Overweight Teens Should Start Healthy Eating by Cutting Down on Salt
Overweight or obese teenagers who eat lots of salty foods shows signs of faster cell aging, according to research presented at the American Heart Association’s Epidemiology & Prevention/Nutrition, Physical Activity & Metabolism Scientific Sessions 2014. Previous research found that protective ends on chromosomes (telomeres) naturally shorten with age, but the process is accelerated by smoking, lack of physical activity and high body fat. This study is the first to examine the impact of sodium intake on telomere length.
In the study, 766 people ages 14-18 were divided into the lowest or highest half of reported sodium intake. Low-intake teens consumed an average 2,388 mg/day, compared with 4,142 mg/day in the high-intake group. Both groups consumed far more than the 1,500 mg/day maximum (about 2/3 teaspoon of salt) recommended by the American Heart Association. After adjusting for several factors that influence telomere length, researchers found that in overweight/obese teens, telomeres were significantly shorter with high-sodium intake. In normal weight teens, telomeres were not significantly different with high-sodium intake.
“Even in these relatively healthy young people, we can already see the effect of high sodium intake, suggesting that high sodium intake and obesity may act synergistically to accelerate cellular aging,” said Haidong Zhu, MD, PhD, lead author of the study and assistant professor of pediatrics at Medical College of Georgia, Georgia Regents University in Augusta, Ga. “Lowering sodium intake may be an easier first step than losing weight for overweight young people who want to lower their risk of heart disease. The majority of sodium in the diet comes from processed foods, so parents can help by cooking fresh meals more often and by offering fresh fruit rather than potato chips for a snack.” Read more on heart health.
DOT Awards Grants to Improve Transportation for American Indian and Alaska Native Tribes
The U.S. Department of Transportation is awarding $5 million to 42 American Indian and Alaska Native tribes in 19 states for projects to improve transit service, in addition to $25 million in funds announced recently to help improve public transit service on rural tribal lands and better connect tribal members and other residents with jobs, education, and other opportunities.
“We fully recognize that residents on tribal lands and in surrounding communities often face significant transportation challenges, as many cannot afford to own a vehicle, or fill the tank, and yet must travel long distances to reach basic services,” said Federal Transit Administration head Therese McMillan. “We want to ensure that everyone who needs a ride to earn a paycheck, attend school, see the doctor, or buy groceries has that opportunity.” Read more on transportation.
Health Providers Should Prescribe Sleep for People with Metabolic Disorders
A new study in The Lancet Diabetes & Endocrinology finds that insufficient or disturbed sleep is associated with metabolic disorders such as type 2 diabetes and obesity, and addressing poor quality sleep should be a target for the prevention—and even treatment—of the disorders. According to the study authors, addressing some types of sleep disturbance—such as sleep apnea—may have a directly beneficial effect on patients' metabolic health, but a far more common problem is people simply not getting enough sleep, particularly due to the increased use of devices such as tablets and online games. The authors say that early studies are starting to provide evidence that there is a direct causal link between loss of sleep and the body's ability to metabolize glucose, control food intake, and maintain its energy balance.

Some Will Be Able to Enroll After March 31 Affordable Care Act Deadline
Some people will be able to enroll for coverage under the Affordable Care Act after the official enrollment deadline of March 31, according to new guidelines expected to be issued by the Obama administration. The new guidelines would allow people had previously tried to enroll by were prevented by systems problems such as technical difficulties, according to Reuters. "Open enrollment ends March 31. We are preparing for a surge in enrollment, and if consumers are in line on the 31st and can't finish, we won't shut the door on them. To be clear, if you don't have health insurance and do not start to sign up by the deadline, you can't get coverage again until next year," said U.S. Department of Health and Human Services spokeswoman Joanne Peters in a statement.

Study: Alcohol-Related Vehicle Crashes Greatly Underreported
Alcohol is a far greater factor in U.S. motor vehicle deaths than has been reported, according to a new study in the Journal of Studies on Alcohol and Drugs. Using Fatality Analysis Reporting System (FARS) data from the U.S. National Highway Traffic Safety Administration, researchers determined that in the decade from 1999 to 2009 while only a little more than 3 percent of the death certificates for traffic deaths included alcohol as a contributing cause, about 21 percent of the deaths were legally drunk. Approximately 450,000 Americans were killed in traffic crashes during the period. The time that it takes coroners to take and process blood alcohol tests could be a reason for the underreported figures. Ralph Hingson, Sc.D., of the U.S. National Institute on Alcohol Abuse and Alcoholism, said the vast discrepancy demonstrates the need for more reliable data. "We need to have a handle on what's contributing to the leading cause of death among young people," he said in a release. "You want to know how big the problem is, and if we can track it. Is it going up, or going down? And what policy measures are working?" Read more on alcohol.
NIH Identifies Genetic Markers Tied to Stroke, Cardiovascular Disease
Researchers and the National Institutes of Health have identified a genetic variant linked to increased risk for stroke, as well as a metabolic pathway tied to several common diseases, which taken together could improve how doctors identify and treat major diseases. “Our findings have the potential to identify new targets in the prevention and treatment of stroke, cardiovascular disease and many other common diseases,” said Stephen R. Williams, PhD, a postdoctoral fellow at the University of Virginia Cardiovascular Research Center and the University of Virginia Center for Public Health Genomics, Charlottesville. The genetic markers were found through the analysis of nearly 5,000 genomes. The results were published in the journal PLoS Genetics. About 600,000 Americans die of heart disease each year—one in every four deaths—and stroke is the fourth-leading cause of death in the United States. Read more on heart health.
Study: School Hearing Tests Cannot Detect Adolescent High-Frequency Hearing Loss
School-administered hearing tests cannot detect the sort of adolescent high-frequency hearing loss associated with exposure to loud noises, according to a new study in the Journal of Medical Screening. Researchers at Penn State College of Medicine compared the results for 282 11th graders of a special hearing screening designed to detect noise-related high-frequency hearing loss with the results of the standard Pennsylvania school hearing test. Each tests for the ability to hear a tone at a specific loudness. "More participants failed the initial screening than we predicted," said study author Deepa Sekhar, assistant professor of pediatrics, in a release, "Even with the effort and care put in by school nurses across the state, the current Pennsylvania school screen just isn't designed to detect high-frequency hearing loss in adolescents," adding "The results of this study have the potential to reach schools across the nation, as many use screens similar to those used in Pennsylvania schools."

HUD Gives $1.8B to Support 3,100 Public Housing Authorities
The U.S. Department of Housing and Urban Development (HUD) has awarded almost $1.8 billion to approximately 3,100 public housing authorities across all 50 states, as well as the District of Columbia, Guam, Puerto Rico and the U.S. Virgin Islands. The grants, which come through HUD’s Capital Fund Program, will go toward building, repairing, renovating and modernizing public housing, from large scale improvements such as replacing roofs or smaller tasks such as energy-efficient upgrades. “This funding is critically important to public housing agencies as they work to provide the best housing possible for their residents,” said HUD Secretary Shaun Donovan. There are 1.1 million public housing units in the United States. Read more on housing.
New Heart Health Guidelines Would Increase Adults Eligible for Statins to 12.8M
New guidelines from the American College of Cardiology and the American Heart Association (ACC–AHA) for the treatment of cholesterol would increase the number of adults who would be eligible for statin therapy by 12.8 million, according to a new study in the New England Journal of Medicine. Roughly half of the U.S. population between 40 and 75 years of age—or 56 million people—would be eligible. Most of the increase would be among older adults without cardiovascular disease.

Teens who Leave Gangs Still Face Consequences as Adults
A new study in the American Journal of Public Health finds that joining a gang during teen years has significant consequences in adulthood beyond criminal behavior, even after a person leaves the gang.
The study authors followed 808 fifth-grade students from 18 elementary schools in high-crime neighborhoods in Seattle, beginning in 1985. Participants were interviewed every year until the age of 18, then every three years until the age of 33.
Researchers used 23 risk factors, including poverty and associating with kids with problem behaviors, to calculate a child’s propensity for joining a gang, and then compared 173 youth who had joined a gang with 173 who did not but showed a similar propensity for doing so. The average age of joining a gang was just under 15 years old and the majority (60 percent) were in a gang for three years or less.
The study found that subjects between ages 27 and 33 who had joined a gang in adolescence were:
- Nearly three times more likely to report committing a crime,
- More than three times more likely to receive income from illegal sources
- More than twice as likely to have been jailed in the previous year
- Nearly three times more likely to have drug-abuse problems
- Nearly twice as likely to say they were in poor health
- Twice as likely to be receiving public assistanÎ
- Half as likely to graduate from high school.
The study was funded by the National Institute on Drug Abuse the Robert Wood Johnson Foundation, and the National Institute on Mental Health.

Stroke Survivors May Lose a Month of Healthy Life for Every 15-Minute Delay in Treatment
Every 15-minute delay in delivering a clot-busting drug after stroke takes away about a month of a healthy life for stroke survivors, according to a new study in the journal Stroke. Researchers at the University of Melbourne in Australia analyzed data from clot-busting trials and applied the time to efficacy to over 2,000 stroke cases in Australia and Finland to calculate what the patient outcomes would have been if they had been treated faster or slower. They found that for every minute the treatment could be delivered faster, patients gained an average 1.8 days of extra healthy life. The researchers also found that while all patients benefited from faster treatment, younger patients with longer life expectancies gained more than older patients

One in Five Older Americans Take Medications that Work Against Each Other
More than 20 percent of older Americans take Medicines that work at odds with each other, and in some cases the medication being used for one condition can actually make the other condition worse, according to a new study in the online journal PLUS One by researchers at Oregon State University and the Yale School of Medicine. The study was conducted by researchers from OSU and Yale with 5,815 community-living adults over a two year period.
“Many physicians are aware of these concerns but there isn’t much information available on what to do about it,” says David Lee, an assistant professor in the Oregon State University/Oregon Health & Science University College of Pharmacy. “As a result,” says Lee, “right now we’re probably treating too many conditions with too many medications. There may be times it’s best to just focus on the most serious health problem, rather than use a drug to treat a different condition that could make the more serious health problem even worse.”
The chronic conditions in which competing therapies are common include coronary artery disease, diabetes, COPD, dementia, heart failure, hypertension, high cholesterol and osteoarthritis and others.

Hypertension Often Untreated in U.S. Hispanic Community
A new study in the American Journal of Hypertension finds that there is too little recognition and control of hypertension among the Hispanic population of the United States.
The new data comes from the Hispanic Community Health Study/Study of Latino, a longitudinal study of 16,415 Hispanics/Latinos, ages 18 to 74 years from four communities in the U.S. (Bronx, Chicago, Miami, and San Diego). Measures including hypertension levels and whether patients were on hypertension medications were collected between 2008 and 2011 and then followed up last year.
The study also found that the prevalence of hypertension in the Hispanic community increased with age, and was highest among those with Cuban, Puerto Rican, and Dominican backgrounds.

Majority of Youth C. Difficile Infections Linked to Doctor Visits
Antibiotics prescribed in a doctor’s office for other conditions are associated with the majority of Clostridium difficile infections, according to a new study in the journal Pediatrics. Researchers from the U.S. Centers for Disease Control and Prevention (CDC) determined that 71 percent of the cases for youth ages 1-17 were linked to the visits, rather than to overnight stays in health care facilities; two-thirds of adult cases are linked to hospital stays. The findings raise the profile of ongoing efforts to reduce unnecessary prescriptions. “Improved antibiotic prescribing is critical to protect the health of our nation’s children,” said CDC Director Tom Frieden, MD, MPH. “When antibiotics are prescribed incorrectly, our children are needlessly put at risk for health problems including C. difficile infection and dangerous antibiotic resistant infections.” Read more on prescription drugs.
Study: Even Slightly Elevated Blood Pressure Can Do Cardiovascular Damage Over Time
Even slightly elevated blood pressure that does not rise to the clinical definition of hypertension can do cardiovascular damage over time, according to a new study in the Journal of the American Medical Association. Researchers at the University of Oklahoma Health Sciences Center analyzed blood pressure data on more than 4,600 participants, all of whom had their readings tracked over 25 years from young adulthood to middle age. They placed the participants in five blood pressure trajectory categories:
- Low-stable: blood pressure that starts low and stays low
- Moderate-stable: blood pressure that begins only slightly elevated and stays that way
- Moderate-increasing: blood pressure begins only slightly elevated and increases over time
- Elevated-stable: blood pressure that starts at elevated levels, but does not increase
- Elevated-increasing: blood pressure that begins elevated and increases over time
The study determined that participants in the moderate-stable group were 44 percent more likely to have coronary artery calcification than those in the low-stable group. Read more on heart health.
Study: Men Die Earlier in More Patriarchal Societies
Gender differences when it comes to mortality rates are higher in more patriarchal societies, meaning women’s rights are good for men’s health, according to a new study in the American Psychological Association’s Evolutionary Behavioral Sciences. Utilized sociodemographic and mortality data from the World Health Organization, researchers from the University of Michigan (UM) School of Public Health found that men living in the top 25 percent most-patriarchal societies were 31 percent more likely to die than men in the least patriarchal quartile, compared to mortality rates for women. Researchers noted that the study only included societies with infrastructures capable of providing reliable data, so the difference could be even more pronounced. Possible explanations include:
- Males in societies where they are more socially dominant tend to engage in riskier behaviors that can lead to death.
- These societies tend to have more resources and social status concentrated in a smaller group of elite men, and men with greater control of resources and social status historically have had more reproductive success.
- In their quest for social dominance, men will go up against other men to gain power and engage in forms of competitive, and sometimes dangerous, behavior.
"Gender inequality is inherently related to inequality in general, and this is bad for both men and women's health, though especially harmful to men in increasing the risk of death," said UM researcher Daniel Kruger. Read more on health disparities.
HHS, Heart Disease Organizations Join Forces to Vastly Reduce Premature Death Linked to Heart Conditions by 2025
Leaders from the World Heart Federation , the American Heart Association, the U.S. Department of Health and Human Services, and the American College of Cardiology are joining together to help cut premature mortality from cardiovascular disease by at least 25 percent by 2025. Key strategies will include secondary prevention efforts for people who have already experienced a heart incident, or have established heart disease, as well as primary prevention strategies in the United States and around the world. “Heart disease can touch anyone, no matter where you live,” said Nancy Brown, chief executive officer of the American Heart Association. “It will take the collective efforts of everyone from community leaders to healthcare professionals, educators and business leaders to stop this No. 1 killer at the national and global level...” Read more on heart health.
New Guidelines for Stroke Risk, Prevention in Women
The American Heart Association/American Stroke Association has published the first ever set of guidelines dedicated to stroke risk and prevention in women. The 86-page document appears in the journal Stroke and address risk factors distinct to women, including pregnancy, oral contraceptives, menopause and hormone replacement. It also covers factors that affect women more than men, including atrial fibrillation and migraine with aura. “We reviewed a large body of research to be able to summarize our current understanding of stroke risk and stroke prevention in women, information that is critically important for care providers and researchers in the field,” according to Judith Lichtman, MD, associate professor at the Yale School of Public Health and co-author of the study. “The guidelines are also important to empower women and their families to better understand their risk for stroke and be aware of ways they can minimize their likelihood of having a one.” Strokes are the third-leading cause of death among women in the United States.

Study: Indicators of Potential Heart Disease as Early as Age 18
Indicators of potential heart disease can be seen as early as age 18, according to a long-term study recently published in the Journal of the American Medical Association. Researchers found that elevated blood pressure at that age, as well as found distinct blood pressure patterns from ages 18-55, indicate people at high risk for calcification of coronary arteries by middle age. “This shows that your blood pressure in young adulthood can impact your risk for heart disease later in life,” said Norrina Allen, PhD, lead study author and assistant professor of Preventive Medicine at Northwestern University Feinberg School of Medicine, in a release. “We can’t wait until middle age to address it. If we can prevent their blood pressure from increasing earlier in life we can reduce their risk of future heart attacks and stroke.” Approximately one in three U.S. adults have hypertension.

American Society of Clinical Oncology Weighs in on Mammography
In response to a study published this week in the British Medical Journal which called into question the benefit of mammography, the American Society of Clinical Oncology (ASCO) issued a statement today saying that because mammography is similar to many other tests that can detect a condition that may never cause harm, the benefits of screening are likely to be greater for women who are at increased risk of developing breast cancer based on factors such as age and family history, than for women at average risk. It also stated no single study should be used to change screening policy and that all women should be encouraged to speak with their doctors about their personal risk for breast cancer, as well as the potential benefits and harms of mammography screening. ASCO and other cancer advocacy and women’s health groups have announced that they will be monitoring additional mammography studies now being conducted, and the American Cancer Society is expected to release new mammography recommendations later this year.

NHTSA Announces New Mandatory Label to Help Owners Instantly Identify Recall Mailings
The U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) today announced that starting February 18, all manufacturers must use a distinctive label on the agency’s required mailings that notify owners of recalled vehicles or equipment.
The requirement was introduced to help owners instantly distinguish important recall notices arriving in their mailboxes from other mail and hopefully avoid mistakenly discarding the safety notices. NHTSA has also just launched the SaferCar app for Android devices that will provide information for car owners and shoppers, including recalls and safety performance. There is already a SaferCar app for iPhone, iPad and iPod Touch users. Other safety notification options from NHTSA include:
- Register Your Cars, Tires and Car Seats: Receive NHTSA email notifications when there is a recall by the federal government. There is no way to locate or notify individual owners of car seats or tires if the product is not registered with the manufacturer or NHTSA.
Check for Open Recalls on Used Cars: Verify with the previous owner or dealer whether a used car has been fixed by using www.safercar.gov, which provides a general search tool to help consumers identify recalls that may affect their vehicle.

AHA Releases Stroke Prevention Guidelines for Women
For the first time, the American Heart Association (AHA) has released stroke prevention guidelines for women. The guidelines outline stroke risks unique to women and provide evidence-based recommendations on how best to treat them, including:
- Women with a history of high blood pressure before pregnancy should be considered for low-dose aspirin and/or calcium supplement therapy to lower preeclampsia risks.
- Women who have preeclampsia have twice the risk of stroke and a four-fold risk of high blood pressure later in life. Therefore, preeclampsia should be recognized as a risk factor well after pregnancy, and other risk factors such as smoking, high cholesterol, and obesity in these women should be treated early.
- Pregnant women with moderately high blood pressure (150-159 mmHg/100-109 mmHg) should be considered for blood pressure medication; expectant mothers with severe high blood pressure (160/110 mmHg or above) should be treated.
- Women should be screened for high blood pressure before taking birth control pills because the combination raises stroke risks.
- Women who have migraine headaches with aura should stop smoking to avoid higher stroke risks.
- Women over age 75 should be screened for atrial fibrillation risks; a risk factor for stroke.

New Study Predicts Flu Severity
Researchers at St. Jude Children’s Research Hospital in Memphis say flu patients, regardless of age, who have elevated levels of three particular immune system regulators, called cytokines, early in the infection were more likely to develop severe flu symptoms and to be hospitalized than patients with lower levels of the same regulators. Study participants ranged in age from 3 weeks to 71 years.
The study, published in the American Journal of Respiratory and Critical Care Medicine, found that cytokine levels early in the infection were predictive of flu-related complications regardless of patient age, flu strain, the ability of the virus to replicate and other factors. The cytokines studied help to regulate inflammation caused by the body’s immune response to the flu until antibodies and T cells take over. Patients with the elevated cytokines seem to develop airway distress as a reaction to the immune response, a development separate from the effects of the flu virus. “We need to explore targeted therapies to address this problem separately from efforts to clear the virus, says study author Paul Thomas, PhD, an assistant member of the St. Jude Department of Immunology.

Community Health Worker Model Can Reduce Hospital Readmissions
A new study in JAMA Internal Medicine reports on a community health worker (CHW) program developed at the University of Pennsylvania School of Medicine that hired people from the local community to help discharged patients navigate the health care system and address key health barriers, such as housing instability or food insecurity. The study found that the intervention improved patient experiences and health outcomes and reduced hospital readmissions.
The Penn team tested the model in a randomized trial with 446 hospitalized patients who were either uninsured or on Medicaid, and lived in low-income communities in which more than 30 percent of the population lived below the Federal Poverty Level. More than one-third of all readmissions to the hospitals participating in the study come from a five-zip code region. Patients in the trial received support from CHWs hired for traits such as empathy and active listening. The CHWs connected during a patient's hospital stay and continued after they were discharged to help with issues including scheduling doctor appointments, accessing medications, or finding child care or shelter. The control group received routine hospital care, medication reconciliation, written discharge instructions, and prescriptions from the hospital. The CHW group had a 52 percent greater chance of seeing a primary care physician within two weeks after being discharged from the hospital and scores measuring a patient's confidence in managing their own care in the future more than doubled in the CHW group. While the two groups had similar rates of at least one hospital readmission (15 percent vs 13.6 percent), the CHW group was less likely to have multiple readmissions (2 percent vs 6 percent in the control group).

>>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 info@newPublichealth.org.
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.
