EBOLA UPDATE: Death Toll Passes 1,500 as Outbreak Accelerates
(NewPublicHealth is monitoring the public health crisis in West Africa.)
The West African Ebola outbreak continues to accelerate, according to the World Health Organization (WHO), which today announced there have so far been 3,069 probable and confirmed cases; 1,552 people have died. While most cases remain concentrated in only a few localities, WHO estimates that more than 40 percent of the total cases have occurred within the past 21 days.

Teens Who Don’t Get Enough Sleep Are at Increased Risk of Obesity
Teenagers who don’t get enough sleep are at increased risk of being obese by age 21, according to a new study in Journal of Pediatrics. Researchers at Columbia’s Mailman School of Public Health analyzed health information on more than 10,000 teens and young adults at the ages of 16 and 21, finding that the 16-year-olds who reported less than six hours of sleep per night were 20 percent more likely to be obese by age 21. Potential reasons for the link include appetite changes and cravings due to daytime sleepiness and fatigue. The U.S. Centers for Disease Control and Prevention recommends nine to ten hours of sleep per night for teenagers. Read more on pediatrics.
Study: ‘Rules of Thumb’ on Pouring Help Reduce Excessive Drinking
Curbing a person’s excessive drinking may be as simple as thinking about how much is poured into each glass, according to a new study in the International Journal of Drug Policy. Researchers from Iowa State University and Cornell University had 74 college students pour red or white wine in a variety of settings, finding that those students who use a “rule of thumb” to dictate their pours—such as only filling half the glass or leaving space equivalent to two fingers at the top—poured less, regardless of their BMI or gender. “About 70 percent of the people in the sample used the half-glass rule, and they poured significantly less by about 20 percent,” said Laura Smarandescu, lead author and an assistant professor of marketing at Iowa State, in a release. “It’s a big difference. We would suggest using a rule of thumb with pouring because it makes a big difference in how much people pour and prevents them from overdrinking.” Read more on alcohol.
Study: Families With Preschoolers Purchasing Fewer High-Calorie Drinks
Recent progress in stalling and perhaps even reversing the childhood obesity epidemic may be linked to fewer families with preschool-aged children purchasing high-calorie drinks, according to a new study in the American Journal of Preventive Medicine. Researchers used Nielsen Homescan data from approximately 43,000 U.S. households with young children from 2000 to 2011, identifying the top 20 foods and beverages purchased. “Decreases in purchases of fluid milks, soft drinks, juice and juice drinks, and grain-based desserts were the primary drivers of this change,” said lead author Christopher Ford, MPH, doctoral candidate in nutrition at the University of North Carolina’s Gillings School of Global Public Health. “These data suggest that these households may have purchased fewer calories from solid fats and added sugars.” Previous research shows that approximately 70 to 80 percent of a preschooler’s diet comes from food purchased at stores.

Peace Corps Withdraws from Three West African Countries Due to Ebola Crisis
The Peace Corps announced yesterday that it was removing all 340 of its volunteers from Liberia, Sierra Leone and Guinea in reaction to the increasing spread of the Ebola virus in West Africa. The organization said it has been working closely with experts from the U.S. Centers for Disease Control and Prevention and the U.S. Department of State to monitor the health crisis and determine how it should respond. “The Peace Corps has enjoyed long partnerships with the government and people of Liberia, Sierra Leone and Guinea and is committed to continuing volunteers’ work there,” according to a Peace Corps release. “A determination on when volunteers can return will be made at a later date.” Read more on global health.
Study: Women Who Live Near Green Spaces Give Birth to Healthier Babies
Pregnant women who live near green spaces—such as parks, community gardens and even cemeteries—give birth to healthier babies with significantly higher birth weights, according to a new study in the journal Occupational and Environmental Medicine. Researchers analyzed data on approximately 40,000 single live births in Tel Aviv, Israel. "We found that overall, an increase of surrounding greenery near the home was associated with a significant increase of birth weight and decreased risk for low birth weight," said Michael Friger, PhD, of Ben-Gurion University of the Negev's Department of Public Health. "This was the first study outside of the United States and Europe demonstrating associations between greenery and birth weight, as well as the first to report the association with low birth weight."

FDA Approves New Oxycodone with Abuse-deterrent Properties
The U.S. Food and Drug Administration (FDA) has approved a new extended-release oxycodone with abuse-deterrent properties. Targiniq ER—which should be used to treat pain severe enough to require daily, around-the-clock, long-term opioid treatment—contains naloxone which blocks the euphoric effects of oxycodone when crushed and snorted, or crushed, dissolved and injected. The drug is consistent with the FDA’s 2013 draft guidance for industry, Abuse-Deterrent Opioids – Evaluation and Labeling. "The FDA is committed to combatting the misuse and abuse of all opioids, and the development of opioids that are harder to abuse is needed in order to help address the public health crisis of prescription drug abuse in the U.S.,” said Sharon Hertz, MD, deputy director of the Division of Anesthesia, Analgesia and Addiction Products in the FDA’s Center for Drug Evaluation and Research. “Encouraging the development of opioids with abuse-deterrent properties is just one component of a broader approach to reducing abuse and misuse, and will better enable the FDA to balance addressing this problem with meeting the needs of the millions of people in this country suffering from pain.” Read more on substance abuse.
HHS: 10.3 Million Adults Gained Coverage in the ACA’s First Open Enrollment Period
An estimated 10.3 million uninsured adults gained health care coverage following the first open enrollment period in the Health Insurance Marketplace, according to a new study from the U.S. Department of Health and Human Services appearing the New England Journal of Medicine. The study looked at insurance trends before and after the open enrollment period, finding that the uninsured rate for adults ages 18-64 dropped from 21 percent in September 2013 to 16.3 percent in April 2014, which corresponded to a 5.2 percentage-point change, or 10.3 million adults gaining coverage.

Study: Parents of Obese Kids Often Don’t Realize They’re Unhealthy
Parents of obese children often don’t see their child’s weight as unhealthy and are more likely to make changes in their eating habits than to increase exercise, according to a new study in the Journal of the Academy of Nutrition and Dietetics. In a survey of more than 200 families in 2008 and 2009 to evaluate their readiness to help their children lose weight, researchers found that 28 percent of the parents did not see their child's weight as a health problem and 31 percent thought their child’s health was excellent or very good. The study also found that while 61 percent said they were trying to improve eating habits, only 41 percent were attempting to increase their child's activity level. Read more on obesity.
A 2012 report from the Robert Wood Johnson Foundation (RWJF) and Trust for America’s Health concluded that if the adult and childhood obesity rates in 2011 continued to increase at their steady paces, then by 2030 nearly two-thirds of U.S. adults would be obese and every single state would have obesity rates above 44 percent.
Data now show that childhood obesity rates have stabilized. In fact, for the first time in a decade the obesity rates among young children from low-income families in many states is trending down.
Helping lead the way in this important public health issue has been the city of Philadelphia, Penn., which has worked to improve access to healthy foods and opportunities for physical activity.
“We were very fortunate in Philadelphia to have colleagues...who have developed a better understanding of childhood obesity,” said Don Schwarz, former Health Commissioner and Deputy Mayor for Health and Opportunity, City of Philadelphia, and will also soon take on the role of director for RWJF’s Demand Team. “What that has meant is that Philadelphia was able to take a body of knowledge and bring it to scale. The partnership in Philadelphia that has allowed that to happen goes across government and between government and the private sector and community organizations—just everyday Philadelphians. So that kind of partnership, that wonderful knowledge base, has I believed turned the corner on childhood obesity, particularly for children who are of disadvantaged communities.”
Schwarz’s comments came during the Tuesday, July 22 Google Hangout TEDMED Great Challenges: A Candid Conversation About Childhood Obesity. The panel was moderated by Richard Besser, Chief Health and Medical Editor for ABC News.
Every member of the panel echoed the importance of partnerships, and Besser succinctly explained their critical role in not just obesity prevention but all public health efforts.
“The more creatively you can think and the wider variety of partners you can pull in, the more likely you are to be successful,” he said.
At the heart of Philadelphia’s success has been the important role that schools play in that community partnership. According to Schwarz, for the past decade the city’s schools have worked to reshape how they approach children’s health and wellbeing, including comprehensive nutrition policies, a new food environment that emphasizes healthy choices and more opportunities for kids to be physically active. One can’t be successful without the other.
Study: Global Child TB Rates 25 Percent Higher than Previously Realized
The true number of children who develop tuberculosis (TB) each year in the 22 countries with the worst TB rates is nearly 25 percent higher than the World Health Organization (WHO) estimated as recently as 2012, according to a new study in The Lancet Global Health. Researchers used mathematical modeling to determine that approximately 650,000 children in these countries develop TB each year; the WHO estimate was 530,000. The study also determined that approximately 15 million children are exposed to TB every year and 53 million are living with latent TB infections which can become infectious active TB. While the findings are troubling, they also indicate promising ways to reduce the risk. "Our findings highlight an enormous opportunity for preventive antibiotic treatment among the 15 million children younger than 15 years of age who are living in the same household as an adult with infectious TB,” said lead author Peter Dodd, MD, from the University of Sheffield in the United Kingdom, in a release. "Wider use of isoniazid therapy for these children as a preventative measure would probably substantially reduce the numbers of children who go on to develop the disease." Read more on global health.
Severe Obesity Can Cut a Person’s Lifespan by Nearly 14 Years
Severe obesity can take nearly 14 years off a person’s life, according to a new study in the journal PLOS Medicine. Using data from 20 previous studies, researchers determined that severe obesity—defined as a body mass index (BMI) greater than 40—can cut lives short by anywhere from 6.5 to 13.7 years, due to increased risk of health problems such as heart disease, cancer and diabetes. "We found that the death rates in severely obese adults were about 2.5 times higher than in adults in the normal weight range," said lead investigator Cari Kitahara, a research fellow at the U.S. National Cancer Institute, according to HealthDay. Approximately 6 percent of U.S. adults are severely obese; severe obesity accounts for approximately 509 deaths per 100,000 men annually and 382 deaths per 100,000 women annually.

HHS: $100M for 150 New Community Health Centers
The U.S. Department of Health and Human Services (HHS) has announced approximately $100 million in available funds for communities to expand access to affordable, high-quality primary care through an estimated 150 new community health centers in 2015. Currently there are approximately 1,300 health centers with more than 9,200 service sites providing care to more than 21 million people in the United States and its territories. The centers, made possible under the Affordable Care Act (ACA), have also helped approximately 4.7 million people enroll for ACA coverage. Read more on community health.
Application Problems Mean 2.2M People Risk Losing ACA Coverage
Inconsistencies in their application data means that approximately 2.2 million people who enrolled for coverage under the Affordable Care Act could risk losing their coverage in isolated cases. A report from the U.S. Centers for Medicare and Medicaid Services (CMS) found that 1.2 million people filed health insurance enrollment applications with questionable income data, 461,000 had issues with citizenship and another 505,000 had issues with immigration. However, CMS also noted that 59 percent of the applications were within a 90-day window allowing them to resolve the problems. “Consumers experience regular changes in income and various life circumstances and the law accounts for these kinds of situations," said CMS, according to Reuters. "It is not surprising that there are income discrepancies given that this is a brand new process." As of mid-April more than 8 million people had enrolled for health coverage.

Study: Skipping Breakfast Doesn’t Hurt Efforts to Lose Weight
Common wisdom holds that people who skip breakfast actually increase their risk of obesity. However, a new study in the American Journal of Clinical Nutrition found that passing up on the first meal of the day neither helps nor hurts a person’s efforts to lose weight. The study involved 309 overweight and obese adults between the ages of 20 and 65—who were told to either eat or skip breakfast—and a control group provided with health nutrition information. Researchers found no difference when it came to efforts to lose weight. "The field of obesity and weight loss is full of commonly held beliefs that have not been subjected to rigorous testing; we have now found that one such belief does not seem to hold up when tested," senior investigator David Allison, director of the UAB Nutrition Obesity Research Center, said in a university news release. "This should be a wake-up call for all of us to always ask for evidence about the recommendations we hear so widely offered." Read more on obesity.
HHS: $300M Available to Expand Services at Community Health Centers
An additional $300 million in funding is available to community health centers as part of the Affordable Care Act, U.S. Health and Human Services Secretary Kathleen Sebelius announced this week. The funds will go toward expanding service hours and the hiring of more medical providers, as well as the expansion or addition of oral health, behavioral health, pharmacy and vision services. There are approximately 1,300 health centers operating more than 9,000 service delivery sites and providing care for more than 21 million U.S. patients. Read more on community health.
CDC: Man Previously Reported Having MERS Does Not Harbor the Virus
After completing additional and more definitive laboratory tests, the U.S. Centers for Disease Control and Prevention (CDC) has retracted a report made last week that an Illinois man contracted the potentially deadly MERS virus from a patient who was diagnosed with MERS in the United States after spending time as a health care worker in Saudi Arabia. The confusion over the diagnosis came from earlier tests that indicated antibodies to a coronavirus, the class of virus MERS belongs to. However, more definitive tests found that he did not harbor the MERS virus. There are six known versions of the coronavirus; four cause mild illness and two cause the much more serious MERS and SARS viruses. Read more on infectious disease.
Study: 30 Percent of the World’s Population is Obese
A new analysis of global obesity trends finds that approximately 2.1 billion people—or nearly 30 percent of the world population—are obese, according to a new study in The Lancet. Researchers found that rates of being obese or overweight climbed 20 percent in adults and 47 percent in children during the 33 years analyzed. The study, which was funded by the Bill & Melinda Gates Foundation, determined that while obesity was once more common in wealthier nations, approximately two-thirds of the world’s obese population lives in developing countries. In addition, the statistics for the United States were especially troubling; while only 5 percent of the world’s population lives in the United States, the country is home to approximately 13 percent of the world’s obese population.

Study: Lung Cancer Screening Can Scare People into Quitting Smoking
In addition to early detection and treatment of lung cancer, early screening can also scare people into quitting smoking before they even develop the disease, according to a new study in the JNCI: Journal of the National Cancer Institute. Researchers based their findings on an analysis of 14,621 current smokers, 55-70 years old, with a 30 or more pack-year smoking history and who had smoked during the last 15 years. The data was taken from the Lung Screening Study component of the U.S. National Lung Screening Trial. The study found that "...abnormal screening results may present a 'teachable moment'" and that "[f]uture lung cancer screening programs should take advantage of this opportunity to apply effective smoking cessation programs."

OECD: Economic Crisis Contributed to Global Obesity Crisis
More people than not in the member countries of the Organization for Economic Co-operation and Development (OECD) are obese, with the economic crisis that began in 2008 contributing even more to the overall increase in body weight and obesity, according to a new OECD report. The analysis found that many of the people and families in the countries hit hardest by the economic crisis were forced to turn to less expensive—but also less healthy—food. For example, from 2008-2009 households in the United Kingdom decreased their food expenditure by 8.5 percent in real terms, while also increasing the average calorie density of purchased foods by 4.8 percent.
Among the other findings:
- One in 5 OECD children are overweight or obese
- The obesity epidemic has spread further in the past five years, but rates have been increasing at a slower pace than before
- People with less education and lower socio-economic status are more likely to be obese, and the gap is generally larger in women
- A growing number of countries have adopted policies to prevent obesity from spreading further

Study: 1 in 5 Medicare Patients Experience Medical Injuries
Approximately 20 percent of Medicare patients experience medical injuries, which are often not linked to any underlying disease or condition, according to a new study in the journal Injury Prevention. Typical injuries include being given the wrong medication, having an allergic reaction to a medication, or receiving any treatment that led to more complications of an existing medical problem. Using data on more than 12,500 Medicare patients who made claims between 1998 and 2005, researchers found that 19 percent experienced at least one adverse medical event and 62 percent of the injuries took place during outpatient care. The highest risks were scene in older people, men and those from lower-income backgrounds. "These injuries are caused by the medical care or management rather than any underlying disease," said lead researcher Mary Carter, director of the Gerontology Program at Towson University in Maryland. "To really improve our ability to prevent these types of adverse events, we have to focus at least as much on outpatient care as we do on inpatient care." Read more on injury prevention.
Salmonella Outbreak Causes an Additional 50 Cases; Total Now at 574
With an additional 50 cases, the salmonella outbreak linked to Foster Farms chicken that began in March 2013 now has sickened a total of 574 people, according to the U.S. Centers for Disease Control and Prevention (CDC). The CDC estimates there have been an average of eight new cases per week since an April report on the drug-resistant Salmonella Heidelberg. Thirty-seven percent of the cases have led to hospitalization and about 13 percent have developed blood infections, which is three times higher than what’s seen with typical salmonella infections.

Faster Mass Vaccination Response Could Save Lives, Costs in a Flu Pandemic
A faster response of mass vaccinations after the start of a severe flu outbreak would save both lives and health care costs, according to a new study in Annals of Internal Medicine. Researchers created a computer model of a how an outbreak of H7N9 or H5N1 would affect a U.S. metropolitan city with characteristics similar to New York City, depending on when public health officials were able to vaccinate 30 percent of the population. They determined that reaching that vaccination target in 12 months would mean 48,254 persons would die; at 9 months would save an additional 2,365 lives; at 6 months would save an additional 5,775 lives and $51 million at a city level; and at 4 months would save an additional 5,633 lives and $50 million.

Study: Current Weight at 25 a Better Indicator of Later Obesity Risk than Duration of Obesity
In a study of the relationship between body mass index (BMI) at age 25, obesity later in life and biological indicators of health, researchers determined current weight—and not the duration of obesity—was a more effective indicator of cardiovascular and metabolic risk, according to a new study in the American Journal of Preventive Medicine. They did also note that people who were obese by age 25 were in fact at higher risk of more severe obesity later in life. Using data from the 1999-2010 U.S. National Health and Nutrition Examination Survey (NHANES), the study found that men who were obese at age 25 had a 23.1 percent estimated probability of class III obesity (BMI greater than 40) after age 35, compared to a 1.1 percent chance for men of a normal weight at age 25. For women who were obese at age 25 the risk of later class III obesity was 46.9 percent, compared to only 4.8 percent for women of a normal weight. “This is good news in some respects, as overweight and obese young adults who can prevent additional weight gain can expect their biological risk factors to be no worse than those who reach the same level of BMI later in life,” said study lead author Jennifer B. Dowd, MD, associate professor, epidemiology and biostatistics, City University of New York (CUNY) School of Public Health, Hunter College. Read more on obesity.
Higher High School GPAs Linked to Greater Earnings in Adulthood
A one-point increase in high school grade point average (GPA) can raise annual earnings in adulthood by approximately 12 percent for men and 14 percent for women, according to a new study in the Eastern Economic Journal. Researchers also determined that a 1-point increase in GPA increased the likelihood of completing college from 21 percent to 42 percent for both genders. “Conventional wisdom is that academic performance in high school is important for college admission, but this is the first study to clearly demonstrate the link between high school GPA and labor market earnings many years later,” said Michael T. French, director of the Health Economics Research Group (HERG) in the Department of Sociology at the UM College of Arts and Sciences, and corresponding author of the study, adding, “High school guidance counselors and teachers can use these findings to highlight the importance of doing well in high school for both short term (college admission) and longer term (earnings as an adult) goals.” Read more on education.
Tornadoes Kill At Least 17 in South Central U.S. Over the Weekend
Multiple tornadoes, damaging winds and hail storms over the weekend resulted in 17 deaths in Arkansas and Oklahoma, according to reporting by the Weather Channel. More severe weather is expected in the South and Midwest through Wednesday. According to reporting by Reuters, the hardest hit area was Faulkner County in Arkansas, where 10 people died and cars and homes were destroyed. The Red Cross has opened several shelters in the area.

Study: Almost Half of Homeless Men Previously Suffered a Traumatic Brain Injury
Almost half of all homeless men who took part in a study by researchers at St. Michael’s Hospital in Toronto had suffered at least one traumatic brain injury (TBI) in their lives and 87 percent of those injuries occurred before the men lost their homes, according to the study authors. Some men suffered more than one TBI and the researchers found that assaults accounted for 60 percent of the injuries; sports and recreation accounted for 44 percent; and car accidents and falls accounted for 42 percent.
The fact that so many homeless men suffered a TBI before losing their home suggests such injuries could be a risk factor for becoming homeless, said lead researcher Jane Topolovec-Vranic, PHD, a clinical researcher in the hospital’s Neuroscience Research Program. Topolevec-Vranic said the study underscores the need to monitor young people who suffer TBIs such as concussions for health and behavioral changes. In men under age 40, falls from drug/alcohol blackouts were the most common cause of traumatic brain injury, while assault was the most common in men over 40 years old. The study was published in the journal CMAJ Open. Read more on injury prevention.
People on Statins More likely to Eat Foods that Can Lead to Obesity Related Illnesses
A new study led by researchers from UCLA suggests that people who took statins in 2009–10 were consuming more calories and fat than those who used statins 10 years earlier. There was no similar increase in caloric and fat intake among non-statin users during that decade according to the study in JAMA Internal Medicine. "We believe that this is the first major study to show that people on statins eat more calories and fat than people on those medications did a decade earlier," said the study's primary investigator, Takehiro Sugiyama, a visiting scholar at the David Geffen School of Medicine at UCLA. "Statins are used by about one-sixth of adults. We may need to reemphasize the importance of dietary modification for those who are taking these medications...”
The study authors used data from the National Health and Nutrition Examination Survey to compare fat and caloric intake among statin users and non-users in 1999–2000 and 2009–10. They found that caloric intake among statin users had risen by 9.6 percent over that decade and that fat consumption had jumped by 14.4 percent. In contrast, caloric and fat intake by non-statin users did not change significantly during the 10-year period. Read more on obesity.
