak
About 35,000 people in the area of Charleston, West Virginia, can now drink their tap water safely after it was declared usable again, according to West Virginia American Water. More than 300,000 customers were told their water was unsafe to drink and or use for washing after it was discovered last week that as much as 7,500 gallons of 4-methylcyclohexane methanol, or crude MCHM, from Freedom Industries had leaked into the Elk River. Officials estimate it will take a few more days before the entire system is once again safe. MCHM-tainted water can cause nausea, vomiting, dizziness, diarrhea, rashes and reddened skin; 231 people visited emergency departments with symptoms and 14 were admitted.

Oral Health as a Critical Public Health Challenge: Q&A with CDC’s Barbara Gooch


Late last year the Grand Rounds program of the U.S. Centers for Disease Control and Prevention (CDC) held a webinar on water fluoridation, a public health intervention that has been a priority in the United States for nearly seventy years.

Fluoridation, which has been shown to significantly reduce cavities in children, has been recognized by the CDC as one of 10 great public health achievements of the 20th century. Despite the benefits such as cost savings, however, CDC says there are ongoing challenges in promoting and expanding fluoridation.

NewPublicHealth recently spoke with Barbara Gooch, DMD, MPH, Associate Director for Science in the Division of Oral Health at CDC’s National Center for Chronic Disease Prevention and Health Promotion, about the challenges and benefits of water fluoridation and other emerging oral health improvement opportunities.

NewPublicHealth: What has been the historical impact of fluoridating water in the United States?

Dr. Barbara Gooch: All water generally contains fluoride, but usually at a level too low to prevent tooth decay, so community water fluoridation is a controlled adjustment of fluoride in a public water supply to an optimum concentration for the prevention of tooth decay.

That optimal concentration has historically been set at about 1 milligram (mg) of fluoride per liter of water, or 1 part per million. Fluoride was first introduced in the United States in Grand Rapids, Mich., in 1945. For cities that implemented community water fluoridation in the 1940s and 1950s, there was a dramatic reduction in tooth decay among children. Sometimes that reduction was greater than 50 percent. It has really been a major factor leading to the improvement in U.S. oral health.

When we compare the National Health and Nutrition Examination Survey done in the early 1970s with one conducted from 1999 to 2004, we found that the percentage of adolescents with one or more decayed teeth decreased from 90 percent in the early 1970s to 60 percent in the ’99-’04 National Survey. And while the number of teeth affected by tooth decay was an average of six in the 1970s survey, the instance was reduced to fewer than three in the later survey.

NPH: There are other sources of fluoride now, such as toothpaste. Is community water fluoridation still important?

Gooch: Current studies indicate that community water fluoridation increases the prevention of tooth decay by an additional 25 percent despite other sources. But the other very important factor about community water fluoridation is in order to receive its benefits, if you live in a fluoridated community. all you have to do is drink the tap water. And we can also show cost savings. One study estimates that for every dollar spent on community water fluoridation, you save about $38 in dental treatment costs.

E-cigarette Use Doubled for Middle, High School Students from 2011 to 2012
The use of e-cigarettes by U.S. middle and high school students more than doubled from 2011 to 2012, according to a new report from the U.S. Centers for Disease Control and Prevention (CDC). All told about 10 percent of the students used an e-cigarette in 2012; about 2.8 percent of students reported using one within the past 30 days; and a total of 1.78 million middle and high school students tried e-cigarettes in 2012. Curbing tobacco use early is critical because its addictive qualities can lead to a life time of use, which in turn can lead to a lifetime—and a shortened lifetime, at that—of severe health problems. “About 90 percent of all smokers begin smoking as teenagers,” said Tim McAfee, MD, MPH, director of the CDC Office on Smoking and Health. “We must keep our youth from experimenting or using any tobacco product. These dramatic increases suggest that developing strategies to prevent marketing, sales, and use of e-cigarettes among youth is critical.” Read more on tobacco.

U.S. Preterm Birth Rate at Lowest Point in 15 Years in 2012
The U.S. preterm birth rate was down to just 11.54 percent in 2012, its lowest point in 15 years and the sixth consecutive year the rate has fallen, according to a new preliminary date from the U.S. Centers for Disease Control and Prevention’s (CDC) National Center for Health Statistics. The pre-term rate reached a high of 12.8 percent in 2006. Jennifer L. Howse, MD, president of the March of Dimes, attributed the impressive drop to the efforts of the many state and local health departments; hospital partners; and physicians and nurses. “This sustained improvement over these past six consecutive years shows that when infant health becomes a priority, babies benefit,” she said, adding “We will continue to implement proven interventions and accelerate our investment in new research to prevent preterm birth so one day every baby will get a healthy start in life.” Infants who are born preterm (defined as 3 of more weeks before their due date) are at increased risk for health problems such as intellectual disabilities, cerebral palsy, respiratory problems, visual problems, hearing loss and digestive problems, according to the CDC.

Water Sanitation-based Outbreaks Still a Problem for Many Americans
Despite overall improvements, U.S. water sanitation is still a problem in some areas, with bacteria-laden drinking water leading to 1,040 illnesses, 85 hospitalizations and nine deaths in 17 states from 2009 to 2010, according to the U.S. Centers for Disease Control and Prevention. Legionella-tainted plumbing systems, untreated groundwater and problems with distribution systems were the leading causes of the 33 identified outbreaks. California, Florida, Georgia, Idaho, Illinois, Maine, Maryland, Minnesota, Missouri, Montana, Nevada, New York, Ohio, Pennsylvania, South Carolina, Utah and Vermont all reported drinking water-related outbreaks during that period. According to the CDC report, more research is needed into controlling Legionella, and more must be done to improve early detection and correction of problems with water-distribution systems.

World Water Day: Time for U.S. to Think About Water Quality Too


Today is World Water Day and in remarks at the State Department this morning, Secretary of State Hillary Clinton pointed out that the U.S. is not immune to the issue. “We are pursuing this not only because we care about it around the world; we care about it here at home. We’ve had increasing problems meeting our own needs in the Desert Southwest or managing floods in the East. No country anywhere, no matter how developed, is immune to the challenges that we face,” said Clinton.

In the U.S. water crises are more likely to be linked to emergencies such as weather disasters that can interrupt or contaminate water supplies:

Public Health Hits the Big Screen: A NewPublicHealth Q&A with Andre Blackman

file Andre Blackman, Fast Forward Health

Public health used to be something that happened behind the scenes and below the public consciousness. More and more, public health issues are making headlines and even coming to a theater near you, with movies like Contagion and The Interrupters. Now, public health even has a film festival to call its own.

Fast Forward Health is a film festival platform to showcase innovation in public and community health. The festival will take place November 1 at the West End Theater in Washington, DC. In advance of the festival, NewPublicHealth spoke with Andre Blackman, festival organizer, managing editor of Pulse+Signal, and director of digital communications and new media for the Mid-Atlantic American Heart Association.

NewPublicHealth: How did the idea for the Fast Forward Health film festival come about?

Andre Blackman: My interest has always been in public health innovation and new ideas and technology and thinking outside the box. One of the things that I got a little frustrated with after marinating in the public health world for a while and seeing the same thing over and over again as far as reports for issues or communities having the same tone each and every time – you know, a certain population is dying again, and they pull out the scrolling list of different diseases and conditions. I just felt there was way too much doom and gloom with public health.

Being in the social media world and being connected with individuals and projects here and across the world, I started seeing things that really excite me about the field – people standing up and making a difference. I really wanted to bring that into something that’s fun and interesting and really highlights and celebrates the innovation that’s happening. For the past year and a half I’ve been moving into the film and media world. I thought that would be a perfect intersection. I haven’t seen too many other initiatives like Fast Forward Health, celebrating these accomplishments in public health through film and video.

EPA and USDA Join Forces to Improve Rural Water Quality

The Environmental Protection Agency and the U.S. Department of Agriculture have announced a national partnership to use federal funds to train people for jobs in the water industry, including jobs related to safe drinking water and waste water. The industry currently has a shortage of trained staff, which could compromise public safety.

Depression Linked to Increased Stroke Risk in Women

A recent study in the journal Stroke found an increased risk of stroke in women diagnosed with depression, according to a news release. One reason for the increase may be that depression can keep people from taking care of health conditions that can lead to stroke, such as hypertension.

Female Smokers at Higher Risk for Heart Disease than Male Smokers

Women who smoke have a 25 percent higher risk of heart disease than men who smoke, according to a study in The Lancet.

Urine Test Can Help Predict Prostate Cancer, Aid Treatment Decisions

Researchers at the University of Michigan have developed a new urine test that may aid early detection of, and treatment decisions about, prostate cancer, according to a news release. The test, reported in the journal Science Translational Medicine, would be an add-on to current testing.

Preventive Measures Reduce Disease Transmission after Handling Pets in Public Settings

The Centers for Disease Control and Prevention released a report on measures – including hand washing – that can help prevent disease transmission after people handle pets in public settings, such as zoos and county fairs.

Time in the Shade: Protecting Workers from Heat Illnesses is the Law


The heat advisory released today from the National Weather Service, which notes that “from the southern Plains to the Atlantic coast, conditions will remain dangerously hot through at least the end of the work week,” comes with an additional advisory:

If you work or spend time outside in an area under a heat advisory or warning, take precautions to avoid heat-related stress or illness.”

The heat illness addition to the weather advisory is part of a campaign launched this season by the Occupational Safety and Health Administration in an effort to prevent the tens of heat-related deaths and thousands of illnesses that occurred last year among U.S. workers work who toil in the sun. Jobs requiring long stretches in the sun include farming, landscaping, construction, road repair, airport baggage handling and even car sales.

“It’s very important for workers and employers to take the steps necessary to stay safe in extreme heat," says David Michaels, Ph.D., M.P.H., Assistant Secretary of Labor for OSHA. "Drinking water often, taking breaks and limiting time in the heat are simple, effective ways to prevent heat illness.”

OSHA has developed heat illness materials in English and Spanish, as well as a curriculum to be used for workplace training. Workers fearful of losing a job or an hour’s pay may be reluctant to abide by heat illness protection recommendations – but employers have a legal duty to protect their workers from hot conditions. Last week the California Department of Industrial Relations shut down an agricultural company for failing to protect workers in temperatures that registered 105 degrees before noon.

Weigh In: Have there been heat-related employee deaths in your community?

Fracking: Upcoming Webinar Looks at Controversial Gas Extraction Process

In a recent blog post for the Public Health Law Network, Kathleen Dachille, director of the Network’s Eastern Region, writes that on the television show Battlestar Galactica, “frak” is a dirty word.

Nowadays, for some in the U.S., “fracking”, a natural gas extraction process that relies on blasting chemically treated water to remove the gas from rock, has become an unpleasant term as well.

Critics say the chemically treated water used for fracking (also known as hydrofracturing) can contaminate both drinking water and the environment and may also increase seismic activity and tree clearing that exposes rock, harms rural roads and can create chemical run-off in drinking wells. Fracking's proponents, on the other hand, contend that natural gas is considered a cleaner-burning energy source than oil or coal and is safer than nuclear energy.

Fracking has received increased attention recently, including a series of articles in the New York Times, a study by the Environmental Protection Agency, and an essay in the Huffington Post by actor Mark Ruffalo. It's also the subject of a recent documentary called Gasland.

To help explore the issues surrounding fracking, including recent legislation, health hazards, policies to protect the public’s health from risks, and the reactions of the public health community, the Public Health Law Network is hosting a webinar called “Fracking – Is It Just a Dirty Word?: Environmental and Public Health Considerations of Hydrofracturing, on Thursday May 19th from 1 p.m. to 2 p.m. (ET). Webinar presenters include Josh Fox, Gasland filmmaker, and Conrad D. Volz, Dr.P.H., M.P.H., assistant professor of environmental & occupational health at the University of Pittsburgh.

The webinar is part of the free Public Health Law Webinar Series, sponsored by the American Society of Law, Medicine & Ethics; the Public Health Law Association; the Public Health Law Network; and the Public Health Law Research Program.

Register for the webinar by 2 p.m. (ET) on Tuesday May 17. Information will be sent to those registered prior to the webinar.
